What is the impact of the performance of solid tires on the performance of the vehicle?

Influence of Solid Tire Performance on Vehicle Performance (1), the impact on the power performance of the forklift The entire cross-section of the solid tire plant is composed of rubber and cord fabrics of different formulations, and its internal friction must exceed that of pneumatic tires. Because the quality of life of solid tire companies is higher than that of pneumatic tires of the same specification, the social resistance and ramp resistance of their development acceleration are also larger. (2), the impact on the performance of the braking system The braking force of the forklift mainly depends on the braking system torque provided by the brake work and the adhesion of the road surface. Sufficient braking force can be obtained only when the forklift has sufficient braking torque and the ground can provide sufficient adhesion. Solid tires may have poorer adhesion system performance than pneumatic tires of the same specification. Therefore, the braking force of a solid tire is less than that of a pneumatic tire of the same specification. At the same time, solid tires have a greater impact on the product quality of pneumatic tires of the same specification. Therefore, under the same initial braking speed, the braking deceleration of Chinese tire forklifts is relatively small, and the braking system distance is relatively large. Therefore, in the case of the same specification, the braking system of a solid tire forklift will be poor. (3), the impact on the passability of the forklift For tires of the same specification, since the shape and size of the pneumatic tire is larger than that of the solid tire, the clearance between the forklift and the ground can be increased, so the passing performance of the pneumatic tire forklift is better.

What is the emergency treatment for the damaged solid rubber tire?

At present, solid rubber tires are generally only used in high-load vehicles and machinery running at low speeds, and are also used in fixed-position machinery compared with pneumatic tires, because solid rubber tires are more wear-resistant. How to deal with the damaged solid tire of forklift truck? Let's popularize it with Zhejiang Kunrong Rubber Technology Co., Ltd. below! 1. When the inner tube is found to have small holes, it can be hot or cold. File the roughness around the damage of the inner tube, stick the fire repair glue on the damage, and make the hole just in the middle of the repair glue, then install the tire repair clip against the normalizing glue, tighten the screw and then ignite The heating agent on the fire repair glue can be tightly bonded after 10-15 minutes. 2. When the outer tire of the solid rubber tire has cracks, holes, blistering, delamination and other damages, it should be repaired or renovated according to the specific conditions. When there are successive cracks around the tire carcass, the tread rubber has been polished and there are large holes, the carcass line layer has annular ruptures and the whole circle is separated, it should be replaced in time. 3. To be replaced in time: If the inner tube has problems such as folding, serious rupture, aging, stickiness, deformation, etc. that cannot be corrected, it needs to be replaced in time. Develop to check the tire pressure regularly, as far as possible, check it every other month. If the tire pressure is not enough, you should make up for it in time. Everyone should also check regularly before going on the highway to ensure the safety of driving.

Do you know the correct way to replace solid tires?

Replacing solid tires is a common problem encountered by many drivers and repairers. It is not an easy job, and it is necessary to understand the corresponding methods and skills. Let's take a look at it together. 1. First use a hydraulic jack to jack up the body structure Use a wrench to loosen the screws before jacking up the body, as it won't work if the wheel is in the air. The hydraulic control jack should be placed on a flat ground, and it should be avoided that there is no fulcrum and instability. Just jack up the car until the tires are off the ground. 2. Then turn the screw Before turning the screw, place the spare tire on the bottom of the car, so that we can effectively avoid the hydraulic control jack in the process of screwing the design. In the process of screw design, the wrench and the ground are at a 45-degree angle, which can better control the force. 3, followed by unloading the tire. In the process of unloading the tire, if the Chinese tire is too stuck, you can alternately kick the left, right and lower parts of the tire with your feet to make the tire loose. When you move the tires with your hands, cover your hands with gloves or a cloth as much as possible. Stains and oil on tires are no ordinary dust. It's hard to find a place to wash your hands after changing tires at a loss (movie). 4. Finally install the tires. The weight of solid tires and wheels is still very heavy. If we want to install Chinese tires at one time, can it be easy? You can cover the tire first, and then align the screw holes. When screwing a screw, you must strictly follow the principle of students' diagonal screwing. After screwing a production screw, screw the screw at the opposite corner. Do not screw clockwise or counterclockwise one by one.

What measures should be taken after the solid tire is worn out?

Compared with pneumatic tires, solid tires have higher wear resistance and stability. This performance is used for industrial vehicles such as low-speed and heavy-load hoisting vehicles, tractor vehicles, and flat scooters. As an important part of engineering vehicles, tires are used correctly or not, which directly affects the performance of various performances and the length of service life of the vehicle. What should be done if damage occurs? Damage treatment of solid tires: 1. When the tire has cracks, holes, blistering, delamination and other damages, it should be repaired or renovated according to the specific situation. When there are successive cracks around the tire carcass, the tread rubber has been polished and there are large holes, the carcass line layer has an annular rupture and the whole circle is separated, it should be replaced. 2. When the inner tube is found to have small holes, it can be hot or cold. File the roughness around the damage of the inner tube, stick the fire repair glue on the damage, and make the hole just in the middle of the repair glue, then install the tire repair clip against the normalizing glue, tighten the screw and then ignite The heating agent on the fire repair glue can be tightly bonded after 10-15 minutes. 3. Timely replacement: If the inner tube has problems such as folding, serious rupture, aging, stickiness, deformation, etc. that cannot be corrected, it needs to be replaced in time. Develop together to check the tire pressure regularly, try to check it every other month, if the tire pressure is not enough, it should be made up in time. Routine inspections are also required before boarding the expressway to ensure driving safety. In the process of daily use of solid tires, because many car owners ignore the condition of tires, it is easy to cause accidents. As long as you pay attention to inspection and maintenance, and develop good driving habits, you can travel the world with peace of mind.

Solid tires, new tires have longer braking distance than old tires?

Solid tires are one of the more important parts of a car and a safety barrier. Only a person who correctly understands various professional knowledge of tires can match our own car with tires suitable for students' own models. Today, Zhejiang Kunrong Rubber Technology Co., Ltd. will give you a detailed introduction to some knowledge of tires. Tires are one of the most important parts and technologies in automobiles, and they are also a barrier to national security. Understanding "12.00-20 20PR" means that there is no difference, so that you can choose the correct size of "shoes" for your car, but this It is far from enough. Whether the tire company is suitable for the car and whether it meets the market demand depends on the key performance indicators such as "wear resistance index" and "wet adhesion". We can ignore too much boring data, and the main analysis Explain some common but easily overlooked tire development problems. Do new tires actually brake longer than old tires? This social problem seems very illogical to us. The tread pattern of old tires has almost worn down to an important indicator line in China. How can we develop new tires with deeper tread patterns and shorter braking distances? Some tire testing agencies conduct specialized studies. Let’s talk about the conclusion first, we have no direct relationship between the tread depth and the braking distance. Older tires perform better on braking distances because their nearly smooth tread allows them to make more contact with the ground, creating more traction. Of course, the new tire company has a deeper tread, drainage and naturally better than the old tire, and the handling behavior on wet roads and rain will be better.

What is the reason for the peeling phenomenon of environmentally friendly solid tires in summer?

Solid tires are tires with excellent wear resistance and less heat generation composed of four parts: ply, bead, buffer layer, and tread. Due to the high temperature in summer, the temperature of the road surface is also very high under long-term exposure to the sun, and when solid tires are driven on such a high-temperature road surface, it is found that sometimes the tires that have not been used for a long time have peeled off. Today Let's follow Zhejiang Kunrong Rubber Technology Co., Ltd. Learn more about this issue. The peeling of solid tires is sometimes related to the selection and installation of tires. Whether the solid tire installation is directly related to the service life of the tire, especially when replacing tires, tires with different types and patterns, because the actual size and fit of each solid tire are different, so it must not be arbitrarily mixed. . At the same time, the tire pressure of solid tires must also be adjusted well. Too high or too low tire pressure is unscientific, which will affect the service life of solid tires. If the tire pressure is too low, its radial deformation will increase, the sides of the tire wall will be deformed excessively, and the wear of the crown and shoulders will occur, which will increase the temperature of the tire and seriously reduce the service life of the tire. In addition to the tire pressure of solid tires, the cleaning of solid tires is also very important. Before or after driving, check whether there are hard objects such as stones, iron blocks or nails in the tire grooves. If there are, clean them immediately. Solid tires are now widely used in various fields. At the same time, we do not recommend that tires be stored in wet places. If environmental conditions cannot be prevented, we also recommend proper maintenance of tires to extend the use of tires.

Should the debris in solid tires be cleaned regularly?

Due to long-term contact with the road, solid tires will inevitably embed stones in the tire markings, not only the texture is messy, but also the stones in the markings will hit the ground when driving, making a knocking sound. For us, does this crushed stone embedded in the tire texture need to be sorted? What's the harm in it? ①Affecting noise: Because the sound of the tires is relatively small when the company is running normally, and because the rubber tread in our country is relatively soft, but we will not have the same after embedding stones. And the gravel in the stripes will roll with the tires and hit the ground hard, as if someone was slammed into the ground and clashed, the rapid clattering sound is almost maddening. ② Prevent urban drainage: If the Chinese tire markings can act as a water guide when driving in rainy days, it can ensure that the tires can quickly shake off the liquid on the tires when driving through the water, and ensure that the grip of the tires in my country is not strong. There will be a drop to too much. If too much gravel is embedded in the Chinese tire pattern, it will significantly reduce the level and the drainage of the tire, causing the Chinese tire to skid. ③Danger of puncture: Although the tire tread has a solid comparison and research, it is usually difficult to directly pierce the stones that can be embedded in the markings, but if you drive too much at night, you will hit ghosts, and if you drive too much, we will inevitably embed sharp and strong stones The stone culture and even Chinese metal blocks, it is also possible for the enterprise to pierce the tire wall at this time. On the other hand, when the car is running at high speed, the high-speed conflict will cause the tire temperature to rise, the air in the tire to expand, and the tire wall thickness to become thinner. If there are some sharp stones embedded in the markings, it is easy to blow the tire at this time. In addition, the gravel in the tire pattern has to go through the double kneading and conflict between the sidewall and the ground, and some exposed outside the tread will soon be ground flat. And in the process of grinding, if the Chinese car market travels at a high speed, the gravel will easily sputter out in time, and the impact force is not small, which will damage your own car or other vehicles driving beside it.

How to deal with tire wear?

During the long-term use of solid tires, there may be wear and tear, so how to solve the wear and tear? Zhejiang Kunrong Rubber Technology Co., Ltd.'s measures to solve tire wear are as follows: 1. Cracks in the tire casing and perforated foam should be replaced if there are continuous cracks around the carcass, or when the tread rubber has been polished and there are large holes, and the carcass line layer has annular cracks and separation. 2. When the inner tube has small holes, it can be hot or cold. After roughening the damaged area of the inner tube, stick the fire repair glue on the damage, so that the holes can be in the center of the repair glue, then install the tire repair clip against the normalizing repair glue, and tighten the screw of the machine to tighten it again. Ignite the fire to make up the glue, wait for 10-15min, and then it can be bonded. 3. If the inner tube is stretched, severely cracked, brittle, sticky, or deformed, it cannot be corrected and must be replaced immediately.

What are the types of solid tire patterns?

The main function of the solid tire pattern is to prevent the wheel from slipping by increasing the friction between the tread and the road surface. The patterning of the tire not only improves the elasticity of the tread grounding system, but also under the action of the driving force, braking force and lateral force between the tread and the road surface, the pattern block can produce significant tangential elastic structural deformation. There are mainly the following categories: 1. Straight groove pattern: This traditional pattern has excellent operation stability, low rotational resistance and low noise, especially for drainage systems, which are not easy to pass laterally slip. The reason why it is called the normal mode is related to the off-road mode and the mud and snow mode. In fact, there are many types of common patterns in general, because each of our large tire manufacturers has its own laboratory and testing ground, where countless engineering information technology managers can study patterns. Anyone but in the process of research, think, pay 2. Horizontal groove pattern: The driving force, braking force and traction force of the horizontal groove pattern are particularly good, and its wear-resistant material performance is excellent. Therefore, it is very suitable for engineering management vehicles such as bulldozers and excavators. The performance of the drainage system is relatively poor. 3. Mud and snow pattern: The Mud and Snow pattern, as the name suggests, is designed for Mud and Snow patterns. When using this type of tire, be sure to remove the cleats on the tread, otherwise, it will damage the road surface, because we need many drivers to buy this type of tire, which does not exist for use in snow.

What are the instructions for the use of polyurethane solid tires?

Polyurethane is widely used in tire manufacturing in various industries. It has strong impact resistance, abrasion resistance, hydrolysis resistance, tensile strength, tear strength, oil resistance, etc., but it should also be used safely. , the following Zhejiang Kunrong Rubber Technology Co., Ltd will share with you the instructions for the use of polyurethane solid tires. Instructions for use are as follows: 1. When the wind pressure of the polyurethane solid tire is too low, the rolling resistance of the tire will become larger, which will cause abnormal heat and stress, and cause the tire to be partially peeled off and damaged; 2. When the wind pressure of the polyurethane solid tire is too high, not only will the ground contact area be small and the braking performance of the tire will be reduced, which will affect the driving safety, but also the driving comfort will be deteriorated due to the ability of the tire to absorb vibration frequency; 3. Different types of tires with different patterns or old and new tires should not be installed on the same axle; 4. The abnormal load will cause the tire to be overloaded and fail. Please ride in accordance with the load limit of the depot, and do not overload; 5. Overspeeding will cause the internal temperature of the tire to rise excessively, and the reduction of the rubber adhesion will eventually lead to failure; 6. Before combining the rim and tire of the polyurethane solid tire, please clean the rim and tire first, and no debris should be left inside.

How do polyurethane tires solve the slipping state?

When using polyurethane tires, it is inevitable to encounter wheel slippage. How to solve this problem, let Zhejiang Kunrong Rubber Technology Co., Ltd. introduce it to you. How to get out of a skid: Slips can happen to even the more cautious driver. If the vehicle is slipping, remember not to press the brake pedal hard. If your vehicle is equipped with an anti-lock braking system (ABS), do not apply the brakes. Instead, you should press the brake pedal firmly and steadily and turn the steering wheel in the direction of the slip. Get ready for the road: Driving with polyurethane solid tires on slippery surfaces requires gentle handling of all major controls (steering, clutching, braking, and accelerator) and constant alertness for accidents and emergencies ahead. When you're on the road in the rain, your shoes can get wet and easily slip off the pedals when you pedal. Before starting the engine, the soles of your shoes should be wiped dry on the car's carpet or rubber feet. All car drivers should regularly check that their car's headlights, taillights, brake lights, and turn signals are working properly. Slippery polyurethane solid tires to avoid braking: Avoid braking. Slow down as much as possible by releasing the gas pedal. Headlights should be turned on even in light rain. Not only does this help you see what's going on on the road, it also helps other drivers see your vehicle. If your vehicle is equipped with daytime running lights, they should be turned on so that vehicles behind can better keep their distance from you.

What are the structural characteristics of polyurethane solid tires?

Polyurethane solid tires and rubber solid tires are widely used in reach forklifts, narrow aisle forklifts, side/multi-directional forklifts, electric stackers, pallet trucks, pallet stackers used in various warehouses, supermarkets, and distribution centers. It is also used for the transmission, guidance and support of industrial and mining metallurgy and equipment assembly lines. The high strength, high load-bearing, high resilience, high wear resistance, high tear resistance and other properties of polyurethane solid tires are unmatched by ordinary natural rubber tires. Polyurethane solid tires have the following characteristics: Polyurethane solid tires are manufactured by casting process, and their structure is very different from the tires currently produced. A full polyurethane pneumatic tire is composed of three parts: the carcass, the belt layer and the tread. Among them, the carcass is made of polyurethane elastomer with higher modulus, which is relatively hard, so it has better fatigue resistance, dimensional stability and cutting resistance; the belt layer on the upper part of the carcass is made of aramid fiber wound in the circumferential direction Or steel cords, and the tread is cast from a low-modulus polyurethane elastomer to ensure the tire's wear resistance and ride performance.
