What are the differences between pneumatic tires and rubber solid tires?

Tires play an important role in the driving of the scooter, which affects the comfort, safety, power consumption and many other performances of the scooter. At present, the common scooters on the market usually use two types of tires-tubeless tires & solid tires. Which tire is better?Tubeless tire: people usually refer to tubeless tire as "tubeless tire". A self-adhesive layer made of a special mixture of unvulcanized rubber, using the inner wall of the tire and the inner layer of the bead to ensure good air tightness between the tire and the rim, thus replacing the role of the traditional inner tube, the outer tire also plays the role of the inner tube , and after the tire is inflated, the toe is tightly combined with the rim, effectively avoiding deflation.There are many advantages of tubeless tires1. Wear-resistantTubeless tires are wear-resistant and have better dynamic balance performance, and the driving comfort can also be improved, so they are more suitable for long-distance high-speed driving for a long time.2. Good heat dissipationThe tubeless tire has no inner tube and pad belt, which effectively reduces the heat generated by friction between the inner tube of the tire and the inner cavity of the tire. The air inside is in direct contact with the rim, and the heat can also be dissipated directly through the rim, so that the tire temperature will not be too high Phenomenon, prolong tire service life.Solid tire: Rubber solid tire is a kind of tire corresponding to pneumatic tire (hollow tire). Its carcass is solid, without cord as skeleton, without inflation, without inner tube or airtight layer. Solid tires are suitable for vehicles traveling at low speeds.There are many advantages of rubber solid tires1. Safe and secureBecause the solid tire carcass is made of all rubber, the puncture resistance of the tire is guaranteed to the greatest extent. The solid tire has small deformation and good running stability. Because of its puncture and tear resistance, it does not need to be inflated, which avoids the heavy labor of frequent tire repair and replacement.2. Long lifeThe service life of solid tires is generally 3-5 years, which can be well adapted to many harsh environments3. EconomyCompared with pneumatic tires, solid rubber tires are less prone to punctures or punctures, so they are more economicalAt the same time, solid tires are suitable for all kinds of low-speed vehicles. Even if the tires are punctured during driving, the elderly don’t have to worry about the vehicle rolling over due to a puncture, or they are in a hurry because they cannot find a place to repair the tire.

What are the reasons for forklifts to be equipped with solid tires?

We all know that the forklift tire is an important part of the forklift. It supports the full weight of the vehicle, bears the load of the forklift, and transmits forces and moments in other directions. It transmits the torque of traction and braking, and ensures good adhesion between the wheels and the road surface, so as to improve the power, braking and passing of the forklift. But do you know why you need solid tires for forklifts?1. Excellent safety performance, which is conducive to improving work efficiencyConsidering that the solid tires are all made of rubber, the puncture resistance of the tires is guaranteed to the greatest extent, and the hidden danger of tire punctures during the load-bearing operation of industrial vehicles and in harsh working environments is fundamentally eliminated. Solid tires have small load-deformation and good running stability. Because of their wear resistance and no need to inflate, they avoid the heavy labor of frequent tire repairs and tire replacements, which can improve the utilization rate and work efficiency of vehicles, and run vehicles at low speeds and efficiently. In China, solid tires can completely replace pneumatic tires.2. Reasonable structural design to ensure good performance of tiresThe solid tire adopts an advanced three-stage structure design, and the three kinds of rubber materials respectively ensure the overall performance of the tire. The high-rigidity, high-strength base rubber and steel ring support not only ensure the stiffness of the tire, but also ensure the tightness of the tire and the rim, which fundamentally eliminates the problem of the sliding ring of the solid tire; the high-elasticity intermediate rubber effectively It absorbs the vibration generated when the vehicle is running, has a comfortable ride, and avoids damage to the vehicle at the same time; the thickened tread rubber layer ensures the tear and wear resistance of the tire and improves the service life of the solid tire.3. Advanced technology and formula designThe production of solid tires has advanced technology with more than half a century of production history and experience. The design of rubber formulations maximizes the performance of tires.

Introduction to the knowledge of anti-skid of solid tires?

The solid tire improves the heat generation function of the tire, so that the heat generation of the tire is greatly reduced. The solid tire and the rim are press-fitted together through an interference fit. The excessive heat generation of the carcass will cause the tire slip ring to expand.Ordinary tires and all-season tires are wear-resistant, but in winter, especially below zero degrees Celsius, the traction of the tires will be relatively reduced, and there will be slippage in the face of icy and snowy roads. The rubber composition is higher and not wear-resistant.Solid tires have the advantages of good rigidity, high hardness, good stiffness, small deformation, small expansion coefficient, and low heat generation, so the slip ring phenomenon caused by the expansion of the hub caused by the heat generation of the tire is basically eliminated. A tire anti-skid ring is a tire anti-skid device provided for cars driving on ice and snow roads.It utilizes the protruding tufts of the tread and the circular dimples on the tread, which greatly improves the grip between the tire and the ground, and has the characteristics of good anti-skid effect, no damage to the road surface, convenient installation and use, low cost and simple structure.In addition to more protection work in vehicle design and configuration, careful operation is the key to preventing slippage when encountering special road conditions. Solid tires on slippery roads should be controlled more gently, always alert to possible accidents and emergencies ahead. When driving on the road in the rain, your shoes can get wet and easily slip off the pedals when you step on them. The soles of the shoes should be dried on the car carpet before starting the engine, and all car drivers should regularly check that the headlights, taillights, brake lights, and turn signals are in normal condition.

What is the difference between solid tires and pneumatic tires?

The solid tire is a kind of tire corresponding to the pneumatic tire (hollow tire). The earliest tires are solid tires. Solid tires are currently only used for high-load vehicles or machinery that travel at low speeds, and are also used for fixed-position machinery.Solid tires are generally divided into two types: bonded and non-bonded. The former refers to tires whose rubber is directly vulcanized on the rim, and the latter refers to tires that are vulcanized and then fixed on the rim. According to the shape, it is divided into cylindrical solid tire and inclined bottom solid tire; according to the application, it is divided into antistatic, conductive, oil-resistant, high-load solid tire, and environmentally friendly non-marking solid tire.Solid tires are generally used under high load, and the rubber compound is required to have sufficient pressure resistance and wear resistance, high enough tensile stress, high hardness, low permanent deformation and good wear resistance.Solid tire is an industrial tire suitable for running vehicles under low-speed and high-load harsh conditions. Its safety, durability and economy are obviously superior to pneumatic tires, and are widely used in various industrial vehicles, military vehicles, construction machinery. , towed vehicles in ports and airports, etc.

Is the performance of solid tires affected by temperature?

Is the performance of solid tires affected by temperature?In fact, the influence of the outside air temperature on the working temperature in the tire is very small, because when the vehicle is running normally, the air temperature inside the tire will increase significantly, and the influence is much greater than that of the outside temperature.If your car is equipped with tire pressure monitoring, you might as well verify it yourself. Next time you drive, pay attention to observe the changes in tire pressure. You will find that even on a hot day, from a cold car to driving for a long time, the tire pressure is very high. There will be no particularly noticeable changes.There are also studies that show that when the tire temperature changes by 50 degrees Celsius, the tire pressure change is only 0.5bar, while the safe tire pressure value of our car is generally 2.2bar-2.8bar, so as long as we follow the standard tires on the door frame Pressure to operate, a change of 0.5bar will not let it exceed the safe value at all.The temperature of the tire will increase after a period of driving, and the temperature of the tire is higher than the ambient temperature, so the influence of the ambient temperature on the tire pressure can be ignored. That is to say, the tire pressure in the hot tire state will not be affected by the seasonal ambient temperature. That is, the tire pressure in the working state will not be affected by the seasonal ambient temperature.However, it should be noted that the problem of tire temperature is undoubtedly a fatal weakness for long-distance bus drivers and large truck drivers. Long-distance driving will accelerate the wear of tires, and excessive temperature will accelerate the aging of tire rubber and the softening of steel wires. Overheating will be directly fed back to the tread surface, which is the pattern. The pattern will speed up the wear, but a good tire has a strong ability to dissipate heat. Therefore, when the temperature is high, the quality of the tire rubber can be tested, and the material of the pattern is the tire rubber.
