Technical Field
The utility model relates to an exempt from pneumatic tire equipment technical field, concretely relates to novel exempt from pneumatic tire.
Background
A tire is a ground-rolling circular ring-shaped elastic rubber article mounted on various vehicles or machines. The tires for electric vehicles and motorcycles, i.e. the tires applied to electric vehicles and motorcycles, are usually inflatable tires, and are developed into vacuum tires at present, and the tires have excellent performance, but have obvious defects, are easy to puncture and burst, and have low bearing capacity.
In order to avoid the phenomenon of tire burst, an inflation-free solid tire is introduced on the market, but when the tire is connected with a hub, the contact effect is poor, and the following points are mainly shown:
1. the connection effect of tire and wheel hub is poor, can appear the phenomenon of aversion, and the aversion also is the phenomenon that appears skidding between tire and the wheel hub, can cause serious potential safety hazard when the tire appears the aversion.
2. When turning round, because electric motor car motorcycle when turning round, the tire can incline, and traditional inflation-free tire height is higher can receive the ground to the reaction force of tire when turning round, leads to the tire to take off the circle easily, can cause very serious potential safety hazard equally.
3. The traditional solid tire has poor damping effect because the traditional solid tire adopts polyurethane as a foaming material, and the polyurethane foaming material has poor damping effect, so that the damping effect of the tire is poor.
Therefore, a novel non-pneumatic tire is provided.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
The utility model provides a not enough to prior art, the utility model provides a novel exempt from pneumatic tire, overcome the not enough of prior art, reasonable in design, compact structure has solved the easy tire burst of current pneumatic tire, and solid tyre is easy to be out of turn simultaneously, the poor problem of aversion and damping effect, the utility model discloses a rubber has improved the damping effect of tire through the good elastic property of rubber as the foaming material, has improved the connection effect of tire and rim simultaneously, prevents to shift, through the thickness that has reduced the casing, prevents to be out of turn to under the condition that reaches to prevent to blow out, improved the damping effect of tire and prevent to be out of turn and the effect of aversion, have very strong practicality.
(II) technical scheme
In order to achieve the above purpose, the utility model discloses a following technical scheme realizes:
a novel inflation-free tire comprises a tire and a hub, wherein the tire is sleeved on the hub, the tire comprises a tire body, a tire crown and a tire root, one side of the tire body, close to the hub, is connected with the tire root, the tire root is sleeved on a rim of the hub, the other end of the tire body is connected with the tire crown, the tire body, the tire crown and the tire root are mutually connected to form a closed structure, and a foaming tire core is arranged in the closed structure;
the tire is characterized in that annular grooves clamped with the rim are formed in the side walls of the two ends of the tire root, male carved patterns are arranged on the side walls of the annular grooves, and female carved patterns corresponding to the male carved patterns are arranged on the side walls of the rim.
Furthermore, the foaming tire core is made of rubber foaming materials.
Further, the thickness of the tire crown and the tire root is larger than that of the tire body.

2. The connecting effect of the tire and the wheel hub is improved, the friction force can be increased, and the slipping condition between the tire and the wheel hub is prevented. The diameter through setting up the rim slightly is greater than the diameter of child root, through the elasticity of rubber, cup joints the child root on the rim, simultaneously because the diameter of child root is less than the diameter of rim to make child root and rim contact inseparabler, prevent the knockover, provide frictional force simultaneously and prevent the condition that skids between tire and the wheel hub from appearing.
3. The height of the tire is reduced, and then the effect of preventing the knocking over is achieved. Thickness through setting up the child crown and adding the child root is greater than the thickness of casing, is different from traditional tire, and the thickness of casing is great, leads to the tire on the high side, appears the phenomenon of knocking over easily when turning round, and adopts the less tire of casing thickness, has reduced the height of tire, can reduce the ground when turning round to the reaction force of tire, prevents that tire and wheel hub break away from also the condition of just also knocking over.
4. The elasticity effect and the vibration damping effect of the tire are improved. Through adopting rubber as the foaming material, improve the elasticity of tire, the elasticity performance of rubber is higher, improves the elasticity of tire, can also set up the hole simultaneously for solid construction on the foaming child core simultaneously, can play certain damping effect through setting up the hole, through setting up solid construction, can improve the bearing capacity.
5. The friction force can be improved, and the slipping condition between the tire and the hub is prevented. The male carved patterns are arranged on the tire root, the female carved patterns corresponding to the male carved patterns are arranged on the rim, and the male carved patterns are in contact with the female carved patterns, so that the friction force is improved, and the phenomenon that the tire and the hub slip, namely the displacement, is prevented.
6. The foaming tire core replaces the traditional inflatable inner tire, so that the bearing capacity is improved, the puncture is prevented, and meanwhile, the effect of preventing tire burst can be achieved.
