Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tires, in particular to a cushion rubber composite for improving tire shoulder voids. Background Art
[0002] A tire is one of the most important components of an automobile, and its functions mainly include: supporting the entire weight of the vehicle and bearing the load of the automobile; transmitting the torque of traction and braking to ensure the adhesion between the wheel and the road surface; reducing and absorbing the vibration and impact force when the automobile is running, preventing the automobile parts from being severely vibrated and damaged early, adapting to the high-speed performance of the vehicle and reducing the noise during driving, and ensuring the driving safety, handling stability, comfort and energy-saving economy.
[0003] In the existing tire structure, the shoulder cushion rubber directly contacts the belt layer. The viscosity and modulus at 100% elongation of the shoulder cushion rubber are relatively low, and delamination between the belt layer and the shoulder cushion rubber is likely to occur during use. Therefore, a cushion rubber composite for improving tire shoulder voids is needed to meet the requirements. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a cushion rubber composite for improving tire shoulder voids to solve the problems raised in the above background art.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A cushion rubber composite for improving tire shoulder voids, including an airtight layer, a carcass, a belt layer, a shoulder cushion rubber, a tread, a sidewall, a shoulder cushion rubber type rubber and a film. The carcass is arranged on the airtight layer, the belt layer is arranged on the carcass and located at the top part of the carcass, the shoulder cushion rubber is arranged on the carcass and located at the side part of the carcass, the tread is arranged on the belt layer and the shoulder cushion rubber, the sidewall is arranged at the side part of the tread and also arranged at the side part of the carcass, the shoulder cushion rubber type rubber is arranged at the connecting part between the belt layer and the shoulder cushion rubber, and the film is arranged on the shoulder cushion rubber type rubber and located at the connecting part between the belt layer and the shoulder cushion rubber type rubber.
[0006] Preferably, the material of the film is similar to that of the belt layer.
[0007] The beneficial effect of the utility model is:
[0008] In the utility model, by adding the design of the shoulder cushion rubber type rubber and the film on the basis of the existing shoulder cushion rubber, the adhesion and stiffness transition between the shoulder cushion rubber and the belt layer are effectively improved, and the probability of delamination at the tire shoulder is reduced.
[0009] In the present utility model, by changing the design method of the cushion rubber composite part, the traditional cushion rubber composite part design is improved into a design of pasting a film on the shoulder cushion rubber type rubber, which is more convenient to operate, and the thickness, width, and position can be adjusted according to needs to be suitable for the use of tires of different sizes and specifications.
