[0001] The utility model relates to the technical field of automobile accessories, in particular to a shockproof structure of an automobile brake wheel cylinder. Background Art
[0002] The car brake cylinder is an indispensable component of the braking system. Its main function is to push the brake pads, which are pushed outward and then rub against the rotating brake drum to reduce the vehicle speed and stop it. When the braking system is working, the master cylinder generates thrust after the driver in the cab steps on the brake to press the hydraulic oil into the cylinder through the pipeline. The piston inside the cylinder is subjected to the liquid pressure and starts to push the push rods on both sides to move and push the brake pads outward to brake. In order to reduce the vibration damage to the brake cylinder during operation, the shock-proof structure of the car brake cylinder is required.
[0003] However, the anti-vibration structure of the automobile brake cylinder is generally used to cushion and shockproof the external body of the cylinder during installation and use. However, since the rotating cylinder is directly fixed on the brake base plate, during the vehicle's driving, the vibration force will still be directly transmitted to the cylinder through the brake base plate installed on the axle, which can easily cause the internal components to move, affecting the braking accuracy of the cylinder, and the anti-vibration effect is insufficient, making it inconvenient to install the brake cylinder for shockproofing.
[0004] Now, a novel automobile brake cylinder shockproof structure is proposed to solve the above-mentioned shortcomings. Utility Model Content
