The function of the brake caliper piston is to significantly increase the braking force; 2. The effect of slowing down, stopping, or maintaining a stopped state of moving wheels; 3. Press the brake shoes against the brake disc to produce a braking effect; 4. Prevent impurities from damaging the piston.
Research on the influence factors of the sealing groove structure on the return amount, required fluid volume, and drag torque of the caliper piston in the Qifeng caliper piston representation by Xu Shitang; Yi Gang; As a key structure in the design of brake caliper assemblies, the sealing groove structure has a significant impact on the basic performance of the caliper. The quality of its structural design directly affects the basic performance of the caliper itself, such as piston return, required fluid volume, and drag torque, and even affects the overall fuel consumption and brake pedal feel of the vehicle Based on different sealing groove structures, combined with CAE analysis and experimental verification, the influence of sealing groove structure on the return amount, required liquid volume, and drag torque of the caliper piston was demonstrated, which facilitates the selection of suitable groove types according to design goals in later design and has good engineering guidance significance |
