The invention provides a brake wedge-shaped piston, a design method of the brake wedge-shaped piston, a common brake cylinder, a parking brake cylinder and a three-point type and four-point type hanging clamp unit. The brake wedge-shaped piston comprises a disc body structure and a wedge block structure, wherein the wedge block structure is connected with one end of the disc body structure, the wedge block structure has a wedge-shaped surface and a vertical surface, the wedge-shaped surface comprises a driving inclined surface section and an avoiding concave part which are adjacently arranged, the driving inclined surface section is positioned between the disc body structure and the avoiding concave part, the avoiding concave part is arranged close to the vertical surface relative to the driving inclined surface section, and the slope of the avoiding concave part is different from that of the driving inclined surface section. The problems that in the prior art, a wedge-shaped piston of a braking part is unreasonable in structure, the braking performance of a braking device is poor, and the personal safety of passengers cannot be guaranteed are solved.
Description
technical field [0001] The invention relates to the technical field of vehicle braking, in particular to a brake wedge piston and a design method thereof, a common brake cylinder, a parking brake cylinder and a three-point and four-point suspension clamp unit. Background technique [0002] The vehicle brake caliper unit mainly includes two parts: a brake cylinder and a brake caliper. In order to increase the braking force, some brake cylinders also include a brake force amplification mechanism, which is usually installed in the installation cavity of the brake cylinder. A kind of brake force amplifying mechanism comprises a brake arm and a wedge-shaped piston for driving the brake arm to move telescopically in the installation cavity, and the end of the brake arm away from the wedge-shaped piston is connected with the clamp part (ie lever) of the brake caliper. In this way, during the braking process of the vehicle, the brake arm drives the other end of the clamp part (that ...
