Abstract

The invention provides a parking brake clamp and an automobile, and belongs to the technical field of motor vehicle braking. A clamp body, a piston arranged in the clamp body, a return spring base arranged in the clamp body and a screw are included, wherein one end of the screw is arranged in the piston, and the other end of the screw penetrates through the return spring base. The screw is sleevedwith a screw gasket. The screw gasket is located at the end, away from the piston, of the return spring base. When the screw drives the return spring base to move, the outer edge of the screw gasketabuts against the inner edge of the return spring base in the radial direction of the screw, so that the return spring base is clamped in the clamp body. When the piston is pushed out, the screw drives the return spring base and the screw gasket to move, the outer edge of the screw gasket abuts against the inner edge of the return spring base in the radial direction of the screw, the screw gasketis clamped at the end portion in the return spring base, pulling disengaging of the return spring base is avoided, reliability of the brake clamp during driving braking and parking braking is guaranteed, and parking safety is improved.

Description

technical field [0001] The invention relates to the technical field of motor vehicle braking, in particular to a parking brake caliper and an automobile. Background technique [0002] The parking function of the rear disc brake of a motor vehicle is divided into a mechanical parking structure and an electronic parking structure. The mechanical parking structure is divided into a cam push rod type and a ball disc type parking. The existing cam push rod type parking brake caliper As shown in CN206072182U, under the condition of high brake hydraulic pressure, when the piston can be pushed out due to the deformation of the brake caliper or the large space outside the piston of the brake caliper, the screw rod in the brake caliper drives the return spring seat to move, which will Pulling the return spring seat out of the caliper is called pulling off. The failure of the return spring seat to pull off will lead to safety problems such as brake oil leakage and parking failure. C...
