Abstract

The invention provides an automobile comprehensive parking brake caliper. The automobile comprehensive parking brake caliper comprises a caliper body assembly, a bracket assembly and a return spring, wherein the caliper body assembly is connected with the bracket assembly through flange bolts; the caliper body assembly is provided with two sub assemblies including a piston assembly and an actuator assembly, the actuator assembly and the piston assembly are correspondingly pressed and riveted through special automatic equipment, and it is ensured that all indicators meet the specifications and standards strictly. The piston assembly is assembled into a cylinder hole of a caliper body though screw-in type assembling of an adjusting nut and an adjusting screw rod, so that the reliability is ensured after the piston assembly is assembled into the cylinder hole of the caliper body, parking brake force, product quality and parking efficiency are improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of automobile braking, in particular to an automobile integrated parking brake caliper. Background technique [0002] The ball-disk integrated parking brake caliper based on the principle of ball ramp boosting is being adopted by more and more cars in my country, replacing the traditional dribbling drum parking brake caliper and lever integrated parking brake caliper. trend is becoming more and more obvious. The existing application publication number CN 104712689 A and the patent application number 2015100932960 disclose a disc brake cylinder assembly and a brake caliper with a parking mechanism. Although this patent has the characteristics of low cost, the screw rod and the screw sleeve are multi-headed. The displacement of the piston cannot be accurately calculated due to the right-handed thread fit. The parking action shaft and fittings are assembled in pieces. The cylinder is positioned by a retaining r...
