Problems solved by technology

However, the current disc brakes use the elasticity and quantitative deformation of the piston sealing ring to return the piston and self-adjust the gap. The requirements for the elasticity, heat resistance, wear resistance and surface roughness of the piston sealing ring are very high, and it cannot be completely Guaranteed braking performance

Abstract

The invention relates to a disc brake caliper, and belongsto the field of a vehicle brake system. The disc brake caliper ischaracterized bycomprising a brake caliper (1), a brake caliper bracket (2),a sliding shaft (3), a main sliding shaft (30), an auxiliary sliding shaft (31), a sliding shaft bolt (32), a sliding shaft dustproof cover (33) and a hydraulic cylinder (4); the hydraulic cylinder (4) comprises a hydraulic cylinder body (40), a piston (21), a piston sealing ring (42), a piston dustproof ring (43), a guide ring (44), a wearing ring (45), a return spring (46), a stop spring (5) anda friction block assembly (6). The disc brake caliper provided by the invention adopts a structure that the piston sealing ring is combined with the guide ring and the wearing ring, so that the guidefunction is additionally achieved, and the service life of the piston sealing ring is prolonged; meanwhile, the accurate returning of the piston can be ensured by adopting the piston with the structure of the wearing ring and the guide ring; and then the gap can be adjusted automatically.

Description

technical field [0001] The present application relates to the field of vehicle braking systems, in particular to a disc brake caliper. Background technique [0002] A brake is a component that generates a braking torque, a force that resists a vehicle's movement or tendency to move. At present, friction brakes are mostly used in automobiles, which use the friction between the fixed element and the working surface of the rotating element to generate braking torque. [0003] The calipers of floating caliper disc brakes are generally designed to slide axially relative to the brake disc. Wherein only the inner side of the brake disc is provided with a hydraulic cylinder, while the outer brake block is attached to the caliper body. [0004] When braking, the piston pushes the movable brake block to the brake disc under the action of hydraulic pressure. At the same time, the reaction force acting on the brake caliper body pushes the brake caliper body to move rightward along th...
