An automobile disc brake

Abstract

The invention discloses an automobile disc brake, comprising a brake disc and a brake caliper body, characterized in that the brake disc is connected to the axle bracket through a flange, and the brake caliper body comprises a first piston cylinder body and a second piston cylinder, the first piston cylinder and the second piston cylinder are installed inside the brake disc, and the second piston cylinder is installed at the front end of the first piston cylinder , the first brake pad and the second brake pad are respectively installed between the first piston cylinder, the second piston cylinder and the brake disc, and the first brake pad and the second brake pad are respectively fixed on the On the side of the first piston cylinder and the second piston cylinder, through the automobile disc brake, the outstanding problems in the later maintenance are improved, and the problem of the piston falling out caused by not stepping on the brakes during maintenance is prevented. The new brake pads are used to improve It improves the durability of the brake pads, greatly increases the service life of the brake pads, and reduces accidents caused by brake problems.

Description

technical field [0001] The invention belongs to the field of brakes, in particular to an automobile disc brake. Background technique [0002] In the post-maintenance of the vehicle, it is essential to replace the brake pads after the vehicle has driven to a certain mileage. This is related to the safety of the drivers and passengers. Every year, people have accidents due to brake problems, especially the durability of the brake pads. The problem needs to be improved urgently, and in order to prevent the piston from falling out when replacing the brake pads in the later maintenance process, it is also necessary to carry out the protection design during the later maintenance, but there is no design for this aspect yet, although the patent No. : CN200910306757.2 has announced the brake that is provided with auxiliary piston, has improved the stability of braking; Reduced the wearing and tearing of seal ring and oil chamber; Owing to reduced the weight of piston, thereby improve...

Problems solved by technology

[0002] In the post-maintenance of the vehicle, it is essential to replace the brake pads after the vehicle has driven to a certain mileage. This is related to the safety of the drivers and passengers. Every year, people have accidents due to brake problems, especially the durability of the brake pads. The problem needs to be improved urgently, and in order to prevent the piston from falling out when replacing the brake pads in the later maintenance process, it is also necessary to carry out a protective design during later maintenance, but there is no design for this aspect yet, although the patent No. : CN200910306757.2 announces the brake that is provided with sub-piston, improves the stability of braking; reduces the wearing and tearing of seal ring and oil cavity; Owing to reduced the weight of piston, thereby improves the return performance of piston, but does not mention Piston disengagement problem during later maintenance

[0003] Patent No.: CN201520632570.2 is a double caliper disc brake. However, when the brake pads are replaced in the later stage of the double caliper disc brake, the protection piston is not reflected. During the replacement process, sometimes do not step on the brake pedal to make the brake piston If it comes out, the brake fluid will leak, the installation process will be difficult, the driver will lose money, and the installation time will be prolonged.
