Description

[0001] BRAKE PAD ASSEMBLY FOR PREVENTING UNEVEN WEAR [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a brake pad assembly for preventing uneven wear, and more particularly, to a brake pad assembly for preventing uneven wear of a pad assembly by reducing the behavior of a leading portion of an inner pad assembly and a trailing portion of an outer pad assembly.

Generally, a brake system is classified into a main brake used mainly for driving and a parking brake used for parking the automobile. Further, the main brake has a hydraulic type brake for braking through the hydraulic pressure generated by the operation of the brake pedal, and the hydraulic type brake is provided with hydraulic brakes for pressing the brake pads by hydraulic pressure on both sides of the disk rotated together with the wheels There is a disc brake.

Typical disc brakes are roughly divided into a housing in which a piston is installed and a carrier in which an assembly of brake pads and back plates (i.e., a pad assembly) is mounted and fixed to the vehicle body. In addition, the housing is provided with a piston which moves back and forth by hydraulic pressure inside a cylinder in which an inlet is formed.

When the brake pedal is depressed in a state in which the vehicle is running, hydraulic brake pressure acts on the master cylinder, and the hydraulic brake is continuously transmitted to the cylinder through the inlet. Therefore, as the piston advances by this hydraulic pressure, the leading end of the piston pushes the inner back plate toward the disc side, and the inner brake pad attached thereto presses the disc momentarily.

When the disc is braked by the brake pads (inner and outer) operated by the pistons in such disc brakes, the behavior of the leading portion of the inner pad assembly and the trailing portion of the outer pad assembly is relatively large. Accordingly, there has been a problem that the trailing portion of the inner pad assembly and the leading portion of the outer pad assembly are unevenly worn.

Further, the brakes of most medium-sized commercial vehicles have a structure in which a return spring presses the pad assembly at the upper end to reduce the behavior of the pad assembly. However, since the return spring does not support the pad assembly, the pad assembly easily moves, thereby causing a rattle noise due to contact between the pad assembly and the surrounding components.
