Technical Field

The invention relates to the field of brake calipers, in particular to a brake caliper which is used for a hub motor and is convenient for replacing a friction plate.

Background

As is known, a friction lining for a motor vehicle is a part which is also replaced during the normal service life of the vehicle. The existing brake caliper mainly comprises a caliper body, a shaft pin and a support, a cylinder hole for placing a piston is formed in the caliper body, the caliper body is connected with the support through the shaft pin, a spring leaf provided with a friction plate is arranged on the support, the opening direction of the caliper body and the opening direction of the support are outward in the radial direction of a brake disc, a brake caliper assembly can be reversely installed on an annular brake disc special for a hub motor, the friction plate slides by depending on the support of the spring leaf and is used for applying a braking force from an inner ring of the brake disc, and the. The existing scheme can be replaced if the friction plate needs to be replaced and the caliper assembly needs to be integrally disassembled, and due to the limitation of a suspension structure, the caliper assembly can be disassembled only by disassembling the whole hub motor angle assembly after the whole vehicle is assembled, and a plurality of wire harnesses are arranged on a motor, so that the friction plate is replaced very difficultly.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provide the brake caliper for the hub motor, which is convenient for replacing a friction plate.

The purpose of the invention is achieved by the following technical scheme: the brake caliper for the hub motor is convenient for replacing friction plates, and mainly comprises a caliper body, a piston, a rectangular sealing ring, a piston dust cover, an inner friction plate, an outer friction plate, a support, a shaft pin sleeve end cover, a shaft pin sleeve, a shaft pin, a spring piece, an air release screw cover and an air release screw, wherein the piston is installed in a cylinder hole in the caliper body in a matched mode, the rectangular sealing ring and the piston dust cover are arranged between the piston and the caliper body, the caliper body is connected with the support through shaft pins on two sides, the shaft pin sleeve is sleeved on the outer diameter of the shaft pin, the shaft pin sleeve end cover is installed at the top of the shaft pin sleeve, the inner friction plate and the outer friction plate are arranged on the support, the inner friction plate and the outer.

The opening directions of the clamp body and the support are the radial direction of the brake disc.

The invention has the beneficial effects that: the invention relates to a floating caliper disc brake assembly structure for a hub motor, which realizes the dismounting and replacement of friction plates under the condition of not dismounting a hub motor angle assembly and a circular brake disc, solves the difficulty of the replacement of the friction plates and has important significance for the mass production of the hub motor.
