A brake assembly suitable for hub motors

Abstract

The invention discloses a brake assembly suitable for hub motors, which is characterized in that it includes an inner buckle annular brake disc, a facing caliper and a hub motor housing, and the inner buckle annular brake disc has an inner brake The rotor, the outer brake disc and the connecting arm, the radially outer end of the inner brake disc and the radially outer end of the outer brake disc are connected through the connecting arm, the hub motor shell is connected with the outer brake disc, and the diameter of the opposing caliper There are lugs extending inward for connection with chassis components. The opposing caliper includes a first caliper body and a second caliper body. The first caliper body is arranged inside the inner brake disc, and the second caliper body is arranged on the inner brake disc In the cavity between the disc and the outer brake disc, the first caliper body is provided with the first piston and the first friction plate, the second caliper body is provided with the second piston and the second friction plate, the first piston and the second piston Opposed to the inner and outer sides of the inner brake disc, the second friction plate and the first friction plate cooperate with each other to clamp the inner brake disc for braking, maintaining the stability of the opposing caliper assembly during dynamic operation and braking .

Description

technical field [0001] The invention relates to a new energy vehicle brake, in particular to a brake assembly suitable for in-wheel motors. Background technique [0002] With the popularization of new energy vehicles, in-wheel motors are one of the important components in the development of new energy vehicles. The in-wheel motor is a motor assembly designed to integrate the power system, transmission system and braking system of the car. [0003] Since the wheel hub motor uses a traditional one-piece caliper, the two ends of the caliper body jaw are closed, so it cannot be installed from the inside of the brake disc. In the prior art, floating calipers are generally used, but there is a braking bias. Grinding, the thickness difference of the brake disc changes too fast, abnormal noise, overheating of the hub motor, etc. SUMMARY OF THE INVENTION [0004] In view of the technical problems existing in the background art, the technical problem solved by the present inventio...

Problems solved by technology

[0003] Since the wheel hub motor uses a traditional one-piece caliper, the two ends of the jaws of the caliper body are closed, so it cannot be installed from the inside of the brake disc. In the prior art, a floating caliper is generally used, but there is a brake bias Grinding, rapid change in the thickness difference of the brake disc, abnormal noise, overheating of the hub motor, etc.
