A self-adjusting hydraulic brake caliper assembly

Abstract

The invention discloses a self-adjusting type hydraulic brake caliper assembly. The self-adjusting type hydraulic brake caliper assembly comprises a caliper body, a static friction plate and a dynamic friction plate opposite to the static friction plate are arranged in the caliper body, and the dynamic friction plate is connected with the outer side of a piston movably arranged in the caliper body. A pin shaft, a shaft sleeve and a compression spring are further included. The shaft sleeve is arranged on the caliper body, one end of the pin shaft is connected with the shaft sleeve through the compression spring, and the other end of the pin shaft matches an inclined ratchet arranged on the piston. The ratchet outside a piston body matches the pin shaft with the compression spring to form a self-adjusting mechanism, the piston is controlled to reset, and it is guaranteed that the piston is within the required range always. The aim of automatically adjusting the clearance between the static friction plate and the dynamic friction plate is achieved, the brake distance is controlled, and the brake effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of brake caliper, in particular to a self-adjusting hydraulic brake caliper assembly. Background technique [0002] At present, there are two main types of suspension hydraulic brake calipers used in agricultural machinery equipment: one is to control the piston travel distance through a rectangular ring, so as to achieve the purpose of self-adjustment. The advantage of this brake caliper is that it can automatically ensure two The gap between the brake pad and the friction disc, but because the braking and return stroke of the rectangular ring is too small and the end face of the brake disc itself has a large jump, the brake pad is always close to the brake disc, so that the friction of the friction disc The temperature rises sharply and burns, which obviously reduces the service life and braking efficiency of the friction plate; the other is to forcibly pull the piston brake plate back by the external forc...

[0002] At present, there are two main types of suspension hydraulic brake calipers used in agricultural machinery equipment: one is to control the piston travel distance through a rectangular ring, so as to achieve the purpose of self-adjustment. The advantage of this brake caliper is that it can automatically ensure two The gap between the brake pad and the friction disc, but because the braking and return stroke of the rectangular ring is too small and the end face of the brake disc itself has a large jump, the brake pad is always close to the brake disc, so that the friction of the friction disc The temperature rises sharply and burns, which obviously reduces the service life and braking efficiency of the friction plate; the other is to forcibly pull the piston brake plate back by the external force of the spring, and the piston is pulled back to the same original position every time. The advantage of the moving caliper is to make up for the defects of the former brake caliper, but with the wear of the brake pads, the braking gap increases continuously, the braking effect decreases or fails, and the braking distance becomes larger or lost
