Abstract

The invention discloses a novel floating caliper disc brake which comprises a brake disc and a brake caliper. The brake caliper on the right side of the brake disc is provided with a piston chamber and a shaft hole, and an electric push rod passes through the shaft hole. A smart encoder that precisely controls the stroke of the electric push rod is mounted on the electric push rod. According to the scheme, a mode of driving a piston by the electric push rod is adopted, and the problem of sealing and oil leakage of a traditional brake does not occur. At the same time, the smart encoder on the electric push rod can accurately control the displacement of a movable brake block and avoid the excessive friction between the movable brake block and the brake disc. After a long period of work, wearoccurs on the surface of the brake disc, and the smart encoder can also well control the displacement of the movable brake block to continue braking. In addition, both sides of the movable brake block and a fixed brake block are provided with damping pieces, the braking vibration and noise can be effectively reduced during braking, and thus the brake according to the scheme is simple in structureand high in reliability.

Description

technical field [0001] The invention relates to a disc brake, in particular to a novel floating caliper disc brake. Background technique [0002] Disc brakes are an important part of braking system devices and are widely used in rail transit, aerospace, wind power generators and other fields. Floating caliper disc brake is a kind of disc brake. The rotating element in the friction pair is a metal disc that works on the end face, called the brake disc. The fixed element is composed of a small friction block and its metal back plate. Brake pads, these brake pad machine actuation devices are housed in clamp-shaped brackets across the sides of the brake disc, called brake calipers, the brake calipers are floating and can be axially relative to the brake disc move. The floating caliper and disc make up a floating caliper disc brake. [0003] Hydraulic disc brakes rely on the action of high-pressure brake fluid to push the piston, and a large amount of oil is injected during wo...
