Novel floating caliper disc brake

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
