Disc brake

摘要

A disc brake provided with a guide spring capable of preventing a vibration of a pad plate having a friction pad mounted thereon, and capable of separating the friction pad from a disc in a rapid manner after a braking operation is finished, the disc brake including a disc rotating together with a wheel of a vehicle, two pad plates disposed at both lateral sides of the disc, respectively, to perform a braking by pressing both lateral side surfaces of the disc and each having a friction pad, a caliper housing and a piston that are configured to press the pad plate, and a guide spring enabling the pad plates to operate as an integral body and absorb shock.

1. A disc brake having a disc rotating together with a wheel of a vehicle, two pad plates disposed at both lateral sides of the disc, respectively, to perform a braking by pressing both lateral side surfaces of the disc and each having a friction pad, and a caliper housing and a piston that are configured to press the pad plate, the disc brake comprising:
a protrusion unit protruding from two end portions of an outer side of the caliper housing, a coupling unit protruding from two end portions of each of the pad plates, and a guide spring formed in a bent manner to surround the protrusion unit and the coupling unit, wherein the guide spring extends from a coupling unit of one of the pad plates to a coupling unit of the other one of the pad plates along a first path, and extends from the coupling unit of the other one of the pad plates back to the coupling unit of the one of the pad plates along a second path different from the first path.
