Title:
DISC BRAKE
Document Type and Number:
WIPO Patent Application WO/2021/215157
Kind Code:
A1
Abstract:
This disc brake comprises: a carrier having a fixed part fixed to a non-rotating part of a vehicle; a caliper that is attached to the carrier and has a cylinder part that accommodates a piston applying pressure to an inner brake pad; and a drive mechanism that has an electric motor and a reduction mechanism and transmits the driving force of the electric motor to the piston via the reduction mechanism, wherein the fastening direction of the fixed part with the non-rotating part of a vehicle is parallel to the direction orthogonal to the axial direction of the piston. As a result, although the electric motor, reduction mechanism, etc. are provided, the carrier can be miniaturized, and by obtaining high rigidity, the responsiveness at the time of braking, etc. can be improved.
