Spring-Equipped Member for Guiding a Disc Brake Pad and Disc Brake provided with such Guiding Members

摘要

A brake calliper has two arms, each including a housing and a stub. A member for guiding a disc brake pad is disposed in the housing, and is secured by lugs to a front of the stub. The member includes a body having a U-shaped section formed by an inner radial surface, a base, an outer radial surface, and includes a tongue that extends beyond an edge of the body, and that is configured to be hooked in the housing and to fully lock the member in the arm. An inner side of the body is bordered by an inner front supporting surface disposed against an inner surface of the arm. An outer front supporting surface is disposed against the front of the stud, extends into a hairpin damper spring extending towards the front of the stud, and is bordered on each side by a tongue that form side end-stops.

主权项

1. A guiding member for a disk brake pad in a cap that has two U-like arms connected by two bars, each arm having at respective two ends thereof an axial housing which has a substantially rectangular cross-section and which is bounded by a base, an internal radial surface an external radial surface, and a stud, the guiding member comprising:
a body which has a substantially U-shaped cross section that is substantially rectangular, such that the body is configured to be positioned in the axial housing; an external radial surface configured to abut the upper surface of the axial housing; a base configured to abut the base of the axial housing; an internal radial surface that includes a locking tongue configured to press against and engage the lower surface of the axial housing; a front external abutment surface configured to abut a front surface of the stud, and which includes:
two tongues that form lateral stops extending from each side of the stud; anda hairpin-like shock-absorbing spring that is configured to move towards the front of the stud so as to resiliently press against a side of the disk brake pad above a lug of the disk brake pad; and a front internal abutment surface configured to abut the front internal surface of the arm, and which is configured to receive a face of the disc brake pad below the lug; wherein the guiding member is formed by a folded spring steel band that is configured to be fixed to the stud and positioned in the axial housing of the arm; wherein the guiding member is further configured to receive the lug in an axially sliding manner; and wherein the lug includes a radial spring configured to guide and press the guiding member into the axial housing.
