Disc brake pad
A disc brake pad includes lugs, each of which is provided with a groove that receives the tongue of a coiled spring disposed in a housing in the brake yoke. The aforementioned groove has an essentially mixtilinear rectangular section, of which the base is formed in cross-section by a central portion in the form of a convex root face forming a support extending on each side into a fillet recessed from the supporting plane. The fillet joins the respective side of the groove behind the supporting plane.
1. A disk brake pad comprising:
a plurality of lugs, each of which includes an outer face in which a groove is defined, the groove extending in a longitudinal direction generally parallel to the outer face, the groove being configured to receive a tongue of a wound spring that extends into a housing in a brake cover,
wherein each lug of the plurality of lugs, in a plane perpendicular to the longitudinal direction, has a mixtilinear generally rectangular cross-section defining the groove, the groove being defined by a base including a protruding central portion forming an abutment and defining an abutment plane parallel to the outer face, the base extending from each side of the protruding central portion to a fillet, which is recessed from the abutment plane and connects the base to a respective side of the groove at a position behind the abutment plane relative to the outer face.
2. The brake pad as claimed in claim 1 , wherein a first end of the groove in the longitudinal direction is an open end and a second opposite end is a closed end.
3. The brake pad as claimed in claim 1 , wherein the protruding central portion protrudes in a direction towards the outer face.
4. The brake pad as claimed in claim 1 , wherein each fillet is recessed from the abutment plane in a direction away from the outer face.
5. The brake pad as claimed in claim 1 , further comprising:
a generally planar brake plate defining a brake plate plane,
wherein the outer face of each lug of the plurality of lugs is parallel to the brake plate plane.
6. The brake pad as claimed in claim 5 , wherein:
the generally planar brake plate comprises a first end and a second end, and
a first lug of the plurality of lugs extends away from the first end and a second lug of the plurality of lugs extends away from the second end.
