Abstract

The lining support plate (11) incoporates a widened lug part (16) which prolongs a neck part (15) round which is arranged the end loop (31) of the wire spring (30), of which the end of the strand portion (32) opposite the loop (32) has at least one transverse bent part (37) intended to be received in a central through-orifice (22) in the plate (11).

Claims

1. A friction-element assembly equipped with an anti-noise spring, the friction-element incorporating a lining-support plate intended to cooperate in anchoring and sliding engagement with dihedral guide surfaces of a torque support member of a disc brake by means of notches formed in the lateral edges of the support plate, the support plate incorporating, at a level of at least one of said notches, an aperture formed in an adjacent transverse edge for fitting of the anti-noise spring, said aperture and an adjacent one of said notches forming a neck prolongated outwardly by a widened lug part, the spring comprising an elastic wire and having an end part in the form of a closed loop engaged around the neck part to bear normally by means of a central part against a bearing zone of the aperture, the loop being prolongated by a strand portion provided at an end opposite the loop with means for fitting on a central zone of the lining support plate, characterized in that the lining support plate has, at a level of the central zone, a single through-orifice receiving therethrough a transversely bent end of said strand portion of said spring, the closed loop comprising an orthogonally bent end of the central part extending over and engaging the elastic wire and a radially inwardly bent nose portion at an end of said loop, the length of said strand portion being greater than a distance between said orifice and an adjacent end of said lug part limiting the aperture for the spring, and the length of said strand portion being less than a distance between the orifice and a bottom portion of said aperture delimiting said neck part laterally, the end of said strand portion opposite the loop forming the transversely bent end which is received in the orifice of the plate and extends to an orthogonally bent end portion located on a side of the support plate opposite a side along which said strand portion extends.

2. The assembly in accordance with claim 1, characterized in that, at rest, said orthogonally bent end portion is substantially coplanar with a side of said loop opposite said strand portion.
