Abstract

The invention involves a spring for a floating caliper disc brake with a frame jaw caliper which, in the middle section of its axial outer edge, has a side window and on both sides of this window openings for an axial bracket of a fixed brake anchor plate. The caliper is displaceably and axially mounted on the bracket of the brake anchor plate. Brake linings are attached on both sides of the disc brake to the bracket of the brake anchor plate in an axial, displaceable manner and are also overlapped by the frame jaw caliper. The invention includes a onepiece curved wire holding spring, the middle section of which is releasably attached to the axial outer brake lining and which has two springs arms that are essentially placed in a contrary tangential direction to the middle section. The holding spring biases the frame jaw caliper radially against the brake anchor plate and biases the axial outer brake lining axially against the inside of the outer edge of the frame jaw caliper.

Dependent claims

A spring configuration for a floating-caliper disc brake with a fist-and-frame-type caliper which, in the central area of its axially outer fist-and-frame-type-caliper leg, comprises a leg window and apertures provided on both sides of this leg window for an axial carrier arm each of a brake carrier stationarily connected to the chassis and which is supported axially displaceably on the brake carrier, with brake pads being supported axially displaceably on the carrier arms of the brake carrier on both sides of the brake disc and moreover being straddled by the fist-and-frame-type caliper, comprising:

a retaining spring which includes a central section, detachably connected with the axially outer brake pad, and two spring arms projecting from the central section in opposite tangential directions wherein, said two spring arms secure the fist-and-frame-type caliper radially relative to the brake carrier and secure the axially outer brake pad axially relative to the inside of the outer fist-and-frame-type-caliper leg wherein the central section of the retaining spring has a central part which is bent in the shape of a hairpin and the legs of which reach behind an enlarged, axially tapering head of a pin disposed on the outer brake pad and axially projecting therefrom into the leg window and in that the central part is connected with axial tensile stress with a spring arm each spring arm supporting themselves axially on the outer fist-and-frame-type-caliper leg wherein the two legs of the hairpin-shaped central part each pass over into a second leg which is bent like a hairpin in the opposite direction and which passes over into a spring arm of the retaining spring via an axially extending portion.
