Abstract:

An arrangement for mounting a wheel axle and associated disc brake on a strut, particularly for use at the steerable front wheels of a motor vehicle with a front wheel drive, includes a first and a second component which are separatably connected to one another in the assembled condition of the mounting arrangement. The first component is secured to the strut and has a cup-shaped configuration. The second component has a central sleeve-shaped portion which abounds a passage in which the wheel axle is supported by a bearing interposed between the wheel axle and the sleeve-shaped portion. The second component also has two support arms which brake shoes of the disc brake are guided for movement toward and away from a disc rotor which rotates with the wheel axle. Two elongated guiding elements are secured to the second component, and a brake caliper is guided thereon for movement parallel to the axial direction of the wheel axle. The caliper carries a cylinder-and-piston unit of the disc brake, which includes a piston that directly acts on the brake shoe close to it, and a cylinder which transmits a reaction force via a bridge portion of the caliper to the other brake shoe.

Abstract:

A sealing element for a cylinder-and-piston unit, especially a dust boot of a disc-brake actuating unit, includes an annular deformable portion of an elastically deformable material, and an annular connecting portion of a resilient material which is permanently sealingly connected to the inner region of the deformable portion and mounts the same on a protruding annular portion of the piston which extends out of the cylinder, by clampingly engaging such protruding portion. The connecting portion is substantially U-shaped in axial section and includes an outer ring, an inner ring and an interconnecting web extending between the outer and inner rings. The inner ring converges in the direction of introduction thereof into the annular protruding portion of the piston and carries oppositely and outwardly oriented lugs which engage behind an internal bead of the protruding portion of the piston. A brake shoe has a clip with several prongs which engage behind the inner ring of the connecting portion. The inner region of the deformable portion may have a zone which is squeezed between the outer ring of the connecting portion of the sealing element and the external surface of the protruding portion of the piston to frictionally engage the latter.
