Abstract

A wheel brake device, which in particular is actuatable electromechanically, for a motor vehicle, includes a pivotable lever, one end of which is engaged by an energy-storing spring element and which with its other end presses against a wheel brake lining. The lever is pivotably supported by a support means that is displaceable in the longitudinal direction of the lever. By displacement of the support means in the longitudinal direction of the lever, a lever arm with which the energy-storing spring element engages the lever lengthens, and a lever arm with which the lever presses against the wheel brake lining shortens. A pressure force with which the energy-storing spring element, via the lever, presses the wheel brake lining against a brake disk can be adjusted by displacement of the support means.

Claims7

Dependent claims

A wheel brake device for a motor vehicle, having a wheel brake lining that for generating a braking moment can be pressed against a brake body connected to a vehicle wheel in a manner fixed against relative rotation, the wheel brake device (10) comprising

a pivotable lever (22), with which the wheel brake lining (18) can be pressed against the brake body (14) by pivoting of the lever (22);
an energy-storing spring element (26), which at a point spaced apart from the wheel brake lining (18) engaging and urging the lever (22) in the direction of pressing the wheel brake lining (18) against the brake body (14);
the lever (22) including a nonrectilinear sliding guide (30, 32) pivotally supporting the lever (22) on a support means (32, 34),
the support means (32,34) being displaceable in the longitudinal direction of the lever (22) and providing a fulcrum about which the lever (22) pivots;
and
a course of the sliding guide (30, 32) of the lever (22) being selected such that as the support means (32, 34) is displaced along the longitudinal direction of the lever (22), the course of the sliding guide (30, 32) extends at least approximately parallel to a displacement direction of the support means (32, 34).
