Abstract

A multidisc brake (1) for a motor vehicle has two multidisc devices (7, 8) and an actuating device (9) for brake-actuating and/or brake-releasing operation of the multidisc devices (7, 8) and has an electric drive (16) for the translational actuation (spreading) of the actuating device, in particular of the ramp unit (9). In the case of a spreading operation, the multidisc devices (7, 8) are preloaded in a metered manner by the actuating device and generate desired frictional engagement, and correspondingly reversed control of the actuating device allows a correspondingly metered brake release. By means of the electric drive (16), the action of the multidisc brake (1) can be metered overall in a particularly accurate, sensitive and compensated manner in modern vehicle topology taking into consideration all peripheral brake components and systems, including recuperation.

Abstract

The invention relates to a spreader unit (2) for a drum brake (1), which spreader unit has an adjustment device (26), which ensures that the clearance remains substantially constant even in the event of wear of the brake pads (5). The adjustment device (26) is designed in such a way that, in the event of increased actuation travel distance of the spreader unit (2) because of wear, the dogs of a dog clutch are rotated one notch further, as a result of which the spreader unit is not completely returned when the brake is released. The original clearance is thus maintained. However, increased actuation travel distances of the spreader unit also occur when, in the case of long braking, the brakes, in particular the brake drum, heat up and thus widen. In this case; however, no adjustment should not be made. Therefore, a blocking device is provided, which consists of a bimetal element, for example in the form of a spiral spring (53). In the event of heating, the blocking device expands and holds the two dogs (19, 27) of the dog clutch at a distance such that the dogs cannot fall into the next notch despite an increased actual travel distance. As a result, adjustment is deliberately prevented. Wear of the pads is compensated during one of the following braking operations in which the brake is not intensely heated.

The invention relates to a motor vehicle disc brake lining (1) comprising friction material (2) which is fixed on the front side of a back plate (3), and with a resetting spring (4) which is fixed releasably or non-releasably on the rear side of the back plate and which has a base (5) and an elastic resetting spring bow (6), and the resetting spring bow is suitable and intended for being supported elastically on an associated abutment (7) of a holder (8) such that the motor vehicle disc brake lining can be reset so as to be axially distanced from a brake disc in the released brake state.
