A disc brake () is described, comprising a brake disc () and two brake shoes (), which are pressable against both sides of the brake disc () and which in relation to a peripheral force (C') generated upon application of the brake shoes () against the brake disc () are supported against a vehicle-fixed carrier (). The disc brake () moreover comprises at least one device () for measuring and/or converting the peripheral force (C&#x2032;), which device is disposed in a force transmission chain between the brake shoe () and the carrier (). A force transmission member in the form of e.g. a swivel element () is disposed between the brake shoe () and the device () for measuring and/or converting the peripheral force (C&#x2032;) and is movable under guidance parallel to the brake disc ().

A vehicle brake system has a gas pressure accumulator ( ) comprising a housing ( ), the interior of which is divided by metal bellows ( ) into a gas-sensed gas chamber ( ) and a fluid chamber ( ). Via a feed line ( ) a fluid may be supplied under pressure to and removed from the fluid chamber ( ), wherein provided between the fluid chamber ( ) and the feed line ( ) is a valve arrangement ( ), which closes when the pressure in the feed line ( ) drops below a minimum value and opens when the pressure exceeds the minimum value. To increase the operational reliability of the gas pressure accumulator ( ), the valve arrangement ( ) closes when the pressure in the feed line ( ) exceeds a maximum value and opens when the pressure drops below the maximum value.

The invention relates to an actuator assembly for a vehicle brake with a drive which is connected with an input side of a transmission. An output side of the transmission is adapted for the actuation of at least one friction element of the vehicle brake, with the transmission being a knee lever arrangement with two arms.

Actuator assembly for a vehicle brake with such an actuator assembly

The invention relates to an actuator subassembly for a vehicle brake with a drive, which is connected to an input side of a lever arrangement, wherein an output side of the lever arrangement is adapted to operate at least one friction element of the vehicle brake. If a vehicle brake of this kind is used as a parking brake, static preloading forces occur at the friction element.
