Abstract: A method for supplying vacuum for a pneumatic brake booster for a motor vehicle braking system, using an electromotively-driven displacement type pump assembly. At least one pressure sensor for monitoring a pneumatic pressure is associated with the pump assembly, and electric signals of the pressure sensor are fed to an electronic unit, analyzed, and processed in order to regulate the pressure. A plausibility check of the pressure sensor signal is carried out by a pressure value amplitude being determined, by signal analysis, in the form of a difference between a maximum pressure value and a minimum pressure value within a stroke of the displacement element, and this being compared to a stored comparison value wherein if the pressure value amplitude deviates from the comparison value by a defined amount, the signal of the pressure sensor is then defined as implausible.

Abstract: A spindle drive has a spindle nut (1) and a threaded spindle (2) mounted in a rotationally fixed and axially displaceable manner on a reference body (3) by way of a linear guide, wherein the axis (9) of the threaded spindle (2) is arranged parallel to the longitudinal direction of the linear guide, and wherein the linear guide has a groove (4) and a guide element (5) engaging in the groove and comprises an elastic region (5b, 5b?, 5b?), the width of which perpendicular to the longitudinal direction of the linear guide is greater than the maximum groove width in the region used for the linear guide.

Abstract: A force measuring device for a parking brake of a vehicle has a housing, having a Bowden cable for actuating the parking brake and having a force measuring element for determining the cable force. The Bowden cable is guided through the housing and has first and second stops which are fastened to the Bowden cable, wherein under loading of the Bowden cable, the first stop is fixedly supported on a housing inner side and the opposite, second stop is supported on the force measuring element which is provided between the housing and the second stop, wherein a movement of the second stop is generated corresponding to the loading of the Bowden cable, which movement leads, at the force measuring element, to a corresponding measurement value for the force transmitted by the Bowden cable. The force measuring device is provided for parking brakes for passenger vehicles.

Abstract: A gear mechanism for a brake system can be coupled on the inlet side to an actuating drive of the brake system via a drive shaft which can be driven rotationally by the actuating drive. The gear mechanism can be coupled on the output side to a brake unit of the brake system via an output shaft. The brake unit has at least one brake. The gear mechanism has a first and a second gear train having different transmission ratios. Furthermore, the gear mechanism is configured in such a way that, in order to apply the brake, only the first gear train and, in order to release the brake, only the second gear train of the gear mechanism transmits a drive torque of the actuating drive to the output shaft. The transmission ratio of the second gear train is greater than the transmission ratio of the first gear train.

Abstract: An actuating device has an electric motor actuator, at least one output shaft coupled to at least one positioning element and a braking to stop device coupled with the electric motor actuator on the input side and with the output shaft on the output side or includes the output shaft. The braking to stop device has a brake body coupled with the output shaft and is arranged such that it is axially displaceable. The braking to stop device is constructed such that it makes it possible to convert a rotational motion on the input side into the axial lifting motion of the braking body for the displacement thereof from a braking position or positioning the braking body in a braking position. The braking to stop device is also constructed in such a way that it transmits the rotational motion on the input side to the braking body.

Abstract: An actuator system (5) has an electric actuating drive (7) and a first and a second output shaft. The actuator system (5) additionally has at least one actuating element which is coupled to the first output shaft and/or to the second output shaft. The actuating element is designed for coupling to a transmission element. In conjunction with the transmission element, the actuating element converts a rotary motion of the first output shaft or of the second output shaft into a linear motion of the transmission element. In addition, the actuator system (5) has a differential which is coupled on the input side to the electric actuating drive (7) and which has the first output shaft and the second output shaft. The differential is designed to transmit and distribute an input-side torque to the first output shaft and the second output shaft.
