Abstract: An electrohydraulic actuator for a brake system. The actuator includes: a housing defining an interior space and having first and second openings; a master brake cylinder positioned in the first opening and attached to the housing so that the first opening is sealed in a fluid-tight manner; an electric motor arranged on the housing; and a transmission in the interior space and kinematically coupled to the master brake cylinder. The transmission includes a transmission intermediate part which is moveable along a longitudinal axis and subdivides the housing, into a first housing region in which the master brake cylinder is arranged, and a second housing region facing the second opening. The actuator includes a compensating membrane closing the second opening in a fluid-tight manner and elastically deformable to reduce a pressure difference between the first and second housing region when an axial displacement of the transmission intermediate part occurs.

Abstract: An actuating device for a brake system. The actuating device includes an actuatable master brake cylinder, with a transmission device, which includes a displaceably mounted transmission element, with an electric motor for driving the transmission device, with a displaceably mounted pressure force transmitter, which is connected to an input rod in such a way that the pressure force transmitter is displaceable by the input rod, wherein the master brake cylinder is actuatable both by a displacement of the transmission element as well as by a displacement of the pressure force transmitter, and with a sensor, which includes a first sensor part that is displaceable together with the pressure force transmitter and a second sensor part that is displaceable together with the transmission element. The first and the second sensor parts are displaceably mounted on a common carrier element of the sensor.

Abstract: An actuation device for a brake system. The actuation device includes: an electric machine, wherein a rotor of the electric machine is arranged on a rotatably mounted drive shaft in a rotationally fixed manner; a displaceably mounted pressure element; and a transmission device, using which the drive shaft is operatively connected to the pressure element, wherein the transmission device has a displaceable threaded spindle, wherein a rotation-locking element is rotationally fixed to the threaded spindle, and wherein the rotation-locking element interacts with a housing of the actuation device and/or with an element of the actuation device that is arranged on the housing in a fixed manner, in order to form an anti-rotation device for the threaded spindle. The rotationally-fixed connection between the rotation-locking element and the threaded spindle is formed by a form-fitting connection.
