Abstract: The invention relates to an electromechanical brake booster for a vehicle brake system, comprising an actuating unit that can be coupled to a brake cylinder. The actuating unit comprises at least one actuating element that can be coupled to an electric motor by means of a transmission. The actuating unit also comprises an actuating member that can be coupled to a force input member. The brake booster comprises at least one housing in which at least sections of the actuating unit are received. At least one damping element is arranged between the at least one housing and at least the at least one actuating element.

Abstract: The present disclosure concerns an assembly (100) for an electromechanical brake booster (200) of a vehicle braking system (1000). The assembly comprises an actuating member (120) which can be loaded with a first actuating force generated by means of a brake pedal, and a housing (160, 160a) in which the actuating member (120) is received, wherein the housing (160, 160a) can be loaded with a second actuating force generated electromechanically. Furthermore, the assembly (100) comprises an output element (150) extending away from the housing (160, 160a). Said element is configured for transmitting the first and second actuating forces to a brake cylinder (300) of the vehicle braking system (1000). Furthermore, an elastically deformable transmission element (140) is provided which is arranged to transmit force in a brake application direction between the actuating member (120) and the housing (160, 160a) on one side and the output element (150) on the other, and is configured to receive the first actuating force from the actuating member (120) and the second actuating force from the housing (160, 160a) and transmit these to the output element (150). According to the present disclosure, a support (160, 160a) that is rigidly arranged on the housing is provided for a portion of the output element (150), wherein the supported or supportable portion of the output element (150) is arranged between the support (180, 180a) on one side and the transmission element (140) on the other.

Abstract: The present disclosure relates to an electrically activatable actuating unit (106) for a motor vehicle brake system (1000), having a housing body (122) and an actuating member (124) arranged in a recess (150) of the housing body (122), wherein the actuating member (124) is coupleable to a brake pedal at a first end and coupleable to a motor vehicle brake (400) at a second, opposite end. The housing body (122) and the actuating member (124) are arranged to be displaceable in a braking direction to actuate the motor vehicle brake (400). The electrically activatable actuating unit (106) furthermore comprises a damping element (180, 180A, 180B), which is arranged in the recess (150) of the housing body (122) such that it abuts frictionally against an outer wall of the actuating member (124) by means of an inner circumferential face (184) and abuts frictionally against an inner wall (170) of the housing body (122) by means of an outer, opposite circumferential face (186), which inner wall delimits the recess (150).
