The present disclosure concerns an assembly () for an electromechanical brake booster () of a vehicle braking system (). The assembly () comprises a housing () which has a longitudinal axis (L) and can be loaded with an electromechanically generated actuating force, and an output element () which extends away from the housing () and is configured for transmitting the actuating force to a brake cylinder () of the vehicle braking system (). The assembly () furthermore comprises an elastic element () which is supported on the housing () and configured to move the housing () away from the brake cylinder () into a starting position, and a guide () which is arranged on the housing () for the output element () and is configured to guide an angular deflection of the output element () with respect to the longitudinal axis (L) of the housing ().

An electrically actuatable operating unit () for a motor vehicle brake comprises a housing body () which is arranged so as to be displaceable in a braking direction for operation of the motor vehicle brake, a recess () formed in the housing body (), wherein the recess () is delimited at one longitudinal end by a contact shoulder (), a through-opening () delimited by the contact shoulder (), an operating member () which is arranged in the recess () so as to be displaceable for operation of the motor vehicle brake and projects through the through-opening () of the contact shoulder (), wherein the operating member () can be arranged in a force-transmitting manner between a brake pedal and the motor vehicle brake (). The operating unit () further comprises a return spring () which is arranged in the recess () and is configured to move the operating member () relative to the housing body () away from the contact shoulder (), and a sleeve element () which circumferentially surrounds a portion of the operating member () at least partially and is held in contact with the contact shoulder () by the return spring (), and wherein the sleeve element () projects into the through-opening () in such a manner that it is arranged between the operating member () and an inner circumferential surface of the contact shoulder () that delimits the through-opening ().

A brake booster is comprised of an actuation unit, which can be coupled to a brake cylinder. The actuation unit is comprised of at least one actuation element that can be coupled to an electric motor via a transmission and at least one actuation element that can be coupled to a power input element. The actuation unit also includes at least one power transmission element that can be coupled to at least one actuation element in a power-transmitting manner, and at least one power take-up element that can be coupled or is coupled to an actuation detection device for the detection of an actuation of the electromechanical brake booster. The power take-up element can be coupled or is coupled to at least one actuation element. The power take-up element is configured to limit a relative movement of the actuation element relative to the power transmission element.
