Abstract

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.
