Brake actuator

摘要

A brake actuator includes an electric motor, a conversion device for converting the rotational movement of the electric motor into a linear movement and a hydraulic transmission for transmitting the linear movement of the conversion device to an adjusting piston of a brake. The conversion device includes at least two adjusting elements which can be driven by the electric motor and by way of which the at least two hydraulic pistons of the hydraulic transmission can be operated independently of one another in a hydraulic chamber which can be selectively connected with a reservoir.
