ABSTRACT:
The invention is directed to a brake actuator (2) having a transmission including an electric motor (6) as a drive element, a converting device for converting the rotational movement of the electric motor (6) into a linear movement and a hydraulic transmission (16, 18, 20) for transmitting the linear movement of the converting device to a friction lining (22) of a brake. The brake actuator of the invention does not require a mechanical transmission connected between the motor and the hydraulic transmission. This is achieved with a converting device configured as a spindle unit (12, 14) and is realized in that the spindle nut (12) is fixedly connected to the electric motor (6) and the spindle rod (14) is fixedly connected to a first hydraulic piston (16) of the hydraulic transmission (16, 18, 20). The electric motor is provided with a hollow shaft (10) for accommodating the displacement stroke of the spindle rod.
