Abstract:
A hydraulic vehicle brake comprising a housing and a brake piston arranged therein, which acts upon a friction member and which, by means of hydraulic pressure which can be supplied into a hydraulic chamber cooperating with the brake piston, can be moved into an actuating position in which it presses the friction member against a rotor of the vehicle brake, and having a spindle/nut arrangement driven by an electric motor, the spindle/nut arrangement arranged coaxially to a center axis of the brake piston, for the mechanical blocking of the brake piston in the actuating position, the nut of the spindle/nut arrangement is secured against rotation and, by rotation of the spindle, can either be moved into contact with the brake piston or moved away from the brake piston translatorily depending on the sense of rotation, with a reduction gear being connected between the electric motor and the spindle, characterized in thatthe reduction gear is designed to be multi-stage, in particular two-stage, and that one gear stage is designed as a belt gear, in particular, as a toothed-belt gear; the electric motor is arranged laterally adjacent to the vehicle brake housing in such a manner, that an output shaft of the electric motor extends at a lateral distance parallel to the center axis and exits from the electric motor at a side facing away from the brake piston; the electric motor and the reduction gear are designed as a subassembly which can be handled separately; and the subassembly can be mounted at the housing in any angular position with respect to a surface of same.
