BRAKE TEST BENCH HAVING AN ELECTRICAL BRAKE ACTUATOR

摘要

The invention relates to a test bench for a brake comprising a mechanically actuatable pressure generating device (4) for providing a brake fluid having an elevated hydraulic pressure, wherein the brake fluid can be supplied to the brake (3) in order to actuate the brake (3). In order to mechanically actuate the pressure generating device (4), an electromechanical brake actuator (7) is provided, which should simulate the braking foot of a motor vehicle driver. The brake actuator (7) has an electric motor (8) that can be controlled by a test bench controller and a planetary roller screw drive (9) driven by the electric motor (8). The planetary roller screw drive (9) is mechanically coupled to the pressure generating device (4) in order to mechanically actuate the pressure generating device (4).
