Electromechanical brake pressure generator for motor vehicle brake system, has force inlet unit coupled with pedal and simulation device that works against shifting of inlet unit and remains ineffective during malfunction of rotary drives

摘要

The generator has a force inlet unit (12), which is coupled with a brake pedal and a pedal counterforce simulation device. A threaded spindle-nut arrangement has rotatably drivable components that are provided in a housing (16). The simulation device works against a shifting of the force inlet unit in a normal operation situation by using reaction forces developed by rotary drives of the rotatably drivable components of the threaded spindle-nut arrangement. The simulation device remains ineffective during a malfunction of the rotary drives of the threaded spindle-nut arrangement.
