Abstract:
1. Brake force generator for a vehicle hydraulic brake system having a force input element, which is connectable or connected to a brake pedal and displaceable in a base housing of the brake force generator, a master cylinder having a cylinder housing, in which a primary piston is displaceably guided, wherein the primary piston with the master cylinder delimits a primary pressure chamber for generating a hydraulic brake pressure, a pedal counterforce simulating device, a pedal actuation detecting device for detecting a pedal actuation and an actuating force generating device for exerting an actuating force on the primary piston, wherein the actuating force generating device comprises a control valve, a chamber arrangement and an electromagnetic actuator, wherein the chamber arrangement is designed with a vacuum chamber and a working chamber, which is separated from the vacuum chamber by a movable wall and is fluidically connectable to the vacuum chamber by the control valve, and wherein the control valve in accordance with the detected pedal actuation may be activated by the electromagnetic actuator in order to achieve a pressure difference between working chamber and vacuum chamber that determines the actuating force wherein the pedal counterforce simulating device is workingly connectable to the force input element by a pedal counterforce hydraulic system, which comprises a pedal counterforce simulating device wherein the pedal counterforce simulating device is integrated in the cylinder housing or provided as a separate module thereon.
