VEHICLE AXLE HAVING ELECTRIC DRIVE MOTORS, AN ELECTROHYDRAULIC BRAKE AND ADDITIONAL MODULES SUCH AS A TRANSMISSION, TORQUE VECTORING AND A PARKING BRAKE

摘要

The invention relates to a vehicle axle (VA, HA) having hydraulically operating wheel brakes (RB1, RB2; RB3, RB4) and/or additional hydraulic loads, in particular clutch plate cylinders, comprising the following components: at least one pressure supply device (DV1, DV2) for controlling the pressure in the wheel brakes (RB1-RB4, H-EMB), which pressure supply device is driven by an electric-motor drive (M1, M2); at least one electronic open-loop and closed-loop control device (DV ECU1, DV ECU2) and a valve assembly (HCU) having values for setting wheel-specific brake pressures and/or for disconnecting the wheel brakes (RB1, RB2, RB3, RB4, H-EMB) from or connecting the same to the pressure supply device (DV1, DV2); at least one electric drive motor (TM, TM1, TM2) for driving and braking a vehicle wheel or the vehicle axle, characterized in that at least one pressure supply device (DV1, DV2) is used to control the pressure of and/or provide pressure to at least one additional brake unit (BA) in the form of an electric parking brake (EPB), a hydraulically supported electromechanical brake (H-EMB), an electromechanical brake (EMB) and/or a force-supporting, in particular hydraulically operating, steering device (EPS), a gear actuator and/or transmission actuator, and/or a torque vectoring module.
