  • BRAKE DEVICE, IN PARTICULAR FOR ELECTRICALLY DRIVEN MOTOR VEHICLES
    Publication number: 20230016413
    Abstract: A brake apparatus, for electrically driven motor vehicles, includes a traction motor at an axle of a vehicle, which traction motor is used both as drive motor and as brake system with recuperation of brake energy, a first piston-cylinder unit, which is actuatable by means of an actuating device, in particular brake pedal, a second piston-cylinder unit, which is actuatable by means of an electromotive drive and a non-hydraulic gearing apparatus, in particular spindle drive. The piston-cylinder units are connected via hydraulic connecting lines to wheel brakes of the motor vehicle. A pressure chamber of the first piston-cylinder unit is connected to two wheel brakes of a vehicle axle, and a pressure chamber of the second piston-cylinder unit is connected to a vehicle axle for active brake force feedback control and recuperation control in interaction with the traction motor.
