Patent ID: 8881585

Claim:
A test bench for at least one of motor vehicles or axles of motor vehicles for simulating gyroscopic torques of a rotating wheel, the test bench comprising a wheel replacement system connected to an axle of the motor vehicle and including a wheel replacement mass and a driver for driving the wheel replacement mass, the driver beings attached to a mount and including an electric motor and a drive wheel connected to the electric motor, the drive wheel making contact with a circumferential face of the wheel replacement mass and including a running face formed of a synthetic material, and an arrangement for applying testing forces, testing torques and testing movements in at least one of a longitudinal, lateral or vertical direction to at least one of the motor vehicle or the axles of the motor vehicle, wherein: the driver for driving the wheel replacement mass is configured to set the wheel replacement mass in rotation, and the arrangement for applying testing forces, testing torques and testing movements is configured to generate a gyroscopic torque of the wheel replacement mass which is set in rotation, by applying testing forces, testing torques and testing movements in at least one of the longitudinal, lateral or vertical direction to at least one of the motor vehicle or the axles of the motor vehicle.
