Abstract

A device for a motor vehicle is provided. The device may comprise an input shaft for supplying torque, a clutch configured for selectively transferring the torque, a first gear configured for connection to the clutch, and a second gear connected to the first gear. The second gear may be fixed to the device so that the second gear is not free to rotate. The device may further comprise an output shaft for receiving the torque. The device may be configured to control the amount of torque transferred to the output shaft.

Description

technical field [0001] The present invention relates generally to apparatus for a motor vehicle, including means for a motor vehicle to transmit sufficient driveline torque by engaging a portion of the driveline torque. Background technique [0002] Motor vehicles may be driven on a variety of surfaces. Different road surfaces have different coefficients of friction. Drivers may lose control when transitioning to a different surface. For example, a driver may oversteer or overcompensate when the road surface changes. A difference in rotation between the front and rear wheels can indicate slippage or loss of traction. Standard-spec tires are flexible enough to absorb about 5% of the difference in rotation between the front and rear wheels. However, in some cases, the rear wheels can turn up to about 6% faster than the front wheels, which would not be handled by the standard-spec tire compliance. The amount of torque delivered to the rear wheels can be varied to improve d...
