ZF's rear-axle drive with integrated all-wheel drive clutch includes a control unit that, together with the electromechanical actuator and the all-wheel drive strategy integrated in the control unit, regulates the torque distribution between front and rear axle. This control unit can also be used to combine the all-wheel drive clutch actuation with other functions, such as advanced safety assistance systems.
The all-wheel drive clutch can be engaged before slip occurs. This forward-looking function leads to ideal traction and thus to improved driving dynamics. The three-piece aluminum housing is equipped with directly integrated suspension arms, which reduces the module's weight and makes it more robust and less costly. Axle drive and clutch share one oil circuit thus increasing the thermal performance.
