Double Differential Unit with Torque Sensing Locking Device

For vehicles with transversely-installed engines and the request to design a four-wheel-drive concept at reduced costs, an alternative to the systems currently on the market is a torque-sensitive system such as the Torque Sensitive Double Differential Unit (TS DDU). In correlation with modern vehicle dynamics controls applying brake intervention, this system with torque- sensitive centre differential lock function is perfectly apt to provide optimum traction and driving behaviour for a customer's application profile. Moreover, the TS DDU allows to reduce the required space for the functions front and centre differential to that of a conventional front bevel gear differential.
