Abstract
In a drive system for automobiles having two driven axles, a differential gearing between the axles serves at the same time as distributor gearing. A fluid friction clutch is associated with the differential gearing as an optional differential lock thereof. In order to guarantee that the distribution of the driving torques to the two axles can be changed either arbitrarily by hand or automatically on the basis of various operational data, each of the two parts of the fluid friction clutch, adapted for being coupled with each other, is driven from one of two output members of the differential gearing. A preferably continuously adjustable change-speed gearing is associated with one of the two output members. At least one piston drive for acting upon the change-speed gearing and a control unit lodged in an actuating line for the piston drive, as well as a governor for processing operational data of the vehicle or the engine thereof can also be provided.
