Abstract
The present invention relates to a drive system for vehicles with at least two drivable vehicle axles (V, H), in particular for utility vehicles and farm tractors. The drive system has an infinitely variable transmission with no intermediate axle differential comprising at least a first () and a second () motor. The first motor () in this case is propulsively connected to a first vehicle axle (H) and the second motor () is propulsively connected to a second vehicle axle (V). Furthermore the drive system has a clutch (), by which a propulsive connection can be made between at least the first (H) and the second (V) vehicle axle, wherein the position of the clutch is adjustable () in a range between an engaged position and a disengaged position, and a control unit (), which actuates the clutch () in such a manner that its torque transmission capacity is adjusted as a function of a driving state of the vehicle.
