ABSTRACT:
A drive device for an engine-driven load, which in the drive direction successively includes an engine, a torque converter with an input shaft and an output shaft, and a continuously variable transmission unit with a primary shaft and a secondary shaft, between which torque can be transmitted with the aid of friction forces. The nominal torque which can be generated by the combination of engine and torque converter on the primary shaft of the transmission unit is greater than the maximum slipping torque of the transmission unit. The device is provided with devices which act on parts of the drive device in such a manner that the torque which can actually be generated in operation by the combination of engine and torque converter on the primary shaft of the transmission unit is limited. The limited level for the torque is controlled in such a manner that the torque generated is at most equal to the maximum slipping torque of the transmission unit.
