摘要： The invention relates to a drive unit for a track-laying vehicle, with a first and a second electrical generator (6, 8), a first and a second internal combustion engine (10, 12), whereby each one generator (6, 8) may be driven by an internal combustion engine (10, 12) and electrical drive motors (14, 16, 18, 20), for driving a right and a left drive track (4, 2). According to the invention, the elements of the drive unit are linked together, in such a way that a first and a second right electric drive motor (14, 16) are dedicated to the right drive track (4) and that a first and second left electric drive motor (18, 20) are dedicated to the left drive track (2) and that both first drive motors (14, 18) are fed by the first generator (6) and both second drive motors (16, 20) are fed by the second generator (8). Said circuit configuration for the energy path permits a very high operating security, even with partially damaged drive units.

摘要： The invention relates to a drive system for a vehicle, comprising a right-hand (34) and a left-hand drive wheel (36) that are driven by at least one electric motor (14, 16, 18, 20) and one transmission (30, 32). The invention is characterized in that the transmission (30, 32) comprises a mechanical, continuously adjustable transmission unit (50, 52). The continuously adjustable transmission unit (50, 52) allows for extension of the range of adjustment of the drive with respect to torque and maximum speed without interruption of tractive force, and makes it possible to fall back on powerful components.
