Abstract

The invention concerns a drive unit for a tracked vehicle with a first and a second electric generator (6, 8) and with a first and a second internal combustion engine (10, 12), such that one generator (6, 8) can be driven respectively by one combustion engine (10, 12), and with electric drive motors (14, 16, 18, 20) for driving a right-hand and a left-hand drive track (4, 2). According to the invention it is proposed that the elements of the drive unit are linked in such manner that the right-hand drive track (4) is associated with first and second right-hand electric drive motors (14, 16), the left-hand drive track (2) is associated with first and second left-hand electric drive motors (18, 20), the two first drive motors (14, 18) being fed by the first generator (6) and the two second drive motors (16, 20) being fed by the second generator (8). Due to the wiring of the energy paths according to the invention, very great operational security is achieved even when the drive unit is partially damaged.
