Abstract
A multi-motor drive system for a work machine has a first traction device and a second traction device substantially aligned transversely of a primary travel-direction of the work machine. The drive system also has a first drive-group power-transfer system that connects the first traction device and the second traction device. The drive system may also include a third traction device and a fourth traction device substantially aligned transversely of the primary travel-direction of the work machine. Further, the drive system also includes a second drive-group power-transfer system that connects the third traction device and the fourth traction device. Additionally, the drive system has an inter-group power-transfer system that connects the first drive-group power-transfer system to the second drive-group power-transfer system. A first drive motor may operatively connect to the first drive-group power-transfer system separate of the inter-group power-transfer system. Moreover, the drive system may include a second drive motor operatively connected to the second drive-group power-transfer system separate of the inter-group power-transfer system.
