Abstract
A drive arrangement for a machine includes a first planetary gear set, a second planetary gear set, a third planetary gear set, a first motor, a second motor, and a third motor. The first, second, and third motors are drivingly connected to the first, second, and third planetary gear sets to simultaneously generate fewer than three separate output rotations.
Claims29
A drive arrangement, comprising:
- a first planetary gear set;
- a second planetary gear set;
- a third planetary gear set;
- a first motor;
- a second motor;
- and
- a third motor,
- wherein the first, second, and third motors are drivingly connected to the first, second, and third planetary gear sets, and the first, second, and third motors simultaneously generate two output rotations to independently transmit power to two traction devices.
