Abstract
A traction drive system for a work machine, including at least one electric motor, a transmission, and a controller. The controller is configured to select a gear ratio of the transmission depending on a change to be expected in a motor output of the at least one electric motor. The change to be expected in the motor output is conditional on a change in the gear ratio of the transmission. The change to be expected in the motor output is determined on the basis of at least one operating parameter of the work machine.
Claims12
A traction drive system for a work machine, comprising:
- at least one electric motor
- a transmission;
- and
- a controller which is configured to select a gear ratio of the transmission depending on a change to be expected in a motor output of the at least one electric motor,
- wherein the change to be expected in the motor output is conditional on a change in the gear ratio of the transmission, and
- wherein the change to be expected in the motor output is determined on the basis of at least one operating parameter of the work machine.
A method for operating a traction drive system for a work machine which has at least one electric motor and a transmission, the method comprising:
- determining, on the basis of at least one operating parameter of the work machine, a change to be expected in a motor output of the at least one electric motor, which change is conditional on a change in a gear ratio of the transmission;
- and
- selecting the gear ratio of the transmission depending on the change to be expected in the motor output.
