Abstract
Systems and methods for improving operation of a power take off are presented. In one example, the power take off may be rotated in two different directions. The approaches may improve operation of a power take off device.
Claims20
A method of operating a power take off (PTO) of a vehicle, comprising:
- rotating a device external the vehicle and different than vehicle wheels via rotating a PTO output by way of rotating a PTO power source in a first direction;
- and
- reversing rotation of the PTO output via rotating the PTO power source in a second direction different than the first direction, the PTO power source positioned in a vehicle driveline.
A method of operating a power take off (PTO) of a vehicle, comprising:
- rotating a mechanical device external the vehicle and other than vehicle wheels via a PTO output by way of rotating a first PTO power source and a second PTO power source, the first PTO power source and the second PTO power source providing positive torque to a vehicle driveline;
- and
- varying output of the first PTO power source and the second PTO power source in response to available output of the second PTO power source.
A method of operating a power take off (PTO), comprising:
- operating the PTO in a stationary parked vehicle, the PTO operated in a stationary mode;
- rotating a PTO output via rotating a first PTO power source in a first direction and a second direction in the stationary mode;
- and
- rotating the PTO output via a positive torque provided by the first PTO power source and a positive torque provided by a second PTO power source in the stationary mode.
