Abstract
A method and system for operating a transmission that includes two power take off devices is described. In one example, an internal combustion engine and/or an electric machine may supply power to accessory devices via first and second power take off devices. Alternatively, power may be delivered to the transmission via one or both of the first and second power take off devices.
Claims20
A transmission, comprising:
- a first power take off port including a power take off shaft that rotates at a multiple of a rotational rate of a first shaft, the first shaft coupled to a first planetary gear set;
- a second shaft configured to deliver power to vehicle wheels, the second shaft coupled to planetary gears of the first planetary gear set;
- and
- a second power take off port, the second power take off port coupled to a sun gear of the first planetary gear set.

A method for operating a transmission, comprising:
- receiving energy to the transmission, the transmission including a first power take off and a second power take off, the first power take off coupled to a first planetary gear set, the second power take off selectively coupled to the first planetary gear set via a power take off clutch;
- and
- rotating a shaft of the first power take off while rotating a shaft of the second power take off at a different speed than a rotational speed of the first power take off.
A transmission, comprising:
- a first power take off port including a power take off shaft that rotates at a multiple of a rotational rate of a first shaft, the first shaft coupled to a first planetary gear set;
- a second shaft configured to deliver power to vehicle wheels, the second shaft coupled to planetary gears of the first planetary gear set;
- a second power take off port, the second power take off port coupled to a sun gear of the first planetary gear set;
- two brakes;
- and
- a controller including executable instructions stored in non-transitory memory that cause the controller to adjust operating states of the two brakes to deliver power via the second power take off.
