Abstract
Methods and systems for a powertrain system. The powertrain system includes a first traction motor and a reduction planetary gear set rotationally coupled to the first traction motor. The powertrain system further includes a power take-off (PTO) that is configured to attach to an implement, and an input shaft rotationally coupled to the first traction motor and a transmission, where the reduction planetary gear set has a grounded component.
Claims15
A powertrain system, comprising:
- a first traction motor;
- a reduction planetary gear set including:
- a sun gear rotationally coupled to the first traction motor;
- and
- a carrier rotationally coupled to a power take-off (PTO) via one or more components that are external to the reduction planetary gear set, wherein the PTO is configured to attach to an implement;
- an input shaft rotationally coupled to:
- the first traction motor;
- and
- a transmission via a gear;
- a second traction motor rotationally coupled to the transmission;
- and
- a transmission disconnect clutch configured to selectively disconnect the first traction motor from the transmission;
- wherein the reduction planetary gear set includes a ring gear that is permanently grounded;
- and
- wherein the transmission is rotationally coupled to one or more drive axles.
12 more elements
A method for operation of a powertrain system, comprising:
- selectively disconnecting a power take-off (PTO) from a first traction motor through operation of a PTO clutch;
- and
- selectively disconnecting the first traction motor from the transmission via operation of a transmission disconnect clutch while a second traction motor that is rotationally coupled to the transmission is operational;
- wherein the powertrain system includes:
- the PTO clutch;
- the first traction motor;
- the second traction motor;
- the transmission disconnect clutch;
- a reduction planetary gear set rotationally coupled to the first traction motor and including:
- a carrier rotationally coupled to the PTO via one or more components that are external to the reduction planetary gear set, wherein the PTO is configured to attach to an implement;
- and
- a ring gear that is permanently grounded;
- wherein the PTO is configured to attach to an implement;
- and
- an input shaft rotationally coupled to the first traction motor and coupled to a transmission via a gear.
12 more elements
An all-electric vehicle (EV) powertrain system, comprising:
- a first traction motor;
- an input shaft rotationally coupled to the first traction motor and a transmission;
- and
- a reduction planetary gear set including:
- a sun gear rotationally coupled to the input shaft;
- a carrier rotationally coupled to a power take-off (PTO) clutch via one or more components, wherein the PTO is configured to attach to an implement;
- and
- a ring gear that is permanently grounded;
- a second traction motor rotationally coupled to the transmission;
- a transmission disconnect clutch configured to selectively disconnect the first traction motor from the transmission;
- and
- a controller including instructions that when executed, during operation of the first traction motor and the second traction motor, cause the controller to:
- disengage the transmission disconnect clutch;
- and
- engage the PTO clutch;
- wherein the PTO clutch is configured to selectively disconnect the reduction planetary gear set from the PTO which is configured to attach to an implement.
