Abstract
Systems and methods for a power take-off (PTO) assembly. The PTO assembly, in one example, includes a bi-directional pump in fluidic communication with a fluid reservoir and a hydraulic system and a disconnect clutch configured to mechanically disengage and disconnect the bi-directional pump from a transmission when a prime mover is in operation, and mechanically engage and connect the bi-directional pump to the transmission when the prime mover is shut down. The PTO assembly further includes an electro-mechanical valve configured to trigger engagement and disengagement of the disconnect clutch.
Claims20
A vehicle transmission system, comprising:
- a power take-off (PTO) including:
- a bi-directional pump in fluidic communication with a hydraulic system;
- a disconnect clutch configured to:
- selectively mechanically connect and disconnect the bi-directional pump based on an operational state of a prime mover;
- and
- an valve configured to trigger engagement and disengagement of the disconnect clutch.
A method for operation of a transmission system, comprising:
- selectively mechanically connecting and disconnecting a bi-directional pump based on an operational state of a prime mover via operation of a disconnect clutch;
- wherein the transmission system includes:
- a power take-off (PTO) including:
- the bi-directional pump in fluidic communication with a hydraulic system;
- the disconnect clutch;
- and
- an valve configured to trigger engagement and disengagement of the disconnect clutch.
A system, comprising:
- a power take-off including:
- a bi-directional pump in fluidic communication with a hydraulic system;
- a clutch that mechanically connects and disconnects a multi-speed transmission from the bi-directional pump;
- and
- a solenoid valve that permits and inhibits fluid flow to an actuator of the clutch;
- and
- a controller configured to:
- energize the solenoid valve to permit fluid flow to the actuator to disengage the clutch.
