Abstract: Systems and methods for a power take-off (PTO) assembly. The PTO assembly, in one example, couples to a shaft and is driven by rotation of the shaft. The PTO assembly includes a disconnect clutch that selectively couples a bi-directional pump to the shaft. The disconnect clutch is passively actuated based on hydraulic system pressure to disengage the disconnect clutch when a prime mover is in operation and engage the disconnect clutch when the prime mover is shut down.

Abstract: An energy recovery drive system includes a motor-generator that is structured to selectively operate in a motor mode and a generator mode. A first shaft is operatively coupled to a transmission power take-off shaft. A second shaft is operatively coupled to the motor-generator and to an alternative power source. The energy recovery drive system is controllably operated in a plurality of operating modes. In a first operating mode, the motor-generator is in torque providing engagement with each of the first and second shafts. In a second operating mode, the motor-generator is in torque communicating engagement with each of the first and second shafts. In a third operating mode, which the motor-generator is in torque communicating engagement with the second shaft and is disengaged from transferring torque to the first shaft and from receiving torque from the first shaft.

Abstract: A method and system for operating a transmission that includes a power take off is described. The transmission selectively delivers mechanical power to the power take off from one of two electric traction motors via selective engagement of either a first or a second power take off clutch based on drive mode. The transmission also allows for powershifting between a first and second operating gear.

Abstract: A tractor includes an engine, a vehicle body, a rear PTO shaft, a central PTO shaft, a permission switch, and a control unit. The engine is configured to generate power. The vehicle body includes an operator's seat. The rear PTO shaft is configured to supply power generated by the engine to a rear work machine attached to a rear part of the vehicle body. The central PTO shaft is configured to supply power generated by the engine to a central work machine attached to a central part of the vehicle body. The permission switch is operable by an operator. The control unit indicates that the permission switch is operated as one of permission conditions for rotation of the rear PTO shaft after disembarkation, and indicates that the permission switch is operated as one of permission conditions for rotation of the central PTO shaft when moving backward.

Abstract: An electrified fire fighting vehicle includes a battery pack, an electromagnetic device, an engine, and a controller. The controller is configured to monitor a state-of-charge of the battery pack, operate the electromagnetic device using stored energy in the battery pack to provide a performance condition including (i) accelerating the electrified fire fighting vehicle to a driving speed of at least 50 miles-per-hour in an acceleration time and (ii) maintaining or exceeding the driving speed for a period of time, and start and operate the engine in response to a start condition to facilitate reserving sufficient stored energy in the battery pack such that the state-of-charge is maintained above a minimum state-of-charge threshold that is sufficient to facilitate the performance condition. The acceleration time is 30 second or less. An aggregate of the acceleration time and the period of time is at least 3 minutes.

Abstract: A power take-off includes a housing including a mounting surface that is adapted to be secured to a source of rotational energy. The mounting surface has an opening therethrough. An input mechanism includes an input gear that has a portion that extends outwardly from the housing through the opening provided through the mounting surface and is adapted to extend within and be rotatably driven about an input gear rotational axis by a driving gear contained within the source of rotational energy. An output mechanism is disposed within the housing and includes a driven gear that is rotatably driven about an output gear rotational axis by the input gear of the input mechanism. The rotational axis of the input gear and the rotational axis of the driven gear are movable relative to one another so as to minimize the transmission of torque transients and other vibrations therethrough during operation.
