摘要： A method for controlling the engagement of a power take-off (PTO) clutch of a work vehicle may generally include implementing one or more recovery actions to prevent the clutch from being damaged and/or to prevent the vehicle's engine from stalling. For instance, an energy-related recovery action may be implemented when an estimated clutch energy transmitted through the PTO clutch is greater than or equal to a maximum allowable clutch energy associated with the clutch. In addition, or as an alternative thereto, a stall-related recovery action may be implemented when the engine speed is less than or equal to a predetermined engine stall speed and the speed deceleration rate for the engine is greater than or equal to a predetermined deceleration rate threshold.

摘要： A method for controlling engagement of a power take-off (PTO) clutch of a work vehicle may generally include transmitting, by a computing device, a control signal associated with initiating engagement of the PTO clutch, determining a clutch slippage energy generated during engagement of the PTO clutch due to clutch slippage and, while the PTO clutch is getting engaged, calculating a clutch engagement time remaining until engagement of the PTO clutch is completed based on the clutch slippage energy and a maximum clutch engagement energy associated with the PTO clutch. In addition, the method may include determining a torque command for controlling engagement of the PTO clutch as a function of the remaining clutch engagement time and controlling the engagement of the PTO clutch based on the torque command.

摘要： A method includes measuring a parameter indicative of a measured torque in a PTO clutch, determining an incremental torque based at least in part on proportional-integral-derivative (PID) control logic, determining a command torque, wherein the command torque is a sum of the measured torque and the incremental torque, generating a control signal, wherein a current of the control signal corresponds to the command torque and a pressure in a cylinder of the PTO clutch, providing the control signal to the PTO clutch, reducing the incremental torque if an engagement power exceeds an engine power output, and ceasing engagement if an energy absorbed by the clutch exceeds an energy rating of the PTO clutch.

摘要： A power take-off (PTO) drive assembly for a transmission includes a shaft defining a shaft axis, a PTO gear defined radially about the shaft axis, and a clutch assembly positioned between the shaft and the PTO gear and having an engaged position and a disengaged position. When the clutch assembly is in the engaged position, torque is transferred from the shaft to the PTO gear. When the clutch assembly is in the disengaged position, torque is not transferred from the shaft to the PTO gear.

摘要： A method for controlling PTO clutch engagement includes determining a first change in clutch speed based on an inertial load of a PTO implement. The method also includes determining a second change in clutch speed based on a threshold amount of energy of a PTO clutch. The method further includes determining a third change in clutch speed between the first change in clutch speed and the second change in clutch speed. The method also includes adjusting a clutch current based on the third change in clutch speed.

摘要： A system includes an engine, a transmission driven by the engine, and a controller. The controller is configured to receive a speed input, receive feedback indicative of a load of the engine at a current engine speed, compare the load to a predetermined load threshold at the current engine speed, determine an expected engine speed based at least on the current engine speed, a current gear ratio, and an expected gear ratio, determine an estimated engine power at the expected engine speed and a current engine power at the current engine speed, and command a gear downshift when the load is greater than or equal to the predetermined load threshold and when the estimated engine power is greater than the current engine power.

摘要： A hollow double-acting cylinder assembly may be mounted over a shaft and to a housing. A moveable piston of the cylinder assembly connects to a sliding sleeve of an over-center mechanism and the sliding sleeve with a thrust bearing allowing it to push and pull the sleeve mechanism with cylinder action. A toggle action of the over-center mechanism locks clutch without the need to sustain pressure on the cylinder after engagement/disengagement motion. As the clutch is typically engaged for sustained periods of time, this prevents constant hydraulic pressure applied to the over-center mechanism and significantly reduces wear. Hydraulic/pneumatic hoses may pass through the housing and connect to engage and disengage bores of the cylinder via remotely actuated control valve(s).

摘要： A secondary drive device of a mobile working appliance with an electronic control unit for actuating a power take-off shaft clutch arranged between a transmission and a power take-off shaft is disclosed. According to the disclosure, the control unit is designed with a flange-mounting function unit which, when activated, executes a rotary position correction of the power take-off shaft with respect to the drive shaft. Furthermore, a method for coupling and/or uncoupling a working machine to/from the secondary drive device of a mobile working appliance as an energy source is proposed. The method includes the steps of leading a drive shaft of the working machine up to the end spline shaft profile of a power take-off shaft of the secondary drive device, checking the relative rotary position of the power take-off shaft with respect to the drive shaft of the working machine, and selectively triggering a flange-mounting function of the secondary drive device as a function of the result of the check of the relative position for the electronically controlled rotary position correction of the power take-off shaft with respect to the drive shaft.
