A power take-off (PTO) arrangement is provided for transferring power between a work vehicle and an implement. The PTO arrangement includes a PTO shaft having a PTO flange; and a PTO transmission unit having an input shaft coupled to the work vehicle, an output shaft coupled to the PTO shaft, and a gear set coupling the input shaft to the output shaft such that the power is transferred at a speed ratio selected from at least two speed ratios. A PTO speed control system has a sensor arrangement proximate to the PTO shaft and configured to sense data associated with the PTO flange and generate a PTO flange output signal based on the PTO flange data and a control unit and configured to selectively enable and disable operation of the PTO arrangement based on the PTO flange output signal and the selected speed ratio.

The purpose is to provide a working vehicle such that, when a reverse switch coupler is detached, or when a wire connecting a reverse switch to a control device is disconnected, driving of a PTO shaft can be reliably prevented and reliability of the reverse switch can be improved. In a tractor, a reverse switch includes a normally closed type first contact, and a normally open type second contact that is switched in association with the first contact. When an input voltage from the first contact is higher than a set voltage, and when the input voltage from the first contact is lower than the set voltage and an input voltage from the second contact is equal to or lower than the set voltage, a control device controls the actuator such that the PTO clutch is disconnected.

The present disclosure provides a method for controlling a power take-off assembly. The method includes providing a drive unit, a transmission having an output, a speed sensor, a controller including a memory unit and a processor, and the power take-off assembly including a clutch and a solenoid. The method also includes storing a first threshold in the memory unit, determining a current input speed of the drive unit with the speed sensor, and comparing the current input speed to the first threshold. The method further includes controlling an amount of hydraulic pressure supplied to the clutch and engaging the clutch.

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.

A power take-off includes a housing (18) which at least partly accommodates an input shaft (20), at least one output shaft (22), a first transmission device (24) connected to the input shaft (20), a second transmission device (26) connected to the at least one output shaft (22), and at least one offtake module (30) connected to the at least one output shaft (22). The second transmission device (26) and the at least one output shaft (22) are arranged to fit in and be removable from the housing (18). Also, a vehicle (1) provided with such a power take-off (16) and to an intermediate piece (48) for such a power take-off (16).

A method and apparatus for delivering power to a hybrid vehicle is disclosed. The apparatus includes an apparatus for delivering power to a hybrid vehicle, the hybrid vehicle including a powertrain having a power take-off coupling, the powertrain including an engine and a transmission. The apparatus includes an electric motor operable to generate a torque, the motor being coupled to transmit a starting torque through the power take-off of the powertrain for starting the engine.

A power take-off (PTO) system for a motor vehicle includes a PTO housing. The PTO housing is mounted to a transmission case. A disconnect clutch assembly is positioned within the PTO housing acting when supplied with a first volume of a pressurized oil from the transmission case to engage an output shaft member. A controlled lube oil circuit is isolated from the first volume of the pressurized oil. The controlled lube oil circuit supplies a second volume of the pressurized oil directly to the disconnect clutch assembly to lubricate the disconnect clutch assembly. A lube oil drain return is connected to the PTO housing. The lube oil drain return receives oil that collects inside the PTO housing to be returned to the transmission case.

A vehicle with a primary driveline that is configured to distribute rotary power to a first set of vehicle wheels and a power transmitting device that can be selectively operated to transmit rotary power to a secondary driveline. The power transmitting device has an input member, which is driven by the primary driveline, and an output member that is selectively coupled to the input member to receive rotary power therefrom. The secondary driveline comprises a differential, a pair of shafts, and a side shaft coupling that selectively interrupts power transmission between the differential and one of the shafts.

Systems and methods for an electric drive system. The electric drive system, in one example, includes a gearbox that includes a first shaft rotationally coupled to a higher voltage electric motor and a second shaft rotationally coupled to a lower voltage electric generator and motor assembly. The electric drive system further includes an inverter electrically coupled to the higher voltage electric motor and an energy storage device and in such an example, the lower voltage electric generator and motor assembly is configured to rotationally couple to an auxiliary device.
