A dual clutch transmission comprises a housing formed therein with a gear chamber incorporating an odd-numbered speed gear train group and an even-numbered speed gear train group. An end of the input shaft is connected to an engine, and a cover is detachably attached to the housing opposite the end of the input shaft so as to define a clutch chamber divided from the gear chamber. A first clutch for the odd-numbered speed gear train group and a second clutch for the even-numbered speed gear train group are disposed in the clutch chamber. Fluid passages for supplying hydraulic fluid to the first and second clutches are formed in the cover.

A hybrid power module efficiently delivers both hydraulic power and electric power. The hybrid power module may regenerate and store energy for later use. The module includes and engine and an electric motor for driving a hydraulic pump. The electric motor is operable as a starter motor for the engine and as an assist motor cooperating with the engine to power the hydraulic pump to improve dynamic response of the hydraulic pump. The module also includes an electric power source which may have an energy storage unit, and the electric motor may be operated as an electric generator providing electric energy to the energy storage unit.

The present disclosure relates to an arrangement of auxiliary assemblies in a combustion machine including an electric machine which is operable as a generator and preferably also as a motor. The arrangement further includes an expansion machine, in particular an expansion machine of a waste heat recovery system for converting waste heat of the combustion machine or of an engine braking system into utilizable energy by way of a steam circuit, and a first group of auxiliary assemblies, including a water pump, a fuel predelivery pump, a high-pressure fuel pump, a steering assistance pump and an oil pump.

The present disclosure relates to an auxiliary drive of a combustion machine, in particular of a combustion machine of a utility vehicle. The auxiliary drive includes a shaft which is operatively connected to a crankshaft of the combustion machine and which has two shaft ends which are designed in each case for connection to a power-outputting and/or power-receiving machine arranged outside the crankcase.

An industrial work vehicle including a frame and a first shaft rotatably connected to the frame via first and second bearings. The work vehicle further includes a second shaft rotatably positioned in line with the first shaft and connected to the first shaft via a coupling. The second shaft is further connected to the frame via a third bearing. The coupling includes a first connection and a second connection. The first connection connects the first shaft to the second shaft via a fourth bearing adapted to support a radial load and to accommodate an axial rotation and an angular misalignment of one shaft with respect to the other shaft. The second connection connects the first shaft to the second shaft via flange elements which are interconnected via an intermediary element adapted to transmit a torque and to accommodate a misalignment of one shaft with respect to the other shaft.

The present invention provides improved, real time sensing of pressure supplied to the hydraulic operator of a clutch for a motor vehicle driveline power take off. A proportional sensor in the hydraulic line to the power take off clutch actuator provides a data signal in real time of the actual pressure applied to the clutch actuator. This signal is provided to the power take off control module (PCM) and/or to the transmission control module (TCM). The power take off control module, having instantaneous data regarding the pressure applied to the hydraulic operator achieves two important operating functions: monitoring and feedback.

A hydraulic power take-off, PTO, is provided for use with industrial drives. The hydraulic power take-off has a multi-position adapter that allows the PTO to be attached to a prime mover in a multitude of angularly indexed positions while maintaining a gravity-assisted drain and sump for the hydraulic fluid. The multi-position adapter is indexable to selectively block and allow for passage of oil from a tower housing to a clutch housing thus ensuring the hydraulic oil properly drains. As a result, the tower housing is also indexable which allows the PTO unit to be installed in a number of different configurations to meet the demands of the prime mover and the final application of the industrial machine.

A clutch system includes a rotary input member, a wrap spring clutch and a rotary output member. The wrap spring clutch has a first end, a second end, and a plurality of coils. The stiffness of the wrap spring clutch is selected such that, when transmitting less than a selected coil engagement torque, the clutch system transmits torque helically from the rotary input member, to the second end, helically through the wrap spring clutch to the first end, and into the rotary output member. When transmitting more than the selected coil engagement torque, the clutch system transmits torque in parallel from the rotary input member, to the second end, helically through the wrap spring clutch to the first end, and into the rotary output member, and from the rotary input member through the coil engagement surface, to the first end, and into the rotary output member.

Accessory transmission for an engine of a motor vehicle has a first pulley adapted to be connected to a crankshaft of the engine, a second pulley adapted to be connected to a shaft of an electric machine through a one-way clutch, and a belt connecting the first and the second pulley to one another in order to rotate in one and the same rotation direction (R). The one-way clutch is configured so as to couple the second pulley to the shaft of the electric machine when the electric machine drives the second pulley in the rotation direction, and to decouple the second pulley from the shaft of the electric machine when the second pulley tends to overrun the electric machine in the rotation direction.

An AC generator for a vehicle includes a housing having an inlet and an outlet, a stator fixed to the housing, a rotor disposed inside of the stator, a cooling fan fixed to a rotor, one or more cooling fins disposed in an air flow passage of a cooling air, and a rectifying element for rectifying an AC voltage generated by a stator winding. A positive-side cooling fin has a plurality of tapered first and second cooling holes penetrating in a thickness direction and serves as the air flow passages of the cooling air. Tapering directions of tapered surfaces extending in the thickness direction of each cooling hole in at least one pair of adjacent first and second cooling holes are reversed in the thickness direction with respect to each other.
