An auxiliary electric power device, which is coupled to a prime mover, provides electric power to convenience outlets, appliances, and heating cooling units. Based on a mode of a transmission coupled to the prime mover, one of a plurality of control schemes is selected to control the power provided by the auxiliary electric power device.

A power shift transmission includes an input shaft and a gear housing including a gear assembly disposed therein. The gear assembly is driven by the input shaft. The transmission also includes an output shaft rotated by the gear assembly. The transmission also includes an auxiliary shaft extending through a portion of the gear housing. The auxiliary shaft is rotated by an internal combustion engine. The transmission also includes a clutch assembly movable from a disengaged position to an engaged position. The clutch assembly includes a first clutch portion coupled to the input shaft and a second clutch portion coupled to the auxiliary shaft. The second clutch portion transmits rotational force to the first clutch portion only with the clutch assembly in the engaged position. The transmission also includes an electric motor including an electric motor shaft in geared relationship with the first clutch portion.

A power take-off includes an input mechanism having an input gear that is rotatably supported on a housing of the power take-off portion. The input mechanism also has a portion that extends outwardly through the opening provided through the mounting surface of the housing of the power take-off portion and that is adapted to extend within and be rotatably driven by the source of rotational energy. The power take-off further includes an output mechanism that is disposed within the housing and includes a driven gear that is rotatably driven by the input gear of the input mechanism. A rotational axis of the input gear and a rotational axis of the driven gear are misaligned so as to minimize the transmission of torque transients and other vibrations therethrough during operation.

A power take-off includes a housing that is adapted to be supported on a source of rotational energy, an input mechanism that is supported within the housing and adapted to be rotatably driven by the source of rotational energy, and an output mechanism that is supported within the housing and rotatably driven by the input mechanism. At least one of the input mechanism and the output mechanism includes a pair of mating gears. An eddy current damper is supported within the housing and configured to exert a drag torque on either or both of the mating gears during operation of the power take-off. The eddy current damper may provide a variable amount of such drag torque, a constant amount of such drag torque, or a combination of both.

In an aspect, a tensioner is provided for tensioning a belt and includes first and second tensioner arms having first and second pulleys respectively. The first and second pulleys are configured for engagement with first and second belt spans, and are biased in first and second free arm directions respectively. A second tensioner arm stop is positioned to limit the movement of the second tensioner arm in a direction opposite the second free arm direction. The second tensioner arm stop is positioned such that, in use, the second pulley is engaged with the endless drive member while the second tensioner arm is engaged with the second tensioner arm stop throughout a first selected range of operating conditions.

A military vehicle includes a chassis, a front axle, a rear axle, an energy storage system, an engine, a transmission, and a motor. The chassis includes a passenger capsule, a front module coupled to a front end of the passenger capsule, and a rear module coupled to a rear end of the passenger capsule. The passenger capsule defines a tunnel extending longitudinally along a bottom thereof. The front module includes a front subframe assembly. The rear module includes a rear subframe assembly. The front axle is coupled to the front subframe assembly. The rear axle is coupled to the rear subframe assembly. The engine is supported by the front subframe assembly. The transmission is positioned within the tunnel and coupled to the front axle and/or the rear axle. The motor is at least partially positioned within the tunnel and positioned between the engine and the transmission.

A work vehicle having an implement includes an engine control unit for controlling an engine and detecting an abnormal state of the engine, a PTO transmission mechanism for transmitting power from the engine to the implement, a PTO clutch for switching ON/OFF power transmission by the PTO transmission mechanism and a clutch control circuit configured to render the PTO clutch OFF based on a detection signal outputted by the engine control unit at time of detection of the abnormal state.

This radiator fan for cooling a radiator has: a rotating member that rotates due to rotation of an engine; blade members that are provided on the peripheral surface of the rotating member such that the angle of surfaces that receive air is changed; a moving member, which is provided in the rotating member, and which moves toward the peripheral surface of the rotating member due to centrifugal force generated by means of the rotation of the rotating member; and a connecting member, which is connected to the moving member and the blade members, transmits the movement of the moving member to the blade members, and changes the angle of the surfaces.

The invention relates to a drive system (1) for an engine arrangement (2), the drive system comprising an epicyclical gear reduction mechanism (20) having a main axis (15) and comprising: a first main gear (123), a second main gear (121) arranged to rotate about main axis (15) in the same direction as the first main gear (123), a first set of planet gears with planet gears (23) meshing with the first main gear (123), a second set of planet gears with planet gears (21) meshing with the second main gear (121), a planet carrier (25), supporting planet gears (23, 21) of the first and second planet gears (23, 21), the planet carrier (25) being located, along the main axis (15), between the first main gear (123) and the second main gear (22, 121). Each planet gear (23) of the first set of planet gears (23) is coupled to a planet gear (21) of the second set of planet gears (21) such that no relative rotation is possible between them. In the mounted position: the first main gear (123) is connected to an engine crankshaft (5), the planet carrier (25) is connected to an accessory pulley (9) which is drivingly connected to an electric machine (6) and at least one accessory (7). The drive system further comprises a free wheel (30) which is connected to a non-rotating part (16) of the engine arrangement in the mounted position. The second main gear (121) is configured to be coupled, preferably via an intermediate junction element (22) of the drive system, to the free wheel (30) in a first operating phase of the drive system (1). In the first operating phase, the free wheel (30) is configured such that when the second main gear (22, 121) exerts torque on the free wheel in one direction, the free wheel is in an engaged state and stops the rotation of the second main gear (22, 121), and when the second main gear (22, 121) exerts torque on the free wheel in the opposite direction, the free wheel is in a free state and allows rotation of the second main gear (22, 121).
