A combination starter-generator device is provided for a work vehicle having an engine. The starter-generator device includes an electric machine; a gear set configured to receive rotational input from the electric machine and from the engine and to couple the electric machine and the engine in a first power flow direction and a second power flow direction. The gear set is configured to operate in one of at least a first gear ratio, a second gear ratio, or a third gear ratio in the first power flow direction and at least a fourth gear ratio in the second power flow direction. The starter-generator device further includes a dog clutch arrangement selectively coupled to the gear set to effect the first, second, and third gear ratios in the first power flow direction and the fourth gear ratio in the second power flow direction.

A friction clutch includes a reference plane aligned perpendicular to a rotational axis, a first clutch component, and a second clutch component. The first clutch component has a first friction element, a first support part that receives the first friction element, a leaf spring unit including a leaf spring that rotationally fixes the second support part to the first support part. The second clutch component has a second friction element. The first friction element lies against the second friction element in a frictionally locking manner in a closed position, and is axially spaced from the second friction element in an open position. The leaf spring is designed and positioned relative to the reference plane in a set angle in the closed position such that an additional axial force is applied to the first friction element and the second friction element in a drive rotational direction of the first clutch component.

A drive train unit for a hybrid vehicle includes an input shaft arranged for rotationally fixed attachment to an output of a transmission, an output shaft, an electric machine with a rotor, a clutch, and an actuating unit operatively connected to the clutch. The actuating unit has an actuator and an actuating bearing, displaceable by the actuator. The clutch may be a separating clutch operatively inserted between the rotor and the input shaft, or a friction clutch operatively inserted between the input shaft and the output shaft. The clutch may be a self-intensifying clutch with a leaf spring adjusted at a set angle relative to a reference plane oriented perpendicular to an axis of rotation such that, in a driving direction of a first clutch component, a first friction element is applied to a second friction element with an additional axial force.

A power transmission apparatus for hybrid electric vehicle includes: input shaft coaxially disposed with an engine output shaft receiving engine torque; first and second output shafts coaxially disposed forward and rearward sides on the input shaft; third output shaft coaxial with the first output shaft; a shared drum connected to the input shaft and formed with a motor gear gear-meshed with a motor; an engine clutch sharing the shared drum and selectively transmitting torque between the engine output shaft and the input shaft; first and third clutches disposed in rows within the shared drum and selectively transmitting torque from the input shaft to the first and third output shafts; a planetary gear set disposed on the second output shaft and connected to the second output shaft; and a second clutch external to the planetary gear set and selectively connecting the input shaft and the planetary gear set.

A drive train is used at least including an input shaft and an output shaft. A clutch member is rotatable by a clutch shaft about an axis of rotation. The clutch shaft is supported for lateral movement along the axis of rotation to move the clutch member to cooperate with the drive train at a first lateral position to cause the output shaft to turn and to move the clutch member to a second lateral position to disengage the output shaft from rotation of the input shaft. A permanent magnet is supported by one end of the clutch shaft and arranged for receiving an external magnetic biasing force along the axis of rotation to selectively move the clutch member between the first and second lateral positions. A traveling shaft can be used to support a selected gear for movement by the permanent magnet to implement transmission and reversing configurations.

A drive mechanism for a skidloader including multiple clutch packs, where each clutch pack selectively connects a drive motor to a corresponding wheel assembly via a unique drive path. More specifically, each drive path produces a unique drive ratio between the drive motor and the corresponding wheel assembly such that the drive mechanism is adjustable between a first drive configuration, in which the motor and wheel assembly are in operable communication via first drive path, a second drive configuration, in which the motor and wheel assembly are in operable communication via a second drive path, and a park configuration, in which the motor and the wheel assembly are in operable communication via both the first drive path and the second drive path.

An assembly comprising a drive gear coupled to a shaft and a dial. The drive gear is configured to rotate along a first axis based on movement of the dial. The assembly includes a first linking member located along a second axis and configured to rotate about the second axis based on contact with the drive gear as the drive gear is rotated. The assembly includes a second linking member located along the second axis and configured to rotate about the second axis based on rotation of the drive gear and a coupling between the first linking member and the second linking member. The assembly includes a linking member selector configured to rotate about the first axis and for selecting at least a position corresponding to the first linking member that causes the coupling between the first linking member and the second linking member.
