A vehicle drive device (1) is disclosed that includes a shift detent mechanism (90); an actuator (74) that generates drive power for allowing the shift detent mechanism to operate; a sensor (135) that generates sensor information indicating an amount of operation of the shift detent mechanism; a control part (153) that controls the actuator; and a clutch (30) that is synchronized with operation of the shift detent mechanism, and when the control part changes a state of the clutch, the control part performs feedback control of the actuator based on a relationship between a target value for an amount of operation of the shift detent mechanism and the sensor information, and before completing the change in the state of the clutch, the feedback control ends and operation of the actuator stops.

A gear seeking shifter having a housing containing a shift lever with a depressible inner push rod. A CAM component is rotatably supported to a base of the shift lever and is driven by a gear seeking motor. An upwardly biased gate pawl is secured to the inner push rod into contact with any of a PRND shifter position gates configured along an opposing underside of said housing. At least one detent pawl is supported within the housing in biasing contact with a detent plate configured upon an opposing inside surface of the housing. The CAM component, upon being rotated by the motor, includes each of a first profile for retracting the gate pawl and a second profile for engaging and inwardly displacing the detent pawl away from contact with the detent plate to permit the CAM component to rotate the shift lever to a desired gear position.

A shift device includes a shift switching member including a plurality of valley portions corresponding to shift positions, a motor including a rotor and a stator and configured to drive the shift switching member, a first drive system including a first inverter configured to output a voltage for driving the motor, a second drive system provided separately from the first drive system and including a second inverter configured to output a voltage for driving the motor; and a positioning member configured to be fitted into any one of the plurality of valley portions of the shift switching member to establish the corresponding shift position. When driving the motor, the shift position is switched by the voltages output from the first drive system and the second drive system.

A drive assembly for a work vehicle has a drive housing including at least one housing element forming a reaction member, a drive shaft rotatable about a drive axis, and a planetary gear set coupled to the drive shaft and configured to selectively rotate an output element. The drive assembly also includes at least one clutch arrangement having at least one clutch ring configured to selectively interact with the planetary gear set to effect a rotation speed of the output element. At least one actuator is configured to axially drive the clutch ring along the drive axis. A retention mechanism is configured to retain the clutch ring at an axial position along the drive axis. The retention mechanism includes a detent ball, a detent groove and a resilient member configured to urge the detent ball into the detent groove to retain the clutch ring at the axial position.

A shift mechanism having a biasing member that operatively connects a detent linkage to a linkage. The biasing member permits an actuator shaft of an actuator and the detent linkage to rotate about an actuator axis with respect to the linkage when a shift collar is inhibited from moving along the axis.

An interchange mechanism for deploying at least one reflector for reconfiguration of a spacecraft antenna. The interchange mechanism includes a rotary actuator having a fixed section mounted on an antenna structure and a mobile section rotating relative to the fixed section about a rotation axis. At least one carrier supports a reflector and is freely rotatably mounted on the fixed section for rotation about the rotation axis between first and second angular positions. An arm mounted on the mobile section carries a carrier engaging mechanism that successively and releasably engages the at least one carrier and displaces the at least one carrier from the first to the second angular position when the arm and the mobile section rotate in a first direction.

A drive assembly for a work vehicle includes a housing arrangement, a drive shaft rotatable in first and second clock directions, and a two-stage planetary gear set coupled to the drive shaft. The gear set includes, or is coupled to, an output element. First and second clutch arrangements are configured to selectively engage the gear set to effect first and second gear ratios, respectively. A step ratio from the first gear ratio and the second gear ratio is 3:1. At least one first actuator and at least one second actuator are configured to effect movement of the first and second clutch arrangements, respectively, to selectively engage the gear set. The drive shaft and the output element rotate in a same clock direction with the first clutch arrangement engaged with the gear set, and in opposite clock directions with the second clutch arrangement engaged with the gear set.

A gear shifting device is provided, by which an axial shift movement of a shift element into a shift position through interaction of a shift pin with an associated groove-like shift gate that is changeable in an axial direction. The shift element features, on an inner diameter and/or an outer diameter, the associated shift gate, while the respective shift pin is arranged in a radially opposite and displaceable manner on a transmission component adjacent to the shift element. As an alternative, the shift element, on an inner diameter and/or an outer diameter, accommodates the respective shift pin in a radially displaceable manner, whereas the associated shift gate for the respective shift gate is arranged to be radially opposite on a transmission component located adjacent to the shift element. The shift pin is movable through an associated actuator in a radial manner between an initial position and a mesh position in which each shift pin is introduced into the associated shift gate.
