  • Patent number: 10315515
    Abstract: Some embodiments are directed to a pinion shaft assembly of a power transfer unit for transferring torque from an output gear of a transmission to a driveline structure of a vehicle. The embodiments include a hollow shaft that includes an internal splined portion, a pinion gear connected to a first end of the hollow shaft, and a coupling member that includes a flange and a coupling extension extending from the flange. The coupling extension includes an external splined portion at a first end such that the coupling extension mounts coaxially within the hollow shaft. The internal splined portion of the hollow shaft meshes with the external spline portion of the coupling extension in a spline connection for coupled rotation of the hollow shaft and the coupling extension, and the flange is disposed external to the hollow shaft and configured to be connected to the driveline structure.

  • Patent number: 6892600
    Abstract: A changing system in a manual transmission is provided. An interlock plate is mounted on a shift-selecting shaft capable of being moved axially in response to a selecting operation and turned about an axis in response to a shifting operation, so that the interlock plate cannot be turned about an axis of the shift-selecting shaft. The interlock plate has a pair of side plate portions which are provided at locations spaced apart from each other in an axial direction of the shift-selecting shaft and through which the shift-selecting shaft extends. A shifting arm disposed between the side plate portions is fixed to the shift-selecting shaft. In such changing system, the shifting arm and an interlock member operatively connected to the shifting arm are interposed between the side plate portions of the interlock plate.

  • Patent number: 6725738
    Abstract: A gear shift apparatus for a manual transmission utilizes an actuator to prevent a miss shift manipulation from a forward gear stage to a reverse gear stage. The gear shift apparatus permits the driver to forcedly release a mis-shift preventing state with a smaller force. In the gear shift apparatus for a manual transmission, a select cam is responsive to a selecting manipulation to pivotally move to forward positions corresponding to forward select positions and a reverse position corresponding to a reverse select position. A restraint cam is driven to a prohibiting position by a plunger when a solenoid is energized to prohibit the select cam from pivotally moving to the reverse position. In this prohibiting state, as the select cam is pivotally moved toward a forward position in response to a manipulation for selecting a forward select position, a release protrusion of the select cam presses the restraint cam to pivotally move the same from the prohibiting state to a permitting position.
