Abstract: Because a shift lever device 10 uses attracting force of a fixed iron core 150A, 216A of a magnet 150 or an electromagnet 216 in switching between a lock state and an unlock state at a shift lock mechanism 118 and a key interlock mechanism 200, the mechanisms can be made compact. When a shift lever 12 is changed from a “D” shift position to a “4” shift position and when the shift lever 12 is changed from a “2” shift position to an “L” shift position, a link 30 is rotated in a same direction. Thus, a sliding direction of a slider 38 which detects a rotational position of the link 30 is only one, and a placement size of a detecting member 48 can be made small and the device can be made compact. Because the shift lock unit 88 is equipped integrally with shift lock mechanism 118, and the link 30, the slider 38 and the detecting member 48 of a sensing mechanism, the shift lock unit 88 can be made compact.

Abstract: A mechanical gear shifting mechanism capable of connection to a gearbox includes a shifter frame and a rotatable shaft mounted to the shifter frame. A ratchet drum having teeth is fixed to the shaft. A first cam disc formed with a slot in its main face is fixed to the shaft for rotation therewith. A shifting lever is connected to the shifter frame and is pivotable about an axis in first and second directions. First and second engagement pawls are connected to the shifting lever and positioned for engaging the teeth of the ratchet drum, whereby pivotal movement of the shifting lever induces rotational movement about the shaft's longitudinal axis. A pendant lever is engaged with the slot via a follower and has an end engageable to the gearbox. In practice, the end of the pendant lever would be connected to gear selectors of the gearbox.

Abstract: The present invention is a dual-detent shifting apparatus, comprising a supporting seat, an actuating piece, and a detent piece. The supporting seat has plural cable-winding positioning slots and plural cable-releasing positioning slots.

Abstract: A manually operated transmission, for commercial vehicles having a plurality of synchronized forward gears and one unsynchronized reverse gear and optionally one unsynchronized crawler gear with synchronizer packets for the forward gears and locking plates, has a locking part (3) upon the gearshift bar (1) for the unsynchronized reverse gear or the gearshift bar for the unsynchronized crawler gear disposed in a manner such that when selecting the gate for the reverse gear or the crawler gear it engages without force in the adjacent gearshift bar (1) for one of the synchronized forward gears so that they are driven along in the shifting direction and thereby an ansynchronization of the forward gear adjacent to the gearshift bar (2) occurs, but a complete gearshift of the forward gear is prevented.

Abstract: A manually controlled transmission includes a combined detent and interlock pin mechanism. The elongated interlock pin prevents surrounding shift fork extensions from being engaged when a desired shift fork extension is selected. A recess in the interlock pin allows engagement of a shift lever with a desired shift fork extension, and opposing sides of the interlock pin engage shift finger notches in the other shift fork extensions to prevent their movement. Detent springs attached to the manually controlled transmission substantially contact opposing ends of the sliding interlock pin to provide resistance as an end of the interlock pin substantially contacts the detent spring. An anti-rotate pin positioned proximate to the interlock pin prevents rotation, but not translation, of interlock pin.

The shifter includes a base, and a shift lever pivoted to the base for movement between shift lever positions corresponding to the different gear positions. The shift lever includes a flange with an arcuate slot with a first enlarged pocket corresponding to a first one of the different gear positions and a second enlarged pocket corresponding to a second one of the different gear positions. An electromechanical device is provided having an extendable pin that is configured to engage the first enlarged pocket and lock the shift lever in the first one gear position until first predetermined vehicle conditions are met, and further that is configured to engage the second enlarged pocket and lock the shift lever in the second one gear position until second predetermined vehicle conditions are met.

Abstract: A shift lever apparatus comprises a shift lever connected to a gearbox of a vehicle, a rod integrally moved together with the shift lever within the shift lever due to shift-operation of the lever, a detent member having a detent hole formed therein, a restricting portion formed on the detent hole, and a base member supporting the shift lever in a pivotable manner. The shift lever, by being shift-operated to a predetermined shift position, changes a shift range to a predetermined shift range which corresponds to the predetermined shift position, among a plurality of shift ranges set at the gearbox. The rod has a projection portion toward an outer side of the lever and movable with respect to the shift lever due to a releasing operation. The projection portion penetrates and enters into the detent member located opposite the projection portion along a direction in which the projection portion moves as the lever is shift-operated. The restricting portion can be avoided by a releasing operation.

Abstract: In a selector device for a change-speed gearbox, a selector shaft arranged in such a way as to be rotatable and axially displaceable relative to a housing is connected by respective auxiliary mechanisms for converting a reciprocating motion into a rotary motion by at least two choosing sleeves that are arranged concentrically, rotatably and in an axially displaceable manner relative to it and are fixed rotatably and in an axially nondisplaceable manner relative to the housing when firmly braked by respective brakes. In significant angular positions, the selector shaft can be actuated out of a neutral position in one of the two axial directions of its axis of rotation into an end position associated with a respective gear. The auxiliary mechanisms are harmonized in such a way with one another that the respective new gear can be chosen initially and selected by external actuation of the selector shaft in just one direction of its axis of rotation and selective engagement of one, two or none of the brakes.

Abstract: A top cover assembly for a manual transmission is provided having a plurality of gears and a reverse gear. The top cover assembly comprises a shift rail assembly, a reverse biasing assembly, and a shift housing assembly. The shift rail assembly includes a sensing device that interacts with a contoured surface for producing a first electronic signal in response to the shift rail being in a neutral position for range shifting. Another contoured surface acts to center the shift rail and an operatively connected shift lever. For reverse biasing, the shift lever has a first lower shift force when moved to shift at least one of the forward gears. An interlock supported by the shift rail and shift sleeve rotates with the shift rail and acts to lock out other gears during a gear shift. In one aspect of the invention, the interlock is also used for reverse biasing. A detent engages the interlock for creating a higher shift force than the first lower shift force when the shift lever is moved to shift the reverse gear.

The member has ends which remain slidably received by housing sleeves so that the member cannot move transversely to its sliding axis. Part of the member engages the second shift member to prevent pivoting of the second shift member when the lever moves into engagement with the first shift member.
