    Abstract: A shift lever apparatus includes a base member, a shift lever, and one or more planar four-bar linkage mechanisms supporting the shift lever so as to be movable relative to the base member. The four-bar linkage mechanism includes four link elements including a base-side link element, a lever-side link element, and a pair of connecting link elements. The shift lever is supported by the lever-side link element, and the base member supports the base-side link element. The four-bar linkage mechanism includes an operational plane in which the four link elements conduct a link motion. The lever-side link element is parallelly or substantially parallelly shiftable in the operational plane relative to the base member so that the shift lever can shift parallelly or substantially parallelly in the operational plane relative to the base member.

    Abstract: A shifter assembly (20) having a base (22) and a transmission control member (30). A shift lever (36) is pivotally connected to the base (22) for movement within a first path (38) and a second path (40). The shift lever (36) is coupled to the control member (30) when the shift lever (36) moves within the first path (38) and is uncoupled from the control member (30) when the shift lever (36) moves within the second path (40). The shifter assembly (20) is characterized by a locking device (80) mounted to the base (22) for selectively engaging the control member (30). The locking device 80 remains stationary during the concurrent movement of the control member (30) and the shift lever (36) and moves into engagement with the control member (30) to couple the control member (30) to the base (22) when the shift lever (36) is in the second path (40).

  • Patent number: 6761084
    Abstract: A gate-type shift lever device in which a pin is formed at a mounting piece formed at a back wall portion of a base, which pin axially supports a plate switch. Two levers are formed at the plate switch. A shift lever abuts and presses one of the levers during a shift operation from a “D” position to a “4” position. The shift lever abuts and presses another of the levers, during a shift operation from a “2” position to an “L” position. In accordance with rotation of the plate switch due to the pressing forces received by the levers, a holder contact moves transversely. Thus, the shift operations from the “D” position to the “4” position and from the “2” position to the “L” position can be detected.

    Abstract: A manipulation lever can be manipulated to select a first mode for automatically changing the drive range of an automatic transmission or a second mode for changing the drive range by manually manipulating the manipulation lever. The manipulation lever is shifted between the first mode in which a control lever moves mechanically with the manipulation lever and the second mode in which the control lever does not move with the manipulation lever. A first guide portion guides the manipulation lever and a second guide portion guides the clutch lever. When the manipulation lever is arranged at the drive position, the first and second guide portions permit the manipulation lever to be disengaged from the clutch lever. When the manipulation lever is arranged at positions other than the drive position, the first and second guide portions keep the manipulation lever to be engaged with the clutch lever.

  • Patent number: 6397698
    Abstract: The present invention intends to provide a controlling device for transmission in which locking action of the locking mechanism is not hindered by a part of the controlling device such as an actuator, when a fork shaft as an operating mechanism is held at a neutral position. For such purpose, the controlling device for transmission includes plural fork shafts, a selecting member selectively engaging with one of the fork shafts, a selecting actuator for moving the selecting member to engage with the fork shaft, a shifting actuator for applying load to the fork shaft engaged by the selecting member, and locking mechanism for locking the fork shafts. In such controlling device, the selecting actuator is constructed to move the selecting member to a non-engaging position not engaging with any of the fork shafts.

    Abstract: A shifter includes a base and a shift lever pivoted to the base for movement along a single planar shift path. The single planar shift path includes a first portion having P, R, N, and D (i.e. an automatic-shift mode) and a second portion with 4, 3, 2, and 1 (i.e. a manual shift mode). A switch on the shift lever operates a solenoid for changing between an automatic shift mode where the first portion is operable, and a manual shift mode where the second portion is operable. A shift lever position indicator indicates a position of the shift lever in all its positions. The shift lever position indicator includes first and second polarized screens and a first and second polarized light sources arranged to selectively illuminate the first and second indicia when the shift lever is in the automatic or manual shift mode.

  • Patent number: 6260432
    Abstract: A selecting device facilitates selecting operating positions of an automatic transmission of a motor vehicle by the deflection of a selector lever which moves back automatically from all deflecting directions for selecting the individual operating positions. The automatic transmission can be controlled by this selector lever in a first operating mode—selecting individual driving positions in the automatic operation—or, in a second operating mode—step-by-step shifting of the gears in the manual operation. For each operating mode, one operating position of the automatic transmission respectively is assigned to each deflecting direction of the selector lever. The selector lever is movable, in two shifting channels which are essentially disposed perpendicularly with respect to one another such that maximally four operating positions can be selected in each of the two operating modes. In a third operating mode, cruise control functions can be controlled by means of the selector lever.
