  • Patent number: 10054217
    Abstract: In a shift lever device, when a lever is rotate-operated to an “R” position or a “D” position, a cushion of the lever abuts a stopper inside the housing, and the rotating operation of the lever is stopped. Note that when the lever is rotate-operated to the “R” position or the “D” position under a heavy load, a low rigidity plate and a low rigidity tube of the cushion undergo elastic deformation, and the high rigidity column of the cushion is sandwiched between the lever and the stopper. The rotating operation of the lever is thereby restricted. The high rigidity column is thereby able to effectively restrict the rotating operation of the lever.

  • Patent number: 6360627
    Abstract: An arrangement of an offset shift lever for an automotive vehicle transmission having a shift stub which is connected to the transmission and which also has a generally axial threaded bore. A metal cylindrical insert is sized to fit over the shift stub. The insert has a partially closed end with a fastener shank opening. An elastic isolator is bonded to the insert. The isolator has a fastener opening generally aligned with the fastener shank opening of the insert. A metallic canister encircles the isolator and is bonded thereto. The canister has a fastener opening and a shift lever opening. A shift lever is connected with the canister along its lower end which is received into the canister shift lever opening. The shift lever is aligned parallel and off-center to the shift stub by the canister. A threaded fastener is inserted through the canister and isolator fastener opening to threadably connect the shift lever canister isolator and insert with the transmission shift stub.

  • Patent number: 6212971
    Abstract: A vibration isolated shift lever comprises a control lever, a shift plate, a transmission plate, a transmission lever and resilient bushings located between the shift plate and transmission plate. The shift plate triangularly shaped and is provided with three shift plate apertures one being located at each of the apexes of the triangular shift plate. The transmission plate provided with a transmission lever receiver that is bolted to the transmission lever. The transmission plate is triangularly shaped and provided with three transmission plate apertures that are located at the apexes of the triangular transmission plate. The shift plate and the transmission plate are aligned so that the three shift plate apertures are lined up with the three transmission plate apertures. Three mounting bolts extend through the lined up shift plate apertures and transmission plate apertures. Each of the bolts is provided with a resilient rubber bushing.

  • Patent number: 6167773
    Abstract: Adjusting device for the automatic operation of a gear-change device with a shifting shaft associated with linear drives to introduce a rotational and a translatory movement. To convert an introduced translatory movement into a rotational movement, the linear drive provided to introduce rotational movement is actively connected to the shifting shaft by an articulated connection having two support elements that are urged toward each other by a prestress force and an articulated element actively connected in a force locking position between the two support elements by the prestress force.
