  • Patent number: 10641382
    Abstract: A shift control device for an automatic transmission comprises a shift control member configured for manipulation by an operator to control a shift mechanism of a vehicle transmission, and an artificial feel mechanism coupled to the shift control member for providing tactile feedback. The artificial feel mechanism comprises a sensor, a controller, and a piezoelectric element. The sensor is configured for detecting a position of the shift mechanism and sending a signal that is indicative of the position. The controller is configured for receiving the signal, determining a control voltage, and providing the control voltage to the piezoelectric element. The piezoelectric element is configured and arranged so as to receive the control voltage and to apply a mechanical force that depends upon the control voltage and that is configured and applied so as to mechanically resist movement of the shift control member relative to the shift control bracket.

  • Patent number: 8448987
    Abstract: A steering column assembly has an outer jacket extending, an inner jacket is slideably disposed in the outer jacket for telescoping movement relative to the outer jacket, and a sleeve disposed between the inner and outer jackets. The sleeve exerts a predetermined frictional force on the inner jacket opposing the telescoping movement. A filler formed from a liquid thermosetting composition is disposed between the sleeve and the outer jacket for securing the sleeve to the outer jacket. Furthermore, a method of forming the steering column assembly includes disposing the inner jacket into the outer jacket and disposing the sleeve between the inner and outer jackets. The method further includes inserting the liquid thermosetting composition into the outer jacket between the outer jacket and the sleeve and curing the liquid thermosetting composition to form the filler.

  • Patent number: 8127639
    Abstract: A telescopically collapsible vehicular steering column assembly includes inner and outer shaft tubes which are joined in a sliding fit by a bushing. The bushing includes a pair of spaced journal bearings formed of steel-backed PTFE held in a plastic carrier body. The bushing is located in a receiving chamber in the outer shaft tube. A clearance compensator reacts against the receiving chamber to exert a radial compressive force through the carrier body and the journal bearings to improve the sliding fit with the inner shaft tube and remove lash. The clearance compensator can take any form, such as a hollow annular rib, a skirt with a flexible free end, or an array of nubs carried in thinned sections of the carrier body. The clearance compensator in all of these variations operates within a clearance space and has dimensional attributes which can be changed during the design and manufacturing phases of the bushing to optimize a characteristic of the steering column assembly.

  • Patent number: 8033738
    Abstract: A bearing assembly is provided including at least one needle roller that is resiliently compressible in response to a load applied to an exterior surface thereof. In addition, a method is provided for taking up a clearance between one or more first rollers and a bearing race in which the rollers are positioned. At least one resiliently compressible second roller is provided rollably secured within the bearing. The compressible second roller has an outer diameter greater than an outer diameter of any of the first rollers, such that the compressible second roller resiliently compresses when the bearing is positioned in the bearing race. Forces generated by compression of the resiliently compressible second roller urge the first rollers against a surface of the bearing race, thereby taking up the clearance between the first rollers and the race.
