Abstract: A linear actuator includes a reversible electric motor which drives a spindle via a reduction gear with several stages and an activation element connected with it, and an overload clutch in connection with the first stage or one of the first stages in the reduction gear. This is advantageous in terms of structure and load and greater flexibility is achieved in the construction of the structure.

Abstract: An actuator has a rotatable input member coupled to a drive member such that rotation of the rotatable input member under an input load causes rotation of the drive member on a first axis. The drive member is coupled to a driven member such that rotation of the drive member causes rotation of the driven member on a second axis which is laterally offset from the first axis. A coupling between the drive member and the driven member is arranged to provide a rotational reduction from the drive member to the driven member. The driven member is arranged for connection to a wire of a Bowden cable having a sleeve seatable in relation to a housing for the actuator such that rotation of the driven member causes extension or retraction of the cable.

Abstract: A pedal assembly including a pedal support and a pedal member rotatably coupled to the pedal support to allow pivotal movement of the pedal member about a pivot axis. The pedal assembly further includes a friction member having a bearing surface, and a clamp member engaged with the pedal member and having an engagement surface abutting the bearing surface of the friction member to define at least two separate and distinct surface contact regions. The pedal assembly also includes a biasing member arranged to bias the clamp member to provide frictional engagement along the separate and distinct surface contact regions to resist pivotal movement of the pedal member. In one embodiment, the clamp member is engaged with the pedal member by a sliding pivot configured to allow the clamp member to be pivotally and slidably displaced relative to the pedal member during pivotal movement of the pedal member.

The power transmission is constructed of a rotation shaft having a thread formed on a periphery thereof; a nut member capable of being opened and closed, the nut member having a thread engaged with the thread of the rotation shaft, and pinching the rotation shaft and moving as the rotation shaft is rotated; a regulating part enabling movement of the nut member by regulating opening of the nut member; and a regulation releasing part capable of releasing engagement between the nut member and the rotation shaft by opening the nut member.

Abstract: An adaptive position kick-down detent mechanism for providing a force feedback to an operator of a vehicle through a drive-by-wire accelerator prior to the transmission performing a kick-down. The kick-down detent mechanism includes a plunger portion, a plunger driving device, and an elastic portion. The plunger portion is slidable within the plunger driving device and is biased by the elastic portion. An electronic control unit communicates a kick-down pedal position to the plunger driving device, which moves the plunger portion to the kick-down pedal position so that the force feedback is provided to the driver before the kick-down even as the kick-down pedal position changes during vehicle operation.

Abstract: A drive system for rotating an assembly, such as an external vehicle mirror housing, about an axis is provided with a drive housing containing a worm drive assembly coupled to an axis gear mounted about the axis. The worm drive assembly is rotated by an electric motor. The axis gear is stationary with respect to the axis, such that rotation of the worm drive assembly will cause it to travel about the axis gear. Such movement of the worm drive assembly will cause the drive housing and the associated external vehicle mirror housing to rotate about the axis. Thrust transmitted to the worm drive assembly is transmitted to a central portion of the drive housing by a shaft retainer associated with the worm drive assembly. Play between the axis gear and the worm drive assembly is prevented by eliminating separation between adjacent components of the worm drive assembly.

Abstract: The present invention broadly comprises an assembly for incrementally changing an axially fixable position, including an annular gripping element with at least one deformation segment, a glide push ring axially displaceable along a pilot element, and a wedge push ring axially displaceable along the pilot element. The gripping element is in contact with a circumference of the pilot element and the deformable segments are circumferentially deformable in response to a change in a gripping element diameter. The glide ring incrementally urges the gripping element in a first direction along the pilot element. The gripping element axially fixes responsive to force applied by the wedge ring in a second direction, opposite the first direction, along the pilot element. A surface between gripping element inner and outer circumferences forms a fixed angle with the pilot element despite changes in the inner or outer circumferences.

Abstract: A motorized anti-backlash linear actuator comprises a motor; a hollow shaft that is rotated about a central axis by the motor, an anti-backlash nut that is nested at least partially inside the hollow shaft; and an externally threaded rod or lead screw that engages with the anti-backlash nut such that the rotation of the hollow shaft and the nut imparts a linear motion to the rod that is substantially free of backlash. Nesting the anti-backlash nut at least partially within the hollow shaft provides greater stability to the actuator, and permits high speed operation.

Abstract: A mounting system is disclosed for mounting a bearing assembly or other mechanical element to a shaft. The mounting system uses a tapered sleeve mechanism to secure the bearing assembly on the shaft. Specifically, a pressure loaded piston drives the sleeve from a pre-assembled position to an initial position. The initial position is determined by monitoring the pressure applied to the piston. Once the initial position has been reached, a linear indicator is used to measure the axial sleeve movement from the initial position to a final position. The system remains in place after the bearing is installed on the shaft and facilitates removal of the bearing assembly from the shaft.
