A method for producing an over-running decoupler that is configured to transmit rotary power between a rotary member and a hub. The over-running decoupler includes a one-way clutch having a clutch spring, a carrier that is coupled to the clutch spring and at least one spring that resiliently couples the carrier to the hub. The method includes: establishing a desired fatigue life of the at least one spring; establishing a design deflection of the at least one spring during resonance, wherein deflection of the at least one spring at the design deflection during resonance does not reduce a fatigue life of the at least one spring below the desired fatigue life; and preventing resonance in the over-running decoupler by controlling a maximum deflection of the at least one spring such that the maximum deflection is less than or equal to the design deflection.

A shifter assembly for changing gears in a vehicle transmission including a housing, a shift lever, an emitter, a detector, and a link. The lever is pivotally mounted to the housing and is movable in a first gate along a first plurality of shift paths, and in a different second gate along a second plurality of paths. The emitter is spaced from the lever and is movable along a fixed path and the detector can determine a position of the emitter along the path. The link is attached to the lever and the emitter such that movement of the lever in either gate causes movement of the emitter along the path. The link is coupled to the lever and the emitter so to permit movement of the shift relative to the link during movement of the lever.

A cam mechanism for actuating a selector shaft, in particular for a single-motor gearshift actuation device, in particular to carry out a selecting movement of the selector shaft, comprising a cylindrical outer body having an inner circumferential surface and a cam track disposed on the inner circumferential surface and having an endless periodicity in a circumferential direction with at least one highest point and at least one lowest point, an inner body having at least one sliding guide extending in a direction perpendicular to the circumferential direction, at least one guide element disposed in the cam track and in the sliding and suitable for transmitting a movement of the guide element in a direction perpendicular to the circumferential direction to a selector shaft.

In a shift lever device, a gate pin of a lever is guided by a gate groove of a gate plate, and a detent pin of the lever is abutted on a detent face of a detent block due to an urging force. A sensor mechanism detects a shift position of the lever. The gate plate, the detent block, and the sensor mechanism are disposed at a lower side of the lever, the gate plate and the detent block are disposed at a rear side of the lever, and the sensor mechanism is disposed at a front side of the gate plate and the detent block. This thereby enables a reduction in size of the shift lever device in an up-down direction.

A gear absolute position sensor (GAPS) is provided. In some embodiments, a gear position sensor assembly includes a transmission shaft of a transmission, and a pair of magnets coupled to the transmission shaft. A first magnet of the pair of magnets may have a first magnetization direction, and a second magnet of the pair of magnets may have a second magnetization direction different (e.g., opposite) than the first magnetization direction. The gear position sensor may further include at least one magnetic sensor disposed adjacent the pair of magnets, the magnetic sensor capable of sensing three-dimensional motion of the pair of magnets and providing an output indicating movement, such as translation and rotation, of the transmission shaft. In some embodiments, each of the magnets is cuboid-shaped.

A transmission system for vehicles, including bicycles, is disclosed. The system aligns a chain or other drive means to a center of each of a plurality of provided sprockets, allows for a smaller, lighter and more durable shifter/controller, and reduces various complications associated with cable slack and shifting. A derailleur is provided with linear actuated features to directly translate drive means from one position to another along a desired path.

A clutch is provided that includes a fixed sheave portion, a movable sheave portion, a movable sheave assembly, an idler bearing and a torque drag member. The movable sheave assembly is configured to axially move the movable sheave portion in relation to the fixed sheave portion in response to a change in a rotational speed of the clutch. The idler bearing is rotationally mounted on a central post of the fixed sheave portion. The idler bearing is positioned to engage an inside face of a belt when the fixed sheave portion and the movable sheave portion are located a select distance away from each other. The torque drag member is operationally coupled to exert a select amount of torque drag on the idler bearing.

A target reaching rotational speed set during a torque phase is set to a value higher than an actual engine rotational speed, the value being higher as one of a vehicle acceleration and an engine rotational speed gradient is larger. That is, as the acceleration is steeper, the target reaching rotational speed is set to a value closer to an upper limit rotational speed or rotational speeds proximate thereto. Thus, a display rotational speed displayed on a tachometer at the end of the torque phase becomes high rotational speed. Accordingly, there is provided a display control device for a vehicle that enables a driver to feel the use of engine performance to the limit.

A transmission shifter assembly includes a shifter and a shifter bezel. The shifter includes a shifter body and a shifter handle movably coupled to the shifter body. The shifter bezel includes a bezel body and defines a handle opening extending through the bezel body. The handle opening is sized to partially receive the shifter handle. The shifter handle extends through the handle opening. The transmission shifter assembly further includes a plurality of locating features, such as shock absorbers, interconnecting the shifter bezel and the shifter body in order to align the shifter bezel relative to the shifter.
