An air duct system includes a first member that includes a groove disposed around only a portion of an opening. A second member defines a passage extending along a longitudinal axis, and is in fluid communication with the opening of the first member. The second member includes a flange disposed within the groove of the first member. The engagement between the flange and the groove restricts relative movement between the first member and the second member in an axial direction along the longitudinal axis. An attachment system connects the first member and the second member together, and restricts relative movement between the first member and the second member in a lateral direction that is transverse to the longitudinal axis, to secure the flange within the groove.

An air induction system for delivering equal quantities of combustion air to an internal combustion engine has an air box assembly comprising a housing that defines a filter chamber that is configured to receive an air filter assembly, an air inlet that admits the fresh air into the housing and the filter chamber and outlets extending from the housing. The air filter assembly further comprises a filter media disposed between the air inlet and the outlets to define a filtered air chamber on a flow side of the filter media and a partition extending across the filtered air chamber to divide filtered, fresh air passing through the filter media into two flow paths, the divided flows paths exiting the housing and the filtered air chamber through the outlets.

A shift control assembly and method includes a shift linkage, a shift control rod, and a retainer member. The retainer member is secured to the shift control linkage in a manner such that a fastener integral with the linkage extends through a portion of the retainer clip. The shift control rod is secured to the retainer by clip portions formed thereon in a manner such that a final assembly threaded member can be secured on the fastener member of the shift linkage to complete the shift control assembly. The assembly method involves providing a shift link with a fastener secured thereto, assembling a retainer on the shift link, assembling a control rod on the retainer, and securing the assembly together with a fastener member securely engaging the fastener secured to the shift link.

Shift linkage control assembly apparatus

A variable hysteresis module for use with an accelerator pedal with an electronic throttle control system for vehicles and the like includes a follower moveable along a back plate and urged by return springs against a cam actuator. The actuator acts against an angled side of the follower that resolves the pedal force on the actuator into a parallel component opposing the spring force and a normal component urging the follower against the back plate to develop friction that produces hysteresis. The hysteresis varies with the force of the return springs and so generally increases as the engine throttle is opened and decreases as the engine throttle is returned closed. If the spring force is reduced, the friction force is proportionally reduced. Other variations are also disclosed.

Pedal module with variable hysteresis

A remote control lever module comprising a shaft rotatably mounted on a support. A friction pad has a pair or surfaces each of which frictionally resists rotation of the shaft with respect to the support and permits relative rotation between the shafts and the support. A bearing assembly is loosely fit about the shaft to assure that the shaft may rotate in the support.

Remote control lever module

A remote control lever module comprises an inner shaft coaxially located inside an outer shaft. The inner and outer shafts are rotatably mounted on a support and can rotate with respect to one another. A return mechanism is engageable with the inner and outer shafts enabling forward rotation of the inner shaft to cause forward rotation of the outer shaft. The return mechanism further enables extended forward rotation of the inner shaft with respect to the outer shaft, and urges backward rotation of the inner shaft to a rearmost position. The return mechanism limits backward rotation of the inner and outer shafts beyond a nonactuating position. A force spring urges the outer shaft to the nonactuating position. Sensors produce electrical signals proportional to the angular position of the inner and outer shafts. A friction pad can be disposed between the inner shaft and support to frictionally resist rotation of the inner shaft with respect to the support.
