Abstract: A shifting mechanism and method of using the shift mechanism is described. The shifting mechanism has a shift fork. Flanges are connected to a portion of the shift fork. Pin apertures in the flanges receive pins therein. The pins are connected to a block, which receives a screw gear therein. The screw gear is connected to a shift motor.

Abstract: A shifting mechanism has a shift fork. The shift fork has upper and lower arms connected by an upright portion. The upright portion defines a pivot axis for the fork. The mechanism also has a clutch collar that is connected to the shift fork. The shift fork is connected to gearing and a motor to pivot the fork and thus the clutch collar into and out of engagement with a clutch.

Abstract: An assembly includes a rotary joint spindle and a rotary joint body rotatably disposed on and in fluid communication with the rotary joint spindle. The rotary joint body is housed by a hub cap and provided adjacent an end of a spindle. A pressure relief valve is disposed between the hub cap and the rotary joint body. The pressure relief valve selectively provides a seal between the hub cap and the rotary joint body.

Abstract: The present invention relates to an independent rear vehicle suspension that comprises a fore/aft link with first and second ends, where a bracket pivotally supports the first end of the fore/aft link from a vehicle frame member. The fore/aft link has an air bag spring located between the fore/aft link's second end and the frame member. A lateral link pivotally connects between the fore/aft link's second end and the vehicle frame. A wheel upright, with an axle aperture extending through it, is rigidly attached near to the second end of the fore/aft link and located above the fore/aft link. An upper control rod is pivotally connected to the wheel upright and pivotally mounted to the frame member.

Abstract: A lightweight vehicle frame capable of bearing significant loads is provided. The vehicle frame includes first and second rail members extending parallel to one another and at least one cross-member extending between the first and second rail members. At least one of these members includes adjacent apertures in a side wall. One of the apertures is larger in size proximate one edge of the side wall than an opposite edge of the side wall. The other aperture is complementary in shape and is larger in size proximate the opposite edge of the side wall than the one edge of the side wall. The resulting structure reduces the weight of the vehicle frame, yet maintains significant load-bearing capabilities.

Abstract: An integrated system for automatically controlling the operation of both an automated manual transmission and a multiple speed axle assembly in a vehicle drive train assembly includes a transmission actuator for operating the transmission in any one of a plurality of transmission gear ratios. The system further includes an axle actuator for operating the axle assembly in any one of a plurality of axle gear ratios. An electronic controller is provided for operating the transmission in a desired one of the plurality of transmission gear ratios and for operating the axle assembly in a desired one of the plurality of axle gear ratios to provide a desired overall gear ratio for the vehicle. To accomplish this, the electronic controller is responsive to one or more input signals that represent operating parameters of the vehicle.
