  • Axle shaft assembly
    Patent number: 9045001
    Abstract: An axle shaft is fabricated from two separate pieces. The axle shaft is comprised of an axle shaft body having a forged initial flange portion formed at one end. An axle shaft flange, fabricated by stamping or casting for example, is secured to the forged initial flange portion at a weld interface to form a finished axle shaft.

  • Method for welding a differential housing
    Patent number: 6744004
    Abstract: A method of welding an axle housing surface to a blank surface includes generated heat in one of the two components. Heat is generated from at least one of these surfaces at their interface sufficient to weld them together. The surfaces are then applied together.

  • Composite torsion bar
    Patent number: 6431531
    Abstract: A vehicle suspension assembly is provided that includes a vehicle frame. A suspension member is pivotally supported on a portion of the frame. A torsion bar having a longitudinal axis and first and second opposing ends is supported between the vehicle frame and a suspension member by its ends. The torsion bar is twisted about the longitudinal axis in response to the suspension member pivoting relative to the frame. Resin coated reinforcing fibers are secured to the exterior surface of the torsion bar at an angle relative to the longitudinal axis. The torsion bar may be hollow to reduce the weight of the torsion bar. The resin coated carbon fibers are cured to the exterior surface by an oven or by induction heating.
