  • Patent number: 4570440
    Abstract: An articulating type exhaust connector for a vehicle having a transversely mounted engine with an exhaust manifold moveable with respect to an exhaust header conduit caused by engine roll. The articulated connector includes a seating surface formed at the outlet of the manifold and a seal carried on the end of the header which engages the manifold. The end of the header and seal carried thereby is biased against the manifold by means of a flange and bolt connector and a washer type spring between the flange and the header so that the seal is pushed against the seat permitting the header and seal to articulate a substantial angular amount with respect to the manifold.

  • Patent number: 4165099
    Abstract: A suspension apparatus for the rear wheels of a motor vehicle includes a pair of control arms pivotally connected to the vehicle frame or body at one end and rotatively supporting the wheels by an improved structure which mechanically entraps a wheel spindle at the other end and a transverse torsion member extending between the control arms at a longitudinal position intermediate the ends. The torsion member is formed as a downward opening U-shaped channel member to position its shear center above the pivotal axis of the control arms to effect an understeer handling characteristic and is supported adjacent the control arms by gusset plates.
