  • Patent number: 7617907
    Abstract: An axle pivot steering device (4) of a vehicle having first lever elements (8A—1, 8B—1), which are respectively operatively connected, via a second lever element (8A—2, 8B—2), with a wheel carrier (10A, 10B). The first lever elements (8A—1, 8B—1) and the second lever elements (8A—2, 8B—2) are connected with third lever elements (13A, 13B), in an articulated manner, at fixed rotational points (14A, 14B). At least two of the lever elements (8A—1, 8A—2, 13A) are designed to be fork-shaped and be inter-coupled, in an area of the rotational points (14A, 14B), by a bearing bolt (15) such that the bearing torques resulting from the bearing forces acting on the bearing bolt (15) are at least approximately zero.

  • Patent number: 7201530
    Abstract: An adjustable torque rod comprising includes an adjusting sleeve, a housing and a rod. The adjusting sleeve includes a center surface, a first end and a second end. The housing has a receiving end that is rotatably connected to the second end of said adjusting sleeve. An attachment end of the housing, opposite the receiving end, includes a bushing for use in connecting the housing to a vehicle. A clamp is positioned proximate the receiving end for fixing the adjusting sleeve into a position in the receiving end of the housing. The rod has an adjustment end and a mounting end. The adjustment end is rotatably connected to the first end of the adjusting sleeve. The mounting end, opposite the adjustment end, includes a bushing for use in connecting the rod to a vehicle. The torque rod is extended and retracted by rotation of the adjusting sleeve.
