  • Axle pivot steering device of a vehicle
    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.
