  • Publication number: 20150321693
    Abstract: The present invention relates to a steering arrangement, a restoring part and a steering system, that includes a tie bar unit, an actuating unit and a lever element, the lever element being fixed in a pivotable manner at a first turning point immovably disposed in a reference system, wherein the actuating unit has a restoring part, an active part and a damping part and is secured against displacement along a transverse axis relative to the reference system, at least one of the parts exerting a force on the tie rod unit to displace the tie rod unit along the transverse axis or to secure it against displacement, wherein the tie rod unit is pivotably fixed at a second turning point on the lever element and therefore displacement of the tie rod unit along the transverse axis leads to a pivoting movement of the lever element about the first turning point.

  • Patent number: 6651995
    Abstract: An axle suspension for air-suspended utility vehicles and the like with which the vehicle chassis is supported by a pneumatic spring. The spring is configured as a plunger piston assembly, is preferably cylindrical, and has a plunger piston (6) that is provided for supporting and guiding a pneumatic spring bellows (5). The pneumatic spring bellows is connected via an upper mounting plate (7) to the vehicle chassis resting thereupon and is connected, e.g. via a lower base plate to the top of the plunger piston which is supported, for example, on a leaf spring assembly (1).
