Abstract: A steering assembly is provided for a vehicle including an upper connection, typically provided by an upper control arm. A knuckle includes an upper and lower portions with the upper portion supported by the upper connection. A lower assembly of the present invention includes a control arm with legs extending from a spring portion at spaced apart ends. The legs extend from its ends and converge to a lower connection for supporting the lower portion of the knuckle with the upper and lower connections defining a wheel camber and a wheel caster. Preferably, each of the legs of the control arm has a different spring rate to provide a change in wheel camber under the deflection of the control arm during wheel travel. The different spring rates of the legs permits the lower connection to twist thereby enabling the wheel caster to change slightly during the upward and downward motion of the wheel.

Abstract: The invention provides a wheel suspension for a vehicle, wherein both a right wheel and a left wheel are carried by a linkage having a first end section and a second end section. The first end section is connected to the vehicle on the opposite side of the vehicle in relation to the respective wheel, and the second end section is likewise connected to its respective wheel. The invention is particulary significant in that the linkages are substantially U-shaped. Each linkage has two legs which are mainly parallel and extend in a substantially transverse direction of the vehicle. The free ends of the linkages constitute the first end section. The linkages also have a closed section connecting the legs. This closed section constitutes the second end section, whereby an open space is defined between the legs of each linkage. At least one leg on one of the linkages extends into the open space between the legs of the other linkage.

Abstract: In order to limit rolling movements of the vehicle, spring arms are formed on those ends of the leaf spring, arranged transversely to the vehicle, on which the wheel carriers are articulated, said spring arms being connected in a force-transmitting manner to the transverse leaf spring. The spring arms point toward the longitudinal mid-plane of the vehicle and run at an acute angle to the transverse leaf spring. Since the spring designed in this way is a universally available structural part (the spring arms running at an angle may also be produced separately and then be connected non-positively to the transverse leaf spring), the two wheels are connected to one another directly and the triangular shape formed by the spring arms running at an angle gives rise to a function similar to that of a transverse link.

Such arrangement facilitates manual height adjustment of the vehicle suspension.
