Abstract
Abstract In wheel suspensions of automotive vehicles, equipped with a wheel suspension system comprising a coil spring, a specific mutual association is required for functional reasons for the individual components of the wheel suspension, forcing constructional compromises in connection with the other structural conditions inherent in the design of the vehicle. In order to be able to avoid in such cases expensive compromise solutions, it is disclosed to have one or several vehicle components, to be correspondingly correlated with the coil spring, project in between turn portions of a spring turn that has a larger lead as compared with the regular lead of the coil spring, or pass such components through the expanded spring section of the coil spring.
