In this study, a novel kinematic analysis procedure of the double wishbone suspension mechanism regarding steering input is proposed. In the previous study, published by the authors, the double wishbone mechanism was investigated disregarding steering input. To the best of our knowledge, there is no analytical method available in the literature for the analysis of double wishbone suspension mechanism regarding steering input. Initially, analysis of the mechanism for variable steering input, while keeping wheel travel fixed is considered. Then, kinematic analysis is performed analytically for the ultimate case of two inputs. Analysis simultaneously for both variable steering and variable wheel travel is presented. The essential parameters; camber, caster, kingpin angles are defined according to the kinematic model. For verification, a synthesized mechanism is established in Catia software and same results with the analytical model are obtained. Another presented novel analytical approach is anti-dive/lift analysis of the double wishbone mechanism.
