In the introduction of this article the authors deal with a general overview in the area of suspending the wheels of the road vehicles. It is important for creating an original design and this is the core of the operation. The implementation of the design to a real vehicle created a space for modifying this design. The necessity of a modification shows important especially after the MKP analysis of the original design. Currently the Industrial Property Office of the Slovak Republic grants the presented design solution the rights for protection as a utility model. For granting the protection it was not necessary to prove the safety parameters of the design. However, the possibilities of the real utilisation are fully dependent on the safety conditions. Therefore, the research process presented in this article is necessary for building a prototype of this system. As the area is relatively extensive, it was necessary to divide it into several parts. The design and its importance for the industry are presented in the first part. The second part deals with analytical calculations and numerical simulations of the quasi-static loading of the structure. Furthermore, the article considers the kinematic and dynamic area of the vehicle. The authors also deal with the sensitivity analysis of the change of the wheel camber. This simulation is realised by the programme Altair Motionview for the vertical motion of the front axle through the presented design.
