Development of a New System for Attaching the Wheels of the Front Axle in the Cross-Country Vehicle

Abstract

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.

Determination of the Kinematic Excitation Originating from the Irregular Envelope of an Omnidirectional Wheel

“…This is due to many factors, most notably inertia. The design of the vehicle is also of great importance, as it influences the weight distribution and determines the suspension characteristics [ 28 ].…”

Experimental Research on Manson–Coffin Curves for the Frame Material of an Unconventional Vehicle

“…The optimization of the design consisted in adding telescopic struts to the original design ( Figure 2 ). A similar system of stabilizing the front wheel is used in practice for sports modifications of road motorcycles [ 30 , 31 , 32 , 33 , 34 ]. The choice of struts for this design is limited by the force expended by the driver.…”
