Design of automotive constructions based on interior and body outfit of offroad car

Travelling off the road requires an adequate vehicle. The basic car needs to be properly chosen and prepared according to its destination. Due to understanding problem, the paper explains differences between various kinds of four-wheeling like extreme passage rally, time race or just off-road expeditions. The paper contains classification and description of the most popular in western Europe terrain cars, their construction solutions and general advantages and disadvantages. In the document are also presented vehicle selection criteria. This issue is as significant as proper choice of adequate driving type. Established criteria relate to variety and power of engines, four wheel drive, reduction gearbox, differential locks, weight, and the most important geometric and operation parameters. Due to above features is made the comparison and choice of car for further development. The review, evaluation and selection of building elements are customized to chosen car. Project of development of interior contains construction assumptions, strength calculations and numerical model of the drawer located in the rear of the luggage. Additionally there are also drawings of arrangement of particular body elements. Graphical model, drawings and strengths calculations are performed using the Autodesk Inventor Professional 2011 and AutoCAD Mechanical 2011. Just as the chosen equipment, project is adjusted to dimensions of luggage area of chosen car. Author’s design includes original spacing between the openings in exterior, what allows embedding drawer without any interference in the car body.
