Automobile chassis is an important part located between the vehicle loads and its wheels. This article gives a calculation technique of the reaction forces on the wheels for the vehicles which have more than two axles in static steady case. The paper takes the refection of the ways of distributing the loads on the wheel reaction forces values. The study has two groups; the first group has four models of the chassis analysis deference the concentrated points of goods-load distribution. The second group has three models of the chassis analysis differentiation the truck supporting places. The paper reviews the most important research works which have been published in the years period (2005-2015).The results of reading this paper will give the researcher summary of a recent technique in the field of calculate the vehicle wheels reaction forces. These calculations are related to the values of the truck’s loads and their places using their forces, moments (Clapeyron’s theorem of three moments) equilibrium equations analysis and MATLAB package.
