Abstract:

In the article stated the definition of dependency of optimal number of axes of mountain self-propelled chassis. Is defined the relationship between the characteristics of soil index and relative resistance of soil at compaction during wheel pass-back in one track. Also is defined coefficient of adhesion of chassis wheel with a deformable soil. Are defined the dependence of the change in rolling resistance coefficient on the number of axles and influence of the pressure value of the wheels on the specific index of cross-country ability.
