A spatial model of interaction between a wheel vehicle and a road surface was considered in this article. Expressions for kinematic and power factors that determine motion and oscillations of a wheel vehicle, transmission elements and its running gear under spatial loads were obtained. It was shown that specifying wheels displacement in the coordinate system connected with the vehicle’s body allowed to make this mathematical model of motion significantly more precise. This approach provides a possibility to obtain a reliable estimate of exploitation operating modes of aggregates and systems of a wheel vehicle under conditions of passing engineering constructions.
