A new approach to assessment of vehicular traction dynamics

Abstract The work shows the inaccuracy of the statement that the traction moment on the traction wheel is an internal force and the tangential reaction on this wheel is an external force. The author proves that the rolling resistance moment of the vehicle wheels is an internal force, and the losses caused by this moment should be covered by the transmission efficiency factor. The paper revises the equation for traction dynamics of the translational motion of a vehicle, which can be used in the analysis of its traction-speed properties.
