The research subject is an author’s design solution of a wheel transporter. Original structure of a powertrain, between an electric drive motor and a drive wheel, has been described in this work. A design solution of the powertrain shown in the work provides the ability to uncouple selected drive units and study of a motion trajectory in follower motion when the stub axles are immobilized. The consequence of the adopted solution is a specific distribution of contact pressures in a contact zone between the drive wheel and the ground, which is dependent both on a load of the platform, but primarily on whether a wheel is coupled to the drive unit and will be the follower system. This effect appropriately reflects both a resistance of the rotational motion of the drive wheel and the resistances associated with positioning of a steering system of the platform. The article describes the FEM model used in the analysis. Results obtained from performed research, contained in this publication will be used in developing analytical models with simulation studies about the four-wheeled mobile platform motion with taking into account a friction and a slippage.
