Features of torque transmission to drive wheels of vehicles

Abstract

For the development of the modern transport sector, it is important to study the processes taking place in nodes and mechanisms of force interaction. The automotive industry is a significant part of modern transport. The car's movement parameters largely depend on the interaction of forces arising at the point of contact of the leading wheels with the road. Automobile wheels work in complex elastic-stress and deformation conditions. Therefore, it is of particular interest to study the processes occurring in the zone of interaction between the driving wheel and the road. The most important factor affecting the traction force of vehicles is the way torque is transmitted to the driving wheel. Physico-mechanical characteristics of the tire material, friction force, methods of forming and transmitting engine power to the driving wheels, the relationship between traction force and power, rolling resistance - these and other factors that affect the efficiency and traction characteristics of road transport pose tasks to developers, which are difficult to solve.  The article considers some force aspects of the interaction of the driving wheel of vehicles with the road at the beginning of movement. The relationship between the traction forces and the load depending on the method of power transmission to the driving wheels is analyzed. Factors affecting the translational movement of the wheel have been identified. Experiments have been conducted that bring some clarity to the understanding of the essence of which method of power transmission to the driving wheels is more effective.
