【 摘 要 】

Vehicles with the 4WD system of different construction and functional solutions are offered by various manufacturing companies. Users of such vehicles expect continuous improvement of the efficiency in the field conditions while meeting at the same time the ecological requirements. Due to the high reliability and high efficiency in the field conditions the purely mechanical solution systems are often used. The article presents an analysis of the 4WD system operation which uses mechanical solution for torque distribution between drive axes. The tests were carried out on the MAHA LPS 3000 dual-axle chassis dynamometer using the registration of front and rear axle wheels driving forces and rotational speed values. During the experimental tests the vertical wheel loads as well as the tire pressures and the rolling circumferences were being changed. Analysis of the obtained results has served to make an efficiency assessment of the vehicle 4WD transmission system.
