Abstract

The work is devoted to the problem of negative dynamic effects on the transmission and the engine of a mobile vehicle on ultra-low pressure tires. When using this propulsion device on technological means, the load on wheel reducers (final drives), half shafts, differential, final drive, on the shaft and cardan drive hinges, spline connection, transfer case, elastic transmission clutch, transmission drive and driven shafts sharply increases with gears, clutch driving and driven parts, engine crankshaft. When the load on these elements is excessive, their service life is reduced, and excessive loading can even lead to a sudden failure. Since each of these nodes is somehow fixed on the frame of the vehicle, to which vibrations from the unevenness of the rolling surfaces perceived by the propulsion are transmitted, they also have an additional effect. For a comprehensive assessment of the dynamic loading of the transmission and the engine of a mobile vehicle equipped with ultra-low pressure tires, taking into account the influence of road irregularities, a mobile vehicle model was compiled. The model will allow a more accurate calculation of the basic characteristics of technological equipment transmissions on ultra-low pressure tires.
