Abstract

In order to identify the reasons for the decrease in the efficiency of vehicles equipped with traditional suspension designs and to identify promis-ing areas for improving their efficiency, an analysis was made of the results of a review of studies obtained in the scientific field under consideration by foreign and Russian scientists. The article substantiates the relevance of increasing the efficiency of suspensions of specialized trucks and road trains operated in difficult changing climatic and road conditions. The main disadvantages that appear during the operation of vehicles equipped with traditional suspension designs are given. The consequences of the operation of such vehicles equipped with traditional suspension designs in conditions of a low level of road infrastructure are listed. The advantages of hydropneumatic suspensions, leaf springs made of composite materials in comparison with steel springs, independent suspension structures over dependent ones, semiactive air suspensions over passive and active ones, as well as regenerative suspensions are considered. The dependences of the change in the time between failures of the elements of the spring suspension, the estimated durability of the spring on the speed of movement, the acceleration of the sprung mass of the trailer of a road train when driving over bumps, the resistance forces of the hydraulic shock absorber on the ambient tem-perature are presented. The dependences of the change in natural frequencies and the damping coefficients of oscillations of the sprung and un-sprung masses of the car with an increase in the mass of its sprung part are given. The perspective directions for increasing the efficiency of suspensions of timber trucks and road trains identified as a result of the analysis are given.
