Transportation operations occupy a large share of all types of work in the transport and technological support of agricultural enterprises of the Amur region, where the distance from the extreme western point of the region to the extreme eastern one is over 1 000 kilometers, and the distance between the southern and northern points is more than 600 kilometers. The main hypsometric features are elevation changes from 500 to 1 500 meters above sea level. In addition to the fact that the region has a large length of dirt roads, transportation operations in the region under consideration are also complicated by significant distances between settlements. It should also be noted that in a number of northern regions, cargo can only be delivered in the winter period on temporary roads that have a different surface of movement according to adhesion conditions and terrain features. All of the above features of the territory certain difficulties in the transportation of goods, since car operations are limited by the conditions of transverse stability. When driving on surfaces with a large angle of inclination, a sharp alternating redistribution of the weight load between the movers occurs. It leads to breakdown of the units and components of the undercarriage. One of the solutions to this problem is the introduction of technical devices that help to reduce the variable load on the movers. A promising technique, as studies show, can be a way to redistribute the weight in the chassis of the transport unit itself, which will increase the service life of the propulsion units and the efficiency of the vehicle. This article presents the research findings on improving the utilization efficiency of AWD vehicles of KamAZ brand for transporting cargo with the installed redistributing device «Frame load regulator», for which the Russian Federation patent No. 166665 has been obtained.
