FIELD: transport engineering; tractors.
SUBSTANCE: invention relates to wheeled tractors equipped with automatic power regulator of mounting system, namely, to devices for increasing cross-country capacity and efficiency of wheeled tractors geared with two-axle trailers. Proposed device contains main power coupling of trailer pole with tractor and hydraulic mounting system whose lift levers are coupled with trailer front axle through crossmember and flexible element. Hydraulic mounting control system includes driving wheels slip pickup whose signals are transmitted to drive of spool of tractor mounting system regulator, and electromagnetic to control said spool.
EFFECT: reduced slipping of driving wheels on sections of road with low wheel-road adhesion coefficient.
