ADAPTIVE SYSTEM FOR INCREASING CROSS-COUNTRY CAPACITY OF SNOW PLOW WHEEL ROAD TRAIN Russian patent published in 2019 - IPC B60B39/00 

FIELD: machine building.

SUBSTANCE: invention relates to transport machine building and can be used for increase of cross-country capacity of snow-plow road train, which includes car with snow-clearing blade and trailer. Device comprises pneumatic system, control element of which is valve made structurally on snow plow. Valve is connected by means of pipelines to the pneumatic cylinder pivotally installed on the tow bar and trailer body. During performance of snow-clearing works, at moment of dump stop in snow-ice mass, and, as a result, slippage of road-train, car raid takes place on snow-removing dump, wherein valve is opened and air from pneumatic braking system is supplied to above-piston space of pneumatic cylinder. As the pressure increases, the piston moves downward, the rod acts on the trailer of the trailer, which, in its turn, unloads the trailer front axle and loads the driving wheels of the car.

EFFECT: increased cross-country capacity of snow-plow road-train at performance of snow-clearing works.
