FIELD: transport.
SUBSTANCE: invention relates to motor vehicles and is intended to increase wheel adhesion to slippery road. The device includes container for abrasive material (10) storage in the form of vertical tubes (1) installed behind vehicle cabin (2), device for abrasive material feeding in the form of horizontal-oblique tubes (3) and guiding chutes (5). At the beginning of each horizontal-oblique tube (3), feeding conveyor (4) is installed, and in the guiding chute (5), grinder (6) is installed. Bottom end of the grinder (6) can be installed in front of driving wheels (9) or enter a hole in fender (8) above driving wheels (9), and part of horizontal-oblique tube (7) is made flexible. Spheres of 10-150 mm in diameter are used as abrasive material for prevention of vehicle driving wheels slippage.
EFFECT: elimination of abrasive material adfreezing and caking, higher reliability of spheroidal abrasive material transportation to grinder and getting of grinded abrasive sphere under vehicle driving wheels.
