FIELD: transport.
SUBSTANCE: invention relates to automotive vehicles and is designed to improve the wheels bite with road surface, particularly, in running in ice-slick conditions. The device incorporates a loose material hopper with a guide chute, openings provided in the said hopper and furnished with a control column, an impeller and an agitator, an angular acceleration comparator and induction pickups, fastening slides. The impeller is driven by a gadget made up of a solenoid to feed compressed air from the receiver into the braking chamber with a rod pressing the drive shaft with a tightly fitted rubber roller against the running vehicle drive wheel, a bevel gear transmitting the drive rotary motion to the driven cardan shaft linked with the impeller.
EFFECT: higher cross-country capacity.
