Abstract

One of the main means of increasing the cross-country ability of trucks should be considered to increase the coupling properties of their driving wheels with these surfaces, which can be implemented by special means that ensure the cross-country ability of the car in such conditions. Therefore, it is important to study the process of eliminating the slipping of a car wheel on an icy surface using a friction material. The article uses a mathematical model of I. M. Rabinovich to solve the problem of car wheel skidding and ensure the wheel’s adhesion to the icy road surface for different forms of the added layer of friction material. A device for adding coarse-grained friction material has been developed, which is installed on the machine’s subframe or on the chassis with the possibility of manual and automatic control for feeding abrasive material. Keywords: vehicle, device, coefficient of adhesion slip coefficient, sandblaster, stability, pneumatic wheel excavator, chassis, road surface, snow and ice formation
