Abstract

The goal of the paper is to provide breakaway of a motor vehicle from skidding with the use of friction material on public and toting roads.The development of an anti-skid device is reasonable because road services are not always able to maintain the proper road conditions due to overall highway mileage which leads to road icing and snow knurling, which in turn lowers the friction coefficient of tires with the road. Model analysis and practical experiments are carried out to model breakaway modes while using friction material. This process can be automated for the use in off-road vehicles with a dedicated device that will deliver large grained friction material. The mentioned device had been developed by the authors of the paper. A technical effect of increased adhesion coefficient is achieved within the research. This effect allows the increase in transportation reliability under difficult meteorological and road conditions on public and toting roads. Practical experiments showed that addition of large grain friction material when skidding modifies the surface in front of the tire into a segmented area (angled surface) that helps the vehicle to breakaway and move further without skidding.
