Abstract

The working process of the car is accompanied by the coupling of the wheel drive with the road, which is regulated by the coefficient of adhesion, which leads to the movement of the compressed part of the tire (stretching of the tire and its compression, which leads to the dynamic movement of the rolling arm of the wheel drive of the car. The article deals with the study of the movement of the deformed part of the wheel tire engine of a car using the theorem on the change of kinetic energy of this system, the general equation of dynamics. The purpose of the research is to improve the theory of the technological scheme of the wheel drive load with the detection of the movement of the deformed part of the movement of the car wheel drive and the connection of this movement with the movement of the rolling arm of the car wheel drive and the influence of the output parameters on this connection. The scientific and practical direction of the work consists in the fact that for the first time a technology was considered in which, during the rotation of the wheel drive, the points of the deformed part of the tire of the wheel drive of the car are displaced and the Coriolis force appears, which significantly affects the coefficient of adhesion of the wheel drive to the road. The methodology of the study was to establish a mathematical relationship between the coefficient of traction of the wheel drive tire and the road. As a result of the study, it was established: the influence of the initial parameters and the surrounding environment on the deformed part of the tire of the car's wheel drive is reflected in graphic dependencies; a change in the speed of the deformed part of the tire of the wheel drive causes the appearance of Coriolis acceleration, and for the appearance of Coriolis acceleration, the authors proposed a formula for calculating the acceleration of the deformed part of the car tire; the degree of dependence of the size of the deformed part of the tire on the size of the shoulder of the wheel of the wheel drive was established, and this degree is negative. Keywords: Coriolis forces, Coriolis acceleration, rolling shoulder, deformed tire part, wheel drive.
