Abstract

Способ определения коэффициента сцепления поверхности дорожного покрытия, заключающийся в измерении параметров дорожного покрытия и вычислении коэффициента сцепления, отличающийся тем, что одновременно измеряются три величины: N - нормальная нагрузка от колес на дорожное покрытие; Pтяг - суммарная сила на рычаге тяги рулевого управления, возникающей при движении колес под углом к направлению движения транспортного средства и α - угол схождения колес управляемых колес, при этом коэффициент сцепления рассчитывается по формулеThe method of determining the coefficient of adhesion of the surface of the road surface, which consists in measuring the parameters of the road surface and calculating the coefficient of adhesion, characterized in that three values are simultaneously measured: N is the normal load of the wheels on the road surface; P-thrust is the total force on the steering linkage lever that occurs when the wheels move at an angle to the direction of the vehicle’s movement and α is the angle of convergence of the wheels of the steered wheels, and the friction coefficient is calculated by the formula
