Rassokha V.I., Isaychev V.T. FEATURES OF DETERMINATION OF PARAMETERS OF THE LAG EFFECT OF SYSTEM OF AUTOMATIC CONTROL OF THE CONVERGENCE OF THE OPERATED CAR WHEELS AT DYNAMIC OVERCOMING OF RISESAt the movement of the vehicle under the influence of various factors because of gaps and deformations in elements of the steered bridge and a steering constantly there are uncontrollable changes of a camber and convergence of steered wheels leading to increase of resistance to the movement, wear of tires and fuel consumption. Authors developed and patented system of automatic regulation of a convergence of steered wheels of the vehicle in the course of the movement. As criterion of an assessment of correctness of a convergence of steered wheels of the vehicle equality of the lateral reactions of the same name of the road to steered wheels at an in-line motion on the horizontal road is accepted. The analysis of the parameters having impact on process of regulation of a convergence of steered wheels of the vehicle in the movement is carried out. The interrelation between parameters of the system which is carrying out such regulation and a condition of the vehicle is established. The offered system is mechanical system, therefore, possesses inertia. Therefore if there was a violation of a convergence of steered wheels of the vehicle and it is necessary to restore it by force of operation of the executive gear of system, this force needs to be terminated earlier, than steered wheels of the vehicle will reach the correct situation, and further wheels will reach their correct situation due to inertia of system. In the previous articles of a cycle four cases of the movement of the vehicle — uniform are considered, at dispersal, braking and coasting. In this article the case of dynamic overcoming by the vehicle of rises is considered. The received theoretical dependences allow to determine rational parameters of system of automatic regulation of a convergence of steered wheels of the vehicle in the movement which will allow to reduce wear of tires, resistance to the movement and fuel consumption.Key words: the vehicle, a convergence of the operated wheels, system of regulation, a lag effect, dynamic overcoming of rise.
