DEVELOPMENT OF AN EXPERIMENTAL SETUP FOR STUDYING THE EFFECT OF LOW TEMPERATURES ON THE PERFORMANCE OF POWER STEERING UNITS

In this article, the object of the study is the hydraulic steering system of a truck. Based on the results of the experimental studies, it was proposed to use local heating of the steering mechanism of vehicles equipped with a hydraulic power steering. An experimental setup was assembled and the dependence of the temperature regimes of the hydraulic power steering on its performance and reliability was derived. The possibility of maintaining the operability of the hydraulic steering mechanism under low-temperature operating conditions by using local heating using an electric or volumetric heater has been proven.
