FLOW CHARACTERISTICS FORMATION OF POWER STEERING WITH ROTARY DISTRIBUTOR
Abstract
In order to obtain an adequate mathematical model of vehicle hydro-mechanical steering which is equipped with a steering mechanism combined with power steering and a rotary distributor it is initially necessary to get current consumption values in the units of hydraulic scheme which are determined by dynamic changes of flow passages of pressure and drain circuits according to turning angle of the distributor. Such characteristics are usually determined experimentally.
The paper proposes a sequence which is recommended for determination of consumption characteristics which is formed with due account of multi-directional kinematic perturbations, mechanical clearance, possible emergence of hydraulic backlash and desired throttling law.
The factors account makes it possible to obtain an acceptable mathematical analogue of a hydro-mechanical steering for execution of robust investigations.
