transport engineering; vehicles with higher load on steerable axle. SUBSTANCE: proposed device has two hydraulic circuit consisting of hydraulic pumps 1 coupled with hydraulic distributors 2 by pressure main lines 3. Hydraulic distributors 2 are coupled by main lines 4 with power cylinders 5 and by drain main line 6 through filters 7 with expansion tanks 8 which, in their turn, are coupled with hydraulic pumps by suction main lines 9. Pressure lines 3 are connected with drain main lines 6 by emergency bypass valves 10. Moreover, a number of devices for control and provision of preset parameters of working liquid are provided, namely: level transmitter 11, pressure limit valves 12, delivery limit valve 13. hydraulic distributors 2 are flexibly kinematically intercoupled by means of end hinge joints of rocker 14 coupled through middle hinge joint by means of tie-rod 15 with pitman arm. Hydraulic distributors 2 are provided with reactive chambers 16. EFFECT: reduced load on drive parts, increased service life of parts, provision of force to be applied to steering wheel proportional to force required for turning of vehicle wheels which increased information content. 1 dwg |
