the control system of the rotation of the box in a vehicle rail with variable structure

摘要

control system of the rotating box (1) in a railway vehicle (f) to variable structure, in which two pairs of actuators linear fluid under pressure (10a.10b) relating essentially vertically between the fund (1), and the opposite sides of the two trolleys (2, 3).the control system includes a single valve unit (13) common to the two pairs of actuators (10a, 10b).and the actuators of the two pairs disposed in correspondence to one side and the other side of the box, respectively (1) are connected between themselves and with the valve unit (13) via respectivefluid lines (17a, 17b) are common.
