Horizontal controller is for support frames of cross country vehicles has retaining plate fitted on support frame and upon plate is suspended pendulum switch to which is attached curved yoke

摘要

A retaining plate(19) is fitted on the support frame(4) of the vehicle, and upon the plate is suspended a pendulum switch(14) by means of a cross joint(15). A curved yoke(16) is attached to the pendulum switch. If the support frame rises or lowers at right angles to the direction of travel the pendulum switch by its two current sensors(17,18), following gravity force, try to maintain a vertically hanging position and come into contact with the current-conducting yoke. One of the sensors then sends a control signal to the hydraulic cylinder(3) to re-adjust the frame into a horizontal position.
