Abstract
In a vehicle having a transverse axle and a body, and a shock absorber mounted between the axle and the body to absorb shock from vertical movement of the axle and prevent shock from being transmitted completely to the body of the vehicle, the improvement disclosed involves an apparatus for sensing tilt of the vehicle in combination with apparatus in the hydraulic system of the shock absorber which will prevent further tilt of the vehicle beyond a predetermined point sensed by the sensing unit.
Claims3
In a shock-absorbing system for a vehicle having a transverse axle and a body that comprises, on at least one side of the vehicle, a chamber partially or fully filled with hydraulic fluid and a movable piston at one end of said chamber attached to said transverse axle;
- the other end of the chamber being attached to said body of the vehicle;
- a plate within said chamber having at least one opening separating the fluid within the chamber into two portions;
- and means for dampening the movement of the piston when the piston is compressed or extended;
- the improvement which comprises a movable sealing means within said chamber which, when activated, seals said at least one opening in said plate;
- means for moving the sealing means to seal said opening in said plate;
- means for sensing the tilting movement of said vehicle, combined with said means for moving the sealing means to seal said opening when the sensing means is activated at a set tilt position of the body to prevent flow of said fluid from one portion of the chamber into the other portion of the chamber and thus prevent movement of the piston and further tilting of the body of the vehicle.
