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, the improvement disclosed involves apparatus for sensing tilt of the axle in combination with separate hydraulic system to prevent further tilt of the axle beyond a predetermined point sensed by the sensing unit.
Claims16
In a vehicle having an interior and an exterior, a transverse axle and a body, and being subject to swaying and tilting when the vehicle turns a corner or is driven around a curve, the improvement which comprises an apparatus for limiting the swaying and tilting movement of said vehicle comprising, on at least one side of the vehicle, a chamber partially filled with hydraulic fluid and having an upper end and a lower end;
- a movable piston sealing the lower end of said chamber, attached to said transverse axle;
- the upper end of the chamber being closed and attached to said body of the vehicle;
- a plate within said chamber having a substantially central opening separating said fluid within the chamber into a lower portion and an upper portion;
- movable sealing means within said chamber and when activated seals said central opening;
- means for moving the sealing means to seal said opening;
- means for sensing the tilting movement of said vehicle, electrically combined with means for moving the sealing means to seal said opening when the sensing means is activated at a predetermined tilt position of the body to prevent flow of said fluid from the lower portion of the chamber into the upper portion of the chamber and thus prevent tilting of the frame or body of the vehicle.
Apparatus for a vehicle having a transverse axle and a body comprising, on at least one side of the vehicle, a chamber partially 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;
- movable sealing means within said chamber when activated seals, said at least one opening;
- means for moving the sealing means to seal said opening;
- means for sensing the tilting movement of said vehicle, combined with 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 tilting of the body of the vehicle.
Apparatus for a vehicle having at least the following two structural elements, a transverse axle and a body comprising, on at least one side of the vehicle, means comprising a chamber having two portions partially filled with hydraulic fluid;
- a movable piston at one end of and within said chamber and attached to one of said structural elements;
- the other end of the chamber being attached to the other of said structural elements of the vehicle;
- means within said chamber to separate said fluid within the chamber into two portions;
- means for sensing the tilting of one of said structural elements toward said other structural element;
- sealing means within said chamber and, when activated by said means for sensing tilting, to prevent any flow of said fluid from one portion to the other portion of the chamber, and, thus, prevent tilting of one of said structural elements toward said other structural element.
