Abstract
Abstract A vehicle including a pair of fluid-operated rams disposed adjacent opposite sides thereof, with each ram interposed, and accommodating relative movement, between the vehicle''s frame and an axle beneath the frame. Interconnecting the rams is a conduit system including a valve which is adjustable from within the vehicle''s cab to control fluid flow to and from the rams. In one position, the valve produces fluid interchange between the rams whereby a change in the effective length of one causes a related change in the effective length of the other. In another position, the valve frees the rams for independent operation.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
229 words
In a vehicle including a frame, a suspension system supporting the frame comprising transversely extending wheelsupported axle means, and a pair of elongated fluid-operated extensible devices disposed adjacent opposite sides of said frame, each device including one port into which fluid flows on extension of the device and another port into which fluid flows on contraction of the device, and being operatively interposed between the frame and the axle means therebeneath and adapted to accommodate relative movement between the frame and the axle means with a change in the effective length of the device, the improvement comprising conduit means operatively interconnecting the devices effective to control fluid flow to and from each device, devices and said conduit means constituting a fluid-filled closed circuit, said conduit means including a valve adjustable between first and second positions, said valve in its first position connecting the one port in each device with the other port in the other device and preventing fluid flow between the one port in each device and the other port in the same device, whereby a change in the effective length of one device causes a similar change in the effective length of the other device, and said valve in its second position connecting the one and the other ports in each device, freeing the devices from each other whereby changes in their respective effective lengths are unrelated.
Claim 2
Dependent Claim
229 words
In a vehicle including a frame, a suspension system supporting the frame comprising transversely extending wheelsupported axle means, and a pair of elongated fluid-operated extensible devices disposed adjacent opposite sides of said frame, each device including one port into which fluid flows on extension of the device and another port into which fluid flows on contraction of the device, and being operatively interposed between the frame and the axle means therebeneath and adapted to accommodate relative movement between the frame and the axle means with a change in the effective length of the device, the improvement comprising conduit means operatively interconnecting the devices effective to control fluid flow to and from each device, devices and said conduit means constituting a fluid-filled closed circuit, said conduit means including a valve adjustable between first and second positions, said valve in its first position connecting the one port in each device with the other port in the other device and preventing fluid flow between the one port in each device and the other port in the same device, whereby a change in the effective length of one device causes a similar change in the effective length of the other device, and said valve in its second position connecting the one and the other ports in each device, freeing the devices from each other whereby changes in their respective effective lengths are unrelated.
Claim 3
Dependent Claim
92 words
The vehicle of claim 1, wherein each of said devices comprises a cylinder, an elongated rod of substantially constant cross section extending longitudinally through the cylinder and mounted for reciprocation longitudinally thereof, a piston secured to said rod intermediate its ends for reciprocation therewith and forming a pair of fluid-holding chambers in the cylinder with one chamber on one side of the piston and the other chamber on the opposite side of the piston, and said one port opens into said one chamber and said other port opens into said other chamber.
Claim 4
Dependent Claim
23 words
The vehicle of claim 1 which further includes an operator''s cab and valve adjusting means accessible within the cab for adjusting said valve.
Claim 5
Dependent Claim
39 words
The vehicle of claim 3, wherein said valve is positioned adjacent said extensible devices and includes a shiftably valve spool moved in adjusting the valve, and said valve-adjusting means is connected by an elongated cable to said valve spool.
Claim 6
Dependent Claim
60 words
The vehicle of claim 1, wherein each extensible device is mounted between the frame and the axle means in such a manner that on extension of the device counterforces are produced along an inclined line, with the inclined lines along which such forces are produced for the two devices sloping toward each other progressing toward the midregion of the vehicle.
