Abstract
Abstract An automobile including in combination, a chassis, wheels rotatably supporting the chassis, and spring assemblies connected between the chassis and wheels. The spring assembly of each wheel comprises a spring connected at one of its ends to a wheel and an hydraulic ram connected between the other end of the spring and the chassis. A fluid displacement cylinder communicates with the rams and is carried by the chassis. The piston of the fluid displacement cylinder is connected to an air foil which creates a negative lift to apply a downward force on the piston which functions to add a simulated weight to the chassis and compress the springs of the wheel assemblies and to displace fluid from the fluid displacement cylinder to urge fluid to the rams to raise the chassis with respect to the springs. Thus, as the force exerted by the wing adds to the weight of the vehicle and causes contraction of the wheel springs, the chassis is maintained a predetermined distance from the ground by the rams.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
157 words
An automotive vehicle including in combination a chassis, wheel assemblies rotatably supporting said chassis, and spring assemblies connected between said chassis and said wheel assemblies, each of said spring assemblies comprising a spring member connected at one of its ends to a wheel assembly and expandable and contractable in response to the vertical movement of its wheel assembly with respect to said chassis, a fluid displaceable ram member connected between the other end of said spring member and said chassis, fluid displacement means carried by said chassis and communicating with the ram member of the wheel assemblies whereby the fluid displacement means transmits fluid pressure to the ram members and the ram members expand to raise the chassis with respect to the spring members, and an air foil member connected to said fluid displacement means, said air foil being of a configuration to create a downward force on said chassis and to actuate said fluid displacement means.
Claim 2
Dependent Claim
157 words
An automotive vehicle including in combination a chassis, wheel assemblies rotatably supporting said chassis, and spring assemblies connected between said chassis and said wheel assemblies, each of said spring assemblies comprising a spring member connected at one of its ends to a wheel assembly and expandable and contractable in response to the vertical movement of its wheel assembly with respect to said chassis, a fluid displaceable ram member connected between the other end of said spring member and said chassis, fluid displacement means carried by said chassis and communicating with the ram member of the wheel assemblies whereby the fluid displacement means transmits fluid pressure to the ram members and the ram members expand to raise the chassis with respect to the spring members, and an air foil member connected to said fluid displacement means, said air foil being of a configuration to create a downward force on said chassis and to actuate said fluid displacement means.
Claim 3
Dependent Claim
120 words
In an automobile including a chassis, wheels, and laterally extending aiR foil attached to said chassis, said air foil being of a configuration to exert a downward force when moving with the automobile at a speed to create a wind flow across the surfaces of the air foil, the improvement therein comprising first expandable fluid displacement means connected to said air foil and chassis and responsive to the downward force exerted by the air foil to contract and displace a portion of its fluid, second expandable fluid displacement means communicating with said first fluid displacement means and positioned between the wheels and the chassis of the automobile and arranged to elevate the chassis with respect to the wheels when expanded.
Claim 4
Dependent Claim
120 words
In an automobile including a chassis, wheels, and laterally extending aiR foil attached to said chassis, said air foil being of a configuration to exert a downward force when moving with the automobile at a speed to create a wind flow across the surfaces of the air foil, the improvement therein comprising first expandable fluid displacement means connected to said air foil and chassis and responsive to the downward force exerted by the air foil to contract and displace a portion of its fluid, second expandable fluid displacement means communicating with said first fluid displacement means and positioned between the wheels and the chassis of the automobile and arranged to elevate the chassis with respect to the wheels when expanded.
Claim 5
Dependent Claim
32 words
The invention of claim 2 and further including springs connected between each wheel and said chassis, and wherein said second expandable fluid displacement means is positioned between said springs and said chassis.
Claim 6
Dependent Claim
31 words
The invention of claim 2 and further including means for varying the angle of attack of said air foil in response to the fluid displaced from said first fluid displacement means.
Claim 7
Dependent Claim
71 words
The invention of claim 2 wherein said second expandable fluid displacement means comprises an expandable ram in series with a spring member at each wheel of the automobile and wherein said first expandable fluid displacement means comprises a first expandable piston-cylinder means communicating with the expandable rams on one side of the automobile and a second expandable piston-cylinder means communicating with the expandable rams on the other side of the automobile.
