Abstract
Abstract This disclosure relates to novel spring and/or shock absorbing means for an automotive vehicle or like suspension system, the shock absorbing and/or spring means including a pair of magnetic means operable to normally maintain the vehicle frame and wheels in spaced relationship due to magnetic forces of repulsion, and means normally biasing the pair of magnetic means toward each other. The pair of magnetic means may be permanent magnets or electromagnets, and in the latter case the electrical system of the vehicle is the source of electromagnet energization which may be varied by a conventional slide wire or equivalent potential divider to vary the magnetic force. Means are also provided for guiding the movement of the pair of magnetic means toward and away from each other.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
131 words
In a vehicle suspension system which includes a vehicle frame, a wheel support, and shock absorbing means therebetween, the improvement comprising a pair of relatively telescopic tubes, magnetic means in each tube operable to normally maintain said vehicle frame and wheel support in spaced relationship due to magnetic forces of repulsion, a rod, said rod passes through apertures in said magnetic means, said vehicle frame and said wheel support, said rod having opposite ends projecting through and beyond the apertures of said vehicle frame and said wheel support means coupling said rod ends one to said wheel support and one to said vehicle frame, and biasing means between one of said coupling means and one of said vehicle frame and wheel support for normally biasing said magnetic means toward each other.
Claim 2
Dependent Claim
131 words
In a vehicle suspension system which includes a vehicle frame, a wheel support, and shock absorbing means therebetween, the improvement comprising a pair of relatively telescopic tubes, magnetic means in each tube operable to normally maintain said vehicle frame and wheel support in spaced relationship due to magnetic forces of repulsion, a rod, said rod passes through apertures in said magnetic means, said vehicle frame and said wheel support, said rod having opposite ends projecting through and beyond the apertures of said vehicle frame and said wheel support means coupling said rod ends one to said wheel support and one to said vehicle frame, and biasing means between one of said coupling means and one of said vehicle frame and wheel support for normally biasing said magnetic means toward each other.
Claim 3
Dependent Claim
20 words
The improvement in a vehicle suspension system as defined in claim 1 wherein said tubes are constructed from anti-magnetic material.
Claim 4
Dependent Claim
20 words
The improvement in a vehicle suspension system as defined in claim 1 wherein said biasing means is a coil spring.
Claim 5
Dependent Claim
29 words
The improvement in a vehicle suspension system as defined in claim 1 wherein said biasing means is a coil spring in external telescopic relationship to said one rod end.
Claim 6
Dependent Claim
24 words
