Abstract
The invention broadly includes a suspension system for a vehicle that includes a vehicle frame, at least one pair of shock absorbers attached to the frame and having piston stems extending from the shock absorbers and attached to extension arms pivotally attached to the frame. The extension arms are attached to the tire axles optionally attached to support arms. The support arms are also attached to the pivot connection. The pivot connection is between the axle and the shock absorber.
Claims18
A shock absorbing suspension system for a vehicle comprising:
- a vehicle frame having a front end, a rear end, and opposing sides;
- at least one pair of gas shock absorbers, each one of said pair of gas shock absorbers having a piston and a piston stem extending from said piston and through said gas shock absorber wherein each of said pair of gas shock absorbers is functionally attached to said frame;
- at least one axle, wherein at least one tire is rotatably attached to each of said at least one axle;
- at least two extension arms, each one of said at least two extension arms pivotally attached to said frame forming a pivotal connection and having a first end and a second end, wherein said each of said extension arm first ends is attached to said piston stem of one of said at least one pair of gas shock absorbers, said second extension arm end is attached to one of said at least one axle, wherein said pivotal connection is between said first extension arm end and said second extension arm end;
- a steering column attached to said frame;
- a pair of upper forks, each upper fork of said pair of upper forks having a first end and a second end wherein each of said upper fork first ends is attached to said steering column and each of said upper fork second ends is attached to said pivotal connection;
- wherein one gas shock absorber of one pair of said at least one pair of gas shock absorbers is attached to one of said pair of upper forks;
- and,
- wherein said pair of upper forks and said steering column form a functional attachment of each said one gas shock absorber of said one pair of said at least one pair of gas shock absorbers to said frame.

A motorcycle comprising a shock absorbing system, said shock absorbing system comprising:
- a frame for a motorcycle having a front end, a rear end, and opposing sides;
- at least one pair of gas shock absorbers, each one of said at least one pair of gas shock absorbers attached to said frame and having a piston and piston stem extending from said piston through said shock absorber;
- a pair of axles;
- at least two pair of extension arms each of said extension arms pivotally attached to said frame forming a pivotal connection and having a first end and a second end, wherein each of said extension arm first ends is attached to said piston stem of one of said gas shock absorbers, each of said extension second arm ends is attached to one of said pair of axles, and said pivotal connection of each of said extension arms is between said extension arm first end and said extension arm second end;
- and,
- a pair of gas lines connecting said pair of gas shock absorbers, wherein a first gas line of said pair of gas lines connects one pair of said at least one pair of gas shock absorbers above said piston and a second gas line of said pair of gas lines connects said one pair of said at least one pair of gas shock absorbers below said piston.
