Abstract:
A spring system and front wheel fork assembly for a two-wheel vehicle having a frame, the spring and front wheel fork assembly comprising:a bifurcated member for holding a front wheel of said two-wheel vehicle; said bifurcated member having first and second legs; first and second spring components mounted coaxially to each other on said first leg so as to face toward each other in the manner of mirror images; said first spring component including a first roll-off piston and a first rolling-lobe resilient member coacting with said first roll-off piston during operation of said spring system; and, said second spring component including a second roll-off piston and a second rolling-lobe resilient member coacting with said second roll-off piston during operation of said spring system; said first and second roll-off pistons being formed on said first leg and being rigidly connected to each other so as to define a first double roll-off piston; third and fourth spring components mounted coaxially to each other on said second leg so as to face toward each other in the manner of mirror images; said third spring component including a third roll-off piston and a third rolling-lobe resilient member coacting with said third roll-off piston during operation of said spring system; said fourth spring component including a fourth roll-off piston and a fourth rolling-lobe resilient member coacting with said fourth roll-off piston during operation of said spring system; said third and fourth roll-off pistons being formed on said second leg and being rigidly connected to each other so as to define a second double roll-off piston; a first outer jacket common to both of said first and second rolling-lobe resilient members; and, a second outer jacket common to both of said third and fourth rolling-lobe resilient members.
