Vehicle suspension system for stable squat magnitude responses

Abstract

A wheel suspension system having under powered acceleration a stable squat magnitude response.

1 . A vehicle suspension system for a shaft driven wheel suspension, wherein said suspension system projects an instant force center which moves in an upward direction in relation to gravity as the vehicle suspension is compressed while standing on level ground. 
   
   
       2 . A vehicle suspension system for a shaft driven wheel suspension, wherein said suspension system projects an instant force center which moves in a direction horizontally closer to the driven wheel rotation axis as the vehicle suspension is compressed while standing on level ground. 
   
   
       3 - 6 . (canceled) 
   
   
       7 . A suspension system for a chain driven rear wheel suspension, with a driving cog, where said driving cog has a pitch diameter, wherein said suspension system projects an instant force center which moves in an upwards direction as the vehicle suspension is compressed and said instant force center follows an instant force center path, and said instant force center path describes an instant force center focus, and said instant force center focus lies within the area described by the driving cog pitch diameter at a point or points during the suspension compression.
