Patent ID: 6866276

Claim:
A vehicle suspension system comprising: a frame; a pair of laterally spaced apart suspension members pivotally supported on said frame and movable in a vertical direction; a pair of wheel ends with each wheel end supported on one of said suspension members; a stabilizer bar supported on said frame laterally between said suspension members, said stabilizer bar including opposing ends each respectively proximate to one of said suspension members; and a pair of resilient stabilizer bar links each respectively interconnecting one of said opposing stabilizer bar ends and one of said suspension members and transmitting a torsional force to said stabilizer bar in response to movement of said suspension members in said vertical direction during a roll condition, said pair of resilient stabilizer bar links having a first deflection rate and a second deflection rate during said roll condition with said first deflection rate being less than said second deflection rate, and said pair of resilient bar links transitioning from said first deflection rate to said second deflection rate and from said second deflection rate to an effective zero deflection rate.
