Claim Text:
1. A force compensation system comprising: at least one elastomeric or laminated rubber bearing having two opposed loading members, a positive spring rate and a center or neutral position; and negative spring means having a negative spring rate and a center or neutral position, comprising: at least one elongated member or pusher having two opposed ends, and a source of force imposing compressive force between said ends of each of said elongated members, and two receiving and supporting members that moveably support and respectively each receive force applied by one of said two ends and are constrained in lateral motion relative to each other, whereby a component of said compressive force will be developed upon said receiving and supporting members in a direction of said constrained lateral motion; and said two receiving and supporting members of said negative spring means are respectively mechanically coupled together with said two opposed loading members of said at least one elastomeric bearing such that any said relative lateral movement imparted to said receiving and supporting members of said negative spring means is experienced substantially proportionately as movement between said two opposed loading members of said at least one elastomeric bearing, whereby any change in net torque developed upon said elastomeric bearings accountable to their said positive spring rate is at least partially compensated by the change ii net torque developed by said negative spring rate of said negative spring means.
