Abstract:
1. A load-centering perch assembly engaging an end coil of a coil spring, comprising: a base member engaged with the end coil of a coil spring having a natural centerline, wherein said base member is tiltable with said end coil relative to a natural centerline of the spring during spring compression; a body member for receiving a load having a substantially fixed load direction, wherein said body member is in substantially fixed alignment with the load; wherein said body member and said base member are pivotally engaged; wherein during spring compression said base member tilts with the spring end coil relative to said spring natural centerline and pivots with respect to said body member to redistribute the applied load across the spring end coil; wherein body member and said base member define a cavity therebetween, wherein said cavity is filled with a substantially incompressible hydraulic fluid; and, wherein said cavity is sealed with at least one O-ring seal and wherein said hydraulic fluid and said at least one O-ring seal cooperate to cause said base member and said body member to float with respect to said body member and said base member such that said base member is spaced apart from said body member.
