Abstract
A spring perch assembly for automatically centering a load applied to a spring is provided. The assembly includes a body portion and a base portion which when engaged may tilt relative to one another. When disposed between a spring and an applied load, the assembly automatically centers the load along the spring's natural centerline.
Claims20
A load-centering perch assembly engaging the 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 the 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;
- and,
- 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.

A load-centering perch assembly for engaging a coil spring comprising:
- a base member engaged and tiltable with an end coil of a coil spring relative to a natural centerline of the spring;
- a body member engaged with a fixed direction load and having a fixed load centerline;
- whereby said body member and said base member are pivotally engaged with a cavity separating said body member from said base member, such that said base member tilts with the end coil of the spring relative to the spring centerline and pivots relative to said body member during spring compression;
- and,
- wherein said cavity is filled with a substantially incompressible fluid.

A load-centering perch assembly for a coil spring in a vehicle suspension system, comprising:
- a base member engaging an end coil of a spring having a natural centerline;
- a body member having a fixed load direction attached to a vehicle suspension shock absorber;
- wherein said body member and said base member are pivotally engaged;
- and,
- wherein said base member is tiltable with the end coil of the spring relative to the natural centerline of the spring and pivots relative to the fixed load direction and said body member during spring compression.
