Abstract:
1. A bifurcated spring suspension system, comprising: a non-movable base; a movable base disposed opposite the non-movable base; a plate spring member comprising a first end and a second end, wherein the first end is disposed about the non-movable base and the second end is disposed about the movable base; a first cam disposed about a bottom surface of the plate spring member and disposed about the non-movable base and a second cam disposed about a top surface of the plate spring member and disposed about the movable base, wherein said first and second cams comprise a cam contact surface tapering from tangent to the plate spring progressively away from the plate spring while said plate spring is in an unbiased position; and a sensor in communication with a control module, said sensor adapted to measure the strain induced on the plate spring member and communicate said measured strain to a control module, wherein said control module is adapted to adjust the horizontal position of at least one of the first and second cams to vary the strain measured on the plate spring member.
