Abstract
The present invention is a method with a 3-dimensional measuring apparatus for determining vehicle suspension parameters, which include roll center, scrub radius, etc. The apparatus measures the upper and lower control arm pivot locations, which include coordinate planes X, Y, and Z, where X is longitudinal distance from front axle centerline, Y is height above ground, and Z is distance from vehicle centerline. Suspension measurements are provided by at least one lower support (), at least one vertical member (), at least one horizontal arm (), and at least one indicator support () located at a ground plane in proximity to a tire's tread. Indicator (BC') on indicator support () indicates at least one lower steering pivot location determined by horizontal arm (). Wheel pivot locator () connected to indicator support () locates kingpin trail (C″) and provides a way for measuring the scrub radius between kingpin trail (C″) and tire centerline (E).
