Apparatus and method for determining shim changes to adjust camber and caster of vehicle wheel

摘要

Apparatus for determining shim changes to adjust the camber and caster of a vehicle wheel includes a memory for storing preselected information relating to dimensions of a vehicle wheel control arm for at least two different vehicles, the information being different for the two vehicles. The memory also stores vehicle wheel alignment specifications for the vehicles. Vehicle wheel alignment instruments measure the camber and caster of vehicle wheels. A computer is operatively connected to the memory and is responsive to the measurements from the vehicle wheel alignment instruments for comparing the measured camber and caster to corresponding caster and camber specifications for the vehicle wheel to determine required changes in camber and caster. The computer uses the required changes and the preselected dimensional information to determine the changes required in shims to adjust the measured camber and caster to the specifications. An output device informs a user of the shim changes required to adjust the measured camber and caster to the specifications.
