Arrangement for the diagnosis of the dimensions of a motor vehicle chassis

摘要

The invention relates to apparatus for the diagnosis of the dimensioins of a motor vehicle body positioned on an alignment bench comprising a frame constructed of sections on which are arranged terminal alignment-angle sets. These sets are comprised of mechanical parts including end or head pieces which are disposed on columns longitudinally displaceable and fixable in guide supports fastened appropriately on the frame to function as multi-Z-receptors. The configuration of the end or head pieces are fabricated such that upon positioning on the column they will have already in them the desired or predetermined XYZ-values or dimensional coordinates of the points of the motor vehicle to be checked when in either a complete or partially disassembled state. The arrangement is characterized in that at each end or head piece of the terminal receptors (3) electrical contacts (4) or electronic sensors are provided which when the portion of the motor vehicle being checked is in place on the bench a Yes/No signal is triggered depending on whether or not the individual point of the motor vehicle to be checked corresponds to the correct XYZ-value or dimensional coordinate and the result is evaluated or displayed by an evaluation and/or display arrangement (6).
