ABSTRACT:
According to the invention, in order to control the vehicle geometry of a chain or belt driven vehicle, chain alignment of the secondary drive is determined by means of a laser module (1) which is placed on the lateral surface of the chain wheel or the belt pulley and whose the laser beam is directed to the edge area of the chain or belt. Wheel alignment can also be determined, by arranging two pairs of circular segment shaped calibres (11), which are pressed flat against each other by pressing means (12) on each side of the rim of at least one back wheel and on at least one front wheel of the vehicle, and by emitting parallel laser beams (17) on both sides of one of the calibre pairs to the other calibre pair (17), the laser beams impacting measuring devices (13) which are arranged on both sides of the other pair of calibres. The dimensional accuracy of the swing and the front wheel fork can also be determined in a similar manner.
