This system consists of the following elements (Figure 1): a shaft 1 ending in a toothed wheel which engages with the rack bar of the front steering, in such a manner that when the latter moves the shaft 1 is rotated. To this shaft is fixed the cam 2 which will have the profile considered appropriate (Figures 2 and 3). In contact with the cam 2 are the fingers 3a and 3b which are fixed to the coupling bar of the rear steering. The system functions as follows: when the shaft 1 is rotated (when the front steering moves), and as a result of this also the cam 2 as it is fixed to said shaft, the fingers 3a and 3b which are in contact with the cam 2 and are in turn fixed to the coupling bar, moving in turn the rear steering and rotating said wheels. <IMAGE>
