Abstract: A superimposed steering gear (3) for tracklaying vehicles superimposes the steering power required to steer the vehicle in curves on the vehicle drive system by means of summarizing differentials, and comprises a summarized hydrostatic-mechanical power branch in a summarizing gear (31). In order to minimize power losses due to inefficiency of the hydrostatic branch and to permit continuous steering in all radial regions, the summarizing gear (31) can be changed in at least two steps corresponding to two radial regions. The rotational speed of the components of the gear is adapted to each gear change point, thereby ensuring continuous transition.
