ABSTRACT OF THE DISCLOSURE The disclosure describes a Caterpillar?type gear for vehicles with self-contained drive, in particular for hydro baggers, which comprises a driving drum, a roller wheel for guiding the endless chain, and chain links connected with each other by means of pins. In the longitudinal central plane of the driving drum, cam-type teeth are arranged which are provided with straight surfaces on the sides turned to each other. The external periphery of driving drum is provided, on both sides of the teeth, with rims for chain links. The cam-type teeth are arranged on the periphery of rim provided on both its sides with inclined planes for guiding the chain links. Chain drive plates of chain links, which are constructed as a two-web plate, are made in one piece with two-sided cams arranged centrally in chain link. The working surfaces of two- sided cams, which are turned toward cam-like teeth, are con- structed in such a manner that they serve as contact surfaces for cam-type teeth during the engagement. *Registered Trademark
