ABSTRACT:
A caterpillar-type travelling mechanism for vehicles provided with a self-propelled drive, particularly hydraulic dredges, with a drive sprocket wheel, a guide wheel for the guidance of the caterpillar chain and chain links connected with one another by bolts. Cam-shaped teeth are arranged on the drive sprocket wheel in its longitudinal center plane, the teeth being provided on the sides which point toward one another with planar surfaces. The drive sprocket wheel is provided on its outer periphery with two running rims for the chain links, the rims being arranged on both sides of the teeth. The cam-like teeth are arranged on the periphery of a wheel flange, the latter on both sides being provided with inclined surfaces for guiding the chain links. The travelling mechanism plates of the chain links, which plates are formed as double-stud plates, are made of one piece with a two-sided cam arranged centrally in the chain link. The engagement surfaces of the two-sided cam, which engagement surfaces face the cam-like teeth, during the engagement are formed as contact surfaces for the cam-shaped teeth.
