A crawler undercarriage mechanism includes a plurality of running rollers, and at least one drive sprocket wheel which is provided with chain teeth, and has a running tread and wheel flanges on both sides. An endless chain with individual chain links which are connected releasably to one another by bolts and a plurality of interengaging outer and inner link plates is driven by the sprocket wheel. Each chain link has two guide webs which have a bearing surface, which interacts with the running treads, and a guide surface, which interacts with respective ones of the wheel flanges. The web guides have a cam-like element which connects the two webs and meshes with the chain teeth of the drive sprocket wheel. The drive sprocket wheel has an involute toothing arrangement which meshes with a rectilinear flank of the cam-like element, and top side of the respective guide web has a concavely curved bearing surface, which interacts with the convexly curved running-tread surface of the drive sprocket wheel. The webs also have an inner guide surface interacting with the wheel flanges and an outer guide surface providing for lateral guidance of the running rollers.
