Claim:
1. A tracked chassis, comprising: a continuous track that comprises ground plates coupled so as to be rotatable relative to each other, wherein said continuous track is guided via a driven sprocket having at least one toothed ring for driving the continuous track, wherein each of said ground plates has at least one hump link with hump link flanks oriented in a running direction of the continuous track, wherein the hump links are configured to engage in recesses formed between radially protruding teeth arranged on a circumference of the sprocket while the continuous track circulates over the sprocket, wherein said ground plates are coupled to each other via at least one connecting sideplate, wherein said at least one connecting sideplate is arranged between the ground plates and is configured such that the ground plates are shiftable in parallel relative to one another, wherein the teeth and the hump links each have an angular shape with linearly extending teeth flanks and said hump link flanks, respectively, such that leading teeth flanks of the teeth engaged with the hump links flatly contact the hump link flanks in all states of wear while the continuous track circulates over the sprocket, wherein a running, surface-like support of the continuous track on the sprocket only occurs on the teeth flanks and the hump link flanks of respectively engaged teeth and hump links during circulating of the continuous track, wherein upon occurrence of a wear-related elongation of the at least one connecting sideplate and a corresponding increase in a path of the continuous track as a result of the at least one sideplate that is elongated allowing a parallel displacement of two adjacent ground plates, the hump link flanks of the hump links engaged with the sprocket slide radially outward on the teeth flanks of individual successive teeth from a last engaged hump link to the first hump link being engaged while maintaining surface contact, such that centers of respective, effective contact surfaces between the hump links and the teeth lie on a spiral-shaped path around the center of the sprocket.
