摘要

The running wheel (1) has a tire-rim (2) with central hub (3) connected by a disc-shaped metal main wheel part (4) to the rim. A gripper ring to one side of the runner wheel is integrated in the main wheel body formed from a round blank by a deep-drawing method. The free end of the laterally upward bent peripheral edge (9) of the blank is rolled over towards the wheel body and forms the gripper ring (8).
