This device is for installation of chains on the wheels of cars, and also for taking the chains off from the wheels while driving. This device is built of a two-way clutch consisting of an outside disk (11) and inside disk (12). They both work on undetachable disk (25) and on the two brake shoes (7), which are attached to the inside of the wheel and chains (2) going through slanting groove (3) in the tire1, from the ring (10) of clutch disk (11) to the ring (31) or smaller rings installed remanently to the rim (20). Putting on the chains (2) on the grooves (21) in tire, or taking them off is done by compressing clutch disks (11) and (12), and the back movement is caused by transmission consisting of a gear rack (15), (4) and (5). |
