Abstract
In a tire chain comprising a running network (3) with steel links between chain strand portions of the running network and the tread of the tire supporting members (4) provided with guide hollows (5) are disposed. By varying the state of at least one lateral retaining strand (1 or 2) of the running network (3) it is possible for the purpose of varying the operating behavior of the tire chain to vary the position of the supported chain strands transversely to the guide hollows (5) in a way that enables the chain strands to project more or less over the outer surfaces of the supporting members (4).
Claims12
A tyre chain, more particularly a skid protection chain, comprising a running network with steel links which is held by lateral retaining strands of which at least one is adapted to be tensioned, and comprising non-metallic supporting members which are disposed between chain strand portions of the running network and the tread of the tyre and which have supporting surfaces, provided with guide hollows, for the running network parts supported on the supporting members, characterized in that:
- at the ends of the guide hollows (5,13,16,18) the supporting members (4,9,10,12,15,17) are provided with apertures (6) forming passages for running network portions,
- means for adjusting the tension of said at least one lateral retaining strand (1,2) for varying the extent to which the steel links of the supported running network parts project out of the guide hollows in said supporting members,
- at least parts of said guide hollows being orientated in a slanting direction relative to said lateral retaining strands due to the ground plan of said supporting members for preventing tilting movements of said supporting members.
