A chain for mounting on a vehicle tire, in particular a sliding block chain, having a chain mesh, which is disposed at least on the tread of a vehicle tire in the mounted state of the chain and has a number of chain strands, each of which is formed by a number of chain links each with essentially straight longitudinal legs which run parallel to one another and are connected to one another at their ends by connecting elements in particular connecting rings. In the mounted state of the chain, the chain links of the chain strands lie on the tread at alternately positive and negative angles with respect to the tread. Wear elements are provided, realized as wear webs, which are fixedly connected to chain links of the chain mesh and which extend parallel to the longitudinal legs of the chain links.
The chain according to claim 1, wherein the wear webs comprises a profiled wear surface.
The chain according to claim 1, wherein the wear web extends essentially perpendicular to the tread.
The chain according to claim 1, wherein the wear web comprises a first length, the longitudinal legs of the chain links comprise a second length and the first and second lengths are substantially equal.
The chain according to claim 1, wherein the wear web comprises a first width and the longitudinal legs of the chain links comprise a second width, wherein the first width is equal to or greater than the second width.
The chain according to claim 1, wherein the wear web is constructed of a material that has greater wear resistance than the material of the chain links.
The chain according to claim 1, wherein the wear web is welded to the chain link.
The chain according to claim 1, wherein each chain strand of the plurality of chain strands comprises is an even number of chain links.
The chain according to claim 1, wherein the connecting element comprises a connecting ring, wherein the connecting ring comprises a major plane, wherein, in the mounted state of the chain, the major plane is essentially parallel to the tread.
The chain according to claim 1, wherein at least the first and second chain end links comprise an inside opening and a main plane, wherein the inside opening is configured to intersect the connecting ring, at an acute angle to the main plane of the respective chain link, wherein the angle has a value of 45 degrees±15 degrees.
The chain according to claim 1, wherein the connecting element comprises a connecting ring, wherein the connecting ring comprises a main plane, wherein, in the mounted state of the chain, the main plane of the connecting ring is essentially parallel to the tread, wherein at least one connecting ring, of the ring strand is cropped in comparison with the main plane of the ring, and the extent of the cropping can be predetermined.
The chain according to claim 1, wherein the connecting elements comprises a connecting ring, wherein the connecting ring has an oval shape.
The chain according to claim 1, further comprising a shoulder chain section comprising a plurality of chain links, wherein at least a first chain link of the shoulder chain section is connected to a connecting ring and comprises a wear web.
The chain according to claim 1, wherein each connecting element of the plurality of connecting elements comprises a connecting ring.
