The invention relates to the field of transport engineering and can be used in various fields of national economy in the design of tires trackless vehicles (cars, tractors, motorcycles and so on). Most of these tires are designed for cars. Especially advantageous to use the bus when operating vehicles on mountain roads and ice.

Known tire wheel trackless vehicles with removable anti-skid device containing at least one is made in the form koltseobrazno a bent rod and provided with anti-skid elements prugovecki ring located in an annular groove around the tire tread on its surface. The Hoop is made permanent, in the form of an endless koltseobrazno a bent rod, igna hoops and are located between the hoops above the tread surface (U.S. patent 4334586, class B 60 C 27/00, 1982).

This bus has significant drawbacks:

1. The production of such anti-skid device can be profitable only if will be set to their mass production, because it requires expensive special equipment and special manufacturing techniques.

2. Plastic, which is required for the manufacture of hoops, quite expensive and scarce.

3. With such devices, anti-skid invalid drive at high speed on paved roads, as items of snow are at a considerable distance above the surface of the tire tread, have quite a lot of weight and poor cushioning.

4. On this bus ride without hoops disadvantageous, as it would be a great danger of damage to the bus (for example, a hole in the tube) due to the large width and depth of the ring grooves.

5. It requires considerable time to ensure that the anti-skid device to put on the bus or off bus.

Also known tire wheel anti-skid containing at least one is designed as one monolithic bent koltseobrazno rod connected with each other Bunny washers with through holes, they put on the stud Hoop. Each end of the rod is bent in the form of a hook, and hooks are geared to each other (application N 5037830, priority 16.04.92).

This bus has significant drawbacks:

1. Difficult to put on the washer, when the ends of the rod are already bent in the form of hooks.

2. The hooks on the end of the rod spoil the appearance of the tire.

The aim of the invention is to facilitate mounting washers on the rod and the improvement of technical characteristics of the bus.

This objective is achieved in that the proposed bus the ends of the rod are connected using couplings, and these ends are aligned relative to each other in a through hole provided in the clutch.

As is known, the proposed bus has a removable anti-skid device containing at least one is designed as one monolithic bent koltseobrazno rod connected with each other ends, prugovecki ring located in an annular groove around the tire tread on poverhnosti with washers through holes, which they put on the rod, Hoop, but we offer bus appeared significant differences. The prototype of every con is redlagaemoe same bus of the ends of the rod are connected using couplings, moreover, these ends are aligned relative to each other in the through hole, predusmotrennoi in the clutch.

Such essential features no prototype, no other known tire.

Additional claims of the proposed bus listed and other significant differences. Here are some of these differences:

1. The clutch consists of two coupling halves with flanges, which are connected to each other by means of fixing elements.

2. The coupling mounted on the rod with thread.

3. Inside washer is adjustable along the length of the dowel in the form of a screw.

4. Each washer mounted on the rod without a gap between the wall stud and the wall of the bore of the washer.

5. On the surface of the tread are quick lugs, hooked rods hoops tires.

All of the above differences constructive features of the proposed bus from the constructive features of the prototype are very significant, due to which goal of the invention. We offer tires, there are properties that are not and cannot be that of the prototype. As a result, not only significantly improves acetelyne signs is unknown in General. Therefore, it can be argued that the proposed solution meets the criterion of "substantial differences".
