Anti-slipping device for car wheels

FIELD: motor-car construction industry.

SUBSTANCE: anti-slipping device for car tires consists of a chained shell with two lines (9) of chain links (11), jointed together at a regular interval by means of an intermediate element (15). Guiding links (23) are engaged with the intermediate elements (15). The guiding links (23) connect chained shell with retaining brackets (29) placed on car wheel in a star-like manner. The retaining brackets (20) and chained shell are connected by means of corresponding guiding link (23) of the chain.

The subject of the invention is the anti-skid device for vehicle according to the restrictive part of paragraph 1 of the claims. The anti-skid device for the wheels of the car are, on the one hand, in winter as snow chains and, on the other hand, can be equipped with chains tires special vehicles to protect, for example, when used in the quarries of tyre from premature damage to the sharp stones. This invention relates, in particular, to anti-skid devices for use in snow and/or ice. Consider the anti-skid device is a device that is held by the shoulders, a star located at the installed rotatably on the wheel rim of the vehicle support ring.

The anti-skid device of this type known. For example, in EP-B1 0911193 described the anti-skid device for a wheel of a motor vehicle comprising fastened to the wheel and rotate with respect to it in assembled condition, the retaining device. In this known device, which contains letiziabruni chain armor, which is adjacent to the working surface of the tire, shackles connected only with facing to the outside of the car wheel chain branch. For this purpose, on to ncah restraint brackets are rotatable and movable up and down on the limited amount of funds on the front edge which sociopathy the recess by means of bolts rigidly attached to the chain links lying outside branch circuits. In addition, distantsiruyutsa the part that connects both branches of the circuit, is held in the slot on the retaining brackets so that distantsiruyutsa item always runs parallel to the retaining bracket and thereby holds both branches of the chain in the direction of motion of the tire. This is a known anti-skid device has the disadvantage that, on the one hand, in the area lying outside branch on the retention bracket, attach the head, which covers both sides of the chain and therefore is compared to the branches of the circuit larger in the radial direction size, which negatively affects movement. In addition, this head with every hit on the roadway hits it and therefore subjected to strong wear. Fixed in the head of the chain links are held by separate bolts, which in turn should be fixed or locked. These elements when hitting the roads are also subject to heavy wear and thereby pose a threat to traffic safety.

The objective of the invention is the creation of the anti-skid device of this type which does not have the drawbacks of known devices and has a very simple on the cheap to manufacture and is less subject to wear design.

This problem is solved by using the anti-skid device with signs of paragraph 1 of the claims. Particularly preferred embodiments of the given in the dependent claims.

Unexpectedly, it was found that using svobodnoradikal connection between distantsiruyutsa part that connects both branches of the circuit, and the free end shackles without radial increase of the diameter of the anti-skid device to accurately position and guide the chain armor on the working surface of the tire.

Below is a detailed description of the invention on the basis of an exemplary embodiment with reference to the accompanying drawings, which depict:

figure 1 is adjacent to a bus, a vehicle anti-skid device, top view;

2 is a connection between the retaining bracket and chain armor in an enlarged view;

3 - cut the connection on the line III-III in figure 2.

Figure 1 in phantom lines schematically indicated bus 1 with its both lateral sides 3. To the working surface 5 of the tire 1 is adjacent device 7 anti-skid containing two passes on the relevant sections parallel to the branch 9 of the chain of interconnected links 11 of the circuit. Both branches of the circuit 9 is held at a distance from each other using distantsiruyutsa ale is now 13.

With uniform intervals, for example once every four distantsiruyutsa elements, both branches 9 of the chain are brought together in the intermediate element 15. The intermediate element 15 includes an elongated slot 17, the lateral ends of which are preferably made circular opening 19 and in the middle between holes 19 made extended section 21. In both holes 19 are held the last links of 11 chains of both branches of the circuit 9. In section 21 includes a guide link circuit 23, which, in addition, is located in the hole 25 at the free end 27 of the retaining bracket 29 (see, in particular, figure 2). The guide link 23 of the circuit is approximately perpendicular to the direction L of movement of the tire. The height h of the guide link in the chain that its one side adjacent to the working surface 5 of the tire 1, is essentially equal to the height h of the links 11 branches 9 of the chain, which also are in engagement with the intermediate element 15. For better clarity, figure 3 is not shown extending from the intermediate element 15 and connected with the intermediate element 15 links 11 of the chain.

Retaining bracket 29 is connected in a known manner with its opposite free end 27 end, not shown, mounted on the wheel rotatably support ring.

Between the retaining bracket 29 and educated of the two branches 9 of the chain and d is stanzioni elements 13 chain armour arises due to the guide link 23 chain swivel. Due to the fact that the intermediate element 15 connects together both branches 9 chain, chain armor, though the hinge is connected with the holding bracket, just goes. That is, both branches of the circuit 9 can be moved relative to each other in the direction L of the movement. Connection shackles 29 with both branches of the circuit 9 causes the side chain of the shell to secure the bracket 29 are only a small force. Additionally, due to the same height h guide link 23 of the chain, as well as links 11 of a chain armour above the working surface 5 of the tire is ensured that also in the connection between the retaining bracket 29 and chain armor is adherence of chain armour and guide link circuit 23 to the road pavement. Thus, the wear of all parts 11, 15 chain is always the same. Through the use of open guide link circuit 23, as shown in figure 3 by broken lines, can chain armor to free from restraint brackets 29 and flip when the respective wear.
