Description

Automobile tire anti-skid device

technical field

The utility model relates to the field of automobile anti-skid, in particular to an anti-skid device for automobile tires.

Background technique

In winter, especially in the ice and snow climate in the north, the road is covered with snow and the ground is wet and slippery. Many cars are equipped with anti-skid devices to avoid accidents. There are multiple tire anti-skid devices on the market, the most common of which are anti-skid chains. Its working principle is to concentrate the gravity of the vehicle on several points of the anti-skid chain, generate huge pressure, and roll through the ice and snow layer to reach the road surface, thereby increasing the frictional force to play an anti-skid effect and increasing the safety performance of the vehicle. Anti-skid chains are generally made of iron chains, tendon chains or rubber chains. Although the iron chain is relatively strong and durable, it is noisy, difficult to disassemble, and relatively heavy. During the anti-skid process, the mutual movement between the iron chain, the ground and the car tires causes serious wear and tear on the tires. As for tendon chains and rubber chains, although the several steel nails on the tendon or rubber are relatively light, they are also troublesome to disassemble and not durable enough, and are easy to break when encountering hard objects. These anti-skid chains have a common disadvantage, that is, it is not easy to load and unload and maintain. When the car is running, the anti-skid chain wraps the car tires, which will wear the car tires to varying degrees, and the friction between the car and the ground increased by using anti-skid chains is relatively small. The safety of automobile driving is not high.

Based on this, how to realize the easy loading and unloading of the automobile anti-skid device, convenient maintenance, and improve the safety of automobile driving without affecting the service life of automobile tires has become a technical problem urgently to be solved by those skilled in the art.

anti-skid hub 10 and center fixture 20,

Wherein, the anti-skid hub 10 is connected with a central fastener 20, and the anti-skid hub 10 and the central fastener 20 are fixed on the hub of an automobile tire.

Specifically, the anti-skid hub 10 is composed of an anti-skid hub body 101 and a plurality of anti-skid claws 102 . Wherein, the size of the anti-skid hub body 101 matches the size of the automobile tire, basically, the diameter of the anti-skid hub body 101 is the same as that of the automobile tire. There are a plurality of anti-skid grooves 103 on the outside of the anti-skid hub body 101, and the anti-skid grooves 103 are evenly distributed. Moreover, the anti-skid groove 103 is provided with bolt holes (not shown in the figure), and the anti-skid claw 102 is fixed in the anti-skid groove 103 by bolts.

Please continue to refer to FIG. 2 , which is a front view of a central fixture of an automobile tire anti-skid device according to an embodiment of the present invention. As shown in FIG. 2 , the central fastener 20 is provided with bolt holes 201 , and the positions of the bolt holes 201 are in one-to-one correspondence with the positions of the bolt holes of the hub of the automobile tire. When using the anti-skid device 1 for automobile tires, it is necessary to fix the anti-skid device 1 for automobile tires with the tires of the automobile. Specifically, first attach the anti-skid hub 10 to the hub of the automobile tires, and then connect the bolt holes 201 of the central fastener 20 to the tires of the automobile tires. The bolt holes of the wheel hub are corresponding, and then the central fastener 20 and the anti-skid wheel hub 10 are fixed together on the wheel hub of the automobile tire by bolts.

In order to ensure the tight connection between the center piece 20 and the anti-skid hub 10, a disc piece 104 is set between the center piece 20 and the anti-skid hub 10, and the small bolt hole on the piece piece 104 is the same as the small bolt hole 202 of the center piece 20. One-to-one correspondence, the disc fastener 104 is fixed on the central fastener 20 by bolts. The disk fastener 104 is closely connected with the anti-skid hub body 101 , and is fixed on the central fastener 20 through the disk fastener 104 .

Please continue to refer to FIG. 3 , which is a front view of an anti-skid claw of an automobile tire anti-skid device according to an embodiment of the present invention.
