Description

Anti-skid device of car wheels {PREVENTING DEVICE OF WHEEL SLIPPING FOR AUTOMOBILE}

The present invention relates to an anti-skid device of a wheel for a vehicle, and more particularly, to prevent slippage of a vehicle wheel that can be easily detached and detached from a tire of a vehicle when the road surface is slippery in winter. Relates to a device.

In general, when the snow is accumulated or frozen on the road surface when the vehicle is running in winter, the tire is not able to run only by driving the snow chain to the tire.

The snow chain is not used much because it is very difficult to fasten to the tire of the vehicle and it is very inconvenient to remove it from the tire again after the snow road.

In addition, the snow chains cause severe wear of the snow chains and roads when driving on non-snow asphalt, and do not play a role in the road covered with ice.

The anti-skid device that has improved this is fixed disk 51 which is fastened to the hub bolt (B) by the adapter 50 on the side of the wheel (W) of the tire (T), and the fixed disk ( 51, and the non-slip arm 52 is coupled to the support disk 54, which is fastened by the bolts 53, and the support disk 54 is coupled to the fixed disk 51 through the wedge-shaped locking device. It consists of a retaining ring (55) for fixing.

In addition, a spring latch (not shown) is provided so that the locking device is not released while the tire is running.

That is, in order to use the anti-slip device, the non-slip arm 52 of the support disk 54 described above is mounted in the state where the fixing disk 51 is mounted to the hub bolt B by the adapter 50. After opening the two to be in close contact with the tire (T), when the retaining ring 55 is inserted into the fixed disk 51 on the outer surface of the support disk 54 is rotated by a wedge-shaped locking device. .

When the retaining ring 55 is fixed by the locking device, the anti-slip arm 52 wraps about half of the tread portion of the tire T while the support disk 54 is fastened to the tire T. In this state, when the vehicle travels, the anti-skid arm 52 comes into contact with the snow road so that the vehicle can travel without slipping.

Of course, in order to remove the non-slip arm 52 and drive the normal road surface, the retaining ring 55 is rotated in reverse to separate from the fixed disk 51, and the support disk 54 is detached from the tire T. By being separated from), it is possible to easily remove the anti-skid devices such as snow chains.

However, in order to detach the support disk in the state where the fixed disk is fixed to the wheel of the tire as described above, it is necessary to tighten or loosen the retaining ring with a relatively large force. There is a problem that becomes relatively difficult.

In addition, since the anti-slip arm fixed to the support disk with bolts or rivets is a consumable to wear, it is often necessary to replace them, and there is a problem that it is very inconvenient to replace the anti-slip arm by loosening the bolts or rivets. .

In addition, since the length of the non-slip arm is not adjustable, there is a problem in that the non-slip device may not be compatible with the tire of the vehicle.

Therefore, the object of the present invention is to solve the above problems, the non-slip arm and the support disk is configured to be easily removable, as well as the sliding of the wheel for the automobile that can easily combine the support disk and the fixed disk with a small force It is to provide a prevention device.

The present invention also provides an anti-skid device for an automobile wheel, which is configured to be able to vary the length of the non-slip arm, so that the driver can use the anti-slip device even when the tire is replaced with a tire of one size.

In order to achieve the above object, the present invention provides a wheel fixing means formed with a nut so that the hub bolt of the tire wheel is inserted and pressed and fixed to the other side, and a plurality of fixings to be fixed by the wheel fixing means. A fixed plate formed with a ball, a disk in which a plurality of arm portions are arranged at a predetermined angle and a seating portion and a hole are formed in which a locking plate is seated in the center, and the disk is rotated by pressing the disk in the state interposed therebetween.
