Description

Tire anti-slip device {NONSKID APPARATUS FOR TIRE}

The present invention relates to a tire anti-slip device that is mounted on a tire to prevent the tire from slipping when driving on snowy roads or ice roads. It relates to a tire skid prevention device.

The tire anti-skid device is a winter safety device for a vehicle mounted on a tire to prevent the tire from slipping when driving on a snowy road or an icy road, and a plurality of chains which are arranged along the tire ground plane and closely adhere to the ground plane The most commonly used snow chain is a two-row wire that connects the ends of the chain on both sides of the tire and fixes them closely to the ground plane.

The tire anti-skid device must be able to increase the friction coefficient of the ground plane significantly and to withstand the load on the car. In addition, since it is used only intermittently on snow roads or ice roads, it should be easily removable. Therefore, conventionally, snow chains in which both the chain and the wire are made of metal are mainly used to satisfy the above-described requirements.

However, metal snow chains have no elasticity at all and protrude locally from the tire ground surface and are not elastically tightly adhered to the ground surface, causing severe body vibration and noise during driving, which greatly reduces ride comfort and local compression. As a result, there was a problem of damaging the tires and the road surface.

Accordingly, in recent years, tire slippers having a friction member made of a flexible material such as synthetic resin or rubber having a flat and constant width instead of a chain have been widely used.

1 is a perspective view showing a tire anti-skid device according to the prior art.

Conventional tire anti-skid device, as shown in FIG. 1, the friction with the plurality of friction members (3) arranged in close contact with the ground plane 2 of the tire 1 and arranged along the ground plane (2) Each end of the members 3 comprises two rows of wires 4 and 5 which are fixed at regular intervals and have shorter lengths than the circumference of the tire with the connecting means 6 fitted at both ends thereof. To the tire 1.

First, the friction members 3 are laid in the longitudinal direction on the ground just in front of the tire 1 so that the tires 1 are arranged in a forward direction, and then the vehicle is moved so that the tire 1 is placed on the friction members 3. Let it go up Subsequently, when the two wires 4 and 5, which are positioned inside and outside the tire 1, are connected at both ends thereof to form circular closed curves, the friction members 3 are connected to the tire 1 by the wires 4 and 5, respectively. Is pulled toward the center of the tire 1 to be in close contact with and fixed to the ground plane 2 of the tire 1.

When driving in this state, the friction members 3 come in contact with the road surface in advance of the ground plane 2, thereby preventing the tire 1 from slipping.

This conventional tire anti-skid device is made of a metal which has a small amount of vibration and noise of the vehicle body due to the driving, since the flexible friction members 3 having an area corresponding to the width are fixed in close contact with the ground plane 2 of the tire 1. Compared to snow chains, the riding comfort is not significantly reduced.

However, this tire anti-skid device is loosely fixed to the ground plane 2 in a loose state depending on the tension force due to the hoop stress of the wires 4 and 5, which are not elastic and the friction member 3 should have a tightening margin. Since the friction member 3 moves in the circumferential direction of the tire 1 when the friction member 3 is rubbed on the ground, the anti-slip effect is lowered and the friction noise is caused.

In addition, since the length of the wires 4 and 5 and the friction member 3 cannot be adjusted, the tires 1 can be mounted except the tire 1 of a predetermined standard.

Thus, the present invention can solve the problems of the conventional tire slip prevention device as described above, can be quickly removed and attached to the tire, as well as can be mounted on a tire of various sizes without limitations The object is to provide a tire slip prevention device.

The present invention is devised to solve the problems caused by the conventional tire anti-slip device as described above, the tire can be quickly removed and attached to the tire, as well as tires that can be mounted on tires of various sizes without limitations The purpose is to provide an anti-slip device.
