The present invention relates to an anti-slip device for an automobile, and in particular, it does not contain moisture, and thus it is easy to lighten weight and dry operation, and to prevent scattering of debris due to breakage caused by centrifugal force or friction vibration during driving. It is possible to prevent multiple accidents by preventing damage from being scattered while preventing damage. It relates to a non-slip device for automobiles.

In general, the non-slip device of the vehicle is a snow chain that is mounted on the tires of the car to prevent the skids when the road is frozen by snow, and the chain can be installed in areas with high accident rate due to road damage such as highways. Special types of tires, such as snow tires and spike tires, are also used to prevent slippage.

Such an anti-slip device for a vehicle uses a ladder-shaped chain by a cable or an integrated snow chain in the form of a block connected by a urethane. The integrated vehicle anti-skid device includes a connection ring or a connecting cable while driving. When disconnected, the fixing force of the anti-skid device for the entire vehicle is lost, and even if the entire anti-skid device for the vehicle is not lost or released from the tire, there is a problem that it is not economical.

In addition, the integrated vehicle anti-skid device is difficult to install and detach in the case of a female driver, the elderly and the disabled, can not be quickly mounted in the situation of encountering a sudden snow or ice road, and also because the vehicle is mounted moving back and forth In the steep slopes, the removal and replacement work was very difficult.

In addition, the integrated vehicle anti-skid device is adapted to be appropriately mounted on the tire of a general passenger car, and in the case of a large bus or a truck for transporting passengers or cargo, the rear wheel, which is the power transmission wheel, is a double wheel (the tire reduces the burden weight per vehicle). Since the use of a double wheel to reduce the risk of puncture), the integrated vehicle anti-skid device has a problem that it is difficult to install in large vehicles adopting a double wheel.

In addition, the integrated anti-skid device for the integrated vehicle is very troublesome to install and remove the chain, and considering that the width of the double-wheel tire of the transport vehicle is relatively narrow and the diameter thereof is small, the vehicle anti-skid device manufactured for passenger cars is a truck or a bus. There was a problem in that when the mounting on the tire, such as the fixed fixing force and the adhesion force is lowered to have an effective power transmission and stopping force.

In order to solve the above problems, an anti-slip device for a vehicle is proposed, in which a plurality of chains formed on a double wheel constituting a rear wheel of a large vehicle pass through a center of a tire (wheel) and coupled to a plurality of chains, but have the following problems. .

That is, in the conventional vehicle anti-skid device is a snow chain is mounted through the wheel that is the mounting surface of the tire on the outer periphery of the tire, the snow chain is rotated together with the rotation of the tire, the tire is rotated at high speed If the stopping force is continuously transmitted, the gap is not maintained, and a phenomenon occurs that is concentrated in one direction, thereby failing to transmit the overall and constant braking force to the double wheel, and the load is concentrated on the snow chain, thereby causing the chain to be damaged or separated.

In addition, the conventional vehicle anti-skid device has a problem that the load is concentrated when the vehicle is driven, so that the binding portions of the snow chain fixed to each of the plurality is separated and the braking force is suddenly canceled and the possibility of a large accident increases with the safety greatly reduced. .

In addition, the conventional vehicle anti-skid device has a structure for fastening a plurality of spikes directly to the abdominal ring in the absence of a means for maintaining the interval, so that the snow chains are mounted to one side while being biased to one side when traveling on uneven terrain. The entangled braking force acts in the direction of the centrifugal force due to the sharp cornering, such that the steering is steered in a direction different from the steering direction manipulated by the driver, causing an accident.

In order to solve the problems of the conventional vehicle anti-skid device has been proposed in the Republic of Korea Utility Model Registration No. 20-424423.

A typical example of such a conventional vehicle antiskid device is shown in FIGS. 1A and 1B.

Conventional vehicle anti-skid device (1) is flat on both sides of the insertion end (2a) and the insertion end (2a) is bent in the V-shape so that the middle portion is bent into the inter-space of the abdominal ring and each tire surface of the abdominal ring. A plurality of spikes 2 composed of a close end 2b having a projection 2b 'formed in an integral shape;

A chain 3 connecting the insertion ends 2a of the plurality of spikes 2;

Length adjustment on the opposite side of the fastening hole (4b) fastened to the engaging projection (2c) of the spike (2) coupled to the other end side of the chain (3) to the rear of the ring (4a) formed to be connected to one end of the chain (3) Connecting rods 4 formed with a plurality of length adjusting mechanism (4c) for;

A hook 5c integrally formed at one end of the pair of elongated first and second support plates 5a and 5b and hooked to the chain 3 and between the other ends of the first and second support plates 5a and 5b. A long tightening end 5d arranged in the space and fastened to a hinge 5d ', and one end thereof is fastened to the inner end of the tightening end 5d by a hinge 5e', and the other end is caught. It comprises a binding sphere 5 composed of a tension holding end (5e) formed integrally bent ring.

As described above, the conventional vehicle anti-skid device (1) is inserted into the space between the two-wheel tire constituting the rear wheel, such as a large truck 'V'-shaped insertion end (2a) and spikes along the outer peripheral surface of the double wheel (2) ) And by pulling the chain (3) to further enhance the adhesion to the abdominal ring.

Subsequently, the chain 3 is tightened to the engaging projection 2c of the spike 2, which is located at the end of the fastening hole 4b of the connecting table 4, which is coupled to one end of the chain 3 using the ring 4a. And pull together.

Then, the tension retaining end 4f of the binding port 4 is fastened to the length adjusting port 4b of the connecting table 4, the hook 4c is coupled to the chain 3, and then the tightening end 5d is flipped over. (4) and the binding port (4) is to be combined to maintain the pulled state.

In this way, the vehicle anti-skid device (1) fastened to the double ring is supported by the projection (2b ') of the slippery surface due to the ice or snow accumulated along the rotation of the double wheel as the vehicle moves, and quiet due to the thin thickness of the spike (2) And it can run without slipping in a state where less vibration is generated.

However, the conventional non-slip device for a vehicle has a problem in that the close end is easily damaged by a torsional phenomenon in which spikes are pushed by the rotational force of the double wheel because the vehicle is loaded with heavy loads in a cargo storage compartment.

In addition, damage fragments generated by the breakage of the close contact of the spikes are scattered by the rotational force of the double wheel to hit the vehicle directly, causing damage to the vehicle, and on both sides and the rear side of the vehicle using the vehicle anti-skid device. There is a problem that a large accident occurs due to sudden protrusion driving to avoid damage to the vehicle and broken fragments scattered to other vehicles running.

In addition, when the insertion ends of the spikes are broken, when the spikes are formed of a metal material and are cut, the cutting surface that is sharply formed comes into contact with the inner surface of the abdominal ring, which causes the accident that the abdominal ring is damaged and causes a large accident during driving.

In addition, the connecting rod connecting the vehicle anti-skid device is made of a metal material of the integral shape and the chain is pulled after the spike is first pulled due to the rotation of the double wheel, the connecting rod is broken by a sudden tension or vibration generated during the vehicle There was a problem that is broken.

On the other hand, due to the breakage of the connecting rod, the anti-skid device for the vehicle is dismantled from the double wheel and at the same time wound on the double wheel shaft where the double wheel is located, a situation in which the vehicle is difficult to proceed or scattered outside of the vehicle threatens damage and life to other vehicles in operation. There was a problem of increasing the incidence of accidents.

In addition, there is a problem that the binding port connecting the connecting rod and the chain is released by centrifugal force due to the rotation of the double wheel, and the damage occurs due to the same phenomenon as the connecting rod, so that the vehicle anti-skid device is released.

Therefore, the spike and the connecting rod does not scatter the debris even if the damage occurs due to the centrifugal force and ground vibration caused by the rotation of the double wheel, and the binding sphere is not loosened or broken so that the anti-skid device for the vehicle is prevented from being separated from the double wheel. In order to prevent damage to the vehicle and to prevent damage to other vehicles running on the road, there is an urgent need for an anti-slip device for automobiles.

Accordingly, the present invention has been devised in view of the problems of the prior art as described above, and can be applied in various ways depending on the state of the road surface where the double wheels are grounded using spikes formed in various structures, thereby increasing versatility. The purpose is to serve the planet.

In addition, another object of the present invention is to prevent the debris scattered even if the breakage occurs by forming a separation prevention wire and a double-layered spike to prevent complex accidents can protect the abdominal ring It provides an anti-slip device for cars that can prevent accidents caused by damage and breakage of the vehicle.
