Description

Caterpillar snow chains {Caterpiller type snow chain for vehicle}

The present invention relates to a snow chain for a vehicle that can be used on an ice road or a snow road in winter, and more specifically, an endless track type which is installed along the outer circumferential surface of a tire in an endless track type so as to exhibit strong braking force and climbing capability in any environment. It's about the chain.

Snow chains have been provided in various forms as winter equipment for various vehicles. In the development of snow chains, the important task is to be convenient and quick to install, to be safe for use, and to be lightweight and durable.

Common snow chains, such as wire chains or polyurethane chains, have not had a satisfactory effect on snow or ice. In other words, the conventional snow chain mounting is a rather formal dimension.

An object of the present invention for such a problem is to provide a new type of snow chain that can exert a definite effect even on snow and ice. To this end, the present invention proposes to apply the shape and principle of the caterpillar (caterpiller) that has been applied to heavy equipment or military vehicles to the snow chain of the vehicle. In applying this, the weight should not be excessively increased, it should be easy to install and use, and should be safe in use.

The above object is, a plurality of plates of the same shape, the one surface is in contact with the tire and the other surface is in contact with the road surface is connected in series so as to be the length of the circumference of the tire by the pin, flow or escape from side to side in the state covered on the tire Guide members are extended from left and right sides of the plates so as not to be included, and include a fixing member having elasticity connected between the guide members to maintain a state of being in close contact with the outer circumferential surface of the tire, and contacting the road surface during operation. The surface of the plate is achieved by a crawler type snow chain for a vehicle, characterized in that the blade is formed integrally projected so as to be perpendicular to the road surface.

Hereinafter, with reference to the accompanying drawings in the specification will be described in more detail.

1 is a perspective view illustrating a state in which a snow chain according to the present invention is unfolded.

In the snow chain 2 according to the present invention, a plurality of plates 4 having the same shape are connected in series so that the width becomes similar to the tire 1 and the length becomes similar to the circumference of the tire. An uneven portion 6 is formed on the upper surface of the plate in contact with the tire to prevent sliding.

Figure 2 (a) is a side view of a part of the snow chain according to the present invention, Figure 2 (b) is a front sectional view, Figure 2 (c) is a plan view. In particular, Figures 2 (a) and (b) show the tire being virtually added. Figure 2 (a) (c) shows one or more plates to clarify the connection of the plates.

On the upper surface of the plate 4, as described above, non-slip means such as the uneven portion 6 is formed, and on the lower surface, the blade 8 is formed vertically along its longitudinal direction. The blade 8 is formed to extend in a direction perpendicular to the straight direction of the vehicle. On both sides of the plate 4, the guide member 10 is formed to protrude in a direction perpendicular to the plate. The guide member 10 is a fixing means for preventing the left and right flow and deviation of the tire 1 mounted on the plate. The plate is hinged by pins 12. For this purpose, pinholes 14 are provided in front and rear of the plate. Since a method of fixing the pin in the pinhole can be used, a description thereof will be omitted.

As shown in FIG. 2 (b), a fitting hole 16 is formed in the middle of the guide member 10, which is part of a means for tightly fixing the chain to the tire. The description thereof will be described later. Both lower sides 18 of the blades are rounded as shown to avoid excessive resistance with the road surface.

As shown in Fig. 2 (a), there is a gush 20 is formed between the blade and the plate to reinforce their rigidity.

3 (a) and 3 (b) are a front view and a side view showing a tire in a state where a snow chain according to the present invention is installed. According to this embodiment, since the tire does not directly contact the road surface, propulsion force, braking force, etc. are transmitted through the plate and the blade. The length of the plate can be changed as needed. As a result, the spacing between the blades increases, and there is a fear that the effect of the chain also decreases. In addition, if too small, the increase in price will be a problem, but the effect is reduced noise.

4 is a use state diagram sequentially showing the installation state of the snow chain of the present invention. With the vehicle 30 stationary, the chain is placed over the tire 40 so that one end of the chain is positioned at the A point. Then, one end of the fixing member 22 with the hooks attached to both ends is connected to the point A, and the other end is connected to the point B adjacent thereto so as to be in the form of FIG. 4 (a). When the vehicle is driven straight in this state (when the tire rotates counterclockwise), the rest of the chain that is not caught by the tire 40 is placed on the tire. In this state, the fixing member 22 is further pulled to connect to the guide member of the appropriate plate 4. Thereby, it will be in the state of FIG.

5 is a configuration diagram of the fixing member described. Fixing member 22 is composed of a hook 24 is fixed to both ends and the elastic strap member 26 and a moving ring 28 that can be positioned at any position in the center. String member 26 is a high elastic material, its use has been described through FIG.

In the plate 4 according to the present invention, carbon plastic, aluminum alloy, or the like may be selectively used. Pros and cons of each material will be fully appreciated by those skilled in the art. The plate, in particular the blade, may be made of rubber. This will give the advantage of minimizing the damage of the road surface.

The above illustration and description are merely one embodiment according to the present invention. Therefore, those skilled in the art will be able to make various modifications within the scope of the present invention without departing from the spirit of the present invention. In particular, the blade may be a key point of the present invention may be changed in various shapes. For example, the bottom may not be flat but may have a symmetrically curved shape, may have a wave shape, or may have a gear shape. In addition, the pad may be provided in a form in which the pad is not the same material as the plate (spike type). As a result, the road surface may come into contact with the pad, thereby preventing damage to the road and the chain even when driving on snow-free roads. In addition, it is possible to form a variety of irregularities on both sides of the blade.

By such modification, various additional effects can be expected. Also in the shape and material of the other guide member, the plate, various modifications may be made as desired.

6 is a front view of the plate, in particular, showing an example of the shape that the blade 8 'may have. FIG. 6A illustrates a shape in which the grooves 40 having a constant size are recessed at regular intervals, and FIGS. 6B to 6C show an irregular shape in a state where the grooves 40 'and 40 "of the rhombus shape are balanced. 6D shows a state in which a plurality of semi-circular grooves 42 are formed. Thus, the blade is in direct contact with the road surface and is subjected to a large load or friction force, and thus varies according to the amount of snow or the road surface state. It would be desirable to be able to select and use it.

According to the above configuration, a snow chain for a vehicle in the form of a caterpillar, that is, a caterpillar, is provided. This type of driving method can assist the driving of the vehicle quite effectively on a snowy road. That is, even on snow or ice roads, the climbing ability and braking ability are strongly supported. In addition, the snow chain according to the present invention is preferable because it is easy to install.
