The present invention relates to a snow chain for a two-wheeled vehicle, and more particularly to a snow chain for ensuring a stable running of a two-wheeled vehicle vulnerable to the running of slippery surfaces such as snow roads and ice roads.

Motorcycles, such as motorcycles and bicycles, are means of transportation that move people and objects using the power or manpower of an engine.

Such a two-wheeled vehicle has a configuration in which the front and rear wheels arranged in a row are coupled to the frame. The front wheel is responsible for the steering function of the two-wheeled vehicle to advance the two-wheeled vehicle in the desired direction by the user's operation, the rear wheel is rotated by the power or manpower of the engine is responsible for the driving function of the two-wheeled vehicle.

The two-wheeled vehicle having this configuration is inclined in the horizontal plane inclined in the horizontal direction toward the steering direction during steering, so the rear wheels ideally point contact with the ground in consideration of running stability when tilted, and in fact very small area Surface contact (hereinafter, for convenience of description, 'face contact' is also referred to as 'point contact').

Therefore, the two-wheeled vehicle is to be moved by the friction force at the point contact point in front of the front wheel and the rear wheel in contact with the ground.

On the other hand, since the surface friction coefficient is small in the length of snow accumulation and the ice road, the running of a motorcycle becomes dangerous.

Hereinafter, a driving state of a general bicycle will be described with reference to FIG. 6.

6 is a side view illustrating a snowy driving state of a general bicycle.

As shown, when the snow 30 is accumulated on the ground 40, the bicycle 10, which is a two-wheeled vehicle, is not normally transmitted to the driving force of the rear wheel 20 by a small surface friction coefficient by the snow 30. However, even when stopped, the front wheel 16 and the rear wheel 20 slide along the snow 30, and thus a long braking distance occurs, so that a safe driving cannot be guaranteed.

To solve this problem, the method as shown in Fig. 7 was used.

FIG. 7 is a side view illustrating a main part of a state in which a pneumatic pressure of a tire wheel is lowered to prevent slippage on a snowy road in a general bicycle; FIG.

As shown in Fig. 7, in order to compensate for unstable driving / braking by snow or ice, a method of lowering the air pressure of air filled in the tire 12 was used.

As such, when the air pressure of the tire 12 is lowered, the area in which the tire 12 is in contact with the ground becomes large, and thus the grip force may be improved.

However, the improvement of the traction force according to this method is not effective, and since the air pressure of the tire 12 needs to be restored to the normal value again, there is a problem of inconvenient use.

The present invention is derived to solve the problems according to the prior art described above, it is an object of the present invention to provide a snow chain that can ensure the stable running and braking of two-wheeled vehicle on the snow road or ice road.

Another object of the present invention is to provide a snow chain that is easy to install and detach and is applicable to tires of various sizes.

In order to achieve the above object, a snow chain for a two-wheeled vehicle according to an embodiment of the present invention, in the snow chain for two-wheeled vehicle that is coupled to the wheel of the two-wheeled vehicle to provide the friction force necessary for running, the outer periphery of the tire constituting the wheel A friction band portion wrapped along; And a fixed band part coupled to both sides of the friction band part and having a length adjustable to wrap along an outer circumference of the rim constituting the wheel.

In the present invention, the friction band portion: a metal wire wound with a plurality of iron wires; And friction springs coupled along the outer circumference of the metal wire.

In the present invention, tubular reinforcement terminals coupled at predetermined intervals along the outer circumference of the friction spring; may be further coupled.

In the present invention, the fixing band portion: two wire hook pieces coupled to both ends of the metal wire, one side is bent to form a ring portion; Two connecting pieces fitted to the ring portions of the wire hook pieces; And one side has an open ring shape, both ends are Velcro tape is coupled, the length adjustment band is coupled to the connecting piece; may include.

In the present invention, the friction band may be formed of a soft synthetic resin band having a length adjusting band hook hole at both ends.

In the present invention, a plurality of spikes may be further coupled to the surface of the flexible synthetic resin band to rub against the ground.

In the present invention, the length adjustment band, one side has an open ring shape, both ends of the Velcro tape is coupled, it can be coupled to the adjustment band hook hole.

In the following, embodiments of the present invention are described with reference to the accompanying drawings.

In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted. In addition, the terms to be described later are terms set in consideration of functions in the present invention, and these terms may vary depending on the intention or custom of the producer producing the product, and the definition of the terms should be made based on the contents throughout the present specification.

(First embodiment)

First, a snow chain for a motorcycle according to a first embodiment of the present invention will be described with reference to FIG. 1.

1 is a perspective view of a snow chain according to a first embodiment of the present invention.

As shown, a snow chain for a motorcycle according to a first embodiment of the present invention (100: unless otherwise described for convenience of the description below, the 'wheel chain for motorcycles' is simply referred to as 'snow chain') It is largely composed of a friction band part and a fixed band part.

The friction band portion wraps along the outer periphery of the tires constituting the wheels of the motorcycle and provides the friction force necessary for stable driving and braking of the motorcycle on snow or ice roads.

The friction band portion includes a metal wire 140, a friction spring 150, and a reinforcing terminal 160.

The metal wire 140 is formed by winding a plurality of iron wires.

The friction spring 150 is coupled along the outer circumference of the metal wire 140 to generate frictional force necessary for driving and braking the motorcycle by rubbing with snow or ice.

The reinforcing terminal 160 has a tubular shape and is coupled at predetermined intervals along the outer circumference of the friction spring 150 to prevent the friction spring 150 from being deformed by the weight of the motorcycle and the occupant.

The fixed band part is coupled to both sides of the friction band part, and wraps along the outer circumference of the rim constituting the wheel, thereby helping the snow chain 100 to be stably coupled to the motorcycle.

The fixing band part includes a wire hook piece 130, a connection piece 120, and a length adjusting band 110.

Wire hook piece 130 is coupled to both ends of the metal wire 140, one side is bent to form a ring portion 134. The metal wire 140 is engaged with the wire through hole 132 formed in the wire hook piece 130.

The connecting piece 120 has a rectangular ring shape that is fitted to the ring portion 134 of the wire hook piece 130.

The length adjustment band 110 has an annular shape with one side open, and both ends of the Velcro tapes 112 and 114 are coupled to each other and are coupled to the connection piece 120.
