Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an anti-slip device mounted in a gap between a pair of two-wheeled tires, which can be quickly attached and detached like a steel tire chain, and can be fixed at equal intervals in the tire gap. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lashing method and a lashing device that allow replacement of parts only at the repaired portion.

[0002]

2. Description of the Related Art A tire belt (Japanese Patent No. 2544254) is shown as an anti-slip device to be mounted in a gap between two-wheeled tires. The vehicle vibration does not increase with the increase in
h and an anti-slip tool that generates vibration equivalent to that of a steel tire chain when the vehicle is stopped from 15 km / h when decelerating. Also, most of the load on the vehicle depends on the tire itself mounted on the vehicle, so the spike pin embedded in this anti-slip device is relatively small compared to the drag on the spiked tire . However, as a method of connecting only these tire belts, a female thread pipe was passed through the through hole of the tire belt, eye bolts were attached to both ends, and the eye bolts were connected with spring hooks and ring chains. It is difficult to remove the tire, and the running noise caused by the looseness of the ring chain is equivalent to that of a steel chain, and the tire belt itself has a disadvantage of relatively rotating and moving within the gap between the two wheels.

In order to prevent the relative rotational movement of the tire belt, bolts are welded to the iron discs having the same dimensions as the hub holes and bolt holes of the tire wheel at the same positions as the decorative holes, and the tire belt is penetrated. When another hole was made and fixed with a ring chain, the running distance increased to 600 km, but the wear and noise of the ring chain were not improved.

Therefore, instead of a ring chain, a metal wire is passed through a through hole of a tire belt, and a steel pipe with a flange is pressed by a hydraulic press to fix the tire belt to the metal wire. Although it is difficult to install them at equal intervals, the noise during running has been reduced, but due to the difference between the dynamic load radius and the static load radius of the tire, bending stress is repeatedly generated in the metal wire used to connect to the iron disk, The wire was worn and all the crimped steel pipes had to be cut off with a sander and reconnected, leaving much time for repairs.

[0005] Further, the shorter the attachment interval of the tire belt, the shorter the length of the metal wire connecting the tire belt, so that the displacement per length increases, and the possibility of wear due to repeated bending is high. The number of attached belts could not be increased to eight or more.

[0006]

When the tire belt first comes into contact with the two-wheeled tire and comes out of the ground with the two-wheeled tire, the force pinched by the sidewall of the two-wheeled tire is weak, and the dynamic load radius and the applied load are reduced. Due to the difference from the radius, a force that pushes up from the road surface acts on the tip of the ground of the tire belt, and this force is considered to be the cause of relative rotational movement in the gap between the two wheels, and the tire belt is bolted to an iron disc. It is considered that the clamped metal wire is compressed in the longitudinal direction, which causes the wire to wear due to repeated bending stress.

[0007]

Means for Solving the Problems By tapering both ends of a portion where the tire belt 1 comes into contact with the ground and a portion coming out of the ground so as to be parallel to the road surface, the pushing force from the road surface is reduced, and the tire belt 1 The shape of the tire belt 1 is changed so as to prevent uneven wear of the spike pins 20 driven at both ends.

The tire belt 1 can be fixed at equal intervals by using a roller chain 8 instead of a metal wire to connect the tire belt 1 and the mounting steel disk 4 and using a chain pitch. , Can absorb the pushing force from the road surface.
