Definitions
- the present invention relates to a slip-proof pin unit embedded in a tire to prevent a slip when a vehicle starts or stops on a snow-covered road, and a slip-resistant tire using the same.
- Snow II has multiple spikes (also referred to as studs) in a snow tire to ensure the safe driving of vehicles on snowy roads.
- equity is used.
- This studless tire is a kind of snow tire and is used at low temperature.
- a special compound rubber that is difficult to cure, and by cutting many unique narrow grooves (multi-sizing)
- the contact area with the road surface is increased, and irregularities on the ice are wrapped, and friction resistance is increased. It is a thing.
- the frictional resistance is not inferior to that of the spiked tire, but as the surface temperature approaches 0 ° C, the frictional resistance between the tire and the road surface decreases.
- the performance of the tire varies due to the condition of ice and snow.
- An elastic body 3 made of a material such as rubber is arranged in the cylinder 2, and a shaft 3 a formed in the center of the elastic body 3 is penetrated by a shaft 5 a in the middle of the spike pin 5. ing. Then, the rear end of the spike pin 5 is secured to the bottom of the cylinder 2. An enlarged neck 6 is formed at the tip of the spike pin 5, and the enlarged neck 6 protrudes beyond the opening edge of the tip of the cylinder 2.
- the shaft of the spike pin 5 is made thicker, the diameter of the cylinder 2 supporting the elastic body 3 increases, and the spike's own weight also increases.
- the rubber material or the like serving as the elastic body 3 is interposed between the cylinder 2 and the spike pin 5 as in the above-described conventional invention, the swing of the spike drum 5 is adjusted. In such a case, the rubber material may be caught between the jaw of the enlarged diameter neck 6 and the opening edge of the cylinder 2 due to the swing of the spike pin 5.
- the rubber material is deformed due to frequent swings of the spike pins 5, and it is likely that the spike pins 5 cannot be returned to the center, and the elastic body 3 lacks in durability and stability. I was
- spike pins are made to protrude using a shape memory alloy, but there are problems in performance, price, and durability, and they have not been put to practical use.
- the present invention provides a plurality of anti-skid pin units embedded in a tire and a plurality of anti-slip pin units that can adjust the action of the anti-skid pins on the road surface according to the difference in the friction coefficient of the road surface depending on the road surface condition.
- the purpose is to provide an anti-skid tire with a buried hole.
- the present invention has the following configuration in order to solve the above problems. That is, the tip of the anti-slip pin is projected and embedded in a hole formed in the outer surface of the tire to provide an anti-slip effect. Are provided at predetermined intervals in the circumferential direction, and the inner edge of the end opening end face is formed in the locking portion, and the cylinder is embedded in a hole formed in the outer surface of the tire.

- the cylinder is prevented from falling out and freely reciprocates in the cylinder in the direction of its axis, and when the cylinder is inclined with respect to the axis of the cylinder in the cylinder, the locking portion of the cylinder locks on the outer periphery.
- An anti-slip pin that controls the immersion of the cylinder.
- a biasing means such as a spring, which is disposed in the cylinder and biases the anti-slip pin from behind the retaining portion so that the tip of the anti-slip pin projects from the opening edge of the cylinder. It is characterized by.
- the anti-skid tyre is formed by embedding the anti-skid pin unit formed as described above into a plurality of holes formed in the outer peripheral surface of the tire.
- the anti-slip pin touches the road surface, the anti-slip pin is split due to the weight of the vehicle body. Is pushed into the cylinder against the urging force of the ring. Then, when the grounding state of the anti-slip pin with the road surface is released, the retaining portion at the rear end of the anti-slip pin is urged by a spring or the like, and the tip of the anti-slip pin projects from the tire surface.
- the pull-out portion at the rear end of the anti-slip pin is urged by an urging means, a rubber material or the like as an elastic body is used between the cylinder and the anti-slip pin as in the conventional case. There is no need to intervene, and the elastic body is not damaged. In addition, since no elastic body is interposed between the anti-skid pin and the cylinder, the diameter of the anti-skid pin can be increased and sufficient strength can be obtained without increasing the diameter of the cylinder.
