Abstract

PURPOSE:To prevent damage of a road surface and generation of dust, by providing a shape memory alloy between a head portion of a spike pin and a head portion of a guide pin, and biasing the spike pin with a spring. CONSTITUTION:A single-directional shape memory alloy 8 is in plastic condition at a low temperature, and a spike pin 3 is upwardly urged by a spring 7 to be projected from a surface of a tire 1, thus exhibiting a spike function. On the other hand, at a high temperature, the shape memory alloy 8 is rendered in a contracted condition, and accordingly the spike pin 3 is downwardly urged against a spring 7 which is thereby depressed, thus being retracted from the tire surface 1 and acting as a normal tire. With this constitution, damage and wear of a road surface may be prevented, and accordingly generation of dust may be suppressed.

徴としている。Focusing on the fact that the heat generated by a spiked tire while driving changes depending on the snow and snow conditions on the road, the system features an automatic adjustment mechanism for the protrusion of the spike pins according to the road's ice and snow conditions. be. That is, in the spiked tire of the present invention, a spike pin that can freely appear and retract on the ground contact surface and a guide pin that supports and guides the spike pin are arranged inside the tire body, and a distance between the heads of these spike pins and the guide pin is set. A wavy helical or coiled actuating member made of a shape memory alloy that expands and contracts into a memorized shape with temperature is exposed and connected to the surface of the spike pin head, and a center portion is cut out between the flange portions of these spike pins and the guide pin. It is characterized by a mechanism that can be deformed into an operating position in which the spike pin is held in a protruding state and a non-operating position in which the spike pin is held in a retracted state by inserting a plate spring, a disc spring, or a coil spring.

The spike pin 3 is pushed up by the force of the spring 7, and thus is shown in a state where it protrudes from the surface of the tire 1.

態を示している。FIG. 2 shows that at high temperatures, the unidirectional or bidirectional shape memory alloy 8 is in a contracted state, so the springs 8 are crushed, and the spike pins 3 are therefore submerged below the surface of the tire 1.

したことを特徴とするスパイクタイヤ。Inside the tire body, a spike pin that can freely retract from the ground contact surface and a guide pin that supports and guides the spike pin are arranged, and the shape between the spike pin head and the guide pin head is deformed into a memorized shape by temperature. The actuating member made of memory alloy is exposed on the surface of the spike pin head and connected, and furthermore, the flanges provided on the spike pin and the guide pin are formed with flat support surfaces facing each other, and a spring is inserted between both support surfaces. A spike tire characterized by having a mechanism that can transform the spike pin into an operating position in which the spike pin is held in a protruding state and an inoperative position in which the spike pin is held in a retracted state.
