JPS62273105A - Anti-skid wheel for tire of automobile and the like - Google Patents

Abstract

PURPOSE:To obtain easy attaching/detaching of the captioned wheel and improve the riding comfort and to prevent the road from being damaged, by enabling a hollow ring-body, in which spokes the tips of which are provided each with a projected plate are arranged via an elastic member in such a manner that the spokes can freely go forward or backward, to freely be attached to or detached from a tire wheel side-surface. CONSTITUTION:By using a bolt 7, a hollow ring-body 16 is attached to the side-surface of a tire wheel 17. The pneumatic pressure of a rubber tube 3 is adjusted, according to the road-surface condition. With this, a projecting plate 18 is projected from the ground-touching surface of a tire 10, cutting into the ground. In addition, a spoke 4 goes back, according to the deformation of the tire 10, which conforms to irregularity of the road surface, and pushes a rubber tube 3. As a result, the pneumatic pressure in the rubber tube 3 increases, thereby increasing the touching area between the tire 10 and the ground. With this constitution, the anti-skid performance can be enhanced, the riding comfort can be improved, and the damage to the road surface can be prevented.

Description

Detailed Description of the Invention 3. Detailed Description of the Invention (Field of Industrial Application) The present invention relates to an anti-slip wheel for a tire that is attached to and detached from the side surface of a tire wheel of an automobile or the like.

(Conventional technology) Tire chains and spiked tires are used to prevent tires from slipping when driving on snowy or icy roads, but both have many problems. The current situation is that people have no choice but to use tire chains because there are no effective alternatives.

Normal tires are fine, but each time they are installed or removed, the vehicle body must be jacked up alternately, and they cannot be installed smoothly, and abnormal noises and vibrations may be generated while driving, and they are not very effective in preventing skidding. In addition, when using spiked tires, it is necessary to prepare a separate spiked tire in addition to the standard one, and to attach and detach it, it is necessary to jack up the car body, loosen and tighten the hub nuts, and it is not possible to easily attach and detach it as necessary. I can't. In particular, spiked tires damage the road surface and cause environmental pollution due to their dust, which has developed into a social problem, and there is a strong demand for improvement.

<Means for Solving the Problems> The present invention was provided in order to solve the above-mentioned conventional problems, and its structure includes a hollow 11-ring body that can be attached to and detached from the side surface of a tire wheel with bolts or the like. A plurality of spokes are guided by the hollow ring body so that they can move forward and backward in the radial direction, and each spoke has a protruding plate at its tip. It is composed of an elastic member that elastically suppresses the spoke in the forward direction.

Effects> The present invention is characterized in that the protruding plates at the tips of a plurality of spokes provided on a hollow ring body attached to the side surface of a tire wheel with bolts are pressed by the bullet part K and touch the snowy road or frozen road surface. Has a non-slip effect.

<Example> Hereinafter, an example of the present invention will be described based on the drawings. In FIGS. 1 and 2, 10 is a tire of an automobile equipped with a wheel 17#. The anti-slip wheel according to the present invention is removably attached to the wheel 171ζ of the tire 10.

The structure includes a hollow ring body 16 consisting of an inner case 1 and an outer case 2, and a plurality of spokes 4 guided in spoke grooves 9 that can move forward and backward in the radial direction (radial direction) #ζ. , a projection plate 18 provided at the tip of the spoke 4, and the hollow ring body 16
A resilient member for pressing the spokes 4 in the outer diameter direction is provided in the hollow portion of the spoke. This elastic member may be a spring (not shown), but as shown in the figure, a rubber tube 3
The rubber tube 3 is filled with appropriate air pressure via the air valve 8, and the rear ends of the spokes 4 are brought into contact with the rubber tube 3 and pressed elastically by the air pressure of the rubber tube 3. A structure that does this is appropriate. In addition, 5 is a rubber cover surrounding the tips of the spokes 4, 6 is a circle-shaped spring that connects a plurality of spokes 4 in series, 11 is an oil groove for supplying oil to the sliding part of the spokes 4, 12. Reference numeral 13 indicates a connecting bolt between the inner case 1 and the outer case 2.

The hollow ring body 16 having the above structure is the wheel 1 of the tire 10.
The hollow ring body 16 can be attached concentrically to the outer surface of the wheel 17 by fixing the hollow ring body 16 directly to the wheel 17 with bolts 7, or as shown in FIG. 14 is fixed with bolts 15, and this sub-ring 141ζ hollow ring body 16 is fixed with bolts 7.

Next, the operation of the present invention with the above configuration will be explained. First, the air pressure of the rubber tube 3 is adjusted in accordance with the road surface condition, similar to the tire lO. For example, when the ice is hard or there is a lot of snow, the air pressure is increased when it is desired to force the protrusion plate 18 to bite into the ice more strongly. This is E Koyori spoke 4
is pushed out with a strong force in the direction of the outer diameter. However, since the amount of protrusion is stopped by the inner circles of the inner case 1 and outer case 2, the protrusion plate 18 is smaller than the diameter of the ground contact surface of the tire 10.
Only about the thickness of is projected.

When the tire 10 collapses due to the weight of the car or the surface of the road, the spokes 4 retreat according to the amount of deformation of the tire IO and press the rubber tube 3, causing the rubber tube 3 to deform by that amount, as shown in Figure 83. The air pressure also increases, and the contact pressure with the road surface increases even more. At this time, there are at least two protruding plates 18 that touch the ground to prevent rotation and lateral slipping of the tire 10.

Furthermore, the spokes 4 are always pushed out in the outer radial direction by the centrifugal force of the rotation of the tire 10, but if a certain amount of pressure exists within the rubber tube 3, they are arranged on the same circumference.

When the anti-slip device is no longer needed after passing through an icy or snowy road, the hollow ring body 16 can be easily removed from the wheel 17.

Since the spring 6 pulls the spokes 4 toward the center of rotation, the vehicle can run even when the hollow ring body 16 is attached to the wheel 17. Projection plate 18 at this time
do not come into contact with the road surface, and even if fζ does come into contact, it will not create a strong contact pressure that scrapes the road surface like spiked tires.

<Effects of the Invention> As described above, according to the present invention, the anti-slip wheel can be easily attached to and detached from the tire wheel without jacking up the vehicle body. In addition, the ground pressure of the protrusion plate is adjusted by adjusting the elastic force of the rubber tube, etc. to adjust the digging force according to the frozen road surface and amount of snow, providing an appropriate anti-slip function, and providing a good grip with no abnormal noise or vibration. You can drive comfortably. Furthermore, it has the beneficial effect of eliminating cutting and tearing of the paved road surface and solving problems such as dust.
