Description

[Detailed Description of the Invention] A. Field of Industrial Application The present invention relates to a tire fixing device for fixing a vehicle during vehicle testing.

B. Summary of the invention This invention is a fixing device for fixing tires.
Instead of the chain that was conventionally attached to the tire, a ladder-like belt with a width that extends to the sides of the tire is used, which prevents damage to the tire and slight movement of the tire that would occur when using a chain, and ensures secure fixation. This is how it was done.

C. Prior Art As shown in FIG. 3, the following methods have been conventionally known as means for fixing a vehicle 4 in a predetermined position during a vehicle durability test or the like. As shown in FIG. 2, fixing members 51 and 52 are provided at the front and rear of the tire 10, and the fixing members 51 and 52 hold the tire 10 between them.
and the chain 54 passed between the tires 10 and 52.
The tire 10 is fixed by winding the chain 54 with a winding device 56 provided on the fixing member 52 side, thereby fixing the vehicle 4.

D Problems to be Solved by the Invention However, with such a fixing device 50, the chain 54 and the tire rubbed against each other due to vibrations of the vehicle 4 during the test, causing damage to the surface of the tire 10. Further, since the volume of the chain 10 becomes large when it is wound up, the winding device 56 provided inside the fixed member 52 has to be enlarged. In some cases, the fixing force of the tire 10 was insufficient because it could not be placed near the surface.

E. Means for Solving the Problems In the present invention, in order to solve the above problems, the tire fixing device is configured as follows. That is, a ladder-like belt having a width extending to the sides of the tire is provided between tire fixing members provided at the front and rear of the tire in the rolling direction, and the tire is fixed by hooking and pulling this belt around the tire.

F Example Embodiments of the present invention will be described below with reference to the drawings.

A tire fixing device 2 is shown in FIG. This tire fixing device 2 is attached to the front wheel 6 of a vehicle 4, as shown in FIG. 3, and the vehicle 4 is fixed on a testing device 8. Specifically, as shown in FIG. 1, the fixing members 12 are arranged at the front and rear, and these fixing members 12 are set on the floor 14 so as to be slidable in the front and rear direction, and the pair of fixing members 12 are installed in the vehicle. They are arranged in the same way on both sides so as to be located on the other side of the wheel of 4. A belt 16 is stretched between the fixed members 12, and one of the fixed members 12
A winding device 18 winds up this belt 16.
is provided. The belt 16 is a cloth-like member made of nylon or the like formed into a ladder shape as shown in FIG. It has a width that extends to the sides (not shown in Figure 1), and is wound up by the aforementioned winding device 18.

Therefore, when the vehicle 4 is fixed by the fixing device 2, since the front wheels 6 are wrapped around the belt 16, the belt 16 and the tires 1 of the front wheels 6 are
Even if rubbing occurs between the tires 10 and 0, no damage is caused to the surface of the tire 10. Furthermore, since the volume of the belt 16 does not increase so much even when it is wound up, the belt storage part in the winding device 18 can be made smaller, and the belt 16 can be made smaller than the tire 10.
Since the tire 10 can be placed near the tire 10, the adhesion of the tire 10 can be increased, the fixing force can be increased, and the tire 10 can be held down from the side, making it possible to securely fix the tire 10 more securely.

Note that the tire 10 may be fixed not only to the front wheel 8 but also to the rear wheel side.

G. Effects of the invention According to the tire fixing device of the invention, a ladder-like belt with a width that extends to the sides of the tire is used in place of the conventional chain, so that vibrations of the tire during use do not affect the tire surface. It does not cause damage, the belt winding device can be made smaller, the device can be made smaller and simpler, and the belt can be placed closer to the tire surface and can be suppressed to the side of the tire, reducing side slippage of the tire. This improves the adhesion of the belt to the tire and improves the fixing force.
