Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tire heating device for preheating a tire of an auto racing machine immediately before the start of a race.

[0002]

[Prior art]

 In auto racing, stable cornering is not possible unless the tire surface temperature becomes high and the tires are not sufficiently soft. In other words, some time after the start of the race, until the tire surface temperature rises due to friction with the ground, the performance of the machine cannot be fully exerted. For this reason, the cooling of the tire was prevented by, for example, not cooling the entire machine. In the past, it was easy to heat a racing tire with the wheel removed from the wheel, but it was extremely difficult to heat the tire of a racing machine immediately before starting.

[0003]

[Problems to be solved by the device]

 In particular, tires for racing machines have a very large ground contact area, so when heating a racing tire with a heating device, etc., it is possible to effectively and easily heat up to the side of the tire. And how to attach and detach the heating device easily and quickly. In other words, it is the side of the tire that touches the ground in cornering, and we want to heat up just before the race.

[0004]

[Means for Solving the Problems]

 The present invention comprises a seat having a length that covers the entire circumference of the tire and a width that covers both side surfaces of the tire, and has a plurality of V-shaped notches formed at equal intervals on both sides corresponding to the both side surfaces. The tire band, the resistance heating wire that is arranged in a meandering shape in the tire band while avoiding the V-shaped notch, and is connected to an external power source, and is inserted into both side edges of the tire band. The problem described above is solved by providing a tightening string that tightens both side portions of the band along the both side surface portions of the tire.

[0005]

[Action]

 The device of the present invention can be easily mounted on both sides of the tire along the entire circumference, and the tire surface can be uniformly heated by energization.

[0006]

【Example】

 FIG. 1 is an exploded perspective view showing an embodiment of the tire heating device of the present invention, and FIG. 2 is a front and rear wheels (W) of a motor race machine in which the tire heating device shown in FIG. 1 is supported by a stand (S). ) Is a perspective view showing a state in which the device is attached to the device.

The tire warming device (1) comprises a tire band (2) made of a sheet such as polyester cloth as a main body, and its length is almost equal to the entire circumference of the tire requiring heating. The width is wide enough to cover both side surfaces of the tire.

A narrow wheel band (3) is attached to one end (2a) of the tire band (2) in the longitudinal direction in the width direction of the tire band (2). This wheel band (3) temporarily holds the end (2a) of the tire band (2) to which the wheel band (3) is attached by holding the wheel rim (4) over the tire. , The tire abdomen (radial direction), that is, the rim (4) is rotated once, and both ends have a sufficient length to overlap each other.

At both ends of the wheel band (3), hook-and-loop fasteners (5) and (6), which are usually called Velcro tapes, are provided on the loop surface and hooks of the hook-and-loop fastener when the band is looped. The wheels are attached to the front and back of the wheel band (3) so that they face each other.

At both ends of the tire band (2), the same surface fasteners (7) and (8) as described above are also arranged so that when the tire band (2) is looped, the loop surface and the hook surface are also faced to each other. , The tire band (2) is attached to both front and back positions. This is to wind the tire band (2) around the entire circumference of the tire to secure it.

On both side edges of the tire band (2), a plurality of V-shaped notches (9) having a length ranging from ¼ to ⅓ of the band width are provided at equal intervals. The V-shaped notches (9) on one side edge are staggered with the V-shaped notches (9) on the other side edge.

A resistance heating wire (10) is arranged on the entire surface of the tire band (2) in a meandering shape, avoiding a place where these notches (9) are provided. Both ends of this resistance heating wire (10) are drawn to the outside. The resistance heating wire (13) is preferably sewn between the fabrics of the tire band (2).

The edges of both sides of the tire band (2) are folded back to form a sack stitch (11) except at the notch (9), and the tightening cord (12) is sewn into the sack stitch (11). ) Is inserted. This is tightened in a purse-string shape so that both sides of the tire band (2) can be fitted along both sides of the tire.

The cord (13) formed by pulling both ends of the resistance heating wire (10) to the outside is connected to the transbox (3), and the transformer box (14) connects the power cord (15). Connected to the commercial power supply via. In the transformer box (14), a controller for temperature control and / or a microcomputer control section can be provided if desired.

In using the tire warming device of the present invention, first, the front and rear wheels (W) of the auto racing machine are supported by the stand (S) so as to float from the ground, and the tire band (2) of the tire warming device (1) is supported. ) Rotate the wheel band (3) at one end (2a) from the top of the tire around the back of the rim (4) and wrap it tightly, and attach the surface fasteners (5) (6) at that end to each other. Temporarily stop.

In this way, one end of the tire band (2) is temporarily fixed to the tire, so the wheel is rotated once in this state, and the other end (2b) of the tire band (2) is rotated. ) Is brought to a position adjacent to the one end, and then the surface fasteners (7) and (8) are attached to each other to fix the tire band (2) on the tire.

Then, both ends of the tightening string (12) on both side edges of the tire band (2) are hand-squeezed so that the side parts of the tire band (2) are firmly along the side parts of the tire. By doing so, the V-shaped notch (9) of the tire band (2) is narrowed down in a purse-string shape as shown in FIG. 2, and the tire is entirely covered.

Then, the plug of the cord (13) is inserted into the transformer box (14), and the power cord (15) of the transformer box (14) is inserted into the commercial power source. Turning on the power switch (16) of the transformer box (14) starts heating the tire. According to the preferred embodiment of the present invention, the surface temperature of the tire is heated to about 85 ° C. about 20 minutes after the power switch 16 is turned on.

[0019]

[Effect of device]

 According to the present invention, the tire can be mounted extremely easily. Further, by adopting a V-shaped notch and a tightening string, it is possible to fit both side portions of the tire band to both side surface portions of the tire so that they are in close contact with each other. Therefore, the heating of the tire is evenly performed over the entire side surface. Furthermore, the band can be removed very easily and at once, so it is possible to heat it sufficiently until just before the start of the course.
