Here, the longitudinal direction length of the internal pressure sensor 10 is a, the width direction length is b, and the thickness is h.

  The internal pressure sensor 10 is used, for example, in a tire pressure monitoring system (TPMS: Tire Pressure Monitoring System). In TPMS, the internal pressure sensor 10 measures the air pressure in the tire and this information is electronically transmitted to the receiving module. When the air pressure falls below the appropriate value, the driver is notified by a signal lamp on the instrument panel.

  In the present embodiment, the internal pressure sensor 10 will be described as an example. However, the electronic component attached to the attachment member 20 is not limited to the internal pressure sensor 10 and may be other sensors such as a temperature sensor, as long as the electronic component is attached to the tire. It doesn't matter what kind.

(Mounting member)
Next, the attachment member 20 will be described. The attachment member 20 is attached to an arbitrary place on the inner wall surface of the tire in order to attach an electronic component to the inside of the tire. FIG. 3A is a plan view of the attachment member 20 before the internal pressure sensor 10 is attached, and FIG. 3B is a cross-sectional view taken along the line AA in FIG.

  The attachment member 20 is made of a sheet-like rubber, and extends to both ends of the board portion 20a attached to the tire and the inner side in the tire radial direction of the board portion 20a and covers from both sides of the inner pressure sensor 10.

It is fixed apart.

(Pneumatic tire manufacturing method)
Next, the manufacturing method of the pneumatic tire 100 which attached the attachment member 20 which concerns on this embodiment is demonstrated. As a manufacturing method of the pneumatic tire 100 to which the mounting member 20 is attached, in the first manufacturing method in which the mounting member 20 is attached using an adhesive after the pneumatic tire 100 is manufactured, and in the vulcanization process of the pneumatic tire 100 The 2nd manufacturing method which attaches the attachment member 20 is mentioned.

  First, the 1st manufacturing method using an adhesive agent is demonstrated.

  First, the attachment member 20 as shown in FIG. At this time, first, a plate-shaped rubber made of a sheet-like member is prepared, and a release agent or a release sheet as a release member is applied or pasted from both ends to predetermined positions. And the hole 20c which fits the fastening part 10a formed in the internal pressure sensor 10 in the position where the said release member is attached is produced | generated.

  On the other hand, the pneumatic tire 100 is manufactured. The pneumatic tire 100 can be manufactured, for example, as follows by a normal process. That is, a rubber composition is prepared, and this rubber composition is affixed on an unvulcanized base portion that has been affixed in advance to the crown portion of the raw pneumatic tire case. And it manufactures by carrying out the vulcanization molding under the predetermined temperature and the predetermined pressure with a predetermined mold.

  Next, the produced attachment member 20 is affixed inside the tire center centering on the tire equator line of the manufactured pneumatic tire 100 using an adhesive.

  Next, the 2nd manufacturing method which attaches the attachment member 20 in the vulcanization | cure process of the pneumatic tire 100 is demonstrated.

  First, similarly to the first manufacturing method, the attachment member 20 as shown in FIG. At this time, first, a plate-shaped rubber made of a sheet-like member is prepared, and a release agent or a release sheet as a release member is applied or pasted from both ends to predetermined positions. And the hole 20c which fits the fastening part 10a formed in the internal pressure sensor 10 in the position where the said release member is attached is produced | generated.

  Next, the pneumatic tire 100 is manufactured. That is, a rubber composition is prepared, and this rubber composition is affixed on an unvulcanized base portion that has been affixed in advance to the crown portion of the raw pneumatic tire case. At this time, the produced attachment member 20 is disposed in a portion on the inner side of the tire center centered on the tire equator line with the surface on which the release member is attached facing the inner wall surface of the tire.

  Next, the green tire on which the mounting member 20 is arranged is vulcanized and molded with a predetermined mold at a predetermined temperature and pressure, and the mounting member 20 is welded to the tire.

(Modification)
The mounting member 20 according to the present embodiment has been described in FIG. 1 as being mounted in a direction in which the pair of covering portions 20b are arranged in the tire width direction. However, as shown in FIG. You may attach in the direction which arrange | positions 20b.

(Action and effect)
Since the mounting member 20 according to the present embodiment uses a flexible flat rubber material, it can be easily bonded to the tire inner wall surface. Thus, since the internal pressure sensor 10 is mounted inside the tire, the tire bead portion does not press the internal pressure sensor when the tire is assembled to the rim, and the internal pressure sensor is prevented from being damaged.

  Moreover, the attachment member 20 according to the present embodiment has the internal pressure sensor 10 disposed on the inner side in the tire radial direction of the substrate portion 20a, and covers the internal pressure sensor 10 from both sides by the covering portion 20b. And the internal pressure sensor 10 can be fixed reliably by making the fastening part 10a of the internal pressure sensor 10 penetrate the hole 20c of the attachment member 20. At this time, the bending stress as the restoring force of the covering portion 10b of the attachment member 20 acts in the circumferential direction (arrow B direction) of the attachment member 20, so that the internal pressure sensor 10 is at a certain distance (H) from the substrate portion 20a. It is fixed apart.

  Further, since the mounting member 20 according to the present embodiment has the reinforcing material 22, when the fastening portions 10 a on both side surfaces of the internal pressure sensor 10 are fitted in the holes 20 c of the mounting member 20, the bending strength of the reinforcing material 22 ensures more certainty. The internal pressure sensor 10 can be fixed at a certain distance from the tire.

  Moreover, when attaching the attachment member 20 which concerns on this embodiment, and the pneumatic tire 100, the adhesion | attachment by an adhesive agent or the welding by the vulcanization | cure at the time of tire manufacture may be sufficient. Thus, the attachment member 20 according to the present embodiment can be reliably attached to the pneumatic tire 100 by a simple method.

  In addition, when attaching by vulcanization, it is preferable that the attachment member 20 has a flat plate shape so that it may be deformed by the pressing force of the vulcanization bladder.

  In addition, when the height in the tire radial direction of the substrate portion 20a of the mounting member 20 is T, the length in the tire width direction of the bonding surface of the substrate portion 20a is W, and the distance between the two holes 20c is L, the length of the internal pressure sensor 10 is increased. It is preferable that the length in the direction is a, the length in the width direction is b, the thickness is h, and the following conditions are satisfied.

0.5h ≦ T ≦ h ...... Formula (1)
0.6b ≦ W ≦ 2.0b (2)
3a ≦ L ≦ 4a ...... Formula (3)
If T is smaller than 0.5 h, the circumferential bending rigidity of the mounting member will be insufficient, the internal pressure sensor 10 will not float, causing contact with or damage to the inner liner. If T is larger than h, the circumferential direction of the mounting member The bending rigidity becomes too large, requiring a great deal of force for mounting, and is not convenient.

  If W is smaller than 0.6b, the bending rigidity of the mounting member in the circumferential direction is insufficient, and the internal pressure sensor 10 does not float, causing contact with or damage to the inner liner. The circumferential bending rigidity of the member becomes too large, requiring a great deal of force for attachment, and is not simple.

  Also, if L is smaller than 3a, the internal pressure sensor 10 will not float and may cause contact with or damage to the inner liner. If L is larger than 4a, the fixing becomes loose, and the movement of the internal pressure sensor 10 is caused during tire rolling. The measurement accuracy of the internal pressure sensor 10 deteriorates.

  EXAMPLES Next, although an Example demonstrates this invention further in detail, this invention is not limited at all by these examples.

  In order to confirm the effect of the present invention, pneumatic tires according to Examples 1 to 4 and Conventional Example 1 were prototyped. The size of each test tire was 11R22.5. The mounting position of the internal pressure sensor was inside the tire center centered on the tire equator line.

  In Examples 1 to 4 and Conventional Example 1, all the internal pressure sensors having the same weight (8 g) were attached. The internal pressure sensor 10 used had a longitudinal length a of 30 mm, a width direction length b of 30 mm, and a thickness h of 6 mm.

  In the pneumatic tire according to Conventional Example 1, the internal pressure sensor was attached to the tire inner wall surface directly using an adhesive.

  The pneumatic tire according to Example 1 is obtained by pasting the attachment member 20 shown in FIG. 6 on the inner wall surface of the tire. When the tire is pasted using an adhesive, the pneumatic tire is pasted in the vulcanization process at the time of tire manufacture. There are two types of cases. The height T in the tire radial direction of the substrate portion 20a of the mounting member 20 according to Example 1 was 5 mm, the length W in the tire width direction of the bonding surface of the substrate portion 20a was 20 mm, and the distance L between the two holes 20c was 110 mm. .

  The pneumatic tire according to Example 2 is obtained by pasting the attachment member 20 shown in FIG. 7 on the inner wall surface of the tire. When the tire is pasted using an adhesive, the pneumatic tire is pasted in the vulcanization process at the time of manufacturing the tire. There are two types of cases. In order to improve the bending rigidity and reduce the weight of the covering portion 20b that lifts the internal pressure sensor, the thickness of the second embodiment is more distributed than that of the first embodiment. The tire radial direction height T, the tire width direction length W, and the distance L between the two holes 20c are the same as in the first embodiment.

  The pneumatic tire according to Example 3 is obtained by pasting the attachment member 20 shown in FIG. 8 on the inner wall surface of the tire. When the tire is pasted using an adhesive, the pneumatic tire is pasted in the vulcanization process at the time of manufacturing the tire. There are two types of cases. In order to make the adhesion to the tire more reliable, Example 3 has a wider area of the adhesion surface (substrate part 20a) than Examples 1 and 2. The tire radial direction height T was 5 mm, the tire width direction length W was 50 mm, and the distance L between the two holes 20 c was 110 mm.

  The pneumatic tire according to Example 4 is obtained by pasting the attachment member 20 shown in FIG. 9 on the inner wall surface of the tire. The pneumatic tire is pasted in the vulcanization process at the time of tire production when pasted using an adhesive. There are two types of cases. In order to improve the bending rigidity, to reduce the weight of the covering portion 20b that lifts the internal pressure sensor, and to ensure the adhesion to the tire, the fourth embodiment has a thickness distribution as compared with the first embodiment. Compared with 2 and 2, the area of the bonding surface (substrate part 20a) is made wider. The tire radial direction height T, the tire width direction length W, and the distance L between the two holes 20c are the same as in Example 3.

  The test was conducted by examining the presence or absence of peeling of the internal pressure sensor when the tires according to Examples 1 to 4 and Conventional Example 1 were mounted on the drive wheels of a vehicle having an axle type of 2-D4 and traveled 100,000 km. went.

The conditions and test results of Examples 1 to 4 and Conventional Example 1 are shown in Table 1.

  In Conventional Example 1, peeling of the internal pressure sensor occurred, but in Examples 1 to 4, no peeling occurred. For this reason, according to the present invention, it has been found that the sensor can be reliably and easily fixed to the inside of the tire without damaging the sensor.

  In addition, the time required for attaching the attachment member 20 is shortened in the case of welding in the vulcanization process than in the case of attaching with an adhesive. For this reason, it turned out that manufacture of a tire will become still easier if the attachment member 20 is welded in a vulcanization process.
