もワイヤスポーク車輪にチユーブ無しタイヤが使
用できない理由になつていた。 In conventional wire spoke wheels, the other ends of the wire spokes that are locked on the hub side are passed through the rim on the rim side, and are tightened and fixed with nipples. Because the locking holes for the wire spokes pass through the rim, it is said to be difficult to install tires without tubes. In addition, these wire spoke wheels have better cushioning properties than cast wheels, so they are used in motocross motorcycles, but due to severe impact, the mounting surface of the tire bead may slip on the bottom pressure contact surface of the rim. This creates a momentary gap between the tire and the rim, which causes air to leak. This is also the reason why tubeless tires cannot be used with wire spoke wheels.

特徴とするものである。 To achieve the above object, the present invention provides a wire spoke wheel for mounting a tubeless tire in which wire spokes are stretched between a rim and a hub, in which a rim region sandwiched between both bead portions of a tire mounted on the rim is closed off. At the same time, a raised part is formed in a portion that contacts the inner side of the bead part, a flange part is formed in a hollow structure, and a locking hole for locking the end of the wire spoke is provided at the bottom of the flange part. In addition, the present invention is characterized in that an opening is provided in the inner wall surface with which the bead portion comes into contact, and passes through the locking hole so as to face the locking hole.

る。 In Figures 2 to 7, 1 is a hub made of a light alloy such as an aluminum alloy or a magnesium alloy;
2 is a rim also made of light alloy. The hub 1 has locking portions 3, 3 that protrude like gears at both ends in the width direction, and the locking portions 3 have locking holes 3a, 3 at two upper and lower locations for locking the wire spokes 4.
A is provided. On the other hand, the rim 2 has flanges 5, 5 formed into hollow cylinders at both ends in the width direction, and a tire 7 without a tube is mounted so as to be sandwiched between the flanges 5, 5 (Fig. 4). ). In the rim 2, there is a region 2 corresponding to the air sandwiched between the bead portions 7a, 7a of the tubeless tire 7.
b has a non-porous closed wall structure, and this region 2b has raised portions 16, 16 provided along the circumferential direction at portions that contact the inner sides of the bead portions 7a, 7a.

ヤ7とリム2との間の滑り止めとして作用する。 A locking hole 5a for locking the end h of the wire spoke 4 is bored in the bottom surface of the flange portion 5 at both ends. Furthermore, an opening 6 is formed in the inner surface of the flange portion 5 to correspond to the locking hole 5a and penetrate through the hollow wall (FIG. 5). This opening 6 serves as an insertion port for assembling the wire spokes 4, and also acts as a non-slip between the tire 7 and the rim 2 when a tire 7 without a tube is mounted.

を確実なものにする。 The wire spokes 4 are composed of a central spoke 4c bent into a crank shape, and linear outer spokes 4s connected to both ends of the central spoke 4c, and the spoke diameter of the outer spokes 4s is smaller than that of the central spoke 4c. There is. The outer spokes 4s have their end portions h locked in one of the locking holes 5a provided in the flange portion 5 of the rim 2, and extend obliquely toward the opposite side in the width direction, and the extended end portions are connected to the opposite side in the width direction. It is connected by a connecting tool 8 to the end of the central spoke 4c that is locked to the locking part 3 on the side hub 1. This connector 8 is of a turnbuckle type in which both ends are threaded in opposite directions.
The outer spokes 4s that are locked in the locking holes 5a of the flange portion 5 on the opposite side are also obliquely crossed on the opposite side in the width direction in the same manner as above, and are locked in the locking portion 3 on the opposite end of the hub 1. The connecting member 8 is connected to the central spoke 4c. The end h of the outer spoke 4s has an oval shape as shown in FIG. 6, and is therefore engaged in a hollow groove in the hollow cylindrical flange 5 to prevent rotation. Therefore, the tightening by the connector 8 is ensured.

しタイヤ7の装着が可能になる。 In the wire spoke wheel described above, the rim region 2b sandwiched between the bead portions 7a, 7a of the tubeless tire 7 has a non-porous closed wall structure.
No air leaks occur. In addition, since the ridge 16 is provided in contact with the inside of the bead 7a, even if the tire 7 receives a severe impact while driving, as in the case of a motocross motorcycle, the bead 7a will remain in contact with the ridge 16. This prevents inward deformation. Therefore, there is no possibility that a gap will be formed between the bead portion 7a and the rim 2 and air leakage will occur. Therefore, it is possible to mount the tire 7 without a tube even on a wire spoke wheel.

ヤの装着性を向上することができる。 Further, a flange portion 5 having a hollow structure has a locking hole 5a for locking the end of the wire spoke 4 to the rim 2.
The wire spokes 4 can be attached without air leakage. In addition to this locking hole 5a, the locking hole 5 is also provided at a portion where the bead portion 7a of the tire 7 contacts the inner wall surface of the flange portion 5.
Since the opening 6 is provided so as to face the a, by using this as an insertion hole, it is easy to attach the wire spoke 4, and the opening 6 also prevents the tire 7 and the rim 2 from slipping. This makes it possible to improve the fit of the tire.

することができる。 Further, the locking portions of such wire spokes 5 are connected to relatively rigid flange portions 5, 5 at both ends of the rim.
By providing the rim with a hollow structure and making the flange portion 5 hollow, the entire rim can be made thinner and lighter. Furthermore, by providing the opening 6, the weight can be further reduced. Therefore, these reduce the rotational inertia of the wheels and reduce the gyro effect, thereby making it possible to stabilize the maneuverability.

回転慣性を小さくすることができる。 Further, as in the embodiment, the wire spokes 4 are divided into a central spoke 4c and an outer spoke 4s, and the ends of the two spokes 4c and 4s are connected to each other by a connecting device at an intermediate position between the hub 1 and the rim 2. 8, the weight of the rim can be reduced compared to conventional wheels in which nipples are provided on the rim, and the rotational inertia can be reduced.
Further, as shown in FIG. 7, if the diameter of the outer spokes 4s is made smaller than that of the central spokes 4c, the weight at a distance farther from the axis of rotation is reduced, and the rotational inertia can be further reduced.

上するようにすることができる。 As described above, the wire spoke wheel of the present invention has a closed wall structure in the rim region sandwiched between both bead portions of the tire, a raised portion in the portion that contacts the inner side of the bead portion, and a hollow flange portion. The tubeless tire has a structure in which a locking hole for locking the end of the wire spoke is provided at the bottom, and an opening is provided on the inner wall surface where the bead comes in contact with the locking hole to face the locking hole. Even if the rim is attached, the ridge prevents the bead from sliding toward the inside of the rim, so air leakage can be prevented. In addition, the wire spoke locking holes are provided in the hollow flange, making it possible to lock the wire spokes without causing air leaks.Additionally, the openings are provided on the inner wall of the flange to face the locking holes. By providing this hole, it can be used as a hole for insertion when assembling wire spokes, and it can also prevent slippage between the tire and the rim in the circumferential direction and improve the ease of mounting.
