Description

Technical Field

[0001] The utility model relates to the field of wheel hub manufacturing, in particular to a high-air-tightness steel wire motorcycle wheel hub. Background Art

[0002] The motorcycle wheel is an important part of the motorcycle, used to support the weight of the entire vehicle and transmit power. Motorcycles are usually equipped with two wheels, front and rear wheels, both of which are made of spokes or alloy wheels. The tire is the outer part of the wheel, which provides friction and grip, and is usually made of rubber.

[0003] Motorcycle wheels are similar to bicycle wheels, but their spokes are different from car tires. Motorcycle spokes are composed of a center disk and steel wires (spokes), and the spokes and rim further form a complete hub. During the connection process, one end of the motorcycle steel wire is fixed by the center disk, and the other end passes through the rim to the rim surface, and the steel wire head on the rim surface is locked to complete the fixation of the spoke. Bolts or a flattening machine are usually used to flatten the steel wire head for locking. No matter which one is used, there is a gap between the rim and the steel wire left when the steel wire passes through. When the wheel hub is put into use, that is, assembled with the tire and inflated internally, the gas in the tire will leak out of the gap under the air pressure and the pressure during driving, causing the motorcycle tire to slowly leak. In the long run, insufficient tire pressure will cause safety hazards and frequent under-pressure during driving. Summary of the invention

[0004] The technical problem to be solved by the utility model is that there are gaps between the rims of motorcycles on the market and the steel wires, which are left when the steel wires penetrate. When the wheel hub is put into use, that is, assembled with the tire and inflated internally, the gas in the tire will leak out from the gaps under the air pressure and the pressure during driving, causing the motorcycle tire to leak slowly. In the long run, insufficient tire pressure will cause safety hazards and frequent under-inflation during driving.

[0005] In order to solve the above problems, the utility model provides the following technical solutions:

[0006] A high-air-tightness steel wire motorcycle wheel hub comprises a rim and a spoke, wherein a thorn is arranged on the inner wall of the rim, and a rim stop wire hole is arranged on the thorn, and the spoke comprises a center plate and a steel wire, one end of the steel wire is fixedly connected to the center plate, and the other end passes through the rim stop wire hole, a connecting bolt is arranged on one side of the rim stop wire hole, and the connecting bolt is threadedly connected to the steel wire.

[0007] Furthermore, one end of the steel wire is a fixed end, and the other end is a connecting end, the fixed end is fixedly connected to the middle disk, the connecting end passes through the steel wire hole and is threadedly connected to the connecting bolt, and the connecting end is provided with an external thread.

[0008] Furthermore, the steel wire is L-shaped, and the connecting end is bent toward one side of the vitex.

[0009] Furthermore, the bramble is in a circular shape and is integral with the rim, and a plurality of rim stop wire holes are provided along the bramble.

[0010] The beneficial effects of the utility model are:

[0011] The steel wire is connected to the rim through the bramble, so that the steel wire does not need to penetrate the rim when connected to the rim, so that no through holes or gaps will be formed. When the tire is placed and inflated, the rim surface seal will not leak and the air tightness will be improved. During driving, there will be no underpressure or safety hazard caused by the steel wire connection. The tire is easy to install and disassemble. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0020] See also Figure 1-4 The high airtightness steel wire motorcycle wheel hub shown in the figure comprises a rim 1 and a spoke 2. A thorn 1a is arranged on the inner wall of the rim 1. A rim stopper steel wire hole 3 is arranged on the thorn 1a. The spoke 2 comprises a middle plate 2a and a steel wire 2b. One end of the steel wire 2b is fixedly connected to the middle plate 2a, and the other end passes through the rim stopper steel wire hole 3. A connecting bolt 4 is arranged on one side of the rim stopper steel wire hole 3. The connecting bolt 4 is threadedly connected to the steel wire 2b. The difference from the traditional motorcycle wheel hub is that the steel wire of the traditional motorcycle wheel hub, i.e., the spoke, passes through the surface of the rim 1 and is fixed on the surface. Bolt fixing or flattening fixing, but no matter which method is used, there will be gaps on the surface of the rim 1 due to the penetration of the steel wire. When the tire is installed on the surface of the rim 1 and inflated, under the action of road driving pressure and tire pressure, the gas in the tire may slowly overflow and cause leakage. In the present application, the rim 1 adopts the inner wall to set up a thorn 1a to connect with the spoke 2, and the rim stop steel wire hole 3 is obliquely penetrated through the rim stop steel wire hole 3 and then connected and fixed by the connecting bolt 4, and no gaps are left by penetrating the rim 1, completely avoiding the defect of insufficient air tightness.

[0021] See also Figure 4 One end of the steel wire 2b is a fixed end 2ba, and the other end is a connecting end 2bb. The fixed end 2ba is fixedly connected to the middle disk 2a. The connecting end 2bb passes through the steel wire hole 3 and is threadedly connected to the connecting bolt 4. The connecting end 2bb is provided with an external thread. When connected, the fixed end 2ba of the steel wire 2b is fixedly connected to the middle disk 2a. Because of its inclination, the connecting end 2bb can be easily inserted into the bramble 1a and pass through the rim stop steel wire hole 3, and then locked and limited by the connecting bolt 4.

[0022] The steel wire 2b is L-shaped, and the connecting end 2bb is bent toward the side of the vitex 1a.

[0023] The bramble 1 a is in a circular shape and is integrated with the rim 1 . A plurality of rim stop wire holes 3 are provided along the bramble 1 .

[0024] See also Figure 5 In some embodiments, such as motorcycles with smaller wheel sizes, or bicycles and electric bicycles, Figure 5The hub structure of the middle single-spoke 1a can match tires with small radius sizes and reduce structural material loss without affecting the stability of the hub.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0026] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other methods that can be understood by those skilled in the art.
