Problems solved by technology
However, the combined rim of this structure can only be connected because the sleeve needs to be locked with the wheel frame. At the same time, the sleeve and the hub are also fitted with sleeves, so there is bound to be a problem of fit clearance and tolerance at the connection. It affects the service life of the product and the aesthetics of the product, and the assembly of the traditional rim needs to punch a lot of holes on the rim, which destroys the strength of the rim

Embodiment Construction
[0022] Cooperate Figure 1 to Figure 6 As shown, the present invention discloses a combined rim structure, which includes a wheel frame 1 , a hub 2 and several spoke rods 3 connecting the wheel frame 1 and the hub 2 .
[0023] Key of the present invention is:
[0024] The inner wall of the wheel frame 1 is provided with a feed port 11 at a position corresponding to the spoke rods 3 , and the hub 2 and several spoke rods 3 are integrally formed on the wheel frame 1 .
[0025] That is, after the hub 2 and several spoke rods 3 are formed on the wheel frame 1, the materials for forming the hub and spoke rods 3 can be filled in the wheel frame 1 at the same time, so that the wheel frame 1 and the spoke rods 3 are more firmly combined, and the spokes The rod 3 and the hub 2 are integrally formed, so the entire rim structure not only has a uniform appearance and is convenient in manufacturing process, but also has better structural strength of the rim and longer product life.

The invention discloses a combined type rim structure and a process for manufacturing the same. The combined type rim structure comprises a wheel frame, a hub and a plurality of spoke rods; the wheel frame is connected with the hub by the spoke rods; and feed inlets are arranged on the inner wall of the wheel frame and correspond to the spoke rods, and the hub and the spoke rods are integrally formed on the wheel frame. The combined type rim structure and the process have the advantages that by a technology for arranging the feed inlets on the wheel frame which is formed in advance, and then secondarily forming the spoke rods and the hub on the wheel frame, the process for manufacturing the combined type rim structure can be effectively simplified, materials for forming the hub and the spoke rods can be simultaneously filled in the wheel frame, the wheel frame can be combined firmly with the spoke rods, the spoke rods and the hub are of an integrally formed structure, accordingly, the rim structure not only is unified in appearance, but also is high in strength and long in service life, and the process for manufacturing the combined type rim structure is convenient.
Description
technical field [0001] The invention relates to a rim applied to motorcycles, bicycles, wheelchairs and other related products, in particular to a combined rim structure and its manufacturing process. Background technique [0002] A common wheel rim is composed of many spokes connected between a hub shell and the wheel frame. Such thin rod-shaped spokes are not strong enough and are easily damaged by external forces, and the number of spokes is large. , resulting in a heavier overall weight. Therefore, there is an integrated rim, which is formed by forming the hub, the wheel frame and the sleeve connecting the hub and the wheel frame in one mold by using polymer composite materials, but this kind of wheel requires the hub, the wheel frame and the The bushings must be of the same material, so use with rims is somewhat limited. [0003] Therefore, the inventor of this case designed a utility model patent with the notification number CN201511757U, which discloses a lightweigh...
