[0048] The following are specific embodiments of the present invention, and the technical solution of the present invention is further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0049] Embodiment 1:

[0050] like Figure 1-Figure 4 A wheel rim capable of mounting a disc brake is shown, which comprises a bottom groove 11, a bead seat 13 and a wheel flange 12. A plurality of mounting seats 2 are arranged on the circumference of the wheel rim 1, and the mounting seats 2 are used for mounting the disc brake.

[0051] The mounting seat 2 includes a connecting seat 3 and a connecting member 4;

[0052] The connecting piece 4 is made of iron material. Since the material of the rim 1 is usually also iron material, the connecting piece 4 can be easily welded to the rim 1 .

[0053] The connecting member 4 is tubular, and the preferred shape of the connecting member 4 is a square tube.

[0054] The interior of the connecting member 4 is formed as a through hole 41 , and a connecting groove 5 is formed on the side wall of the connecting member 4 , and the connecting groove 5 is connected to the through hole 41 .

[0055] The connecting seat 3 is made of aluminum.

[0056] After pouring the liquid aluminum into the mold, the upper end of the connector 4 can be inserted into the mold, and the aluminum can be formed into a connector seat 3 through the connector 4 cooperating with the mold, and the connector seat 3 is fixed to the upper end of the connector 4 to form a mounting seat 2.

[0057] When the connection seat 3 is connected to the connection member 4, the lower end of the connection seat 3 is filled in the through hole 41, and the portion of the lower end of the connection seat 3 filled in the through hole 41 is formed into the fixing portion 31. This molding method is very simple and easy to operate, and can improve the efficiency of producing the mounting seat 2.

[0058] The preferred material of the connector 4 is an iron pipe, which can be quickly and accurately formed into a desired shape by laser cutting, so as to facilitate shaping of the connector 3 in cooperation with a mold.

[0059] Since the iron pipe production and manufacturing technology is simple and the price is low, whether purchasing iron pipes from the market or producing them by yourself can greatly reduce production costs, and can reduce the links in the production and processing process, thereby achieving the goal of increasing costs and efficiency.

[0060] The connecting member 4 is preferably in the shape of a square tube or a round tube.

[0061] like Figure 1-Figure 4 As shown, one side of the lower end of the connecting member 4 is an abutting end 42, and the abutting end 42 abuts against the peripheral side of the rim 12;

[0062] An extension section 43 is formed on the other side of the lower end of the connecting member 4 and extends downward. The bottom end of the extension section 43 abuts against the side wall of the bottom groove 11 .

[0063] When the connecting member 4 is placed on the peripheral side of the rim 1 , the lower end of the connecting member 4 is made to match the shape of the inner wall of the rim 1 , which is convenient for subsequent processing.

[0064] A welding edge 44 is formed on a side of the extension section 43 facing the rim 1 . The welding edge 44 is close to the inner wall of the rim 1 , specifically, the inner wall close to the wheel flange 12 .

[0065] Since the position of the wheel rim 12 is relatively flat, subsequent welding work is convenient.

[0066] The welding position is shown as weld 7 in the figure.

[0067] At the same time, the bottom of the abutting end 42 and the extension section 43 are also close to the inner wall of the rim 1, which is easy to weld. More welding positions can improve the connection strength between the connecting member 4 and the rim 1, ensure the stability of the mounting seat 2, and extend the service life of the disc brake.

[0068] like Figure 1-Figure 4 As shown, a protrusion 32 is formed on the connection seat 3, and the protrusion 32 will be filled in the connection groove 5, so that the connection member 4 and the connection seat 3 cannot be separated.

[0069] Since the aluminum connection seat 3 will not naturally adhere to the inner wall of the connection piece 4 made of iron material after molding, it is necessary to mold a specific shape on the fixing portion 31 to prevent the connection seat 3 from detaching from the connection piece 4 from above.

[0070] Specific as 2- Figure 4 As shown, in this embodiment, the connecting groove 5 includes:

[0071] A flow channel portion 51, which passes through the connecting member 4 upward;

[0072] A locking groove 52 formed on a side surface of the flow channel portion 51;

[0073] The profile of the protrusion 32 matches the flow channel 51 , and a locking protrusion 33 is protrudingly formed on the side surface of the protrusion 32 so that the locking protrusion 33 can be placed in the locking groove 52 .

[0074] When the locking protrusion 33 and the locking groove 52 cooperate with each other, the connection seat 3 and the connection member 4 can be restricted from being separated.

[0075] like Figure 1-Figure 5 As shown, the upper end of the connecting seat 3 is formed as a threaded portion 34, and a threaded hole 35 is formed on the threaded portion 34. The threaded hole 35 is used for threading the disc brake pad.

[0076] Furthermore, an avoidance groove 36 is formed on the fixing portion 31 , and the lower end of the threaded hole 35 passes through the top of the avoidance groove 36 .

[0077] Embodiment 2:

[0078] Specific as Figure 6 As shown, this embodiment is basically the same as the first embodiment, except that:

[0079] The upper part of the connecting groove 5 does not penetrate the connecting member 4 , and the protrusion 32 is directly placed in the connecting groove 5 , thereby preventing the connecting member 4 and the connecting seat 3 from being separated.

[0080] Embodiment three:

[0081] Specific as Figure 7 As shown, this embodiment is basically the same as the first embodiment, except that:

[0082] A symmetrically arranged connecting groove 5 is formed on the side wall of the connecting member 4 , and a fixing pin 6 is passed through the connecting groove 5 so that the fixing pin 6 can be partially passed through the inside of the through hole 41 .

[0083] The end of the fixing pin 6 can be welded to the connecting groove 5 to fix the fixing pin 6 on the connecting member 4 .

[0084] After the connection seat 3 is formed, the connection seat 3 can be covered on the outside of the fixing pin 6 located in the through hole 41 to prevent the connection seat 3 and the connecting member 4 from being separated.

[0085] Furthermore, threads are formed on the outside of the fixing pin 6 to improve the connection strength between the fixing pin 6 and the two connecting seats 3 .

[0086] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
