[0051] <Example 1>

[0052] Figure 1 is a three-dimensional diagram of the disc brake hub and the disc brake disc in this embodiment, Figure 2 It is a cross-sectional view of the disc brake hub and disc brake rotor.

[0053] like Figure 1 and Figure 2 As shown, this embodiment provides a disc brake hub 100, one side of which is mounted with a disc brake disc 200. The structure of the disc brake hub 100 is designed based on the structure and installation requirements of the disc brake disc 200, so the structure of the disc brake disc 200 will be briefly described below.

[0054] The disc brake disc 200 is a full-disc disc brake disc, also called a reverse disc brake disc, and its outer diameter is close to the diameter of the disc brake hub 100. The disc brake disc 200 is generally in the shape of a circular ring plate, with a circular inner edge and a gear-shaped outer edge. The disc brake disc 200 is provided with a plurality of friction holes 201 and a plurality of fixing holes 202. The plurality of friction holes 201 are circular through holes with relatively small apertures, and are evenly distributed on the edge of the inner ring of the disc brake disc 200; the plurality of fixing holes 202 are countersunk holes, and are evenly distributed circumferentially on the edge of the outer ring of the disc brake disc 200. In this embodiment, there are a total of six fixing holes 202. According to actual needs, the number of fixing holes 202 can also be 3 to 5.

[0055] The structure of the disc brake hub 100 of this embodiment will be described in detail below in conjunction with the structure of the disc brake disc 200 described above.

[0056] The disc brake hub 100 (a hub on which a disc brake can be mounted) includes a disc brake rim 10A and spokes 30 .

[0057] Figure 3 is a three-dimensional diagram of the disc brake rim in this embodiment, Figure 4 It is a structural exploded view of the disc brake rim in this embodiment.

[0058] like Figure 3 and Figure 4 As shown, the disc brake rim 10A includes a rim body 10 (rim) and a plurality of disc brake disc mounting seats 20 (mounting seats). The plurality of disc brake disc mounting seats 20 are respectively arranged on the same axial side of the rim body 10 (i.e., one side of the rim 10), and are evenly distributed along the circumference of the wheel flange 13 of the rim body 10, and are used to mount the above-mentioned disc brake disc 200. In this embodiment, corresponding to the number of fixing holes on the disc brake disc 200, there are also six disc brake disc mounting seats 20 in total.

[0059] The rim body 10 includes a groove bottom 11, a bead seat 12 and a wheel flange 13. Along the circumference of the rim body 10, the cross-section of the groove bottom 11 is roughly in the shape of a trapezoidal groove, which is convenient for disassembling and installing the tire.

The bead seat 12 is used to support the tire in the radial direction. Two wheel flanges 13 are respectively formed on both sides of the two bead seats 12, and a bend is formed between the wheel flange 13 and the corresponding bead seat 12. The two wheel flanges 13 are respectively used to clamp on both sides of the tire rim to support the tire and maintain the axial direction of the tire. The specific structure of the rim body is the prior art.

[0060] Figure 5 is a three-dimensional diagram of the disc brake mounting seat in this embodiment, Figure 6 1 is a stereoscopic view of the disc brake mounting seat at different angles in this embodiment. Figure 7 It is a cross-sectional view of the disc brake mounting seat in this embodiment.

[0061] like Figures 5 to 7 As shown, the disc brake mounting seat 20 includes a seat body 21 (screw seat) and a fixing member 22 (connecting member), a part of the fixing member 22 is combined in the seat body 21, that is, the seat body 21 is covered on the fixing member 22. The seat body 21 and the fixing member 22 are metal parts of different materials, and the fixing member 22 and the rim 10 are metal parts of the same material. The seat body 21 is covered on the fixing member 22, so that the two metals of different materials are tightly combined.

[0062] The seat body 21 is an integrally formed part, and is generally in the shape of a column with missing corners. Along its length direction, it can be divided into a support positioning portion 211 and a fixing member coupling portion 212. The seat body 21 also has a mounting hole 213 for fixing the disc brake disc 200.

[0063] The support and positioning portion 211 is generally in the shape of a rectangular block, and the outer contour of the cross section along the length direction of the seat body 21 is a rectangular shape with rounded corners. The outer end of the support and positioning portion 211 has a positioning end surface 2111 for supporting and positioning the edge of the disc brake disc 200. The positioning end surface 2111 is a plane that is perpendicular to the length direction of the seat body 21.

[0064] The support and positioning portion 211 is generally in the shape of a rectangular block, and the outer contour of the cross section along the length direction of the seat body 21 is a rectangular shape with rounded corners. The outer end of the support and positioning portion 211 has a positioning end surface 2111 for supporting and positioning the edge of the disc brake disc 200. The positioning end surface 2111 is a plane that is perpendicular to the length direction of the seat body 21.

The groove width of the receiving groove 2122 is greater than the diameter of the tail of the threaded rod.

[0067] Along the axial direction of the mounting hole 213, the mounting hole 213 includes a first hole portion 2131, a second hole portion 2132 and a third hole portion 2133 which are connected in sequence. Among them, the first hole portion 2131 is a tapered hole with a very shallow depth, and the end with a relatively larger aperture is the mounting opening 2131. The second hole portion 2132 is a circular hole, and its aperture is substantially consistent with the aperture of the end with a smaller aperture of the first hole portion 2131, and its depth is greater than the depth of the first hole portion 2132. The third hole portion 2133 is a threaded circular hole, and its inner surface has threads. The depth of the third hole portion 2133 is much greater than that of the second hole portion 2132, and one end of the third hole portion 2133 is a through opening 2132.

[0068] The fastening rod 300 matching the mounting hole is a screw with a nut, through which the disc brake disc 200 is tightened on the disc brake disc mounting seat 20 . The fastening rod 300 includes a coaxially arranged fastener head (nut portion) 310 and a screw portion 320 .

[0069] The fastener head 310 includes a cap portion 311, a transition portion 312, and a tightening hole 313. The cap portion 311 is roughly in the shape of a circular plate with chamfers. The transition portion 312 extends from the middle of a side surface of the cap portion 311 that does not have chamfers. The transition portion 312 is cylindrical and has a diameter smaller than the diameter of the cap portion 311. The tightening hole 313 is provided on the cap portion 311 and part of the transition portion 312. The tightening hole 313 is a hexagonal hole. In this embodiment, the outer diameter of the cap portion 311 is slightly smaller than the upper end diameter of the fixing hole 202 on the disc brake disc 200. The outer diameter of the transition portion 312 is slightly smaller than the lower end diameter of the fixing hole 202 on the disc brake disc 200 and is also slightly smaller than the diameter of the second hole portion 2132 of the mounting hole 213. The overall length of the transition portion 312 is equal to or slightly smaller than the sum of the lengths of the hole portion at the lower end of the fixing hole 202, the first hole portion 2131 and the second hole portion 2132.

[0070] The screw portion 320 is a round rod with threads on the outer surface, and the threads match the threads of the third hole portion 2133 of the mounting hole 2133. In this embodiment, the overall length of the screw portion 320 is greater than the length of the third hole portion 2133.

[0073] The coupling part 221 is used to couple with the seat body 21. The coupling part 221 is located in the middle of the entire fixing member 22. The coupling part 221 is roughly in the shape of a bent square frame. When viewed from the side, the coupling part 221 is also in the shape of a chamfered L. The coupling part 221 can be regarded as being composed of a first sheet-like part 2211 in a U shape (a transverse section in the bending direction), a second sheet-like part 2212 in a U shape (a vertical section in the bending direction), and two roughly T-shaped connecting parts 2213 (transition sections) connected before the two sheet-like parts, wherein the two ends of the connecting part 2213 are respectively connected to the corresponding ends (U-shaped ends) of the first sheet-like part 2211 and the second sheet-like part 2212, and the length direction of the connecting part 2213 is inclined relative to the surface direction of the first sheet-like part 2211 and the surface direction of the second sheet-like part 2212, and the surface direction of the first sheet-like part 2211 and the surface direction of the second sheet-like part 2212 are roughly perpendicular. In addition, the second sheet portion 2212 has a relatively small curvature as a whole, which is substantially consistent with the curvature of the inner side of the bead seat 12. Since the size of the fixing member 22 is relatively small relative to the overall size of the rim body 10, the curvature is very small, and the second sheet portion 2212 can also be a straight sheet.

[0074] The middle of the joint 221 has a large through-hole 2214, the shape of which corresponds to the overall shape of the joint 221, and the four corners of the middle hole 2214 are all rounded. There are a plurality of joint notches 2215 on both sides of the bending direction of the joint 221. In this embodiment, the joint notches 2215 are rectangular notches with rounded corners, and there are four joint notches 2215 in total. There are two joint notches 2215 on each side of the joint 221, and the notches on both sides are symmetrically distributed, and the opening direction of the joint notches 2215 is perpendicular to the bending direction of the fixing member 22. The width of the joint notch 2215 is greater than its depth, and the corners of the joint notch 2215 are all rounded. The rounded setting prevents the corresponding position inside the seat body 21 from forming a sharp angle shape that is easily damaged when subjected to force, thereby making the joint strength between the seat body 21 and the fixing member 22 higher.

[0075] The two fixing portions 222 are respectively formed at the two ends of the bending direction of the connecting portion 221 (i.e., the two ends of the L shape). The fixing portion 222 is in the shape of a rectangular sheet, extending from one end of the connecting portion 221, and the length direction of the fixing portion 222 is perpendicular to the bending direction of the connecting portion 221. The length of the fixing portion 222 is the same as the width of the one end of the connecting portion 221, and the surface direction of the fixing portion 222 is consistent with the surface direction of the one end of the connecting portion 221. In addition, the outer end of the fixing portion 222 is rounded.

[0076] One of the fixing portions 222 has a relatively narrow width, and the fixing portion 222 serves as the wheel rim fixing portion 222a; the other fixing portion 222 has a relatively wide width, and the fixing portion 222 serves as the groove bottom fixing portion 222b. In addition, the outer end of the wheel rim fixing portion 222a has a relatively small curvature, which is substantially consistent with the curvature of the circumference of the wheel rim 13. Similarly, the curvature is very small, and the outer end of the wheel rim fixing portion 222a can also be straight.

[0077] The hole portion of the middle hole 2214 close to the wheel rim fixing portion 222a is used as a hollow portion 2214a (hollow and open filling groove), and the hole portion of the middle hole 2214 close to the groove bottom fixing portion 222b is used as a combination hole 2214b. The boundary line between the hollow portion 2214a and the combination hole 2214b is roughly located in the middle of the middle hole 2214 in the bending direction of the fixing member 22, that is, the filling groove is distributed on the transverse section and / or the transition section.

[0078] In an alternative solution, the fixing member 22 may also be in an overall L-shape with rounded corners, that is, a curved sheet-like member.

[0079] In this embodiment, the fixing member 22 is used for welding with the rim body. Due to the provision of the fixing member 22, the seat body 21 can be made of a material different from that of the rim body.

[0080] When arranged on the rim 10, a hollow cavity is formed between the middle of the fixing member 22 and the rim 10, and the seat body 21 is filled into the hollow cavity. The hollow cavity ensures that there is sufficient bonding space between the fixing member 22 and the seat body 21, thereby ensuring bonding strength.

[0081] like Figure 5As shown, the seat body 21 completely wraps the connecting portion 221 of the fixing member 22, and the seat body 21 has a portion formed integrally in the connecting hole 2214b and multiple connecting notches 2215 of the connecting portion 221, that is, in addition to the mounting hole 213, the seat body 21 also has multiple holes and grooves matching the outer shape of the connecting portion 221, and these holes and grooves are not connected to the mounting hole 213. Therefore, the seat body 21 as a whole forms a relatively complex wrapping and clasping structure for the connecting portion 221, so that the connection between the seat body 21 and the connecting portion 221 is very firm. Multiple fixing portions 222 are located outside the seat body 21, wherein the rim fixing portion 222a is located outside the side of the fixing member connecting portion 212 of the seat body 21 close to the supporting positioning portion 211, and is located on the side of the fixing member connecting portion 212 having the matching notch 2121, and the surface direction of the rim fixing portion 222a is perpendicular to the length direction of the seat body 21. The groove bottom fixing portion 222b is located outside the outer end of the fixing member coupling portion 212 of the seat body 21, and the surface direction of the groove bottom fixing portion 222b is perpendicular to the thickness direction of the seat body 21. The plurality of fixing portions 222 are used to be fixed at corresponding predetermined positions on the rim body 10. In this embodiment, the fixing portion 222 is used to be welded to the rim body 10.

[0082] In addition, in the length direction of the seat body 21, the mounting hole 213 passes through the hollow portion 2214a of the fixing member 22. That is, by providing the hollow portion 2214a, the structure of the fixing member 22 avoids the position (punching position) of the mounting hole 213 on the seat body 21, and the structure of the fixing member 22 forms a structure that surrounds the lower part of the mounting hole 213 on three sides.

[0083] Fig. 9 yes Figure 2 Enlarged view of the part within the middle circle A.

[0084] like Fig. 9 As shown, when set on the rim 10, the rim fixing portion 222a is used to be welded on the rim 13 of the rim 10 as the above-mentioned predetermined position, and the groove bottom fixing portion 222b is used to be welded on one side of the groove bottom 11 of the rim 10 as the above-mentioned predetermined position.

[0085] Specifically, the surface direction of the rim fixing portion 222a and a side surface facing the mating notch 2121 are in contact with the outer end portion of the rim 13 in the axial direction of the rim 10, and welding is performed between the outer end surface of the rim fixing portion 222a and the outer end portion of the rim 13 to form a strip-shaped rim welding portion 41 (welding point one).

[0086] The surface direction of the groove bottom fixing portion 222b is perpendicular to the radial direction of the rim 10, so the outer end face of the groove bottom fixing portion 222b is perpendicular to the axial direction of the rim 10, and the inner side surface of the groove bottom 11 is inclined relative to the outer end face of the groove bottom fixing portion 222b, so one side of the outer end face of the groove bottom fixing portion 222b is in contact with an inner side surface of the groove bottom 11, and a gap is formed between the other side of the outer end face of the groove bottom fixing portion 222b and the inner side surface of the groove bottom 11, and the outer end face of the groove bottom fixing portion 222b and the inner side surface of the groove bottom 11 are welded by using the gap to form a strip-shaped groove bottom welding portion 42 (welding point two).

[0087] That is, the disc brake rim 10A further includes a rim welding portion 41 and a groove bottom welding portion 42 formed of welding material. In the present embodiment, the rim welding portion 41 and the groove bottom welding portion 42 are formed by laser welding.

[0088] The length direction of the seat body 21 is consistent with the axial direction of the rim 10, and the thickness direction of the seat body 21 is consistent with the radial direction of the rim 10. The positioning end face 2111 of the seat body 21 is perpendicular to the axial direction of the rim 10. In the axial direction of the rim 10, the support and positioning portion 211 of the seat body 21 is located outside the rim 10, so the positioning end face 2111 is also located outside the rim 10, so it can be used to install a disc brake disc 200 with an outer diameter close to the diameter of the rim 10. In the radial direction of the rim 10, the seat body 21 does not exceed the outermost end of the rim 10, so it will not affect the installation of the tire.

[0089] The lower end of the cap portion 311 of the fastener 300 is accommodated in the upper portion of the fixing hole 202 (counterbore) of the disc brake disc 200, the transition portion 312 is accommodated in the lower portion of the fixing hole 202 and the first hole portion 2131 and the second hole portion 2132 of the mounting hole 213, the screw portion 320 passes through the third hole portion 2133, and the outer end portion of the screw portion 320 is accommodated in the accommodating groove 2122 of the seat body 21.

[0090] The spoke 30 is fixed to the inner ring of the rim body 10 and is used to support the rim body 10. The specific structure of the spoke is prior art.

[0091] As described above, in this embodiment, six disc brake disc mounting seats 20 are arranged on the rim body 10 of the disc brake hub 100, and the positioning end faces 2111 of the six disc brake disc mounting seats 20 are substantially on the same plane, and the plane is perpendicular to the axial direction of the disc brake hub 100. Therefore, after the disc brake disc 200 is mounted on the six disc brake disc mounting seats 20 through the six fastening rods 300, the disc brake disc 200 is located outside one side of the disc brake hub 100 in the axial direction, and the surface direction of the disc brake disc 200 is also perpendicular to the axial direction of the disc brake hub 100. When the corresponding brake clamps the inner ring of the disc brake disc 200 to brake, the disc brake disc 200 is subjected to friction and applies a force opposite to its rotation direction to the rim body 10 through the fastening rod 300 and the disc brake disc mounting seat 20. Since the surface direction of the disc brake disc 200 is also perpendicular to the axial direction of the disc brake hub 100, the direction of the corresponding stress on the fastening rod 300 can be kept basically perpendicular to the axial direction of the fastening rod 300.

[0092] Functions and Effects of Embodiment 1

[0093] According to the disc brake disc mounting seat, disc brake rim and disc brake hub provided in the present embodiment, the disc brake wheel includes a rim body and a plurality of disc brake disc mounting seats arranged on the rim body, and can thus be used to install disc brake discs. Each disc brake disc mounting seat includes a seat body and one or more fixing members, which are combined with the seat body and fixed at a predetermined position on the rim body. Therefore, the seat body can be made of a material different from that of the rim, and the seat body of different materials can be firmly combined with the rim body through the fixing members. In this way, the restriction on the seat body material is very small, and the seat body material can be selected according to the production and processing needs or the required specific material properties, so that the processing of the seat body is more convenient or has specific material properties, thereby improving the production efficiency of the disc brake hub or producing a disc brake hub with a wider range of applications.

[0094] Furthermore, the fixing piece has a hollow portion, and the mounting hole on the seat body passes through the hollow portion on the fixing piece, so when punching the seat body, the fixing piece will not be touched at all, and the structural strength of the disc brake disc mounting seat will not be affected by the punching. In addition, when installing the fastening rod, the hollow portion can also accommodate the lower part of the fastening rod without hindering the installation of the fastening rod, so the axial length of the mounting hole can be set longer, and a longer fastening rod can also be used, thereby further improving the firmness of the disc brake disc installation.

[0095] Furthermore, the fixing piece is a single bent sheet-like piece, and its hollow portion and the combining hole are two parts of the same central hole, so that the fixing piece is easier to process and manufacture.

[0096] Furthermore, the seat body is formed on the fixing part by die casting, and the fixing part also has a coupling hole and a plurality of coupling notches, so the seat body can form a relatively complex wrapping structure for the fixing part, so that the coupling strength between the two is higher and can withstand higher stress. In addition, the corners of the coupling hole and the coupling notch are rounded, which can avoid the formation of sharp and easily damaged corners inside the seat body, making the seat body more reliable.

[0097] Furthermore, one end of the seat body has a matching notch corresponding to the inner side of the rim, so that the supporting positioning portion on the upper part of the seat body can be closer to the radial outer ring of the rim through the matching notch, so that multiple disc brake disc mounting seats can be used to install disc brake discs with larger outer diameters.

[0098] Furthermore, the seat body also has a receiving groove connected to the matching notch, and the mounting hole on the seat body is a through hole with one end connected to the receiving groove. Therefore, there is no need to strictly control the punching depth when punching the mounting hole, and the processing of the mounting hole is more convenient and more efficient.

[0099] Furthermore, according to the structure of the disc brake mount in the embodiment, for each disc brake mount, only two straight or nearly straight welding operations need to be performed at the rim and the groove bottom of the wheel rim, which makes the processing very convenient and efficient while ensuring the structural strength.

[0100] <Example 2>

[0101] The present embodiment provides a disc brake disc mounting seat, a disc brake rim and a disc brake hub. In the present embodiment, the same symbols are given to the same components as those in the first embodiment and the corresponding descriptions are omitted.

[0102] Compared with the first embodiment, the difference is that in the disc brake rim of this embodiment, the structure of the disc brake disc mounting seat is different.

[0103] Fig.10 is a three-dimensional diagram of the disc brake mounting seat in this embodiment, Fig.11 2 is a three-dimensional diagram of the fixing member in this embodiment.

[0104] like Fig.10 and Fig.11 As shown, in the disc brake disc mounting seat 20 of the disc brake rim 10A of this embodiment, the fixing member 22 is a split fixing member, and accordingly, the structure of the seat body 21 combined with the fixing member 22 is also different from that of the first embodiment.

[0105] Specifically, the fixing member 22 of this embodiment includes a first sheet member 223 and a second sheet member 224 which are separated from each other by processing of a first sheet material and a second sheet material. The plane directions of the first sheet member 223 and the second sheet member 224 are substantially perpendicular to each other, and the first sheet member 223 and the first sheet member 224 are arranged to form an L shape.

[0106] The first sheet member 223 is in a U-shaped sheet shape and includes a first combining portion 2231 and a first fixing portion 2232 .

[0107] The first joint part 2231 is also in the shape of a U-shaped sheet, and has a first clearance notch 22311 and two first joint notches 22312. The first clearance notch 22311 is located at one end of the length direction of the first sheet 223 and in the middle of the width direction. It is relatively large in size, and its depth and width are slightly smaller than the length and width of the first joint part 2231, respectively. Its opening direction is consistent with the length direction of the first sheet 223. The two first joint notches 22312 are relatively small in size and are symmetrically arranged on both sides of the width direction of the first joint part 2231. Their opening direction is consistent with the width direction of the first sheet 223. The corners of the first clearance notch 22311 and the first joint notch 22312 are both rounded. The two ends of the first joint part 2231 are roughly in the shape of a rectangular sheet with rounded corners.

[0108] The first coupling portion 2231 is wrapped inside the fixing member coupling portion 212 of the base body 21 and is located near the support positioning portion 211, and the surface direction of the first coupling portion 2231 is perpendicular to the length direction of the base body 21. The mounting hole 213 on the base body 21 passes through the first clearance notch 22311 on the first coupling portion 2231, and the depth of the first clearance notch 22311 is greater than the aperture of the mounting hole 213.

[0109] The first fixing portion 2232 extends from one end of the U-shaped bottom of the first combining portion 2231, and the length direction of the first fixing portion 2232 is consistent with the U-shaped opening direction of the first combining portion 2231, and the length of the first fixing portion 2232 is the same as the width of the one end of the first combining portion 2231. The first fixing portion 2232 is used as a wheel rim fixing portion 222a, and its structure is the same as that of the wheel rim fixing portion 222a in the first embodiment.

[0110] The second sheet member 224 is also in a U-shaped sheet shape, and includes a second combining portion 2241 and a second fixing portion 2242 .

[0111] The second combining portion 2241 is also in the shape of a U-shaped sheet, and has a middle combining notch 22411 and two second combining notches 22412. The middle combining notch 22411 is used as the hollowing portion described in the first embodiment. The middle combining notch 22411 is located at one end in the length direction and the middle in the width direction of the second sheet 224. It is relatively large in size, and its depth and width are slightly smaller than the length and width of the second combining portion 2241, respectively. Its opening direction is consistent with the length direction of the second sheet 224. The two second combining notches 22412 are relatively small in size and are symmetrically arranged on both sides in the width direction of the second combining portion 2241. Their opening direction is consistent with the width direction of the second sheet 224. The corners of the middle combining notch 22411 and the second combining notch 22412 are both rounded. The two ends of the second combining portion 2241 are roughly in the shape of a rectangular sheet with rounded corners.

[0112] The second coupling portion 2241 is wrapped inside the fixing member coupling portion 212 of the base body 21 and is located beside the matching notch 2121 . The surface direction of the second coupling portion 2241 is perpendicular to the thickness direction of the base body 21 .

[0113] The second fixing portion 2242 extends from one end of the U-shaped bottom of the second combining portion 2241, and the length direction of the second fixing portion 2242 is consistent with the U-shaped opening direction of the second combining portion 2241, and the length of the second fixing portion 2242 is the same as the width of the one end of the second combining portion 2241. The second fixing portion 2242 is used as a groove bottom fixing portion 222b, and its structure is the same as that of the groove bottom fixing portion 222b in the first embodiment, that is, its width is greater than the width of the first fixing portion 2232.

[0114] That is, the overall structures of the first sheet member 223 and the second sheet member 224 are very similar, but the functions of the first clearance notch 22311 and the middle joining notch 22411 thereon are different. In addition, the structures of the first sheet member 223 and the second sheet member 224 are also very similar to the structures of the two ends of the fixing member 22 in the bending direction in the first embodiment.

[0115] In addition, the second sheet-like member 224 has a relatively small curvature as a whole, which is substantially consistent with the curvature of the inner side of the bead seat 12. Similarly, the second sheet-like member 224 may not have the curvature and may be in the form of a straight sheet.

[0116] like Fig.11As shown, the seat body 21 completely wraps the first joint part 2231 and the second joint part 2232 of the fixing member, so the structure of the holes and grooves corresponding to the shapes of the two joint parts inside the seat body 21 is different from that in the first embodiment. In the first embodiment, corresponding to the shapes of the two sides of the bending direction of the joint part 221, two long through holes are formed inside the seat body 21, while according to the shape of the fixing member 22 of this embodiment, there will be no particularly long through holes inside the seat body 21.

[0117] The mounting hole 213 on the base 21 passes through the first clearance notch 22311 on the first sheet 223 of the fixing member 22, and the first sheet 223 surrounds the lower part of the mounting hole 213 on three sides. The second sheet 224 is located at the side of the mounting hole 213 and does not contact or interfere with the mounting hole 213.

[0118] In this embodiment, other structures are the same as those in the first embodiment, and thus will not be described again.

[0119] Functions and Effects of Embodiment 2

[0120] According to the disc brake disc mounting seat, disc brake rim and disc brake hub provided in this embodiment, on the basis of the functions and effects of the first embodiment, since the overall L-shaped fixing member is composed of two separated sheet members, there is no need to perform overall bending processing on the fixing member, but only needs to process the two sheets into two relatively straight sheet members respectively, which makes the processing more convenient and quick, and also makes the production efficiency of the disc brake rim higher.

[0121] Furthermore, the overall shapes of the first sheet member and the second sheet member are very similar, and the first clearance notch and the middle combining notch with basically the same shape are used to achieve different functions. Through such a clever design, the difficulty of processing can be further reduced and the production efficiency can be improved while meeting the functional requirements.

[0122] Furthermore, since the first sheet-like member and the second sheet-like member are two independent components, the distance between the two can be adjusted as needed, so that the fixing member can be used in conjunction with rims of different sizes and / or seat bodies of different sizes, that is, the same fixing member can be used when manufacturing a variety of different models of disc brake rims and disc brake hubs. Therefore, the fixing member has a wider range of applications, is more convenient to operate during production changes, and has higher production efficiency.

[0123] <Example 3>

[0124] The present embodiment provides a disc brake disc mounting seat, a disc brake rim and a disc brake hub. In the present embodiment, the same symbols are given to the same components as those in the first embodiment and the corresponding descriptions are omitted.

[0125] Compared with the first embodiment, the difference lies in that in the disc brake rim of this embodiment, the structure of the disc brake disc mounting seat is different. The metal sheet therein is a metal sheet with a certain thickness, and both sides of the long side or the wide side of the metal sheet are attached to the surface of the rim; it is that both sides of the wide side of the metal sheet are attached to the surface of the rim and welded to form the third welding joint.

[0126] Fig.12 Figure 4 is a three-dimensional view of the disc brake disc mounting seat and the rim in this embodiment, Fig.13 Figure 5 is a three-dimensional view of the fixing member and the rim in this embodiment.

[0127] As Fig.12 and 13 shown, specifically, the fixing member 22 of this embodiment is integrally formed by bending a sheet material, has an axisymmetric structure, and is generally in a U shape as a whole, and the opening of the U shape faces the center of the rim 10. The fixing member 22 includes two engaging portions 221 and a fixing portion 222.

[0128] The fixing portion 222 is located in the middle of the bending direction of the entire fixing member 22. The fixing portion 222 is a bent sheet, and its cross-section along the axial direction of the rim 10 is in a U shape, and one side of the middle of the fixing portion 222 has an opening groove 2217 (relieving groove) for serving as the above-mentioned hollow portion. The opening groove 2217 is a rectangular notch with rounded corners, and its opening direction is perpendicular to the bending direction of the fixing member 22. Its depth is about 1 / 2 of the width of the middle of the fixing portion 222, and its width is greater than the aperture of the mounting hole 213 of the seat body 21. In addition, the middle of the fixing portion 222 can be in a flat sheet shape or have a curvature consistent with the inner side of the bead seat 12.

[0129] Along the bending direction of the fixing portion 222, a bending portion 225 is formed between the middle of the fixing portion 222 and its two ends. The bending portion 225 is bent approximately 90 degrees, and the outer surface of the bending portion 225 includes two planes and a quarter cylindrical surface connecting between the two planes.

[0130] The two engaging portions 221 (insertion portions) extend from both ends of the fixing portion 222 in the bending direction respectively. The engaging portion 221 is in a rectangular sheet shape, and its surface direction is consistent with the surface direction of the corresponding end of the fixing portion 222. The length direction of the engaging portion 221 is the width direction of the corresponding end of the fixing portion 222, and the length of the engaging portion 221 is basically the same as the width of the end of the fixing portion 222. The engaging portion 221 has a middle hole 2214 (hollow groove) for serving as an engaging hole. The middle hole 2214 is a square through hole with rounded corners. In addition, the corners of the outer ends of the engaging portion 221 are also rounded.

[0131] The two coupling parts 221 are parallel to each other, and the surface direction of the coupling parts 221 is perpendicular to the width direction of the base body 21. The lower part of the mounting hole 213 on the base body 21 is located in the opening groove 2217 and the space beside the opening groove 2217 (i.e., the space surrounded by the two coupling parts 221 and the fixing part 222). The lower end of the fastening rod 300 is also accommodated in the opening groove 2217 and the above space.

[0132] The fixing portion 222 of the fixing member 22 contacts the inner side of the bead seat 12 of the rim 10, and a straight line welding is performed between the quarter cylindrical surface of the two bent portions 225 (i.e., the two sides of the long side of the connecting member) and the inner side surface of the bead seat 12 to form two bead seat welding portions 43. That is, the disc brake hub 100 of this embodiment also only includes two bead seat welding portions 43 (welding location three).

[0133] In addition, the fixing member 22 in this embodiment can also be transformed into a split structure similar to that of the second embodiment, that is, the fixing member 22 of this embodiment can be divided into two sheet-like members roughly along its symmetry axis, which can also achieve effects similar to those of the fixing member 22 of this embodiment and the fixing member 22 of the second embodiment.

[0134] Likewise, according to the shape of the fixing member 22 of this embodiment, the structure of the corresponding hole and groove in the seat body 21 is different from that in the first embodiment.

[0135] In this embodiment, other structures are the same as those in the first embodiment, and thus will not be described again.

[0136] Functions and Effects of Embodiment 3

[0137] According to the disc brake disc mounting seat, disc brake rim and disc brake hub provided in this embodiment, on the basis of the functions and effects of the first embodiment, since the above-mentioned fixing member structure is adopted and welding is performed between the two symmetrical sides of the fixing member and the inner side of the bead seat of the rim, only two straight line weldings are required for each disc brake disc mounting seat, and the welding operation is more convenient. Moreover, the two bead seat welding parts formed by welding are located at the inner ring of the rim, which are less susceptible to wear than the welding parts formed on the wheel flange, etc., thereby improving the overall reliability of the disc brake rim.

[0138] <Example 3>

[0139] The present embodiment provides a disc brake disc mounting seat, a disc brake rim and a disc brake hub. In the present embodiment, the same symbols are given to the same components as those in the first embodiment and the corresponding descriptions are omitted.

[0140] Compared with the first embodiment, the difference lies in that in the disc brake rim of this variant, the structure of the disc brake disc mounting seat is different. The structure of the metal sheet is as follows: The metal sheet includes two vertical side walls and a horizontal side wall connecting the two vertical side walls. A hollow groove is provided on the vertical side wall or the horizontal side wall. The two vertical side walls and one horizontal side wall enclose a horizontally placed U-shaped body, and the opening of the U-shaped body faces the side wall of the rim; the screw connection seat covers the horizontal side wall; the two vertical side walls abut against the outer surface of the bead seat of the rim; the parts of the two vertical side walls abutting against the rim are exposed from the screw connection seat, and the ends of the two vertical side walls are welded to the outer side wall of the bead seat of the rim, forming the welding joint four.

[0141] Fig.14 It is a three-dimensional view of the fixing member and the rim in this embodiment.

[0142] As Fig.14 shown, the fixing member 22 (connecting member) of this embodiment is integrally formed by a bent sheet (metal sheet), which has an axisymmetric structure. Its cross-section along the axial direction of the rim 10 is in a U shape, and the opening of the U shape faces the bead seat 12 of the rim 10. The fixing member 22 includes a combining portion 221 and two fixing portions 222.

[0143] The combining portion 221 is located in the middle of the entire fixing member 22 in the bending direction. It is in the shape of a bent sheet, and its cross-section along the axial direction of the rim 10 is also in a U shape. Moreover, the width of the middle part of the combining portion 221 in the bending direction is smaller than the widths of both ends. The middle part of the combining portion 221 is in a flat sheet shape (horizontal side wall) and has a middle hole 2214 in the shape of a rectangle, which is used as a combining hole. Both ends of the combining portion 221 respectively have end combining holes 2216 in the shape of a rectangle.

[0144] The two fixing portions 222 respectively extend from both ends of the combining portion 221 in the bending direction. The fixing portions 222 are in the shape of rectangular sheets. The surface direction of the fixing portions 222 is the same as the surface direction of the corresponding end of the combining portion 221, and the length of the fixing portions 222 is the same as the width of the corresponding end of the combining portion 221. Both of the two fixing portions 222 are used as bead seat fixing portions 222c. The straight ends of the fixing portions 222 corresponding to the combining portion 221 form vertical side walls.

[0145] The outer end faces of the two bead seat fixing portions 222c are respectively in contact with the inner sides of the bead seats 12 of the rim 10. Welding is performed between the outer side surface of the outer end of each bead seat fixing portion 222c (i.e., the side surface opposite to the other bead seat fixing portion 222c) and the inner side surface of the bead seat 12, forming two strip-shaped bead seat welding portions 43 (welding joint four). That is, compared with the first embodiment, the disc brake rim 10A of this embodiment does not have a rim welding portion 41 and a bottom welding portion 42, but has two bead seat welding portions 43.

[0146] The surface direction of the middle portion of the coupling portion 221 is perpendicular to the radial direction of the rim 10 , so that the thickness direction of the seat body 21 is consistent with the radial direction of the rim 10 .

[0147] The hollow portion is surrounded by the combination portion 221 and the two fixing portions 222. The lower portion of the mounting hole 213 on the base 21 is located in the space surrounded by the combination portion 221 and the two fixing portions 222, and the lower portion of the fastening rod 300 can also penetrate into the space.

[0148] In addition, the fixing portion 222 of the present embodiment is in the shape of a rectangular sheet, but other shapes may be used, such as an L-shape, in which the sheet portion of the outer end portion of the fixing portion 222 contacts the inner side surface of the bead seat 12; or a T-shape, in which the bottom of the T-shape is integrated with the coupling portion 221, and the outer end surface of the top of the T-shape contacts the inner side surface of the bead seat 12. Similarly, welding between the outer end portion of the L-shaped or T-shaped fixing portion 222 and the inner side surface of the bead seat 12 can also achieve the same effect.

[0149] Likewise, according to the shape of the fixing member 22 of this embodiment, the structure of the corresponding hole and groove inside the seat body 21 is different from that in the first embodiment.

[0150] In this embodiment, other structures are the same as those in the first embodiment, and thus will not be described again.

[0151] Functions and Effects of Embodiment 4

[0152] According to the disc brake disc mounting seat, disc brake rim and disc brake hub provided in this embodiment, on the basis of the functions and effects of the first embodiment, since the above-mentioned fixing member structure is adopted and welding is performed between the two symmetrical sides of the fixing member and the inner side of the bead seat of the rim, only two straight line weldings are required for each disc brake disc mounting seat, and the welding operation is more convenient. Moreover, the two bead seat welding parts formed by welding are located at the inner ring of the rim, which are less susceptible to wear than the welding parts formed on the wheel flange, etc., thereby improving the overall reliability of the disc brake rim.

The disc brake hub 100 of this embodiment only includes the groove bottom welding portion 42 (welding point five).

[0171] In addition, the distance between the coupling portion 221 and the inner side of the bead seat 12 is greater than the aperture of the mounting hole 213 of the seat body 21, and the lower part of the mounting hole 213 is located in the space between the coupling portion 221 and the bead seat 12, and the lower end of the screw portion 320 of the fastening rod 300 can also be accommodated in the space.
