Detailed Description
The following description of the present invention will be made in detail with reference to the accompanying drawings 1 to 7.
the rim is 8 inches; the diameter d of the inner circle 2 of the rim is 184.4mm +/-3 mm;
the length x of the welding between the outer side 51 of the single connecting piece and the wall surface of the inner circle 2 of the rim is 10-60 mm, and when the length x is 10mm, the welding strength of the rim and the connecting piece can be met; a length x of less than 10mm easily causes breakage of the spoke and increases the difficulty of welding. A length x higher than 60 significantly increases the welding cost.
The quantity n of connector 5 is 3 ~ 9, and the quantity of connector and spoke is unanimous, and the minimum quantity requirement of spoke is three, and the design of 5 spokes is selected for use to this embodiment.
The sum mx of the welding lengths of all the connectors 5 is 30-300 mm. When the number of spokes is large, a coupling member having a small length x can be selected, and accordingly, when the number of spokes is small, a coupling member having a large length x must be selected to ensure coupling strength. In the embodiment, 5 connecting pieces are selected, the length of each connecting piece is 1mm, and the sum mx of the welding lengths is 50 mm.
As can be seen from the data in the table, the strength of the coupling piece and the sum of the welding lengths are directly related, and the number of the coupling pieces and the change of the welding length of a single coupling piece have no influence basically under the condition that the sum of the welding lengths is the same.
When the ratio of the sum mx of the welding lengths to the length pi d of the inner circumference of the 8-inch hub is lower than 5.2%, the total welding strength of the connecting piece is lower than 20KN, potential safety hazards can exist, and when the length of a single connecting piece is lower than 10mm, the welding difficulty can be improved; therefore, in comprehensive comparison, the sum mx of the welding lengths of all the coupling members 5 is not less than 30mm, which is a preferable choice. When the ratio of the sum mx of the welding lengths to the length of the inner circumference pi d is higher than 51.8%, the strength of 200KN is far beyond the safety standards, and the cost is also increased significantly. Therefore, it is preferable that the ratio of the sum mx of the welding lengths to the inner circumference length pi d is 5.2% to 51.8%.
Preferably, the joint of the connecting piece 5 and the rim is provided with a welding seam 6, and the width w of the seam is 0.3 mm-15 mm. In the embodiment, argon arc welding is adopted in the connecting part and the rim, the welding wire is 1mm, and the welding gun needs to stretch into a welding gap, so that the reserved welding gap is relatively large, and the width w is 10 mm.
Preferably, the coupling member 5 has a thickness h of 0.5mm to 8 mm. This example is 4 mm.
Preferably, the spoke has a thickness H of 5mm to 30 mm. This embodiment is 25 mm.
Preferably, the length of the portion of the coupling member 5 that is embedded in the corresponding spoke is L, which is 3mm to 50 mm. This embodiment is 30 mm.
Preferably, the cross section of the connecting piece 5 is L-shaped, and the welding seam is arranged at the bending position of the connecting piece; the welding wire is along the department of bending welding connector and rim inner wall, and the area of welding of the department of bending is great, and welding effect is better.
Example 2, as shown in fig. 4, this example is substantially the same as example 1, except that the gap is a laser welded gap having a width w of 3mm or less. In this embodiment, the welding method is laser welding, and the width w of the laser welding seam is 1 mm.
Preferably, the outer side of the coupling piece 5 is welded to the inner wall of the rim to a depth y,
the effective welding area S between the single coupling piece 5 and the rim 3 is x y,
the effective welding area S of the single connecting piece 5 is more than or equal to 10mm2. In this embodiment, the effective welding area S is 10mm2. The depth y of the laser welding is controlled by the laser welder, and the greater the power of the laser welder, the greater the welding depth.
Example 3 this example is substantially the same as example 1 except that the coupling 5 has an "|" shape in cross section and both sides of the outer end of the coupling are simultaneously welded to the inner circumferential surface of the rim, as shown in fig. 5 to 6. The two sides of the outer end of the connecting part are welded with the rim by argon arc welding.
Example 4, this example is substantially the same as example 3 except that two of the outer ends of the coupling member are different, as shown in fig. 7The welding depth of the side and the rim is Dy1 and Dy2, the effective welding area S of a single connecting piece is (Dy1+ Dy2) x, and S is more than or equal to 10mm2. Dy1+ Dy2 is less than or equal to the thickness h of the connecting piece, and in the embodiment, both sides of the outer end of the connecting piece are welded with the rim into a whole through laser welding.
Example 5, this example is substantially the same as example 1 except that the rim is 10 inches and the diameter d of the inner circle 2 of the rim is 235.2mm ± 3 mm;
when the ratio of the sum mx of the welding lengths to the length pi d of the inner circumference of the 10-inch hub is lower than 4.1%, the total welding strength of the connecting piece is lower than 20KN, potential safety hazards can exist, and when the length of a single connecting piece is lower than 10mm, the welding difficulty can be improved; therefore, in comprehensive comparison, the sum mx of the welding lengths of all the coupling members 5 is not less than 30mm, which is a preferable choice. When the ratio of the sum mx of the welding lengths to the length of the inner circumference pi d is higher than 40.6%, the strength of 200KN is far beyond the safety standards, and the cost is also increased significantly. Therefore, the ratio of the sum mx of the welding lengths to the inner circumference length π d is 4.1% to 40.6%.
It should be noted that when the sum mx of the welding lengths of the coupling pieces 5 is 45-150 mm; the ratio of the sum mx of the lengths of the welds to the length of the inner circumference pi d is between 6.1% and 20.3%, and the applicant has found that a combination of strength and cost is preferred when the sum of the lengths of the welds of the coupling is 45mm (i.e. when 3 hubs of a coupling having a width of 15mm are used).
Example 6, this example is substantially the same as example 1 except that the rim is 12 inches and the diameter d of the inner circle 2 of the rim is 286.0mm + -3 mm;
the ratio mx/pi d of the sum mx of the welding lengths to the length pi d of the inner circumference can reach a minimum value of 3.3%, and under the condition that a product meets the standard, the lower the value is, the smaller the welding length is, the less time is required for welding, the specification of the connecting piece is relatively smaller, and the cost is the lowest; the width of a single coupling piece is 10mm, and the number of the coupling pieces is 3.
When the ratio of the sum mx of the welding lengths to the length of the inner circumference pi d is higher than 33.4%, the strength of 200KN is far beyond the safety standards, and the cost is also increased significantly. Therefore, the ratio of the sum mx of the welding lengths to the inner circumference length π d is 3.3% to 33.4%.
