プの原因になつていた。 Conventionally, as shown in FIGS. 1 and 2, this type of wheel 1 includes a rim 2 and a boss 3, which are made of an integral member formed by coupled rolls, and a plate-shaped spoke disk 5 having a plurality of arms 5a. Furthermore, the center portion of the disk 5 is formed into a dish shape by press working, and a cup-shaped hub 6 is attached to the dish-shaped portion 5b.
and further fit the hub 6 with the boss 3 and disc 5.
The brake shoe 7 was welded to the dish-shaped portion 5b of the brake shoe 7, and the brake shoe 7 was placed therein. By the way, since the rim 2 of the wheel 1 is formed by a combination of rolls, distortion occurs during the forming process.If the rim 2 is made of wire spokes, it can be absorbed during assembly, but if the rim 2 is made of wire spokes, it can be absorbed during assembly. If this happens, the distortion cannot be absorbed, and even after the wheel 1 is completed, the distortion remains, deteriorating the accuracy of the wheel 1. Furthermore, as shown in FIG. 3, a disc wheel 1' has been devised in which two rim pieces 2'a, 2'b formed by press working are connected by bolts 9. Since the disc 5' and the hub 6' are integrally formed by one rim piece 2'a, the pressing process becomes very complicated, and the other rim piece 2'b is punched out in the center. The punched disc-shaped steel plate becomes scrap, resulting in extremely large waste of material and causing an increase in costs.

とを目的とするものである。 Therefore, in the present invention, a wheel is formed by pressing two disc-shaped steel plates, a rim piece and a disc are integrally formed from one of these steel plates, and the center portion of the other steel plate is punched out. The other rim piece is formed from a circular ring-shaped steel plate, and the cup-shaped hub is formed from a punched small-diameter disc-shaped steel plate. It is an object of the present invention to provide a method for manufacturing a disc wheel for a two-wheeled vehicle, which can be manufactured at low cost by press working without wasting material.

る。 The disc wheel 11 for a two-wheeled vehicle is a rim 1
2, a boss 13, a disk 15, and a hub 16, and the entire wheel 11, except for the boss 13, is formed by pressing two disc-shaped steel plates 17 and 19. That is, the outer diameter portion of one steel plate 17 is connected to the flange 1 of one rim piece 12'.
2'a and a bead 12'b are formed, and furthermore, a disk 15 is formed in the central portion thereof, which includes a joining plan view 15a, a fitting bulge 15b, and a dish-shaped portion 15c. The center portion of the other steel plate 19 is punched out, and the steel plate 19 is divided into an annular steel plate 19a and a small-diameter disc-shaped steel plate 19b. The annular steel plate 19a forms the flange 12''a and bead 12''b of the other rim piece 12'', and further forms the joint plane portion 15'a.
The small-diameter disc-shaped steel plate 19b is the dish-shaped portion 1 of the disc 15.
A cup-shaped hub 16 is formed into which the bottom and part of the side surfaces fit into the hub 5c. Furthermore, both joint plane parts 15
A hole 21 for a fixing device is formed in the bead 12''b, and a hole 22 for a valve is formed in the bead 12''b, and a boss is formed in the dish-shaped portion 15c and the center of the bottom of the hub 16 by press working. In addition to forming holes 23 and 25 for the disk 13, fixing flanges 26 and 27 are respectively formed around the holes 23 and 25 for the fitting bulge 1 of the disk 15.
A suitable hole 29 is punched in 5b. The integral parts of the rim piece 12'a and the disc 15 manufactured as described above are first welded to the boss 13 by the collar 26, and then the hub 16 is fitted into the dish-shaped part 15c of the disc 15, and the bottom surface is shaped like a dish. The part 15c is spot welded, and the collar 27 is welded to the boss 13. Also,
Along with installing the tire, the rim piece 12'' is attached to the steel plate 19b.
Fit the fitting bulge 15b of the disk 15 into the punched hole 30 and position it, then insert the bolt 31 into the hole 21 of both the joint plane parts 15a, 15'a, and tighten the nut 32. According to rim 12
, and the disk wheel 11 is assembled.

安価に製造することができる。 As explained above, according to the present invention, the rim 1
2 is formed by relatively simple pressing of two steel plates 17 and 19, so a highly precise rim can be constructed, and one of these steel plates 17 is formed by rim piece 1.
Since the disk 15 is integrally formed with 2' and the fitting bulge 15b and dish-shaped part 15c are formed, the strength is increased and the fitting position with the other rim piece 12'' and the hub 16 is accurate. It is possible to obtain a highly reliable wheel 11 with excellent precision and strength as a whole.Furthermore, all of the parts except the boss 13 are formed by pressing the steel plates 17 and 19, and the pressing process is performed by deep drawing. Since only a relatively simple press process is required, the process can be performed accurately and the processing cost can be significantly reduced.Furthermore, the other steel plate 19 can be formed into an annular steel plate 1 by punching.
9a and a small-diameter disc-shaped steel plate 19b, and the annular steel plate 19a constitutes the rim piece 12'', and the small-diameter disc-shaped steel plate 19b constitutes the hub 16, so that material collection can be carried out effectively. ,
It is also possible to reduce material costs. As a result of the above effects, the wheel 11 with excellent precision and strength can be manufactured at low cost.
