[Detailed explanation of the idea]

0001

[Industrial application field]

This idea was applied to curved radiators equipped with fans installed in motorcycles, etc. For details, see the stay for attaching the fan to the radiator body and its This invention relates to improvements to mounting brackets.

0002

[Conventional technology]

On motorcycles equipped with water-cooled engines, the handle post (also known as the head pipe) It is common to place the radiator directly behind the radiator. However, in the same position When placing a radiator, make it larger to increase its cooling capacity. With a flat structure, there is a risk of interference with the front wheels. So, put the radiator in front of The so-called curved structure has a concave curved structure toward the front wheels to prevent interference with the front wheels. The curved radiator is as described in Japanese Patent Laid-Open No. 63-184582. It is publicly known.

0003 By the way, when installing an electric fan for forced cooling on a curved radiator, Usually, one end of the stay is fixed to the mounting plate on the back of the fan by welding, etc., and the lamp is Brackets are installed on the core plates that make up both the upper and lower sides of the radiator body. The other end of the stay is fixed to the bracket with fasteners such as bolts and nuts.

0004 As shown in FIGS. 7 and 8, conventionally, the bracket 52 of the core plate 57 is provided with a mounting hole 52b for mounting one end of the stay 58 with a stopper 59. The mounting surface 52a is shaped parallel to the curved surface of the radiator body 51 at the mounting position. It had been done. On the other hand, the fan 55 is mounted on the back surface of the convexly curved radiator main body 51. , parallel to the tangent S of the curved surface at the center position of the radiator body 51. It is arranged so that Therefore, the strip fixed to the mounting plate 56 side of the fan 55 Portion c of the tape 58 is parallel to the mounting plate 56 and on the mounting surface 52a side of the bracket 52. The portion a of the stay 58 that is fixed to is also formed parallel to the mounting surface 52a. Ta. Therefore, the stay 58 has a portion c of the stay 58 on the fan mounting plate 56 side. As shown in FIG. 9, the stay 5 is perpendicular to the stay part a on the bracket mounting surface 52a side. It was necessary to twist and form part b of No. 8 so as to follow the curved surface of the part b.

[0005]

[Problem that the idea aims to solve]

The conventional stay described above has the following disadvantages.

[0006] The developed shape of the stay is complicated, and the yield is reduced because it is not possible to use a fixed length strip. It's bad.

[0007] To punch out the stays, a special cutting die called a blank die is required.

[0008] General-purpose drawing (press) molds cannot be used to form each bent part of the stay. Therefore, it is necessary to make a special mold.

[0009] Due to the above-mentioned reasons, the manufacturing process of the stay is complicated and the cost is high.

0010 As shown in FIG. 7, the portion c of the stay 58 on the bracket 52 side is connected to the radiator main body 5. 1, and the portion c of the stay 58 is located close to the curved surface of the back side of the radiator. Since it covers a part of the body 51, the flow of cooling air passing through the radiator may be obstructed. There is that.

[0011] This idea eliminates the above-mentioned disadvantages, and in particular simplifies the manufacturing process of the stay. This reduces manufacturing costs, and the stay blocks the flow of cooling air in the radiator. The purpose is to provide a curved radiator with a fan that does not cause any harm.

0012

[Means to solve the problem]

In order to achieve the above object, the curved radiator of the present invention has: a) a convex curve; In a curved radiator with a fan in the center of the back of the radiator body, b) Attach the core plate of the radiator body at the center position on the back side of the radiator body. A plurality of brackets having mounting surfaces parallel or substantially parallel to the tangent line are integrally formed, and c ) Attach the other end of the stay, one end of which is fixed to the mounting plate on the back of the fan, to the corresponding front It is fixed to the mounting surface of the bracket via a stopper. Note that the bracket is It may be formed integrally with the core plate from the beginning, or the bracket and core plate may be formed integrally with the core plate. After forming the plate separately, the bracket is fixed to the core plate by welding etc. It may be formed physically.

[0013]

[Effect]

According to the curved radiator of the present invention having the above configuration, the back side of the radiator body When the fan is installed on the bracket, the stay part on the bracket (mounting surface) side of each stay The part is parallel to the stay part on the fan mounting plate side, and there is no twisting. Therefore As a result, the unfolded shape of the stay is simple, and it can be made from a fixed length strip using a general-purpose punching die. Efficiently punch through the stay plate material. Also, a general-purpose drawing die can be used. Ru. This reduces the manufacturing cost of the stay. In addition, if you install the bracket from the beginning When formed integrally with the core plate, the shape of the core plate is slightly more complex than before. Although it may be complicated, the core plate originally has a complicated shape, so it is necessary to use a special punching die. Since the bracket is formed using a drawing die or a drawing die, it is possible to There are almost no disadvantages.

[0014] Also, the stay part on the bracket side is parallel to the stay part on the fan mounting plate side. By doing so, an appropriate gap is created between the back of the radiator and the radiator. The flow of cooling air passing between the corrugated fins is not obstructed and the air flow rate is sufficient. The cooling capacity is maintained for 30 minutes and the cooling capacity does not decrease.
