【発明の詳細な説明】 ［産業上の利用分野］ 本発明は、車両用エンジンに搭載される樹脂製サージタ
ンクの製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for manufacturing a resin surge tank mounted on a vehicle engine.

されている。[Prior Art] Many vehicle engines have a surge tank interposed in their intake system to ensure stable intake. In the past, surge tanks were commonly made of metal, such as welded aluminum die-cast assemblies, but since there is a natural limit to the weight reduction of metal products, recently, surge tanks have been replaced with metal ones. It has been proposed to use a surge tank molded from a strong and lightweight polymeric resin material such as nylon.

ところが、単にサージタンクを樹脂化したのみでは、そ

い虞れが生じてくる。特に過給機付エンジンにこのよう

が望ましい。However, if the surge tank is simply made of resin, there is a risk that its strength will be insufficient and that it will not be able to fully exhibit the necessary functional durability. In particular, when such a surge tank is employed in a supercharged engine, there is a high risk that the surge tank, which is a pressure vessel, will burst due to internal pressure during use. Therefore, when the surge tank is made of resin, it is desirable to mold it with a resin containing a reinforcing material such as glass fiber.

る。Furthermore, when molding a resin surge tank, it would be advantageous if a one-piece product made by blow molding could be used, as manufacturing and assembly would be simplified. However, when attempting to make a rectangular shaped container such as a surge tank by blow molding, uneven thickness inevitably occurs due to uneven molding conditions, making it impossible to obtain a product with uniform thickness. Therefore, application of blow molded products to this type of internal pressure container is unsuitable.

各サージタンク片の接合部同士を摩擦させて熱溶着する
ことが提案されている。Therefore, when planning to replace the surge tank with a resin surge tank, it is currently necessary to use a separate assembly of the surge tank. In other words, the surge tank pieces that have been molded into a plurality of pieces must be injection molded using a mold, and then they must be joined and integrated. At that time, if a solvent or adhesive can be used, it can be relatively easily joined, but from the viewpoint of reliability of joint strength, etc., the joined parts of each segmented surge tank piece are rubbed together and thermally welded. It is proposed that.

詰まりを引起こす原因となる。[Problems to be Solved by the Invention] However, when the joint parts of the surge tank pieces are frictionally welded together in this way, the reinforcing material for reinforcing the resin is exposed on the melted joint surface, and this reinforcing material is Friction between the joints often causes them to be crushed and dispersed, and end up adhering to the inside of the surge tank. If this reinforcing material is transported from the surge tank to the engine intake system during engine operation, it can cause various problems. For example, when glass fiber or the like is used as a reinforcing material, crushed glass fibers adhering to the inside of the surge tank can crowd the slow ports of the vaporizer, negative pressure passages for various controls, etc. These can cause clogging.

本発明は、樹脂製サージタンクに関するこのような不具

る。[Means for Solving the Problems] In order to achieve the above object, the present invention provides a method for joining surge tank pieces that have been molded into segments containing a reinforcing material and thermally welding the joints by friction. The present invention is characterized in that a resin member that can be melted earlier than the surge tank piece and does not contain the reinforcing material is provided on the inner edge of the portion.

I will do it. Therefore, even if the reinforcing material exposed on the joint surfaces is crushed due to friction between the joint surfaces, this resin material melts first and closes the inner edge of the joint, so that the inside of the surge tank can also be seen from the joint of the surge tank pieces. This prevents the reinforcing material from penetrating and adhering to the inner wall surface, etc.

According to the welding method, a resin member 13.14 having a melting point lower than that of the lid piece 2 and the main piece 3 is attached to the inner edge of the joint part 4.5 of each of the lid piece 2 and the main piece 3 at the re-joined part 4.5. Since it is sandwiched between the lid piece 2 and the main piece 4,
Although some particles protrude between the resin members 13 and 13, 14, these resin members 13 and 14 prevent glass fibers and the like contained in the lid piece 2 and the main piece 3, which will later be melted, into the surge tank 1. Prevent intrusion. Therefore, problems such as glass fibers and the like being carried from the intake port 8 to the vaporizer and the like, resulting in clogging of the negative pressure passages, etc., can be effectively avoided.

3a and 14a are the welding surfaces 2a of the lid piece 2 and the main piece 3,
It protrudes from 3a by a slight distance m. In this way, when the lid piece 2 and the main piece 3 are vibration welded, the resin members 13 and 14 will always melt first, so the surge tank can be welded from the welding surfaces 2a and 3a of the lid piece 2 and the main piece 3. 1. Leakage of glass fibers etc. into the interior can be reliably prevented.

Open portions 211 and 212 are formed, and these open portions 211 and 212 are filled with a resin member 213 made of nylon 6 or the like that does not contain glass fiber.
214 is fitted. In this case, the welding surfaces 2 of the resin members 213 and 214 are slightly protruded from the welding surfaces 203a and 204a of the surge tough pieces 203 and '204.
A certain space j is provided on each side of 13a and 214a.

In this way, when the surge tank pieces 202, 203 are vibration welded together, the welding surfaces 213a, 214a of the resin members 213, 214 melt first, sealing the inner edges of the welding surfaces 202a, 203a, and welding Space j1 contains glass fibers that are about to enter the surge tank from surfaces 202a and 203a.
This makes it possible to reliably prevent glass fibers and the like from entering the surge tank.

Therefore, when the surge tank pieces are joined and integrated, the resin member can effectively prevent the reinforcing material from entering the surge tank. the result,
To provide a method for manufacturing a highly reliable surge tank that avoids problems such as reinforcing material contained in surge tank pieces being carried into various negative pressure passages of an intake system, combustion chamber, etc., without reducing strength. be able to.
