Description

本発明は、分岐ホースとレゾネータが吸気ダクトに取付けられてなる吸気部品の取付構造に関する。   The present invention relates to an intake part mounting structure in which a branch hose and a resonator are mounted on an intake duct.

分岐ホースが吸気ダクトに組付く分岐ホースの取付構造としては、従来より種々のものが知られている（例えば、特許文献１参照）。特許文献１に紹介されている分岐ホースの取付構造は、吸気ダクトと分岐ホース（ＰＣＶホース）との取付構造に関する。この種の分岐ホースの取付構造においては、吸気ダクトと分岐ホースとの間に、硬質のユニオン部材を介在させるのが一般的である。図４に示すように吸気ダクト１０１には上記分岐ホース１０２とは別にレゾネータ１０４が取付けられる場合がある。こうした構成では、吸気ダクト１０１は第１クランプ１０５でユニオン１０３と締結し、第２クランプ１０６でレゾネータ１０４と締結する。また、ユニオン１０３と分岐ホース１０２は第３クランプ１０７で締結している。この為、吸気ダクト１０１とユニオン１０３及びレゾネータ１０４との接続部ではクランプが２つ必要で部品点数が多く、組付け工程が増え、製造コストが高いと言う問題があった。
特開２００２−１５５７２０号公報 Conventionally, various attachment structures for a branch hose in which the branch hose is assembled to the intake duct are known (see, for example, Patent Document 1). The branch hose mounting structure introduced in Patent Document 1 relates to a mounting structure of an intake duct and a branch hose (PCV hose). In this type of branch hose mounting structure, a hard union member is generally interposed between the intake duct and the branch hose. As shown in FIG. 4, a resonator 104 may be attached to the intake duct 101 in addition to the branch hose 102. In such a configuration, the intake duct 101 is fastened to the union 103 by the first clamp 105 and fastened to the resonator 104 by the second clamp 106. The union 103 and the branch hose 102 are fastened by a third clamp 107. For this reason, there is a problem in that the connection portion between the intake duct 101, the union 103, and the resonator 104 requires two clamps, increases the number of parts, increases the assembly process, and increases the manufacturing cost.

The resonator 4 is also made of resin and includes a resonator main body 40 having a predetermined space inside and a second attachment portion 41 connected to the second branch portion 12 of the intake duct 1. The hose connection part 3 and the resonator 4 are integrated with each other via the connecting part 5. Further, the central axis A of the first mounting portion 31 of the hose connecting portion 3 and the central axis B of the second mounting portion 41 of the resonator 4 are coplanar and intersect each other (C-shaped), and the first mounting The first opening 31a of the portion 31 and the second opening 41a of the second attachment portion are opened in different directions.

ホース接続部３、レゾネータ４、連結部５はブロー成形で一体成形する方法や、射出成形でホース接続部３、連結部５とレゾネータ本体４０の半分割体を一体形成し、残りのレゾネータ本体４０の半分割体を成形し、各々の半分割体を溶着する等して適宜製造することができる。   The hose connecting portion 3, the resonator 4 and the connecting portion 5 are integrally formed by blow molding, or the hose connecting portion 3, the connecting portion 5 and the resonator main body 40 are integrally formed by injection molding, and the remaining resonator main body 40 is integrally formed.
