- the silencer casing 8 can be divided into two parts without interfering with 16.
- the silencer element 7 is provided on the outer periphery of the silencer rib 11 so as to be sandwiched between the panels 10a and 10b, and has a substantially cylindrical shape.
- the silencer element 7 can be divided into two at a substantially horizontal position.
- Such a silencer element 7 is formed by arranging a plurality of substantially plate-like elements (sound absorbing materials) 7 a at substantially equal intervals in the circumferential direction of the outer periphery of the motor generator housing 6.
- the substantially plate-like element 7a has a substantially V-shaped cross section as shown in FIGS.
- As the material of the element 7a for example, glass wool is used.
- FIG. 11 shows a partially enlarged view when the silencer element 7 constituted by such an element 7a is divided into two in the vertical direction.
- each element 7a is divided between the elements 7a at positions corresponding to the joint surfaces of the upper silencer casing 8a and the lower silencer casing 8b. That is, as shown in FIG. 9B, each element 7a is formed between the elements 7a at positions corresponding to the joint surfaces, and is divided in the outside air flow path 18 through which air passes, and the element 7a itself is divided in the vertical direction.
- the motor generator housing 6 (see FIGS. 3 and 4) is arranged in the circumferential direction so as not to occur. Since the element 7a is not divided by arranging the element 7a as shown in FIG. 11, the silencer element 7 can be divided into two without impairing the silencing effect.
- the silencer casing (silencer casing) 8 can be divided into two in a direction orthogonal to the axial direction of the motor generator shaft (rotary shaft) of the motor / generator (at least one of the motor and the generator).
- the silencer casing (silencer casing) 8 is removed without removing the supply pipe (not shown) from the pipe connection portion 13 and the output power cable (not shown) from the junction box 9, and the silencer (supercharger)
- the muffler 5) can be opened. Therefore, it is possible to simplify the maintenance work of the silencer 5 and to reduce the number of personnel and the maintenance time in the maintenance work.
- Flange 14 and 15 are provided on the joint surface (divided surface) of the upper side silencer casing 8a and the lower side silencer casing 8b, and the flange 14 of the upper side silencer casing (one divided silencer casing) 8a is L-shaped. I decided to make it. Since the L-shaped flange 14 can bend the path through which the air sound leaks from the joint surface between the upper silencer casing 8a and the lower silencer casing 8b into an L shape, leakage of the air sound can be suppressed. .
- the flange 14 of the upper silencer casing 8a is not formed in an L shape and is planar, and the flange 14 of the upper silencer casing 8a can be reduced.
- the L-shaped configuration facilitates positioning of the joint surfaces when the upper silencer casing 8a and the lower silencer casing 8b are fastened. Therefore, the assemblability of the silencer 5 can be improved.
- the rubber sheet (damping material) was sandwiched between the horizontal portion 14a of the flange 14 and the flange 15 (joint surface of the silencer casing 8). Thereby, the air sound which leaks from the joint surface of the upper side silencer casing 8a and the lower side silencer casing 8b can be reduced further.
- the silencer casing 8 includes a suction port 12 that sucks air (outside air) into a side wall in a direction orthogonal to the axial direction, and panels (end faces) 10 a and 10 b provided at end portions in the axial direction of the silencer casing 8. And a plurality of (for example, 16) silencer ribs (silencer ribs) 11 provided on the outer periphery of the motor / generator and connecting between the panels 10a and 10b. Are provided with flanges 14 and 15 extending outward in the axial direction of the silencer casing 8.
- the flanges 14 and 15 so as to extend outward from the respective panels 10a and 10b of the silencer casing 8, the flow of air sucked into the silencer casing 8 from the suction port 12 is not obstructed. Air can be aspirated.
- the silencer ribs 11 are provided in the upper silencer casing 8a and the lower silencer casing 8b, respectively, to increase the rigidity of the upper silencer casing 8a and the lower silencer casing 8b.
- the upper side silencer casing 8a and the lower side silencer casing 8b can be maintained substantially equal to the rigidity of the silencer casing 108 (see FIG. 6A) that has not been divided.
- the shape of the silencer rib 11 is in contact with a motor generator housing rib (housing rib) 16 extending outward from a motor generator housing (housing) 6 provided on the outer periphery of the motor / generator. I decided not to do it. Thereby, the rib 11 for silencers and the rib 16 for motor generator housings do not interfere. Therefore, the silencer casing 8 can be divided and opened.
- each element 7a is arranged in the circumferential direction of the motor generator housing 6 so that the silencer element 7 is divided into two. Therefore, it can be suppressed that the element 7a itself is divided and the sound absorption effect is reduced.
- the electric motor / generator is described as being built in the silencer 5, but the present invention is not limited to this and may be an electric motor or an electric generator.

Abstract
Description
特許文献1では、説明の都合上、半割状態で示されたサイレンサが開示されているが、実際には一体構造とされた過給機である。
本発明の第一態様に係る過給機用消音器は、回転軸を有する電動機および発電機の少なくとも一方の周囲に配置される消音器本体と、該消音器本体を内蔵した消音器ケーシングと、を備え、該消音器ケーシングは、前記回転軸の軸方向に対して直交する方向に分割可能である。
このような過給機用消音器を開放する際に回転軸の軸方向に消音器ケーシングを引き抜く場合には、ジャンクションボックスに接続されている出力電力ケーブルや配管を取り外す必要がある。そのため、これらの取り外し作業に人員や時間が必要となり、メンテナンス性に劣るという問題があった。
また、一方の消音器ケーシングのフランジをL字形状にすることによって、消音器ケーシングを締結する際に分割面同士の位置決めが容易となる。したがって、過給機用消音器の組立性を向上させることができる。
図1には、本実施形態に係るサイレンサを備えているハイブリッド過給機の斜視図が示されており、図2には、従来のサイレンサを備えているハイブリッド過給機の斜視図が示されている。また、図3から図5には、図1に示した本実施形態に係るサイレンサの斜視図と部分拡大構成図が示されている。さらに、図6から図10は、サイレンサ、サイレンサケーシングおよびサイレンサエレメントの構造を示す図であり、各図中の図Aが従来の構造を示し、各図中の図Bが本実施形態に係る構造を示している。また、図11には、本実施形態に係るサイレンサエレメントの部分拡大図が示されている。
サイレンサケーシング(消音器ケーシング)8を電動・発電機(電動機および発電機の少なくとも一方)の電動発電機軸(回転軸)の軸方向に対して直交する方向に2分割可能とすることとした。これにより、配管取り合い部13から供給用配管(図示せず)やジャンクションボックス9から出力電力ケーブル(図示せず)を取り外すことなくサイレンサケーシング(消音器ケーシング)8を取り外して、サイレンサ(過給機用消音器)5を開放することができる。したがって、サイレンサ5のメンテナンス作業の簡易化を図って、メンテナンス作業における人員削減およびメンテナンス時間の低減を図ることができる。
また、上部側サイレンサケーシング8aのフランジ14をL字形状にすることによって、上部側サイレンサケーシング8aと下部側サイレンサケーシング8bとを締結する際の継手面同士の位置決めが容易となる。したがって、サイレンサ5の組立性を向上させることができる。
