Description

本発明は、ポンプハウジング及び中間のハウジングを有し、第１のポンプシャフトを備えたポンプがポンプハウジング内に保持されている、特にサーボステアリング装置のためのモータ／ポンプユニットに関する。   The present invention relates to a motor / pump unit, in particular for a servo steering device, having a pump housing and an intermediate housing, a pump with a first pump shaft being held in the pump housing.

このようなモータ／ポンプユニットは補助の力を提供するために自動車工学の分野で使用される。ステアリング力を補助することに加えて、このようなユニットはまた能動シャシー規制に使用することができる。一般に、一層小型になるようにモータ／ポンプユニットを設計する要求がある。   Such motor / pump units are used in the field of automotive engineering to provide auxiliary power. In addition to assisting the steering force, such units can also be used for active chassis regulation. In general, there is a need to design a motor / pump unit to be even smaller.

ドイツ特許公開第１９６３５４１１Ａ１号公報から、電気モータ及び単シャフトポンプを備えた基礎的なモータ／ポンプユニットが知られており、この場合、モータシャフト及びポンプシャフトは中間のハウジング内において中央の軸受内で結合される。   From DE 196 35 411 A1, a basic motor / pump unit with an electric motor and a single shaft pump is known, in which case the motor shaft and pump shaft are located in a central bearing in an intermediate housing. Combined.

ドイツ特許公開第２９９１６１０８Ｕ１号公報では、モータハウジング及びポンプハウジングへ侵入する単一シャフトを備えたモータ／ポンプユニットが知られており、このシャフト上には、ポンプロータ及びモータのランナーの双方が配置される。
ドイツ特許公開第１９６３５４１１Ａ１号公報 ドイツ特許公開第２９９１６１０８Ｕ１号公報 German Patent Publication No. 29916108U1 discloses a motor / pump unit with a single shaft that penetrates into the motor housing and the pump housing, on which both the pump rotor and the motor runner are arranged. The
German Patent Publication No. 19635411A1 German Patent Publication No. 29916108U1

本発明は機能に関して最適化されるがそれにも拘らず妥当な価格のコンパクトなモータ／ポンプユニットを提供する。   The present invention provides a compact motor / pump unit that is optimized for function but nevertheless reasonably priced.

本発明によれば、最初に述べた形式のモータ／ポンプユニットにおいて、ポンプハウジング及び中間のハウジングはフランジを介して互いに接続され、第１のポンプシャフトはフランジ内で支持される。中間のハウジング内での支持とは異なり、フランジでのポンプシャフトの支持は極めて短い構造のポンプシャフトを許容する。それにより、実際の回転において生じる偏差はより小さく、この理由のため、比較的簡単な補償対策だけで済む。   According to the invention, in a motor / pump unit of the type first mentioned, the pump housing and the intermediate housing are connected to each other via a flange and the first pump shaft is supported in the flange. Unlike support in the intermediate housing, support of the pump shaft at the flange allows a pump shaft with a very short construction. Thereby, the deviation occurring in the actual rotation is smaller and for this reason only a relatively simple compensation measure is required.

このような補償は、特に、第１のポンプシャフトがポンプハウジングを閉じるハウジングカバー内に形成されたブッシュ内で支持されることで達成される。
本発明の好ましい実施の形態によれば、ポンプは第１のポンプシャフトに隣接して配置されかつ同様にフランジ内で支持される第２のポンプシャフトを有する。ポンプシャフトは各々歯車を伴った一部品で構成することができる。 Such compensation is achieved in particular by the first pump shaft being supported in a bush formed in a housing cover that closes the pump housing.
According to a preferred embodiment of the invention, the pump has a second pump shaft which is arranged adjacent to the first pump shaft and which is likewise supported in the flange. The pump shaft can be composed of one part with each gear.

フランジは好ましくはアルミニウム合金のパンチ加工された板である。シール機能及びノイズ減衰を改善するため、フランジは少なくとも部分的にＮＢＲ（ニトリルゴム）を具備する。フランジの寸法はモータ／ポンプユニットの構造上の状態及びフランジの任意の可能な付加的な機能（例えば冷却）に適合させたものとする。   The flange is preferably an aluminum alloy punched plate. In order to improve the sealing function and noise attenuation, the flange is at least partially provided with NBR (nitrile rubber). The dimensions of the flange shall be adapted to the structural state of the motor / pump unit and any possible additional function of the flange (eg cooling).

従来ポンプハウジングとフランジとの間及びフランジとセンタリングハウジングとの間に設けたセンタリングピンにより行っていた中間のハウジングに関するポンプハウジングのセンタリングを簡単化し、改善するため、ポンプハウジングからフランジを通って中間のハウジング内へ突出する少なくとも１つのセンタリングピンを設けることが提案される。   In order to simplify and improve the centering of the pump housing with respect to the intermediate housing, which is conventionally done by the centering pin provided between the pump housing and the flange and between the flange and the centering housing, It is proposed to provide at least one centering pin that projects into the housing.

中間のハウジング上の適所に精確に締結しなければならない別のモータハウジングは、モータ／ポンプユニットの電気モータが中間のハウジングの区分内で保持されるという点で、なしで済ませることができる。
本発明の更なる特徴及ぶ利点は以下の説明及び参照する添付図面から明らかとなろう。 Another motor housing that must be fastened in place on the intermediate housing can be dispensed with in that the electric motor of the motor / pump unit is held in the middle housing section.
Further features and advantages of the invention will become apparent from the following description and the accompanying drawings.

図に示すモータ／ポンプユニット１０はハウジングカバー１２と、ポンプハウジング１４と、中間のハウジング１６と、そのモータシャフト２８のみを示すモータのためのハウジング１８とを有する。モータのステータ、ロータ、軸受及び更なる詳細は本発明にとって必須ではなく、図を明瞭にする理由で図示省略する。   The motor / pump unit 10 shown has a housing cover 12, a pump housing 14, an intermediate housing 16, and a housing 18 for the motor showing only its motor shaft 28. The stator, rotor, bearings and further details of the motor are not essential to the present invention and are not shown for reasons of clarity.

ポンプハウジング１４はハウジングカバー１２によりその一側で閉じられ、他側はフランジ２０を介して中間のハウジング１６に接続される。ポンプハウジングからフランジ２０を通って中間のハウジング１６内へ突出する１又はそれ以上のセンタリングピン２２はこれら３つの素子の正しい位置決めを提供する。中間のハウジング１６において、入口及び出口（図示せず）が閉回路内で搬送される流体のために形成される。   The pump housing 14 is closed on one side by a housing cover 12 and the other side is connected to an intermediate housing 16 via a flange 20. One or more centering pins 22 projecting from the pump housing through the flange 20 and into the intermediate housing 16 provide correct positioning of these three elements. In the intermediate housing 16, inlets and outlets (not shown) are formed for the fluid carried in the closed circuit.

モータシャフト２８はポンプハウジング１４内に保持されたポンプの第１のシャフト３０（駆動シャフト）に結合される。駆動シャフト３０上に配置された第１の歯車３２は第２のポンプシャフト３４上に配置された第２の歯車３６と噛み合う。歯車３２、３６はまたそれぞれポンプシャフト３０、３４と一緒の一部品として構成することができる。２つのポンプシャフト３０、３４は各々ハウジングカバー１２内に形成されたブッシュ３８内で片側を支持され、フランジ２０内で他側を支持される。   The motor shaft 28 is coupled to a first shaft 30 (drive shaft) of the pump held in the pump housing 14. A first gear 32 disposed on the drive shaft 30 meshes with a second gear 36 disposed on the second pump shaft 34. The gears 32, 36 can also be configured as one piece with the pump shafts 30, 34, respectively. The two pump shafts 30 and 34 are each supported on one side in a bush 38 formed in the housing cover 12 and supported on the other side in the flange 20.

フランジ２０は、ハウジングカバー１２のブッシュ３８と同じように、アルミニウム合金からパンチ加工された板として形成される。シール効果及びノイズ減衰を改善するために、フランジ２０は、対応する箇所において、ＮＢＲ（ニトリルゴム）で被覆することができる。   The flange 20 is formed as a plate punched from an aluminum alloy in the same manner as the bush 38 of the housing cover 12. In order to improve the sealing effect and noise attenuation, the flange 20 can be coated with NBR (nitrile rubber) at corresponding locations.
