Abstract

<P>PROBLEM TO BE SOLVED: To supply a larger amount of cooling medium to a motor even when the rotational speed of a gear for scraping up the cooling medium is low. <P>SOLUTION: An oil guide member 44 is mounted on a rotary shaft 42b of a gear 42a for scraping up cooling oil in order to guide the cooling oil detached from the gear 42a and having reached the rotary shaft when the cooling oil is scraped up by rotation of the gear 42a, in a direction separating from the rotary shaft 42b of the gear 42a. By this, not only the cooling oil scraped up to the upper part of the gear 42a without being detached from the gear 42a but also a part of the cooling oil detached from the gear 42a and scattered in the direction separating from the rotary shaft 42b by the oil guide member 44 can be supplied to a motor using a shaft different from the rotary shaft 42b as a rotary shaft. As a result, a larger amount of cooling oil can be supplied to the motor even when the rotational speed of the gear 42a is low. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

本発明は、車両に関する。   The present invention relates to a vehicle.

従来、この種の車両としては、モータジェネレータと、ケーシングの底部に貯留されたオイルに一部が浸漬されるよう配置されてモータジェネレータからの動力を駆動輪に伝達するデファレンシャルギヤと、を備えるものにおいて、デファレンシャルギヤの回転によってオイルを掻き上げてモータジェネレータに供給するものが提案されている（例えば、特許文献１参照）。この車両では、こうした構成により、オイルを圧送するポンプなどを設けることなくモータジェネレータにオイルを供給してモータジェネレータの潤滑や冷却を行なっている。   Conventionally, this type of vehicle includes a motor generator and a differential gear that is disposed so as to be partly immersed in oil stored in the bottom of the casing and transmits power from the motor generator to drive wheels. In Japanese Patent Application Laid-Open No. H10-227707, a system has been proposed in which oil is picked up by rotation of a differential gear and supplied to a motor generator (see, for example, Patent Document 1). In this vehicle, with such a configuration, the motor generator is lubricated and cooled by supplying oil to the motor generator without providing a pump for pumping oil.

特開２００９−３８９３３号公報JP 2009-38933 A

上述の車両では、デファレンシャルギヤの回転によって掻き上げられるオイルの一部は、掻き上げられている最中にデファレンシャルギヤの縁から外れ、モータに供給されることなく、ケーシングの底部に戻る。デファレンシャルギヤの回転数が低いときには、掻き上げられている最中にディファレンシャルギヤの縁から外れるオイルが多くなり、モータジェネレータに十分なオイルを供給できない場合がある。   In the above-described vehicle, a part of the oil scooped up by the rotation of the differential gear comes off from the edge of the differential gear during the scooping and returns to the bottom of the casing without being supplied to the motor. When the number of rotations of the differential gear is low, there is a case where a large amount of oil comes off from the edge of the differential gear while it is being scooped up, and sufficient oil cannot be supplied to the motor generator.

本発明の車両は、冷却媒体を掻き上げるギヤの回転数が低いときでも、電動機により多くの冷却媒体を供給できるようにすることを主目的とする。   The main object of the vehicle of the present invention is to allow a large amount of cooling medium to be supplied to the electric motor even when the rotational speed of the gear that scoops up the cooling medium is low.

本発明の車両は、上述の主目的を達成するために以下の手段を採った。   The vehicle of the present invention employs the following means in order to achieve the main object described above.

本発明の車両は、
動力を入出力する電動機と、前記電動機の回転軸とは異なる軸を回転軸として回転すると共に貯留部に貯留された冷却媒体に一部が浸漬されたギヤである浸漬ギヤを含み前記電動機から駆動輪に動力を伝達するギヤ機構と、を備え、前記浸漬ギヤの回転によって前記冷却媒体を掻き上げて前記電動機に供給する車両において、
前記浸漬ギヤの回転軸である浸漬ギヤ軸に取り付けられ、前記浸漬ギヤの回転によって掻き上げられる際に該浸漬ギヤから外れて到達した冷却媒体を前記浸漬ギヤ軸から離れる方向に導くガイド部材、
を備えることを特徴とする。 The vehicle of the present invention
Driven from the motor, including an electric motor that inputs and outputs power, and an immersion gear that is a gear that is rotated about a shaft different from the rotation shaft of the electric motor and is partially immersed in a cooling medium stored in a storage unit A vehicle having a gear mechanism for transmitting power to the wheels, and scraping up the cooling medium by rotation of the immersion gear to supply the motor to the motor.
A guide member that is attached to an immersion gear shaft that is a rotation shaft of the immersion gear, and guides the cooling medium that has reached the immersion gear away from the immersion gear shaft when scraped up by the rotation of the immersion gear;
It is characterized by providing.

この本発明の車両では、電動機の回転軸とは異なる軸を回転軸として回転すると共に貯留部に貯留された冷却媒体に一部が浸漬されたギヤである浸漬ギヤの回転軸である浸漬ギヤ軸に、浸漬ギヤの回転によって掻き上げられる際に浸漬ギヤから外れて到達した冷却媒体を浸漬ギヤ軸から離れる方向に導くガイド部材を取り付ける。これにより、浸漬ギヤから外れた冷却媒体の一部をガイド部材によって電動機に供給することができる。この結果、浸漬ギヤが低回転で回転するときでも、より多くの冷却媒体を電動機に供給することができる。   In the vehicle of the present invention, an immersion gear shaft that is a rotation shaft of an immersion gear that is a gear that is rotated with a shaft different from the rotation shaft of the electric motor as a rotation shaft and is partially immersed in a cooling medium stored in a storage portion. In addition, a guide member that guides the cooling medium that has come off the immersion gear when it is scraped up by the rotation of the immersion gear in a direction away from the immersion gear shaft is attached. Thereby, a part of cooling medium removed from the immersion gear can be supplied to the electric motor by the guide member. As a result, even when the immersion gear rotates at a low rotation, more cooling medium can be supplied to the electric motor.

こうした本発明の車両において、前記ギヤ機構を収納するケースに取り付けられて前記ガイド部材を下側から覆う補助部材、を備えるものとすることもできる。こうすれば、冷却媒体がガイド部材から貯留部に移動するのを抑制することができる。   The vehicle according to the present invention may include an auxiliary member that is attached to a case that houses the gear mechanism and covers the guide member from below. If it carries out like this, it can suppress that a cooling medium moves to a storage part from a guide member.

次に、本発明を実施するための形態を実施例を用いて説明する。   Next, the form for implementing this invention is demonstrated using an Example.

図１は、本発明の一実施例としてのハイブリッド自動車２０の構成の概略を示す構成図である。実施例のハイブリッド自動車２０は、図示するように、ガソリンや軽油などを燃料とするエンジン２２と、エンジン２２のクランクシャフトにダンパ２６を介してキャリア軸が接続されると共に駆動輪３９ａ，３９ｂにデファレンシャルギヤ４８やギヤ機構４２を介してリングギヤ軸３２が接続されたプラネタリギヤ３０と、例えば同期発電電動機として構成されて回転子がプラネタリギヤ３０のサンギヤ軸に接続されたモータＭＧ１と、例えば同期発電電動機として構成されて回転子がプラネタリギヤ３０のリングギヤ軸３２に接続されたモータＭＧ２と、を備える。   FIG. 1 is a configuration diagram showing an outline of the configuration of a hybrid vehicle 20 as an embodiment of the present invention. As shown in the drawing, the hybrid vehicle 20 of the embodiment includes an engine 22 that uses gasoline or light oil as fuel, a carrier shaft connected to the crankshaft of the engine 22 via a damper 26, and differentials to drive wheels 39a and 39b. A planetary gear 30 to which the ring gear shaft 32 is connected via the gear 48 or the gear mechanism 42, a motor MG1 having a rotor connected to the sun gear shaft of the planetary gear 30, for example, as a synchronous generator motor, and a synchronous generator motor, for example. And a motor MG2 having a rotor connected to the ring gear shaft 32 of the planetary gear 30.

図２は、モータＭＧ１，ＭＧ２とギヤ機構４２のギヤ４２ａとの配置の様子を示す説明図であり、図３は、図２のギヤ４２ａ，オイルガイド部材４４，補助部材４６をＡ−Ａ面から見たＡＡ視図であり、図４は、図３中のＢ−Ｂ断面を示す断面図である。図２に示すように、モータＭＧ１，ＭＧ２やギヤ機構４２（ギヤ４２ａを含む）は、ハウジング５０に収納されている。ギヤ４２ａは、モータＭＧ１やモータＭＧ２の回転軸とは異なる軸（図２では、モータＭＧ１，ＭＧ２よりも斜め下方に配置された軸）を回転軸４２ｂとし、ハウジング５０の底部の貯留部に貯留された冷却媒体としての冷却オイルにその一部が浸漬されるように配置されており、回転に伴って冷却オイルを上方に掻き上げてモータＭＧ１，ＭＧ２に供給できるようになっている。図２〜図４に示すように、ギヤ４２ａの回転軸４２ｂには、ギヤ４２ａの回転によって掻き上げられる際にギヤ４２ａから外れて到達した冷却オイルを回転軸４２ｂから離れる方向に導くオイルガイド部材４４が取り付けられており、オイルガイド部材４４の下方には、オイルガイド部材４４の管状部４４ａを下側から覆う補助部材４６が設けられている。オイルガイド部材４４は、ギヤ４２ａに対する回転軸４２ｂの軸方向（以下、単に「軸方向」という）の両側（図３中、左右両側）で回転軸４２ｂに取り付けられており、ギヤ４２ａから軸方向に離れるほど外径が大きくなるように拡管された管形状の管状部４４ａと、管状部４４ａとの境界から放射状（実施例では、８方向）に延びるように形成された複数の樋部４４ｂと、を有する。複数の樋部４４ｂは、それぞれ、管状部４４ａで外周側となる面が凹となるよう樋状に形成されており、管状部４４ａから離れるほど、幅が狭くなると共にギヤ４２ａの回転軸４２ｂから離れる方向に延びるよう形成されている。補助部材４６は、管状部４４ａの外周側の面に対向して管状部４４ａを下側から覆うよう形成された覆い部４６ａと、ハウジング５０に固定されて覆い部４６ａを支持する支持部４６ｂと、を有する。このように補助部材４６を設けることにより、オイルガイド部材４４に到達してその表面（外周側の面）に沿って下側に移動した冷却オイルがハウジング５０の底部の貯留部に戻るのを抑制することができる。なお、オイルガイド部材４４や補助部材４６については、それぞれ金属や樹脂など種々の材料により形成するものとすることができる。また、支持部４６ｂは、図２および図３の例では、覆い部４６ａを下方から支持するものとしたが、横方向から支持するものなどとしてもよい。   FIG. 2 is an explanatory view showing the arrangement of the motors MG1, MG2 and the gear 42a of the gear mechanism 42. FIG. 3 shows the gear 42a, the oil guide member 44, and the auxiliary member 46 of FIG. FIG. 4 is a cross-sectional view showing a BB cross section in FIG. 3. As shown in FIG. 2, motors MG <b> 1 and MG <b> 2 and gear mechanism 42 (including gear 42 a) are housed in housing 50. The gear 42a has an axis different from the rotation axis of the motor MG1 or the motor MG2 (in FIG. 2, an axis disposed obliquely below the motors MG1 and MG2) as the rotation axis 42b, and is stored in the storage portion at the bottom of the housing 50. A part of the cooling oil is immersed in the cooling oil as a cooling medium, and the cooling oil can be scraped upward and supplied to the motors MG1 and MG2 as it rotates. As shown in FIGS. 2 to 4, an oil guide member that guides cooling oil that has come off from the gear 42 a when it is scraped up by the rotation of the gear 42 a in a direction away from the rotary shaft 42 b, on the rotating shaft 42 b of the gear 42 a. An auxiliary member 46 is provided below the oil guide member 44 to cover the tubular portion 44a of the oil guide member 44 from below. The oil guide member 44 is attached to the rotating shaft 42b on both sides (right and left sides in FIG. 3) of the rotating shaft 42b with respect to the gear 42a (hereinafter simply referred to as “axial direction”). A tube-shaped tubular portion 44a that is expanded so that the outer diameter becomes larger as it is farther away, and a plurality of flange portions 44b that are formed to extend radially (eight directions in the embodiment) from the boundary between the tubular portion 44a and Have. Each of the plurality of flange portions 44b is formed in a flange shape so that a surface on the outer peripheral side of the tubular portion 44a is concave. The distance from the tubular portion 44a decreases as the distance from the rotation shaft 42b of the gear 42a decreases. It is formed so as to extend in the direction of leaving. The auxiliary member 46 has a cover portion 46a formed to cover the tubular portion 44a from the lower side so as to face the outer peripheral surface of the tubular portion 44a, and a support portion 46b that is fixed to the housing 50 and supports the cover portion 46a. Have. By providing the auxiliary member 46 in this way, it is possible to prevent the cooling oil that has reached the oil guide member 44 and moved downward along the surface (outer peripheral surface) from returning to the reservoir at the bottom of the housing 50 can do. The oil guide member 44 and the auxiliary member 46 can be formed of various materials such as metal and resin. Moreover, although the support part 46b shall support the cover part 46a from the downward direction in the example of FIG. 2 and FIG. 3, it is good also as what supports from the horizontal direction.

このハイブリッド自動車２０では、ギヤ４２ａが回転すると、図２に示すように、ハウジング５０内の冷却オイルがギヤ４２ａの上方に掻き上げられてモータＭＧ１，ＭＧ２に供給される。車両がある程度の車速で走行しているとき（例えば、２０ｋｍ／ｈ以上など）には、ギヤ４２ａの回転数が高いため、こうしたギヤ４２ａの掻き上げにより、モータＭＧ１，ＭＧ２に十分な冷却オイルを供給することができる。   In the hybrid vehicle 20, when the gear 42a rotates, as shown in FIG. 2, the cooling oil in the housing 50 is scraped up above the gear 42a and supplied to the motors MG1 and MG2. When the vehicle is traveling at a certain vehicle speed (for example, 20 km / h or more), since the rotational speed of the gear 42a is high, sufficient cooling oil is supplied to the motors MG1 and MG2 by scooping up the gear 42a. Can be supplied.

また、このハイブリッド自動車２０では、比較的低速で走行しているとき（例えば、２０ｋｍ／ｈ未満など）には、ギヤ４２ａの回転数が低いため、冷却オイルは、ギヤ４２ａの回転によって掻き上げられる際に、ギヤ４２ａの上方まで掻き上げられる前にギヤ４２ａから外れて軸方向に移動しやすくなる。このことを考慮して、実施例では、ギヤ４２ａの回転軸４２ｂにオイルガイド部材４４を取り付けるものとした。これにより、軸方向に移動した冷却オイルの一部は、オイルガイド部材４４の管状部４４ａや樋部４４ｂの表面に到達し、オイルガイド部材４４と共に回転して自重による遠心力を受け、図３の太線矢印に示すように、管状部４４ａ側から樋部４４ｂの先端側に向けてこれらの表面に沿って移動し、樋部４４ｂの先端からギヤ４２ａの回転軸４２ｂから離れる方向に飛散する。こうして飛散した冷却オイルの一部がモータＭＧ１，ＭＧ２に供給される。このようにしてギヤ４２ａの回転軸４２ｂから離れる方向に飛散される冷却オイルの一部をモータＭＧ１，ＭＧ２に供給することにより、ギヤ４２ａの回転数が低いときでも、モータＭＧ１，ＭＧ２により多くの冷却オイルを供給することができる。ギヤ４２ａの回転数が低いときのハウジング５０内の様子の模式的に示す模式図を図５に示す。なお、実施例では、車両が所定の低車速（例えば、１０ｋｍ／ｈや１５ｋｍ／ｈなど）で走行しているときに、ギヤ４２ａから外れてオイルガイド部材４４の表面に到達した冷却オイルがモータＭＧ１，ＭＧ２に最も多く供給されるように、実験などによってオイルガイド部材４４の形状を定めるものとした。   Further, in this hybrid vehicle 20, when the vehicle is traveling at a relatively low speed (for example, less than 20 km / h), the rotation speed of the gear 42a is low, so that the cooling oil is scraped up by the rotation of the gear 42a. At this time, it becomes easy to move in the axial direction after being disengaged from the gear 42a before being swung up to the upper side of the gear 42a. In consideration of this, in the embodiment, the oil guide member 44 is attached to the rotating shaft 42b of the gear 42a. As a result, a part of the cooling oil moved in the axial direction reaches the surface of the tubular portion 44a and the flange portion 44b of the oil guide member 44, rotates together with the oil guide member 44, and receives centrifugal force due to its own weight. As shown by the thick line arrow, it moves along these surfaces from the tubular portion 44a side toward the distal end side of the flange portion 44b, and scatters away from the rotation shaft 42b of the gear 42a from the distal end of the flange portion 44b. Part of the cooling oil thus scattered is supplied to the motors MG1 and MG2. By supplying a part of the cooling oil scattered in the direction away from the rotating shaft 42b of the gear 42a to the motors MG1 and MG2 in this way, even when the rotational speed of the gear 42a is low, more motors MG1 and MG2 are used. Cooling oil can be supplied. FIG. 5 is a schematic diagram schematically showing the inside of the housing 50 when the rotational speed of the gear 42a is low. In the embodiment, when the vehicle is traveling at a predetermined low vehicle speed (for example, 10 km / h, 15 km / h, etc.), the cooling oil that has come off the gear 42a and reaches the surface of the oil guide member 44 is motorized. The shape of the oil guide member 44 is determined by an experiment or the like so as to be supplied most to MG1 and MG2.

以上説明した実施例のハイブリッド自動車２０によれば、冷却オイルを掻き上げるギヤ４２ａの回転軸４２ｂに、ギヤ４２ａの回転によって掻き上げられる際にギヤ４２ａから外れて到達した冷却オイルをギヤ４２ａの回転軸４２ｂから離れる方向に導くオイルガイド部材４４を取り付けるから、ギヤ４２ａから外れずにギヤ４２ａの上方まで掻き上げられる冷却オイルだけでなく、ギヤ４２ａから外れてオイルガイド部材４４によって回転軸４２ｂから離れる方向に飛散する冷却オイルの一部もモータＭＧ１，ＭＧ２に供給することができ、ギヤ４２ａの回転数が低いときでも、モータＭＧ１，ＭＧ２により多くの冷却オイルを供給することができる。   According to the hybrid vehicle 20 of the embodiment described above, the cooling oil that has reached the rotating shaft 42b of the gear 42a that lifts the cooling oil away from the gear 42a when being swung up by the rotation of the gear 42a is rotated by the rotation of the gear 42a. Since the oil guide member 44 that leads in a direction away from the shaft 42b is attached, not only the cooling oil that is scraped up to the upper side of the gear 42a without detaching from the gear 42a but also separated from the rotating shaft 42b by the oil guide member 44 detaching from the gear 42a. A part of the cooling oil scattered in the direction can also be supplied to the motors MG1 and MG2, and even when the rotational speed of the gear 42a is low, more cooling oil can be supplied to the motors MG1 and MG2.

実施例のハイブリッド自動車２０では、オイルガイド部材４４の下方に、オイルガイド部材４４の一部を覆うように補助部材４６を設けるものとしたが、この補助部材４６を設けないものとしてもよい。   In the hybrid vehicle 20 of the embodiment, the auxiliary member 46 is provided below the oil guide member 44 so as to cover a part of the oil guide member 44. However, the auxiliary member 46 may not be provided.

実施例のハイブリッド自動車２０では、ギヤ４２ａに対する軸方向の両側で回転軸４２ｂにオイルガイド部材４４を取り付けるものとしたが、ギヤ４２ａに対する軸方向の片側のみで回転軸４２ｂにオイルガイド部材４４を取り付けるものとしてもよい。   In the hybrid vehicle 20 of the embodiment, the oil guide member 44 is attached to the rotating shaft 42b on both sides in the axial direction with respect to the gear 42a. However, the oil guide member 44 is attached to the rotating shaft 42b only on one side in the axial direction with respect to the gear 42a. It may be a thing.

実施例の主要な要素と課題を解決するための手段の欄に記載した発明の主要な要素との対応関係について説明する。実施例では、モータＭＧ１やモータＭＧ２が「電動機」に相当し、ギヤ４２ａを含むギヤ機構４２が「ギヤ機構」に相当し、ギヤ４２ａの回転軸に取り付けられ、ギヤ４２ａの回転によって掻き上げられる際にギヤ４２ａから外れて到達した冷却オイルをギヤ４２ａの回転軸４２ｂから離れる方向に導くオイルガイド部材４４が「ガイド部材」に相当する。また、オイルガイド部材４４の下方に配置されてオイルガイド部材４４の一部を覆う補助部材４６が「補助部材」に相当する。   The correspondence between the main elements of the embodiment and the main elements of the invention described in the column of means for solving the problems will be described. In the embodiment, the motor MG1 and the motor MG2 correspond to the “electric motor”, and the gear mechanism 42 including the gear 42a corresponds to the “gear mechanism”, which is attached to the rotation shaft of the gear 42a and is scraped up by the rotation of the gear 42a. In this case, the oil guide member 44 that guides the cooling oil that has arrived away from the gear 42a in a direction away from the rotating shaft 42b of the gear 42a corresponds to a “guide member”. The auxiliary member 46 disposed below the oil guide member 44 and covering a part of the oil guide member 44 corresponds to an “auxiliary member”.

以上、本発明を実施するための形態について実施例を用いて説明したが、本発明はこうした実施例に何等限定されるものではなく、本発明の要旨を逸脱しない範囲内において、種々なる形態で実施し得ることは勿論である。   As mentioned above, although the form for implementing this invention was demonstrated using the Example, this invention is not limited at all to such an Example, In the range which does not deviate from the summary of this invention, it is with various forms.
