Description

本発明は、ハイブリッド車両の冷却システムに係り、より詳しくは、エンジンとモータの動力を駆動力として使用し、エンジンから変速機に連結される動力伝達経路上に従来のトルクコンバータを使用しない形式のハイブリッド車両の冷却システムに関する。   The present invention relates to a cooling system for a hybrid vehicle. More specifically, the present invention uses a power of an engine and a motor as a driving force and does not use a conventional torque converter on a power transmission path connected from the engine to a transmission. The present invention relates to a cooling system for a hybrid vehicle.

ハイブリッド車両は、内燃機関であるエンジンからの動力と電気で駆動されるモータからの動力を共に利用して車両が駆動されるように構成されたものであり、エンジンとモータおよび変速機は、動力を発生させて駆動輪に持続的に供給する過程で熱が発生するため、冷却させるための冷却システムが必要である。
ハイブリッド車両は色々な種類のパワートレインによって構成され、エンジンからの動力とモータからの動力を従来の自動変速機と類似するメカニズムを通じて駆動輪に引き出すことができるようにするものである。この中でも、従来の自動変速機の構成において、比較的多くのエネルギを消耗し、発熱量の多いトルクコンバータを排除した変速機構がある。 The hybrid vehicle is configured such that the vehicle is driven by using both the power from the engine which is an internal combustion engine and the power from the motor driven by electricity. Since heat is generated in the process of generating and continuously supplying the drive wheels, a cooling system for cooling is necessary.
The hybrid vehicle is constituted by various types of power trains, and allows the power from the engine and the power from the motor to be extracted to the drive wheels through a mechanism similar to that of a conventional automatic transmission. Among them, there is a transmission mechanism that consumes a relatively large amount of energy and eliminates a torque converter that generates a large amount of heat in the configuration of a conventional automatic transmission.

図１は、エンジン５００からの動力をクラッチ５０２を介して変速機構５０４に伝達できるように構成されたもので、変速機構５０４にはクラッチ５０２と変速機との間に位置するモータ５０６からの動力も伝達できるように構成されている。変速機構５０４は、従来の自動変速機の構成からトルクコンバータを排除し、残りの歯車列と摩擦要素および油圧制御装置などに該当する構成だけからなっている。   FIG. 1 is configured so that power from the engine 500 can be transmitted to the speed change mechanism 504 via the clutch 502. The speed change mechanism 504 includes power from a motor 506 positioned between the clutch 502 and the transmission. Is also configured to be able to communicate. The transmission mechanism 504 has only a configuration corresponding to the remaining gear train, friction elements, hydraulic control device, and the like, excluding the torque converter from the configuration of the conventional automatic transmission.

上記のようなパワートレインを搭載したハイブリッド車両における冷却対策は、エンジン５００に従来と同様エンジン５００の内部を循環する冷却水による水冷方式を適用し、ウォーターポンプ５０８が冷却水を循環させることで、冷却水がエンジン５００を通過しながらエンジン５００を冷却し、その熱でヒーターコア５１０を通過しながら室内暖房を図り、また一部はＥＴＣ（Ｅｌｅｃｔｒｏｎｉｃ Ｔｈｒｏｔｔｌｅ Ｃｏｎｔｒｏｌ：５１２）装置を通過しながらスロットルボディーの凍結が防止でき、エンジン用ラジエータ５１４を通過しながら冷却水を冷却させるようになっている。   The cooling measures in the hybrid vehicle equipped with the power train as described above are applied to the engine 500 by a water cooling method using cooling water that circulates inside the engine 500 as in the past, and the water pump 508 circulates the cooling water. The cooling water cools the engine 500 while passing through the engine 500, and heats the room while heating the heater core 510, and a part of the throttle body while passing through an ETC (Electronic Throttle Control: 512) device. Freezing can be prevented, and the cooling water is cooled while passing through the radiator 514 for the engine.

一方、モータ５０６と変速機構５０４も冷却が必要であり、従来は、図示したように、エンジン用ラジエータ５１４内にオイルクーラー５１６を取り付け、モータ５０６と変速機構５０４を循環するＡＴＦ（Ａｕｔｏｍａｔｉｃ Ｔｒａｎｓｍｉｓｓｉｏｎ Ｆｌｕｉｄ）をオイルクーラー５１６に循環させることによって冷却がなされている。   On the other hand, the motor 506 and the transmission mechanism 504 also need to be cooled. Conventionally, as shown in the figure, an oil cooler 516 is installed in the engine radiator 514, and the ATF (Automatic Transmission Fluid) circulates between the motor 506 and the transmission mechanism 504. Is cooled by circulating the oil through the oil cooler 516.

しかし、上記のような構成では、車両のコールドスタート時にＡＴＦの温度が迅速に正常レベルに上昇し難く、この場合、ＡＴＦの粘性が大きいため、動力損失が大きいので燃費に不利な側面がある。
図１の右側には、モータ５０６を駆動するための電気動力部品５１８およびＩＳＧ（Ｉｎｔｅｇｒａｔｅｄ Ｓｔａｒｔｅｒ Ｇｅｎｅｒａｔｏｒ：５２０）を冷却するための電装用ラジエータ５２２とウォーターポンプ５２４が備えられている。 However, in the configuration as described above, it is difficult for the temperature of the ATF to quickly rise to a normal level when the vehicle is cold-started. In this case, since the viscosity of the ATF is large, the power loss is large, which is disadvantageous in terms of fuel consumption.
On the right side of FIG. 1, an electric power component 518 for driving the motor 506, and an electric radiator 522 and a water pump 524 for cooling an ISG (Integrated Starter Generator: 520) are provided.

特開２００７−２１６７９１号公報JP 2007-216791 A

本発明は、上記問題点を解決するためになされたものであって、エンジンとモータの動力をクラッチと変速機構を介して駆動輪に伝達するように構成されたハイブリッド車両において、コールドスタート時には、ＡＴＦを迅速に正常レベルの温度に上昇させるようにして摩擦損失の低減による燃費向上を図るようにし、正常走行時には、車両の室内暖房性能の低下を最小化しつつ、モータと変速機構の熱を円滑に冷却させるようにしたハイブリッド車両の冷却システムを提供することにその目的がある。   The present invention has been made to solve the above problems, and in a hybrid vehicle configured to transmit engine and motor power to drive wheels via a clutch and a speed change mechanism, at a cold start, The ATF is quickly raised to a normal level to improve fuel efficiency by reducing friction loss, and during normal driving, the motor and transmission mechanism can smoothly heat while minimizing the deterioration of the vehicle interior heating performance. It is an object of the present invention to provide a cooling system for a hybrid vehicle that is allowed to cool.

本発明は、エンジンとモータの動力をクラッチと変速機構を介して駆動輪に伝達するハイブリッド車両の冷却システムであって、エンジンの冷却水により室内暖房を図るヒーターコアと、エンジンからの冷却水を分岐してヒーターコアとともに供給を受けるようにヒーターコアと並列に設けられ、モータと変速機構を冷却させたＡＴＦが通過するように構成され、エンジンからの冷却水とＡＴＦが熱交換するように構成された熱交換器と、を含んで構成されることを特徴とする。   The present invention is a cooling system for a hybrid vehicle that transmits power of an engine and a motor to drive wheels via a clutch and a transmission mechanism, and includes a heater core that heats the interior with engine cooling water, and cooling water from the engine. It is provided in parallel with the heater core so as to be branched and supplied with the heater core, and is configured such that the ATF that has cooled the motor and the transmission mechanism passes, and the cooling water from the engine and the ATF are configured to exchange heat. And a heat exchanger.

ヒーターコアはエンジンと冷却水連結管によって連結され、熱交換器は冷却水連結管から分岐した分岐連結管に連結され、分岐連結管は冷却水連結管より小さい直径を有すること、を特徴とする。   The heater core is connected to the engine by a cooling water connecting pipe, the heat exchanger is connected to a branch connecting pipe branched from the cooling water connecting pipe, and the branch connecting pipe has a smaller diameter than the cooling water connecting pipe. .

分岐連結管は、冷却水連結管の直径の２０〜６０％の範囲の直径を有することを特徴とする。   The branch connecting pipe has a diameter in the range of 20 to 60% of the diameter of the cooling water connecting pipe.

エンジンの冷却水を冷却するためのエンジン用ラジエータと、冷却水をポンピングするように備えられたウォーターポンプと、冷却水の温度に応じて冷却水をエンジン用ラジエータに供給する状態を転換するサーモスタットと、をさらに備えることを特徴とする。   An engine radiator for cooling engine cooling water, a water pump provided to pump the cooling water, and a thermostat for changing the state of supplying cooling water to the engine radiator according to the temperature of the cooling water; Are further provided.

ヒーターコアとは並列に、熱交換器と直列に連結され、熱交換器を通過する冷却水が通過するように設けられたＥＴＣをさらに備えることを特徴とする。   The ETC is further provided in parallel with the heater core and connected in series with the heat exchanger so that cooling water passing through the heat exchanger passes therethrough.

本発明によれば、エンジンとモータの動力をクラッチと変速機構を介して駆動輪に伝達するように構成されたハイブリッド車両において、コールドスタート時には、ＡＴＦを迅速に正常レベルの温度に上昇させて摩擦損失の低減による燃費向上を図り、正常走行時には、車両の室内暖房性能の低下を最小限にとどめ、モータと変速機構の熱を円滑に冷却させることができる。   According to the present invention, in a hybrid vehicle configured to transmit the engine and motor power to the drive wheels via the clutch and the speed change mechanism, the ATF is quickly raised to a normal level temperature at the time of cold start. The fuel consumption can be improved by reducing the loss, and during normal driving, the decrease in the interior heating performance of the vehicle can be minimized and the heat of the motor and the transmission mechanism can be cooled smoothly.

本発明は、エンジンとモータの動力をクラッチと変速機構を介して駆動輪に伝達するハイブリッド車両に関するものである。
本発明による実施形態は、図２に示すように、エンジン１の冷却水の伝達を受け、室内暖房を図るように設けられたヒーターコア３と、エンジン１からの冷却水をヒーターコア３と分岐して供給を受けるようにヒーターコア３と並列に設けられ、モータ５と変速機構７を冷却させたＡＴＦが通過するように構成され、エンジン１からの冷却水とＡＴＦが互いに熱交換するように構成された熱交換器９とを含んで構成される。
変速機構７は、上述したように、従来の自動変速機の構成からトルクコンバータを除いた構成となっている。 The present invention relates to a hybrid vehicle that transmits power of an engine and a motor to driving wheels via a clutch and a speed change mechanism.
As shown in FIG. 2, the embodiment according to the present invention branches the cooling water from the engine 1 and the heater core 3 provided so as to receive the cooling water from the engine 1 and to perform indoor heating. The ATF is provided in parallel with the heater core 3 so as to be supplied, and is configured such that the ATF that has cooled the motor 5 and the speed change mechanism 7 passes therethrough, so that the cooling water from the engine 1 and the ATF exchange heat with each other. The heat exchanger 9 is configured.
As described above, the transmission mechanism 7 has a configuration in which the torque converter is removed from the configuration of the conventional automatic transmission.

ヒーターコア３はエンジン１と冷却水連結管１１によって連結され、熱交換器９は冷却水連結管１１から分岐した分岐連結管１３に連結され、分岐連結管１３は冷却水連結管１１の直径より小さい直径を有する。
すなわち、エンジン１からの冷却水は主にヒーターコア３に流れ、熱交換器９には相対的に少ない量の冷却水が流れるようにして、ヒーターコア３の暖房性能を大きく低減させないようにしつつ、コールドスタート時には、熱交換器９でモータ５と変速機構７を流れるＡＴＦを迅速に加熱して、ＡＴＦの粘性を迅速に正常レベルに下げることによって、摩擦損失の低減による燃費向上の効果をもたらすようにし、正常運転時には、モータ５と変速機構７から発生する熱を熱交換器９によって円滑に冷却させるようにする。 The heater core 3 is connected to the engine 1 by a cooling water connecting pipe 11, the heat exchanger 9 is connected to a branch connecting pipe 13 branched from the cooling water connecting pipe 11, and the branch connecting pipe 13 is based on the diameter of the cooling water connecting pipe 11. Has a small diameter.
That is, the cooling water from the engine 1 mainly flows to the heater core 3 and a relatively small amount of cooling water flows to the heat exchanger 9 so that the heating performance of the heater core 3 is not greatly reduced. At the cold start, the heat exchanger 9 quickly heats the ATF flowing through the motor 5 and the speed change mechanism 7 to quickly lower the viscosity of the ATF to a normal level, thereby bringing about an effect of improving fuel consumption by reducing friction loss. Thus, during normal operation, heat generated from the motor 5 and the speed change mechanism 7 is smoothly cooled by the heat exchanger 9.

ここで、分岐連結管１３に流動する相対的に少ない量の冷却水によってもモータ５と変速機構７を冷却させるＡＴＦの冷却が円滑になされるのは、パワートレインにおいて、相当な発熱があり、多くのエネルギを消耗するトルクコンバータが排除された状態で、相対的に熱の発生が少ないモータ５と変速機構７だけを冷却させるためである。
すなわち、本発明は、従来のトルクコンバータを排除したハイブリッド車両のパワートレインにおいて、ヒーターコア３の暖房性能の低下を最小限にとどめつつ、コールドスタート時にモータ５と変速機構７の迅速なウォームアップと、正常運転時の適切な冷却性能の確保ができるように最適化したものである。
分岐連結管１３は、冷却水連結管１１の直径を２０〜６０％の範囲内で縮小した直径を有することが好ましい。 Here, the ATF that cools the motor 5 and the speed change mechanism 7 is smoothly cooled even by a relatively small amount of cooling water flowing in the branch connecting pipe 13. This is because only the motor 5 and the speed change mechanism 7 that generate relatively little heat are cooled in a state where a torque converter that consumes much energy is eliminated.
That is, according to the present invention, in the power train of a hybrid vehicle excluding the conventional torque converter, the warming-up of the motor 5 and the speed change mechanism 7 can be quickly performed at the cold start while minimizing the deterioration of the heating performance of the heater core 3. Optimized to ensure proper cooling performance during normal operation.
The branch connecting pipe 13 preferably has a diameter obtained by reducing the diameter of the cooling water connecting pipe 11 within a range of 20 to 60%.

また、図２には、エンジン１の冷却水を冷却するためのエンジン用ラジエータ１５と、冷却水をポンピングするように備えられたウォーターポンプ１７と、冷却水の温度に応じて冷却水をエンジン用ラジエータ１５に供給する状態を転換するサーモスタット１９とが備えられており、エンジン用ラジエータ１５の側面には電装用ラジエータ２１を別途に備えて、モータ５を駆動するのに必要な電気動力部品２３とＩＳＧ２５を冷却させるようにしている。勿論、電装用ラジエータ２１からＩＳＧ２５と電気動力部品２３に冷却水をポンピングするためのウォーターポンプ２７が別に備えられている。   FIG. 2 also shows an engine radiator 15 for cooling the cooling water of the engine 1, a water pump 17 provided to pump the cooling water, and the cooling water for the engine according to the temperature of the cooling water. A thermostat 19 for changing the state of supply to the radiator 15 is provided. An electric radiator 21 is separately provided on a side surface of the engine radiator 15, and an electric power component 23 required for driving the motor 5 is provided. The ISG 25 is allowed to cool. Of course, a water pump 27 for pumping cooling water from the electrical radiator 21 to the ISG 25 and the electric power component 23 is separately provided.

一方、ヒーターコア３とは並列に、熱交換器９とは直列に連結され、熱交換器９を通過する冷却水が通過するようにＥＴＣ２９が設けられた構造を採り、スロットルボディーの凍結を防止できるようにしている。
勿論、ＥＴＣ２９も熱交換器９と直列に設けられるため、分岐連結管１３を通じて供給される比較的に少ない量の冷却水が通過するようになる。 On the other hand, the ETC 29 is provided in parallel with the heater core 3 and in series with the heat exchanger 9 so that the cooling water passing through the heat exchanger 9 can pass therethrough to prevent the throttle body from freezing. I can do it.
Of course, since the ETC 29 is also provided in series with the heat exchanger 9, a relatively small amount of cooling water supplied through the branch connecting pipe 13 passes therethrough.
