- 3 (a) and 4 (a) are plan views viewed from the z direction, and FIGS. 3 (b) and 4 (b) are side views viewed from the y direction.
- the comparative example is the same as the first embodiment except that the position of the fastening point O3 is located above the first embodiment.
- the center of gravity of the electric motor 2 including the gusset 30 is substantially located on the motor rotation axis O2.
- a line connecting the center of gravity of the electric motor 2 and the fastening point O3 when viewed from the y direction is defined as a first line p1 extending in the A direction.
- a line connecting the center of gravity of the electric motor 2 to the fastening point O3 of the comparative example is defined as a second line p2 extending in the B direction.
- the direction B is a direction in which the electric motor 2 vibrates most due to the vibration of the engine 1 when the electric motor 2 is cantilevered without providing the gusset 30, and is generally a vehicle longitudinal component. Is big.
- the vibration direction in the vehicle front-rear direction generated in the mounts M1, M2 is defined as the E direction.
- the B direction and the E direction are considered to be substantially the same direction, the direction is considered to be slightly different depending on various design parameters, but is not particularly limited.
- the fastening point 03 is provided on the second line p2 extending in the B direction for the purpose of effectively regulating the direction in which the electric motor 2 vibrates most.
- FIG. 5 is a schematic plan view showing the vibration state of the power plant when engine vibration occurs in the comparative example.
- the electric motor 2 when the electric motor 2 is cantilevered, it vibrates greatly in the direction B. Therefore, the gusset 30 is provided between the electric motor 2 and the engine 1, and the fastening point O3 is on the second line p2. Arranged.
- the gusset 30 is provided between the electric motor 2 and the engine 1, and the fastening point O3 is on the second line p2.
- it has been found that most of the force generated by the vibration of the electric motor 2 is input to the engine block via the gusset 30. This input causes the engine block to bend, resulting in a large vibration of the power plant as a whole, and it has been found that the vibration cannot be suppressed to an appropriate level.
- FIG. 6 is a side view showing the state of vibration when vibration is generated in the power plant of the vehicle according to the first embodiment
- FIG. 7 is a side view showing force when vibration is generated in the power plant of the vehicle according to the first embodiment. It is.
- the electric motor 2 tries to vibrate in the B direction due to engine vibration.
- the force in the A direction that is input to the engine block EB from the electric motor 2 through the gusset 30 due to the vibration is an E direction component and an F direction component when focusing on the mount M1. And distributed. Therefore, the vibration in the front-rear direction is suppressed, and the vibration in the vertical direction is not recognized as a deterioration of vibration because the sensitivity is low as a driver's discomfort.

- FIG. 8 is a schematic side view for explaining the positional relationship between the first line and the second line in the first embodiment.
- FIG. 8A shows the positional relationship of Example 1
- FIG. 8B shows the positional relationship of the second comparative example.
- the angle ⁇ is set so that the first line p1 passes through the opposite side of the crankshaft 01 from the second line p2. In this case, as shown in FIG.
- the vibration source when the engine block EB vibrates is a roll motion around the crankshaft 01, and the cylinder block 1a, which is separated from the crankshaft 01, Compared to the case 1b, it swings around the crankshaft 01, so it is easy to vibrate greatly.
- the vibration direction of the cylinder block 1a at this time is defined as J.
- the fastening point 03 of the gusset 30 passes through the opposite side of the crankshaft 01 from the second line p2, in other words, if it is provided at a position close to the cylinder block 1a, the vibration direction of the cylinder block 1a The angle formed by J and the first line p1 becomes small, and it becomes difficult to disperse the vibration force generated between the motor housing 2a. Therefore, in the first embodiment, the fastening point 03 of the gusset 30 is set so as to pass the crankshaft 01 side from the second line p2 so that the angle formed by the vibration direction J and the first line p1 is increased. Then, the vibration force generated between the motor housing 2a is dispersed.
- the second line p2 extending in the B direction in which the electric motor 2 vibrates due to the vibration of the engine 1 intersects with an angle ⁇ (first angle). Therefore, the electric motor 2 swings around the fastening point 03, so that it is possible to absorb the mutual vibrations of the engine 1 and the electric motor 2, and the force transmitted to the engine 1 side is suppresse

Therefore, the angle formed by the second line p2 and the vibration direction J of the engine block EB mainly of the cylinder block 1a can be increased, and the vibration force generated between the motor housing 2a can be dispersed.
- the vehicle is a hybrid vehicle that can output a driving force by the electric motor 2. Therefore, when a large electric motor capable of securing a driving force is mounted on the transmission housing 4a, a power plant in which vibration is suppressed can be provided by devising the fastening point 03 of the gusset 30. In particular, when the electric motor 2 is mounted on a shaft different from the crankshaft 01 and a driving force is applied from the electric motor 2 to the driving wheels, the electric motor 2 can be easily mounted.
- the power plant is supported by a pendulum system having mounts M1, M2 above the center of gravity of the power plant and a torque rod TR connected to the vehicle body below the center of gravity of the power plant. That is, by supporting by the pendulum system, transmission of vibrations caused by the roll motion generated on the crankshaft 01 to the vehicle body side is suppressed, and the ride comfort during traveling is improved. At this time, the electric motor 2 is likely to vibrate due to vibration caused by components in the longitudinal direction of the vehicle, but the vibration of the entire power plant can be suppressed by intersecting the first line p1 and the second line p2.

- the first line p1 when viewed from the z direction, has a plane F that is orthogonal to the crankshaft 01 and includes the center of gravity of the electric motor 2, and an angle ⁇ that is smaller than the angle ⁇ . The difference is that they are configured to intersect.
- FIG. 10 is a plan view illustrating a force when vibration is generated in the power plant of the vehicle according to the second embodiment.
- the direction in which the first line p1 extends is defined as the G direction.

- the first line p1 intersects the plane F with an angle ⁇ , the movement of the electric motor 2 in the B direction is dispersed in the G direction and the motor rotating shaft 02 direction. Therefore, it is possible to suppress input due to vibration to the engine block EB.
- the angle ⁇ is smaller than the angle ⁇ . That is, when the first line p1 has an angle ⁇ , a force in the direction of the motor rotation shaft 02 acts on the engine mounting surface 4a2 of the transmission housing 4a and is orthogonal to the crankshaft 01 via the engine block EB. Directional force acts. Then, there is a risk that the engine block EB may vibrate such that it falls over the transmission housing 4a. Specifically, when a vibration as indicated by an arrow H in FIG. 10 occurs between the crankshaft 01 and the engine mounting surface 4a2, and the longitudinal vibration E in the mount M1 increases, the vibration in the longitudinal direction particularly occurs. This is because it cannot be sufficiently suppressed.

- a planetary gear mechanism composed of a plurality of frictional engagement elements may be mounted, and a sub-transmission device capable of appropriately shifting may be mounted.
- the configuration in which the engine is restarted by the starter motor 3 is shown, but other configurations may be used.

図1は、実施例1の車両のパワープラントを具えたハイブリッド車両の駆動系およびその全体制御システムを示す概略系統図である。図1のハイブリッド車両は、エンジン1および電動モータ2を動力源として搭載され、エンジン1は、スタータモータ3により始動する。エンジン1は、Vベルト式無段変速機4を介して駆動輪5に適宜切り離し可能に駆動結合し、Vベルト式無段変速機4は、概略を以下に説明するようなものとする。
インバータ13は、バッテリ12の直流電力を交流電力に変換して電動モータ2へ供給すると共に、電動モータ2への供給電力を加減することにより、電動モータ2を駆動力制御および回転方向制御する。
なお電動モータ2は、上記のモータ駆動のほかに発電機としても機能し、後で詳述する回生制動の用にも供する。この回生制動時はインバータ13が、電動モータ2に回生制動力分の発電負荷をかけることにより、電動モータ2を発電機として作用させ、電動モータ2の発電電力をバッテリ12に蓄電する。
パワープラントは、パワープラントの重心よりも上方に設けられ、パワープラントを懸架するマウントM1,M2と、パワープラントの重心よりも下方に設けられ、パワープラントの車両前後方向の動きを規制するトルクロッドTRと、を有するペンデュラム式マウントにより支持され、パワープラントから車体への振動伝達の抑制と、走行時の乗り心地の改善の両立とを図っている。以下、x方向を車両前後方向、y方向を車幅方向、z方向を車両上下方向と定義して説明する。尚、エンジン1と無段変速機4と電動モータ2の相対的な位置関係が同じであれば、他の方式によりパワープラントを支持してもよい。
(1)エンジン1と、
エンジン1に取り付けられ、変速機ハウジング4aに収装された無段変速機4(変速機)と、
エンジン取り付け面4a2(変速機ハウジング4aのエンジン1側)に取り付けられると共に、エンジン1に留め点03を介して連結される電動モータ2(電動機)と、
を備え、
エンジン1のクランク軸01方向から見て、ガセット30を含む電動モータ2(電動機)の重心と留め点03とを結ぶ第1の線p1と、ガセット30を含む電動モータ2(電動機)の重心から留め点03が無い場合にエンジン1の振動により電動モータ2が振動するB方向に延びる第2の線p2とが角度α(第1角度)を持って交差する。
よって、電動モータ2が留め点03を中心として揺動することで、エンジン1と電動モータ2の互いの振動を吸収することが可能となり、エンジン1側に伝達される力が抑制され、パワープラント全体としての振動の増大を回避できる。
よって、第2の線p2とエンジンブロックEBの主にシリンダブロック1aの振動方向Jとの成す角度を大きくすることが可能となり、モータハウジング2aとの間で生じる振動の力を分散することできる。
よって、駆動力を確保可能な大型の電動機を変速機ハウジング4aに搭載するにあたり、ガセット30の留め点03を工夫することで、振動を抑制したパワープラントを提供できる。特に、クランク軸01とは異なる軸に搭載され、電動モータ2から駆動輪に駆動力を付与する構成の場合、容易に電動モータ2を搭載できる。
すなわち、ペンデュラム方式により支持することで、クランク軸01に発生するロール運動に起因する振動の車体側への伝達を抑制し、走行時の乗り心地の改善を図る。このとき、車両前後方向の成分による振動によって電動モータ2が振動しやすいが、第1の線p1と第2の線p2とが交差することで、パワープラント全体としての振動を抑制できる。
次に、実施例2について説明する。基本的な構成は実施例1と同じであるため、異なる点についてのみ説明する。図9は実施例2の車両のパワープラントの概略を表す模式図である。図9(a)はz方向から見た平面図であり、図9(b)はy方向から見た側面図である。実施例1では、z方向から見たとき、ガセット30はクランク軸01(もしくはモータ回転軸02)に対して垂直に設けられていた。これに対し、実施例2では、z方向から見たとき、第1の線p1が、クランク軸01と直交すると共に電動モータ2の重心を含む平面Fと、角度αより小さな角度βを持って交差するように構成した点が異なる。
エンジン振動によって電動モータ2がB方向(平面F内での振動)に振動しようとする。このとき、第1の線p1は角度βを持って平面Fと交差しているため、電動モータ2のB方向への運動は、G方向とモータ回転軸02方向とに分散される。よって、エンジンブロックEBへの振動による入力を抑制することができる。
(5)第1の線p1が、エンジン1のクランク軸01に直交すると共に電動モータ2の重心を含む平面Fと、角度αより小さな角度β(第2角度)を持って交差することとした。
すなわち、第1の線p1が平面Fと角度βを持って交差することで、ガセット30を介してエンジンブロックEBへ入力される振動を分散することが可能となり、特に車両前後方向に対する振動を抑制できる。また、角度αよりも小さな角度βを設定したことで、エンジンブロックEBが変速機ハウジング4aに対して倒れるような振動を抑制することができ、過剰な分散による特に車両前後方向の振動の悪化を回避できる。
