Description

本発明は、ハイブリッド車両用駆動装置に関する。 The present invention relates to a drive device for a hybrid vehicle.

従来のハイブリッド車両用動力伝達装置として、特許文献１に記載されるものが知られている。特許文献１に記載のハイブリッド車両用動力伝達装置は、エンジンに取り付けられた変速機ハウジングのエンジン側に取り付けられると共に、エンジンに留め点を介して連結される電動機を備え、エンジンのクランク軸方向から見て、電動機の重心と留め点とを結ぶ線と、留め点が無い場合にエンジンの振動により電動機が振動する方向に延びる線とが交差するようにしている。 As a conventional power transmission device for a hybrid vehicle, the one described in Patent Document 1 is known. The power transmission device for a hybrid vehicle described in Patent Document 1 is attached to an engine side of a transmission housing attached to the engine and includes an electric motor that is connected to the engine via a fastening point, and from the crankshaft direction of the engine. As seen, the line connecting the center of gravity of the electric motor and the stopping point intersects with the line extending in the direction in which the electric motor vibrates due to the vibration of the engine when there is no stopping point.

これにより、特許文献１に記載のハイブリッド車両用動力伝達装置は、電動機が振動する際に、留め点が無い場合の直線運動を、留め点を中心とした揺動運動に変換することが可能となり、電動機から留め点を介してエンジン側に入力される力を分散することでパワープラント全体の振動を抑制できる。 As a result, the power transmission device for a hybrid vehicle described in Patent Document 1 can convert a linear motion when there is no fastening point into a swinging motion around the fastening point when the electric motor vibrates. , The vibration of the entire power plant can be suppressed by distributing the force input from the electric motor to the engine side through the fastening points.

車両１の前進時におけるエンジン走行時においては、エンジン８の動力が入力軸１１から所定の変速段を成立する入力ギヤ１６Ａから入力ギヤ１６Ｆのいずれかを介して出力ギヤ１７Ａから出力ギヤ１７Ｆのいずれかに伝達される。 When the vehicle is moving forward when the vehicle is moving forward, the power of the engine 8 is transmitted from the input shaft 11 to any of the output gear 17A to the output gear 17F via any of the input gear 16A to the input gear 16F that establishes a predetermined shift speed. Is transmitted to.

これにより、前進用出力軸１２のファイナルドライブギヤ１７Ｇからファイナルドリブンギヤ１５Ａに動力が伝達され、エンジン８の動力がディファレンシャル装置１５の差動機構１５Ｃによって左右のドライブシャフト２４Ｌ、２４Ｒに分配されて駆動輪に伝達され、車両１が前進走行する。 As a result, the power is transmitted from the final drive gear 17G of the output shaft 12 for forward drive to the final driven gear 15A, and the power of the engine 8 is distributed to the left and right drive shafts 24L and 24R by the differential mechanism 15C of the differential device 15 to drive the drive wheels. The vehicle 1 travels forward.

一方、車両１の前進時にモータ３２の駆動力を作用させる時は、モータ３２の動力がモータ軸３２Ｂから第１のドライブギヤ３４を介して第１のドリブンギヤ３５Ａに伝達される。 On the other hand, when the driving force of the motor 32 is applied when the vehicle 1 moves forward, the power of the motor 32 is transmitted from the motor shaft 32B to the first driven gear 35A via the first drive gear 34.

次いで、モータ３２の動力は、第２のドライブギヤ３５Ｂ、第２のドリブンギヤ３６Ａおよび第３のドライブギヤ３６Ｂを介して４速段用の出力ギヤ１７Ｄに伝達される。 Next, the power of the motor 32 is transmitted to the output gear 17D for the fourth speed via the second drive gear 35B, the second driven gear 36A and the third drive gear 36B.

減速機構３３は、ドライブギヤ３４、３５Ｂ、３６Ｂおよびドリブンギヤ３５Ａ、３６Ａの直径および歯数が任意の減速比となるように設定されているので、モータ３２の動力が減速されて前進用出力軸１２に伝達される。 In the reduction mechanism 33, the drive gears 34, 35B, 36B and the driven gears 35A, 36A are set such that the diameters and the numbers of teeth of the reduction gears 33 have an arbitrary reduction ratio.

A mount attachment portion 31 to which the mount device 70 is attached is formed in front of the bulging portion 7H on the upper surface of the left case body portion 7G.

これにより、重量の大きいモータ３２の荷重をマウント取付部３１に受け持たせることができ、変速機ケース５の振動を抑制できるので、車両の商品性を向上させることができる。この結果、変速機の振動を抑制することができる。 As a result, the load of the heavy motor 32 can be carried by the mount mounting portion 31, and the vibration of the transmission case 5 can be suppressed, so that the commercialability of the vehicle can be improved. As a result, the vibration of the transmission can be suppressed.

Can be suppressed.

本実施例の駆動装置４によれば、シフトユニット４１は、変速機構６１に対して油圧を作用させるバルブユニット４１Ｂが少なくとも取付けられるベースプレート４１Ａを有し、レフトケース７は、ベースプレート４１Ａが取付けられるベースプレート取付部３０を有している。 According to the drive device 4 of the present embodiment, the shift unit 41 has the base plate 41A to which at least the valve unit 41B that applies hydraulic pressure to the transmission mechanism 61 is attached, and the left case 7 is the base plate to which the base plate 41A is attached. It has a mounting portion 30.

また、ベースプレート取付部３０は、上下方向において、マウント取付部３１よりも下方に配置され、マウント取付部３１と弾性部材７３との間に、バルブユニット４１Ｂの大部分が配置されている。 Further, the base plate mounting portion 30 is arranged below the mount mounting portion 31 in the vertical direction, and most of the valve unit 41B is arranged between the mount mounting portion 31 and the elastic member 73.

これにより、比較的上下に長いバルブユニット４１Ｂを下方に配置できるとともに、変速機ケース５を車体２に弾性支持する弾性部材７３の下側近傍にバルブユニット４１Ｂの重心が配置されるので、重量物であるバルブユニット４１Ｂを揺動中心（場所不明）の近傍に配置でき、振動を効果的に抑制することができる。 As a result, the valve unit 41B that is relatively long in the vertical direction can be disposed below, and the center of gravity of the valve unit 41B is disposed near the lower side of the elastic member 73 that elastically supports the transmission case 5 on the vehicle body 2. The valve unit 41B, which is a unit, can be arranged in the vicinity of the swing center (location unknown), and vibration can be effectively suppressed.
