ハイブリッド駆動装置並びにそれを搭載した自動車

Hybrid driving device and automobile eqipped therewith

Abstract

<P>PROBLEM TO BE SOLVED: To solve a problem wherein a hybrid driving device becomes too large, thereby posing a problem in vehicle mounting property, when the requested driving force of an automobile is large in the hybrid driving device transmitting output of a motor for driving to a driving wheel as assist force. <P>SOLUTION: Output of an internal combustion engine 5 is shifted in a continuously variable manner by a planetary gear 9 for power distribution by controlling a motor 7 for control to transmit it to an output shaft 16. Output of the motor 10<SB>1</SB>for driving is shifted to two speed deceleration rotation by an automatic transmission 30<SB>1</SB>to input it in the output shaft 16. The transmission 30<SB>1</SB>decelerates greatly when the automobile runs at low speed to obtain desired torque and decelerates by small extent when it runs at high speed to obtain desired number of revolutions. <P>COPYRIGHT: (C)2004,JPO
【課題】駆動用モータの出力をアシストとして駆動車輪に伝達するハイブリッド駆動装置は、自動車の要求駆動力が大きい場合、大型となり、車輌搭載性に課題を生じる。 【解決手段】内燃エンジン5の出力を、制御用モータ7を制御することにより動力分配用プラネタリギヤ9にて無段に変速して出力軸16に伝達する。駆動用モータ10 1  の出力は、自動変速装置30 1  により2段の減速回転に変速して出力軸16に入力する。変速装置30 1  は、低車速時大きく減速して所望トルクを得、高車速時に小さく減速して所望回転数を得る。 【選択図】   図1
