Description

자동 변속기의 파워 트레인{POWER TRAIN FOR AUTOMATIC TRANSMISSION}Power train of automatic transmission {POWER TRAIN FOR AUTOMATIC TRANSMISSION}

본 발명은 전진 10속 변속단과 후진 1속 변속단을 구현할 수 있는 자동 변속기의 파워 트레인에 관한 것이다.The present invention relates to a power train of an automatic transmission capable of implementing 10 forward gears and 1 reverse gear gear.

일반적으로 하이브리드 차량은 서로 다른 두 종류 이상의 동력원을 효율적으로 조합하여 차량을 구동시킨다. 하이브리드 차량은 연료(가솔린 등 화석연료)를 연소시켜 회전력을 얻는 엔진과 배터리 전력으로 회전력을 얻는 모터에 의해 구동하는 차량이다.Generally, hybrid vehicles drive the vehicle by efficiently combining two or more different types of power sources. A hybrid vehicle is a vehicle that is driven by an engine that obtains rotational force by burning fuel (fossil fuels such as gasoline) and a motor that obtains rotational force by battery power.

하이브리드 차량은 통상적으로 엔진과 모터를 사용하는데, 저속에서는 상대적으로 저속토크 특성이 좋은 모터를 주 동력원으로 사용하고, 고속에서는 상대적으로 고속토크 특성이 좋은 엔진을 주 동력원으로 사용한다. 이에 따라, 하이브리드 차량은 저속구간에서 화석 연료를 사용하는 엔진의 작동이 정지되고 모터를 사용하기 때문에 연비 개선과 배기가스의 저감에 우수한 효과가 있다.Hybrid vehicles typically use engines and motors. At low speeds, a motor with relatively good low-speed torque characteristics is used as the main power source, and at high speeds, an engine with relatively good high-speed torque characteristics is used as the main power source. Accordingly, hybrid vehicles have excellent effects in improving fuel efficiency and reducing exhaust gases because the engine using fossil fuels stops operating at low speeds and the motor is used.

하이브리드 차량은 구동을 위해 모터의 회전력만을 이용하는 순수 전기자동차 모드인 EV(Electric Vehicle) 모드와, 엔진의 회전력을 주동력으로 하면서 모터의 회전력을 보조동력으로 이용하는 HEV(Hybrid Electric Vehicle) 모드 등의 운전모드로 주행하며, 엔진의 시동을 통해 EV 모드에서 HEV 모드로의 모드 변환이 이루어진다.Hybrid vehicles operate in EV (Electric Vehicle) mode, which is a pure electric vehicle mode that uses only the rotational power of the motor for driving, and HEV (Hybrid Electric Vehicle) mode, which uses the rotational power of the engine as the main power and the rotational power of the motor as auxiliary power. It drives in mode, and the mode is converted from EV mode to HEV mode by starting the engine.

하이브리드 차량에 변속을 위한 자동 변속기의 파워 트레인이 장착될 수 있다. 후진 주행을 위하여 후진 변속을 하게 되면, 자동 변속기의 파워 트레인에 입력되는 전진 구동력을 자동 변속기의 파워 트레인에 포함된 후진 기어열에서 역방향으로 동력을 전환 출력함으로써 후진 주행이 이루어지게 된다.Hybrid vehicles may be equipped with an automatic transmission powertrain for shifting. When shifting backwards to drive backwards, the forward driving force input to the power train of the automatic transmission is converted into power in the reverse direction and output from the reverse gear train included in the power train of the automatic transmission, thereby driving backwards.

그런데 종래의 자동 변속기의 파워 트레인에 의한 후진단은 엔진의 동력에 의한 방식이 대부분이었다.However, most reverse gears using the power train of conventional automatic transmissions were driven by engine power.
