Description

하이브리드 차량용 동력전달장치{POWER TRANSMISSION DEVICE FOR HYBRID VEHICLE}POWER TRANSMISSION DEVICE FOR HYBRID VEHICLE

본 발명은 하이브리드 차량용 동력전달장치에 관한 것으로서, 보다 상세하게는 이중 모터가 적용되더라도 전장을 축소할 수 있고, 조립성을 개선할 수 있으며, 백래시로 인한 래틀 발생을 방지할 수 있는 하이브리드 차량용 동력전달장치에 관한 것이다.The present invention relates to a power transmission device for a hybrid vehicle, and more particularly, to a power transmission for a hybrid vehicle capable of reducing the overall length, improving assembly, and preventing rattle generation due to backlash even when a dual motor is applied. It's about the device.

일반적으로 하이브리드 차량용 동력전달장치는 자동변속기, 모터, 엔진 및 ISG(Integrated Startor & Generator)가 일렬로 배열되는 레이아웃을 갖는다.In general, a power transmission device for a hybrid vehicle has a layout in which an automatic transmission, a motor, an engine, and an Integrated Starter & Generator (ISG) are arranged in a line.

엔진과 모터를 이용한 하이브리드 자동차에서는 모터를 사용하여 차량의 초기 출발을 도모하고 차량이 일정속도를 갖게 되면 제너레이터, 즉 ISG가 엔진을 시동하여 엔진의 출력과 모터의 출력을 동시에 이용하게 된다.In a hybrid vehicle using an engine and a motor, the motor is used to initiate the vehicle's initial start, and when the vehicle has a certain speed, the generator, that is, the ISG, starts the engine to use the engine's output and the motor's output at the same time.

한편, 하이브리드 차량용 동력전달장치에서 사용되는 모터는 초기 엔진이 구동되지 않을 때 차량 전기 주행을 위해 구동될 수 있다.Meanwhile, a motor used in a power transmission device for a hybrid vehicle may be driven for electric vehicle driving when the initial engine is not driven.

그리고, 최근에는 모터가 1개로 한정되지 않고 2개 이상이 복수개로 배치된다. 일예로, 하이브리드 차량용 동력전달장치에서 2개의 모터가 배치되는 경우, 제1모터는 엔진 시동을 위해 구동되고, 제2모터는 차량 전기 주행을 위해 구동될 수 있다.And, in recent years, the motor is not limited to one, but two or more are arranged in plurality. For example, when two motors are disposed in the power transmission device for a hybrid vehicle, the first motor may be driven to start the engine, and the second motor may be driven for electric vehicle driving.

그러나, 종래에는 엔진 구동력에 의한 충격을 흡수하기 위해 필수적으로 사용되는 토션댐퍼가 모터와 엔진 사이에 배치되므로, 하이브리드 차량용 전달장치의 전장이 길어지고, 토션댐퍼의 다양한 배치로 인해, 토션댐퍼가 2중 스플라인 구조로 엔진과 동력전달장치에 결합되는 경우, 조립의 어려움이 있고, 백래시로 인해 래틀이 발생하는 문제점이 있다.However, in the prior art, since the torsion damper, which is essentially used to absorb the shock caused by the engine driving force, is disposed between the motor and the engine, the overall length of the transmission device for a hybrid vehicle is lengthened, and due to various arrangements of the torsion damper, the torsion damper is 2 When coupled to an engine and a power transmission device in a medium spline structure, there is a problem in that assembly is difficult, and a rattle is generated due to backlash.

따라서, 이를 개선할 필요성이 요청된다.Therefore, there is a need to improve it.

본 발명의 배경기술은 대한민국 공개특허공보 제2009-0020791호(2009.02.27. 공개, 발명의 명칭 : 하이브리드 차량용 동력전달장치)에 게시되어 있다.Background art of the present invention is published in Korean Patent Publication No. 2009-0020791 (published on February 27, 2009, title of invention: power transmission device for hybrid vehicle).

It is an object of the present invention to provide a power transmission device for a hybrid vehicle capable of mitigating the impact of the engine unit and the motor unit.
