Description

하이브리드 차량용 동력전달장치{POWER TRANSMISSION DEVICE FOR HYBRID VEHICLE}Hybrid vehicle power transmission system {POWER TRANSMISSION DEVICE FOR HYBRID VEHICLE}

본 발명은 하이브리드 차량용 동력전달장치에 관한 것으로서, 보다 상세하게는 이중 모터가 적용되더라도 전장을 축소할 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 device for a hybrid vehicle capable of reducing the overall length even when a dual motor is applied.

일반적으로 하이브리드 차량용 동력전달장치는 자동변속기, 모터, 엔진 및 ISG(Integrated Startor & Generator)가 일렬로 배열되는 레이아웃을 갖는다.In general, a power transmission system for a hybrid vehicle has a layout in which an automatic transmission, a motor, an engine, and an Integrated Startor & 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, a motor is used to start the vehicle initially and when the vehicle has a constant speed, a generator, i.e., ISG, starts the engine and uses both the engine's output and the motor's output at the same time.

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

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 number of motors is not limited to one, and two or more are arranged in plural. For example, when two motors are disposed in a power transmission system for a hybrid vehicle, a first motor may be driven to start an engine, and a 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, 토션댐퍼를 지지하기 위한 별도의 중량물이 설치되어야 하는 문제점이 있다. 따라서, 이를 개선할 필요성이 요청된다.However, in the related 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 a separate weight to support the torsion damper must be installed There is a problem. Therefore, there is a need to improve this.

상기와 같은 구조를 갖는 본 발명의 일 실시예에 따른 하이브리드 차량용 동력전달장치의 조립 및 작동을 설명하면 다음과 같다.The assembly and operation of the hybrid vehicle power transmission device according to an embodiment of the present invention having the above structure will be described as follows.

제2모터부(22)의 내부에 제2로터부(32)를 배치시키고, 전달부(50)와 제2로터부(32) 사이에 클러치부(60)를 배치시킨다. 이때, 제2모터부(22)는 커버외벽부(11)의 내측에 장착되고, 제2로터부(32)는 커버내벽부(12)에 지지된다.The second rotor unit 32 is disposed inside the second motor unit 22, and the clutch unit 60 is disposed between the transmission unit 50 and the second rotor unit 32. At this time, the second motor part 22 is mounted inside the cover outer wall part 11, and the second rotor part 32 is supported by the cover inner wall part 12.

그리고, 제1모터부(21)의 내부에 제1로터부(31)를 배치시킨다. 이때, 제1모터부(21)는 커버외벽부(11)의 내측에 장착되고, 제1로터부(31)는 커버내벽부(12)에 지지된다.Then, the first rotor part 31 is disposed inside the first motor part 21. At this time, the first motor part 21 is mounted inside the cover outer wall part 11, and the first rotor part 31 is supported by the cover inner wall part 12.

또한, 제1모터부(21)와 제1로터부(31)를 커버하도록 덮개판부(81)를 배치시키고, 덮개체결부(82)를 이용하여 덮개판부(81)를 커버외벽부(11)에 볼트 결합하고, 덮개실링부(83)를 이용하여 덮개판부(81)와 제1댐퍼부(41)를 실링 처리한다.In addition, the cover plate portion 81 is disposed to cover the first motor portion 21 and the first rotor portion 31, and the cover plate portion 81 is attached to the cover outer wall portion 11 using the cover fastening portion 82. It is bolted to, and the cover plate part 81 and the first damper part 41 are sealed using the cover sealing part 83.

덮개부(80) 장착이 완료되면, 스플라인 결합을 위해 커넥터부(90)를 제1댐퍼부(41)에 삽입시키고, 외측으로 노출된 커넥터부(90)와 엔진부(100)를 결합시킨다.When the mounting of the cover part 80 is completed, the connector part 90 is inserted into the first damper part 41 for spline coupling, and the connector part 90 exposed to the outside and the engine part 100 are coupled.

상술한 조립 구조는 제1댐퍼부(41)와 제2댐퍼부(42)를 제1모터부(21)의 내부에 배치하여 전장 단축을 기대할 수 있다. 그리고, 제1로터부(31)와 제1댐퍼부(41)가 직접 볼트 결합되므로, 별도의 댐퍼용 매스(mass)가 생략될 수 있다. 즉, 제1댐퍼부(41)에 결합된 제1로터부(31)의 무게가 상당하여 댐퍼용 매스 기능을 수행할 수 있다. 또한, 제1댐퍼부(41)와 제2댐퍼부(42)가 이중으로 연결된 구조를 채택하여 저강성화가 가능하다. 이로 인해 제1댐퍼부(41)의 무게를 줄이고 구조를 단순화할 수 있다.In the above-described assembly structure, the first damper part 41 and the second damper part 42 are arranged inside the first motor part 21 to reduce the overall length. In addition, since the first rotor part 31 and the first damper part 41 are directly bolted together, a separate mass for a damper may be omitted. That is, the weight of the first rotor part 31 coupled to the first damper part 41 is significant, so that a mass function for a damper may be performed. In addition, it is possible to reduce the rigidity by adopting a structure in which the first damper part 41 and the second damper part 42 are double-connected. Accordingly, it is possible to reduce the weight of the first damper part 41 and simplify the structure.

그리고, 제1모터부(21)가 구동되면, 제1로터부(31)가 회전되고, 제1로터부(31)와 연결된 제1댐퍼부(41)가 엔진부(100)를 회전시켜 엔진부(100)의 시동을 유도할 수 있다.And, when the first motor unit 21 is driven, the first rotor unit 31 is rotated, and the first damper unit 41 connected to the first rotor unit 31 rotates the engine unit 100 It is possible to induce the start of the unit 100.

엔진부(100)가 구동되면, 엔진부(100)의 회전력이 제1댐퍼부(41) 및 제2댐퍼부(42)를 통해 전달부(50)에 전달되고, 클러치부(60)를 통해 출력부(70)로 이동되어 차량 주행이 실시될 수 있다.When the engine unit 100 is driven, the rotational force of the engine unit 100 is transmitted to the transmission unit 50 through the first damper unit 41 and the second damper unit 42, and through the clutch unit 60 The vehicle may be driven by moving to the output unit 70.

본 발명의 일 실시예에 따른 하이브리드 차량용 동력전달장치(1)는 모터부(20)의 내부에 토션댐퍼부(40)가 배치되므로 전장 길이 축소가 가능하고, 토션댐퍼부(40)가 엔진부(100) 및 모터부(20)의 충격을 완화할 수 있다.In the hybrid vehicle power transmission device 1 according to an embodiment of the present invention, since the torsion damper unit 40 is disposed inside the motor unit 20, the overall length can be reduced, and the torsion damper unit 40 is the engine unit. It is possible to alleviate the impact of 100 and the motor unit 20.
