Abstract

본 발명은 조립구멍이 구비되는 엔진 클러치 리테이너; 상기 조립구멍을 통해 조립되는 결합부재; 및 상기 조립구멍을 밀폐하는 밀폐커버; 를 포함하는 하이브리드 변속기의 조립구조를 제공한다.

Description

하이브리드 변속기의 조립구조
본 발명은 하이브리드 변속기의 조립구조에 관한 것이다.
일반적으로 하이브리드 차량은 서로 다른 두 종류 이상의 동력원을 효율적으로 조합하여 차량을 구동시키는 것을 의미한다. 하이브리드 차량은 연료(가솔린 등 화석연료)를 연소시켜 회전력을 얻는 엔진과 배터리 전력으로 회전력을 얻는 모터에 의해 구동하는 차량을 의미한다.
이러한 하이브리드 차량은 엔진뿐만 아니라 모터를 보조동력원으로 채택하여 배기가스 저감 및 연비 향상을 도모할 수 있는 미래형 차량으로 연구가 활발히 진행되고 있다.
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.
하이브리드 차량용 구동장치는 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.
한편, 기존 하이브리드 변속기에서 엔진 클러치 리테이너를 회전 가능하도록 지지하는 베어링을 조립하기 위해서는 볼트 등과 같은 결합부재를 이용하여 베어링을 서포트에 고정할 수밖에 없다. 이때, 엔진 클러치 리테이너는 베어링과 엔진 클러치 피스톤 사이에 위치하기 때문에 볼트의 조립작업을 위해 엔진 클러치 피스톤 측에서 베어링을 향하여 관통되는 조립구멍이 필요하다. 엔진 클러치 리테이너에 조립구멍이 마련될 경우 조립구멍을 통해 엔진 클러치 피스톤 측에서 베어링 측으로 볼트를 삽입한 다음 볼트로 베어링을 서포트에 고정하는 작업을 손쉽게 수행할 수 있다.
그러나 기존 엔진 클러치 리테이너에 조립구멍을 형성할 경우 엔진 클러치 리테이너와 엔진 클러치 피스톤 사이로 공급되는 작동유가 조립구멍을 통해 베어링 쪽으로 유출됨에 따라 엔진 클러치의 작동에 필요한 작동유압이 형성되지 못하여 엔진 클러치의 작동이 불가한 문제가 발생하였다.
이에 대하여, 본 발명은 엔진 클러치 리테이너에 구비되는 조립구멍을 밀폐커버로 차단하여 엔진 클러치 리테이너와 엔진 클러치 피스톤 사이에 작동유압이 형성되게 함으로써, 엔진 클러치의 작동이 원활하게 이루어질 수 있도록 하는 메커니즘을 제시하고자 한다.

기존 엔진 클러치 리테이너에 조립구멍을 형성할 경우 엔진 클러치 리테이너와 엔진 클러치 피스톤 사이로 공급되는 작동유가 조립구멍을 통해 베어링 쪽으로 유출됨에 따라 엔진 클러치의 작동에 필요한 작동유압이 형성되지 못하여 엔진 클러치의 작동이 불가한 문제가 발생하였다. 이에 대하여, 본 발명은 엔진 클러치 리테이너에 구비되는 조립구멍을 밀폐커버로 차단하여 엔진 클러치 리테이너와 엔진 클러치 피스톤 사이에 작동유압이 형성되게 함으로써, 엔진 클러치의 작동이 원활하게 이루어질 수 있도록 하는 메커니즘을 제시하고자 한다.

도 1 내지 3에 도시된 바와 같이, 본 발명은 엔진 클러치 리테이너(110)에 볼트(bolt) 등과 같은 결합부재(140)가 지나갈 수 있는 조립구멍(111)을 천공하여 조립구멍(111)을 통해 결합부재(140)의 조립완료 후 조립구멍(111)을 밀폐커버(150)로 막아 조립구멍(111)을 통한 오일 누유를 방지함으로써 엔진 클러치의 작동유압(P)이 리크(leak)되지 않도록 하는 것을 기술적 특징으로 한다.
구체적은 본 발명은 조립구멍(111)을 구비하는 엔진 클러치 리테이너(110) 및 조립구멍(111)을 통해 조립대상(120)이 고정되도록 조립하는 결합부재(140)를 포함한다.
엔진 클러치 리테이너(110)는 하이브리 변속기 내부에서 조립대상(120)과 엔진 클러치 피스톤(130) 사이에 위치한다. 일예로서 엔진 클러치 리테이너(110)는 모터 로터와 일체형으로 구성될 수 있다. 엔진 클러치 리테이너(110)의 조립구멍(111)은 베어링 등과 같은 조립대상(120)을 향하여 관통 형성된다. 일예로서 조립대상(120)은 더블볼베어링(double ball bearing)일 수 있다.
하이브리드 차량에 적용하는 모터는 모터 스테이터(101), 마그넷(102), 엔진 클러치 리테이너(110)와 일체형으로 구성되는 모터 로터를 포함한다.
조립구멍(111)은 결합부재(140)의 조립시 결합부재(140)가 자유로이 통과할 수 있고 조립작업이 원활히 이루어질 수 있는 충분한 크기의 구멍으로 형성되어야 한다.
결합부재(140)는 조립구멍(111)을 통해 조립대상(120) 측으로 삽입되어 조립대상(120)이 서포트(170) 등과 같은 고정대상물에 고정되도록 조립대상(120)을 조립한다. 일예로서 결합부재(140)는 볼트(bolt)일 수 있다.
결합부재(140)의 조립작업 후 조립구멍(111)은 밀폐커버(150)에 의해 밀폐된다. 조립구멍(111)이 밀폐커버(150)에 의해 밀폐됨에 따라 조립구멍(111)을 통한 오일 누유를 방지함으로써 엔진 클러치의 작동유압(P)이 리크(leak)되지 않도록 할 수 있다. 이로 인해 엔진 클러치 리테이너(110)와 엔진 클러치 피스톤(130) 사이에 작동유압(P)이 형성되어 엔진 클러치의 작동이 원활하게 이루어질 수 있다.
엔진 클러치 리테이너(110)에 수용부(112)가 마련된다. 수용부(112)에 밀폐커버(150)가 대응 결합된다. 수용부(112)는 엔진 클러치 피스톤(130) 쪽에 구비되고, 조립구멍(111)은 조립대상(120) 쪽에 구비된다. 수용부(112)는 조립구멍(111)과 동심원을 이루며 연통된다. 수용부(112)는 조립구멍(111)보다 더 큰 구멍으로 구성된다.

구체적으로 함몰부(152)는 함몰면(152a), 내륜부(152c) 및 외륜부(152d)를 포함한다.
함몰면(152a)에는 공구 물림부(152b)가 구비된다. 일예로서 공구 물림부(152b)는 리브(rib)일 수 있다. 집게 등과 같은 공구를 사용하여 공구 물림부(152b)를 잡아 당기면 조립 상태의 밀폐커버(150)를 쉽게 분해할 수 있다.
일예로서, 함몰면(152a)에 2개의 공구 물림부(152b)를 서로 마주보도록 구비하는 것이 바람직하다. 2개의 공구 물림부(152b)에 2개의 공구를 물려 밀폐커버(150)를 잡아당기면 밀폐커버(150)를 당기는 힘이 양측으로 고르게 작용하므로 조립 상태의 밀폐커버(150)를 쉽게 분해할 수 있다.
내륜부(152c)는 함몰면(152a)과 이어지고 내륜을 구성한다. 내륜부(152c)는 함몰면(152a)의 내측에 구성된다. 내륜부(152c)는 안쪽에서 바깥쪽으로 갈수록 폭이 넓어지는 경사면으로 구성된다.
외륜부(152d)는 함몰면(152a)과 이어지고 외륜을 구성한다. 외륜부(152d)는 함몰면(152a)의 외측에 구성된다. 외륜부(152d)는 안쪽에서 바깥쪽으로 갈수록 폭이 넓어지는 경사면으로 구성된다. 외륜부(152d)는 내륜부(152c)보다 더 큰 구경의 외륜으로 구성된다.
조립대상(120)에 테두리부(121)가 구비된다. 테두리부(121)는 조립대상(120)의 외주에서 외측 방향으로 연장 형성된다. 테두리부(121)에 결합구멍(121a)이 구비된다. 일예로서, 결합구멍(121a)은 볼트 머리 부위가 수용될 수 있도록 볼트 머리에 부합하는 형상으로 구성되는 것이 바람직하다.
결합부재(140)는 조립구멍(111)을 통과하여 결합구멍(121a)에 삽입된 상태에서 서포트(170)에 나사 결합된다.
조립구멍(111)과 결합구멍(121a) 및 서포트(170)의 나사 결합 부위는 일직선상에 위치한 상태에서 결합부재(140)의 조립이 이루어진다.
조립대상(120)은 결합부재(140)에 의해 서포트(170)에 고정된 상태에서 엔진 클러치 리테이너(110)를 회전 가능하도록 지지한다.
다음은 본 발명의 조립과정에 대해 설명한다.
도 4는 본 발명의 바람직한 일 실시예에 따른 조립 과정을 나타내는 도면이다.
도 4와 같이, 엔진 클러치 리테이너(110)에 조립대상(120)을 압입한다. 이와 같이 조립대상(120)을 엔진 클러치 리테이너(110)의 조립 부위에 압입하면 조립대상(120)의 테두리부(121)에 구비되는 결합구멍(121a)이 자연스럽게 조립구멍(111)과 일치하게 된다.
엔진 클러치 피스톤(130) 쪽에서 결합부재(140)를 조립구멍(111)에 삽입한다. 조립구멍(111)에 삽입된 결합부재(140)는 결합구멍(121a)을 통해 서포트(170)의 조립 부위에 나사 결합된다.
이와 같이 결합부재(140)에 의해 조립대상(120)이 서포트(170)에 고정되도록 조립한 다음 조립구멍(111)을 밀폐커버(150)로 밀폐한다.
구체적으로 밀폐커버(150)를 엔진 클러치 리테이너(110)의 수용부(112)에 대응 결합하면 수용부(112)와 연통되어 있는 조립구멍(111)이 밀폐커버(150)에 의해 밀폐된다. 이로 인해, 엔진 클러치 리테이너(110)와 엔진 클러치 피스톤(130) 사이에 작동유압이 조립구멍(111)을 통해 조립대상(120) 쪽으로 유출되는 것을 방지할 수 있다.
밀폐커버(150)의 조립 완료 후 엔진 클러치 피스톤(130)과 클러치 디스크(180) 등의 순으로 순차적으로 조립을 진행한다.
수용부(112)에 밀폐커버(150)를 결합시 밀폐커버(150) 외주의 수밀부재(160)가 수용부(112)의 내주면에 긴밀히 밀착되어 견고한 수밀 상태가 이루어질 수 있다.
살펴본 바와 같이 본 발명은 더블볼베어링 등과 같은 조립대상에 의한 엔진 클러치 리테이너 지지의 강건화를 통해 하이브리드 차량의 소음진동을 저감하고 성능을 향상시킬 수 있다. 또한, 본 발명은 엔진 클러치 리테이너에 구비되는 조립구멍을 밀폐커버로 차단하여 엔진 클러치 리테이너와 엔진 클러치 피스톤 사이에 작동유압이 형성되게 함으로써, 엔진 클러치의 작동이 원활하게 이루어질 수 있다.
이상의 설명은 본 발명의 기술 사상을 예시적으로 설명한 것에 불과한 것으로서, 본 발명이 속하는 기술 분야에서 통상의 지식을 가진 자라면 본 발명의 본질적인 특성에서 벗어나지 않는 범위 내에서 다양한 수정, 변경 및 치환이 가능할 것이다. 따라서, 본 발명에 개시된 실시예 및 첨부된 도면들은 본 발명의 기술 사상을 한정하기 위한 것이 아니라 설명하기 위한 것이고, 이러한 실시예 및 첨부된 도면에 의하여 본 발명의 기술 사상의 범위가 한정되는 것은 아니다. 본 발명의 보호 범위는 아래의 청구범위에 의하여 해석되어야 하며, 그와 동등한 범위 내에 있는 모든 기술 사상은 본 발명의 권리범위에 포함되는 것으로 해석되어야 할 것이다.
