Description

클러치 모듈{CLUTCH MODULE}Clutch Module {CLUTCH MODULE}

본 고안은 하나의 공통 하우징 내에 하나 이상의 클러치와, 이 클러치의 유압 작동을 위한 하나의 작동 부재를 포함하는 클러치 모듈에 관한 것이다.The present invention relates to a clutch module comprising one or more clutches in one common housing and one actuating member for hydraulic actuation of the clutches.

종래 기술, 예컨대 DE1020070124971 A1호로부터는 유압 작동식 다판 클러치들이 공지되어 있다. 클러치들은 클러치 외부 부재와; 클러치 내부 부재와; 클러치 내부 부재 및 클러치 외부 부재와 교호적으로 함께 회전하는 방식으로 연결되는 디스크들로 구성되는 다판 패키지(multi-disc package)와; 변위 가능하게 장착되어 다판 패키지에 작용하는 압력 피스톤을; 포함하며, 다판 패키지의 반대 방향으로 향해 있는 압력 피스톤의 측에는 압력 발생기를 통해 압력 유체(pressure fluid)를 공급받을 수 있는 작동 챔버(working chamber)가 형성된다.Hydraulic actuated multi-plate clutches are known from the prior art, for example DE1020070124971 Al. The clutches comprise a clutch outer member; A clutch inner member; A multi-disc package comprising discs connected in a rotating manner in an alternating manner with the clutch inner member and the clutch outer member; A pressure piston mounted displaceably on the multi-plate package; And a working chamber is formed on the side of the pressure piston facing in the opposite direction of the multi-plate package, through which pressure fluid can be supplied through the pressure generator.

상기 유형의 클러치들은 예컨대 자동차의 파워 트레인 내에서, 변속기 클러치들로서, 또는 연결 가능한 동력 전달이 제어되어야 하는 기타 적용 분야들에서 이용된다. 상기 유형의 클러치들이 자동차의 파워 트레인 내에서 주행 다이내믹 제어장치의 명령하에 하나의 액슬의 2개의 휠에, 또는 2개의 피동 액슬(driven axle)에 구동 토크의 분배를 제어하기 위해 이용된다면, 전체 유효 수명에 걸쳐 높은 정밀도 및 우수한 동적 거동이 필요하다. 작동압을 생성하기 위해, 다판 클러치를 위한 작동압의 생성을 위해 작동 부재들로서 상이한 구동 장치들을 포함하는 유압 펌프들이 이용된다. 이 경우, 작동 유체는 라인들을 통해 하우징의 외부에 설치되어 있는 작동 챔버 내로 공급된다. 그 외에, 클러치의 하우징 내부에 있는 연결 보어들을 통해 유체가 공급되는 점도 공지되어 있다. 점점 더 협소해지는 장착 공간을 통해, 클러치 및 작동 부재는 구조적으로 밀집되게 함께 장착되어야 한다. 예컨대 차량의 뒷차축 상의 장착 위치는 탱크 및 액슬 지지대를 통해 매우 제한된다. 클러치들은 뒷차축으로 구동 토크의 전달을 위해 표준 전륜 구동 자동차의 뒷차축 상에 장착된다. 그러나 이와 동시에 높은 통합 정도로 인해, 서로 얽혀 있는 컴포넌트들의 조립은 더욱더 어려워진다.Clutches of this type are used, for example, in powertrain of an automobile, as transmission clutches, or in other applications where connectable power transmission must be controlled. If the clutches of this type are used to control the distribution of the drive torque to two wheels of one axle or two driven axles under the command of the traveling dynamic control device in the powertrain of the vehicle, High precision and good dynamic behavior over the life span is required. To generate the operating pressure, hydraulic pumps are used which include different driving devices as actuating members for generation of operating pressure for the multi-plate clutch. In this case, the working fluid is supplied through the lines into an operating chamber provided outside the housing. In addition, it is known that fluid is supplied through connecting bores within the housing of the clutch. Through the mounting space becoming increasingly narrow, the clutch and actuating member must be mounted together in a structurally dense manner. For example, the mounting position on the rear axle of the vehicle is very limited through the tank and axle supports. The clutches are mounted on the rear axle of a standard front-wheel drive vehicle for transmission of drive torque to the rear axle. At the same time, however, due to the high degree of integration, the assembly of intertwined components becomes more difficult.

본 고안의 과제는 간단한 조립이 보장되면서 클러치 및 작동 부재를 구조적으로 통합하는 클러치 모듈을 제안하는 것에 있다.The object of the present invention is to propose a clutch module which structurally integrates the clutch and the operating member while ensuring simple assembly.

상기 과제는, 하나의 공통 하우징 내에 하나 이상의 클러치와, 이 클러치의 유압 작동을 위한 하나의 작동 부재를 포함하는 클러치 모듈로 해결된다.This object is solved by a clutch module comprising at least one clutch in one common housing and one actuating member for hydraulic actuation of the clutch.

따라서, 클러치 모듈을 위한 작은 장착 공간에 대해 최적의 매칭이 가능하다.Thus, optimal matching is possible for a small mounting space for the clutch module.

이 경우, 클러치 모듈은, 바람직하게 작동 부재를 위한 제1 하우징 부재가 제1 축을 따라 배치되고 제2 하우징 부재가 클러치를 포함하여 제2 축을 따라 배치되도록 구성된다.In this case, the clutch module is preferably configured such that the first housing member for the actuating member is disposed along the first axis and the second housing member is disposed along the second axis including the clutch.

바람직하게, 작동 부재는 축을 따라서 펌프와, 전기 모터와, 제어 유닛을 포함하며, 펌프 및 전기 모터는 구조적으로 서로 분리된다.Preferably, the actuating member comprises a pump along the axis, an electric motor and a control unit, wherein the pump and the electric motor are structurally separate from one another.

작동 부재의 장착 유형을 통해, 하우징 내의 연결 보어는 클러치에서 작동 챔버의 압력 챔버와 펌프의 압력 영역의 연결부로서 직접 연장된다. 이러한 직접적인 연결은 유압 시스템을 위한 최선의 연결이면서 클러치 모듈의 조립을 간소화시킨다.Through the mounting type of the actuating member, the connecting bore in the housing extends directly from the clutch as a connection between the pressure chamber of the operating chamber and the pressure region of the pump. This direct connection is the best connection for the hydraulic system and simplifies the assembly of the clutch module.

본 고안은 하기에서 첨부한 도면을 참조하여 예시로서 기재된다.The present invention will now be described by way of example with reference to the accompanying drawings, in which: Fig.

도 1 및 도 2는 클러치 모듈을 개략적으로 도시한 도면이다.Figures 1 and 2 schematically show a clutch module.

도 1에는, 하나의 시점에서 클러치 모듈(50)을 도시한 도면이 도시되어 있다. 클러치 모듈(50)은, 두 메인 컴포넌트인, 하나의 클러치(6) 및 하나의 작동 부재(1)를 에워싸는 하우징(17)을 포함한다. 두 메인 컴포넌트는 공통 하우징(17) 내에 수용된다. 이 경우, 하우징(17)은 다중 부재형으로 형성되며, 적어도 하우징은, 하우징(17)의 내부 장착 공간에 접근하게 하여 하우징(17) 내에 개별 컴포넌트들을 조립하도록 하기 위해 이용되는 하우징 커버들(17C 및 17D)을 포함한다.FIG. 1 shows a view of the clutch module 50 at one time. The clutch module 50 includes a housing 17 enclosing one clutch 6 and one operating member 1, which are two main components. The two main components are housed in a common housing (17). In this case, the housing 17 is formed in a multi-member shape, and at least the housing includes housing covers 17C, 17C used to allow the individual components to be assembled in the housing 17 by accessing the internal mounting space of the housing 17. [ And 17D.

클러치 모듈(50)은, 이 클러치 모듈(50)을 함께 회전하는 방식으로 샤프트, 즉 카르단 샤프트(Cardan shaft) 상에 결합시키는 플랜지(19)를 포함한다. 작동 부재(1)는, 클러치(6)의 제2 하우징 부재(17B)에 밀봉 결합되는 하우징 부재(17A) 내에 위치된다. 그 외에 도 1에서는, 수직선에서 하우징(17B)에 대해 경사지게 조립되어 있는 작동 부재(1)용 커넥터(21) 역시도 제공되어 있는 점을 확인할 수 있다. 또한, 도 1에는, 작동 부재(1)의 제1 하우징 부재(17A)가 최대한 공간을 절약하면서 클러치의 제2 하우징 부재(17B) 상에서 연장되는 점도 도시되어 있다.The clutch module 50 includes a flange 19 that engages the clutch module 50 on a shaft, i.e., a Cardan shaft, in a rotating manner. The operating member 1 is located in the housing member 17A which is hermetically sealed to the second housing member 17B of the clutch 6. In addition, in FIG. 1, it can be seen that the connector 21 for the actuating member 1, which is assembled inclined with respect to the housing 17B on the vertical line, is also provided. 1 also shows that the first housing member 17A of the actuating member 1 extends over the second housing member 17B of the clutch while saving as much space as possible.

도 2에는, 클러치 모듈의 샤프트 축(A)을 따르는 단면이 도시되어 있다. 여기서는, 작동 부재(1)가 자신의 구성과 관련하여 확인된다. 작동 부재(1)는 전기 모터(3)와 펌프(4)를 포함한다. 전기 모터(3)는, 펌프 샤프트(23)를 구동하는 모터 샤프트(22) 상에 안착된다. 전기 모터(3)로부터 펌프(4)로 향하는 동력은, 일 실시형태에서, 모터 샤프트(22)로부터 펌프(4) 상으로 직접 전달되며, 펌프 샤프트(23)는 모터 샤프트(22)의 연장부이다.Fig. 2 shows a cross section along the shaft axis A of the clutch module. Here, the operation member 1 is identified with respect to its configuration. The operation member 1 includes an electric motor 3 and a pump 4. The electric motor 3 is seated on the motor shaft 22 that drives the pump shaft 23. The power from the electric motor 3 to the pump 4 is delivered directly from the motor shaft 22 onto the pump 4 in one embodiment and the pump shaft 23 is connected to the extension of the motor shaft 22 to be.

펌프(4)는 기어 펌프 또는 피스톤 펌프로서 구현되어 전기 모터(3)의 모터 샤프트(22)의 연장부 내에서 제어 유닛(2) 상에 부착된다. 여기서 중요한 점은, 전기 모터(3) 및 펌프(4)가 서로 분리된 컴포넌트들로서 구성됨으로써 컴포넌트들은 개별적으로 그 접근성이 양호하고 펌프는 클러치와 최적으로 연결될 수 있다는 점이다. The pump 4 is implemented as a gear pump or a piston pump and is mounted on the control unit 2 within the extension of the motor shaft 22 of the electric motor 3. It is important here that the electric motor 3 and the pump 4 are constructed as components separated from each other so that the components are individually accessible and the pump can be optimally connected to the clutch.

펌프(4)는, 하우징 부재(17A) 내에 설치되고 하우징 커버(17C)로 폐쇄되어, 클러치를 작동시키기 위해, 유체 내 원하는 압력을 형성할 수 있다. 유체는 연결 보어(5)를 통해 안내되고, 펌프(4) 내의 연결 보어(5)는 압력 챔버 내에서 공통 하우징(17) 내 관통 개구부로서 존재하며 클러치의 작동 챔버(18)까지 이어진다. 연결 보어는 클러치의 하우징 내에서 직선으로 연장된다. 따라서 연결 보어는 단순한 유형 및 방식으로 제조될 수 있으며, 클러치 모듈을 위해 별도의 연결 라인을 배치하지 않아도 될뿐더러 하우징의 복잡한 구성도 실현하지 않아도 된다. 가압된 유체는 연결 보어(5)를 통해 작동 챔버(18) 내로 공급되어 유압 피스톤(8)을 가압한다.The pump 4 may be installed in the housing member 17A and closed with a housing cover 17C to form the desired pressure in the fluid to actuate the clutch. The fluid is guided through the connecting bore 5 and the connecting bore 5 in the pump 4 exists as a through opening in the common housing 17 in the pressure chamber and extends to the operating chamber 18 of the clutch. The connecting bore extends straight in the housing of the clutch. Therefore, the connecting bore can be manufactured in a simple type and manner, and it is not necessary to dispose a separate connecting line for the clutch module and to realize a complicated configuration of the housing. The pressurized fluid is supplied into the operation chamber 18 through the connecting bore 5 to pressurize the hydraulic piston 8.

다판 클러치는, 클러치 외부 부재가 함께 회전하는 방식으로 연결되는 일차 샤프트를 포함한다. 또한, 클러치 내부 부재와 함께 회전하는 방식으로 연결된 이차 샤프트도 제공된다. 샤프트들은 도면에 도시되어 있지 않다. 클러치 외부 부재와 클러치 내부 부재 사이에는, 공지된 방식으로 클러치 외부 부재 및 클러치 내부 부재와 교호적으로 함께 회전하는 방식으로 연결된 디스크들로 구성되는 다판 패키지(16)가 배치된다. 다판 패키지(16)로부터 이격되어서는 유압 피스톤(8)이 배치되며, 이 유압 피스톤을 통해서는 다판 패키지(16)가 받침부로서의 클러치 내부 부재에 의해 압축 스프링들의 힘에 대항하여 압축될 수 있다. 원칙상, 다판 클러치의 릴리즈가 또 다른 방식으로, 예컨대 유압 피스톤(8)의 수동적 또는 능동적 복귀를 통해 보장된다면, 압축 스프링들은 생략될 수도 있다. 또한, 하우징(17) 내에는, 연결 라인을 통해 압력 유체를 공급받을 수 있는 작동 챔버(18)도 형성된다. 이 경우, 작동 챔버(18)는 환형으로, 또는 예컨대 원통형으로도 형성될 수 있다.The multi-plate clutch includes a primary shaft to which the clutch outer member is connected in a rotating manner. Also provided is a secondary shaft connected in a rotatable manner with the clutch inner member. Shafts are not shown in the drawings. Between the clutch outer member and the clutch inner member, there is disposed a multi-plate package 16 consisting of discs connected in a rotatable manner in an alternating manner with the clutch outer member and the clutch inner member in a known manner. A hydraulic piston 8 is disposed apart from the multi-plate package 16 through which the multi-plate package 16 can be compressed against the forces of the compression springs by the clutch inner member as a bearing. In principle, the compression springs may be omitted if the release of the multi-plate clutch is ensured in another way, for example by a passive or active return of the hydraulic piston 8. Also, in the housing 17, an operation chamber 18 is formed which is capable of receiving pressure fluid through the connection line. In this case, the operation chamber 18 may be formed in an annular shape, or even in a cylindrical shape.
