Description

차량용 하이브리드 장치의 윤활 구조{LUBRICATION STRUCTURE OF HYBRID APPARATUS FOR VEHICLE}LUBRICATION STRUCTURE OF HYBRID APPARATUS FOR VEHICLE

본 발명은 윤활 구조에 관한 것으로서, 상세하게는 차량용 하이브리드 장치의 모터 냉각을 위한 윤활 구조에 관한 것이다.The present invention relates to a lubrication structure, and more particularly, to a lubrication structure for cooling a motor of a hybrid device for a vehicle.

일반적으로 하이브리드 차량은 서로 다른 두 종류 이상의 동력원을 효율적으로 조합하여 차량을 구동시키며, 상세하게는 연료(가솔린 등 화석연료)를 연소시켜 회전력을 얻는 엔진과, 배터리 전력으로 회전력을 얻는 모터에 의해 구동하는 차량을 의미한다.In general, a hybrid vehicle drives the vehicle by efficiently combining two or more different types of power sources. Specifically, it is driven by an engine that burns fuel (fossil fuel such as gasoline) to obtain rotational power, and a motor that obtains rotational power using battery power. means a vehicle that

하이브리드 차량은 엔진뿐만 아니라 모터를 보조동력원으로 채택하여 배기가스 저감 및 연비 향상을 도모할 수 있는 미래형 차량으로 현재 연구가 활발히 진행되고 있다.A hybrid vehicle is a future-oriented vehicle that can reduce exhaust gas and improve fuel efficiency by adopting a motor as an auxiliary power source as well as an engine, and research is being actively conducted at present.

이러한 하이브리드 차량은 통상적으로 엔진과 모터를 사용하는데, 저속에서는 상대적으로 저속토크 특성이 좋은 모터를 주 동력원으로 사용하고, 고속에서는 상대적으로 고속토크 특성이 좋은 엔진을 주 동력원으로 사용한다. Such a hybrid vehicle typically uses an engine and a motor. At a low speed, a motor having a relatively good low-speed torque characteristic is used as a main power source, and at a high speed, an engine having a relatively good high-speed torque characteristic is used as a main power source.

이에 따라, 하이브리드 차량은 저속구간에서 화석 연료를 사용하는 엔진의 작동이 정지되고 모터를 사용하기 때문에 연비 개선과 배기가스의 저감에 우수한 효과가 있다.Accordingly, since the hybrid vehicle stops the operation of the engine using the fossil fuel in the low speed section and uses the motor, there is an excellent effect in improving fuel efficiency and reducing exhaust gas.

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.The hybrid vehicle operates in an EV (Electric Vehicle) mode, which is a pure electric vehicle mode that uses only the rotational power of the motor for driving, and an HEV (Hybrid Electric Vehicle) mode that uses the rotational power of the motor as an auxiliary power while using the rotational power of the engine as the main power. mode, and the mode conversion from EV mode to HEV mode is made by starting the engine.

일례로서, 마일드(mild) 하이브리드 장치는 2개 이상의 모터 조합을 통해 단시간동안 풀 하이브리드에 준하는 수준의 출력을 구현할 수 있다. As an example, a mild hybrid device may implement an output comparable to that of a full hybrid for a short time through a combination of two or more motors.

이러한 마일드 하이브리드 장치는 일반적으로 모터의 위치에 따라 P0, P1, P2, P3, P4로 구분하며, 각각은 EV 모드의 구현 여부, 회생 제동 성능 등에 차이를 나타낸다.These mild hybrid devices are generally classified into P0, P1, P2, P3, and P4 according to the position of the motor, and each indicates a difference in whether the EV mode is implemented or not, regenerative braking performance, and the like.

한편, 기존의 마일드 하이브리드 장치 중 P1, P2 모터를 이용하는 하이브리드 장치의 경우 P1, P2 모터를 모두 윤활할 수 있는 윤활 구조는 제시하지 못하고 있다.Meanwhile, in the case of a hybrid device using P1 and P2 motors among existing mild hybrid devices, a lubrication structure capable of lubricating both the P1 and P2 motors has not been proposed.

본 발명은 P1 모터와 P2 모터를 동시에 오일로 윤활할 수 있는 구조를 제공하여, P1 모터와 P2 모터의 성능을 향상시킬 수 있는 하이브리드 장치를 제공하는데 그 목적이 있다.An object of the present invention is to provide a hybrid device capable of improving the performance of the P1 motor and the P2 motor by providing a structure capable of lubricating the P1 motor and the P2 motor with oil at the same time.

또한, 제 2 베어링(80)을 통과한 오일 중 일부는, 제 2 커버(C2)와 P2 로터 샤프트(26) 사이의 공간을 통해 P2 모터(20) 방향으로 이동되어 P2 모터(20)를 냉각 윤활할 수 있다.In addition, some of the oil that has passed through the second bearing 80 moves in the direction of the P2 motor 20 through the space between the second cover C2 and the P2 rotor shaft 26 to cool the P2 motor 20 . can be lubricated.

한편, 제 2 베어링(80)을 통과한 오일 중 일부는, 도 2에 도시된 바와 같이 P1 로터 샤프트(16)와 제 2 커버(C2) 사이의 공간을 통해 P1 모터(10) 방향으로 이동되어 P1 모터(10)를 냉각 윤활할 수 있다.On the other hand, some of the oil that has passed through the second bearing 80 is moved in the direction of the P1 motor 10 through the space between the P1 rotor shaft 16 and the second cover C2 as shown in FIG. The P1 motor 10 may be lubricated by cooling.

전술한 구조에 의해, 엔진 클러치 허브 오일홀(322)을 통과한 오일이 P2 모터(20) 방향으로 이동 가능함과 동시에 P1 모터(10) 방향으로도 일부 이동 가능할 수 있다.With the above-described structure, the oil passing through the engine clutch hub oil hole 322 may move in the direction of the P2 motor 20 and may also partially move in the direction of the P1 motor 10 .

이에 따라 오일을 P1 로터 샤프트 오일홀(162)로 통과시킨 후 제 1 커버(C1)와 P1 로터 샤프트(16) 사이의 공간을 통해 P1 모터(10) 방향으로 이동시켜 P1 모터(10)를 냉각 윤활하는 경로와, 오일을 엔진 클러치 허브 오일홀(322)로 통과시킨 후 통과된 오일 중 일부를 제 2 커버(C2)와 P1 로터 샤프트(16) 사이의 공간을 통해 P1 모터(10) 방향으로 이동시켜 P1 모터(10)를 냉각 윤활하는 경로를 구성할 수 있으므로, P1 모터(10)의 냉각 효율을 더욱 높일 수 있는 효과가 있다.Accordingly, the oil passes through the P1 rotor shaft oil hole 162 and then moves in the direction of the P1 motor 10 through the space between the first cover C1 and the P1 rotor shaft 16 to cool the P1 motor 10 . After passing the oil through the lubrication path and the engine clutch hub oil hole 322, some of the oil passed through the space between the second cover C2 and the P1 rotor shaft 16 in the direction of the P1 motor 10 Since it is possible to configure a path for cooling and lubricating the P1 motor 10 by moving it, there is an effect of further increasing the cooling efficiency of the P1 motor 10 .

또한, 하나의 유로(O)를 통해 오일을 공급하는 윤활 구조에서, 전술한 구성을 통해 P1 모터(10)와 P2 모터(20)를 동시에 냉각하여 P1 모터(10), P2 모터(20)의 수명 및 성능을 향상시킬 수 있다.In addition, in the lubrication structure in which oil is supplied through one flow path O, the P1 motor 10 and the P2 motor 20 are simultaneously cooled through the above-described configuration to form the P1 motor 10 and the P2 motor 20. Lifespan and performance can be improved.

한편, P2 로터 샤프트(26)와 엔진 클러치 허브(32) 사이에는 축방향에 대해 제 2 실링부재(S2)가 구비될 수 있다.Meanwhile, a second sealing member S2 may be provided between the P2 rotor shaft 26 and the engine clutch hub 32 in the axial direction.

일례로서, 제 2 실링부재(S2)는 엔진 클러치 허브 오일홀(322)을 통과한 오일이 외부로 누출되지 않도록 P2 로터 샤프트(26)와 엔진 클러치 허브(32) 사이의 공간을 밀폐할 수 있고, 오일 씰의 일종일 수 있다.As an example, the second sealing member S2 may seal the space between the P2 rotor shaft 26 and the engine clutch hub 32 so that the oil that has passed through the engine clutch hub oil hole 322 does not leak to the outside. , can be some kind of oil seal.
