Description

하이브리드 변속기 장치{HYBRID TRANSMISSION APPARATUS}Hybrid transmission device {HYBRID TRANSMISSION APPARATUS}

본 발명은 전기모터와 두개의 유압 제어 클러치로 구성되는 하이브리드 변속기 장치에 관한 것이다.The present invention relates to a hybrid transmission device comprising an electric motor and two hydraulic control clutches.

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.In general, a hybrid vehicle means driving a vehicle by efficiently combining two or more different types of power sources. A hybrid vehicle refers to a vehicle driven by an engine that obtains torque by burning fuel (fossil fuel such as gasoline) and a motor that obtains torque by battery power.

이러한 하이브리드 차량은 엔진뿐만 아니라 모터를 보조동력원으로 채택하여 배기가스 저감 및 연비 향상을 도모할 수 있는 미래형 차량으로 연구가 활발히 진행되고 있다.These hybrid vehicles are being actively researched as future vehicles that can reduce exhaust gas and improve fuel efficiency by adopting a motor as well as an engine as an auxiliary power source.

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.A hybrid vehicle typically uses an engine and a motor. At low speeds, a motor with relatively good low-speed torque characteristics is used as a main power source, and at high speeds, an engine with relatively good high-speed torque characteristics is used as a main power source. Accordingly, in the hybrid vehicle, since the operation of the engine using fossil fuel is stopped and the motor is used in the low speed range, there is an excellent effect in improving fuel efficiency and reducing exhaust gas.

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.Drive devices for hybrid vehicles include EV (Electric Vehicle) mode, which is a pure electric vehicle mode that uses only the torque of the motor for driving, and HEV (Hybrid Electric Vehicle) mode, which uses the torque of the motor as auxiliary power while using the torque of the engine as the main power. driving in the driving mode, and mode conversion from EV mode to HEV mode is performed by starting the engine.

종래의 하이브리드용 변속기 장치는 모터의 개수, 위치에 따라 P1, P2, P3, P4 등으로 나뉘며, P1, P2, P3, P4 등의 조합도 가능하다. 또한, 종래의 하이브리드용 변속기 장치는 P1, P2, P3, P4 등의 각 장치별 부착되는 관련 부품의 조합도 다양하다.Conventional hybrid transmission devices are divided into P1, P2, P3, P4, etc. according to the number and position of motors, and a combination of P1, P2, P3, P4, etc. is also possible. In addition, the conventional hybrid transmission device has various combinations of related parts attached to each device such as P1, P2, P3, and P4.

도 1은 종래의 하이브리드 변속기 장치를 개략적으로 나타내는 도면이다. 도 1을 참조하면, 종래의 하이브리드 변속기 장치는 엔진의 스타터 모터를 삭제하고 P2 모터와 K0 클러치를 이용하여 엔진을 시동시키는 구조이다.1 is a diagram schematically illustrating a conventional hybrid transmission device. Referring to FIG. 1, the conventional hybrid transmission has a structure in which the starter motor of the engine is deleted and the engine is started using a P2 motor and a K0 clutch.

구체적으로 종래의 하이브리드 변속기 장치는 고전압 배터리(110), 고전압 배터리(110)로부터 전원을 공급 받아 작동하는 전동식 오일펌프(120), 고전압 배터리(110)로부터 전원을 공급 받아 동력을 발생하는 P2 모터(130), 변속기(140), 엔진(150), P2 모터(130)와 엔진(150)을 연결 또는 해제하는 K0 클러치(161) 및 P2 모터(130)와 변속기(140)를 연결 또는 해제하는 K1 클러치(162)를 포함한다.Specifically, the conventional hybrid transmission device includes a high voltage battery 110, an electric oil pump 120 operated by receiving power from the high voltage battery 110, and a P2 motor generating power by receiving power from the high voltage battery 110 ( 130), transmission 140, engine 150, K0 that connects or disconnects P2 motor 130 and engine 150 Clutch 161 and K1 that connects or disconnects P2 motor 130 and transmission 140 Clutch 162 is included.

그런데 종래의 하이브리드 변속기 장치는 차량 주행 중 고전압 배터리가 고장나면, 엔진, P2 모터, 변속기를 연결하는 모든 클러치의 유압생성이 해제되어 차량 주행이 불가능하였다.However, in the conventional hybrid transmission device, when the high-voltage battery fails while the vehicle is driving, hydraulic pressure generation of all clutches connecting the engine, the P2 motor, and the transmission is released, making it impossible to drive the vehicle.

이에 대하여, 본 발명은 차량 주행 중 배터리의 고장으로 P2 모터와 전동식 오일펌프의 전원이 차단되었을 때에도 원웨이 클러치의 작동으로 지속적인 차량 주행이 가능한 메커니즘을 제시하고자 한다.In contrast, the present invention is intended to provide a mechanism capable of continuously driving a vehicle by operating a one-way clutch even when power to the P2 motor and the electric oil pump is cut off due to a battery failure during vehicle driving.

The present invention can provide a mechanism optimized for the layout of the transmission unit of the P2 hybrid vehicle transmission. Engine starting according to the present invention may be performed by a motor and a first clutch.

구체적으로 본 발명은 배터리(210) 고장이 발생하여 유압 공급이 차단될 경우 원웨이 클러치(270)의 작동을 통하여 엔진(250)의 동력을 모터(230)에 전달한다. 일예로서 모터(230)는 하우징(291) 내부에 장착되는 P2 모터일 수 있다.Specifically, the present invention transmits the power of the engine 250 to the motor 230 through the operation of the one-way clutch 270 when the battery 210 fails and the hydraulic supply is cut off. As an example, the motor 230 may be a P2 motor mounted inside the housing 291 .

엔진(250)의 동력을 모터(230)에 전달시 모터(230)는 발전모드로 전환되어 발전이 가능한 제네레이터(generator)가 된다. 모터(230)에서 생성된 전력으로 오일펌프(220)를 구동시켜 클러치를 제어할 수 있다. 클러치는 제1 클러치(261) 및 제2 클러치(262)를 포함한다.When the power of the engine 250 is transmitted to the motor 230, the motor 230 is converted to a power generation mode and becomes a generator capable of generating power. The clutch may be controlled by driving the oil pump 220 with electric power generated by the motor 230 . The clutch includes a first clutch 261 and a second clutch 262 .

모터(230)는 스테이터(231), 로터(232) 및 로터 슬리브(233)를 포함한다. 로터 슬리브(233)에 마련된 내측 공간(233a)에 클러치 및 원웨이 클러치(270)가 구비된다.The motor 230 includes a stator 231, a rotor 232 and a rotor sleeve 233. A clutch and a one-way clutch 270 are provided in the inner space 233a provided in the rotor sleeve 233.

일예로서 제1 클러치(261)는 K0 클러치일 수 있다. 제1 클러치(261)의 일측에는 댐퍼(292)가 구비될 수 있다. 제1 클러치(261)는 로터 슬리브(233)의 내측 공간(233a)에서 제2 클러치(262)보다 엔진(250)에 더 근접하도록 구성된다. 제1 클러치(261)는 로터 슬리브(233)의 내측 공간(233a)에서 엔진(250) 쪽을 향하도록 위치한다.As an example, the first clutch 261 may be a K0 clutch. A damper 292 may be provided on one side of the first clutch 261 . The first clutch 261 is configured to be closer to the engine 250 than the second clutch 262 in the inner space 233a of the rotor sleeve 233 . The first clutch 261 is positioned toward the engine 250 in the inner space 233a of the rotor sleeve 233.

제1 클러치(261)는 다판클러치(multi-plate clutch)로 구성된다. 다판클러치(261a)의 작동에 의해 로터 슬리브(233)와 제1 인풋샤프트(281)가 연결되면 동력을 변속기(240)로 전달할 수 있다. 반대로 다판클러치(261a)에 의해 로터 슬리브(233)와 제1 인풋샤프트(281)의 연결이 해제되면 변속기(240)로 동력 전달이 차단된다.The first clutch 261 is configured as a multi-plate clutch. When the rotor sleeve 233 and the first input shaft 281 are connected by the operation of the multi-plate clutch 261a, power may be transmitted to the transmission 240. Conversely, when the connection between the rotor sleeve 233 and the first input shaft 281 is released by the multi-plate clutch 261a, power transmission to the transmission 240 is blocked.

일예로서 제2 클러치(262)는 K1 클러치일 수 있다. 제2 클러치(262)는 로터 슬리브(233)의 내측 공간(233a)에서 제1 클러치(261)에 대향하도록 제1 클러치(261)의 일측에 구비된다. 제2 클러치(262)는 로터 슬리브(233)의 내측 공간(233a)에서 제1 클러치(261)보다 변속기(240) 쪽에 더 근접하도록 구성된다. 제2 클러치(262)는 로터 슬리브(233)의 내측 공간(233a)에서 변속기(240) 쪽을 향하도록 위치한다.As an example, the second clutch 262 may be a K1 clutch. The second clutch 262 is provided on one side of the first clutch 261 to face the first clutch 261 in the inner space 233a of the rotor sleeve 233 . The second clutch 262 is configured to be closer to the transmission 240 than the first clutch 261 in the inner space 233a of the rotor sleeve 233. The second clutch 262 is positioned toward the transmission 240 in the inner space 233a of the rotor sleeve 233.

제2 클러치(262)는 다판클러치(multi-plate clutch)로 구성된다. 다판클러치(262a)의 작동에 의해 로터 슬리브(233)와 제2 인풋샤프트(282)가 연결되면 엔진(250)에서 발생된 동력을 로터(232)로 전달할 수 있다. 반대로 다판클러치(262a)에 의해 로터 슬리브(233)와 제2 인풋샤프트(282)의 연결이 해제되면 로터(232)로 동력 전달이 차단된다.The second clutch 262 is configured as a multi-plate clutch. When the rotor sleeve 233 and the second input shaft 282 are connected by the operation of the multi-plate clutch 262a, power generated in the engine 250 may be transmitted to the rotor 232. Conversely, when the connection between the rotor sleeve 233 and the second input shaft 282 is released by the multi-plate clutch 262a, power transmission to the rotor 232 is blocked.

한편, 원웨이 클러치(270)는 로터 슬리브(233)와 제1 인풋샤프트(281) 사이에 위치한다. 원웨이 클러치(270)는 배터리(210) 고장시 제1 인풋샤프트(281)와 로터 슬리브(233)를 연결한다. 제1 인풋샤프트(281)와 로터 슬리브(233)가 연결됨에 따라 엔진(250)의 동력을 모터(230)로 전달할 수 있다. 이때 모터(230)는 발전이 가능한 제네레이터가 된다. 모터(230)의 발전을 통해 생성된 전력으로 전동식 오일펌프(220)를 구동시켜 클러치를 제어함으로써 차량 주행이 가능하게 할 수 있다.Meanwhile, the one-way clutch 270 is located between the rotor sleeve 233 and the first input shaft 281. The one-way clutch 270 connects the first input shaft 281 and the rotor sleeve 233 when the battery 210 fails. As the first input shaft 281 and the rotor sleeve 233 are connected, power of the engine 250 may be transmitted to the motor 230 . At this time, the motor 230 becomes a generator capable of generating electricity. The driving of the vehicle can be made possible by controlling the clutch by driving the electric oil pump 220 with electric power generated through the power generation of the motor 230 .

일예로서, 원웨이 클러치(270)는 "엔진 회전수 > 로터 회전수 또는 엔진 회전수 = 로터 회전수"와 같은 조건에서 로크(LOCK)되어 동력이 전달이 이루어지게 한다.As an example, the one-way clutch 270 is locked under a condition such as “engine speed > rotor speed or engine speed = rotor speed” to transmit power.

일예로서, 웬웨이 클러치(270)는 "엔진 회전수 < 로터 회전수"와 같은 조건에서 동력 연결을 해제(프리휠, freewheel)한다.As an example, the where-way clutch 270 disconnects power (freewheel) under a condition such as “engine speed < rotor speed”.

이와 같이 본 발명은 배터리 고장시 웬웨이 클러치를 통해 종래의 배터리 고장시 발생하는 문제를 해결할 수 있다. 구체적으로 종래의 하이브리 변속기 장치는 차량 주행 중 배터리 고장이 발생하면 엔진, 모터, 변속기를 연결하는 모든 클러치의 유압생성이 해제되어 차량 주행이 불가능하였다. 그러나 본 발명은 차량 주행 중 배터리 고장으로 모터와 오일펌프의 전원이 차단되더라도 원웨이 클러치의 작동으로 지속적인 차량 주행이 가능함에 따라 종래와 같이 배터리 고장으로 고속도로나 교통량이 많은 지역에서 차량 주행 정지로 인한 교통사고 유발의 위험으로부터 차량 탑승자를 보호할 수 있다.As described above, the present invention can solve the problem that occurs when a battery fails in the related art through the where-way clutch when the battery fails. Specifically, in the conventional hybrid transmission device, when a battery failure occurs while the vehicle is driving, hydraulic pressure generation of all clutches connecting the engine, motor, and transmission is released, making it impossible to drive the vehicle. However, according to the present invention, even if the power of the motor and the oil pump is cut off due to a battery failure while the vehicle is running, the vehicle can be continuously driven by the operation of the one-way clutch. Vehicle occupants can be protected from the risk of causing a traffic accident.

In addition, the present invention can switch the P2 motor to the power generation mode when there is power from the engine. In addition, the present invention drives the electric oil pump with the power generated through the power generation of the P2 motor, so that the vehicle can be driven through clutch control. In addition, the present invention can expect cost reduction and mountability improvement by using a one-way clutch as a separate power source in case of battery failure.
