Description

하이브리드 차량용 시동장치{Starter for Hybrid Electric Vehicle} Starter for Hybrid Electric Vehicle}

본 발명은 하이브리드 차량용 시동장치에 관한 것으로서, 보다 상세하게는 TMED(Transmission Mounted Eletric Device) 방식의 병렬형 하이브리드 차량의 변속기 케이스 상에 12V 스타트 모터를 직접 장착하여 엔진룸 패키지를 개선하고, 원가 절감 및 중량이 저감된 하이브리드 시스템을 개발할 수 있도록 하는 하이브리드 차량용 시동장치에 관한 것이다.The present invention relates to a starting device for a hybrid vehicle, and more specifically, to improve the engine room package, reduce costs, and improve the engine room package by directly mounting a 12V start motor on the transmission case of a TMED (Transmission Mounted Eletric Device) type parallel hybrid vehicle. This relates to a starting device for a hybrid vehicle that enables the development of a hybrid system with reduced weight.

차량에 있어서의 친환경 기술은 미래 자동차 산업의 생존이 달린 핵심 기술로서, 자동차 메이커들은 환경 및 연비 규제를 달성하기 위한 친환경 자동차 개발에 총력을 기울이고 있다.Eco-friendly technology in vehicles is a key technology on which the survival of the future automobile industry depends, and automakers are putting all their efforts into developing eco-friendly vehicles to meet environmental and fuel efficiency regulations.

이에 따라 각 자동차 메이커들은 전기 자동차(EV : Electric Vehicle), 하이브리드 전기 자동차(HEV : Hybrid Electric Vehicle), 연료전지 자동차(FCEV : Fuel Cell Electric Vehicle)등을 미래형 자동차 기술로서 개발하고 있다.Accordingly, each automobile manufacturer is developing electric vehicles (EV: Electric Vehicle), hybrid electric vehicles (HEV: Hybrid Electric Vehicle), and fuel cell electric vehicles (FCEV: Fuel Cell Electric Vehicle) as future automobile technologies.

상기와 같은 미래형 자동차는 중량 및 원가 등 여러 가지 기술적인 제약이 있기 때문에 자동차 메이커에서는 배기가스 규제를 만족시키고, 연비 성능의 향상을 위한 현실적인 문제의 대안으로서 하이브리드 전기자동차에 주목하고 있으며, 이를 실용화하기 위해 치열한 경쟁을 벌이고 있다.Since the above-mentioned future cars have various technical limitations such as weight and cost, car manufacturers are paying attention to hybrid electric vehicles as an alternative to practical problems to satisfy exhaust gas regulations and improve fuel efficiency, and to put them into practical use. There is fierce competition for

즉, 하이브리드 전기 자동차는 2개 이상의 동력원(Power Source)을 사용하는 자동차로서, 여러 가지 방식으로 조합될 수 있으며, 동력원으로는 기존의 화석 연료를 사용하는 가솔린 엔진 또는 디젤 엔진과 전기 에너지에 의하여 구동되는 모터/제너레이터가 혼합되어 사용된다.In other words, a hybrid electric vehicle is a vehicle that uses two or more power sources and can be combined in various ways. The power source is a gasoline or diesel engine using existing fossil fuels and is driven by electrical energy. A mixture of motors/generators is used.

이러한 하이브리드 전기 자동차는 저속에서 상대적으로 저속토크 특성이 좋은 모터/제너레이터를 주 동력원으로 사용하고, 고속에서는 상대적으로 고속토크 특성이 좋은 엔진을 주 동력원으로 사용한다.These hybrid electric vehicles use a motor/generator with relatively good low-speed torque characteristics as the main power source at low speeds, and use an engine with relatively good high-speed torque characteristics as the main power source at high speeds.

이에 따라 하이브리드 전기 자동차는 저속구간에서 화석 연료를 사용하는 엔진의 작동이 정지되고 모터/제너레이터를 사용하기 때문에 연비 개선과 배기가스의 저감에 우수한 효과가 있다.Accordingly, hybrid electric vehicles have excellent effects in improving fuel efficiency and reducing exhaust gases because the engine using fossil fuels stops operating at low speeds and a motor/generator is used.

상기에서 본 발명과 관련되는 TMED(Transmission Mounted Eletric Device) 방식의 병렬형 하이브리드 전기자동차는 48V의 고전압 파워를 사용하는 HSG(Hybrid Starter Generator)가 적용된다.As described above, the TMED (Transmission Mounted Electric Device) type parallel hybrid electric vehicle related to the present invention is equipped with a HSG (Hybrid Starter Generator) that uses high voltage power of 48V.

그러나 기존의 병렬형 하이브리드 전기 자동차에 적용되는 HSG는 풀리 벨트 방식으로 엔진과의 상시 벨트 체결 조건 때문에 엔진 구동 이후에도 여타 기능을 수행하지 않음에도 적은 양이지만 엔진 측에서는 부하로 간주되어 연비 효율을 저하시키게 되는 문제점이 있다.However, the HSG applied to the existing parallel hybrid electric vehicle is a pulley belt type and does not perform any other functions even after the engine is driven due to the condition of constant belt fastening to the engine. Although it is a small amount, it is considered a load on the engine side and reduces fuel efficiency. There is a problem.

또한, 기존의 HSG는 주변 부품인 풀리, 벨트, 텐셔너, 아이들러 및 HSG를 위한 고전압용 케이블 등이 엔진의 일측에 구비되어 엔진룸 패키지에 불리하고, 원가 및 중량의 측면에서도 불리한 문제점이 있다. In addition, the existing HSG has peripheral components such as pulleys, belts, tensioners, idlers, and high-voltage cables for the HSG, which are provided on one side of the engine, which is disadvantageous to the engine room package and has disadvantages in terms of cost and weight.

이 배경기술 부분에 기재된 사항은 발명의 배경에 대한 이해를 증진하기 위하여 작성된 것으로서, 이 기술이 속하는 분야에서 통상의 지식을 가진 자에게 이미 알려진 종래기술이 아닌 사항을 포함할 수 있다.The matters described in this background art section have been prepared to enhance understanding of the background of the invention, and may include matters that are not prior art already known to those skilled in the art in the field to which this technology belongs.

본 발명의 실시 예는 TMED(Transmission Mounted Eletric Device) 방식의 병렬형 하이브리드 차량의 변속기 케이스 상에 직접 12V 스타트 모터를 장착하여 기존의 풀리 방식의 HSG(Hybrid Starter Generator) 및 주변 부품을 삭제할 수 있으며, 이로 인해 엔진룸 패키지를 개선하고, 원가 절감 및 중량이 저감된 하이브리드 시스템을 개발할 수 있도록 하는 하이브리드 차량용 시동장치를 제공하고자 한다.An embodiment of the present invention can eliminate the existing pulley-type HSG (Hybrid Starter Generator) and surrounding parts by mounting a 12V start motor directly on the transmission case of a TMED (Transmission Mounted Eletric Device) type parallel hybrid vehicle. As a result, we aim to provide a starting device for hybrid vehicles that improves the engine room package and develops a hybrid system with reduced costs and weight.

또한, 상기 하이브리드 차량용 시동장치는 상기 스타트 모터의 회전축과 상기 프론트 하우징 사이에 개재되는 베어링을 더 포함할 수 있다.Additionally, the starting device for a hybrid vehicle may further include a bearing interposed between the rotating shaft of the starting motor and the front housing.

또한, 상기 프론트 하우징은 상기 스타트 모터의 회전축 선단에 대응하여 상기 부시가 압입되어 고정되는 부시 압입홀이 형성될 수 있다.Additionally, the front housing may be formed with a bush press-fit hole into which the bush is press-fitted and fixed in response to the tip of the rotation axis of the start motor.

또한, 상기 프론트 하우징은 상기 부시 압입홀에 이웃하여 외측에 상기 베어링이 압입되는 베어링 압입홀이 단차지게 형성될 수 있다.Additionally, the front housing may have a stepped bearing press-fit hole into which the bearing is press-fitted on the outside adjacent to the bush press-fit hole.

또한, 상기 프론트 하우징은 상기 베어링 압입홀에 이웃하여 외측에 상기 스타트 모터의 스타트 기어가 작동하는 기어 작동홀이 단차지게 형성될 수 있다.Additionally, the front housing may be adjacent to the bearing press-fit hole and have a stepped gear operation hole on the outside where the start gear of the start motor operates.

또한, 상기 부시는 메탈 부시로 이루어질 수 있다.Additionally, the bush may be made of a metal bush.

또한, 상기 회전축은 상기 부시에 삽입되는 선단이 테이퍼 가공될 수 있다.Additionally, the tip of the rotating shaft inserted into the bush may be tapered.

또한, 상기 하이브리드 차량용 시동장치는 상기 프론트 하우징에 대응하여 상기 변속기 케이스와 상기 모터 커버 사이에 케이블 연결을 위한 케이블 소켓 하우징이 일체로 형성될 수 있다.Additionally, the starting device for a hybrid vehicle may have a cable socket housing for connecting a cable between the transmission case and the motor cover integrally formed with the front housing.

본 발명의 실시 예는 TMED(Transmission Mounted Eletric Device) 방식의 병렬형 하이브리드 차량의 변속기 케이스 상에 직접 12V 스타트 모터를 장착하여 기존의 풀리 방식의 48V의 HSG(Hybrid Starter Generator) 및 주변 부품인 풀리, 벨트, 텐셔너, 아이들러 및 HSG를 위한 고전압용 케이블 등을 삭제할 수 있다. In an embodiment of the present invention, a 12V start motor is mounted directly on the transmission case of a TMED (Transmission Mounted Eletric Device) type parallel hybrid vehicle, and a 48V HSG (Hybrid Starter Generator) of the existing pulley type and peripheral parts, a pulley, Belts, tensioners, idlers, and high-voltage cables for HSG can be removed.

이로 인해 엔진룸 패키지를 개선하고, 부품 삭제로 인한 원가 절감 및 중량이 저감된 하이브리드 시스템을 개발할 수 있다.As a result, it is possible to improve the engine room package and develop a hybrid system with reduced costs and weight due to removal of parts.

또한, 본 발명의 실시 예는 기존에 스타트 모터에 일체로 구성되는 프론트 하우징을 변속기 케이스의 모터 커버 상에 형성하고, 이에 대응하여 스타트 모터를 변속기 케이스에 볼트 체결하는 방식으로 적용하여 수밀 구조에 유리하고, 케이블 등과의 간섭 회피 등, 용이한 장착성을 확보할 수 있다. In addition, an embodiment of the present invention is advantageous in watertight structure by forming a front housing integrally with the existing starter motor on the motor cover of the transmission case and bolting the start motor to the transmission case in response. It is possible to ensure easy mounting, such as avoiding interference with cables, etc.
