전기자동차용 트랜스 액슬구조{Transformer axlestructure of electro-car}Transformer axlestructure of electro-car

본 발명은 전기자동차용 트랜스 액슬구조에 관한 것으로서, 더욱 상세하게는 변속기어의 구조를 간단하게 하여 부품수 감소로 인한 차챵의 경량화를 이루고 이에 따라 제조원가를 절감할 수 있도록 1단과 2단기어 전용인 전기 자동차의 트랜스 액슬 구조이다.The present invention relates to a transaxle structure for an electric vehicle, and more particularly, to simplify the structure of the transmission gear to achieve a lighter weight due to a reduction in the number of parts and thus to reduce manufacturing costs. The transaxle structure of an electric vehicle.

전기 자동차는 전기모터의 우수한 토오크 특성과 제어성을 십분 활용하여 제작되어지는 바, 기존의 내연기관을 장착한 차량에 비해 연소에 따른 공해가 전혀 없고 구동원이 되는 모터의 제어력이 우수하기 때문에 오래전부터 개발에 착수하여 실용화 단계에 이르고 있다.Electric cars are manufactured by taking full advantage of the excellent torque characteristics and controllability of electric motors. Since they have no pollution due to combustion and control power of the motor that is the driving source is superior to that of vehicles equipped with internal combustion engines, It has begun to develop and is at the stage of commercialization.

상기한 전기자동차의 구동원리는 축전지를 이용하여 모터를 구동시킴에 따라 모터의 힘으로 동력이 발생되게 한 것으로서 간단히 말하면 전기모터로 구동되는 자동차를 일컫는 것임은 주지하는 바와 같다.As described above, the driving principle of the electric vehicle is that the power is generated by the power of the motor as the motor is driven using the storage battery. In other words, the electric vehicle is driven by the electric motor.

이와 같은 전기 자동차는 축전지에 축적된 에너지(전기)가 한정되어 있기 때문에 그에 따른 주행속도의 저하와 고속 및 저속주행을 방지하고 개선하기 위한 변속기나 부대적인 작동수단의 변경과 대체가 시급한 실정에 이르고 있다고 할 수 있다.Since such electric vehicles have limited energy (electricity) accumulated in batteries, it is urgent to change and replace transmissions or auxiliary operation means to prevent and improve driving speed and to prevent and improve high and low speed driving. It can be said.

첨부한 도 1 을 참조하여 내연기관에서 사용된 1단 내지 5단기어 변속 및 후진기어장치를 차용채택한 종래 전기 자동차의 트랜스 액슬 구조를 상세하게 설명하면 다음과 같다.Referring to FIG. 1, a detailed description will be given of a transaxle structure of a conventional electric vehicle employing a 1 to 5 gear shift and a reverse gear device used in an internal combustion engine.

소정의 트랜스액슬케이스(9) 내부에 프라이머리쉬프트(1)와 세컨더리쉬프트(2)를 일측 및 타측에 위치고정시키고 상기 세컨더리쉬프트(2)의 일측에 차동주행장치(3)를 위치고정시킨다.The primary shift 1 and the secondary shift 2 are fixed to one side and the other side of the predetermined transaxle case 9 and the differential driving device 3 is fixed to one side of the secondary shift 2.

상기 차동주행장치(3)의 최종기어(3a)와 상기 세컨더리쉬프트(2)의 최종기어부재(2g)를 연계되도록 하고 상기 세컨더리쉬프트(2)의 외경에 1단, 2단, 3단, 4단, 5단기어(2a)(2b)(2c)(2d)(2e) 및 후진기어(2f)들 사이에 제3쉬프트기구(8)를 형성한다.The final gear 3a of the differential traveling device 3 and the final gear member 2g of the secondary shift 2 are connected to each other, and are arranged in the outer diameter of the secondary shift 2 in one, two, three, and four stages. However, the third shift mechanism 8 is formed between the five-stage gears 2a, 2b, 2c, 2d and 2e and the reverse gears 2f.

상기 프라이머리쉬프트(1)의 외경에 1단, 2단, 3단, 4단, 5단변속부재(1a)One-stage, two-stage, three-stage, four-stage, five-stage shifting member (1a) to the outer diameter of the primary shift (1)

(1b)(1c)(1d)(1e) 및 후진기어부재(1f)들 사이에 제1 및 제2쉬프트기구First and second shift mechanisms between (1b) (1c) (1d) (1e) and reverse gear member (1f)

(6)(7)를 형성한다.(6) (7) is formed.

상기와 같이 형성된 종래의 내연기관의 엔진(도시되지않음)에서 발생한 동력은 프라이머리샤프트(1)로 전달된다.The power generated in the engine (not shown) of the conventional internal combustion engine formed as described above is transmitted to the primary shaft 1.

이어서, 프라이머리쉬프트의 1단부터 5단까지 변속을 위해 형성된 1단, 2단 , 3단 , 4단 , 5단변속부재(1a)(1b)(1c)(1d)(1e)들과, 후진기어부재(1f) 중에 하나를 운전자가 선택하면 세컨더리쉬프트의 1단과, 2단과, 3단과, 4단과, 5단기어(2a)Subsequently, the 1st, 2nd, 3rd, 4th, and 5th speed shift members 1a, 1b, 1c, 1d, and 1e formed for shifting from 1st to 5th stage of the primary shift, When the driver selects one of the reverse gear members 1f, the first gear, the second gear, the third gear, the fourth gear and the fifth gear 2a of the secondary shift are selected.

(2b)(2c)(2d)(2e)들과, 후진기어(2f) 중에 하나를 연계적으로 회전시키는 제1 및 제2쉬프트기구(6)(7)가 회동한다.(2b) (2c) (2d) (2e) and the first and second shift mechanisms (6) (7) for rotating one of the reverse gears (2f) in rotation are rotated.

상기 제1 및 제2쉬프트기구(6)(7)가 회동하며 상기 프라이머리쉬프트(1)에 전달된 동력을 세컨더리쉬프트(2)에 전달할 때 상기 세컨더리쉬프트(2)의 일측부에 형성된 최종기어부재(2g)와 차량의 앞바퀴에 회전력을 전달하는 차동주행장치(3)의 최종기어(3a)가 기어물림된 상태에서 차동주행장치(3)의 최종기어(3a)를 회전시킨다.The final gear formed on one side of the secondary shift (2) when the first and second shift mechanism (6) (7) is rotated and the power transmitted to the primary shift (1) is transmitted to the secondary shift (2). The final gear 3a of the differential traveling device 3 is rotated while the final gear 3a of the differential traveling device 3 which transmits the rotational force to the member 2g and the front wheel of the vehicle is engaged.

상기와 같이 차동주행장치(3)의 최종기어(3a)가 회전하고 이에 따라 차량의 앞바퀴를 회전시키므로 차량이 전진 및 후진을 한다.As described above, since the final gear 3a of the differential driving device 3 rotates and thus rotates the front wheel of the vehicle, the vehicle moves forward and backward.

그러나, 상기한 바와 같은 전기 자동차에서는 고속주행에서 점차 저속주행으로의 변속을 필요로 할 때나 그 반대의 변속을 필요로 할 때를 위하여 기존 내연기관의 변속구조를 차용하여 채택하는 바 부품수가 많고 차중량이 증가하여 축전지의 불필요한 낭비가 초래되어 전기 자동차의 고유특성 중에 하나인 경량화와 저가의 유지비에 반한다는 문제점이 있었다.However, in the electric vehicle as described above, in order to require a shift from a high speed driving to a low speed driving or vice versa, the electric vehicle employs a shift structure of an existing internal combustion engine and has a large number of parts. The increase in weight causes unnecessary waste of accumulators, which is contrary to light weight and low cost maintenance, which are one of the inherent characteristics of electric vehicles.

상기와 같은 문제점을 해소하기 위하여 본 발명에 의한 전기 자동차의 트랜스 액슬구조는 1단 및 2단 기어를 전용으로 채택하여 전기 자동차의 앞바퀴를 구동시켜 차량의 주행이 이루어지며 복잡한 기어변속구조를 간단하게 하였으며 이에 따라 부품수를 대폭 감소하므로 차량의 경량화를 이루고 제조원가를 절감하는데 목적이 있다.In order to solve the above problems, the transaxle structure of the electric vehicle according to the present invention adopts the first and second gears exclusively to drive the front wheels of the electric vehicle to make the vehicle run and to simplify the complicated gear transmission structure. As a result, the number of parts is drastically reduced, and thus the purpose of the vehicle is to be lighter and to reduce manufacturing costs.
