Figure 4 is an exploded perspective view schematically showing the configuration of the power transmission device for an electric vehicle of the present invention, the pulley and the belt of the continuously variable transmission is not shown.
일반적으로, 전기 차량용 동력전달장치는 구동모터로부터 구동력을 전달받는 풀리장치와 종감속장치 및 차동기어장치가 순차적으로 구성되어, 상기 차동기어장치의 액슬샤프트에 결합된 바퀴의 회전에 의하여 차량을 움직이게 하는 장치로서, 본 발명의 동력전달장치에도 그대로 적용되는 공지기술이다.In general, a power transmission device for an electric vehicle includes a pulley device, a longitudinal reduction device, and a differential gear device sequentially receiving a driving force from a driving motor to move the vehicle by rotation of wheels coupled to the axle shaft of the differential gear device. As an apparatus to be used, it is a known technique applied as it is to the power transmission device of the present invention.
본 발명의 동력전달장치는, 도면에 제시된 바와 같이, 구동 모터(10)가 일측 외부면에 설치되고 무단변속장치(14)가 내부에 설치되는 하우징(제2하우징(2))과, 종감속장치(12)와 차동기어장치(13)가 내부에 설치되는 하우징(제1하우징(1))으로 구성된 전기 차량용 동력전달장치이다.In the power transmission device of the present invention, as shown in the drawings, the drive motor 10 is installed on one side of the outer surface and the continuously variable transmission device 14 is installed therein (second housing 2) and longitudinal deceleration A power transmission device for an electric vehicle composed of a housing (first housing 1) in which a device 12 and a differential gear device 13 are installed.
본 발명에 이용되는 상기 무단변속장치(14)는 차량의 부하나 속도에 따라 벨트(9)가 걸려있는 일력측 풀리(7)와 출력측 풀리(8)의 축경이 자동으로 변화되어 변속되는 장치로서, 전기차량분야에서 공연히 실시되고 있는 일반적 기술이며, 대한민국 특허 ' 등록번호 10-0431801 ' 에 제시된 자동변속풀리를 일예로 들 수 있다.The continuously variable transmission device 14 used in the present invention is a device in which the shaft diameters of the work force pulley 7 and the output pulley 8 on which the belt 9 is caught are automatically changed and shifted according to the load or speed of the vehicle. For example, the automatic transmission pulley is a general technology that is being performed in the field of electric vehicles, and the automatic transmission pulley presented in Korean patent 'Registration No. 10-0431801' is one example.
또한, 상기 종감속장치(12)와 차동기어장치(13) 등으로 구성된 기어장치도 종래부터 전기 차량 분야에서 공연히 실시되고 있는 기술임은 주지의 사실이다.In addition, it is well known that a gear device composed of the longitudinal reduction device 12, the differential gear device 13, and the like is also a technique that is conventionally performed in the electric vehicle field.
그런데, 종래의 전기 차량 동력전달장치는 차량의 디자인에 따라 1개의 하우징 내부에 무단변속장치와 종감속장치 및 차동기어장치 등이 설치된 일체형 구조로 제작되어진 것으로, 사용자의 요구에 따라 차량 내부공간만 일부 변경되는 정도의 작은 디자인 변경에도 동력전달장치를 새로 제작해야 하는 바, 이는 전기 차량이 일반화 되지않아 소량 생산되는 현실정에 비추어 비용과 효율면에서 적잖은 부담이 되어 왔다.However, the conventional electric vehicle power transmission device is manufactured in an integrated structure in which a continuously variable transmission, a longitudinal reduction gear, and a differential gear device are installed in one housing according to the design of the vehicle. Even with some minor design changes, new power trains have to be manufactured, which has been a significant burden in terms of cost and efficiency in light of the fact that electric vehicles are not common and are produced in small quantities.
따라서, 바퀴를 회전시키기 위한 차동기어장치(13)와 종감속장치(12) 등의 기어장치와, 구동 모터(10)로부터 구동력을 전달받아 상기 기어장치에 동력을 전달하는 무단변속장치(14)와, 하우징으로 구성된 전기 차량용 동력달장치에 있어서, 상기 하우징은 기어장치가 내부에 설치되는 제1하우징(1)과, 무단변속장치(14)가 설치되는 제2하우징(2)으로 별도 구성되고, 상기 제1하우징(1)과 제2하우징(2)의 결합부위는 축공이 형성된 플랜지형으로 성형되어 임의 각도로 제 1, 2하우징(1,2)이 볼트결합됨으로써, 전장과 외형이 쉽게 변형되는 것이 특징인 전기 차량용 동력전달장치를 안출하게 되었다.Therefore, a gear device such as a differential gear device 13 and a longitudinal reduction device 12 for rotating the wheels, and a continuously variable transmission 14 that receives power from a drive motor 10 and transmits power to the gear device. And, in the power transmission device for an electric vehicle composed of a housing, the housing is composed of a first housing (1) in which the gear device is installed therein, and a second housing (2) in which the continuously variable transmission (14) is installed. The coupling part of the first housing 1 and the second housing 2 is formed in a flange shape with a shaft hole, and the first and second housings 1 and 2 are bolted at an arbitrary angle, so that the overall length and the appearance are easy. An electric vehicle power train characterized by being deformed has been devised.
본 발명의 동력전달장치는, 구동모터(10)의 구동력을 바퀴에 전달하기 위하여, 무단변속장치(14)와 종감속장치(1) 및 차동기어장치(13)가 순차적으로 구성되며 이는 종래의 동력전달장치와 동일한 구성으로 일반적인 기술내용이다.In the power transmission device of the present invention, in order to transmit the driving force of the drive motor 10 to the wheel, the continuously variable transmission device 14, the longitudinal reduction gear device 1 and the differential gear device 13 are sequentially configured, which is a conventional It is a general technical content with the same configuration as the power transmission device.
본 발명의 제1, 2하우징(1, 2)의 플랜지형 결합부에는 축공이 형성되고, 이 축공에 종감속장치(12)의 입력축과 무단변속기(14)의 출력축 역할을 동시에 수행하는 1개의 통축이 관통되어 설치되는 것이 바람직하다.Shaft holes are formed in the flange-shaped coupling portions of the first and second housings 1 and 2 of the present invention, and one shaft that simultaneously serves as an input shaft of the longitudinal reduction gear 12 and an output shaft of the continuously variable transmission 14 is provided. It is preferable that the cylinder shaft penetrates.
또한, 상기 제2하우징(2)은 구동모터(10) 설치부위에 무단변속장치(14)의 입력축이 관통되는 축공이 형성된 돌출부(4)가 일체로 성형되고, 이 돌출부(4)의 단면부에 별도 제작된 어댑터플랜지(3)가 볼트 결합되게 구성되고, 상기 어댑터플랜지(3)에 구동모터(10)가 볼트결합되게 구성할 수 있다. 이와 같이 제2하우징(2)에 구동모터(10)를 직접 부착하지 않고 어댑터플랜지(3)를 매개로 간접 부착하는 것은 차량의 사양에 따라 다양한 종류의 구동 모터를 택일하여 용이하게 부착하기 위한 것으로, 구동모터의 고정브라켓이나 외형이 동일하지않기 때문이다.In addition, the second housing 2 is integrally formed with a protrusion 4 having a shaft hole through which the input shaft of the continuously variable transmission 14 penetrates into the installation portion of the drive motor 10, and an end portion of the protrusion 4. The adapter flange (3) manufactured separately is configured to be bolted, and the drive motor (10) may be configured to be bolted to the adapter flange (3). As described above, indirectly attaching the driving motor 10 to the second housing 2 via the adapter flange 3 is for easily attaching various types of driving motors according to the specification of the vehicle. This is because the fixing bracket and the appearance of the drive motor are not the same.
상기와 같이 두 부분의 하우징으로 구성된 본 발명의 동력전달장치를 디자인이 다른 차량에도 폭넓게 장착될 수 있는 장점이 있을 뿐만 아니라, 차후의 디자인 변경시에도 제1하우징부분이나 제2하우징부분 중 어느 한 부분의 변경만으로 필요 조건을 만족시킬 수 있으므로, 차량 디자인에 따라 동력전달장치의 외형을 새로이 제작할 필요성이 줄어들어, 결과적으로 보다 저렴한 가격에 전기 차량용 동력전달장치를 제공할 수 있는 장점이 있다.As described above, the power transmission device of the present invention consisting of a two-part housing not only has the advantage that it can be widely installed in a vehicle having a different design, but also any one of the first housing part or the second housing part in the case of subsequent design changes. Since only the change of the part can satisfy the requirement, the necessity of producing a new shape of the power transmission device according to the vehicle design is reduced, and as a result, the power transmission device for the electric vehicle can be provided at a lower price.
또한, 어댑터플랜지가 제공되어 구동모터의 고정 브라켓이나 외형에 관계없이 다양한 종류의 구동모터를 택일하여 용이하게 부착할 수 있는 장점이 있다.In addition, the adapter flange is provided, there is an advantage that can be easily attached to the various types of drive motors, regardless of the fixing bracket or the appearance of the drive motor.
