Description
본 발명은 전기 자동차의 유성기어형 변속기에 조립되는 기어의 나선방향을 설정하는 방법에 관한 것으로서, 특히 전동모터의 조립위치에 따라 조립되는 기어의 나선방향을 변경하여 전달되는 회전력의 전달성을 높이는 것과 더불어 밀착 조립되는 베어링의 수명을 연장하는 전기 자동차의 유성기어형 변속기 기어의 나선방향 설정방법에 관한 것이다.The present invention relates to a method of setting the spiral direction of a gear assembled to a planetary gear type transmission of an electric vehicle, and in particular, to improve the transferability of rotational force transmitted by changing the spiral direction of the gear assembled according to the assembly position of the electric motor. In addition, the present invention relates to a spiral setting method of a planetary gear transmission gear of an electric vehicle, which extends the life of a bearing to be closely assembled.
일반적으로 유성기어형 변속기는 보조 변속기의 일종으로서 현재 가장 일반적으로 사용되고 있는 것을 지칭하는 것이다. 상기 유성기어형 변속기는 엔진에서 나온 회전력을 유체를 이용하여 토크 컨버터가 2-3배의 회전력을 증대시킨다.In general, a planetary gear type transmission is a type of auxiliary transmission and refers to the most commonly used type at present. The planetary gearbox increases the torque of the torque converter by 2-3 times by using the rotational force from the engine.
상기와 같이 토크 컨버터에서 전달되는 회전력만으로는 실제 자동차의 주행에 있어서 필요한 구동력을 얻기에는 미흡하고, 또한 후진시 회전방향을 역회전시키는 역할을 하는 보조 변속기가 필요하다.As described above, only the rotational force transmitted from the torque converter is insufficient to obtain the driving force necessary for driving the actual vehicle, and also needs an auxiliary transmission that serves to reverse rotation of the rotational direction in reverse.
상기 유성기어형 변속기는 통상적으로 프런트 선기어 및 리어 선기어와 링기어 및 이들과 같은 축상에서 회전하는 캐리어에 지지되는 프런트 피니언 기어와 리어 피니언 기어로 구성되어 있으며, 선기어, 링기어, 캐리어의 3개 부분을 각각 고정 또는 구동하므로써 몇 개의 변속조합을 얻을 수 있다.The planetary gearbox is composed of a front pinion gear and a rear pinion gear and a rear pinion gear and a rear pinion gear which are supported by a front gear, a rear gear and a ring gear, and a carrier rotating on the same shaft. Several gear combinations can be obtained by fixing or driving each.
상기와 같은 유성기어형 변속기의 특징은 인지된 바와 같이 동력을 차단하지 않고 동력전달이 가능하고, 변속시 기어의 미끄러짐이 없고, 입력축과 출력축이 일직선상에 위치되며, 여러 가지의 변속비를 얻는 수 있는 특징이 있고, 1차 감속부(프런트 선기어) 및 2차 감속부(리어 선기어)와 차동기어부로 대별하여 나누어진다. 전술한 1, 2차 감속부에 조립되는 기어는 보다 우수한 맞물림을 얻기 위하여 헬리컬 기어로 구성되고 차동기어부는 헬리컬 또는 스퍼 기어를 사용한다.The characteristics of the planetary gearbox as described above is possible to transmit power without interrupting the power as recognized, there is no slip of the gear during shifting, the input shaft and the output shaft are located in a straight line, it is possible to obtain a variety of transmission ratio It is characterized by being divided into primary reduction gear (front sun gear), secondary reduction gear (rear sun gear) and differential gear parts. The gears assembled in the above-mentioned primary and secondary deceleration parts are composed of helical gears and the differential gear parts use helical or spur gears to obtain better engagement.
그러나, 상기와 같이 구성되어 작용하는 유성기어형 변속기는 전동모터의 장착위치에 따라 조립되는 1,2차 감속기어들의 조립구조가 다르게 형성되고, 상기 이유로 인해 헬리컬 기어의 나선방향의 설정을 잘못하면 추력이 한쪽으로 쏠리거나 밀착 조립되는 베어링이 파손되는 문제점이 발생한다.However, the planetary gear type transmission configured and operated as described above has a different assembly structure of the first and second reduction gears assembled according to the mounting position of the electric motor. There is a problem in that the bearings that are pulled to one side or assembled in close contact are broken.
따라서 본 발명은 상기와 같은 종래의 문제점을 해결하기 위하여 발명된 것으로, 전동모터의 장착위치에 따라 조립되는 기어의 나선방향을 달리 설정하여 전달되는 추력을 상쇄시킴과 동시에 유성기어형 변속기의 내구성을 향상시키는 데 그 목적이 있다.Therefore, the present invention was invented to solve the conventional problems as described above, and by setting the helical direction of the gear to be assembled according to the mounting position of the electric motor to offset the transmitted thrust and improve the durability of the planetary gear type transmission. The purpose is to make it.
상기의 목적을 구현하기 위한 구체적인 수단으로, 본 발명은 전동모터의 조립위치에 따라 1,2차 감속기어의 나선방향을 변경하여 설정하는 데 특징이 있다.As a specific means for realizing the above object, the present invention is characterized in that it is set by changing the helix direction of the first and second reduction gear according to the assembly position of the electric motor.

또한 2차 감속부는 선기어(4)의 나선방향은 왼쪽, 맞물리는 피니언 기어(5)는 오른쪽, 링기어(6)는 오른쪽으로 나선방향을 설정하여 차동기어부(7)로 변속조합되는 회전력을 전달한다.In addition, the secondary deceleration part sets the spiral direction of the sun gear 4 to the left, the interlocking pinion gear 5 to the right, and the ring gear 6 the right to the spiral to shift the combined torque to the differential gear 7. To pass.
한편 첨부도면 도 2는 전동모터의 조립위치가 왼쪽일 경우의 기어의 나선방향을 도시한 것으로서 1차 감속부의 선기어(1)는 나선방향이 왼쪽이고, 맞물리는 피니언 기어(2)는 오른쪽, 링기어(3)는 오른쪽으로 나선방향을 설정하여 전달되는 회전력을 변속하여 2차 감속부로 전달한다.On the other hand, Figure 2 shows the helical direction of the gear when the assembly position of the electric motor is left, the sun gear (1) of the primary reduction gear is the helical direction of the left side, the interlocking pinion gear (2) is the right, the ring The gear 3 shifts the rotational force transmitted by setting the spiral direction to the right side and transmits the rotational force to the secondary deceleration part.
상기와 같이 1차 감속부의 회전력을 전달받는 2차 감속부 기어의 나선방향은 선기어(4)의 나선방향은 오른쪽, 피니언 기어(5)는 왼쪽, 링기어(6) 또한 왼쪽으로 설정하여 변속되는 회전력을 차동기어부(7)로 전달한다.As described above, the helical direction of the secondary reduction gear receiving the rotational force of the primary reduction gear is shifted by setting the spiral direction of the sun gear 4 to the right, the pinion gear 5 to the left, and the ring gear 6 to the left. The torque is transmitted to the differential gear portion (7).
이상에서 설명한 바와 같이 본 발명은 전동모터의 조립위치에 따라 1,2차 감속부 기어의 나선방향을 변경 설정하여 전달되는 추력을 상쇄하는 것과 더불어 밀착 조립되는 베어링의 수명을 연장하여 유성기어형 변속기의 내구성을 향상시키는 효과가 있다.As described above, the present invention is to offset the thrust transmitted by changing the helical direction of the gears of the 1st and 2nd reduction gears according to the assembling position of the electric motor, and to extend the life of the bearing to be closely assembled to provide the planetary gear type transmission. It has the effect of improving durability.
