본 발명은 하이브리드 변속기용 축 토크 분배장치에 관한 것으로서, 더욱 상세하게는 동력을 전달하도록 하이브리드 변속기에 설치된 축에 가해지는 토크가 어느 일측에 가해지는 것을 방지하여 토크 집중으로 인한 파손을 방지할 수 있는 하이브리드 변속기용 축 토크 분배장치에 관한 것이다.The present invention relates to a shaft torque distribution device for a hybrid transmission, and more particularly, it is possible to prevent damage due to torque concentration by preventing torque applied to the shaft installed in the hybrid transmission to one side to transmit power. A shaft torque distribution device for a hybrid transmission.

일반적으로 하이브리드 전기 차량의 구동 방법은 차량에 탑재된 엔진과 모터 의 조합으로 차량을 주행하고 있다.In general, a hybrid electric vehicle is driven by a combination of an engine and a motor mounted on the vehicle.

하이브리드 전기 차량의 분류는 차량의 구동 방식에 따라 병렬형, 직렬형, 복합형 등이 있으며 엔진과 모터의 파워 분담비에 따라 마일드(Mild), 미들(Middle), 하드(Hard) 타입으로 분류한다.Hybrid electric vehicles are classified into parallel, series, and complex types according to the driving method of the vehicle, and classified into mild, middle, and hard types according to the power sharing ratio of the engine and the motor. .

예를 들어, 엔진의 용량에 비해 모터의 용량이 적은 형태를 마일드 하이브리드 시스템이라 한다.For example, a motor having a smaller capacity than that of an engine is called a mild hybrid system.

마일드 하이브리드 시스템의 전기 차량의 경우 모터(구동 모터, 전기 모터)로만 차량이 구동하는 모드는 없다.For electric vehicles in mild hybrid systems, there is no mode in which the vehicle is driven only by motors (drive motors, electric motors).

마일드 하이브리드 시스템의 경우 모터로 구동하는 모드는 없으나 모터를 사용하여 차량의 정지상태에서 가속시, 차량 주행중 추월 가속시에 순간적으로 높은 토크를 얻기 위해 엔진보다 응답성이 빠른 모터를 사용하여 차량이 주행에 필요한 토크를 공급하고 있다.There is no motor-driven mode in the mild hybrid system, but the vehicle is driven by using a motor that is more responsive than the engine in order to obtain instantaneous high torque when accelerating from the stationary state of the vehicle by using the motor and overtaking acceleration while driving the vehicle. Supplying the necessary torque.

한편, 도1은 종래의 하이브리드 변속기를 나타낸 단면도이다.1 is a cross-sectional view showing a conventional hybrid transmission.

여기에서 참조되는 바와 같이 종래의 하이브리드 변속기(1)는 동력을 전달하는 제1축(2)과 제2축(3)의 사이에 체인(4)이 설치되어 있다.As referred to herein, the conventional hybrid transmission 1 is provided with a chain 4 between the first shaft 2 and the second shaft 3 for transmitting power.

따라서, 엔진에서 발생된 동력은 체인(4)을 매개로 연결된 제1축(2)과 제2축(3)을 통하여 전달되는 것으로서, 상기 동력을 원활하게 전달하기 위해서는 체인(4)의 장력이 일정하게 유지되어야 한다.Therefore, the power generated in the engine is transmitted through the first shaft 2 and the second shaft 3 connected via the chain 4, and in order to smoothly transmit the power, the tension of the chain 4 is increased. Should be kept constant.

상기 체인(4)의 장력은 약 1000kgf로서 차량의 주행 및 정차시 엔진의 빈번한 온/오프 동작에 의해서 체인(4)으로 연결된 제1축(2) 및 제2축(3)에 집중적인 토크가 전달됨과 동시에 체인(4)의 장력이 변화되었다.The tension of the chain 4 is about 1000 kgf, and the torque concentrated on the first shaft 2 and the second shaft 3 connected to the chain 4 by frequent on / off operation of the engine when the vehicle is driven and stopped. At the same time the tension of the chain 4 was changed.

그러나 종래에는 체인(4)의 장력을 조절할 수 있는 어떠한 수단도 강구되지 않았으므로 장기간 사용시 체인(4)의 장력 변화로 인하여 동력을 원활하게 전달하지 못하였고, 심할 경우에는 체인(4)의 파손은 물론, 그 체인(4)의 파손으로 인하여 변속기 내부에 설치된 부품이 파손되는 등의 문제점이 있었다.However, in the related art, since no means for adjusting the tension of the chain 4 has been devised, power cannot be smoothly transmitted due to changes in the tension of the chain 4 when used for a long period of time. Of course, there is a problem that the parts installed inside the transmission are damaged due to the breakage of the chain 4.

본 발명은 상기한 문제점을 해결하기 위하여 발명한 것으로서, 그 목적은 동력을 전달하는 체인을 연장되게 설치하고 그 단부에 보조 스프라켓을 설치하여 동력 전달축에 가해지는 토크를 분배시켜 체인의 장력을 일정하게 유지할 수 있는 하이브리드 변속기용 축 토크 분배장치를 제공함에 있다.The present invention has been invented to solve the above problems, the purpose of which is to extend the chain for transmitting power and to install the auxiliary sprocket at its end to distribute the torque applied to the power transmission shaft to constant the tension of the chain To provide a shaft torque distribution device for a hybrid transmission that can be maintained.

상기 목적을 달성하기 위한 본 발명의 특징적인 구성을 설명하면 다음과 같다.Referring to the characteristic configuration of the present invention for achieving the above object is as follows.

본 발명의 하이브리드 변속기용 축 토크 분배장치는 엔진에서 발생된 회전전력을 전달하도록 변속기에 내장된 제1축과 제2축에 가해지는 토크를 분배시키도록 상기 제1축과 제2축과 일직선상에 설치된 보조 스프라켓과, 상기 제1축 및 제2축 그리고 보조 스프라켓이 감싸여지게 설치된 체인을 포함하여서 된 것이다.The shaft torque distribution device for a hybrid transmission of the present invention is in line with the first and second shafts so as to distribute torque applied to the first and second shafts built into the transmission to transmit the rotational power generated from the engine. It includes a secondary sprocket installed in the, and the first and second shafts and the chain is installed to surround the secondary sprocket.

이와 같은 특징을 갖는 본 발명을 상세하게 설명하면 다음과 같다.Referring to the present invention having such characteristics in detail as follows.

도2는 본 발명에 따른 축 토크 분배장치를 나타낸 단면도이고, 도3은 본 발명에 따른 축 토크 분배장치를 나타낸 개략도이다.Figure 2 is a cross-sectional view showing a shaft torque distribution device according to the present invention, Figure 3 is a schematic view showing a shaft torque distribution device according to the present invention.

On the shaft 2 and the second shaft 3, a sprocket 6 for power transmission is provided on the same line, respectively.

한편, 상기 변속기(1)의 내부에는 제1축(2)과 제2축(3)에 각각 설치된 동력 전달용 스프라켓(6)과 동일 선상에 위치되게 보조 스프라켓(5)이 설치되어 있되, 상기 동력 전달용 스프라켓(6)과 보조 스프라켓(5)에는 한 개의 체인(4)이 감싸여져 있다.On the other hand, the auxiliary sprocket 5 is installed in the transmission 1 so as to be located on the same line as the power transmission sprocket 6 installed on the first shaft 2 and the second shaft 3, respectively. One chain 4 is wrapped in the sprocket 6 and the auxiliary sprocket 5 for power transmission.

또한, 상기 보조 스프라켓(5)의 직경은 제1축(2) 및 제2축(3)에 설치된 동력 전달용 스프라켓(6)의 직경보다 작게 형성하는 것이 바람직하다. 왜냐하면, 체인(4)의 장력이 감소될 경우 그 체인(4)이 동력 전달용 스프라켓(6)에서 분리되는 것을 방지하기 위함이다.In addition, the diameter of the auxiliary sprocket 5 is preferably smaller than the diameter of the power transmission sprocket 6 provided on the first shaft 2 and the second shaft (3).

또한, 장기간 사용으로 인하여 체인(4)의 장력이 감소될 경우에는 보조 스프라켓(5)에 체인(4)이 감싸여져 있고, 상기 보조 스프라켓(5)은 동력 전달용 스프라켓(6)보다 직경이 작게 형성되어 있으므로, 체인(4)이 이탈되는 것이 방지되는 것이다. In addition, when the tension of the chain 4 is reduced due to long-term use, the chain 4 is wrapped in the auxiliary sprocket 5, and the auxiliary sprocket 5 has a smaller diameter than the power transmission sprocket 6. Since it is formed, the chain 4 is prevented from being separated.

이와 같이 본 발명은 하이브리드 변속기의 동력을 전달하는 제1축 및 제2축에 연결된 체인을 연장하고 상기 체인이 감싸여 지도록 변속기의 내부에 보조 스프라켓을 설치하여 동력 전달시 발생되는 토크를 분배시켜 토크의 집중으로 인한 변속기의 파손을 미연에 방지할 수 있게되는 특유의 효과가 있다.As such, the present invention extends the chain connected to the first and second shafts for transmitting power of the hybrid transmission, and installs an auxiliary sprocket inside the transmission so that the chain is wrapped, thereby distributing the torque generated during power transmission. There is a unique effect that can prevent the damage of the transmission due to the concentration of.
