오토매틱 트랜스미션의 차동장치Differential of Automatic Transmission

본 고안은 오토매틱 트랜스미션(automatic transmission)의 차동장치(differential)에 관한 것으로, 특히 눈길, 빗길의 미끄럼을 방지하고, 동력을 좌, 우측 바퀴에 균등하게 배분시킬 수 있게 한 오토매틱 트랜스미션의 차동장치에 관한 것이다.The present invention relates to a differential of automatic transmission, and more particularly to a differential of automatic transmission which prevents slippage of snow and rain and distributes power evenly to left and right wheels. will be.

일반적으로 오토 트랜스미션은 엔진에서 전달되는 회전 속도 및 회전력을 변화시켜 구동륜에 전달하는 변속기의 작용을 변속 패턴(shift pattern)에 의해 자동적으로 이루어지도록 한 것으로서, 그 구성 요소를 설명하면, 토크 컨버터(torque converter), 작동기구(clutch, brake), 유성치차장치(planeetary gear set), 유압제어기구(valve body) 및 전자 제어장치(입력부, 제어부, 작동부) 등으로 구분할 수 있다.In general, the automatic transmission is to automatically perform the action of the transmission that changes the rotational speed and rotational force transmitted from the engine to the drive wheels by a shift pattern, the components of the torque converter (torque) converters, clutches, brakes, planetary gear sets, valve bodies, and electronic controls (input, control, operating).

상기와 같은 오토 트랜스미션은 유체 클러치를 이용하여 엔진의 동력을 전달 받아 입력축을 회전시키며, 기어 변속은 속도와 부하에 따라 유압제어기구에서 유압회로를 자동 변화시킴과 아울러 유성기어장치를 작동시킴으로써 각 단의 변속이 이루어지도록 되어 있다.The above-mentioned automatic transmission rotates the input shaft by receiving the engine power using the fluid clutch, and the gear shift automatically changes the hydraulic circuit in the hydraulic control mechanism according to the speed and load, and operates the planetary gear device. The shift is made.

오토매틱 트랜스미션은 구조가 복잡하고 제작이 어려우나 클러치 조작이 필요없고 동력 전달이 부드러워 차체 수명과 승차감이 뛰어나 널리 적용되고 있다.Automatic transmissions are widely applied due to their complex structure and difficulty in manufacturing, but do not require clutch operation and smooth power transmission, which has excellent body life and ride comfort.

도 1은 일반적인 오토매틱 트랜스미션의 전체 구성도로서, 도면중 1은 토크 컨버터, 2는 댐퍼 클러치, 3은 입력축(input shaft), 4는 킥 다운 드럼(kick down drum), 5는 펄스 제네레이터A(pulse generator - A), 6은 트랜스퍼 드리븐 기어(transfer driven gear), 7은 펄스 제너레이터B, 8은 트랜스퍼 샤프트(transfer shaft), 9는 차동장치(differential)에 관한 것이다.1 is an overall configuration diagram of a typical automatic transmission, in which 1 is a torque converter, 2 is a damper clutch, 3 is an input shaft, 4 is a kick down drum, and 5 is a pulse generator A. generator-A), 6 is the transfer driven gear, 7 is the pulse generator B, 8 is the transfer shaft, 9 is the differential.

상기 토크 텀버터(1)는 유체 클러치로서, 플라이 휠과 일체로 되어 있으며, 엔진이 회전하면 임펠러는 회전되고 임펠러의 날개에 의해 오일이 공급되어 터빈에 회전력이 전달되고 엔진의 동력은 변속기에 전달된다.The torque tumbler (1) is a fluid clutch, which is integral with the flywheel. When the engine rotates, the impeller rotates and oil is supplied by the impeller blades to transmit rotational force to the turbine, and the engine power is transmitted to the transmission. do.

상기 유체 클러치의 미끄럼 손실을 보완하기 위해 댐퍼 클러치(2)를 적용하여 연료비 효율을 향상시킨 오토매틱 트랜스미션을 사용하고 있고, 토크 컨버터(1)의 뒷면에 마찰 클러치(2)를 설치한 것으로서 작동시 토크 컨버터(1) 외에도 별도로 유압이 작동하여 댐퍼 클러치(2)를 프론트 커버에 밀착시켜서 엔진의 회전을 변속기의 입력축(3)에 전달한다.In order to compensate the slip loss of the fluid clutch, the damper clutch (2) is applied to the automatic transmission which improves fuel efficiency, and the friction clutch (2) is installed on the rear side of the torque converter (1). In addition to the converter 1, the hydraulic pressure is actuated separately to bring the damper clutch 2 into close contact with the front cover to transmit the rotation of the engine to the input shaft 3 of the transmission.

댐퍼 클러치(2)의 작용은 TCU(Transaxle Control Unit)에 의해서 전자적으로 유압 회로를 바꾸어 작동된다.The action of the damper clutch 2 is operated by electronically changing the hydraulic circuit by the Transaxle Control Unit (TCU).

상기 펄스 제너레이터A(5)는 킥 다운 드럼(4)의 회전수를 검출하고, 펄스 제너레이터B(7)는 트랜스퍼 샤프트(8)의 회전수를 검출한다.The pulse generator A 5 detects the rotational speed of the kick down drum 4, and the pulse generator B 7 detects the rotational speed of the transfer shaft 8.

컴퓨터(TCU)는 이 회전 속도를 참고로 변속 시기와 댐퍼 클러치(2)의 작동 신호를 결정하는 기준 신호이다.The computer TCU is a reference signal for determining the shift timing and the operation signal of the damper clutch 2 with reference to this rotational speed.

한편, 차동장치(9)는 주행중 좌우 바퀴의 회전차가 있을 때, 자동적으로 원활한 주행이 될 수 있도록 하는 역할을 한다.On the other hand, the differential device 9 serves to enable a smooth running automatically when there is a difference between the left and right wheels while driving.

그러나, 상기와 같은 일반적인 오토매틱 트랜스미션의 차동장치는 차동 작용을 제한하는 별도의 구성이 없으므로 눈길, 빗길의 미끄럼을 보다 효과적으로 방지하지 못하고 좌, 우 바퀴에 동력을 균등하게 배분하지 못하는 등의 문제점이 있었다.However, since the conventional automatic transmission differential device does not have a separate configuration limiting the differential action, there is a problem that it is not possible to effectively prevent slippage of snow and rain, and to distribute power evenly to the left and right wheels. .

따라서, 본 고안의 목적은 눈길, 빗길의 미끄럼을 방지하고, 동력을 좌, 우측 바퀴에 균등하게 배분시킬 수 있도록 한 오토매틱 트랜스미션의 차동장치를 제공함에 있다.Accordingly, an object of the present invention is to provide a differential transmission of an automatic transmission that prevents slippage of snow and rain and distributes power evenly to left and right wheels.

도 2는 본 고안의 차동장치가 구비된 오토매틱 트랜스미션의 구성도.2 is a block diagram of an automatic transmission equipped with a differential device of the present invention.
