본 발명은 자동차용 자동변속기(Automatic Transmission)에 관한 것으로서, 더욱더 상세하게는 변속기의 길이를 짧게 하여 콤팩트화 할 수 있도록 함과 동시에 엔진 브레이크의 제어성이 향상되도록 하는 자동차용 자동변속기에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic transmission for an automobile, and more particularly, to an automatic transmission for an automobile for shortening the length of a transmission to be compact and at the same time improving controllability of an engine brake.

일반적으로 자동변속기는 클러치와 변속기의 조작을 사람 대신 기계가 하도 록 자동화한 것이며, 일반적인 수동변속기와 비교하면, In general, the automatic transmission is a machine that automates the operation of the clutch and the transmission instead of a human, and compared with a general manual transmission,

첫째, 차량의 운행상태에 말맞은 기어비로 일일이 기어의 변속조작을 하지 않아도 되므로 차량을 운행하는 운전자가 조작하지 않아도 되므로 운전하기가 편리하다.First, it is convenient to drive because the driver who operates the vehicle does not need to operate the gear shifting operation at a gear ratio appropriate to the driving state of the vehicle.

둘째, 운행 중 조작 미숙에 의하여 기관이 멈추는 일이 없기 때문에 운전자의 피로가 줄어들고 안전한 운행을 수행할 수 있다.Second, since the engine does not stop due to inexperienced operation during driving, the driver's fatigue can be reduced and safe driving can be performed.

셋째, 기관 회전력의 전달이 유체를 매개체로 하기 때문에 발진, 가속 및 감속이 원활하게 이루어진다.Third, since the transmission of the engine rotational force is a fluid medium, oscillation, acceleration, and deceleration are performed smoothly.

넷째, 유체가 댐퍼 역할을 하기 때문에 기관에서 동력전달장치나 바퀴, 기타 부분으로 전달되는 진동이나 충격을 흡수할 있으며, 또는 이와 반대로 바퀴에서 기관에 가해지는 진동이나 충격을 흡수하는 작용을 한다. 그리고 과부화가 걸려도 직접 기관에 가해지지 않으므로 기관을 보호하고 각 부분의 수명을 연장시킨다. 그런데 상기와 같은 장점과는 반대로 구조가 복잡하고 값이 비싸며, 연료소비율이 약 10% 정도 많아지고, 시동장치가 고장난 경우에는 차를 밀거나 끌어서 시동할 수 없다는 단점도 있다.Fourth, because the fluid acts as a damper to absorb the vibration or shock transmitted from the engine to the power transmission device, wheels, and other parts, or vice versa to absorb the vibration or shock applied to the engine from the wheel. In addition, overloading does not directly affect the trachea, thus protecting the trachea and extending the life of each part. By the way, in contrast to the advantages described above, the structure is complex and expensive, the fuel consumption rate is increased by about 10%, there is a disadvantage that can not start by pushing or dragging the car if the starter is broken.

여기에서 종래 자동차용 자동변속기는 도 1에 도시하고 잇는 바와 같이, 엔진의 동력을 전달하는 토오크컨버터에 의해 회전동력이 유입되도록 하는 입력축(100')과, 상기 입력축(100')에 유입된 회전동력에 의해 1,2,3,4,5,6의 변속이 이루어지도록 작동되는 브레이크(300') 및 클러치팩(200')으로 구성되어 있다.Here, as shown in FIG. 1, the conventional automatic transmission for a vehicle includes an input shaft 100 ′ for allowing rotational power to be introduced by a torque converter transmitting power of an engine, and a rotation introduced into the input shaft 100 ′. It is composed of a brake 300 'and a clutch pack 200' which are operated to achieve shifts of 1,2,3,4,5,6 by power.

이러한 종래 자동차용 자동변속기는 엔진의 동력을 전달하는 토오크컨버터에 의해 회전동력이 입력축(100')에 유입되면, 상기 입력축(100')에 유입된 회전동력은 유성기어(400')를 통해 클러치팩(200')과 브레이크(300')로 전달되면서 차량의 운행상태에 알맞은 변속비로 기어를 변속시키고 있다.When the conventional automatic transmission for a vehicle is a rotary power flows into the input shaft (100 ') by a torque converter for transmitting the power of the engine, the rotary power flows into the input shaft (100') is clutched through the planetary gear (400 '). It is transmitted to the pack 200 'and the brake 300' and the gear is shifted at a gear ratio suitable for the driving state of the vehicle.

그러나 이러한 종래 자동차용 자동변속기는 입력축(100')의 길이방향을 따라서 4,5,6속에서 작동하는 클러치팩(200')과 1,2,3,4,속에서 작동되는 브레이크(300')가 각각 설치되어 있는 관계로, 변속기를 제조시 변속기의 길이가 늘어나게 되어 전장이 길어지게 됨은 물론, 차량을 제작시 차량의 중량이 증가하여 차량의 연비를 저하시키게 되는 문제점이 있었다.However, such a conventional automatic transmission for a vehicle includes a clutch pack 200 'operating at 4, 5, and 6 speeds along a longitudinal direction of the input shaft 100', and a brake 300 'operating at 1, 2, 3, 4, speeds. Since each is installed, the length of the transmission is increased when the transmission is manufactured, as well as the overall length is long, as well as the weight of the vehicle increases when manufacturing the vehicle, thereby lowering the fuel economy of the vehicle.

한편, 종래 브레이크(300')는 밴드타입(Band Type')인 관계로, 입력축(100')을 통해 전달되는 회전력에 따라 즉각적이고 동일한 제어가 이루어지지 않아 제어성이 저하되게 되는 문제점이 있었다.On the other hand, the conventional brake 300 'is a band type (Band Type'), there is a problem that the controllability is lowered because the instant and the same control is not made according to the rotational force transmitted through the input shaft (100 ').

본 발명의 목적은 상기 종래와 같은 문제점을 해결하기 위해, 엔진의 동력을 전달하는 토오크컨버터에 의해 회전동력이 유입되도록 하는 입력축과, 상기 입력축에 유입된 회전동력에 의해 1,2,3,4,5,6의 변속이 이루어지도록 작동되는 다판식 브레이크 및 클러치팩으로 구성되고, 상기 클러치팩과 다판식 브레이크가 입력축의 동축상에 설치되는 것에 있어서, 상기 클러치 팩(200)은 출력축기어(500)와 오일펌프(600)사이에 설치되는 리액션서포트(610)에 의해 다판식 브레이크(300)가 지지되는 상태가 유지되도록 하여, 변속기의 길이가 축소된 상태에서도 변속이 용이하게 이루어지도록 함으로써, 차량을 제작시 전장을 축소시킬 수 있게 됨은 물론, 차량의 중량을 저감시켜 연비향상되도록 하는 효과가 있는 자동차용 자동변속기를 제공하는 데 있다.An object of the present invention is to solve the problems as described above, 1,2,3,4 by the input shaft and the rotational power introduced into the input shaft by the torque converter to transmit the power of the engine , 5, 6 is composed of a multi-plate brake and a clutch pack that is operated to achieve a shift, wherein the clutch pack and the multi-plate brake is installed on the coaxial of the input shaft, the clutch pack 200 is the output shaft gear 500 ) So that the multi-plate brake 300 is supported by the reaction support 610 installed between the oil pump 600 and the oil pump 600, so that the shift is easily performed even when the transmission length is reduced. It is possible to reduce the overall length at the time of manufacturing, as well as to provide an automatic transmission for an automobile that has the effect of reducing the weight of the vehicle to improve fuel efficiency.
