본 발명은 차량용 자동 변속기의 4속 파워 트레인을 이용하여 5속 변속이 이루어질 수 있도록 함으로써, 동력성능 향상 및 연비향상을 도모할 수 있도록 한 자동 변속기의 파워 트레인에 관한 것이다.The present invention relates to a power train of an automatic transmission in which a five-speed shift can be made using a four-speed power train of an automatic transmission for a vehicle, thereby improving power performance and fuel economy.

예컨대, 차량용 자동 변속기의 파워 트레인은 각 자동차 메이커에 따라 형식을 달리하면서 개발되어 적용되고 있는데, 현재 통상적으로 사용되고 있는 자동 변속기는 4속 및 5속 변속기가 주류를 이루고 있다.For example, a power train of an automatic transmission for a vehicle has been developed and applied while changing the type according to each car maker, and the automatic transmission currently used is mainly composed of four speed and five speed transmissions.

이러한 예로서 5속 파워 트레인의 경우에는 대개 2개의 싱글 피니온 유성기어 셋트로 이루어지는 주변속부와, 1개의 싱글 피니언 유성기어셋트로 이루어지는 부변속부를 포함하여 이루어지는 것이 보편적이다.As an example, in the case of a five-speed power train, it is common to include a peripheral speed consisting of two single pinion planetary gear sets and a sub transmission part consisting of one single pinion planetary gear set.

즉, 도 4에서와 같이, 상기 주변속부(M)의 입력축(102)은 토오크 컨버터(TC)의 터어빈으로부터 동력을 전달받아 제1, 2 싱글 피니온 유성기어 셋트(104)(106)로 토오크를 전달하고, 이들 제1, 2 싱글 피니온 유성기어 셋트(104)(106)의 상호 보완적인 작동으로 변속이 이루어져 제1 싱글 피니온 유성기어 셋트(104)의 유성 캐리어(108)와 연결되어 있는 트랜스퍼 드라이브 기어(110)를 통해 출력될 수 있는 클러치 훅 업이 이루어진다.That is, as shown in FIG. 4, the input shaft 102 of the peripheral speed M receives torque from the turbine of the torque converter TC to torque the first and second single pinion planetary gear sets 104 and 106. And shifting is performed by the complementary operation of these first and second single pinion planetary gear sets 104 and 106, and is connected to the planet carrier 108 of the first single pinion planetary gear set 104. There is a clutch hook-up that can be output through the transfer drive gear 110.

그리고 상기 주변속부(M)는 출력요소로 작동하는 제1 유성 캐리어(108)와 제2 링기어(120)를 고정적으로 연결하고, 제1 링기어(114)와 제2 유성 캐리어(118)를 고정적으로 연결하되, 제1 선기어(112)와 제2 유성캐리어(118),그리고 제2 선기어(116)가 제1,2,3 클러치(C1)(C2)(C3)를 개재시켜 각각 입력축(102)과 가변 연결되어 3개의 입력요소를 보유하게 된다.The peripheral speed M is fixedly connected to the first planetary carrier 108 and the second ring gear 120 that operate as an output element, and connects the first ring gear 114 and the second planetary carrier 118 to each other. The first sun gear 112, the second planet carrier 118, and the second sun gear 116 are fixedly connected to each other via the first, second and third clutches C1, C2, and C3. 102 is variably connected to hold three input elements.

또한, 상기 제1 링기어(114)와 제2 유성 캐리어(118)를 연결하는 연결부재(122)가 제1 브레이크(B1)와 제1 원웨이 클러치(F1)에 의하여 하우징(124)에 가변 연결되고, 상기 제2 선기어(116)가 제2 브레이크(B2)에 의하여 하우징(124)에 가변 고정되어 2개의 고정요소를 보유하게 된다.In addition, the connecting member 122 connecting the first ring gear 114 and the second planet carrier 118 is variable to the housing 124 by the first brake B1 and the first one-way clutch F1. The second sun gear 116 is variably fixed to the housing 124 by the second brake B2 to hold two fixing elements.

그리고 상기 부변속부(S)는 제3 링기어(132)가 입력요소가 되고, 제3 선기어(128)가 출력요소로 작동하는 제3 유성 캐리어(130)와 제4 클러치(C4)를 개재시켜 연결됨과 동시에 제3 브레이크(B3) 및 제2 원웨이 클러치(F2)에 의하여 하우징(124)과 연결되는 구성이다.In addition, the sub transmission part S has a third ring gear 132 as an input element, and a third planetary carrier 130 and a fourth clutch C4 through which the third sun gear 128 operates as an output element. And connected to the housing 124 by the third brake B3 and the second one-way clutch F2.

그러나 상기와 같은 파워 트레인에 있어서는 주변속부와 부변속부로 나뉘고, 3개의 유성 기어셋트를 사용함으로써, 부피가 커질 뿐만 아니라, 중량이 증가되어 경량화에 역행한다는 문제점을 내포하고 있다.However, in the power train as described above, it is divided into a peripheral speed part and a sub transmission part, and by using three planetary gear sets, there is a problem that not only the volume is increased but also the weight is increased to counterweight the weight.

따라서 본 발명은 상기와 같은 문제점을 해결하기 위하여 발명된 것으로서, 본 발명의 목적은 기존의 4속 파워 트레인을 이용하여 5속화를 실현함으로써, 최적의 기어비로 연비와 동력성능 향상 및 경량화에 기여할 수 있도록 한 파워 트레인을 제공함에 있다.Therefore, the present invention has been invented to solve the above problems, the object of the present invention by realizing the five-speed using the existing four-speed power train, it can contribute to the fuel efficiency and power performance improvement and light weight with the optimal gear ratio To provide a power train.

또한, 후진 변속단을 2단화하여 동력 이용효율을 높일 수 있도록 한 파워 트레인을 제공함에 있다.In addition, it is to provide a power train that can increase the power utilization efficiency by two-stage reverse gear.

이하, 본 발명의 바람직한 실시예를 첨부한 도면을 참조하여 더욱 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in more detail.

도 1은 본 발명에 의한 파워 트레인의 스틱다이어그램으로서, 2개의 싱글 피니언 유성기어셋트(4)(6)와 5개의 클러치(C1)(C2)(C3)(C4)(C5)와, 2개의 브레이크(B1)(B2)의 클러치 훅업으로 이루어진다.1 is a stick diagram of a power train according to the present invention, which includes two single pinion planetary gear sets 4 and 6, five clutches C1, C2, C3, C4 and C5, and It consists of clutch hook-up of brake B1 (B2).

즉, 입력축(2)은 토오크 컨버터(TC)의 터어빈으로부터 동력을 전달받아 제1, 2 싱글 피니온 유성기어 셋트(4)(6)로 토오크를 전달하고, 이들 제1, 2 싱글 피니온 유성기어 셋트(4)(6)의 상호 보완적인 작동으로 변속이 이루어져 제1 싱글 피니온 유성기어 셋트(4)의 유성 캐리어(8)와 연결되어 있는 트랜스퍼 드라이브 기어(10)를 통해 출력될 수 있는 클러치 훅 업이 이루어진다.That is, the input shaft 2 receives power from the turbine of the torque converter TC and transmits torque to the first and second single pinion planetary gear sets 4 and 6, and the first and second single pinion planetary planets. Complementary operation of the gear sets 4 and 6 may be shifted and output via a transfer drive gear 10 connected to the planet carrier 8 of the first single-pinion planetary gear set 4. Clutch hook up is made.

보다 구체적으로는 출력요소로 작동하는 제1 유성 캐리어(8)와 제2 링기어(20)를 고정적으로 연결하고, 제1 링기어(14)와 제2 유성 캐리어(18)를 고정적으로 연결하되, 제1 선기어(12)와 제2 유성캐리어(18), 그리고 제2 선기어(16)가제1,2,3 클러치(C1)(C2)(C3)를 개재시켜 각각 입력축(2)과 가변 연결되어 3개의 입력요소를 보유하게 된다.More specifically, the first planetary carrier 8 and the second ring gear 20 which act as output elements are fixedly connected, and the first ring gear 14 and the second planetary carrier 18 are fixedly connected. And the first sun gear 12, the second planet carrier 18, and the second sun gear 16 are variably connected to the input shaft 2 via the first, second and third clutches C1, C2 and C3, respectively. It has three input elements.

또한, 상기 제1 링기어(14)와 제2 유성 캐리어(18)를 연결하는 연결부재(22)가 제1 브레이크(B1)와 제1 원웨이 클러치(F1)에 의하여 하우징(24)에 가변 연결되고, 상기 제2 선기어(16)가 제2 브레이크(B2)에 의하여 하우징(24)에 가변 고정되어 2개의 고정요소를 보유하게 된다.In addition, the connecting member 22 connecting the first ring gear 14 and the second planet carrier 18 is variable to the housing 24 by the first brake B1 and the first one-way clutch F1.

Is connected variably.

이러한 파워 크레인의 변속 제어과정을 도 2 및 도 3의 속도 선도와 마찰요소 작동표를 보면서 설명하면 다음과 같다.The shift control process of the power crane will be described with reference to the speed diagram and the friction element operation table of FIGS. 2 and 3 as follows.

도 2에 있어서의 레버의 각 노드는, 제1 유성 캐리어(8)와 제2 링기어(20)가 고정적으로 연결되고, 제1 링기어(14)와 제2 유성 캐리어(18)가 고정적으로 연결되는 바, 1 노드(N1)가 제1 선기어(12), 제2 노드(N2)가 제1 유성 캐리어(8)와 제2 링기어(20), 제3 노드(N3)가 제1 링기어(14)와 제2 유성 캐리어(18), 제4 노드(N4)가 제2 선기어(16)로 설정되며, 이의 노드 설정은 이미 공지된 방법이므로 상세한 설명은 생략하기로 한다.In each node of the lever in FIG. 2, the first planetary carrier 8 and the second ring gear 20 are fixedly connected, and the first ring gear 14 and the second planetary carrier 18 are fixedly. The first node N1 is connected to the first sun gear 12, the second node N2 is connected to the first planet carrier 8, the second ring gear 20, and the third node N3 is connected to the first ring. The gear 14, the second planet carrier 18, and the fourth node N4 are set as the second sun gear 16, and since the node setting thereof is already known, a detailed description thereof will be omitted.

먼저, 운전자가 전진을 위하여 셀렉트 레버를 D 레인지로 변환시키면, 트랜스밋션 제어유닛에서는 미도시한 자동 변속기 유압 제어시스템을 제어하여 제1, 4클러치(C1)(C4)와 제1 브레이크(B1)를 작동 제어한다.First, when the driver changes the select lever to the D range to move forward, the transmission control unit controls the automatic transmission hydraulic control system, not shown, so that the first and fourth clutches C1 and C4 and the first brake B1 are controlled. To control the operation.

그러면, 상기 제1 클러치(C1)가 작동되면서 제1 선기어(12)를 통해 입력이 이루어지고, 제1 브레이크(B1)의 작동에 의하여 제1 유성캐리어(8)와 제2 링기어(20)가 고정요소로 작동하게 되는 바, 제1노드(N1)가 입력요소로 작동하고, 제3노드(N3)가 고정요소로 작용하면서 제2 노드(N2)를 통해 제1속 출력이 이루어진다.Then, an input is made through the first sun gear 12 while the first clutch C1 is operated, and the first planet carrier 8 and the second ring gear 20 are operated by the operation of the first brake B1. Since the first node N1 acts as an input element and the third node N3 acts as a fixed element, a first speed output is made through the second node N2.

이러한 제1속 제어 상태에서 차속이 증가하게 되면, 트랜스밋션 제어 유닛에서는 상기 제1속 제어 상태에서 제1 브레이크(B1)의 작동을 해제하고, 제2 브레이크(B2)를 작동 제어한다.When the vehicle speed increases in the first speed control state, the transmission control unit releases the operation of the first brake B1 in the first speed control state and controls the second brake B2 in operation.

그러면, 고정요소가 제3노드(N3)에서 제4노드(N4)로 변환되면서 상기 제1속 보다는 감속비가 적은 상태로 출력되어 제2속 변속이 이루어지게 된다.Then, the fixed element is converted from the third node (N3) to the fourth node (N4) while being output with a reduction ratio less than the first speed to achieve a second speed shift.

이러한 제2속 상태에서 차속이 증가되면, 트랜스밋션 제어유닛에서는 상기 2속 상태에서 제2 브레이크(B2)를 작동 해제하고, 제2 클러치(C2)를 작동 제어한다.When the vehicle speed is increased in this second speed state, the transmission control unit releases the second brake B2 in the second speed state, and controls the second clutch C2 in operation.

그러면 입력이 제1, 2클러치(C1)(C2)에 의하여 이루어지게 되는 바, 제1, 3노드(N1)(N3)를 통해 입력이 이루어지면서 주변속부(M)는 직결의 상태가 되어 출력됨으로써, 3속의 변속이 이루어지게 된다.Then, the input is made by the first and second clutches C1 and C2. As the input is made through the first and third nodes N1 and N3, the peripheral speed M is directly connected and output. By doing so, three speed shifts are achieved.

이러한 3속의 상태에서 차속이 증가하면, 트랜스미션 제어유닛에서는 상기 3속의 상태에서 제1 브레이크(C1)의 작동을 해제하고, 제2 브레이크(B2)를 작동 제어한다.When the vehicle speed increases in the state of the third speed, the transmission control unit releases the operation of the first brake C1 in the state of the third speed, and controls the operation of the second brake B2.

그러면, 제3 노드(N3)로 입력이 이루어지고, 제4노드(N4)가 고정요소로 작용하게 되는 바, 오버 드라이브 상태가 되면서 4속 변속이 이루어지게 된다.Then, an input is made to the third node N3, and the fourth node N4 acts as a fixed element, and thus the four-speed shift is made while the overdrive state occurs.

이러한 제4속의 상태에서 차속이 증가하면, 트랜스밋션 제어유닛에서는 상기 제4속의 상태에서 제4 클러치(C4)의 작동을 해제하고, 제5 클러치(C5)를 작동 제어한다.When the vehicle speed increases in such a state of the fourth speed, the transmission control unit releases the operation of the fourth clutch C4 in the state of the fourth speed, and operates the fifth clutch C5 in an operation control manner.

그러면 상기 제 4속의 상태에서 출력요소가 제1 유성 캐리어(8)에서 제1 선기어(12)로 변환되면서 상기 4속 보다 큰 오버 드라이브 상태가 되어 5속 변속이 이루어지게 되는 것이다.Then, the output element is converted from the first planetary carrier 8 to the first sun gear 12 in the fourth speed state, and the overdrive state is larger than the four speeds, so that the five speed shift is performed.

즉, 제4속에서 출력요소의 변환으로 제5속 변속을 도모하게 되는 것이다.That is, the fifth speed shift is achieved by the conversion of the output element at the fourth speed.

또한, 후진 변속단에서는 제3,4 클러치(C3)와 제1 브레이크(B1)을 작동 제어함으로써, 제4노드(N4)로 입력이 이루어지고, 제3 노드(N3)가 고정요소로 작동하도록 하여 제1 후진 변속단을 얻을 수 있게 된다.In addition, in the reverse shift stage, the third and fourth clutch C3 and the first brake B1 are operated to control the input to the fourth node N4, and the third node N3 operates as a fixed element. Thus, the first reverse shift stage can be obtained.

그리고 상기의 상태에서 제4 클러치의 작동을 해제하고 제5 클러치(C5)를 작동 제어하면, 출력요소가 제1 노드(N1) 즉, 제1 선기어(12)로 변환되면서 상기 제1 후진 변속단보다 감속비가 더 큰 제2 후진 변속단을 실현할 수 있게 된다.When the fourth clutch is released and the fifth clutch C5 is operatively controlled in the above state, the output element is converted into the first node N1, that is, the first sun gear 12, and the first reverse shift stage is performed. It is possible to realize the second reverse shift stage with a larger reduction ratio.

물론 상기에서와 같이 후진 변속단을 2속으로 하고자 하는 경우에는 상기 2개의 후진제어가 이루어지도록 하면 되지만, 하나의 변속단만 요구되는 경우에는 필요로 하는 변속비에 따라 택일 제어할 수 있도록 설정하면 되는 것이다.Of course, when the reverse gear stage is set to 2 speed as described above, the two reverse controls may be performed. However, when only one gear stage is required, it may be set to control alternatively according to the required gear ratio. will be.

그리고 상기에서는 2개의 클러치(C4)(C5)를 이용하여 트랜스퍼 드라이브 기어(10)를 제1 선기어(12)와 제1 유성 캐리어(8)에 선택적으로 연결되도록 한 것을 설명하고 있으나, 이에 한정되는 것은 결코 아니며, 이외에도 트랜스퍼 드라이브 기어(10)를 선택적으로 제1 선기어(12)와 유성 캐리어(8)를 연결할 수 있는 구성이면 어떤 구조이든 만족한다.In the above description, the transfer drive gear 10 is selectively connected to the first sun gear 12 and the first planet carrier 8 by using two clutches C4 and C5. In addition, any structure can be satisfied as long as the transfer drive gear 10 can be selectively connected to the first sun gear 12 and the planetary carrier 8.
