또한, 복합가변속장치의 효과적인 출력 제어를 위하여 출력축(3)의 상태를 감시 할 수 있는 센서(26)와 축압기(22) 내부 압력을 감지 할 수 있는 센서(27)를 구성하고, 입력 신호를 전선(28)(29)을 통해서 입력 받은 후 제어변(19)(21)(25)로 출력하도록 조정기(30) 및 전선(31)(32)(33)을 구성하였다.In addition, the sensor 26 for monitoring the state of the output shaft (3) and the sensor (27) for detecting the pressure inside the accumulator (22) for the effective output control of the complex variable speed gear, and the input signal The regulator 30 and the wires 31, 32, 33 were configured to be inputted through the wires 28 and 29 and then output to the control sides 19, 21, 25.

다음, 역회전 출력을 얻기 위하여, 차동장치(A)의 출력기어(7)는 출력기어(6)의 내부를 관통하여 유성기어열(B)의 케리어(9)와 동일한 부재로 구성하고, 일부를 돌출킨 후 케이스(1)와 케리어(9) 사이에 역전브레이크(34)를 구성하였다.Next, in order to obtain the reverse rotation output, the output gear 7 of the differential device A is made of the same member as the carrier 9 of the planetary gear train B, penetrating the inside of the output gear 6, and partially After protruding, the reverse brake 34 was configured between the case 1 and the carrier 9.

다음, 중립 상태 및 출력축(3)의 제동 상태를 얻기 위하여 유성기어열(B)의 링기어(10)와 케이스(1) 사이에는 중립브레이크(35)를 구성하였다.Next, a neutral brake 35 was formed between the ring gear 10 and the case 1 of the planetary gear train B to obtain a neutral state and a braking state of the output shaft 3.

중립 상태의 경우, 가변유체브레이크(C) 및 역전브레이크(34)를 개방하고 중립브레이크(35)를 구속한 상태에서 입력축(2)으로 구동력이 입력되어 화살표 방향으로 회전하면, 구동력은 차동장치(A)에서 차동되고 출력기어(6)(7)를 통하여 유성기어열(B)로 전달되며, 중립브레이크(35)에 의해서 제동된 링기어(10)에 의해서 케리어(9)가 입력축(2)과 반대로 역회전하고, 구동력은 출력축(3)으로 출력되지 않고 내부에서 공회전한다.In the neutral state, when the variable fluid brake C and the reverse brake 34 are opened and the neutral brake 35 is restrained, the driving force is input to the input shaft 2 and rotates in the direction of the arrow. The carrier 9 is driven by the ring gear 10 which is differential in A) and is transmitted to the planetary gear train B through the output gears 6 and 7, and braked by the neutral brake 35. Reversely reverses, the driving force is not output to the output shaft (3) but idling internally.

정회전 무단변속 출력의 경우, 상기 중립 상태에서 중립브레이크(35)를 개방하고, 가변유체브레이크(C)의 토출측 제어변(19)을 서서히 교축하면 선기어(8)와 일체인 제동기어(11)의 제동력이 선형적으로 증가하여 케리어(9)측 회전수가 증가하고, 선기어(8) 측 회전수는 감소하여 링기어(10)는 증속 출력 상태로 되고, 제어변(19)를 완전히 닫으면 링기어(10)는 최대 증속 출력 상태가 된다.In the case of the forward speed continuously variable output, when the neutral brake 35 is opened in the neutral state and the discharge side control valve 19 of the variable fluid brake C is gradually throttled, the braking gear 11 integral with the sun gear 8 is provided. ), The braking force increases linearly, the rotation speed of the carrier (9) side increases, the rotation speed of the sun gear (8) side decreases, and the ring gear 10 becomes the speed increase output state, and when the control valve 19 is completely closed, the ring The gear 10 is in the state of maximum speed output.

다음 역회전 출력의 경우, 가변유체브레이크(C)와 중립브레이크(35)를 개방 한 상태에서 역전브레이크(34)를 구속하면 입력축(2)의 구동력은 차동장치(A)에서 선기어(8)로 출력되고, 역전브레이크(34)에 구속된 케리어(9)에 의해서 링기어(10)는 최저 감속비의 역회전 상태로 출력되어 링기어(10)와 일체인 출력축(3)은 입력축(2)과 반대로 회전한다.In the case of the next reverse rotation output, if the reverse brake 34 is restrained with the variable fluid brake C and the neutral brake 35 open, the driving force of the input shaft 2 is shifted from the differential device A to the sun gear 8. The ring gear 10 is output in the reverse rotation state at the lowest reduction ratio by the carrier 9 restrained by the reverse brake 34 so that the output shaft 3 integral with the ring gear 10 is connected to the input shaft 2. Rotate in reverse.

다음 에너지 축척 모드의 경우, 입력축(2)과 출력축(3)이 동일한 방향인 화살표 방향으로 회전하고, 제어변(21)이 닫힌 상태에서 입력축(2)보다 출력축(3)이 속도가 증가하여 제동이 필요 할 경우, 역전브레이크(34)를 제동하고 제어변(19)을 개방한 상태에서 제어변(25)을 교축하면, 링기어(10)의 구동력은 제동된 케리어(9)에 의해서 선기어(8)는 역회전하고, 제동기어(11)는 입력축(2)과 반대방향으로 회전하며, 가변유체브레이크(C) 내의 유체(18)의 방향을 역으로 흐르게하고, 제어변(25)의 교축 정도에 따라서 유체(18)는 체크밸브(23)를 경유하여 축압기(22)에 축압되며, 축압 상태는 입력축(2)이 정지 할 때 까지 계속된다.In the next energy accumulation mode, the input shaft 2 and the output shaft 3 are rotated in the same direction as the arrow, and the output shaft 3 increases in speed than the input shaft 2 with the control valve 21 closed, thereby braking. If this is necessary, if the control brake 25 is throttled with the brake brake 34 and the control valve 19 open, the driving force of the ring gear 10 is the sun gear by the braked carrier 9. (8) rotates in reverse, the braking gear (11) rotates in the opposite direction to the input shaft (2), reverses the direction of the fluid (18) in the variable fluid brake (C), the control valve 25 Depending on the degree of throttling, the fluid 18 is accumulated in the accumulator 22 via the check valve 23, and the accumulating state continues until the input shaft 2 stops.

축압기(22)에 축압된 유체(18)를 재 사용 할 경우, 역전브레이크(34)를 제동 한 상태에서 제어변(19)을 닫고, 제어변(21)을 개방하면 제동기어(11)는 입력축(2)과 반대 방향으로 회전하며 동일 부재인 선기어(8)도 역회전하며, 링기어(10)는 제동된 케리어(9)에 의해서 입력축(2)과 동일 방향으로 구동력을 받는다.When reusing the accumulator fluid 18 in the accumulator 22, when the control brake 19 is closed with the reverse brake 34 braked, and the control valve 21 is opened, the brake gear 11 is closed. The sun gear 8 which rotates in the opposite direction to the input shaft 2 and is the same member also reversely rotates, and the ring gear 10 is driven by the braked carrier 9 in the same direction as the input shaft 2.

이때, 입력축(2)도 제동된 케리어(9)와 동일 부재인 출력기어(7)에 의해서 출력축(3)과 동일한 방향인 화살표 방향으로 구동력을 받는다.At this time, the input shaft 2 also receives the driving force in the direction of the arrow in the same direction as the output shaft 3 by the output gear 7 which is the same member as the braked carrier 9.

다음의 각 속도 모드의 경우, 조작 상태와 감속 비를 정리하면 다음과 같다.For each of the following speed modes, the operation status and deceleration ratio are summarized as follows.

이상의 각 속도 모드에 따르면, 변속 비는 유성기어열(B)의 잇빨수 비에 의해서 결정되므로 자동차 등에서 요구되는 변속 비를 감속에서 증속까지 용이하게 얻을 수 있으며, 특히 가변유체브레이크(C)를 사용하므로 응용 범위가 넓은 복합가변속장치가 가능하다.According to the above speed modes, the speed ratio is determined by the number of teeth of the planetary gear train (B), so that the speed ratio required for a vehicle can be easily obtained from deceleration to increase in speed. Thus, a variable speed transmission with a wide range of applications is possible.
