종래 4륜 차량의 연동장치로 트랜스 밋션부에 의한 전,후 변환기 샤프트와 디프렌셜 기어를 통하여 구동륜을 연동시키고, 2-3륜차에 있어서는 체인을 통해 구동륜을 회전시키고 있으나 전,후진이 불가능한 구조이다. 또한 트랜스 밋션은 고가이며 복잡한 기어장치가 소요되고 이에 따른 엔진오일이 과다히 소모될뿐 아니라 샤프트, 디프렌셜기어, 체인, 스프로킷이 외부로 노출되어 연동장치 전체가 거대해지고 각종저항체에 의한 파손의 위험이 많은 것이다.In the conventional four-wheeled vehicle linkage device, the drive wheels are interlocked by the front and rear converter shafts and differential gears by the transmission unit, and in the two- and three-wheeled cars, the drive wheels are rotated through the chain, but the forward and backward structures are impossible. to be. In addition, the transmission is expensive and requires complicated gears and excessively consumes engine oil, and the shaft, differential gear, chain, and sprocket are exposed to the outside, and the entire linkage is huge. There is a lot of risk.

본 발명은 종래의 차량 연동 메커니즘을 완전 탈피하여 2개의 기어펌프로서 오일을 정.역으로 순환시키고 이에 연동되는 기어펌프의 회전축으로서 차량을 전,후진 회전시키는 방식의 구동방식을 창출한 것으로서 그요지를 첨부도면에 의하여 상세히 설명하면 다음과 같다. 엔진, 모우터(l)의 구동축(la)을 제1기어펌프(2)의 회전축에 연결하고 이 제1기어펌프(2)의 오일유출관(3)은 압력균등기(4) 및 유로변환기(5)를 경유제2기어펌프(6)의 유입관(7)으로 배관하며 기어펌프(6)의 회전축(8)은 차량의 구동륜(도시없음)에 축설시켜 놓고 기어펌프(6)의 순환관(10)은 다시 유로변환기(5) 및 압력균등기(1l)을 경유 제1기어펌프(2)의 순환관(12)에 연결시키는 연동장치이다. 이 장치에 사용되는 유로변환기(5)는 내부밸브(13)가 레버(13a)에의해 회전되는데 제 4 도의 (가) 및 제 5 도와 같은 상태에서는 유출관(3)이 유로공(14)를 경유 유입관(7)에 일치되고 순환관(10)이 유로공(15)를 경유 순환관(12)에 일치된 상태에서 엔진, 모우터(1)의 동력이 제1기어펌프(2)를 회전시키게 되면 고압의 오일이 압력균등기(4)에 의하여 일정한 압력을 유지하며 유출관(3)에서 유로공(14)을 경유 유입관(7)으로 들어감과 동시 제2기어펌프(6)를 회전시켜 그 회전축(8)이 차량의 구동륜를 구동시킴으로서 전진 되는 것이고 순환관(10)은 다시 유로변환기(5)의 유로공(15)을 경유 압력균등기(11)에 의하여 일정한 압력을 유지하며 순환관(12)을 통하여 제1기어펌프(2)에 순환되는 것이다.The present invention is to create a driving method of rotating the vehicle forward and backward as a rotation axis of the gear pump circulating oil in the forward and reverse and two gear pumps to completely escape the conventional vehicle linkage mechanism. When described in detail by the accompanying drawings as follows. The drive shaft la of the engine and the motor 1 is connected to the rotary shaft of the first gear pump 2, and the oil outflow pipe 3 of the first gear pump 2 has a pressure equalizer 4 and a flow path converter. (5) is piped into the inlet pipe (7) of the second gear pump (6), the rotary shaft (8) of the gear pump (6) is laid on the drive wheel (not shown) of the vehicle and the circulation of the gear pump (6) The pipe 10 is again an interlocking device for connecting the flow path converter 5 and the pressure equalizer 1l to the circulation pipe 12 of the first gear pump 2 via. In the flow path converter 5 used in this apparatus, the inner valve 13 is rotated by the lever 13a, and in the same state as in Figs. 4A and 5D, the outlet pipe 3 opens the flow path 14. The power of the engine and the motor 1 is connected to the first gear pump 2 in a state in which the diesel oil inflow pipe 7 is matched and the circulation pipe 10 is coincided with the passage hole 15 in the diesel oil circulation pipe 12. When rotated, the high pressure oil maintains a constant pressure by the pressure equalizer 4 and enters the flow path 14 from the outlet pipe 3 into the diesel oil inlet pipe 7 and simultaneously opens the second gear pump 6. The rotating shaft 8 is rotated to drive the driving wheel of the vehicle, and the circulation pipe 10 is circulated while maintaining the constant pressure by the pressure equalizer 11 via the flow path hole 15 of the flow path converter 5. It is circulated to the first gear pump 2 through the pipe (12).

이 상태에서 레버(13a)을 당기면 제 4 도의 (b), 제 6 도의 (a)(b)와 같은 위치로 되는데 즉, 제 6 도의(a)와 같이 유출관(3)이 유로공(14)에서 밀폐됨과 동시 밸브(13)의 외면에 경사지게 파진 유로공(16)의 한쪽끝에 연통되고 유로공(16)의 다른쪽 끝은 순환관(10)에 연통되며 제 6 도의 (b)와 같이 순환관(12)는 유로공(15)에서 밀폐됨과 동시 밸브(13)의 다른쪽 외면에 경사지게 되면 유로공(17)의 한쪽 끝에 연통되고 유로공(17)의 다른쪽은 유입관(7)에 연통되는 것임으로 유출관(3)에서 유로공(16)을 경유 순환관(10)으로 들어가되 제2기어펌프(6)을 역회전시켜 그 회전축(8)이 차량의 구동륜를 역회전시킴으로서 후진되는 것이고이어 유입관(7)로 역류되어 유로공(17)을 경유 순환관(12)를 통해 제1기어펌프(2)로는 정상적으로 순환 복귀되는 것이다. 그러므로 본 발명의 전,후진장치는 오일순환과 방향변환에 의한 간단한 장치로서 수행되게하여 트랜스 미션의 전후 변환장치를 생략하고 샤프트나 체인류의 전동장치를 제거함으로서 차량의 부속과중량 및 연료소비를 줄이고 작동을 간결하게 하며 2륜차로 후진 가능케한 메카니즘임으로 널리 보급하여 실용화 시킬 수 있는 것이다.When the lever 13a is pulled in this state, it is in the same position as in (b) of FIG. 4 and (a) and (b) of FIG. 6, that is, as shown in (a) of FIG. ) Is communicated with one end of the passage hole 16 is inclined to the outer surface of the valve 13 at the same time and the other end of the passage hole 16 is in communication with the circulation pipe 10, as shown in (b) of FIG. The circulation tube 12 is closed at the passage hole 15 and is inclined to the other outer surface of the valve 13 at the same time so as to communicate with one end of the passage hole 17 and the other side of the passage hole 17 is the inlet tube 7. It is in communication with the flow passage hole (16) through the circulation pipe (10) in the outflow pipe (3), the second gear pump (6) is rotated reversely, the rotary shaft (8) reverses the drive wheel of the vehicle to reverse Then, the flow is reversed to the inflow pipe (7) to return to the first gear pump (2) normally circulating through the flow path hole (17) through the circulation pipe (12). Therefore, the forward and reverse devices of the present invention can be carried out as a simple device by oil circulation and direction change, eliminating the forward and backward conversion device of transmission, and eliminating the transmission, weight and fuel consumption of the vehicle. It is a mechanism that makes it simple to operate, simple to operate, and reversible by two-wheeled vehicle, and can be widely used for practical use.
