첫번째로 구동 크랑크 부분에 지렛대의 원리를 적용하여 구동 토르크를 증대할 수 있도록한 크랑크 장치 구조 및 작동 과정을 설명하면 다음과 같다.First, the structure and the operation process of the crank device that can increase the drive torque by applying the principle of the lever to the drive crank portion are as follows.

그림 도 - 1 에서와 같이 크랑크 회전축(6)에 왕복기어 크랑크(5)를 고정설치하고 왕복기어 크랑크(5)는 왕복 내치기어(3)의 중심을 통하는 중앙홈을 따라 움직이는 베어링 롤러에 의해서 연결 하였다.As shown in Fig. 1, the reciprocating gear crank 5 is fixedly installed on the crank rotation shaft 6, and the reciprocating gear crank 5 is connected by a bearing roller moving along the center groove through the center of the reciprocating internal gear 3 It was.

왕복기어 크랑크(5)의 크랑크 운동에 의해서 왕복 내치기어(3)은 왕복 운동만을 하도록 왕복롤러(8)을 롤러 고정대(9)에 의해서 왕복 내치기어(3)의 양측에 고정 하였으며, 롤러 레일(10)을 설치 하였다.By the crank movement of the reciprocating gear crank (5), the reciprocating internal gear (3) fixed the reciprocating roller (8) to both sides of the reciprocating internal gear (3) by the roller holder (9) so as to perform only the reciprocating motion. 10) was installed.

유성기어 크랑크(4)는 왕복기어 크랑크(5)의 크랑크 반경 상에 설치 하였으며, 유성기어 크랑크(4)의 크랑크 반경은 왕복기어 크랑크(5) 반경의 1/2 이 되도록 하였다.The planetary gear crank (4) was installed on the crank radius of the reciprocating gear crank (5), the crank radius of the planetary gear crank (4) was to be 1/2 of the radius of the reciprocating gear crank (5).

유성기어(2)는 페달암(1)과 한 뭉치로 구성되여 유성기어 크랑크(4) 축에 연결하였다.Planetary gear (2) is composed of a pedal arm (1) and a bundle connected to the planetary gear crank (4) shaft.

유성기어(2)는 왕복 내치기어(3)과 접속되여 페달암(1)에 의해서 유성기어(2)가 회전시 왕복내치기어(3)은 직선 왕복운동을 하게 되고, 유성기어(2)는 유성 회전운동을 하게 된다.The planetary gear 2 is connected to the reciprocating internal gear 3 so that when the planetary gear 2 rotates by the pedal arm 1, the reciprocating internal gear 3 linearly reciprocates, and the planetary gear 2 is The planetary rotation will be performed.

이 유성회전운동은 곧 크랑크 회전축(6)을 회전시키는 크랑크 운동인 것이다.This planetary rotational motion is a crank motion to rotate the crank rotational shaft 6.

도 - 2 에서 지렛대 원리에 의한 토르크 변화를 고찰하면, 도 - 2 의 [2-2] 그림은 페달암이 수평을 유지하고 있는 위상으로 최대 토르크를 발휘 할 수 있는 위치이다.Considering the torque change based on the lever principle in Fig. 2, Fig. 2-2 shows the position where the pedal arm can exert the maximum torque in the horizontal phase.

이 위상에서 지렛대의 작용점을 살펴보면 "힘점" 이 되는 페달축 중심으로 부터 "받침점" 이 되는 유성기어의 중심까지의 거리는 페달축 중심으로 부터 크랑크 회전축(6)의 중심까지의 거리에 유성기어의 피치원 반경을 더한 값이다.Looking at the operating point of the lever in this phase, the distance from the center of the pedal shaft as the "force point" to the center of the planetary gear as the "support point" is the pitch of the planetary gear at the distance from the center of the pedal axis to the center of the crank rotation axis 6. The radius of the circle plus

"일점" 이 되는 곳은 왕복 내치기어(3)와 유성기어(2)가 접하는 점이 된다. "받침점" 으로부터 "일점" 까지의 거리는 유성기어의 반경과 같다.The "one point" becomes the point where the reciprocating internal gear 3 and the planetary gear 2 contact each other. The distance from "support point" to "one point" is equal to the radius of the planetary gear.

도 - 2 의 (2-3) 그림은 페달이 최저 위치에 있으며 페달암이 수직을 이루고 있는 위상으로 지렛대의 "작용점" 을 고찰하면 "받침점" 이 되는 곳은 유성기어(2)와 내치기어(3)이 접속되는 점으로 "힘점" 으로 부터 받침점 까지의 거리는 페달축 중심으로 부터 크랑크 회전축(6)의 중심까지의 거리이며, "일점" 이 되는 곳은 유성기어 중심이 된다.Figure (2-3) of Fig.-2 shows that the pedal is at the lowest position and the pedal arm is in a vertical phase. When the "action point" of the lever is considered, the point of support is the planetary gear 2 and the internal gear ( The point where 3) is connected is the distance from the "force point" to the support point is the distance from the center of the pedal shaft to the center of the crank axis of rotation 6, and the "one point" becomes the planetary gear center.

"일점" 으로부터 "받침점" 까지의 거리는 유성기어(2)의 반경과 같다. (2-2) 와 비교할때"힘점" 으로부터 "받침점" 까지의 거리 차이는 유성기어의 반경길이 만큼 나타난다.The distance from "one point" to "support point" is equal to the radius of the planetary gear 2. Compared with (2-2), the difference in distance from "strength point" to "support point" is represented by the radial length of the planetary gear.

즉 (2-3)에 비하여 (2-2) 의 경우 토르크가 증대되고 유성기어의 반경이 클수록 토르크가 증대되나 크랑크 구조 장치가 커지게 된다.That is, in the case of (2-2), the torque is increased and the torque is increased as the radius of the planetary gear is larger than in (2-3), but the crank structure device becomes larger.

둘째로 상반신의 좌우 운동을 크랑크 운동에 연동시켜 구동력을 강화 시킨 장치 구조에 관하여 설명 하기로 한다.Second, the structure of the device that strengthens the driving force by interlocking the left and right movement of the upper body to the crank movement will be described.

이미 언급한 크랑크 구조 및 작동 과정에서 왕복직선 운동을 하는 왕복내치기어(3)의 상단부에 강선을 그림(도-3) 에서와 같이 연결하여 탑승자의 상반신 좌우 운동을 크랑크 회전운동과 연동 시켰다.In the above-mentioned crank structure and operation process, the steel wire is connected to the upper end of the reciprocating internal gear 3 which performs the reciprocating linear motion as shown in Fig. 3, and the upper and lower left and right movements of the occupant are interlocked with the crank rotation motion.

안장 하부 차체에 +자형 트러스(21)를 고정 시키고 힌지를 설치하여 힌지를 중심으로 시소(22)가 작동 되도록 하였으며, 좌우측 왕복 내치기어를 연결한 강선이 일체의 벨트를 형성 하도록 시소(22)의 양단과 고정 트러스에 활차(24)를 설치 하였다.The + -shaped truss 21 is fixed to the lower body of the saddle and a hinge is installed so that the seesaw 22 operates around the hinge, and the steel wires connected to the left and right reciprocating internal gears form an integral belt. A pulley 24 was installed at both ends and a fixed truss.

상반신의 좌우운동은 시소운동을 유발케 하며 시소운동은 내치기어(3)의 왕복직선운동을 일으키게 하였다.The left and right movements of the upper body caused the seesaw movement and the seesaw movement caused the reciprocating linear movement of the internal gear (3).

필요에 따라 상체운동과 시소운동은 단절 시킬 수 있게 하였다.If necessary, the upper body and seesaw movements can be disconnected.

셋째로 2 인 탑승시 뒷좌석 탑승자의 운동 에너지를 구동력으로 전환 하기 위해서는 앞좌석 탑승자의 상반신 좌우 운동 레바를 전환하여 뒷자석 탑승자가 양팔을 좌우로 저어 시소운동을 일으키도록 한 것이다.Third, in order to convert the kinetic energy of the rear seat occupant into driving power when the two-person boarding is carried out, the rear seat occupant swings his arms from side to side to cause the seesaw movement by switching the upper and lower left and right movement levers of the front seat occupant.

이상 설명한 바와 같이 페달의 원운동 반경은 일정 하지만 지렛대의 원리를 적용하여 평시 크랑크의 회전력을 높이고 보다 강력한 구동력이 필요시 탑승자의 상반신 좌우 운동을 크랑크 운동으로 전환할 수 있도록 한 것은 마치 물고기가 느린 속도로 헤엄칠 때는 좌우 날개 지느러미 운동에 의존 하여 추진 하지만 빠른 속도로 전진할 때는 척추 운동에 의한 꼬리 지느러미를 이용 강력한 추진력을 내는 것과 흡사하다 하겠다.As described above, the radius of the circular movement of the pedal is constant, but the principle of the lever is used to increase the ordinary crank's rotational force and, if more powerful driving force is required, to convert the upper and lower left and right movements of the occupant into crank movement. When swimming with a fin, it relies on left and right wing fin movement, but when it moves forward at a high speed, it is similar to a strong propulsion using the tail fin by spine motion.

이와같이 구동 토르크를 증대시켜 기복이 심한 지형 조건에서 교통수단으로 자전거 활용도를 높일 수 있으며, 야지 운행이 가능하여 스포츠용으로 적용할 수 있는 자전거 크랑크 장치이다.In this way, by increasing the driving torque can increase the utilization of the bicycle as a means of transportation in the rugged terrain conditions, it is possible to apply the field of the bicycle crank device that can be applied for sports.
