Description

자전거의 지렛대 응용 추진장치{Lever application driving mechanism of The cycle}Lever application driving mechanism of the cycle

페달축(3)을 회전하여 동력을 뒷바퀴(19)에 전달함에 있어 지렛대우축(5)과 페달축(3)에 연결된 주동링크(4)에 의하여 지렛대양축(5)(8)이 상하반복운동을 하게 하고 지렛대좌축(8)에 의하여 주동스프로킷(15)에 동력이 전달 되도록 하였다.In rotating the pedal shaft 3 to transmit power to the rear wheel 19, the lever shaft 5 and 8 are moved up and down repeatedly by the lever link 4 connected to the lever shaft 5 and the pedal shaft 3. And the power was transmitted to the main sprocket 15 by the lever axle (8).

종래의 실시되지 안았던 이 분야의 고안에 따르면 자전거 몸체인 기본 틀을 많이 변형하여 그 구조를 페달의 상하반복운동으로 바꾼 것으로 종래의 페달 회전운동의 가속기(accelerator) 역할과 편리함, 그리고 오랜 관행을 무시 한 것으로 볼 수 있다.According to the design of this field, which has not been practiced in the past, the basic frame, which is a bicycle body, has been modified a lot, and its structure has been changed to the up and down repetition movement of the pedal. It can be seen as one.

현재 실시중인 종래의 일반화된 자전거는 크렌크축(1)에 주동스프로킷이 설치 되어 페달의 회전운동에 의하여 체인으로 연결된 종동스프로킷(16)을 회전시켜 동력이 뒷바퀴에 전달 되도록 하였다.The conventional generalized bicycle currently in operation has a main sprocket installed on the crankshaft (1) to rotate the driven sprocket (16) connected by a chain by the rotational movement of the pedal so that power is transmitted to the rear wheel.

종래의 자전거가 페달 회전운동에 의하여 종동스프로킷에 직접 동력을 전달하는데 반하여 본 고안은 링크(4)(9)와 지렛대(6)를 통한 간접방법으로 동력을 종동스프로킷(16)에 전달한 것이다.While the conventional bicycle directly transmits power to the driven sprocket by the pedal rotation movement, the present invention transmits the power to the driven sprocket 16 in an indirect manner through the link 4, 9 and the lever 6.

본 고안의 목적이 사절링크와 지렛대의 조합을 응용한 추진장치를 종래의 자전거 기본 틀에 설치해 페달 회전운동에 연계시켜 지렛대의 힘의 효율을 높이고자 한 것이다.The purpose of the present invention is to install a propulsion device applying a combination of a trimmer link and a lever to a conventional bicycle frame to link the pedal rotation movement to increase the efficiency of the lever force.

본 고안에 따르면 후렘의 기본은 종래의 것과 같으나 보조후렘(13)을 추가로 설치하여 주동스프로킷(15)을 기존의 크렌크축(1)에서 주동스프로킷축(11)으로 이동설치하고 후렘(12)은 상하수직으로 하여 지렛대 지지축(7)에 지렛대(6)를 설치한다. 페달축(3)과 지렛대우축(5)을 주동링크(4)로 연결하고 지렛대좌축(8)을 주동스프로킷(15)에 연결된 축(10)을 종동링크(9)로 연결한다. 이때 축(10) 상부에 래치휠을 축착하여 한 방향 회전을 차단, 전진방향으로만 회전케 한다. 또한 주동스프로킷축(11) 안쪽을 요철()축(20)으로 하여 변속시 좌우로 이동이 가능케 한다.According to the present invention, the base of the frem is the same as the conventional one, but additionally installed the auxiliary frem 13 to move the main sprocket 15 to the main sprocket shaft 11 from the existing crankshaft (1) and to install the hoem 12 The lever 6 is provided on the lever support shaft 7 in vertical and vertical direction. The pedal shaft 3 and the lever right and right shafts 5 are connected to the main link 4, and the lever 10 is connected to the main shaft sprocket 15 by the driven link 9. At this time, the latch wheel is attached to the upper part of the shaft 10 to block the rotation in one direction, so that it rotates only in the forward direction. In addition, the inside of the main sprocket shaft 11 is uneven ( With the shaft 20, it is possible to move left and right when shifting.

기타 프리휠이 장착된 뒷바퀴 차축(18), 다단계 변속기어로 구성된 종동스프로킷(16), 그리고 스프로킷에 연결된 체인(14), 변속작동에 필요한 보조스프로킷(17) 등은 종래의 것과 동일하다.Other freewheel-mounted rear wheel axles 18, driven sprockets 16 composed of multi-stage transmission gears, chain 14 connected to the sprockets, auxiliary sprockets 17 required for shifting operation, and the like are the same as in the prior art.

보조후렘(13)을 설치할 때 종동스프로킷(15)의 중심축(11)의 위치를 책정함에 있어 도3에 표시한 바와 같이 (18) (11) (8' )의 연장선과 (3' ) (1) (5' )의 연장선이 평행이 되고 (5)와 (8)의 연장선의 교차 각이 90도가 되며 (7)에서 (8)의 거리를 조정하여 결정하여야 한다.In setting the position of the central axis 11 of the driven sprocket 15 when installing the auxiliary harem 13, as shown in Fig. 3, the extension lines (3 ') (18) (11) (8') ( 1) The extension line of (5 ') is parallel, and the crossing angle of the extension lines of (5) and (8) is 90 degrees, and it should be determined by adjusting the distance of (7) to (8).

위에서 설명한 바와 같이 페달축(3)의 회전운동이 주동링크(4)에 의해 지렛대 상하운동을 거쳐 종동링크(9)에 전달되고, 다시 종동링크에 의해 주동스프로킷(15)의 회전운동이 체인(14)으로 연결된 종동스프로킷(16)에 동력이 간접 전달된다.As described above, the rotational movement of the pedal shaft 3 is transmitted to the driven link 9 through the lever up and down movement by the main link 4, and the rotational movement of the main sprocket 15 is further driven by the driven link. Power is indirectly transmitted to the driven sprockets 16 connected by 14).

페달 1회전이 미치는 주행력을 거리로 환산하면 바퀴의 크기에 따라 차이가 있으나 다단계 변속기어를 설치할 경우 바퀴반경 34cm를 기준으로 1.6회전에서 4.5회전한다. 이것은 3.5m에서 9.6m를 주행하는 거리다. 따라서 예를 들면 종전의 변속 1단 기어에 미치는 힘으로 5단 기어로 주행할 수 있다. 약 3배의 효율을 얻을 수 있는 샘이다. 특히 언덕을 오를 때 또는 무거운 짐을 실을 때 효과적이다.When converting the driving force of one pedal rotation into distance, it varies depending on the size of the wheel, but when installing the multi-stage transmission gear, it rotates from 1.6 to 4.5 rotations based on the 34cm wheel radius. This is a distance of 3.5m to 9.6m. Therefore, for example, it can drive with a 5th gear by the force applied to the previous gear 1st gear. It is a spring that can obtain about three times the efficiency. Especially when climbing hills or carrying heavy loads.

종래의 동력을 직접 전달하는 방법은 페달에 미치는 힘과 뒷바퀴에 전달된 힘의 비중이 동일함에 비해 본 고안은 지렛대지지축(7)을 중심으로 힘의 모멘트(moment)를 이용하여 중량 물을 움직이는데 사용되는 공지의 지렛대 응용을 페달축의 회전운동에 연계시켜 자전거 추진수단으로 하였으며 같은 거리를 주행하는데 필요한 페달 회전운동에 미치는 에너지를 줄이고 종래의 페달 회전운동의 가속력을 그대로 유지한 것이 특징이다. 또한 도3 B에 표시한 바와 같이 받침대(23)를 지지점(7)으로 한 지렛대우축(5)의 힘의 작용을 좌축(8)에 미치는 힘의 효율로 극대화 한 것이다.In the conventional method of directly transmitting power, the specific gravity of the force applied to the pedal and the force transmitted to the rear wheel is the same, whereas the present invention moves the heavy object using the moment of force around the lever support shaft (7). The known lever application is used in conjunction with the rotational movement of the pedal shaft as a bicycle propulsion means, and it is characterized by reducing the energy on the pedal rotational movement required to travel the same distance and maintaining the acceleration force of the conventional pedal rotational movement. In addition, as shown in Fig. 3B, the effect of the force of the lever right axis 5 having the pedestal 23 as the support point 7 is maximized by the efficiency of the force on the left axis 8.
