Description

진자운동에 의한 자전거의 구동장치{omitted}Driving device of bicycle by pendulum movement

본 발명은 자전거의 원활한 회전력과 힘의 효율을 높이기 위한 구동장치에 관한 것으로, 진자운동에 의한 상하왕복운동을 래크와 피니언기어, 베벨기어의 조합으로 회전운동으로 바꾸어 자전거가 전진 구동될 수 있게 한 구동장치에 관한 것이다.The present invention relates to a drive device for increasing the smooth rotational force and power efficiency of the bicycle, by changing the up and down reciprocating motion by the pendulum motion to the rotational movement by the combination of the rack, pinion gear, bevel gear to enable the bicycle to be driven forward It relates to a drive device.

일반적으로 이동, 운송, 운동용으로 사용하는 자전거는 크랭크축 상의 페달을 교대로 밟아 반원 회전 즉, 좌우 180˚ 회전의 반복으로 구동력을 발생하여 전진 운동한다. In general, a bicycle used for movement, transportation, and exercise generates forward driving force by repeatedly stepping on a pedal on a crankshaft, generating a driving force in a semicircular rotation, that is, rotating left and right 180 °.

페달을 한번 밟는 동안 크랭크축과 페달과 운전자의 힘의 중심점을 잇는 가상의 선을 그었을 때, 페달의 각이 직각을 이룰 때가 한 곳, 일직선을 이룰 때가 두 곳이 있게 된다.If you draw an imaginary line between the crankshaft, the pedal and the driver's center of gravity while you step on the pedal, there are two places where the angle of the pedal is at right angles and two at a straight line.

힘의 작용점을 각도와 관련하여 보면, 수직으로 누를 때가 가장 효율적임은 당연한바, 페달이 크랭크축과 운전자의 힘의 중심점과 이루는 가상의 각을 예로 들면, 페달이 상사점 근처 150˚에 있다면 둔각임으로 180˚-150˚=30˚으로 페달이 하사점 근처 30˚에 위치하는 것과 비슷해 직각을 이룰 때보다 힘이 회전력으로 변환되기가 원활하지 못하며, 세 점이 일직선상에 있으면 각은 0˚으로 발목과 무릎 등을 이용하지 않으면 회전하기 힘들어진다.If you look at the point of action of the force in relation to the angle, it is obvious that it is most efficient to press it vertically. Since the pedal is located at 30˚ near the bottom dead center with 180˚-150˚ = 30˚, the force is not smoothly converted to rotational force than when forming a right angle. When three points are in a straight line, the angle is 0˚. If you do not use the knees, etc. will be difficult to rotate.

즉, 페달과 크랭크축과의 길이가 같은 조건일 때는 페달에 수직으로 힘을 가할 때가 가장 효율이 좋고, 힘의 방향이 같은 각으로 페달에 전달된다면 페달과 크랭크축과의 길이가 길수록 유리하다. That is, when the length of the pedal and the crankshaft is the same condition, it is most efficient to apply the force vertically to the pedal, and the longer the length of the pedal and the crankshaft is advantageous if the direction of force is transmitted to the pedal at the same angle.

종래의 자전거는 페달이 반 바퀴 회전하는 동안 한 번만 직각이 되고, 두 번 일직선을 이루므로 효율이 낮은 문제점과, 페달과 회전축의 길이를 늘이는데 한계가 있는 근본 문제점이 있다. Conventional bicycles have a problem of low efficiency and a fundamental problem of limiting the length of the pedal and the rotating shaft because the pedal is perpendicular to the wheel only once and rotates twice while the pedal rotates half a turn.

본 발명은 상기한 바와 같은 문제점을 해결하기 위한 것으로서, 운전자의 족력이 페달에 효율적으로 전달되어, 전달된 힘이 진자운동에 의한 상하왕복운동에 의해 회전운동으로 바뀌어 자전거의 추진효율을 향상시킬 수 있게 한 구동장치를 제공함에 그 목적이 있다.The present invention is to solve the problems as described above, the driver's foot strength is effectively transmitted to the pedal, the transmitted force is changed to the rotational movement by the up and down reciprocation by the pendulum movement to improve the propulsion efficiency of the bicycle It is an object of the present invention to provide a driving device.

전술한 목적을 해결하기 위하여, 본 발명의 구동장치는In order to solve the above object, the driving device of the present invention

The left and right drive pinion gears 5a and 5b mounted on the drive shaft 8a so as to rotate in the forward and backward directions symmetrically, and the drive sprocket 8 is coupled to the right side of the right drive pinion gear 5b to connect the chain connected thereto. (9) is characterized in that the rear wheel 3 is coupled to the forward rotation by transmitting a rotational force to the driven sprocket 10.

상기 구동축 고정소켓(7) 앞쪽 방향에는 베벨기어 샤프트(17)에 의해 중심베벨기어(6)가 결합되여 좌우측 구동피니언기어(5a,5b)의 베벨기어와 치합 되게 설치하는 것을 특징으로 한다.The bevel gear shaft 17 is coupled to the center bevel gear 6 by the bevel gear shaft 17 in the forward direction of the drive shaft fixing socket 7 so as to be engaged with the bevel gears of the left and right driving pinion gears 5a and 5b.

상기 좌우측 구동피니언기어(5a,5b)의 피니언기어와 베벨기어와의 홈에 좌우측 풋바(4a,4b)의 좌우측 풋바가이드요부(12a,12b)가 삽입되면, 좌우측 래크기어(16a,16b)는 좌우측 구동피니언기어(5a,5b)의 피니언기어와 자동 치합되는 것을 특징으로 한다. When the left and right footbar guide recesses 12a and 12b of the left and right footbars 4a and 4b are inserted into the grooves between the pinion gear and the bevel gear of the left and right driving pinion gears 5a and 5b, the left and right rack gears 16a and 16b are inserted. Is characterized in that the automatic engagement with the pinion gear of the left and right drive pinion gear (5a, 5b).

상기 좌우측 풋바(4a,4b)의 풋바 중심축(11a,11b)을 프레임(1)의 좌우측 후륜(3) 부위에 고정된 좌우측 풋바중심축 고정소켓(15a,15b)에 결합하는 것을 특징으로 한다. The footbar center shafts 11a and 11b of the left and right footbars 4a and 4b are coupled to the left and right footbar center shaft fixing sockets 15a and 15b fixed to the left and right rear wheels 3 of the frame 1. .

상기 프레임(1)의 후륜(3)하단 좌우측에는 좌우측 행정조절고리(14a,14b)를 고정하는 것을 포함한다.It includes fixing the left and right stroke adjusting ring (14a, 14b) on the left and right sides of the lower wheel (3) of the frame (1).

본 발명은 종래 자전거가 페달의 원운동으로 추진력을 얻는데 반해, 페달 축을 길게 설치하여 페달이 긴 지렛대의 진자운동으로 상하왕복운동을 하여 페달 입사각에 의한 힘의 손실이 적으며, 왕복운동을 회전운동으로 바꿀 때 래크와 피니언기어를 사용하여 힘의 전달 효율이 높다.According to the present invention, the conventional bicycle obtains the propulsion force by the circular motion of the pedal, while the pedal shaft is long and the pedal is moved up and down by the pendulum movement of the long lever, so that the loss of the force due to the pedal incidence angle is small, and the reciprocating motion is rotated. When using the rack and pinion gears, the force transmission efficiency is high.

이는 같은 힘으로 더 빨리 달릴 수 있으며, 종래의 자전거로 오르기 힘든 경사진 언덕을 쉽게 오를 수 있는 장점이 있고, 기존의 디레일러식 기어변속기를 그대로 사용할 수 있으며, 기어비의 폭도 더 넓게 운용할 수 있다. It can run faster with the same force, has the advantage of easily climbing hills that are difficult to climb with a conventional bicycle, can use the existing derailleur gear transmission, and can operate a wider gear ratio.

또한, 구동피니언기어(5)에 레칫베어링이 내재되어 있어서 종동축 스프로킷(10)에 레칫베어링이 없어도 되어, 자전거가 전진 구동하고 있는 동안은 종동축 스프로킷(10)에 의해 체인이 항상 회전되어 별도의 발 구름 없이 언제든지 기어변속이 가능하게 되므로 자전거의 운전 편의성이 향상되는 효과가 있다. In addition, since the retracted bearing is inherent in the drive pinion gear 5, there is no need for the driven shaft sprocket 10 to have a ratchet bearing. While the bicycle is driven forward, the chain is always rotated by the driven shaft sprocket 10 so that Since the gear shift is possible at any time without the foot cloud, the driving convenience of the bicycle is improved.
