Abstract

The present invention can provide one to drive safely by immediately releasing a one-way rotation control for a pedal shaft to enable a pedal to freely rotate the pedal shaft in both directions when a reverse pedal operation is required to avoid dangers such as obstacles of a road and the like which occur accidentally or if the rotation of the pedal shaft is not required like when driving on a downhill road or when driving at high-speed and the like, whereas a prior one-way clutch pedal enables the pedal shaft to rotate only in one way. To this end, the present invention removes an inner wheel for a bearing to enable the direct friction with the pedal shaft and forms different axial diameters which prevents the operation of a clutch bearing (31) at a part having a small axial diameter but enables the operation of the clutch bearing when the invention is slid to a part having a large axial diameter, thereby solving the problem of a dead point and increasing the rotational force.

Description

한방향 클러치페달의 제어장치One-way clutch pedal controller
본 발명은 한방향 클러치베어링(one way clutch bearing)을 이용하여 페달축을 중심으로 한 페달몸체의 회전이 한 방향으로만 되게 하고, 상황에 따라서는 종래의 페달처럼 앞뒤 양방향으로 페달 발판을 선회시킬 수 있도록 하는 한방향클러치 페달의 제어장치에 관한 것이다.The present invention allows the rotation of the pedal body around the pedal shaft in only one direction by using a one way clutch bearing, so that the pedal foot can be rotated in both directions in the front and rear directions as in the conventional pedal. It relates to a control device of the one-way clutch pedal.
일반적으로 자전거페달은, 양방향으로 자유롭게 크랭크축을 중심으로 한 크랭크 암의 회전운동을 하는 구조에서, 크랭크 암의 축회전 각이 어느 각도에 위치하고 있어도 페달링하는 주행자의 신발바닥이 페달발판과 평행을 유지하기 위하여 양방향으로 자유롭게 페달축회전이 되게 하여 주행자의 발목을 보호하도록 되어 있으나, 이러한 양방향 페달축회전 페달에 가해진 주행자의 페달을 밟는 힘의 힘점이 항상 페달축에 걸리게 되어 힘의 효율을 떨어뜨리는 단점이 있다.In general, the bicycle pedal is a structure in which the crank arm rotates freely around the crankshaft in both directions so that the shoe sole of the pedaling driver is parallel to the pedal foot even when the axial rotation angle of the crank arm is positioned at any angle. In order to protect the driver's ankle by allowing the pedal shaft to rotate freely in both directions, the force point of the pedaling force of the driver applied to the bidirectional pedal shaft rotation pedal is always caught by the pedal shaft, reducing the efficiency of the force. have.
본 발명은 이를 개선하기 위해 한방향클러치페달을 개발하여 페달축회전이 크랭크축회전 방향과 반대방향으로만 되게 하여, 답력의 힘점이 페달축이 아닌 실제 힘을 가한 지점, 즉 페달발판의 앞쪽인 발앞쪽 끝부분으로 이동되게 함으로써, 크랭크 암의 길이(크랭크축∼페달축; 보통 170mm)가 '크랭크축∼페달발판 끝'으로 길어지게 하는 효과를 거둘 수 있게 하였다. 실예로 페달의 전장이 100mm일 경우, '페달축∼페달발판 끝'의 간격이 50mm이므로, 양방향 페달축회전 페달을 부착했을 때의 크랭크 암의 길이(170mm) 보다 50mm가 큰 230mm의 크랭크 암을 사용하는 것과 같은 효과를 올릴 수 있게 되었다. 크랭크 암의 길이가 길어진다고 해서 힘의 총량이 줄어드는 것은 아니지만, 지레대 역할을 하는 크랭크 암이 크면 같은 힘으로도 더 큰 힘을 얻을 수 있어 힘의 효율성을 유리하게 하였으나 동일한 효과를 가져다주는 변속기어장치가 보편화 되면서 밀려나게 되었다. 변속기어장치의 원리도 결과적으로 기어비; gear ratio 만큼의 지렛대 효과를 거두는 것이다. The present invention is to develop a one-way clutch pedal to improve the pedal shaft rotation only in the opposite direction to the crank shaft rotation direction, the point of the force of the pedal force is applied to the actual force, not the pedal shaft, that is the foot of the pedal foot By moving to the front end, it was possible to obtain the effect of lengthening the length of the crank arm (crank shaft to pedal shaft; usually 170 mm) to 'crank shaft to end of pedal pedal'. For example, if the length of the pedal is 100mm, the distance between the pedal shaft and the pedal pedal is 50mm, so the 230mm crank arm, which is 50mm larger than the length of the crank arm (170mm) when the pedal pedal rotates on both directions, is used. You can achieve the same effect as using it. The length of the crank arm does not reduce the total amount of force, but if the crank arm acts as a lever, a larger force can be obtained even with the same force, which is advantageous for the efficiency of the gear but has the same effect. Was pushed away as it became more common. The principle of the transmission gearbox also results in a gear ratio; The lever ratio is as much as the gear ratio.
그러나 변속기어장치도 사점(힘의 방향이 힘점과 작용점에 일직선상에 놓이게 되는 상사점과 하사점 부근의 힘의 공백지대) 만큼은 해소할 수가 없으며, 답력(직선운동에너지)이 회전력(회전운동에너지; torque)으로 전환되지 못하는 힘의 공백지대인 이 사점을 해소하기 위해서는 사점구간에 있는 힘점 및 힘의 방향을 변위시켜야 하고, 이를 위해서 양방향으로 페달축회전을 하는 페달의 축회전을 제어해야 하는데 이 때 본 발명에 따른 한방향 클러치베어링이 유용하다. However, the gearbox can't solve as much as the dead point (the dead zone of the force near the top dead center and the bottom dead center where the direction of force is in line with the point of force and the point of action), and the turning force (linear kinetic energy) is the rotational force (rotational kinetic energy). In order to solve this dead point, which is a void of force that cannot be converted to torque, the force point and the direction of force in the dead point section must be displaced, and for this purpose, the pedal rotation of the pedal which rotates in both directions is controlled. When the one-way clutch bearing according to the invention is useful.
즉, 사점구간에서 페달축회전을 억제하면 사점구간에 위치하고 있는 페달축에 집중된 힘점이 사점구간 밖에 위치한 페달발판 앞쪽 끝으로 이동하게 되고, 이렇게 이동된 힘점에서부터 새로운 힘의 방향에 의해 힘의 작용선이 생기게 되어 답력이 회전력으로 전환되게 되는 것이다. 그러나 한방향클러치페달은 구조적으로 크랭크축회전 방향으로는 페달축회전이 불가능하게 되어 있어 안전주행을 위한 역페달링(진행방향의 반대방향으로 페달을 젓는 페달링; back pedaling)이 불가능 하고, 페달축회전을 한 방향으로만 억제함이 오히려 방해가 되는 평속주행(힘들이지 않고 가볍게 타는 평상시 주행을 의미)이나 내리막길 등에서도 계속 한 방향으로 억제되어 있어 위험과 불편을 초래하고 있다.That is, when the pedal shaft rotation is suppressed in the dead point section, the force point concentrated on the pedal shaft located in the dead point section is moved to the front end of the pedal footrest located outside the dead point section, and the line of action of the force is moved by the new direction of force from the moved point. Will be converted into turning force. However, the one-way clutch pedal is structurally impossible to rotate the pedal shaft in the crankshaft direction, so it is impossible to reverse pedaling for safe driving (back pedaling in the opposite direction of the driving direction) and to rotate the pedal shaft. It is dangerous and uncomfortable because it is continuously suppressed in one direction even in the case of flat driving (meaning normal driving that takes light weight without effort) or downhill where restraining is limited in only one direction.
자전거를 타다보면 역페달링을 해야만 되는 경우가 헤아릴 수 없이 많다. 그래서 종래의 페달이 양방향으로 페달축회전이 되도록 만들고 그것을 사용하고 있는 것이다. 역페달링이 꼭 필요한 몇 가지 사례를 들자면, 먼저 도로에서의 안전주행을 위해서 필요한 경우로, 페달의 지상고(하사점에 위치한 페달 밑면과 지면; 地面의 간격)보다 큰 장애물이나 도로 가장자리의 경계석(인도블록 턱 등)에 페달이 걸리지 않게 하기 위한 경우와, 심한 요철이나 턱이 진 노면을 주행할 경우와, 급커브에서 코너링을 할 때 안쪽 페달이 지면에 닿지 않도록 하기 위한 경우 등이 있다. 특히 휴대와 보관이 용이하여 도심에서 많이 타는 접이식자전거; folding bike나 미니벨로는 대부분이 적은 바퀴로 만들어져 있어 일반자전거에 비해 페달의 지상고가 훨씬 낮기 때문에 주행 중 역페달링이 더 많이 필요하며, 노면에 장애물이 많은 산악자전거를 탈 때에도 그 빈도가 훨씬 많아진다. When you ride a bicycle, you have to count backwards. So, the conventional pedal is to make the pedal shaft rotation in both directions and use it. Some examples of the need for reverse pedaling include, but are not limited to, roadblocks that are larger than the pedal ground clearance (the bottom of the pedal at the bottom dead center and the ground; the gap between the ground), which is necessary for safe driving on the road. There are cases where the pedal is not caught on the block jaw, etc., when driving on a rough road with severe bumps or bumps, and when the inner pedal does not touch the ground when cornering in a sharp curve. In particular, it is easy to carry and store a lot of folding bikes in the city; Since most of the folding bikes and mini bells are made of fewer wheels, the pedal's ground clearance is much lower than that of ordinary bicycles, so more reverse pedaling is required during driving, and the frequency is much higher when riding mountain bikes with many obstacles on the road. .
그 밖에도 정지된 자전거를 출발시킬 때 크랭크 회전각과 페달의 수평을 최적의 위치로 벼르기 위해서도 페달의 양방향 축회전이 필요한데, 이는 관성에너지가 생기지 않아 답력만으로 회전력을 얻기 위해서는 크랭크 암을 최유효회전각(시계방향으로 축회전할 때 2시 방향)으로 벼르고, 그렇게 벼루어진 크랭크 암에 주행자의 발목이 순응할 수 있도록 페달도 적절하게 페달축회전이 되어야 하기 때문이다. 또한 사이클 선수나 마니아들은 앵클링(: ankling 상사점에서는 페달을 앞으로 밀고 하사점에서는 뒤로 당기며 업스트로크 구간에서는 뒷발질로 페달을 끌어올리는 페달링 방법)을 하기 위해서 클립페달(페달에 신발을 결합시킨 페달)을 착용하기에 한방향클러치페달을 사용할 경우 역페달링시 발목이 꺾이게 되므로 반드시 양방향 페달축회전이 필요하다.In addition, when starting a stationary bicycle, the pedal's bidirectional axial rotation is also necessary in order to shift the crank rotation angle and the pedal level to the optimum position. This is because the pedal must be properly rotated to allow the rider's ankle to conform to the crank arm that is so struck. Cyclists and enthusiasts also use the clip pedal (pedal with pedal to pedal) for ankling (a pedaling method that pushes the pedal forward at the top dead center, pulls it back at the bottom dead center, and pulls the pedal back to the rear at the upstroke). If you use the one-way clutch pedal to wear), the ankle is bent when reverse pedaling, so the bidirectional pedal shaft rotation is necessary.
본 발명의 목적은 페달이 한 방향으로만 페달축회전이 억제되어 있는 상태에서 돌발적으로 발생하는 노면의 장애물 등 위험을 피하기 위한 역페달링이나, 내리막길이나 고속주행 등과 같이 페달축회전이 필요하지 않을 때에는 한 방향 페달축회전 제어를 즉시 해제하여 페달이 양방향으로 자유롭게 축회전을 할 수 있도록 하여 안전주행을 할 수 있게 하기 위한 것이다.An object of the present invention is to avoid pedal pedal rotation, such as reverse pedaling to avoid danger, such as road obstacles that occur suddenly in a state where the pedal shaft rotation is suppressed in only one direction, such as downhill road or high speed driving. When the one-way pedal shaft rotation control is released immediately to allow the pedal to rotate freely in both directions to allow safe driving.
또한 본 발명은, 평상시에는 페달이 양방향으로 자유롭게 축회전을 할 수 있도록 하고, 관성에너지가 생기지 않은 정지된 자전거를 출발시킬 때나 관성이 소멸되고 있는 경사로(傾斜路)를 주행할 때에는 본 발명에 따른 한방향 클러치베어링을 작동시켜 사점 해소와 힘의 효율을 높이도록 함에 그 목적이 있다In addition, the present invention is to allow the pedal to rotate freely in both directions in normal times, when starting a stationary bicycle without inertia energy, or when driving on a ramp where the inertia is disappearing. The purpose of this is to operate the one-way clutch bearing to eliminate dead points and increase the efficiency of the force.
본 발명은 대부분의 자전거 주행구간이 한방향클러치가 요구되지 않음을 고려하여 임의로 한방향클러치베어링을 작동시키지 않는 한 보통의 양방향 페달축회전 페달처럼 페달축받이에 지지하여 편리하게 사용할 수 있게 하다가, 페달축회전의 억제가 필요할 때에만 한방향클러치베어링을 작동시켜 유용하게 사용할 수 있도록 하였다.According to the present invention, most bicycle driving zones do not require a one-way clutch, so that the one-way clutch bearing can be conveniently supported on the pedal support like a normal two-way pedal axle pedal unless the one-way clutch bearing is operated. One-way clutch bearings are operated only when the suppression of
또한 한방향클러치베어링의 제어가 페달에서 발을 떼지 않고도 간편하게 할 수 있도록 페달축을 따라 좌우로 슬라이딩 동작으로 작동되게 하여 평페달은 물론 클립페달에서도 손쉽게 사용토록 하였고, 오르막길 주행으로 페달에 체중을 실은 상태에서 더 큰 힘이 필요하여 한방향클러치베어링을 작동시켜야 할 때나, 무게중심을 낮추기 위해 페달에 체중을 얻고 내리막 주행을 하다가 갑자기 역페달링이 필요하여 클러치 작동을 해제해야 할 때 등과 같이 고부하(高負荷) 상태에서도 해제가 용이하도록 하였다.In addition, the control of the one-way clutch bearing is operated by sliding left and right along the pedal axis so that the control of the one-way clutch bearing can be done easily without taking your foot off the pedal. Even at high loads, such as when one-way clutch bearings need to be activated due to a large force, or when you gain weight on the pedals to lower the center of gravity and drive downhill while suddenly reverse pedaling is required to release the clutch. It was easy to release.
본 발명에 의하면 한방향 클러치베어링을 활용하여 관성에너지가 없는 상태에서의 사점 구간에서도 일정량의 회전력을 얻게 하여 자전거 타기의 큰 장애물인 오르막길 등판 주행을 수월하게 하며, 한 방향으로만 페달축회전이 고정되어 역페달링이 불가능했던 문제를 해결하여 안전 주행을 할 수 있도록 하였고, 제어방식을 간편하게 하여 언제 어떤 상황에서도 한방향 클러치베어링을 제어하게 함으로써 이용범위와 사용효과를 더욱 높였다.According to the present invention by utilizing the one-way clutch bearing to obtain a certain amount of torque even in the dead point section in the absence of inertial energy to facilitate the uphill road running, which is a big obstacle of riding a bicycle, the pedal shaft rotation is fixed only in one direction It solved the problem that reverse pedaling was impossible, so that it was possible to drive safely, and the control method was simplified so that one-way clutch bearing could be controlled at any time and in any situation, thereby increasing the range of use and the effect of use.

본 발명을 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
먼저, 도 1a 에서 보듯이, 크랭크아암(41)에는 페달축(11)이 고정되고, 페달바(23)를 포함하는 페달프레임(21)이 페달축(11)에 장착되며, 이의 고정을 위해 패킹(43), 와셔(44), 캡너트(45) 등으로 고정된다First, as shown in Figure 1a, the crank arm 41 is fixed to the pedal shaft 11, the pedal frame 21 including the pedal bar 23 is mounted on the pedal shaft 11, for fixing thereof Secured with packing 43, washer 44, cap nut 45, and the like.
본 발명은 페달축(11)의 일부분을 가공하여 테이퍼 가공면(13)을 형성하였다. 페달축(11)에는 베어링(51) 외에 추가로 클러치베어링(31)을 설치하였다In the present invention, a portion of the pedal shaft 11 is processed to form a tapered working surface 13. The pedal shaft 11 is provided with a clutch bearing 31 in addition to the bearing 51.
클러치베어링(31)은 그 외주가 클러치베어링 외륜(52)을 구성하고 있으며, 이 외륜(52)의 고정은, 페달프레임(21)을 가공하여 수용홈(33)이 형성되게 하여 여기에 클러치베어링 외륜(52)이 고정되게 설치한다The outer circumference of the clutch bearing 31 constitutes the outer ring 52 of the clutch bearing. The fixing of the outer ring 52 causes the receiving frame 33 to be formed by machining the pedal frame 21, and thus the clutch bearing. Install outer ring 52 fixed
그리고 상기한 클러치베어링(31)은, 그 내장되는 베어링 볼이 구름작용과 좌우 밀림(thrust) 작용을 같이 할 수 있도록 하기 위해, 그의 내륜이 없이 돌출되어 페달축(11) 외면에 접촉될 수 있게 구성하되, 도 3에서 보듯이 리테이너(54)가 베어링(51)을 잡아주도록 구성한다.In addition, the clutch bearing 31 is protruded without its inner ring to be able to contact the outer surface of the pedal shaft 11 so that the bearing ball therein may have a rolling action and a left and right thrust action. Although configured as shown in Figure 3, the retainer 54 is configured to hold the bearing 51.
한편, 페달축(11)은 그 외주의 일부분은 클러치베어링(31)이 작동될 수 있도록 축지름을 굵게 하고 다른 부분은 클러치베어링(31)은 작동되지 않고 베어링(51)만 구름운동을 할 수 있도록 축지름을 가늘게 형성하여 필요에 따라 클러치베어링(31)의 작동을 제어할 수 있도록 하였다.On the other hand, the pedal shaft 11 is a portion of the outer circumference so that the clutch bearing 31 can be operated to thicken the shaft diameter and the other portion of the clutch bearing 31 is not operated, only the bearing 51 can perform the rolling motion Shaft diameter was formed so as to be able to control the operation of the clutch bearing 31 as needed.
작동원리를 설명하자면, 평상시에는 페달축(11)의 스프링고정턱(12)에 걸리게 설치한 스프링(42)의 반발력에 의해 페달몸체 안에 설비한 클러치베어링(31)이 테이퍼 가공면(13) 우측의 축지름이 작아진 페달축(11) 부분으로 밀려나 있기 때문에 클러치베어링(31)으로 힘의 전달이 되지 않는다To explain the principle of operation, normally, the clutch bearing 31 mounted in the pedal body by the repulsive force of the spring 42 mounted on the spring fixing jaw 12 of the pedal shaft 11 is the right side of the tapered surface 13. Since the shaft diameter of the shaft is pushed to the smaller portion of the pedal shaft 11, the force is not transmitted to the clutch bearing 31.
따라서 클러치베어링(31)이 작동되지 않아 베어링(51)의 구름작용으로 페달발판이 발의 전후 양방향으로 자유롭게 페달축 중심으로 회전을 한다.Therefore, the clutch bearing 31 is not operated so that the pedal footrest rotates freely around the pedal shaft in both directions before and after the foot due to the rolling action of the bearing 51.
이렇게 종래의 일반페달처럼 사용하던 중에 오르막길이나 맞바람을 만나면, 좀 더 수월하게 주행하기 위해 클러치베어링(31)을 작동시켜야 할 필요가 있을 경우에는 도 2a 에 도시한 바와 같이, 페달프레임(21)의 상단 가장자리에 돌기한 슬라이딩레버(22)를 안쪽으로 밀쳐서 클러치베어링(31)을 작동시킨다.When the uphill or the upwind is met while using the conventional pedal, it is necessary to operate the clutch bearing 31 in order to travel more easily, as shown in FIG. 2A. The clutch bearing 31 is operated by pushing the sliding lever 22 which protrudes on the upper edge inward.
슬라이딩레버(22)를 안쪽으로 밀치면, 구름작용을 하던 페달 베어링(51)가 스러스트; thrust 작용까지 하여 페달몸체의 슬라이딩을 돕게 되는데, 이때 클러치베어링(31)이 축지름이 큰 안쪽으로 쉽게 밀릴 수 있도록 테이퍼 가공면(13)의 경사각을 최대한 작게 형성하여 클러치베어링(31)의 슬라이딩이 용이하게 한다.When the sliding lever 22 is pushed inward, the pedal bearing 51 which was rolling has thrust; The thrust action helps the sliding of the pedal body. At this time, the inclination angle of the tapered surface 13 is formed to be as small as possible so that the clutch bearing 31 can be easily pushed inward with a large shaft diameter. To facilitate.
안쪽으로 밀린 클러치베어링(31)은 두꺼워진 페달축(11)으로 인해 베어링의 허용공차가 작아지므로 바로 클러치베어링(31)에 힘이 전달되어 이 힘은 페달프레임(21)에 전달된다. 그러면 페달프레임(21)의 자유로운 회전이 억제된다Since the clutch bearing 31 pushed inward has a small tolerance of the bearing due to the thickened pedal shaft 11, a force is directly transmitted to the clutch bearing 31, and this force is transmitted to the pedal frame 21. Then free rotation of the pedal frame 21 is suppressed.
즉, 클러치베어링(31)에 설치된 베어링에 의해 회전은 하되, 강제로 힘을 가하지 않는 한 자유로운 회전이 억제된다. 그러므로 페달발판이 임의로 자유롭게 뒤로 제껴지지 않고 발로 페달발판을 밟은 그 수평상태로 수평 유지하면서 페달이 페달크랭크를 돌리게 된다That is, by the bearing provided in the clutch bearing 31 to rotate, free rotation is suppressed unless a force is applied. Therefore, the pedal turns the pedal crank while keeping the pedal foot horizontal, without being arbitrarily freely backed.
그렇게 되면 발로 밟는 힘이 페달프레임(21)의 앞쪽에 집중적으로 가해지게 된다. 예를 들어 페달이 상부로 올라온 상태인 수직 상태에서 페달이 페달축(11)에서 자유롭게 회전이 되는 상태에서는 발의 가압력이 페달축(11)에 집중되나, 페달이 자유회전하지 않고 수평으로 놓여진 상태에서는 페달의 앞쪽 즉 발가락 앞쪽에 힘이 가해지므로 그 페달축(11)에서 그 전방 앞으로 즉, 발 앞끝 방향으로의 페달 앞쪽에 힘이 가해지므로, 페달축(11)에서 그 페달 앞으로의 길이만큼 모멘트력이 작용하므로, 힘의 사점 위치가 없이 크랭크회전력을 가해줄 수 있는 것이다.Then, the stepping force is intensively applied to the front of the pedal frame 21. For example, in a state in which the pedal is freely rotated on the pedal shaft 11 in a vertical state in which the pedal is raised upward, the pressing force of the foot is concentrated on the pedal shaft 11, but in a state in which the pedal is placed horizontally without free rotation. Since a force is applied to the front of the pedal, that is, to the front of the toe, a force is applied to the front of the pedal in front of the pedal shaft 11, that is, to the front of the pedal in the direction of the front end of the foot, and thus the moment force of the pedal shaft 11 in front of the pedal. Because of this, it is possible to apply the crank rotation power without the dead point position of the force.
또 다른 적용예로, 클러치베어링 홈(18)을 형성한 페달축(11)을 사용한 페달의 구조를 첨부 도면 도 4 및 도 5를 참조하여 설명하자면, 클러치베어링(31)이 작동될 수 없도록 페달축(11)의 일부분에 클러치베어링 홈(18)을 형성하여 클러치베어링 홈(18)에 배치된 클러치베어링(31)의 허용공차가 베어링(51)의 공차보다 크게 하여 베어링(51)만 구름운동을 할 수 있도록 하였다.In another application example, the structure of the pedal using the pedal shaft 11 having the clutch bearing groove 18 will be described with reference to FIGS. 4 and 5, so that the clutch bearing 31 cannot be operated. The clutch bearing groove 18 is formed in a portion of the shaft 11 so that the tolerance of the clutch bearing 31 disposed in the clutch bearing groove 18 is larger than the tolerance of the bearing 51 so that only the bearing 51 rolls. To be able to.
클러치베어링(31)을 작동시켜야 할 필요가 있을 경우에는, 도 6a 및 도 6b 에 도시한 바와 같이, 페달프레임(21)의 상단 가장자리에 돌기한 슬라이딩레버(22)를 안쪽으로 밀쳐서 클러치베어링(31)이 클러치베어링 홈(18)을 벗어나 작동될 수 있도록 하였다.When it is necessary to operate the clutch bearing 31, as shown in Figs. 6a and 6b, the sliding lever 22 protruding on the upper edge of the pedal frame 21 is pushed inward to make the clutch bearing ( 31) can be operated out of the clutch bearing groove (18).
이 방법은 클러치베어링(31)이 페달몸체의 양단에 복수로 되어 있는 장점도 있지만 클러치베어링(31)이 클러치베어링 홈(18)을 벗어날 때 테이퍼 가공면(13)보다 약간 부드럽지 못한 단점은 있으나 작동상 문제될 것은 없다.This method has the advantage that the clutch bearing 31 is plural at both ends of the pedal body, but has a disadvantage that the clutch bearing 31 is slightly softer than the tapered surface 13 when the clutch bearing groove 18 is released. There is nothing wrong with the operation.
본 발명에 의하면, 관성에너지가 없는 상태에서의 사점 구간에서도 일정량의 회전력을 얻게 하여 오르막길 등판 주행 등을 수월하게 하며, 아울러 역페달링도 가능하여 안전 주행을 할 수 있도록 하였고, 제어방식을 간편하게 하여 언제 어떤 상황에서도 한방향클러치베어링을 제어하게 함으로써 페달의 사용효과를 더욱 높였다.According to the present invention, a certain amount of rotational force is obtained even in a dead point section in the absence of inertial energy to facilitate uphill climbing and the like, and reverse pedaling is also possible to allow safe driving, and a convenient control method. In any situation, the one-way clutch bearings can be controlled to enhance the pedal's effectiveness.
