서행용 이륜차의 구동전달장치Drive Transmission Device for Slow Speed Motorcycle
Description
본 고안은 서행용 이륜차의 구동전달장치에 관한것으로써, 보다 상세하게는 소형엔진에 의하여 회전구동력을 전달받은 회전구동전달축이 휘일타이어의 트래드 일측면을 가압접촉하여 그 가압접촉력에 의해 주행을 취하는 서행용 이륜차의 구동 전달장치에 관한 것이다.The present invention relates to a drive transmission device for a slow motion two-wheeled vehicle, and more particularly, a rotation drive transmission shaft which receives rotation driving force by a small engine presses one side of the tread of the wheel tire and travels by the pressure contact force. It relates to a drive transmission device for a slow riding two-wheeled vehicle.
일반적으로 이륜차는 엔진의 회전구동력을 직접적으로 전달받아 주형을 취하는 모터 사이클이나 발판상에서 직립의 상태로 서서 근거리 주행을 취하는 간접전달방식에 의한 서행용 이륜차(소형 모터 사이클으로 통칭하기도 함) 등이 있다.In general, two-wheeled vehicles include a motorcycle that receives direct rotational driving force of the engine and a slow-moving two-wheeled vehicle (sometimes referred to as a small motor cycle) by an indirect transmission method that takes a short distance while standing upright on a footboard. .
본 고안은 이러한 서행용 이륜차의 구동전달장치는 첨부한 도면 제1도 내지 제2도에 도시하고 있는 바와 같이 엔진(E)의 작동에 의해 회전구동력을 전달받은 회전구동전달축(1)의 전달봉(3)이 휘일타이어(2)의 일측 트래드면(5)을 가압하는 상태로 설치되어져서 회전구동전달축(1)의 회전구동력이 전달봉(3)을 통해 휘일타이어(2)를 간접회전구동시키도록 되어 있다.The present invention is a drive transmission device for such a slow driving two-wheeled vehicle as shown in the accompanying drawings 1 to 2 transfer of the rotation drive transmission shaft (1) received the rotational driving force by the operation of the engine (E). The rod 3 is installed to press the one side tread surface 5 of the wheel tire 2 so that the rotational driving force of the rotation drive transmission shaft 1 indirectly moves the wheel tire 2 through the transmission rod 3. It is designed to rotate.
이러한 종래의 서행용 이륜차의 구동전달방식은 전달봉(3)이 일직선의 형태로 형성되어 있기 때문에 완만한 형태로 형성된 휘일타이어(2) 트래드면(5)에 극히 일부분 만이 접촉되어 가압하게 되므로 전달봉(3)의 회전구동력이 휘일타이어(2)의 트래드면(5)에 접촉하는 면적이 지극히 작아 슬립현상이 발생하여 완전한 구동전달이 제대로 이루어지지 아니하고, 특히 장기간 사용하여 휘일타이어(2)의 트래드면(5)에만 마모가 발생함에도 불구하고 휘일타이어(2)를 교체해야 하는 등의 문제점이 있었다.In the drive transmission method of the conventional slow-wheeled two-wheeled vehicle, since the transmission rods 3 are formed in a straight line, only a part of the wheel tires 2 and the tread surface 5 formed in a gentle shape contact and pressurize. The rotational driving force of the rod 3 is extremely small in contact with the tread surface 5 of the wheel tire 2, so that slippage occurs and complete drive transmission is not performed properly. Despite wear on only the tread surface 5, there was a problem that the wheel tire 2 had to be replaced.
이에 본 고안은 상기와 같은 문제점을 고려하여 안출된 것으로서, 그 목적은 엔진의 작동에 의해 회전구동력을 전달받은 회전구동전달축의 전달봉이 휘일타이어의 트래드면에 가압접촉되어 일정한 시간동안 사용되어 휘일타이어의 트래드면에 마모가 발생하여 전달봉에 휘일타이어의 트래드면과의 가압접촉력이 떨어져도 휘일타이어를 수동으로 이동시켜 전달봉에 항상 휘일타이어의 트래드면을 가압접촉될 수 있도록 하고, 또한 회전구동전달축의 전달봉이 휘일타이어의 트래드면에 가압접촉하는 가압접촉면적을 극대히하여 전달봉의 회전구동력을 휘일타이어에 완벽하게 전달하고자 하는데 있다.The present invention is conceived in view of the above problems, the purpose is that the transmission rod of the rotary drive transmission shaft received the rotary driving force by the operation of the engine is pressed in contact with the tread surface of the wheel tire used for a certain time Even if abrasion occurs on the tread surface of the transmission rod and the pressure contact force with the tread surface of the wheel tire drops, the wheel tire is moved manually so that the tread surface of the wheel tire is in pressure contact with the transmission rod at all times. The transmission rod of the shaft maximizes the pressure contact area that is in pressure contact with the tread surface of the wheel tire, so as to completely transmit the rotation driving force of the transmission rod to the wheel tire.

커버(4)에 설치되어 엔진(E)의 회전구동력을 전달받아 회전구동하는 회전구동전달축(1)의 전달봉(3)에 휘일타이어(2) 트래드면(5)을 가압접촉하여 휘일타이어(2)를 회전구동하여 주행하는 서행용 이륜차의 구동전달장치에 있어서, 상기 커버(4)의 양측면에 활형장공(10), 조정돌기(11) 및 축공(12)을 각각 형성하고, 상기 커버(4)의 외측면에는 손잡이(14)에 연결된 한 쌍의 조절링크(15)가 각각 설치되어지고, 상기 조절링크(15)에는 상기 활형장공(10)에 대응하는 고정공(16),상기 축공(12)과 대응하는 축공(17) 및 상기 조정돌기(11)과 대응하는 위치에 다수의 조절공(13)을 각각 형성하고, 상기 활형장공(10)과 고정공(16)을 통해 상기 휘일타이어(2)를 회전가능하게 결합하고 있는 고정축(18)이 삽입되어 그 타단에서 너트(19)로 체결하여 상기 커버(4)와 조절링크(15)를 결합하고, 상기 축공(12)과 축공(17)을 통해 체결구(20)로 회동가능하게 체결하여 상기 조절링크(15)가 상기 커버(4)에서 회동가능하고, 상기 조정돌기(11)에는 다수의 조절공(13)이 삽입되는 위치에 따라 체결구(20)를 축지점으로 이동하여 상기 커버(4)에서 위치하는 조절링크(15)의 위치가 변경되는 구조로 이루어진다.The tire tire is installed in the cover 4 by pressure-contacting the wheel tire 2 and the tread surface 5 to the transmission rod 3 of the rotation drive transmission shaft 1 that receives the rotational driving force of the engine E to rotate. In the drive transmission device of a slow two-wheeled vehicle for driving by rotating (2), the long side holes 10, the adjustment projections 11 and the shaft hole 12 are formed on both sides of the cover 4, respectively, and the cover The outer side of the (4) is provided with a pair of control links 15 connected to the handle 14, respectively, the control link 15 is a fixing hole 16 corresponding to the bow hole 10, A plurality of adjustment holes 13 are formed at positions corresponding to the shaft holes 12 and the shaft holes 17 and the adjustment protrusions 11, respectively, and the through the long holes 10 and the fixing holes 16. The fixed shaft 18 rotatably coupling the wheel tire 2 is inserted and fastened with a nut 19 at the other end thereof to couple the cover 4 and the adjustment link 15 to each other. Highly rotatably fastening to the fastener 20 through the shaft hole 12 and the shaft hole 17, the control link 15 is rotatable in the cover (4), the adjustment projection (11) a number of According to the position of the adjustment hole 13 is inserted into the fastener 20 to the axial point is made of a structure in which the position of the control link 15 located in the cover (4) is changed.
이러한 구조를 갖는 본 고안의 작동을 구체적으로 살펴보기로 한다.The operation of the present invention having such a structure will be described in detail.
엔진(E)의 작동에 의해 회전구동력을 전달받은 회전구동전달축(1)의 전달봉(3)이 휘일타이어(2)의 일측 트래드면(5)을 가압하는 상태로 설치되어져서 회전구동전달축(1)의 회전구동력이 전달봉(3)을 통해 휘일타이어(2)를 간접회전구동 시키도록 되어 있기 때문에 장기간 사용을 하게 되면 절단봉(3)과 트래드면(5)과의 마찰로 인해 트래드면(6)에 마모가 발생하게 된다.The transmission rod 3 of the rotation drive transmission shaft 1, which receives the rotation driving force by the operation of the engine E, is installed in a state of pressing the tread surface 5 on one side of the wheel tire 2 to transmit the rotation drive. Since the rotational driving force of the shaft 1 is to indirectly drive the wheel tire 2 through the transmission rod 3, when it is used for a long time, the friction between the cutting rod 3 and the tread surface 5 may occur. Wear occurs on the tread surface 6.
이러한 이유로 인해 전달봉(3)이 트래드면(5)과의 가압접촉력이 떨어지게되게 되므로 전달봉(3)의 회전구동력이 트래드면(5)에 전달되지 않을 뿐만 아니라 전달된다고 하여도 슬립현상이 발생하여 휘일타이어(2)에 주행력이 떨어지게 된다.For this reason, since the pressure contact force with the tread surface 5 is lowered from the transfer rod 3, the rotational driving force of the transfer rod 3 is not only transmitted to the tread surface 5, but slipping occurs even if it is transmitted. As a result, the driving force falls on the wheel tire 2.
이러한 현상이 발생하게 되면 손잡이(14)를 잡고 강제로 상승하는 이동을 취하여 준다.If this happens, grab the handle (14) and takes a forcible movement.
이러한 상태가 되면 조절링크(15)가 상승하는 것이 되므로 상기 조절링크(15)의 고정공(16)에 내삽입된 고정축(18)이 커버(4)에 형성된 활형장공(10)을 따라 체결구(20)을 축점으로 하여 상승하는 이동을 취하게 된다.In this state, the adjustment link 15 is raised, so that the fixed shaft 18 inserted into the fixing hole 16 of the control link 15 is fastened along the bow hole 10 formed in the cover 4. The ascending movement is taken with the sphere 20 as the axial point.
이때, 상기의 고정돌기(11)에 삽입된 어느 조절공(13)은 상기 고정돌기(11)에서 강제로 이탈하여 조절링크(15)의 위치변경된 위치에 있는 조절공(13)이 상기 고정돌기(11)에 삽입고정 된다.At this time, any adjustment hole 13 inserted into the fixing protrusion 11 is forcibly released from the fixing protrusion 11 so that the adjusting hole 13 at the changed position of the adjusting link 15 is the fixed protrusion. Inserted into (11) and fixed.
이러한 상태는 상기 고정축(18)상에 회전가능하게 결합된 휘일타이어(2)가 고정축(18)을 따라 상승 이동하는 것이 되므로 결국 상기한 바와 같이 휘일타이어(2)의 트래드면(5)에 마모가 발생하여도 상기의 트래드면(5)이 전달봉(3)에 가압접촉이 이루어지게 된다.In this state, since the wheel tire 2 rotatably coupled to the fixed shaft 18 moves upward along the fixed shaft 18, the tread surface 5 of the wheel tire 2 is eventually formed as described above. Even if abrasion occurs in the tread surface 5 is a pressure contact to the transfer rod (3).
이러한 작동에 의해 엔진(E)의 작동에 의해 회전구동력을 전달받은 회전구동전달축(1)의 전달봉(3)이 휘일타이어(2)의 일측 트래드면(5)에 회전구동력을 전달하게 할 수 있게 된다.By this operation, the transmission rod 3 of the rotational drive transmission shaft 1, which has received the rotational driving force by the operation of the engine E, can transmit the rotational driving force to one side tread surface 5 of the wheel tire 2. It becomes possible.
따라서 휘일타이어(2)에는 주행이 발생하게 된다.Therefore, the wheel tire 2 is driven to travel.
이러한 상태에서 일정기간 사용한 후에 다시 트래드면(5)에 재마모가 발생하여 다시 전달봉(3)의 회전구동력이 트래드면(5)에 전달되지 않게 되면 다시 상기한 방법에 의해 휘일타이어(2)를 상승시켜 트래드면(5)을 다시 전달봉(3)에 가압접촉시켜 주면 될 것이다.In this state, after a certain period of time, again wear occurs on the tread surface (5) and again the rotational driving force of the transfer rod (3) is not transmitted to the tread surface (5) again the tire tire by the above-described method By raising the tread surface 5 will be in pressure contact with the transfer rod (3) again.
한편, 종래에는 첨부한 도면 제2도에 도시하고 있는 바와 같이, 상기한 전달봉(3)이 일직선의 형태로 형성되어 있기 때문에 완만한 형태로 형성된 휘일타이어(2) 트래드면(5)에 극히 일부분 만이 접촉되어 가압하게 되므로 전달봉(3)의 회전구동력이 휘일타이어(2)의 트래드면(5)에 접촉하는 면적이 지극히 작아 슬립현상이 발생하여 완전한 구동전달이 제대로 이루어지지 아니하고, 특히 장기간 사용하여 휘일타이어(2)의 트래드면(5)에만 마모가 발생함에도 불구하고 휘일타이어(2)를 교체해야 하는 등의 문제점이 있었다.On the other hand, conventionally, as shown in FIG. 2 of the accompanying drawings, since the transmission rod 3 is formed in a straight line shape, the tread surface 5 of the wheel tire 2 formed in a gentle shape is extremely Since only a part is in contact and pressurized, the area where the rotational driving force of the transmission rod 3 is in contact with the tread surface 5 of the wheel tire 2 is extremely small, so that slip phenomenon occurs and complete drive transmission is not properly performed. In spite of abrasion occurring only in the tread surface 5 of the wheel tire 2, there was a problem that the wheel tire 2 had to be replaced.
이러한 문제점을 해결하기 위하여 회전구동전달축(1)의 전달봉(3) 원주면 일정구간상에 활형요홈(40)을 형성하여 상기 활형요홈(40)이 휘일타이어(2)의 완만한 형태의 트래드면(5)에 가압접촉되도록 하여 가압접촉면적을 극대히 하는 구조로 이루어 준다.In order to solve this problem, the slide groove 40 is formed on a certain section of the circumferential surface of the transmission rod 3 of the rotary drive transmission shaft 1 so that the slide groove 40 has a smooth shape of the wheel tire 2. Pressurized contact with the tread surface 5 is made in a structure to maximize the pressure contact area.
이러한 상태는 전달봉(3)상에 형성된 활형요홈(40)이 휘일타이어(2)의 완만한 트래드면(5)에 활형의 상태로 가압접촉하고 있으므로 그 가압접촉면적이 확대되게 되어 회전구동전달축(1)의 회전구동력이 전달봉(3)을 통해 휘일타이어(2)에 회전구동력을 완벽하게 전달할 수 있게된다.In this state, since the slide groove 40 formed on the transfer rod 3 is in pressure contact with the smooth tread surface 5 of the wheel tire 2 in a bow state, the pressure contact area is enlarged, and the rotation drive transmission is performed. The rotational driving force of the shaft 1 is able to completely transmit the rotational driving force to the wheel tire 2 through the transmission rod (3).
또한 가압접촉면적의 극대화로 인해 휘일타이어(2)의 트래드면(5)의 전체면적을 통해 마모가 발생하기 때문에 마모율이 떨어지게 된다.In addition, since the wear occurs through the entire area of the tread surface 5 of the wheel tire 2 due to the maximization of the pressure contact area, the wear rate is lowered.
이상에서 살펴본 바와 같이 본 고안에 따른 서행용 이륜차의 구동전달장치는, 엔진의 작동에 의해 회전구동력을 전달받은 회전구동전달축의 전달봉이 휘일타이어의 트래드면에 가압 접촉되어 일정한 시간동안 사용되어 휘일타이어의 트래드면에 마모가 발생하여 전달봉에 휘일타이어의 트래드면과의 가압접촉력이 떨어져도 휘일타이어를 수동으로 이동시켜 전달봉에 항상 휘일타이어의 트래드면을 가압접촉될 수 있도록 하여 휘일타이어의 사용기간을 늘리고, 또한 회전구동전달축의 전달봉이 휘일타이어의 트래드면에 가압접촉하는 가압접촉면적을 극대히하여 전달봉의 회전구동력을 휘일타이어에 완벽하게 전달할 수 있는 매우 유용한 고안이다.As described above, in the drive transmission device for a slow motion two-wheeled vehicle according to the present invention, the transmission rod of the rotation drive transmission shaft that receives the rotation driving force by the operation of the engine is pressed against the tread surface of the wheel tire and used for a predetermined time. Even when the contact surface of the tread surface of the tire is worn and the pressure contact force with the tread surface of the wheel tire drops, the wheel tire is moved manually so that the tread surface of the wheel tire can be pressurized with the transmission rod at all times. In addition, the transmission rod of the rotary drive transmission shaft is a very useful design that can completely transmit the rotational driving force of the transmission rod to the wheel tire by maximizing the pressure contact area in pressure contact with the tread surface of the wheel tire.
