Description

삼륜차의 전륜완충장치(前輪緩衝裝置)Front wheel shock absorber of tricycle

제1도는 본 고안의 설치 상태 예시도1 is an illustration of the installation state of the present invention

제2도는 제1도의 A-A선 확대단면도2 is an enlarged cross-sectional view taken along the line A-A of FIG.

제3도는 동상이 요부 확대 측면도3 is a side view enlarged statue

본 고안은 농춘에서 주로 농산물 등을 운반하는데 사용하는 삼륜에 있어서 완충부와 전륜을 지지하는 지지간을 별개로 설치하되 작동로드 하단과 지지간 하단은 전륜의 축에 축설된형작동편에 각각 축설시켜 상호 유기적인 작동으로 전륜의 축격을 오나화시켜줄 뿐 아니라 완충부의 기계적 마모를 치대한 방지하고, 차체에 축착된 지지간에 의하여 완충부와 전륜을 지지하여 주므로 차체와 전륜의 중심이 항상 일치되게 하여 차체의 편심하중에 의한 마모를 억제하고 항상 안정된 마음으로 작업능울을 배가할 수 있는 삼륜차의 전륜 완충장치에 관한 것이다. 종래 삼륜차의 전륜 완충장치는 피스톤형식 완충기로서 즉 직경이 상이한 파이프를 상호 삽입시미고 그 내측 또 외측에 완충스프링을 설치하되 상부파이프의상단은 차체와 일체로된 지지체와 일체로 고정하고 하부 파이프의 하단을 직접 전륜축에 지지케 하므로서 항상 중압감에 의하여 작동이 되므로 각 파이프가 마모되고 차체와 전륜축의 중심이 비틀어질 우려가 많아 편심하중에 의한 차체의 마모와 사고에 대한 불안감이 따랐으며 또한 각 파이프간에 탄지된 완충스프링의 탄력에 의하여 적은 충격에도 차체가 여러번 진동하기 때문에 작업자로 하여금 피로를 쉬 가져오게 하여 작업능율을 저하시키는 큰 요인이 되었던 것이다.In the present design, in the three wheels used mainly for transporting agricultural products in Nongchun, the buffer rod and the support for supporting the front wheel are separately installed, but the lower part of the working rod and the lower end of the support are installed on the shaft of the front wheel. It is built on each of the mold pieces to mutually organic operation, which not only makes the front wheel axially on and off, but also prevents the mechanical wear of the shock absorbing part greatly, and supports the shock absorbing part and the front wheel by the support between the car body. The present invention relates to a front wheel shock absorber of a three-wheeled vehicle capable of aligning the center of gravity at all times to suppress wear due to eccentric load of the vehicle body and to double the work capacity with a stable mind at all times. The front wheel shock absorber of the conventional tricycle is a piston type shock absorber, that is, inserts pipes of different diameters into each other, and installs shock absorbing springs inside and outside thereof, and the upper end of the upper pipe is fixed integrally with the support integrated with the vehicle body, Since the lower part is directly supported by the front axle, it is always operated by a heavy pressure, so each pipe is worn and the center of the body and the front axle may be twisted.Therefore, there is anxiety about the wear and accident of the body due to the eccentric load. Due to the elasticity of the shock springs in the liver, the vehicle body vibrates many times even with a small impact, which makes it easy for workers to reduce fatigue.

본 고안은 전륜에 충격이 오면 완충부에 의하여 쉽게 완충되면서진동의 빈도가 극히 적으며 또한 지지간이 전륜을 지지하기 때문에 차체와 전륜과의 중심이 비틀어질 염려가 전혀 없는 것으로 이를 첨부도면에 의거 설명하면 다음과 같다.The present invention is easily cushioned by the shock absorber when the shock comes to the front wheel, and the frequency of vibration is extremely small. Is as follows.

1은 지지체(2)하부의 회전편(3)에 축설된 지지간에 이 지지간(1)상부는 고정부(4)하부는형작동편(5)에 각각 축설하였다.1 is between the support which was built up in the rotating piece 3 of the lower part of the support body 2, This upper support part 1 upper part is a fixed part 4 lower part. It was built up in the mold operation piece 5, respectively.

6은 고정부(4)의 고정홈(7)과 감합관(8)(8a)에 끼워진 작동로드인데이 작동로드 (6)상부에는 삽입관(9)(9a)과 주삽입간(10)이 돌설되었으며 작동로드(6)하단은형 작도연(5)에 축설되어 있다. 11는 감합관(8)(8a)과 삽입관(9)(9a)간에 탄설된 완충스프링이다.6 is an operation rod fitted in the fixing groove 7 and the fitting tube 8, 8a of the fixing portion 4, the insertion tube (9) (9a) and the main insertion section (10) above the operation rod (6) The bottom of the operating rod (6) It is built in the mold drawing lead 5. 11 is a shock absorbing spring installed between the fitting tube 8, 8a and the insertion tube 9, 9a.

12는 공지의 전륜이고, 13은 조향편이며, 14는 핸들이다.12 is a known front wheel, 13 is a steering piece, and 14 is a handle.

15는 전륜(12)의 축이다.15 is the axis of the front wheel 12.

이와 같이 구성된 본 고안의 작동효과를 설명하면 다음과 같다.Referring to the operation effect of the present invention configured as described above are as follows.

먼저 제2도 및 제3도에 접선으로 표시한 바와같이 지반의 굴곡에 의하여 전륜에 충격이 오면 지지간(1)과형 작동편(5)을 연결한 축을 중심으로 전륜(12)의 축(15)이 약간 위로 상승하는 동시에 작동로드(6)와 연결된 형 작동편(5)의 타측이 상승하므로 자연 작동로드(6)과 상승하면시 고정부(4)의 고정홈(7)과 감합관(8)(8a)내로 완충로드(6)의 주삽입간(10)과 삽입간(9)(9a)이 들어가면서 완충스프링 (11)은 압축되어 그 충격이 완화되는 것이다 .First, as shown by the tangential lines in Figs. 2 and 3, when the front wheels are impacted by the bending of the ground, the support section 1 and As the shaft 15 of the front wheel 12 rises slightly around the shaft connecting the mold operating piece 5 and the other side of the mold operating piece 5 connected with the actuating rod 6 rises, the natural actuating rod 6 ), And the main insertion section 10 and insertion section 9 and 9a of the buffer rod 6 enter the fixing groove 7 and the fitting tube 8 and 8a of the fixing section 4 when they rise. The spring 11 is compressed so that its impact is alleviated.

따라서 충격이 일단 완화되면 그 완충스프링(11)의 탄성에 의해 작동로드(6)가 하강하므로 다시 지지간(1)의 하단축을 중심으로 전륜(12)의 축(15)이 원위치로 내려오게 되는 동시에 전륜(12)이 앞쪽으로 약간 숙여지므로 종래의 완충장치에 비해전륜(12) 및 차체의 진동이 거의 없게되는 것이다. 그리고 지지간(1)의 중간이 지지체(2)하부의 회전편(3)에 축설되어 있고 지지간(1)상단은 고정부(4)에 하단은형 작동편(5)에 각각 축설되어 있어 전륜(12)을 직접 지지하고 있는 것은 지지간(1)이 되는 것이므로 전륜(12)의심한 충격에도 전륜축(15)과 차체의 중심이 비틀어진 우려가 전혀 없으며 특히 조향시에도 핸들(14)과 조향편 (13), 고정부(4), 지지체(2)하부의 회전편(3)이 각각 일체로 되어 있어 매우 안정된 상태로 핸들(14)을 조작할 수 있는 것이다. 상술한 바와 같이 본 고안은 지지간(1)에 의하여 전륜(12)을 지지토록 함과 동시에 고정부(4) 및 작동로드(6)을 지지하고 있되 지지간(1)의 하단과 작동로드(6)의 하단을 각각 전륜홈(15)에 축설되 있는형 작동편(5)에 각각 축설시켜 상호 유기적인 작동으로 전륜(12)의 충격을 완화하고 전륜축(15)의 중심을 고정시켜 주게 하므로서 차체와 전륜(12)의 중심이 항상 일치되게 하여 안정된 상태에서 운전을 할 수가 있으므로 작업능률을 배가 할 수 있는 효과가 있다.Therefore, once the shock is alleviated, the rod 6 is lowered by the elasticity of the shock absorbing spring 11, so that the shaft 15 of the front wheel 12 is lowered back to its original position with respect to the lower axis of the support section 1 again. At the same time, the front wheel 12 is slightly leaned forward so that the vibration of the front wheel 12 and the vehicle body is substantially less than that of the conventional shock absorber. The middle of the support section 1 is arranged on the rotating piece 3 under the support 2, and the upper end of the support section 1 is fixed to the fixing section 4, Since the front wheel 12 directly supports the front wheels 12 to be built in each of the mold operating pieces 5, it is the support section 1, so that the center of the front wheel shaft 15 and the vehicle body are twisted in spite of the severe impact of the front wheels 12. In particular, the steering wheel 14, the steering piece 13, the fixing part 4, and the rotating piece 3 under the support part 2 are integral with each other even during steering. It can be manipulated. As described above, the present invention supports the front wheels 12 by the support bar 1, and simultaneously supports the fixing unit 4 and the operation rod 6, but the lower end of the support bar 1 and the operation rod ( 6) the lower end of each of which is built in the front wheel groove (15) It is built on each of the mold operating pieces 5 to mitigate the impact of the front wheels 12 and to fix the center of the front wheel shaft 15 by mutually organic operation so that the centers of the vehicle body and the front wheels 12 always coincide. The operation can be performed in the state, so the work efficiency can be doubled.
