본 고안은 농기계인 트랙터의 내부 엔진 진동방지 장치에 관한 것으로서, 특히 트랙터의 엔진과 샤시 사이에 장치하는 구조가 아니고, 엔진블럭에 볼트로 연결되는 오일섬프 바닥에 일체로 용접고정된 포울상에 일정두께와 자증을 갖는 철판을 상, 하 동작 가능하게 스프링과 함께 탄력 설치하여 엔진의 진동에 의해서 철판이 포올상에서 엔진오일과 함께 진동방향의 반대로 상, 하 동작하여 즉 진동압소버처럼 동작되게 하여 트랙터의 운전시 엔진에서 발생하는 진동을 흡수하므로써 엔진의 진동을 최소한으로 방지하여 줄 수 있도록 한 트랙터의 엔진 진동방지 장치에 관한 것이다.The present invention relates to an internal engine vibration damping device of a tractor, which is a farm machine, and is not particularly structured between the engine and the chassis of the tractor, and is fixed on a sole fixed to the bottom of the oil sump that is bolted to the engine block. Resilient installation of steel plate with thickness and self-elevation with spring to enable the up and down operation, and the steel plate moves up and down in the opposite direction of vibration direction with engine oil by vibrating the engine, so that it works like vibrating pressure absorber. The present invention relates to an engine vibration preventing device of a tractor that can prevent vibration of the engine to a minimum by absorbing vibration generated from the engine during operation of the engine.

일반적으로 농업용 기계인 트랙터는 다른 기계와는 달리 진동발생이 심하고 엔진 자체가 샤시 구조의 형태로 되어 있어 기존 자동차와 같은 엔진의 진동방지 장치가 불가능하였다.In general, a tractor, which is an agricultural machine, unlike other machines, generates a lot of vibration, and the engine itself is in the form of a chassis structure, and thus it is impossible to prevent vibration of an engine like an existing vehicle.

그래서 엔진블럭에 체결 고정되는 엔진 오일섬프내에 진동방지장치를 장착해야 했던 것이다.Therefore, the vibration damping device had to be installed in the engine oil sump that is fastened to the engine block.

따라서 상기와 같은 목적으로 종래에는 제 4 도에서 보는 바와 같이 트랙터의 엔진(a) 크랭크 샤프트(b)의 회전력이 크랭크 샤프트(b) 끝단의 기어(c)와 맞물려지며 동력전달축과 선단에 설치된 또 다른 기어(d)의 맞물린 아이들기어(1)의 맞물림 동작에 의해서 회전이 동력 전달축(e)에 전달된 회전동력은 동력전달축(e)상의 반대편에 설치된 기어(f)에 전달되고 이동력은 다시 맞물려 있는 기어(g)에 전달되면서 회전이 반대방향으로 동작하여 피동축(h)상에 장착된 발란서(k)에 전달된다.Therefore, for the purpose as described above, as shown in FIG. 4, the rotational force of the crankshaft (b) of the engine (a) of the tractor is meshed with the gear (c) at the end of the crankshaft (b) and installed at the power transmission shaft and the tip. The rotational power whose rotation is transmitted to the power transmission shaft e by the engaging operation of the engaged idle gear 1 of another gear d is transmitted to the gear f installed on the opposite side on the power transmission shaft e and moves. The force is transmitted to the gear g, which is engaged again, while the rotation is operated in the opposite direction, to the balancer k mounted on the driven shaft h.

이와 같이 기어비를 조정하여 엔진(a) 크랭트 샤프트(b)의 회전와 피동축(h)상의 발란서(k)회전수가 1:2 정도로 되게 함으로써 4기통엔진의 주진동원인 2차 진동을 상쇄시키므로써 트랙터 엔진 진동 발생을 방지하여 쾌적한 운행을 할 수 있게 하였으나, 이와 같은 종래의 방법은 엔진 크랭크 샤프트에서 기어 배열에 의해서 회전력을 전달받아 편심을 갖는 두 개의 발란서를 엔진크랭크샤프트 회전수 2배로 고속 회전시켜 엔진 회전수 2배의 주파수를 갖는 진동을 발생시키므로써 4기통엔진의 가장 큰 진동원인인 2차 진동에 비해 위상은 180°이고, 크기는 동일한진동이 되어 180°의 위상차로 동일한 양의 진동을 역방향으로 발생시키므로 인해 두 진동은 상쇄되어 없어져 버리면서 엔진의 진동을 방지할 수 있게 되었던 것이다.By adjusting the gear ratio in this way, the rotation of the engine crank shaft b and the rotation speed of the balancer k on the driven shaft h are about 1: 2, thereby canceling the secondary vibration which is the main vibration source of the four-cylinder engine. The tractor engine prevents vibration and makes it possible to operate comfortably. However, the conventional method is to rotate the two balancers having an eccentricity at high speed by doubling the engine crankshaft rotation speed by receiving rotational force by the gear arrangement in the engine crankshaft. By generating vibrations with a frequency of twice the engine speed, the phase is 180 ° compared to the secondary vibration, the largest source of vibration of the four-cylinder engine, and the magnitude is the same. Due to the reverse direction, the two vibrations canceled out and prevented the engine from vibrating.

그러나 이 같은 종래의 방법은 샤프트상의 기어배열 등으로 인하여 그 구조가 복잡하며, 부품수가 많아 제조원가를 상승시킬 뿐 아니라, 제조공정도 복잡하여 생산성이 저하되며, 복잡한 구조로 되어 있어 이에 따른 엔진의 부피와 무게가 커져 보다 컴팩트한 기계를 생산하기가 어려웠던 것이다.However, such a conventional method has a complicated structure due to the arrangement of the gears on the shaft, and increases the manufacturing cost due to the large number of parts. And the increased weight made it more difficult to produce more compact machines.

본 고안은 상기와 같은 종래의 문제점을 보완하고져 트랙터의 엔진블럭에 체결 고정되는 엔진 오일섬프내에 일체로 용접 설치된 4개의 포올상에 상, 하 유동하며 일정두께와 자증을 갖는 철판을 붓싱(Bushing)과 함께 스프링으로 오일내에 탄력 설치한 간단한 구조로 트랙터의 엔진진동과 반대방향으로 철판이 오일과 함께 상, 하동작하여 엔진의 진동을 흡수 방지할 수 있도록 한 것으로서, 이하 본 고안을 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention complements the above-mentioned problems and bushes up and down the steel plates having a certain thickness and self-flow up and down on four poles installed integrally welded in an engine oil sump fastened and fixed to the engine block of the tractor. With a simple structure that is elastically installed in the oil with a spring to prevent the steel plate to move up and down with the oil in the opposite direction to the engine vibration of the tractor to absorb the vibration of the engine, the present invention is attached to the accompanying drawings When described in detail as follows.

본 고안의 구성을 보면 제 1 도와 제 2 도에서 보는 바와 같이, 통상적인 트랙터의 엔진블럭(2)에 체결 고정되어 있는 오일섬프(3) 내부면 바닥에 4개의 포울(4)(4')(4")(4"')을 일체로 용접 고정시키고, 이 포울(4)(4')(4")(4"')상에는 어느정도 질량(무게)가 면적을 갖는 상, 하유동판(5)을 상, 하 동작 가능케 하부와 상부에 스프링(6)(6')으로 탄력 설치하고, 포울(4)(4')(4")(4"')과 유동판(5) 사이에는 동작시 조기 마모 방지를 위한 붓싱(7)이 각각에 삽입 설치되며, 또한 포울(4)(4')(4")(4"')상에 스프링(6)(6')으로 탄력설치된 유동판(5)의 이탈을 방지하기 위하여 포울(4)(4')(4")(4"')상단에는 헤드볼트(8)를 체결 고정시켜 진동압소버 역할을 하도록 구성되었고, 오일섬프(3)내에는 오일(O)이 가득 충진되어 있어 오일 점도와 유동판(5) 표면에 의해서 댐퍼(damper)역할을 하게 하여 더욱 진동 흡수 효과를 높일 수 있게 조립 구성된 것이다.In the construction of the present invention, as shown in FIG. 1 and FIG. 2, four poles (4) (4 ') at the bottom of the inner surface of the oil sump (3) fastened and fixed to the engine block (2) of a conventional tractor. (4 ") (4" ') are integrally welded and fixed, and the upper and lower flow plates (5) which have a certain mass (weight) on this foam (4) (4') (4 ", 4" '). ) Is elastically installed at the lower and upper portions with springs 6 and 6 ', and is operated between the poles 4, 4', 4 ", 4" 'and the fluid plate 5 Bushings (7) are inserted in each to prevent premature wear at the same time, and also flow plates resiliently installed with springs (6) (6 ') on the poles (4) (4') (4 ") (4" '). In order to prevent the separation of (5), the head bolt 8 is fastened and fixed to the top of the poles 4, 4 ', 4 ", 4"', and acts as a vibration pressure absorber. ) Is filled with oil (O), which acts as a damper by the oil viscosity and the surface of the flow plate (5). It is assembled to increase the vibration absorption effect.

이상과 같이 조립 구성된 본 고안의 작용 효과를 진동압소버에 대비하여 상세히 설명하면 다음과 같다.When described in detail in preparation for the vibration pressure absorber effect of the present invention is configured as described above are as follows.

제 3a, b 도에서 보는 바와 같이 진동압소버(A)는 질량(M) 스프링(S) 댐퍼(D)의 조합이 진동압소버(A)의 3대 요소가 된다.As shown in Figs. 3A and 3B, the combination of the mass (M) spring (S) damper (D) is the three elements of the vibration absorber (A).

이때 외부에서 작용하는 힘을 F라 할 때 트랙터의 엔진블럭(2)에 작용하는 2차 진동에 의한 상, 하로 작용하는 힘이라고 볼 수 있다.At this time, when the force acting on the outside F can be seen as a force acting up and down by the secondary vibration acting on the engine block (2) of the tractor.

또한 질량(M)은 본 고안의 포울(4)(4')(4")(4"')상에 스프링(6)(6')으로 탄력 설치된 유동판(5)이고, 스프링(S)은 본 고안의 유동판(5) 상, 하에 설치된 스프링(6)(6')이라 하면 댐퍼(D)는 본 고안의 오일섬프(3)에 가득차 있는 오일(O) 점도와 유동판(5)의 표면적 마찰에 의해 결정되는 값이라고 할 수 있다.In addition, the mass (M) is the flow plate (5) elastically installed with springs 6, 6 'on the soles 4, 4', 4 ", 4" 'of the present invention, and the spring S When the spring (6) (6 ') is installed on the upper and lower flow plate (5) of the present invention, the damper (D) is the oil (O) viscosity and the flow plate (5) filled in the oil sump (3) of the present invention It can be said that the value is determined by the surface area friction of.

따라서 트랙터의 운전시 엔진블럭(2)에 작용하는 2차 진동을 오일섬프(3) 내의 포울(4)(4')(4")(4"')상에 스프링(6)(6')으로 탄력 설치된 유동판(5)에 작용하게 된다.Thus, the secondary vibrations acting on the engine block 2 during operation of the tractor are applied to the springs 6, 6 'on the soles 4, 4', 4 ", 4" 'in the oil sump 3. It acts on the fluidized plate 5 elastically installed.

이때 유동판(5)에 도달한 진동에 의해 유동판(5)이 상측으로 움직일 경우에는 스프링(6)이 압축되고 유동판(5)이 하측으로 움직일 경우에는 스프링(6')이 압축동작되면서, 유동판(5)의 상, 하 동작과 함께 스프링(6)(6')은 교번으로 압축하여 엔진블럭에 발생된 2차 진동방향과 역으로 유동판(5)이 동작하면서 진동을 흡수, 완충시키게 된다.At this time, when the fluid plate 5 moves upward due to the vibration that reaches the fluid plate 5, the spring 6 is compressed, and when the fluid plate 5 moves downward, the spring 6 'is compressed. The springs 6 and 6 'are alternately compressed with the up and down motions of the flow plate 5 to absorb the vibration while the flow plate 5 operates in the reverse direction of the secondary vibration generated in the engine block. Will be buffered.

이러한 진동흡수 작용은 유동판(5)의 표면적과 오일섬프(3)내의 적당한 오일(O) 점도와의 마찰력에 의해 더욱 증대되어지게 되고, 또한 유동판(5)과 스프링(6)(6')은 점성과 함께 어느정도 신축성을 갖는 오일(O)속에 내장되어 있으므로 소음이 방지됨과 동시에 진동의 흡수가 증대되게 되는 것이다.This vibration absorption action is further increased by the frictional force between the surface area of the flow plate 5 and the appropriate viscosity of the oil (O) in the oil sump (3), and also the flow plate (5) and the spring (6) (6 '). ) Is embedded in the oil (O) having a certain elasticity with viscosity, so that the noise is prevented and the absorption of vibration is increased.

환원하면 엔진의 2차 진동 발생량만큼 유동판(5)이 반대방향으로 스프링(6)(6')과 함께 상, 하 동작되나 이들은 점도를 갖는 오일(O)속에 내장되어 있어 작동음이 오일(O) 점성으로 차단될 뿐 아니라 오일(O)과의 마찰력으로 소음없이 진동을 흡수할 수 있게 되는 것이다.When it is reduced, the flow plate 5 is operated up and down together with the springs 6 and 6 'in the opposite direction by the second vibration generation amount of the engine, but they are built into the oil O having a viscosity, so the operation sound O) Not only is it blocked by viscosity, but it can also absorb vibration without noise due to friction with oil (O).

그러므로 진동 압소버(A)에서 작용하는 힘 F를 스프링(S)과 댐퍼(D) 그리고 질량(M)의 적정한 배합에 따라 힘 F를 감소시켜 주듯이 트랙터의 운전시 엔진블럭에 작용하는 2차 진동을 오일섬프(3)내에 설치된 유동판(5)과 스프링(6)(6') 및 유동판(5)과 오일(O) 점도간의 마찰력으로 감소시켜 주게 되므로 종래처럼 그 구조가 복잡하지 않으면서 4기통 엔진에서 가장 문제시 되는 2차 진동을 감소시켜 트랙터의 쾌적한 운전이 가능할 뿐 아니라, 그 구조가 간단하고, 부품수가 적어 제조공정이 손쉽고 이에 따라 제조원가를 절감시킬 수 있으며, 또한 장치가 컴팩트하므로 엔진 자체도 소형화 할 수 있는 효과도 얻고자 한 것이다.Therefore, as the force F acting on the vibration absorber (A) decreases the force F according to the proper combination of the spring (S), the damper (D) and the mass (M), the secondary vibration acting on the engine block during operation of the tractor. Is reduced by the frictional force between the fluidized plate 5 and the springs 6 and 6 'installed in the oil sump 3 and the viscosity between the fluidized plate 5 and the oil O. Thus, the structure is not complicated. It reduces the secondary vibration, which is the most problematic in the four-cylinder engine, to enable the tractor to operate comfortably, and its structure is simple, the number of parts is easy, so the manufacturing process is easy and the manufacturing cost is reduced, and the device is compact. The engine itself could also be miniaturized.
