겹판 스프링장치{Leafspring apparatus} Leaf spring apparatus

본 발명은 겹판 스프링장치에 관한 것으로서, 더욱 상세하게는 여러개 적층된 스프링판체가 서로 떨어진 상태로 적층되도록 하되 각 스프링판체에 형성된 다수개의 볼록부에 의해 서로 맞닿도록 함으로써, 수직 집중하중을 받을 때 각 볼록부가 휨변형 됨과 동시에 스프링판체의 간격이 좁혀지면서 집중하중이 완화되도록 하여 좁은 공간에서 큰 하중을 받쳐줄 수 있는 겹판 스프링장치에 관한 것이다.The present invention relates to a leaf spring device, and more particularly, a plurality of laminated spring plate body to be laminated in a state separated from each other by a plurality of convex portions formed on each spring plate body, so as to contact each other, when receiving a vertical concentrated load As the convex portion is deflected and at the same time the spacing of the spring plate is narrowed to reduce the concentrated load, the present invention relates to a leaf spring device that can support a large load in a narrow space.

일반적으로 판스프링은 스프링강으로 구성되어 탄성력이 크고 여러장 겹쳐 큰 힘을 받쳐줄 수 있는 겹판 스프링에 주로 사용된다. 겹판 스프링은 주로 자동차의 바퀴측에 설치되어 자동차의 하중을 받쳐주는 것이다.Generally, leaf spring is composed of spring steel, and is mainly used for leaf spring, which has a large elastic force and can support a large force by stacking several sheets. Leaf spring is mainly installed on the wheel side of the car to support the load of the car.

그러나 겹판 스프링은 원호형으로 구부린 띠 모양의 스프링강을 몇 개 겹치고 그 중심을 묶어 고정시킨 뒤 양쪽 끝단에서 하중이 받쳐지도록 한 것이기 때문에 이러한 긴 겹판 스프링은 좁은 공간에서 큰 힘을 받쳐주고자 할 때 사용할 수 없는 단점이 있었다.However, since the leaf spring is made by overlapping several arc-shaped bent strip-shaped spring steels, binding the centers of the springs together, and supporting the loads at both ends, these long leaf springs have a large force in a narrow space. There was a disadvantage that can not be used.

본 발명은 종래의 문제점을 감안하여 개발한 것으로서, 본 발명의 목적은 판스프링을 이용하여 좁은 공간에서 큰 힘을 받쳐줄 수 있도록 하기 위해 판스프링이 서로 떨어지도록 용기 내부에 적층시키되 이들 판스프링에 다수개의 볼록부를 형성시켜 이들 볼록부에 의해 각 판스프링이 맞닿도록 함으로써, 수직 집중하중이 가해지면 각 볼록부가 휨변형되면서 서로 이웃한 판스프링의 간격이 좁혀지고 충격이 완화되도록 한 겹판 스프링장치를 제공함에 있다.The present invention was developed in view of the conventional problems, and an object of the present invention is to stack the leaf springs apart from each other in order to be able to support a large force in a narrow space using a leaf spring, but many of these leaf springs By providing two convex portions so that each leaf spring is abutted by these convex portions, the vertical spring load provides a leaf spring device in which each convex portion is deformed and the gap between adjacent leaf springs is narrowed and shocks are alleviated. Is in.

상기 목적을 달성하기 위하여 본 발명은 스프링강으로 구성된 스프링판체를 여러장 겹쳐 집중하중이 받쳐지도록 한 겹판 스프링장치에 있어서, 상부가 개방되고 개방된 상부로 하중이 가해지는 스프링용기가 구비되고, 스프링용기 내부에는 다수개의 스프링판체가 서로 떨어지도록 적층 구비되며, 각 스프링판체에는 하중을 받으면 휨변형 되는 볼록부가 다수개 구비되고, 각 스프링판체는 이웃한 스프링판체의 볼록부와 맞닿아 서로의 떨어진 간격이 유지되며 각 볼록부는 서로 엇갈리도록 지그재그 형태로 배열 구성되어 있다.In order to achieve the above object, the present invention is a leaf spring device for supporting a concentrated load by overlapping a plurality of spring plate body consisting of a spring steel, the top is open and provided with a spring container is applied to the open top of the spring, the spring Inside the container, a plurality of spring plate bodies are provided so as to be separated from each other, and each spring plate body is provided with a plurality of convex parts that are bent and deformed under load. The convex portions are retained and are arranged in a zigzag form to stagger each other.

이하 본 발명의 바람직한 실시예를 첨부 도면에 따라 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명 겹판 스프링장치의 사시도 이고, 도 2는 본 발명 겹판 스프링장치의 단면도 이다. 본 발명의 겹판 스프링장치는 직육면체의 스프링용기(1)가 구비된다. 용기(1)는 상부가 개방되어 하중이 가해지도록 구성되며 용기(1) 내부에는 다수개의 스프링판체(3)가 내장된다.1 is a perspective view of the leaf spring device of the present invention, Figure 2 is a cross-sectional view of the leaf spring device of the present invention. Leaf spring device of the present invention is provided with a spring container (1) of a rectangular parallelepiped. The container 1 is configured such that an upper portion thereof is opened and a load is applied thereto, and a plurality of spring plate bodies 3 are embedded in the container 1.

스프링판체(3)는 탄성력과 휨변형력이 큰 스프링강으로 구성되어 있으며 스프링판체(3)의 양단은 다수개의 요철형 돌기(5)가 구비된다. 이들 요철형 돌기(5) 들은 용기(1)의 양 측면에 형성된 다수개의 이동안내구멍(2)에 끼워지는 것이며 돌기(5)들이 해당 이동안내구멍(2)에 끼워진 상태로 각 스프링판체(3)가 스프링용기(1) 내부에 적층된다.The spring plate body 3 is composed of spring steel having high elastic force and bending deformation force, and both ends of the spring plate body 3 are provided with a plurality of uneven protrusions 5. These uneven protrusions 5 are fitted into a plurality of movement guide holes 2 formed on both sides of the container 1, and each spring plate body 3 with protrusions 5 fitted into the movement guide holes 2. ) Is stacked inside the spring container (1).

각 스프링판체(3)는 이웃한 다른 스프링판체(3)와 맞닿는 볼록부(4)가 다수개 구비된다. 볼록부(4)는 하중을 받으면 휨 변형되면서 벌어지도록 하중을 받는 부분이며 각 스프링판체(3)에 형성된 볼록부(4)는 서로 엇갈리도록 지그재그 형태로 배열된다.Each spring plate body 3 is provided with a plurality of convex portions 4 which abut another neighboring spring plate body 3. The convex part 4 is a part which receives a load so that it may be bent and deformed under load, and the convex parts 4 formed in each spring plate body 3 are arranged in a zigzag form to stagger each other.

그리고 스프링용기(1)에 적층된 스프링판체(3)중에서 제일 상단의 스프링판체(3)에 상판(6)이 놓인다. 상판(6)은 하중이 스프링판체(3)로 가해질 때 어느 한쪽으로 집중되지 않고 균일하게 퍼지도록 안내하는 하중 받침판의 역할을 한다.The top plate 6 is placed on the top plate spring 3 of the spring plate bodies 3 stacked on the spring container 1. The upper plate 6 serves as a load bearing plate that guides the spreading uniformly without being concentrated on either side when the load is applied to the spring plate body 3.

이처럼 구성된 본 발명은 스프링강으로 구성된 스프링판체(3)가 스프링용기(1) 내부에 끼워져 적층된 상태로 보관된다. 각 스프링판체(3)의 양단에는 스프링용기(1)의 양 측면에 형성된 다수개의 이동안내구멍(2)에 끼워지는 요철형 돌기(5)들이 형성되어 있음으로 이들 돌기(5)들이 해당 이동안내구멍(2)에 끼워져 스프링판체(3)가 스프링용기(1)에 내장된다.The present invention configured as described above is stored in a state in which the spring plate body (3) made of spring steel is fitted inside the spring container (1) and stacked. On both ends of each spring plate body (3) is formed a concave-convex protrusions (5) to be fitted into a plurality of movement guide holes (2) formed on both sides of the spring container (1) so that these projections (5) guide the movement The spring plate body 3 is embedded in the spring container 1 by being inserted into the hole 2.

스프링용기(1)의 최상단에 놓인 스프링판체(3)를 상판(6)으로 덮은 뒤 상판(6)에 집중하중을 가하면 각 스프링판체(3)에 형성된 볼록부(4)가 휨변형되면서 탄성력에 의해 집중하중이 받쳐진다. 그리고 각 볼록부(4)가 휨변형되는 과정에서 각 스프링판체(3)의 간격이 줄어들고 활처럼 아래로 휘게 된다. 이때 각 스프링판체(3)는 양단에 형성된 돌기(5)들이 용기(1)의 이동안내구멍(2)을 따라 미끄러지기 때문에 해당 스프링판체(3)가 무리 없이 휨변형되어 스프링판체(3)의 파손이 방지된다.Covering the spring plate body 3 placed on the top of the spring container 1 with the top plate 6 and applying a concentrated load to the top plate 6, the convex portions 4 formed on each spring plate body 3 are warped and deformed to the elastic force. Concentrated load is supported. And the spacing of each spring plate body 3 is reduced in the process of bending deformation of each convex portion 4 is bent downward like a bow. At this time, since each of the spring plate body 3, the projections (5) formed at both ends slide along the movement guide hole (2) of the container (1), the spring plate body (3) is flexibly deformed without difficulty and the spring plate body (3) Breakage is prevented.

이상에서와 같이 본 발명에 따르면 충격하중이 발생되는 절단기 또는 좁은 공간에서 집중하중이 지속적으로 발생되는 기계장치의 집중하중을 받쳐주기 위해 스프링용기와 용기에 내장되는 다수개의 스프링판체가 구비된다.As described above, according to the present invention, a plurality of spring plates are provided in the spring container and the container in order to support the concentrated load of the cutter which generates the impact load or the mechanical device that continuously generates the concentrated load in a narrow space.

각 스프링판체는 서로 떨어져 있으며 이들은 다수개의 볼록부에 의해 맞닿아 있도록 구성됨으로 집중하중이 판체에 가해지면 각 스프링판체의 볼록부가 휨변형되면서 하중이 받쳐지고 또한 각 스프링판체의 간격이 좁혀지면서 완충됨으로 좁은 공간에서 큰 하중을 받쳐줄 수 있는 등의 효과가 있다.Each spring plate is separated from each other and they are configured to be in contact with each other by a plurality of convex parts. There is an effect that can support a large load in a narrow space.
