본 고안은 스트럿 쇽업저버(Strut Shock Absorber)용 내구성테스터의 편하중 작용장치에 관한 것으로서, 좀 더 구체적으로는 테스터의 전장축소로 폭이 좁은 경우에도 적용시킬 수 있도록 한 것이다.The present invention relates to a load-bearing device of a durable tester for a strut shock absorber, and more specifically, to be applied even when the width of the tester is narrow.
일반적으로 쇽업저버는 하중은 적용되지 않고 감쇄기능만을 수행하는 통형 쇽업저버와, 쇽업저버의 축외부로 차체를 지지하는 스프링이 장착되어 감쇄기능외에 하중이 작용될 때 스프링가이드 역할을 하는 표준 쇽업저버, 그리고 차체와 바퀴 사이에 경사지게 장착되므로 편하중이 작용되는 스트럿 쇽업저버로 대별된다.In general, the shock absorber is equipped with a cylindrical shock absorber which does not apply a load but performs only a damping function, and a spring that supports the vehicle body outside the shaft of the shock absorber, and serves as a spring guide when the load is applied in addition to the damping function. In addition, it is roughly mounted between the body and the wheel so that it is roughly classified as a strut shock absorber with a load.
이에 따라 스트럿 쇽업저버의 내구성테스트시에는 제1도와 같이 쇽업저버(1) 사이에 인장코일 스프링(2)을 걸어 쇽업저버에 편하중이 작용된 상태에서 내구성테스트를 실시하여야 한다.Accordingly, in the durability test of the strut shock absorber, as shown in Fig. 1, the tension coil spring 2 is interposed between the shock absorbers 1 to perform the durability test under the condition that the load is applied to the shock absorber.
이를 위해 종래에는 제2도와 같이 일측의 체결구(3a)를 일체형성하여 삽입공(4a)을 가진 보울트(4)를 나사결합하고 다른 일측의 체결구(3b)는 분할 형성하여 보울트(5)를 고정하며 상기 보울트(5)에는 삽입공(6a)을 가진 또 다른 보울트(6)를 아답터(7)로 연결하여 각 삽입공(4a)(6a)으로 인장코일스프링(2)을 걸도록 되어 있다.To this end, conventionally, as shown in FIG. 2, the fastener 3a on one side is integrally formed to screw the bolt 4 having the insertion hole 4a, and the fastener 3b on the other side is divided to form the bolt 5. The bolt 5 is connected to another bolt 6 having an insertion hole 6a by an adapter 7 so as to hook the tension coil spring 2 to each insertion hole 4a and 6a. have.
따라서 제1도에 도시한 바와 같이 테스터의 상, 하부지그(8a)(8b) 사이에 쇽업저버(1)를 장착시키고 상기 쇽업저버(1)에는 체결구(3a)(3b)를 결합한 상태에서 내구성테스트를 위해 유압실린더(9)를 가동시키면 유압실린더(9)의 동작에 따라 쇽업저버(1)가 반복적으로 승, 하강 운동을 하게되므로 내구성테스트가 가능해지게 되는데 이때 각 쇽업저버(1)에는 압축오일스프링(2)에 의해 편하중이 작용된다.Accordingly, as shown in FIG. 1, the shock absorber 1 is mounted between the upper and lower jigs 8a and 8b of the tester, and the fasteners 3a and 3b are coupled to the shock absorber 1, respectively. When the hydraulic cylinder (9) is operated for durability test, the shock absorber (1) repeatedly moves up and down according to the operation of the hydraulic cylinder (9), so that the durability test is possible. In this case, each shock absorber (1) Unloading load is acted on by the compressed oil spring 2.
그러나 이러한 종래의 장치는 테스터에 쇽업저버를 장착할때 쇽업저버(1)의 간격이 좁을 경우에는 아답터의 변위량이 적기 때문에 인장코일스프링(2)의 탄성계수가 큰 것을 사용하여야 되었음은 물론 작용하중이 클 경우에는 설치위치가 한정되어 부하를 걸기가 곤란하게 되는 문제점이 있었다.However, in the conventional apparatus, when the shock absorber 1 is mounted on the tester, when the gap between the shock absorber 1 is narrow, the displacement of the adapter is small, so that the elastic modulus of the tension coil spring 2 has to be used. In this large case, there is a problem in that the installation position is limited and it is difficult to apply a load.
본 고안은 종래의 이와 같은 문제점을 해결하기 위해 안출한 것으로서 그 구조를 개선하여 작용하중이 클 경우에도 인장코일 스프링계수의 변위조정이 용이해질 수 있도록 하는데 그 목적을 갖는다.The present invention has been made to solve such a problem in the prior art has an object to improve the structure to facilitate the displacement adjustment of the tension coil spring coefficient even when the working load is large.
상기 목적을 달성하기 위한 본 고안의 형태에 따르면, 분할형성되어 양측 쇽업저버에 체결되고 수평방향의 나사구멍이 형성된 체결구와, 상기 양측 체결구에 형성된 각 나사구멍에 나사끼우기로 결합된 간격조절용 보울트와, 상기 양측 간격조절용 보울트의 삽입공 사이에 결합되어 테스트하는 쇽업저버에 편하중을 작용시키는 인장코일스프링을 포함하여 구성된 스트럿 쇽업저버용 내구성테스터의 편하중 작용장치가 제공된다.According to an aspect of the present invention for achieving the above object, a fastener formed by splitting and fastening to both shock absorbers and having a horizontal threaded hole, and a bolt for adjusting a spacing coupled to each threaded hole formed in the fastening both sides. And, there is provided a single load acting device of the durability tester for strut shock absorber comprising a tension coil spring coupled between the insertion hole of the gap adjusting bolts on both sides to exert a load on the shock absorber to be tested.
이하, 본 고안을 일실시예로 도시한 첨부된 도면 제3도를 참고로하여 더욱 상세히 설명하면 다음과 같다.Hereinafter, with reference to Figure 3 of the accompanying drawings showing an embodiment of the present invention in more detail as follows.
첨부도면 제3도는 본 고안 장치의 요부를 나타낸 평면도로서, 본 고안은 분할형성된 체결구(10)에 양측으로 나사구멍(103)이 형성되어 있고 상기 각 나사구멍에는 삽입공(113)이 형성된 간격조절용 보울트(11)가 나사끼우기로 결합되어 있으며 상기 삽입공에는 테스트하고자 하는 쇽업저버(1)에 편하중을 작용시키는 인장코일스프링(2)이 걸려 있다.3 is a plan view showing the main part of the present device, the present invention is a screw hole 103 is formed on both sides of the fastener 10 is formed separately, the spacing hole 113 is formed in each of the screw holes The adjusting bolt 11 is coupled by threading, and the insertion hole has a tension coil spring 2 for exerting a load on the shock absorber 1 to be tested.
상기 분할된 체결구(10)는 도시하지 않은 보울트에 의해 쇽업저버(1)의 상부에 체결된다.The divided fastener 10 is fastened to the upper portion of the shock absorber 1 by a bolt (not shown).
이와 같이 구성된 본 고안의 작용 효과를 설명하면 다음과 같다.Referring to the effects of the present invention configured as described above are as follows.
쇽업저버(1)의 내구성테스트시 편하중이 걸리도록 하기 위해 분할 형성된 체결구(10)를 쇽업저버(1)의 상부에 서로 맞댄 다음 이들을 보울트로 체결한 후 각 체결구(10)에 형성된 나사구멍(103)에 간격조절용 보울트(11)를 결합한다.In order to take the load on the shock absorber 1, the fasteners 10, which are divided into parts, are placed against the upper part of the shock absorber 1, and then fastened with a bolt. Couple the gap adjusting bolt 11 to the hole 103.
그 후 각 간격조절용 보울트(11)에 형성된 삽입공(11a)으로 인장코일스프링(2)의 양단을 걸고 테스트시 쇽업저버(1)에 작용시키고자 하는 하중에 따라 간격조절용 보울트(11)를 시계 또는 반시계 방향으로 회전시키면 인장코일스프링(2)에 작용되는 하중만큼 쇽업저버(1)가 유압실린더(9)에 의해 계속적인 승, 하강운동을 할때 쇽업저버에 편하중이 작용되므로 쇽업저버(1)가 차체에 비스듬히 장착된 상태에서의 내구성테스트가 가능하게 된다.Thereafter, both ends of the tension coil springs 2 are inserted into the insertion holes 11a formed in each gap adjusting bolt 11, and the gap adjusting bolt 11 is watched according to the load to be applied to the shock absorber 1 during the test. Alternatively, if the counterclockwise rotation rotates counterclockwise, the shock absorber (1) acts as a load on the shock absorber when the shock absorber (1) continuously moves up and down by the hydraulic cylinder (9). The durability test can be performed when (1) is mounted obliquely on the vehicle body.
이상에서와 같이 본 고안 장치는 각 체결구(10)에 간격조절용 보울트(11)가 나사끼우기로 결합되어 있어 양측으로 변위가 가능하여 인장코일스프링(2)이 작용되는 하중을 폭넓게 가변시키게 되므로 테스터의 전장이 축소되고 쇽업저버 사이의 폭이 좁은 테스터의 경우에도 적용가능하게 됨은 물론 변동의 아답터를 가공할 필요가 없게되므로 가공이 용이해지게 되는 효과를 얻게된다.As described above, the device of the present invention is coupled to each fastener 10 by the bolts for adjusting the spacing, so that both sides can be displaced so that the load of the tension coil spring 2 can be varied widely. This reduces the overall length of the tester and makes it possible to apply the tester with a narrow width between shock absorbers as well as to facilitate the process because it is not necessary to process the variable adapter.
또한, 체결구(10)에 나사구멍(103)이 형성되어 있어 방향에 구애받지 않고 체결구를 쇽업저버에 결합시키게 되는 효과도 얻게된다.In addition, the screw hole 103 is formed in the fastener 10, so that the fastener can be coupled to the shock absorber regardless of the direction.
