본 발명은 자동차에서 변속기와 바퀴 사이를 연결하면서 구동력을 전달하는 엑슬축(AXLE SHAFT)에 관한 것으로, 본 출원인의 선출원인 10-2006-0004424호를 더욱 개선하여 공정의 단순화로 좀 더 간편하게 액슬축을 제조하고 스플라인이 형성되는 부분의 강도 또한 향상시킬 수 있도록 한 것이다.The present invention relates to an axle shaft for transmitting a driving force while connecting between a transmission and a wheel in an automobile, and further improves the applicant's prior application No. 10-2006-0004424 to simplify the process by simplifying the axle shaft. It is also intended to improve the strength of the part where the spline is formed.

주지된 바와 같이 자동차에서는 엔진에서 발생하는 구동력이 변속기를 통하여 변속된 후 엑슬축에 의해 바퀴에 전달되어 주행이 이루어지는 것으로, 엑슬축은 양 측단에 스플라인이 형성되어 회전동력을 전달하게 된다.As is well known, the driving force generated in the engine is transmitted to the wheels by the axle shaft after the transmission is generated through the transmission, and the axle shaft is formed with splines at both ends to transmit rotational power.

이러한 엑슬축은 종래 환봉재료를 선삭가공하여 사용되었는데, 자동차의 주행과정에서 차체 흔들림과 엔진출력 음에 의한 진동노이즈가 엑슬축에 그대로 전달되어 제동구동품질에 치명적인 결합이 발생되었고, 이에 따라서 노이즈방지용 패드(PAD)를 추가로 부착하여 사용해야 하는 단점이 있었다.This axle shaft is conventionally used by turning round rod material. In the process of driving a vehicle, vibration noise caused by vehicle shaking and engine output sound is transmitted to the axle shaft as it is, resulting in a fatal coupling to braking driving quality. (PAD) had to be used by attaching additionally.

그리고 일부 차종의 경우에는 튜브의 양단에 환봉을 용접하여 엑슬축을 구성하는 경우가 있기는 하였지만 제조공정에 시간이 많이 소요되고 까다로우면서, 용접부위에 결함이 많이 발생하는 단점이 있었다.In some models, the axle shaft may be formed by welding round rods at both ends of the tube, but the manufacturing process is time-consuming and demanding, and has a disadvantage in that a lot of defects are generated in the welding part.

상기한 문제점을 해결하기 위해 본 출원인은 튜브(파이프형 관체)를 이용하되 절삭가공이 아닌 압출공정 및 전조 등의 공정을 통하여 엑슬축으로서의 필요한 형상을 완성함으로써 종래에 비하여 차량에 장착하여 작동시 소음의 발생을 감소시키며, 재질의 낭비가 적고 용이하게 제조가 가능한 방법과 그에 의한 튜브형 엑슬축에 관한 기술을 선출원한 바 있다.In order to solve the above problems, the applicant uses a tube (pipe type tube), but completes the required shape as an axle shaft through a process such as an extrusion process and a rolling process, not a cutting process. It has been previously filed a method of reducing the occurrence of, reducing waste of materials and making it easy to manufacture, and a technique related to a tubular axle shaft.

그러나 상기 선출원에 의하면 양단의 스플라인을 형성하기 위한 부분을 구성하기 위하여 원래 소재의 직경에 비하여 큰 비율로 직경을 축소하기 위해 여러 단계의 축소 공정이 필요하므로 시간이 많이 소요되는 문제점이 있으며, 여러 번의 직경 축소로 인하여 스플라인이 형성되는 부분의 두께가 어느 정도 증가 하기는 하지만 원하는 강도를 얻기에는 두께가 부족한 것이었다.However, according to the above application, there is a problem that it takes a long time because several steps of reduction process are required to reduce the diameter to a large ratio compared to the diameter of the original material in order to form a part for forming the spline at both ends. Although the thickness of the spline is increased to some extent due to the reduction in diameter, the thickness was insufficient to obtain the desired strength.

또한 여러번 반복되는 소성가공에 의해 재질의 경도가 저하 또는 불균일화 되는 등의 문제가 있었던 것이다.In addition, there was a problem that the hardness of the material is lowered or uneven due to repeated plastic processing.

상기한 문제점을 감안하여 안출한 본 발명은 튜브형의 소재를 이용하고 양단을 압출방식으로 축관(직경을 축소시킴)하면서 원하는 형상의 엑슬축을 형성하되, 두께를 증대시키는 작업 없이 원 소재의 두께를 두꺼운 것으로 사용하면서 스플라인의 형성이 필요 없는 중앙 부분의 두께를 줄이는 방식으로 제조함으로써 선출원에 비하여 좀 더 간단하고 빠르게 제조를 완성하면서도 충분한 강도를 얻을 수 있는 엑슬축을 제공함을 목적으로 하는 것이다.The present invention devised in view of the above problems is to form axle shaft of the desired shape while using a tubular material and both ends of the shaft tube by the extrusion method (reducing the diameter), without increasing the thickness of the thickness of the raw material thick The purpose of the present invention is to provide an axle shaft that can be manufactured in a manner that reduces the thickness of the central portion that does not require the formation of a spline, and thus obtains sufficient strength while completing the manufacturing more simply and quickly than the previous application.

본 발명은 미리 스플라인이 형성되는 부분이 필요한 충분한 두께를 전체적으로 갖고 계산된 길이와 강도를 갖는 튜브형의 소재를 준비한 후, 스플라인이 형성 되는 부분은 축관을 하고 그 나머지 부분은 두께를 줄이는 방법으로 형상을 만들며, 축관된 부분에 각각 스플라인의 형성과 나머지 필요한 롤링부 등의 요홈을 형성하여 엑슬축을 완성하는 것을 특징으로 하는바, 이하 첨부된 도면에 의거 본 발명을 상세히 살펴보면 다음과 같다.According to the present invention, after preparing a tubular material having a calculated thickness and strength as a whole, a portion of which a spline is formed in advance is required, and a portion of which a spline is formed is a shaft and the remaining portion is formed by reducing the thickness. Making and forming the spline in each of the condensed portion and forming the grooves such as the remaining required rolling portion to complete the axle shaft, the present invention in detail with reference to the accompanying drawings as follows.

제 1공정: 소재준비First Step: Material Preparation

본 발명은 엑슬축으로서 원하는 강도를 갖는 재질을 선택하고, 가공 후 엑슬축 양단의 스플라인이 형성되는 부분이 필요한 두께를 전체적으로 가지며, 길이는 완성되는 엑슬축의 규격을 감안하여 필요한 길이를 갖는 관체형의 소재(1)를 준비한다.The present invention selects a material having a desired strength as the axle shaft, and after processing, the portion where the spline is formed on both ends of the axle shaft has the required thickness as a whole, the length of the tubular shape having the required length in consideration of the specifications of the completed axle shaft Prepare the material 1.

제2공정: 일측 축관Second Process: One Side Shaft

소재(1)의 일측에 스플라인이 형성되는 길이를 감안하여 단부 일부분의 외경을 압출(EXTRUDE) 공정으로 축소시켜주는 것이다.In consideration of the length of the spline is formed on one side of the material (1) is to reduce the outer diameter of the end portion by the extrusion (EXTRUDE) process.

이때 소재(1)의 외경보다 작은 내경을 가진 다이스(10)를 통과시키는 공정을 몇 단계로 분할하여 점차 직경을 축소하여 원하는 직경을 얻는다.At this time, the process of passing the die 10 having an inner diameter smaller than the outer diameter of the raw material 1 is divided into several steps to gradually reduce the diameter to obtain a desired diameter.

제3공정: 중앙부 두께 축소3rd process: thickness reduction at center

상기 외경이 축소된 부분 다음으로부터는 기존의 내경보다 조금 작은 외경의 내부다이스(10')와 외부의 다이스(11)를 동시에 통과하도록 함으로써 상기 공정에서 외경이 축소된 다음 부분으로부터는 소재(1)의 내경을 조금 축소하면서 외경을 더 크게 축소함으로써 두께를 감소시키는 것이다.From the portion after the outer diameter is reduced, the inner die 10 'and the outer die 11 having a smaller diameter than the existing inner diameter are simultaneously passed through the portion after the outer diameter is reduced. The thickness is reduced by reducing the inner diameter of the lens and making the outer diameter larger.

이러한 작업을 상기와는 반대편 끝단의 스플라인이 형성되기 시작하는 부분까지 계속한다.This operation continues to the point where the spline at the opposite end begins to form.

제4공정: 타측 축관Fourth Step: Other Shaft Pipe

상기한 공정이 완료된 다음 소재(1)의 내부에 있던 내부다이스(10)를 제거한 후 다이스(10)를 통과시키는 과정을 계속하면 되는데, 내부다이스(10')를 제거한 상태에서 소재(1)가 다이스(11)를 통과함으로 상기 제3공정에서 두께가 축소된 부분을 제외한 나머지 끝단부에는 소재(1)의 두께는 그대로 유지되는 상태에서 내경과 외경이 축소되어 제1공정에서와 같이 반대측 단부와 같은 단면형태가 이루어지는 것이다.After the above process is completed, the internal dice 10 in the interior of the material 1 may be removed and the process of passing the die 10 may be continued. The material 1 may be removed while the internal dice 10 'are removed. The inner and outer diameters are reduced in the state where the thickness of the material 1 is maintained at the remaining ends except the portion whose thickness is reduced in the third process by passing through the die 11, The same cross-sectional shape is achieved.

제5공정: 양측단 2차 축관5th Process: 2nd Side Secondary Tube

상기 상태의 소재 양단을 직경이 좀 더 작은 다이스(12)를 통과시킴으로써 양단부분의 두께는 중앙의 다른 부분보다 두꺼운 상태에서 외경이 중앙의 다른 부분보다 축소된 형태를 만들어 준다.By passing both ends of the material in the above state with a smaller diameter die 12, the thickness of both ends is made thicker than the other part in the center, making the outer diameter smaller than the other parts in the center.

제6공정: 스플라인 형성Step 6: Spline Formation

유압식 스플라인 다이스를 이용하여 압출 방식으로 스플라인을 형성하는데, 소재의 양측 직경이 축소된 부분을 스플라인 홈이 형성된 다이스를 통과하도록 함으로써 스플라인(2)(2')이 형성되도록 한다.The spline is formed by extrusion using a hydraulic spline die. The spline 2, 2 'is formed by passing a portion having a reduced diameter on both sides of the material through a die having a spline groove.

제7공정: 롤링부 전조7th Step: Rolling Part Rolling

양단의 스플라인이 형성되지 않은 직경이 큰 부분 등 몇 개소에 일반적인 엑슬축으로서 필요한 형태의 요철형상을 롤링 전조방식으로 가공한 롤링부(3)(3')를 형성한다.Rolling portions 3 and 3 'are formed by rolling rolling the uneven shape required as a general axle shaft in a number of places such as a large diameter portion where both ends of the spline are not formed.

제8공정: 스냅링 홈 가공8th Step: Snap Ring Grooving

스플라인(2)(2')이 형성된 중간에 스냅링을 삽입할 수 있는 링홈(4)을 선삭가공한다.The ring groove 4 which can insert a snap ring in the middle in which the spline 2, 2 'was formed is turned.

제9공정: 마무리Step 9: finish

가공이 완성된 제품의 표면을 세척하고 방청처리한 후, 검사를 통하여 불량을 선별함으로써 제조공정이 완성된다.After the surface of the finished product is washed and rust treated, the inspection process is completed to complete the manufacturing process.

상기와 같은 방법으로 완성된 엑슬축(20)은 양단의 일부 길이 구간은 직경이 중앙부보다 작으면서 원래 소재의 두께를 그대로 유지하는 두꺼운 관체형이면서 외면에 스플라인(2)(2')이 형성되어 있으며, 중앙부는 압출에 의해 내경보다 외경이 더 축소되어 두께가 축소된 상태의 관체형이고, 전조에 의한 수개의 롤링부(3)(3')가 형성된 형태이다.The axle shaft 20 completed as described above has a spline (2) (2 ') formed on the outer surface while being a thick tubular shape in which some length sections of both ends are smaller than the central portion and maintain the thickness of the original material. The center portion is tubular in a state in which the outer diameter is further reduced by the extrusion to reduce the thickness, and the rolling portion 3 (3 ') formed by rolling is formed.

이러한 본 발명에 의하면 전체적으로 튜브를 이용하여 엑슬축을 형성하므로 내부가 중공이 되는 것으로서, 종래의 엑슬축에 비하여 무게를 절감할 수 있으면서도 용접에 의한 연결부가 없으면서 압출에 의한 소성가공으로 재질의 밀도가 향상되어 비틀림 응력이나 회전토르크에 견디는 힘이 강하고 높은 인장강도 등을 얻을 수 있는 것이다.According to the present invention, the axle shaft is formed by using the tube as a whole, so that the inside is hollow, and the weight can be reduced compared to the conventional axle shaft, but the density of the material is improved by plastic processing by extrusion without connecting parts by welding. As a result, the force to withstand torsional stress and rotational torque is strong and high tensile strength can be obtained.

또한 중공인 튜브형이므로 일측에서 발생한 노이즈의 전달 정도가 미미하여 별도의 노이즈 억제를 위한 구성이 필요 없을 정도로 승차감이나 제동, 구동품질이 향상된다.In addition, since the hollow tube type, the transmission degree of noise generated from one side is insignificant, so that the riding comfort, braking, and driving quality are improved so that a separate configuration for noise suppression is not necessary.

특히 상기 선출원과 비교할 때도 앞에서 설명한 바와 같이 미리 소재를 준비시에 양단의 스플라인 형성 부분이 요구하는 두께를 가진 것으로 선택함으로써 직경이 줄이면서 두께를 늘여야 하는 공정이 단순해지므로 생산이 용이하게 되는 것이고, 직경을 줄이면서 두께를 늘인 선출원에 비하여 스플라인이 형성된 부분의 강도 또한 향상되는 것이다.In particular, compared with the above-mentioned application, as described above, by selecting the material having the thickness required by the spline forming portions at both ends in preparation, the process of reducing the diameter and increasing the thickness is simplified, so that the production is easy. The strength of the splined portion is also improved compared to the previous application of increasing thickness while reducing the diameter.

이상 설명한 바와 같은 본 발명에 의하면 비교적 간단한 압출방식에 의해 튜브 타입의 엑슬축을 제조할 수 있게 된 것으로서, 제조원가를 인하시킬 수 있으면서 무게를 절감하고 내구성이 더욱 향상되는 효과가 있고 노이즈의 발생을 방지할 수 있는 등 매우 진보된 엑슬축을 제공할 수 있으며, 상기 본 출원인의 선출원에 비하여 공정을 더욱 단순히 하고 강도 또한 향상시키게 되는 등 더욱 진보된 발명이라 할 수 있다.According to the present invention as described above it is possible to manufacture a tube-type axle shaft by a relatively simple extrusion method, it is possible to reduce the manufacturing cost while reducing the weight and further improve the durability and prevent the occurrence of noise It is possible to provide a very advanced axle shaft, and the like, and more advanced invention, such as to simplify the process and improve the strength compared to the applicant of the applicant.
