본 고안은 조향축의 충격흡수장치에 관한 것으로, 특히 W자형의 충격흡수판을 이용하여 자동차의 충돌 사고시 크고 작은 충격하중을 효과적으로 흡수할 수 있도록 된 조향축의 충격흡수장치에 관한 것이다.The present invention relates to a shock absorbing device of the steering shaft, and more particularly to a shock absorbing device of the steering shaft to be able to effectively absorb the large and small impact load in the event of a car crash using the W-shaped shock absorbing plate.
일반적으로 자동차의 조향축은 충격을 흡수할 수 있는 구조되어 있는 바, 이는 자동차 충돌사고시 운전자의 가슴부위를 강타하는 하중을 적게하여 충돌에 의한 운전자를 보호하기 위함이다. 즉, 이같은 조향축 충격흡수장치는 앞서 말한 바와같이 자동차의 충돌사고때의 운전자의 부상을 가볍게 하기 위한 기구이며, 충돌에 의해 차체가 파손되었을때 핸들부의 조향장치가 운전자쪽으로 튀어나와서 운전자가 부상을 당하는 것과 동시에 운전자가 관성에 의해 조향장치에 부딪힐때의 충격을 완화시키는 장치이다.In general, the steering shaft of the vehicle is structured to absorb shocks, which is to protect the driver from a collision by reducing the load that hits the driver's chest during an automobile crash. In other words, as described above, the steering shaft shock absorber is a mechanism for lightening the driver's injury in the event of a crash of the vehicle. At the same time, it is a device to alleviate the impact when the driver hits the steering system by inertia.
상기와 같은 종래의 조향축 충격흡수장치는 제2도에 도시된 바와같이 상부샤프트(12)와 하부샤프트(11)사이의 중간부위에 테이퍼진 연결용튜브(13)가 설치되되, 상기 연결용튜브(13)의 하부에 내접된 하부샤프트(11)에는 여러개의 폴리아세탈핀(17)이 장착되어 있으며, 상기 연결용튜브(13)에 내접된 하부샤프트(11)의 외부쪽으로 강철보올(18)이 끼워진 구조로 되어 있음에 따라, 자동차가 충돌되었을때 충돌에너지는 하부샤프트(11)로 전달되는데, 이때 전달되는 충격에너지는 1차적으로 상기 폴리아세탈핀(17)을 파괴시키면서, 상기 하부샤프트(11)를 전진 이용시키고, 2차적으로는 상기 강철보올(18)이 연결용튜브(13)내면을 긁어 지나가면서 소성변형을 일으켜, 충격을 흡수하도록 되어 있다.In the conventional steering shaft shock absorbing device as described above, a tapered connection tube 13 is installed at an intermediate portion between the upper shaft 12 and the lower shaft 11, as shown in FIG. The lower shaft 11 inscribed in the lower portion of the tube 13 is equipped with a plurality of polyacetal pins 17, and the steel bowl 18 toward the outside of the lower shaft 11 inscribed in the connecting tube 13. As the structure is fitted, the collision energy is transmitted to the lower shaft 11 when the vehicle collides, and the impact energy transmitted is primarily destroyed the polyacetal pin 17, and the lower shaft (11) is used forward, and secondly, the steel bowl (18) scrapes through the inner surface of the connecting tube (13), causing plastic deformation and absorbing the impact.
여기서, 충격흡수시 하부샤프트(11)의 밀림 스트로크는 1이다.Here, the push stroke of the lower shaft 11 at the time of shock absorption is one.
이같은 구조로 되어 있는 종래의 조향축 충격흡수장치는 다양한 부품등으로 인해 조립가공이 복잡하고 생산비가 높은 것이 문제점으로 제기되어 왔다.The conventional steering shaft shock absorbing device having such a structure has been raised as a problem of complicated assembly processing and high production cost due to various components.
이에 본 고안 상기와 같은 문제점을 해결하기 위해 안출해낸 것으로, W자형의 충격흡수판을 하부샤프트와 연결용튜브에 설치하므로써 구조를 간단히 하여, 생산성 향상을 도모한 자동차의 조향축 충격흡수장치를 제공함에 그 목적이 있다.The present invention has been made to solve the above problems, by providing a W-shaped shock absorbing plate to the lower shaft and the connecting tube to simplify the structure, to provide a steering shaft shock absorbing device of the vehicle to improve the productivity. Has its purpose.
상기와 같은 목적을 달성하기 위한 본 고안에 따른 조향축 충격흡수장치는 하부샤프트와 상부샤프트 사이에 연결용 튜브를 끼워 설치하되, 상기 하부샤프트와 연결용 튜브가 접하는 부위에는 W자형의 충격흡수판을 설치하여 이루어진 구조로 되어 있다.Steering shaft shock absorbing device according to the present invention for achieving the above object is installed by inserting a connecting tube between the lower shaft and the upper shaft, the W-shaped shock absorbing plate in the contact area with the lower shaft and the connecting tube. It is structured by installing.
이하 본 고안을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
본 고안은 하부샤프트(1)와 상부샤프트(2) 사이에 연결용튜브(3)가 끼워 연결되고, 상기 하부샤프트(1)의 자유단인 한쪽선단(1a)과 이 한쪽선단(1a)에 외접하여 끼워진 연결용튜브(3) 사이에는 W자형의 충격흡수판(4)이 끼워 설치되되, 이 W자형 충격흡수판(4)은 상기 하부샤프트(1)의 한쪽선단(1a)과 연결용튜브(3)와의 고정핀(5a,5b)들을 매개로 고정설치 되어져 있다.According to the present invention, a connecting tube 3 is inserted between the lower shaft 1 and the upper shaft 2 and connected to one end 1a, which is a free end of the lower shaft 1, and the one end 1a. A W-shaped shock absorbing plate 4 is inserted between the externally fitted connecting tubes 3, and the W-shaped shock absorbing plate 4 is connected to one end 1a of the lower shaft 1 for connection. The fixing pins 5a and 5b with the tube 3 are fixedly installed.
이와 같이 이루어진 본 고안은 도 1에 도시된 바와같이 조향축(6)이 2개로 나누어져 상.하부샤프트(1,2)로 이루어져 있으며, 이들 상.하부샤프트(1,2) 사이는 연결용튜브(3)로 연결되어 있고, 상기 하부샤프트(1)와 연결용튜브(3)의 접하는 부위에는 W자형의 충격흡수판(4)이 고정핀(5a,5b)들을 매개로 끼워져 설치되어져 있다.1, the steering shaft 6 is divided into two and consists of upper and lower shafts 1 and 2, and the upper and lower shafts 1 and 2 are connected to each other. It is connected to the tube (3), the W-shaped shock absorbing plate (4) is provided in the contact portion of the lower shaft (1) and the connecting tube (3) through the fixing pins (5a, 5b). .
따라서 자동차가 장애물등에 충돌하여 기어박스(도면에 도시되어 있지 않음) 쪽에서 조향축(6)의 하부샤프트(1)쪽으로 힘을 가하게 되면, 이 충격에너지에 의해 조향축(6)의 하부샤프트(1)가 도 1에 점선으로 도시된 바와같이, 상기 연결용튜브(3)내로 밀고 들어가게 되는바, 이때에 상기 W자형의 충격흡수판(4)의 외측부위와 연결용튜브(3)에 설치된 고정핀(5a)들이 고정되어 있으므로, 하부샤프트(1)의 선단(1a)에 고정된 W자형의 충격흡수판(4)과 이 하부샤프트(1)는 연결용튜브(3)의 안쪽면을 따라 전진하면서 충격에너지를 면접촉으로 흡수하도록 되어 있다.Therefore, when a vehicle collides with an obstacle and applies a force from the gearbox (not shown) to the lower shaft 1 of the steering shaft 6, the impact shaft lower shaft 1 of the steering shaft 6 by this impact energy. As shown by the dotted line in Fig. 1, pushed into the connecting tube (3), at this time the outer portion of the W-shaped shock absorbing plate (4) and the fixing pins installed on the connecting tube (3) Since the 5a are fixed, the W-shaped shock absorbing plate 4 fixed to the tip 1a of the lower shaft 1 and the lower shaft 1 are advanced along the inner surface of the connecting tube 3. While absorbing the impact energy by surface contact.
상기와 같이 본 고안에 따른 조향축 충격흡수장치는 상.하부샤프트(1,2) 사이에 설치된 연결용튜브(3)은 상기 하부샤프트(1) 사이에 W자형의 충격흡수판(4)이 설치된 간단한 구조로 의해 조립가공이 간편할 뿐만 아니라, 생산성 향상을 도모할 수 있는 효과를 지니고 있다.As described above, the steering shaft shock absorbing device according to the present invention has a connection tube 3 installed between the upper and lower shafts 1 and 2 to form a W-shaped shock absorbing plate 4 between the lower shafts 1. The simple structure installed makes it easy to assemble and process, and has the effect of improving productivity.
