Description
본 발명은 자동차의 유니버설조인트의 충격에너지 흡수장치에 관한 것으로, 좀 더 상세하게는 니이들(needle)핀 또는 스틸보올과의 마찰력으로 인한 하중을 흡수하여 충격으로부터 운전자를 보호할 수 있도록 하는 자동차의 유니버설조인트의 충격에너지 흡수장치에 관한 것이다.The present invention relates to an impact energy absorbing device of a universal joint of a vehicle, and more particularly, to absorb a load due to frictional force with a needle pin or a steel bowl to protect a driver from impact. The present invention relates to a shock energy absorber of a universal joint.
종래의 충격에너지 흡수장치인 칼럼(10)은 도 1에 도시되어 있다. 도 1에 도시된 바와 같이, 샤프트조인트(20)와 튜브(30)사이의 충격에너지를 흡수할 수 있도록 수지(40)로 몰딩고정하고, 튜브(30)에 삽입되지 않은 샤프트조인트(20)의 일정거리 지점에는 강구(50)를 압입하여 조립구성하였다.The column 10, which is a conventional impact energy absorber, is shown in FIG. As shown in FIG. 1, the molding is fixed with resin 40 to absorb shock energy between the shaft joint 20 and the tube 30, and the shaft joint 20 is not inserted into the tube 30. At a certain point, the steel ball 50 was press-fitted and assembled.
상기와 같이 조립구성된 칼럼(10)은 자동차의 주행중 충격에너지가 전달되면 1차적으로 샤프트조인트(20)와 튜브(30)를 몰딩고정시킨 수지(40)가 파단되면서 1차 충격에너지가 흡수된 후 샤프트조인트(20)에 압입된 강구(50)가 튜브(30)와 접촉되면서 튜브(30)를 확관시키면서 진행하여 2차적 충격에너지를 흡수하도록 되어 있다.The column 10 is assembled as described above is the first shock energy is absorbed while the resin 40, which is fixed to the molded shaft joint 20 and the tube 30 is broken when the impact energy is transmitted while driving the vehicle The steel ball 50 press-fitted to the shaft joint 20 is in contact with the tube 30 while expanding the tube 30 to absorb secondary impact energy.
그러나 상기와 같은 칼럼의 몰딩형식은 샤프트 조인트에 정밀한 삽입홈(serration)을 가공한 후 강구를 결합하여 4개의 홈에 수지로 몰딩함으로써 작업이 번거러울뿐만 아니라 가공상의 어려움이 발생되고, 또한 몰딩부의 커랩스(collapse)하중제어에 어려움이 있다.However, in the molding type of the column as described above, after machining a precise insertion groove in the shaft joint, the steel balls are combined and molded into four grooves with resin, which not only makes the work cumbersome, but also causes difficulty in processing. There is a difficulty in controlling the collapse load.
본 발명은 상기와 같은 종래의 문제점을 해결하고자 이루어진 것으로서, 그 목적은 관조인트 형상에 샤프트조인트를 압입하여 니이들핀 또는 스틸보올과의 마찰력으로 인한 하중을 흡수하도록하므로써 충격으로부터 운전자를 보호해줌과 동시에 가공 조립이 용이하여 작업능률을 향상시키고 제품의 품질을 향상시킬 수 있도록 하는데 있다.The present invention has been made to solve the conventional problems as described above, and its purpose is to protect the driver from impact by injecting the shaft joint into the pipe joint shape to absorb the load caused by the frictional force with the needle pin or steel bowl. At the same time, it is easy to assemble and process to improve work efficiency and improve product quality.
도 1은 종래의 기술을 설명하려는 칼럼의 단면도.1 is a cross-sectional view of a column to explain the prior art.
도 2는 종래의 칼럼이 작동하여 충격에너지를 흡수하는 상태도.Figure 2 is a state in which the conventional column is operating to absorb the impact energy.
도 3은 본 발명의 조립단면도.3 is an assembled cross-sectional view of the present invention.
도 4는 본 발명의 칼럼이 작동하여 충격에너지를 흡수하는 상태의 단면도.4 is a cross-sectional view of a state in which the column of the present invention operates to absorb impact energy.
