It can be divided into appliances.
도 1에는 일반적인 독립 현가식 조향장치의 구성을 개략적으로 도시하였다. 운전자가 조향휘일(2)을 회전시키면 조향휘일(2)의 조작력은 조향칼럼(3)내에 장착된 조향축(4)을 통해 기어박스(5)로 전달되며, 기어박스(5)는 조향축(4)의 회전을 감속하여 조작력을 증대시킴과 동시에, 조작기구의 운동방향을 바꾸어 피트먼 아암(6) 및 드래그 링크(7)를 거쳐 중심링크(8)로 전달한다.1 schematically illustrates a configuration of a general independent suspension steering apparatus. When the driver rotates the steering wheel 2, the operating force of the steering wheel 2 is transmitted to the gearbox 5 through the steering shaft 4 mounted in the steering column 3, and the gearbox 5 is the steering shaft 5. The rotation of (4) is decelerated to increase the operating force, and at the same time, the direction of movement of the operating mechanism is changed and transmitted to the center link 8 via the pitman arm 6 and the drag link 7.

상술한 본 고안의 목적은 조향축을 통해 전달된 조향휘일의 회전수를 감속하는 기어박스와, 기어박스를 통해 증대된 조작력을 피트먼 아암 및 드래그 링크를 거쳐 타이로드로 전달하는 중심링크와, 타이로드로 전달된 조작력에 의해 킹핀을 중심으로 조향륜을 회전시키는 너클 스핀들로 구성된 자동차용 조향장치에 있어서, 중심링크에는 다수의 댐핑 돌기를 지닌 직경 축소부가 형성되어 있으며, 직경 축소부에는 댐핑 돌기를 통해 전달되는 진동을 흡수하는 댐핑 고무가 장착된 것을 특징으로 하는 자동차용 조향장치의 중심링크 댐핑구조에 의해서 달성된다.An object of the present invention described above is a gearbox for reducing the rotational speed of a steering wheel transmitted through a steering shaft, a center link for transmitting the increased operating force through a gearbox to a tie rod through a pitman arm and a drag link, and a tie. In the steering device for automobiles consisting of a knuckle spindle that rotates the steering wheel around the kingpin by the operating force transmitted to the rod, the center link is formed with a diameter reducing portion having a plurality of damping protrusions, the diameter reducing portion a damping protrusion It is achieved by the center link damping structure of the steering device for a vehicle, characterized in that the damping rubber is mounted to absorb the vibration transmitted through.
이하, 첨부한 도 2와 도 3을 참조하여 본 고안의 바람직한 실시예에 따른 자동차용 조향장치의 중심링크 댐핑구조에 대하여 상세히 설명한다.Hereinafter, with reference to the accompanying Figures 2 and 3 will be described in detail the center link damping structure of the steering apparatus for a vehicle according to a preferred embodiment of the present invention.
도 2는 본 고안의 자동차용 조향장치의 중심링크 댐핑구조를 보인 개략도이며, 도 3은 도 2의 A부분 확대 단면도로, 도 1에서 설명한 종래의 구조와 동일 부품은 동일 부호로 표시한다.Figure 2 is a schematic view showing the center link damping structure of the steering device for a vehicle of the present invention, Figure 3 is an enlarged cross-sectional view of the portion A of Figure 2, the same parts as the conventional structure described in Figure 1 are denoted by the same reference numerals.
먼저, 도 1에서 설명한 바와 같이, 운전자가 조향휘일(2)을 회전시키면, 기어박스(5)는 조향축(4)을 통해 전달되는 조향휘일(2)의 회전수를 감속하여 토오크를 증대시킨 다음에, 증대된 조작력을 피트먼 아암(6) 및 드래그 링크(7)로 전달하게 되며, 드래그 링크(7)로 전달된 힘은 중심링크(18)와 타이로드(9), (9')를 통해 너클 스핀들(10), (10')로 전달되며, 너클 스핀들(10), (10')은 킹핀을 중심으로 조향륜(12), (12')을 회전시켜 차량의 진행방향을 변경할 수 있게 된다.First, as described in FIG. 1, when the driver rotates the steering wheel 2, the gear box 5 reduces the rotation speed of the steering wheel 2 transmitted through the steering shaft 4 to increase torque. Then, the increased operating force is transmitted to the pitman arm 6 and the drag link 7, and the force transmitted to the drag link 7 is the center link 18, the tie rods 9, and 9 ′. It is transmitted to the knuckle spindles 10 and 10 ', and the knuckle spindles 10 and 10' change the direction of travel of the vehicle by rotating the steering wheels 12 and 12 'around the kingpin. It becomes possible.
또한, 본 고안에서는 노면으로부터 전달되는 충격이나 조향장치 자체의 진동을 감쇠하기 위한 방안으로, 중심링크(18)의 중앙 부분의 형상을 변경한 다음, 이 부분에 진동을 감쇠하는 댐핑 고무(30)를 장착하여 조정 안정성을 향상시켰다. 이를 다음의 도 3에서 설명한다.In addition, in the present invention, in order to dampen the shock transmitted from the road surface or the vibration of the steering apparatus itself, the damping rubber 30 for changing the shape of the central portion of the center link 18, and then damping the vibration in this portion. Improved stability of adjustment by mounting. This will be described in the following FIG. 3.
도 3은 도 2의 A부분을 확대하여 도시한 단면도로, 여기에는 본 고안에 따른 중심링크의 댐핑구조가 단면된 상태로 도시되어 있다.3 is an enlarged cross-sectional view of a portion A of FIG. 2, in which the damping structure of the center link according to the present invention is shown in a cross-sectional state.
도시한 바와 같이, 드래그 링크(7)를 통해 전달된 조작력을 타이로드를 통해 너클 스핀들(10), (10')로 전달하는 중심링크(18)의 일부분의 직경을 작게 형성한 다음, 이 직경 축소부(18a)에는 외주부로부터 수직으로 연장되는 다수의 댐핑 돌기(20, 20', 20)를 형성하였다. 또한, 댐핑 돌기(20, 20', 20)의 외측에는 압축강도가 높은 댐핑 고무(30)를 끼워 감쇠력을 증대시켰다.As shown, the diameter of the portion of the center link 18 which transmits the operating force transmitted through the drag link 7 to the knuckle spindles 10 and 10 'via the tie rod is made small, and then the diameter In the reduction portion 18a, a plurality of damping protrusions 20, 20 ', 20 extending vertically from the outer circumference portion are formed. In addition, the damping force is increased by inserting a damping rubber 30 having a high compressive strength to the outside of the damping protrusions 20, 20 ′, 20.
중심링크(18)의 직경 축소부(18a)에 형성된 댐핑 돌기(20, 20', 20)를 보면, 중앙의 돌기(20)를 중심으로 중심링크(18)의 길이방향을 따라 양단으로 갈수록 길이를 길게 형성하였다. 즉, 중앙의 돌기(20)에 비해 다음의 돌기(20')를 보다 길게 형성하였으며, 이 돌기(20')의 외측에 배치된 돌기(20)의 길이를 보다 길게 형성함으로써, 진동의 크기에 따라 효과적으로 흡수할 수 있도록 하였다.Looking at the damping protrusions 20, 20 ', 20 formed in the diameter reducing portion 18a of the center link 18, the length toward the both ends along the longitudinal direction of the center link 18 with respect to the center projection 20 in the center Was formed long. That is, the next protrusion 20 'is formed longer than the center protrusion 20, and the length of the protrusion 20 disposed outside the protrusion 20' is made longer, so that the size of the vibration is increased. Therefore, it can be effectively absorbed.
즉, 미세한 진동 및 중간 정도의 진동이 전달되는 경우에는 길이가 작은 중앙 돌기(20) 및 인접하게 배치된 다음 돌기(20')를 통해 흡수하게 되며, 강한 진동이 전달되는 경우에는 가장 외측에 배치된 돌기(20)를 통해 진동을 흡수하게 된다.That is, when fine and medium vibrations are transmitted, they are absorbed through the small central protrusion 20 and the adjacent protrusions 20 ', which are disposed at the outermost side when strong vibrations are transmitted. The vibration is absorbed through the protrusion 20.
이상으로 설명한 본 고안에 의하면, 중심링크의 일부분의 직경을 축소시켜 다수의 댐핑 돌기를 형성한 다음, 댐핑 돌기의 외측에 댐핑 고무를 장착하여 진동을 흡수함으로써, 차량의 조정 안정성을 증대시키는 효과를 갖는다.According to the present invention as described above, by reducing the diameter of a portion of the center link to form a plurality of damping protrusions, by mounting the damping rubber on the outside of the damping protrusions to absorb vibrations, thereby improving the adjustment stability of the vehicle Have
