방진고무가 부착된 조향 드래그링크{A DRAG LINK WHICH IS ADHERED BY A RUBBER}DRAG LINK WHICH IS ADHERED BY A RUBBER

본 발명은 방진고무가 부착된 조향 드래그링크에 관한 것으로, 보다 상세하게는 드래그링크의 엔드링 내주연에 방진고무를 장착함으로써, 노면으로부터 전달되는 충격이나 조향장치 자체의 진동을 흡수하여 조정 안정성을 증대시킬 수 있도록 한 방진고무가 부착된 조향 드래그링크에 관한 것이다.The present invention relates to a steering drag link with anti-vibration rubber, and more particularly, by attaching the anti-vibration rubber to the inner circumference of the end ring of the drag link, absorbing the shock transmitted from the road surface or the vibration of the steering device itself to improve the adjustment stability. The present invention relates to a steering drag link with anti-vibration rubber, which can be increased.

일반적으로, 조향장치는 자동차의 진행방향을 임의로 변경하기 위해 사용하는 장치로서, 조향휠(1)과 같은 조작기구와, 조작기구의 운동방향을 바꾸는 기어박스(4) 및 기어박스(4)의 작동을 조향륜(10, 10')에 직접 전달하는 링크기구로 구분할 수 있다.In general, the steering apparatus is a device used to arbitrarily change the traveling direction of a vehicle, and includes a steering mechanism such as a steering wheel 1 and a gear box 4 and a gear box 4 for changing the movement direction of the steering mechanism. It can be distinguished by a link mechanism which transmits the operation directly to the steering wheels 10 and 10 '.

도 1은 일반적인 자동차용 조향장치의 구성을 보인 개략도로서, 운전자가 조향휠(1)을 회전시키면 조향휠(1)의 조작력은 조향칼럼(2) 내에 장착된 조향축(3)을 통해 기어박스(4)로 전달되며, 기어박스(4)는 조향축(3)의 회전을 감속하여 조작력을 증대시킴과 동시에, 조작기구의 운동방향을 바꾸어 피트먼 아암(5) 및 드래그링크(6)를 거쳐 중심링크(7)로 전달한다.1 is a schematic view showing the configuration of a general steering device for a vehicle, when the driver rotates the steering wheel 1, the operating force of the steering wheel (1) through the steering shaft (3) mounted in the steering column (2) gearbox (4), the gear box (4) to reduce the rotation of the steering shaft (3) to increase the operating force, and at the same time change the direction of movement of the operating mechanism to move the pitman arm (5) and the drag link (6) Transfer to the center link (7) through.

중심링크(7)는 드래그링크(6)를 통해 전달된 조향휠(1)의 조작력을 타이로드(8, 8')로 전달하는 것으로, 타이로드(8, 8')로 전달된 조작력에 의해 너클 스핀들(9, 9')을 움직이게 된다.The center link 7 transmits the operating force of the steering wheel 1 transmitted through the drag link 6 to the tie rods 8 and 8 'and is controlled by the operating force transmitted to the tie rods 8 and 8'. The knuckle spindles 9 and 9 'are moved.

너클 스핀들(9, 9')의 움직임에 따라 조향륜(10, 10')은 킹핀을 중심으로 하는 회전운동을 하면서 진행방향을 변경할 수 있다.According to the movement of the knuckle spindles 9 and 9 ', the steering wheels 10 and 10' can change the traveling direction while making a rotational movement about the kingpin.

그러나, 상기와 같은 종래의 자동차용 조향장치는 강성을 지닌 하나의 축으로 구성되어 있기 때문에, 요철이 심한 노면으로부터 전달되는 충격이나 조향장치 자체의 진동을 흡수할 수 없으므로, 이로 인해 발생되는 시미(SHIMMY)현상 및 킥백(KICK BACK)현상에 의해 진동현상이 발생되어 운전자의 조향력을 저감시킴은 물론 실내소음의 원인이 되는 문제점이 있었다.However, the conventional steering device for vehicles as described above is composed of a single shaft having rigidity, so that the bumps and bumps transmitted from the rough road surface or the vibration of the steering device itself cannot be absorbed. SHIMMY) Vibration occurs due to the phenomenon of kickback and kickback, which reduces the driver's steering power as well as causing noise in the room.

본 발명은 상술한 바와 같은 종래 기술이 갖는 제반 문제점을 감안하여 이를 해결하고자 창출한 것으로, 드래그링크에 볼스터드와 엔드링 사이에 방진고무를 개재하여 타이어의 불균형성에 의해 발생되는 조정장치의 진동현상인 시미현상과 한쪽 타이어의 충격시 발생되는 조향장치의 쇼크 및 진동현상인 킥백현상을 저감시키도록 한 방진고무가 부착된 조향 드래그링크를 제공함에 그 목적이 있다.The present invention was created in view of the above-described problems of the prior art, and solved this problem. The vibration phenomenon of the adjustment device caused by unbalanced tires is provided through the dustproof rubber between the ball stud and the end ring in the drag link. It is an object of the present invention to provide a steering drag link with anti-vibration rubber to reduce kickback phenomenon, which is a shock and vibration phenomenon of a steering system generated when an in-siting phenomenon and a shock of one tire are generated.

먼저, 도 1에서 설명한 바와 같이, 운전자가 조향휠(1)을 회전시켜면, 기어박스(4)를 통해 전달되는 조향휠(1)의 회전수를 감속하여 토오크를 증대시킨 다음에, 증대된 조작력을 피트먼 아암(5) 및 드래그링크(6)로 전달하게 되며, 드래그링크(6)로 전달된 힘은 중심링크(7)와 타이로드(8, 8')를 통해 너클 스핀들(9, 9')로 전달되며, 너클 스핀들(9, 9')은 킹핀을 중심으로 조향륜(10, 10')을 회전시켜 차량의 진행방향을 변경할 수 있게 된다.First, as described in FIG. 1, when the driver rotates the steering wheel 1, the torque is decreased by increasing the torque by decelerating the rotation speed of the steering wheel 1 transmitted through the gearbox 4, and then increasing the torque. The operating force is transmitted to the pitman arm 5 and the drag link 6, and the force transmitted to the drag link 6 is transferred to the knuckle spindle 9, through the center link 7 and the tie rods 8, 8 ′. 9 '), the knuckle spindles 9 and 9' rotate the steering wheels 10 and 10 'around the kingpin to change the direction of travel of the vehicle.

또한, 본 발명에서는 노면으로부터 전달되는 충격이나 조향장치 자체의 진동을 감쇠하기 위한 방안으로, 드래그링크(6)의 볼스터드(14)와 엔드링(15) 접합부 사이에 진동을 감쇠시키는 방진고무(16)를 개재시켜 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 anti-vibration rubber for damping the vibration between the ball stud 14 and the end ring 15 of the drag link 6 ( Adjustment stability was improved through 16). This will be described in the following FIG. 3.

도시된 바와 같이, 드래그링크(6)와 연결되는 소켓부(17)에는 내측에 스프링(11)이 탄설되어 스프링시트(12)에 의해 지지되고 이 스프링시트(12) 양측으로는 볼시트(13)가 형성되며, 이와 같이 상기 볼시트(13)가 형성된 공간에는 볼스터드(14)가 내설된다.As shown in the drawing, the socket portion 17 connected to the drag link 6 has a spring 11 mounted therein and supported by the spring sheet 12 and the ball seat 13 on both sides of the spring sheet 12. ) Is formed, and the ball stud 14 is embedded in the space in which the ball sheet 13 is formed.

상기와 같이 구성된 소켓부(17)는 드래그링크(6)에 형성된 엔드링(15)의 내주연에 압축강도가 높은 방진고무(16)가 개재된 후 수직으로 내설된다.The socket 17 constructed as described above is vertically installed after the anti-vibration rubber 16 having a high compressive strength is interposed in the inner circumference of the end ring 15 formed in the drag link 6.

이러한 구성으로 이루어진 본 발명은 다음과 같이 방진된다.The present invention made of such a configuration is dustproof as follows.

노면에 접촉해 있는 조향륜(10, 10')으로부터 기진력이 너클 스핀들(9, 9')과 타이로드(8, 8')를 통해서 드래그링크(6)에 전달될 시 소켓부(17)에 탄설된 스프링(11)에 의해서 볼스터드(14)의 길이방향 기진력은 방진되고 좌우방향 기진력은 상기 드래그링크(6)의 엔드링(15)에 내설된 방진고무에 의해서 방진된다.Socket portion 17 when vibration force is transmitted from the steering wheel 10, 10 ′ in contact with the road surface to the drag link 6 through the knuckle spindles 9, 9 ′ and tie rods 8, 8 ′. The longitudinal vibration force of the ball stud 14 is oscillated by the spring 11 mounted on the dust, and the lateral vibration force is oscillated by the anti-vibration rubber in the end ring 15 of the drag link 6.

이때, 상기 볼스터드(14)의 길이방향 기진력은 좌우방향 기진력에 비해 상대적으로 매우 적기 때문에 방진고무(16)에서 소켓부(17)가 이탈되는 경우는 발생하지 않는다.At this time, since the longitudinal vibration force of the ball stud 14 is relatively less than the vibration force in the left and right directions, the socket part 17 is not separated from the anti-vibration rubber 16.

이상에서 상세히 설명한 바와 같이, 본 발명은 드래그링크의 엔드링 내주연에 압착된 방진고무의 방진에 의해 조향휠 조작시 조향링크부에 저절한 유격감이 형성되어 조향휠의 조작감이 향상됨은 물론, 차량의 조정 안정성을 증대시킬 수 있는 효과를 제공한다.As described in detail above, in the present invention, when the steering wheel is operated by the vibration prevention of the anti-vibration rubber compressed on the inner circumference of the drag ring, the relief link is formed in the steering link portion, thereby improving the operation feeling of the steering wheel. It provides an effect that can increase the steering stability of the vehicle.
