본 발명은 토션빔 액슬의 스핀들 마운팅 구조에 관한 것으로서, 보다 상세하게는 스핀들이 토션빔 액슬에 마운팅되는 상태의 변화에 의해서 후륜의 토우(toe)를 조절할 수 있도록 하는 기술에 관한 것이다.The present invention relates to a spindle mounting structure of a torsion beam axle, and more particularly, to a technique for adjusting the toe of the rear wheel by a change in the state in which the spindle is mounted on the torsion beam axle.

토션빔 액슬은 소형 전륜구동차량의 후륜에 많이 사용되는 현가장치로서, 좌우의 아암이 빔에 의해 연결되어 있어서, 차체의 롤링에 따라 상기 빔이 비틀어지면서 스태빌라이저의 효과를 발휘하는 특징이 있다.The torsion beam axle is a suspension device that is frequently used for the rear wheels of small front-wheel drive vehicles, and the left and right arms are connected by beams, and the beams are twisted according to the rolling of the vehicle body.

그런데, 상기한 바와 같은 토션빔 액슬은 차량의 조립후에는 토우 조절이 불가능한 구조여서, 토션빔의 제조시 특정되는 얼라인먼트의 정확도가 차량의 주행성능을 크게 좌우하는 경향이 있다.However, the torsion beam axle as described above has a structure in which the tow adjustment is impossible after assembling the vehicle, and thus the alignment accuracy specified at the time of manufacture of the torsion beam tends to greatly influence the running performance of the vehicle.

또한, 어떤 이유에서 주행중이던 차량의 얼라인먼트가 맞지 않게 된 경우에는 토우의 조절이 불가능하므로 토션빔 액슬 전체를 교환해야 하는 문제점이 있다.In addition, when the alignment of the vehicle, which is being driven for some reason, does not match, the tow may not be adjusted, and thus the entire torsion beam axle may need to be replaced.

이에 본 발명은 상기한 바와 같은 문제점을 해결하기 위하여 안출된 것으로서, 토션빔 액슬에서 차륜의 토우값을 용이하게 조절할 수 있도록 하여, 차량의 최적 주행성능을 손쉽게 확보할 수 있도록 하고, 불필요한 부품의 교체를 방지하여 자원의 낭비를 억제하며 정비성이 향상되도록 한 토션빔 액슬의 스핀들 마운팅 구조를 제공함에 그 목적이 있다. Accordingly, the present invention has been made to solve the above problems, it is possible to easily adjust the toe value of the wheel in the torsion beam axle, to easily ensure the optimum running performance of the vehicle, replacement of unnecessary parts The purpose of the present invention is to provide a spindle mounting structure of a torsion beam axle that prevents waste, thereby suppressing waste of resources, and improves maintainability.

상기한 바와 같은 목적을 달성하기 위한 본 발명 토션빔 액슬의 스핀들 마운팅 구조는 토션빔 액슬의 아암에 고정된 스핀들고정브라켓과;Spindle mounting structure of the torsion beam axle of the present invention for achieving the above object is a spindle fixing bracket fixed to the arm of the torsion beam axle;

상기 스핀들고정브라켓에 면접한 상태로 고정되도록 스핀들에 구비된 스핀들고정판과;A spindle fixing plate provided on the spindle to be fixed in an interview state with the spindle fixing bracket;

상기 스핀들고정판이 스핀들의 회전축을 중심으로 회전되면서 상기 스핀들고정브라켓에 결합되는 각도에 따라 상기 스핀들고정브라켓에 대한 스핀들의 회전축 상태가 가변되도록 상기 스핀들고정판과 스핀들고정브라켓 사이에 구비된 편향수단을 포함하여 구성된 것을 특징으로 한다.And a deflection means provided between the spindle fixing plate and the spindle fixing bracket so that the state of the rotation axis of the spindle with respect to the spindle fixing bracket varies according to the angle at which the spindle fixing plate is rotated about the axis of rotation of the spindle. Characterized in that configured.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

도 1은 본 발명에 따른 토션빔 액슬의 스핀들 마운팅 구조의 일 실시예를 도시한 것으로서, 토션빔 액슬의 아암(1)에 고정된 스핀들고정브라켓(3)과, 상기 스핀들고정브라켓(3)에 면접한 상태로 고정되도록 스핀들(5)에 구비된 스핀들고정판(7)과, 상기 스핀들고정판(7)이 스핀들의 회전축을 중심으로 회전되면서 상기 스핀들고정브라켓(3)에 결합되는 각도에 따라 상기 스핀들고정브라켓(3)에 대한 스핀들의 회전축 상태가 가변되도록 상기 스핀들고정판(7)과 스핀들고정브라켓(3) 사이에 구비된 편향수단을 포함하여 구성된다.Figure 1 shows an embodiment of the spindle mounting structure of the torsion beam axle according to the invention, the spindle fixing bracket (3) fixed to the arm (1) of the torsion beam axle, and the spindle fixing bracket (3) The spindle fixing plate 7 provided on the spindle 5 to be fixed in an interviewed state, and the spindle fixing plate 7 is rotated about the axis of rotation of the spindle while being coupled to the spindle fixing bracket 3 while being rotated about the spindle axis. It comprises a deflection means provided between the spindle fixing plate 7 and the spindle fixing bracket (3) so that the rotation axis state of the spindle relative to the fixed bracket (3).

본 실시예에서, 상기 편향수단은 스핀들의 회전축에 수직한 면에 대해 경사진 평면으로 상기 스핀들고정판(7)에 형성된 스핀들경사평면(9)과, 스핀들의 회전축에 수직한 면에 대해 경사진 평면으로 상기 스핀들고정브라켓(3)에 형성된 브라켓경사평면(11)을 포함하여 구성하였다.In this embodiment, the biasing means is a plane inclined plane 9 formed on the spindle fixing plate 7 in a plane inclined with respect to a plane perpendicular to the axis of rotation of the spindle, and a plane inclined with respect to a plane perpendicular to the axis of rotation of the spindle. It was configured to include a bracket inclined plane 11 formed on the spindle fixing bracket (3).

한편, 상기 스핀들고정판(7)과 스핀들고정브라켓(3)에는 이들을 관통하여 체결되는 체결볼트들을 위한 볼트구멍(13)이 4개가 동일한 원주상에 동일한 간격을 두고 형성되어 상기 스핀들고정브라켓(3)에 대하여 상기 스핀들고정판(7)을 90도 간격으로 회동시켜서 결합할 수 있도록 하였다.On the other hand, in the spindle fixing plate 7 and the spindle fixing bracket 3, four bolt holes 13 for fastening bolts fastened therethrough are formed at equal intervals on the same circumference, so that the spindle fixing bracket 3 The spindle fixing plate 7 was rotated at intervals of 90 degrees with respect to the coupling.

상기 스핀들고정판(7)을 스핀들고정브라켓(3)에 대하여 회동시켜서 장착하는 상태에 의해서 토우가 변화하게 되므로, 토우의 미세한 조절을 위해서 상기 볼트구멍(13)을 보다 많이 형성할 수도 있다.Since the tow is changed by the state in which the spindle fixing plate 7 is rotated with respect to the spindle fixing bracket 3 and mounted, the bolt hole 13 may be formed more for fine adjustment of the tow.

상기한 바와 같이 구성된 본 발명의 작용을 살펴보면 다음과 같다.Looking at the operation of the present invention configured as described above are as follows.

상기 스핀들고정판(7)을 상기 스핀들고정브라켓(3)에 대하여 스핀들의 회전축을 중심으로 회동시킨 상태로 고정하면, 회동전의 고정상태와 회동후의 고정상태 사이에는 토우의 변화가 수반된다.When the spindle fixing plate 7 is fixed with the spindle fixing bracket 3 rotated about the rotation axis of the spindle, a change in the tow is accompanied between the fixed state before the rotation and the fixed state after the rotation.

즉, 상기 스핀들고정판(7)을 상기 스핀들고정브라켓(3)에 대하여 회동시켜서 고정하면, 스핀들고정판(7)에 구비된 스핀들경사평면(9)과 상기 스핀들고정브라켓(3)에 구비된 브라켓경사평면(11)이 서로 마주 접촉한 상태가 변화하게 되어, 결과적으로 스핀들고정판(7)과 일체로 구성되어 있는 스핀들의 회동축이 상기 스핀들고정브라켓(3)에 대하여 변화됨으로써, 토우가 변화되는 것이다.That is, when the spindle fixing plate 7 is rotated and fixed with respect to the spindle fixing bracket 3, the bracket inclined plane 9 provided on the spindle fixing plate 7 and the bracket inclination provided on the spindle fixing bracket 3 are fixed. The state in which the planes 11 are in contact with each other changes, and as a result, the rotational axis of the spindle integrally formed with the spindle fixing plate 7 changes with respect to the spindle fixing bracket 3, thereby changing the tow. .

도 2에는 상기 스핀들고정판(7)을 스핀들고정브라켓(3)에 대하여 회동시킬 수 있는 상태를 도시하고 있으며, 그 회동되는 방향에 따라서 리어휠의 토우인과 토우아웃이 형성될 수 있음을 표현하고 있다.FIG. 2 shows a state in which the spindle fixing plate 7 can be rotated with respect to the spindle fixing bracket 3, and expresses that the toe-in and the toe-out of the rear wheel can be formed according to the direction in which the spindle fixing plate 7 is rotated. .

따라서, 토우를 조절하고자 할 때에는 도 2에 도시된 바와 같이 스핀들고정판(7)을 스핀들고정브라켓(3)에 고정하는 체결볼트들을 풀고 스핀들고정판(7)을 원하는 방향으로 회동시킨 후 다시 체결볼트들을 체결함으로써, 간단하게 토우를 조절할 수 있게 된다.Therefore, when adjusting the tow, loosen the fastening bolts for fixing the spindle fixing plate 7 to the spindle fixing bracket 3 as shown in FIG. 2, rotate the spindle fixing plate 7 in the desired direction, and then tighten the fastening bolts again. By tightening, the toe can be adjusted simply.

물론, 이때 캠버의 변화도 수반되지만, 본 발명의 기본 전제가 되고 있는 토션빔 액슬 타입의 서스펜션에서는 상기 캠버 변화의 양은 차량의 주행특성에 큰 영향을 주지 않으므로 큰 문제가 되지 않는다.Of course, the change of the camber is also involved, but in the torsion beam axle type suspension, which is the basic premise of the present invention, the amount of change of the camber does not have a great influence on the running characteristics of the vehicle.

한편, 상기한 바와 같이 토우의 조절을 위해 상기 스핀들고정판(7)과 스핀들고정브라켓(3) 양측에 모두 각각 스핀들경사평면(9)과 브라켓경사평면(11)을 설치하지 않고, 어느 일측은 종래와 같이 단순평면으로 구성하고 상기 스핀들경사평면(9) 또는 브라켓경사평면(11)을 선택적으로 형성하여도, 상기한 바와 같은 방법으로 토우의 조절이 가능하다. On the other hand, as described above, the spindle inclined plane 9 and the bracket inclined plane 11 are not provided on both sides of the spindle fixing plate 7 and the spindle fixing bracket 3, respectively. As described above, even if the spindle inclined plane 9 or the bracket inclined plane 11 is formed selectively, the tow can be adjusted in the same manner as described above.

이상과 같이 본 발명에 의하면, 토션빔 액슬에서 차륜의 토우값을 용이하게 조절할 수 있도록 하여, 차량의 최적 주행성능을 손쉽게 확보할 수 있도록 하고, 불필요한 부품의 교체를 방지하여 자원의 낭비를 억제하며 정비성이 향상되도록 한다. As described above, according to the present invention, it is possible to easily adjust the toe value of the wheel in the torsion beam axle, to easily ensure the optimum running performance of the vehicle, and to prevent waste of resources by preventing the replacement of unnecessary parts Ensure maintainability.
