차량의 서스펜션 구조{suspension structure of a vehicle}Suspension structure of a vehicle

본 발명은 차량의 서스펜션 구조에 관한 것으로서, 보다 상세하게는 트레드의 변화가 없는 차량의 서스펜션 구조에 관한 기술이다.The present invention relates to a suspension structure of a vehicle, and more particularly, to a technique of a suspension structure of a vehicle without a change in tread.

종래의 현가장치는 휠이 차체에 대하여 상하로 이동할 때, 차량의 폭방향으로 휠의 변위가 수반되는 구조를 가지고 있다.The conventional suspension has a structure in which wheel displacement is accompanied in the width direction of the vehicle when the wheel moves up and down with respect to the vehicle body.

상기한 바와 같이 휠의 차체에 대한 상하 운동시에 휠의 차량 폭방향 변위가 수반되면, 양쪽 차륜 사이의 거리인 트레드가 변화하게 된다.As described above, if the wheel widthwise displacement of the wheel is accompanied during the vertical movement of the wheel body, the tread, which is the distance between both wheels, changes.

상기한 바와 같이 차량의 주행중에 트레드가 변화하면, 이에 따라 휠얼라인먼트가 매 순간 변화하면서 차량의 직진안정성 및 선회안정성에 악영향을 미치게 된다.As described above, if the tread changes while the vehicle is running, the wheel alignment is changed every moment, which adversely affects the linear stability and the turning stability of the vehicle.

본 발명은 차량의 주행중 휠의 차체에 대한 상하방향 운동 발생시에도 휠의 차폭방향 변위가 발생하지 않도록 함으로써, 휠얼라인먼트가 안정적으로 유지될 수 있도록 하여 차량의 직진안정성 및 선회안정성을 확보할 수 있도록 한 차량의 서스펜션 구조를 제공함에 그 목적이 있다.According to the present invention, wheel displacement is prevented from occurring even when the vehicle moves up and down with respect to the body of the wheel while driving, so that wheel alignment can be stably maintained, thereby ensuring straightness and turning stability of the vehicle. The purpose is to provide a suspension structure of a vehicle.

상기한 바와 같은 목적을 달성하기 위한 본 발명 차량의 서스펜션 구조는Suspension structure of the vehicle of the present invention for achieving the above object is

차체의 길이방향을 따르는 수직평면과 평행하게 상하로 배치된 직선가이드로드와;A linear guide rod disposed up and down in parallel with the vertical plane along the longitudinal direction of the vehicle body;

을 포함하여 구성된 것을 특징으로 한다.Characterized in that configured to include.

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 1을 참조하면, 본 발명 차량의 서스펜션 구조는 차체(1)의 길이방향을 따르는 수직평면과 평행하게 상하로 배치된 직선가이드로드(3)와; 상기 직선가이드로드(3)에 슬라이딩 가능하게 끼워지고 휠(5)이 고정되는 슬라이더(7)와; 상기 슬라이더(7)와 차체(1) 사이에 설치되며 상기 직선가이드로드(3)와 평행하게 배치되는 쇽업소버(9)와; 상기 슬라이더(7)가 차체(1)의 하측으로 탄성 지지되도록 설치된 스프링(11)을 포함하여 구성되어 있다.1, the suspension structure of the vehicle of the present invention includes a straight guide rod (3) disposed up and down in parallel with the vertical plane along the longitudinal direction of the vehicle body (1); A slider (7) slidably fitted to the straight guide rod (3) and fixed with a wheel (5); A shock absorber (9) disposed between the slider (7) and the vehicle body (1) and disposed in parallel with the straight guide rod (3); The slider 7 is configured to include a spring 11 provided to elastically support the lower side of the vehicle body 1.

여기서, 상기 직선가이드로드(3)가 차체(1)의 길이방향을 따르는 수직평면과 평행하게 상하로 배치되었다는 것은, 차체(1)의 전방이나 후방에서 상기 직선가이드로드(3)를 보면 차체(1)로부터 수직하게 상하로 설치되어 있고, 차체(1)의 측방에서 보면 도 2에 도시된 바와 같이 기울어져서 캐스터를 형성할 수 있도록 배치된다는 것을 의미한다.Here, the straight guide rod (3) is arranged up and down in parallel with the vertical plane along the longitudinal direction of the vehicle body 1, when looking at the straight guide rod (3) in front or rear of the vehicle body (1) It is provided vertically up and down from 1), and it is arranged so that it can be inclined to form a caster as shown in FIG. 2 when viewed from the side of the vehicle body 1.

상기 직선가이드로드(3)의 상/하단 및 상기 쇽업소버(9)의 상단은 마운팅부시(14)에 의해 차체(1)와 결합되고, 상기 쇽업소버(9)의 상측에는 쇽업소버(9)의 외통이 차체(1)에 직접 접촉하는 것을 방지하기 위한 범퍼스토퍼(13)가 설치되어 있다.The upper / lower end of the straight guide rod 3 and the upper end of the shock absorber 9 are coupled to the vehicle body 1 by a mounting bush 14, and the shock absorber 9 is located above the shock absorber 9. The bumper stopper 13 for preventing the outer cylinder from directly contacting the vehicle body 1 is provided.

상기 스프링(11)은 상기 직선가이드로드(3)의 외측에 삽입되고, 상기 스프링(11)의 상측에는 상기 스프링(11)의 상단이 직접 차체(1)의 하측에 접촉되는 것을 방지하기 위한 스프링시트(15)가 구비되어 있는 구조이다.The spring 11 is inserted to the outside of the straight guide rod 3, a spring for preventing the upper end of the spring 11 directly in contact with the lower side of the vehicle body 1 on the upper side of the spring (11). It is a structure provided with the sheet | seat 15.

한편, 상기 슬라이더(7)에는 유체베어링(17)을 장착하여, 상기 유체베어링(17)이 상기 직선가이드로드(3)와 직접 접촉하도록 함으로써, 보다 원활한 슬라이딩운동이 이루어질 수 있도록 하는 것이 바람직하다.On the other hand, it is preferable that the slider 7 is equipped with a fluid bearing 17 so that the fluid bearing 17 is in direct contact with the linear guide rod 3, so that a more smooth sliding movement can be achieved.

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.

차량이 주행중에 노면의 변화와 차체(1)의 거동변화 등에 의해 휠(5)과 차체(1) 사이에 작용하는 힘이 변화되어, 휠(5)이 차체(1)에 대하여 상하방향으로 운동하게 된다.The force acting between the wheel 5 and the vehicle body 1 is changed by the change of the road surface and the behavior of the vehicle body 1 while the vehicle is running, so that the wheel 5 moves up and down with respect to the vehicle body 1. Done.

휠(5)이 차체(1)에 대하여 상측으로 이동하도록 힘을 받으면, 상기 휠(5)에 일체로 연결된 슬라이더(7)는 상기 직선가이드로드(3)를 따라서 상측으로 직선 슬라이딩하게 된다.When the wheel 5 is forced to move upward with respect to the vehicle body 1, the slider 7 integrally connected to the wheel 5 is linearly slid upward along the straight guide rod 3.

상기와 같이 슬라이더(7)가 직선가이드로드(3)를 따라 상승하면, 상기 슬라이더(7)의 상측에 설치된 스프링(11)은 상기 슬라이더(7)의 상승을 탄성력으로 저지하면서 상기 슬라이더(7)로부터 전달되는 힘을 완충하고, 상기 슬라이더(7)와 일체로 연결된 쇽업소버(9)는 압축되면서 상기 슬라이더(7)로부터의 힘을 감쇠시키게 된다.When the slider 7 rises along the linear guide rod 3 as described above, the spring 11 installed on the upper side of the slider 7 stops the rise of the slider 7 with an elastic force and the slider 7 The shock absorber 9, which is integral with the slider 7, absorbs the force transmitted from the damper, and compresses the force from the slider 7.

잠시후 상기 슬라이더(7)가 제공하는 힘보다 상기 스프링(11)에 축적되는 탄성에너지가 강해지면, 상기 슬라이더(7)는 상기 스프링(11)의 힘에 의해 다시 상기 직선가이드로드(3)를 따라 하측으로 직선 슬라이딩하게 되며, 이때에서 상기 쇽업소버(9)는 상기 스프링(11)의 힘으로 하측으로 슬라이딩하는 슬라이더(7)의 운동에너지를 감쇠시키게 된다.After a while, when the elastic energy accumulated in the spring 11 becomes stronger than the force provided by the slider 7, the slider 7 again pulls the straight guide rod 3 by the force of the spring 11. Therefore, the linear sliding to the lower side, in this case the shock absorber (9) to attenuate the kinetic energy of the slider (7) sliding downward by the force of the spring (11).

이때, 상기한 바와 같은 슬라이더(7)의 상하 운동은 상기 직선가이드로드(3) 상에서만 이루어지게 되고, 상기 직선가이드로드(3)는 차폭방향으로는 기울어져있지 않으므로, 상기 휠(5)의 상하운동은 차폭방향의 변위를 수반하지 않게 된다.At this time, the vertical movement of the slider 7 as described above is made only on the linear guide rod 3, the linear guide rod 3 is not inclined in the vehicle width direction, so that the wheel 5 The vertical motion does not involve displacement in the vehicle width direction.

따라서 결과적으로 휠(5)의 상하 운동에 대하여 트레드의 변화가 없게 되어, 휠(5)얼라인먼트의 부적절한 변화가 방지되게 되어, 차량의 직진안정성 및 선회안정성을 확보할 수 있게 된다.As a result, there is no change in the tread with respect to the up and down movement of the wheel 5, thereby preventing the improper change of the wheel 5 alignment, thereby ensuring the straightness and turning stability of the vehicle.

이상과 같이 본 발명에 의하면, 차량의 주행중 휠의 차체에 대한 상하방향 운동 발생시에도 휠의 차폭방향 변위가 발생하지 않도록 함으로써, 휠얼라인먼트가 안정적으로 유지될 수 있도록 하여 차량의 직진안정성 및 선회안정성을 확보할 수 있도록 한다. As described above, according to the present invention, the wheel alignment can be stably maintained by preventing wheel displacement in the vehicle width direction even when vertical motion of the wheel is generated while driving the vehicle, so that the wheel alignment can be stably maintained. To be secured.
