Abstract

주행조건에 따라 캠버 및 트레드의 변화를 휠의 범프 및 리바운드 전구간에 걸쳐서 가장 이상적으로 제어하여 선회시 선회 안정성을 향상시키고, 직진시 승차감은 물론 직진 주행 안전성을 향상시킬 수 있는 자동차의 현가장치에 관한 것으로서, 휠을 회전 가능하게 지지하는 너클과 ; 쇽 업소오버와 스프링의 조립체로 형성되어 그의 하단이 휠을 회전 가능하게 지지하는 너클과 일체로 형성되고 상단이 차체에 지지되는 완충기구인 스트러트 어셈블리와 ; 상기 너클의 하측을 차체 또는 서브 프레임과 연결하여 주는 로워 컨트롤 링크와 ; 그리고 상기 로워 컨트롤 링크의 차체측단 연결부에 개재되어 로워 컨드롤 링크의 상향 회동시 로워 컨트롤 링크의 차체측단을 로워 컨트롤 링크의 휠측단을 중심으로 하는 원호방향 상하로 이 컨트롤 링크의 일정점을 중심으로 가이드 함으로써 이 로워아암을 외측으로 밀어주어 휠의 캠버를 제어하는 캠버제어수단을 포함하여 이루어짐을 특징으로 하는 차량용 현가장치를 제공한다.Ideally controlling the change of camber and tread over the bump and rebound of the wheel according to the driving conditions to improve the turning stability when turning, and to improve the riding comfort as well as driving safety when going straight. A knuckle rotatably supporting the wheel; A strut assembly formed of an assembly of a shock absorber and a spring, the lower end of which is integrally formed with a knuckle for rotatably supporting the wheel, and the upper end being a shock absorbing mechanism supported by the vehicle body; A lower control link connecting the lower side of the knuckle to a vehicle body or subframe; And interposed between the body side end connection of the lower control link and the body side end of the lower control link in the arc direction up and down around the wheel side end of the lower control link when the lower control link is rotated upward. It provides a suspension device for a vehicle comprising a camber control means for controlling the camber of the wheel by pushing the lower arm to the outside by guiding.

Claims

A knuckle for rotatably supporting the wheel; A strut assembly formed of an assembly of a shock absorber and a spring, the lower end of which is integrally formed with a knuckle for rotatably supporting the wheel, and the upper end being a shock absorbing mechanism supported by the vehicle body; A lower control link connecting the lower side of the knuckle to a vehicle body or subframe; It is interposed between the body side end connection part of the lower control link and guides the body side end of the lower control link up and down in a circular arc direction about the wheel side end of the lower control link when the upper side of the lower control link rotates. And a camber control means for pushing the lower arm to the outside to control the camber of the wheel.

The method of claim 1, wherein the camber control means; A bracket having one end fixed to the vehicle body or subframe by a predetermined fixing means; A first slot formed at a wheel side end of the bracket and inserted to protrude outward from a first guide protrusion formed integrally with the control link; And a second slot formed at an inner end of the bracket and inserted into the second guide protrusion which is integrally formed with the connection shaft of the inner connection portion of the control link to protrude outward.

The vehicle suspension system according to claim 2, wherein the first slot has a predetermined length in the same direction as the axial direction of the front end lower control link of the bracket.

3. The vehicle suspension according to claim 2, wherein the second slot has an arc shape having a radius smaller than a radius of rotation of the link centered on the wheel side connection portion of the control link 2 inside the bracket. .

A vehicle suspension formed of a plurality of links, comprising: a bracket having one end fixed to a vehicle body or a surf frame by predetermined fixing means; A first guide protrusion integrally formed with the vehicle body side connection part shaft of the control link; A second guide protrusion integrally formed at a predetermined portion of the control link; A first slot formed at a vehicle body side end of the bracket and inserted such that the first protrusion protrudes outward of the bracket so that the wheel guides the control link during vertical vibration and pushes and pulls the link in the axial direction; And a second slot formed at the wheel side end of the bracket, wherein the wheel includes a second slot that suppresses the movement of the control link in the vertical direction of the axis of the control link while acting as the center of rotation of the control link. Control link mounting structure of the device.

6. The control link mounting structure of claim 5, wherein the second slot has a predetermined length at a distal end of the bracket in the same direction as the axial direction of the lower control link.

The control link of claim 5, wherein the first slot has an arc shape having a radius smaller than a radius of rotation of the link centered on a wheel-side connection portion of the control link inside the bracket. Mounting structure.
