Description

차량의 휠각도 조절장치Vehicle wheel angle control device

본 발명은 차량의 휠각도 조절장치에 관한 것으로서, 보다 상세하게는 차량의 앞바퀴를 주행방향과 일렬이 되도록 하여 차량의 주행 안정성 및 연비를 향상시키도록 하는 차량의 휠각도 조절장치에 관한 것이다.The present invention relates to a wheel angle control device of a vehicle, and more particularly, to a wheel angle control device of a vehicle to improve the running stability and fuel efficiency of the vehicle by making the front wheel of the vehicle aligned with the driving direction.

차량은 휠에 구동력을 공급함으로써 휠의 회전으로 움짐이게 된다. 휠에 구동력을 전달시키고 휠을 차체에 고정시키게 되는데 어떻게 부착되어 있는가를 나타내는 것으로 휠얼라인먼트라고 한다.The vehicle is moved by the rotation of the wheel by supplying driving force to the wheel. The driving force is transmitted to the wheel and the wheel is fixed to the vehicle body.

휠얼라인먼트는 타이어가 노면과의 관계에서 킹핀경사각, 캠버, 캐스터, 토인의 4개 요소를 가리키는 것으로써 자동차의 주행안정성, 조종성, 타이어 마모 등에 큰 영향을 준다. 그리고 휠얼라인먼트는 자동차의 자세나 부하에 의하여 변화하므로 자동차를 수평면에 두고 직진 상태에서 정지했을 때의 수치로써 나타낸다.Wheel alignment refers to the four elements of the kingpin inclination, camber, caster, and toe in relation to the road surface, which greatly affects driving stability, maneuverability, and tire wear. Since wheel alignment changes according to the attitude and load of the vehicle, the wheel alignment is expressed as a value when the vehicle is stopped in a straight state with the vehicle in a horizontal plane.

그런데, 차량의 주행방향과 휠이 일직선상에 위치하지 않을 경우에도 운전자가 알기가 어려울 뿐만 아니라 만약 알았다고 하더라도 정비소에 가서 휠얼라인먼트를 측정하여 재조정해야만 한다는 문제점이 있다.However, even when the driving direction of the vehicle and the wheel are not located in a straight line, it is difficult for the driver to know, and even if it is known, there is a problem in that the wheel alignment should be measured and readjusted if it is known.

본 발명은 상기와 같은 문제점을 해결하기 위해 창작된 것으로서, 본 발명의 목적은 차량의 앞바퀴를 주행방향과 일렬이 되도록 휠각도를 조절하는 차량의 휠각도 조절장치를 제공함에 있다.The present invention has been made to solve the above problems, and an object of the present invention is to provide a wheel angle adjusting device of a vehicle for adjusting the wheel angle so that the front wheel of the vehicle is aligned with the driving direction.
