Disclosed is a caster characteristic adjustment apparatus for a vehicle. According to the present invention, a lower arm is divided into a lateral arm and a guide arm and is rotationally connected to each other, and a position of the lateral arm is changed by driving an actuator. Accordingly, driving performance is improved by changing a driving characteristic according to a driving mode by adjusting a caster characteristic. In addition, as unintentional rotational movement of a steering wheel is prevented when the caster characteristic is adjusted, unintentional fluctuations of the steering wheel are minimized, thereby maintaining the predetermined driving characteristic. The caster characteristic adjustment apparatus for the vehicle of the present invention comprises a variable lower arm and an actuator.
본 발명에서는 로워암이 래터럴암과 가이드암으로 구분되어 상호 회전 가능하게 연결되고, 래터럴암의 경우 액추에이터 구동에 의해 위치가 변경됨으로써, 캐스터 특성의 조절에 의해 주행모드에 따른 주행 특성이 변경되어 주행 성능이 향상된다. 또한, 캐스터 특성의 조절시 조향 휠의 의도치 않는 회전 운동이 방지됨에 따라 의도하지 않는 조향 휠의 변동이 최소화되어 정해진 주행 특성이 유지되도록 하는 차량용 캐스터 특성 조절장치가 소개된다.
