The present invention relates to the lower pad of a coil spring for a vehicle suspension, which is installed between a lower sheet, which accommodates and supports the lower portion of the coil spring, and the lower portion of the coil spring to prevent damage to the lower sheet, and which has a seating groove formed at the top thereof so that the lower surface of the coil spring is seated thereon. A spring pitch non-behavior portion in which a coil spring pitch is maintained is formed in a seating groove section in a direction in which the tip of the coil spring is disposed. A spring pitch behavior portion in which the coil spring pitch changes is formed in a portion of the seating groove section excluding the spring pitch non-behavior portion. The spring pitch non-behavior portion has a section in which a pitch profile defined by the height of the seating groove decreases in the disposition direction of the tip of the coil spring. The pitch profile of the spring pitch behavior portion increases in response to the gap between the lower surface of the coil spring and the lower sheet according to the spiral winding shape of the coil spring. At the boundary between the spring pitch non-behavior portion and the spring pitch behavior portion, a pitch profile for each seating groove section is formed so that a pitch profile maintenance section in which the pitch profile is maintained constant is formed.

    본 발명은 코일스프링의 하부를 수용하여 지지하는 하부시트의 손상을 방지하도록 상기 하부시트와 코일스프링의 하부 사이에 설치되어, 코일스프링의 하부면이 안착되도록 상부에 안착홈이 형성된 차량 현가장치용 코일스프링 하부패드에 관한 것이다. 코일스프링의 선단부가 배치되는 방향의 안착홈 구간에 코일스프링 피치가 유지되는 스프링 피치 비거동부가 형성되고, 스프링 피치 비거동부 외 안착홈 구간에 코일스프링 피치 변화가 발생하는 스프링 피치 거동부가 형성되되, 상기 스프링 피치 비거동부는 코일스프링의 선단부 배치 방향에 안착홈 높이로 정의되는 피치 프로파일이 감소하는 구간이 형성되고, 상기 스프링 피치 거동부는 코일스프링의 나선 권취형상에 따라 코일스프링 하부면과 하부시트간 간격에 대응하여 피치 프로파일이 증가하며, 스프링 피치 비거동부와 스프링 피치 거동부의 경계부에는 피치 프로파일이 일정하게 유지 되는 피치 프로파일 유지 구간이 형성되도록 안착홈 구간별 피치 프로파일이 형성된다.
