The present invention relates to a shock absorber for an automated guided vehicle (AGV) wheel, which comprises: a first support body (100) joined to the lower part of a vehicle frame to have a rotational shaft (110) in a horizontal direction; a wheel body unit (200) coupled with the rotational shaft to be able to rotate and have a wheel in the lower part; and a second support body (300) joined to the lower part of the vehicle frame to have a vertical shaft (310) where one end of the wheel body unit is joined to be able to move vertically, wherein the second support body (300) includes: a spring (S) coupled with the outer circumference of the shaft; a nut (320) and a spring mount member (330) coupled with the shaft, respectively, at the upper part and the lower part of the spring; a guide roller (340) disposed below the spring mount member to support the spring mount member; and a roller groove (334) formed on the bottom surface of the spring mount member, where the guide roller is seated. In accordance with the present invention, when the wheel body unit rotates on the rotational shaft, one end of the wheel body unit comes in contact with the guide roller and the spring is pressurized in a lengthwise direction. Accordingly, when an AGV forklift travels on an uneven road, the contraction force of a spring is applied to the spring in a lengthwise direction.
본 발명은 AGV의 휠의 완충장치에 대한 것으로, 차체하부에 결합되고 수평방향으로 회동축(110)을 구비하는 제1지지체(100); 상기 회동축에 회동가능하게 체결되고, 하부에 휠을 구비하는 휠몸체부(200); 상기 휠몸체부의 일단이 상하 이동가능하게 결합되는 수직방향 샤프트(310)를 구비하고, 상기 차체하부에 결합되는 제2지지체(300);를 포함하고, 상기 제2지지체(300)는, 상기 샤프트의 외주에 체결되는 스프링(S); 상기 스프링의 상하 위치에서 상기 샤프트에 체결되는 너트(320)와 스프링 안착부재(330); 상기 스프링 안착부재를 아래쪽에서 지지하는 가이드롤러(340); 상기 스프링 안착부재의 하단면에 형성되어 상기 가이드롤러가 안착되는 롤러홈(334);을 구비하고, 상기 휠몸체부가 상기 회동축을 기준으로 회동하면 상기 휠몸체부의 일단은 상기 가이드롤러와 접하면서 상기 스프링은 스프링의 길이방향으로 힘을 받는 것을 특징으로 한다.
