Abstract

본 발명은 무인운반차의 현가장치에 관한 것으로, 무인운반차 본체(1)의 상부프헤임(4)과 하부프헤임(5)에 고정설치된 브라켓트(6)에 상하방향으로 다수개의 가이드바(7)가 설치되어 있고, 상기 가이드바(7)의 소정 위치에는 상부 스프링지지판(8a)이 고정설치되어 있으며, 상기 상부 스프링지지판(8a)의 하부에는 상기 가이드바(7)에 의해 안내되는 하부스프링지지판(8b)가 설치되어 있는 한편, 상기 상부 스프링지지판(8a)과 상부 스프링지지판(8b)사이에는 스프링(10)이 부설되어 있고, 상기 하부 스프링지지판(8b)에는 구동바퀴(2)가 설치되므로써, 구동바퀴(2)의 상,하 수직운동을 안정되게 하여 굽힘응력에 의한 현가장치(3)의 피로파괴를 방지하여 현가장치(3)의 수명을 증가시킬 수 있도록 함과 더불어 무인운반차의 정지정밀도와 위치정밀도를 높일 수 있도록 한 것이다.The present invention relates to a suspension device for an unmanned vehicle, a plurality of guide bars in the vertical direction on the bracket (6) fixed to the upper frame (4) and the lower frame (5) of the unmanned vehicle body (1) ( 7) is installed, the upper spring support plate (8a) is fixed to the predetermined position of the guide bar (7), the lower portion of the upper spring support plate (8a) guided by the guide bar (7) A spring support plate 8b is provided, while a spring 10 is provided between the upper spring support plate 8a and the upper spring support plate 8b, and a driving wheel 2 is provided on the lower spring support plate 8b. Since it is installed, the vertical movement of the driving wheel 2 is stabilized to prevent fatigue destruction of the suspension device 3 due to bending stress, thereby increasing the service life of the suspension device 3 and unmanned transportation. It is possible to increase the stopping accuracy and position accuracy of the car. One will.
