The invention provides a large-load undercarriage spring which comprises an outer barrel, an inner barrel, a spring and a spring body. The outer barrel is provided with a single-lug structure and a barrel-shaped structure. The plug cap is arranged at the end part of the cylindrical structure of the outer cylinder and is used for supporting the cylindrical structure of the outer cylinder; the piston rod is provided with a round rod structure and a single-lug structure, the round rod structure of the piston rod penetrates through the plug cap and partially extends into the cylindrical structure of the outer cylinder, and an end bolt is installed at the end of the round rod structure; the front supporting sleeve and the rear supporting sleeve are installed on the cylindrical structure inner round rod structure extending into the outer cylinder, the front supporting sleeve is in contact with the outer cylinder, and the rear supporting sleeve is in contact with the plug cap; the spring is arranged on the front supporting sleeve and the rear supporting sleeve in a sleeving mode and located in the cylindrical structure of the outer cylinder, the two ends of the spring make contact with the front supporting sleeve and the rear supporting sleeve respectively, and the spring is a compression spring. The undercarriage tension spring can solve the problems that a tension spring is insufficient in bearing capacity and poor in stability.
