The invention relates to the technical field of suspensions, and particularly relates to a semitrailer air suspension which comprises a shell, an air bag, a guide rod, an impurity removing mechanism and a lubricating mechanism. The air bag is fixed at a top end of a shell; the guide rod is connected with the shell and an inner portion of the air bag in a sliding manner; the impurity removing mechanism is fixed to the bottom end of the shell and comprises a scraping ring, fixing blocks and a fixing sleeve, the fixing sleeve is installed at the bottom end of the shell, the hemispherical fixing blocks are symmetrically installed on the inner side wall of the fixing sleeve, and the top ends of the fixing blocks are fixedly connected with the scraping ring and slidably connected with the innerside wall of the guide rod; and the lubricating mechanism is installed in the fixing sleeve, and the inner portion of the fixing sleeve is connected with the guide rod in a sliding mode. According tothe semitrailer air suspension, dust is prevented from accumulating at a joint of the air bag suspension and the guide rod, and the guide rod can move conveniently.
