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.

    本发明涉及悬架技术领域,具体的说是一种半挂车空气悬架,包括外壳,气囊,导杆,除杂机构和润滑机构,所述气囊固定于所述外壳的顶端;所述导杆滑动连接所述外壳和所述气囊的内部;所述除杂机构固定于所述外壳的底端,所述除杂机构包括刮环、固定块和固定套,所述外壳的底端安装所述固定套,所述固定套的内侧壁对称安装半球形的所述固定块,所述固定块的顶端固定连接所述刮环滑动连接所述导杆的内侧壁;所述润滑机构安装于所述固定套的内部,且所述固定套的内部滑动连接所述导杆。本发明提供的半挂车空气悬架避免灰尘堆积在气囊悬架与导杆的连接处,方便导杆运动。
