The invention relates to the technical field of semitrailers, in particular to a semitrailer suspension device which comprises a suspension frame, an air bag is fixedly connected to the lower surface of the suspension frame, a supporting plate is fixedly connected to the bottom end of the air bag, an axle is fixedly connected to the lower surface of the supporting plate, two water storage cavities are formed in the suspension frame, and two containing grooves are formed in the inner walls of the water storage cavities. According to the steel plate spring cooling device, a first-stage branch pipe and a water outlet head are arranged to conduct water cooling on a steel plate spring located on the upper portion, and a second-stage branch pipe, a soft leather pipe and a supporting base are matched to be used for conducting water spraying cooling on a steel plate spring located on the lower portion; the spring is used for enabling the soft leather hose to shake up and down to spray water in a large range for cooling when the vehicle bumps up and down, so that the problems that an existing suspension device does not have a plate spring cooling function, heat generated by friction of the plate spring accelerates abrasion of the plate spring, and the service life of the vehicle is affected are solved.

    本发明涉及半挂车技术领域,具体是一种半挂车悬挂装置,包括悬挂架,悬挂架的下表面固定连接有气囊,气囊的底端固定连接有托板,托板的下表面固定连接有车桥,悬挂架的内部开设有两个储水腔,储水腔的内壁开设有两个放置槽,放置槽的内壁固定连接有总水管,本发明中,通过设置一级支管和出水头给处于上方的钢板弹簧水冷降温,二级支管、软皮管和支撑座相配合用于给处于下方的钢板弹簧喷水降温,弹簧用于车辆上下颠簸时使得软皮管上下抖动以大范围地喷洒水进行冷却,从而解决了现有的悬挂装置不具备板簧冷却功能,板簧摩擦产生的热量会加速板簧的磨损,影响车辆使用寿命的问题。
