The invention relates to a suspension structure of a lifting axle of a commercial vehicle. The suspension structure comprises a supporting bracket, a lifting air bag, a guide arm and a bearing air bag, the guide arm is connected with the axle; the front end of the guide arm is hinged with the supporting bracket; the lower end of the lifting airbag is connected with the supporting bracket, and theupper end of the lifting airbag is fixedly connected with the guide arm; and the lower end of the bearing airbag is connected with the tail end of the guide arm. According to the suspension structureof the lifting axle of the commercial vehicle, the upper end of the lifting air bag is directly connected with the guide arm, elements such as an upper swing arm of a lifting mechanism are omitted, and the problem that the mounting space size of the lifting air bag is narrow is solved. Acting force of the lifting air bag is directly transmitted to the guide arm, and abrasion of the guide arm and noise in lifting motion are avoided; the guide arm and the lifting air bag are integrated, influence of a transmission shaft can be effectively avoided, the lifting axle suspension structure can be arranged in front of a drive axle and is also suitable for being arranged behind the drive axle for use, and therefore the suspension universality is high.

    本发明涉及一种商用车提升桥悬架结构,包括:支承支架、提升气囊、导向臂及承载气囊。导向臂与车桥连接;导向臂的前端与支承支架铰接;提升气囊的下端与支承支架连接,提升气囊的上端与导向臂固定连接;承载气囊的下端与导向臂的末端连接。本发明提供的商用车提升桥悬架结构,将提升气囊上端直接与导向臂相连,省掉提升机构的上摆臂等元件,解决提升气囊安装空间尺寸狭小问题。提升气囊作用力直接传递到导向臂,避免导向臂的磨损与提升运动中的噪声;导向臂与提升气囊融为一体,可有效规避传动轴影响,该提升桥悬架结构既可以布置在驱动桥前面,又适宜布置在驱动桥后面使用,因此悬架通用性好。
