The invention relates to the technical field of operation machinery, and provides a connecting structure of a frame and a front axle, a chassis and an operation machine.The connecting structure of the frame and the front axle comprises a mounting base, a mounting frame and a fastening assembly, the mounting base is formed on the front axle, and the central axis of the mounting base is consistent with the front-back direction of the front axle; the mounting frame is rotatably sleeved on the mounting seat, and the mounting frame coincides with the central axis of the mounting seat relative to the rotating axis of the mounting seat; and the mounting rack and the frame are fixedly connected together by the fastening assembly. Generally, the mounting base is formed at the position, used for being connected with the transmission shaft, of the front axle, the mounting base is large in rigidity and strength and not prone to deformation, in addition, during overhauling, the front axle and the frame can be separated only by disassembling the fastening assembly, operation is easy and convenient, and the maintenance cost is reduced. The problem that in the prior art, due to the fact that a pin shaft is used for hinging a front axle and a vehicle frame together, the pin shaft is prone to being damaged and cannot be disassembled when impacted is solved.

    本发明涉及作业机械技术领域,提供一种车架与前桥的连接结构、底盘及作业机械,其中,车架与前桥的连接结构包括安装座、安装架和紧固组件,安装座形成于前桥,安装座的中心轴线与前桥的前后方向一致;安装架可转动地套设于安装座,安装架相对于安装座的转动轴线与安装座的中心轴线重合;紧固组件将安装架与车架固定连接在一起。一般情况下,前桥上用于连接传动轴的位置处形成有上述安装座,安装座的刚度和强度较大,不易变形,而且,在检修时,仅需要将紧固组件拆下,即可将前桥与车架相分离,操作简单、方便,解决了现有技术中利用销轴将前桥与车架铰接在一起导致的在受到冲击时销轴容易受损而无法拆解的问题。
