The invention discloses a connecting structure of a chassis axle and a frame, which is characterized in that a thrust rod of the axle is moved to the middle position of an axle housing, a thrust rod support is lifted, a hole is formed in the middle position of a lower bottom plate of the frame to avoid the thrust rod support, and the thrust rod on the axle is arranged in the frame; and an axle upper thrust rod support corresponding to the axle upper thrust rod is arranged in the frame. By changing the layout structure form of the axle and the frame, the box size of the frame is increased, the height of the whole machine is not increased, and the bearing bending resistance of the frame is improved by 40%.

    本发明公开了一种底盘车桥与车架的连接结构,将车桥的推力杆移动到车桥桥壳的中间位置,将推力杆支座抬高,车架在车架下底板中间位置开洞避开推力杆支座,将车桥上推力杆置于车架内,车架内设有与车桥上推力杆对应的车桥上推力杆支座。本发明通过改变车桥与车架的布局结构形式,实现车架箱型尺寸增大,不增加整机高度,车架承载抗弯能力提高40%。
