连接筒15的第一端与左内筒体3相连接，连接筒15的第二端与右内筒体7相连接。
例如，连接筒15的两端分别与左内筒体3和右内筒体7焊接连接。如此设置，采用连接筒15分别与左内筒体3和右内筒体7焊接，能够降低加 工成本，并且使得后尾座总成便于加工。
本申请实施例中还提供一种车架。
具体来说，车架包括纵梁和如上所述的后尾座总成。
其中，纵梁的数量设置为两个，两个纵梁分别与左尾座和右尾座相连接。
需要说明的是，车架包含了后尾座总成也就包含了后尾座总成的所有优点，此处不再赘述。
可选地，两个纵梁分别设置为左纵梁和右纵梁。
其中，左纵梁与左尾座相连接，右纵梁与右尾座相连接。并且，左内腹板4和左外腹板2中的至少一者与左纵梁焊接连接，右内腹板8和右外腹板6中的至少一者与右纵梁焊接连接。
本申请实施例中还提供一种作业机械。
具体来说，作业机械包括如上所述的车架。
需要说明的是，作业机械包含了车架同时也就包含了如上所述的后尾座总成，因而也就包含了后尾座总成的所有优点，此处不再赘述。
同时需要说明的是，本文所述的作业机械包括但不限于自卸车。
最后应说明的是：以上实施例仅用以说明本申请的技术方案，而非对其限制；尽管参照前述实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的精神和范围。
