任一所述第一纵杆310远离另一所述第一纵杆310的一侧设置有第三纵杆330，所述第三纵杆330与所述第一纵杆310平行。
设置第三纵杆330与第一纵杆310平行，以使第一纵杆310和第三纵杆330形成一更大的支撑面，进而增大后桥段车架300与其他部件的接触面积，以提高其承重性能。
进一步地，所述第二纵杆320远离所述第一纵杆310的一侧还固接有两个板簧安装板360，两个所述板簧安装板360之间具有用于容纳后桥的空间。
具体地，本实施将板簧安装板360设置在第二纵杆320的下方一起承重受力，板簧安装板360在起到安装板簧作用的同时，还可与第二纵杆320/第一纵杆310一并受力，进一步提高整个后桥段车架300的承重性能。
进一步地，还设有多个斜支撑杆370，所述斜支撑杆370的一端与所述板簧安装板360固接，所述斜支撑杆370的另一端与所述第二纵杆320固接。
设置斜支撑杆370，提高板簧安装板360与第二纵杆320之间的连接强度，进而提高后桥段车架300的抗弯曲性能。
进一步地，还包括，尾段车架400，其与所述后桥段车架300远离所述中段车架200的一端连接。
需要说明，本发明实施例中所有方向性指示(诸如上、下、左、右、前、 后……)仅用于解释在某一特定姿态(如附图所示)下各部件之间的相对位置关系、运动情况等，如果该特定姿态发生改变时，则该方向性指示也相应地随之改变。
另外，在本发明中如涉及“第一”、“第二”、“一”等的描述仅用于描述目的，而不能理解为指示或暗示其相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。在本发明的描述中，“多个”的含义是至少两个，例如两个，三个等，除非另有明确具体的限定。
在本发明中，除非另有明确的规定和限定，术语“连接”、“固定”等应做广义理解，例如，“固定”可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系，除非另有明确的限定。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本发明中的具体含义。
另外，本发明各个实施例之间的技术方案可以相互结合，但是必须是以本领域普通技术人员能够实现为基础，当技术方案的结合出现相互矛盾或无法实现时应当认为这种技术方案的结合不存在，也不在本发明要求的保护范围之内。
