[0002] As people's living standards continue to improve, people's requirements for automobile transportation efficiency and various functions continue to increase. Large highway buses have the characteristics of large luggage compartment space and high passenger capacity, which can significantly improve bus transportation efficiency.

[0003] The structural scheme of middle axle drive and rear axle follower can effectively increase the passenger capacity of buses. The rear section of the existing follower axle suspension is mostly integral, and the thrust rod support of the suspension V-push is welded to the middle part below. This section is an integral structure. Limited by the strength of the suspension and the overall structure, the middle connection is mostly in an integral state, but it is not convenient for the installation of the intermediate drive shaft. At the same time, if the rear overhang of the whole vehicle is short and the powertrain is long, the powertrain components invade the follower axle area, which is not convenient for the installation of the powertrain and avoidance of the powertrain.
