The invention discloses a rear-mounted bus chassis frame. The rear-mounted bus chassis frame is characterized in that a left longitudinal beam and a right longitudinal beam are in an integral structure formed by once stamping, the left longitudinal beam is in the Z-shaped structure in the longitudinal direction and the right longitudinal beam is in the 'n' font structure in the longitudinal direction, so that a connecting structure with the high front section of the left longitudinal beam and the low front section of the right longitudinal beam is formed; the first beam structure of the frame is in the Z-shaped one with the high left part and the low right part and connected with left and right longitudinal beams; the left longitudinal beam is up and down vertically arranged on a connecting bracket, the second beam of the frame is connected with the lower end of the connecting bracket, and the other end of the second beam is connected with the right longitudinal beam. The rear-mounted bus chassis frame is characterized in that bearing capacity of the integral longitudinal beam is much better than that of the sectioned overlapping joint longitudinal beam, the weight is also reduced by 15-20%, and the manufacturing cost of the frame is reduced. The seat of a driver is considered in the front structure and the front structure is arranged at the high position; foot steps in a front door are relatively low, the front wheel arch is considered in design, the height of the whole bus is reduced, the sectioned connection manner of front and middle sections can be broken, and a console in the driver side can be designed, and thus passengers can conveniently get on or off the bus.
