The invention provides a passenger car chassis, which belongs to the technical field of vehicles and comprises a frame, a rear axle framework is fixedly arranged on the frame and comprises a rear axle longitudinal beam and a rear axle cross beam perpendicular to the rear axle longitudinal beam, a thrust rod seat is fixedly arranged on the rear axle cross beam, and a longitudinal beam inclined strut is fixedly arranged between the rear axle longitudinal beam and the rear axle cross beam. In the vertical direction, the connecting position between the longitudinal beam inclined strut and the rear axle cross beam and the connecting position between the thrust rod base and the rear axle cross beam are arranged in a staggered mode. The mounting structure has the advantages that in order to ensure the mounting space of the thrust rod seat, the connecting position of the longitudinal beam inclined strut mounted on the rear axle longitudinal beam is adjusted, so that the connecting positions of the thrust rod seat and the longitudinal beam inclined strut on the rear axle longitudinal beam are inconsistent in the vertical direction, and the influence of the mounting position of the longitudinal beam inclined strut on the mounting and fixing of the thrust rod seat can be effectively avoided; enough welding space is reserved, so that the thrust rod seat can be independently welded and fixed on the rear axle cross beam, and the connection stability of the thrust rod seat is improved.

    本发明提供了一种客车底盘,属于车辆技术领域,包括车架,车架上固定设置有后桥骨架,后桥骨架包括后桥纵梁,以及与后桥纵梁垂直设置的后桥横梁,后桥横梁上固定设置有推力杆座,且后桥纵梁与后桥横梁之间固定设置有纵梁斜撑,在竖直方向上,纵梁斜撑与后桥横梁之间的连接位置和推力杆座与后桥横梁之间的连接位置错开设置;优点是为了保证推力杆座的安装空间,调整安装在后桥纵梁上的纵梁斜撑的连接位置,使的推力杆座与纵梁斜撑在后桥纵梁上的连接位置在竖直方向上不一致,可有效避免纵梁斜撑的安装位置对推力杆座的安装固定的影响,留有足够的焊接空间,使得推力杆座可独立焊接固定在后桥横梁上,增加推力杆座的连接稳固性。
