The invention relates to the technical field of vehicle body frameworks, in particular to a heavy truck frame. A rear beam of the frame comprises a first cross beam and a second cross beam which are horizontally arranged front and back, a convex rib is arranged on the side, where the second cross beam is located, of the first cross beam, and a groove matched with the convex rib in an aligned modeis formed in the second cross beam. According to the heavy truck frame, the anti-collision and anti-deformation capacity of the rear beam of the frame is improved, a welding process is canceled, the maintenance cost is reduced while the structural safety is guaranteed, the problem that a welding structure of a traditional frame structure is prone to losing efficacy is solved, and the integrity andsafety of the frame are guaranteed.

    本发明涉及车体架构技术领域,尤其涉及一种重卡汽车车架,所述车架的后梁包括呈水平前后设置的第一横梁和第二横梁,所述第一横梁向第二横梁所在一侧设有凸筋,所述第二横梁上设有与凸筋对位配合的凹槽。本发明提供的重卡汽车车架提高了车架后梁的防撞抗变形能力,取消了焊接工艺,在保证结构安全的同时,降低了维护成本,解决了传统车架结构存在的焊接结构易失效的问题,保证了车架的完整度和安全性。
