The invention belongs to the technical field of commercial vehicle chassis and discloses an integrated rear cross beam assembly which is of an integrated structure. The integrated rear cross beam assembly comprises double rear cross beams, a first rear cross beam and a second rear cross beam, wherein the first rear cross beam and the second rear cross beam are parallel to each other and arranged at intervals, and the first rear cross beam is located at the rear end relative to the second rear cross beam; end parts of the first rear cross beam and the second rear cross beam are detachably connected with the frame longitudinal beam through cross beam connecting parts; the rear lower protection device is arranged on the first rear cross beam and is positioned at the rear lower part of the first rear cross beam; the rear traction device is arranged on the first rear cross beam and located right behind the first rear cross beam; the rear lower protection and traction functions are integrated on the rear cross beam, and the integration degree is high; integral structure forming is adopted, so that parts and connecting pieces of the whole vehicle are reduced, and the total weight of the rear cross beam assembly is reduced; the rear lower protection device and the rear traction device are arranged on the rear lower portion and the right rear portion of the first rear cross beam correspondingly and are optimized and reasonable in position layout.

    本发明属于商用车底盘技术领域,公开了一种集成化后横梁总成,为一体式结构,包括双后横梁,包括第一后横梁和第二后横梁,第一后横梁和第二后横梁相互平行且间隔设置,第一后横梁相对于第二后横梁处于后端,第一后横梁和第二后横梁的端部通过横梁连接部与车架纵梁可拆卸式连接;后下部防护装置,设于第一后横梁上且位于第一后横梁的后下部;后牵引装置设于第一后横梁上且位于第一后横梁的正后方。本发明将后下部防护和牵引功能集成在后横梁,集成程度高;采用一体结构成型,减少整车零部件及连接件,减轻后横梁总成的总体重量;后下部防护装置和后牵引装置分别设于第一后横梁的后下部和正后部,二者位置布局优化合理。
