The invention relates to a top cover rear cross beam assembly. A top cover rear cross beam comprises a first supporting frame, a second supporting frame, a first connector, a second connector and a rear cross beam body, wherein the first connector is fixed to the first supporting frame and assembled to form a cavity, an anti-torque supporting piece is assembled in the cavity, the second connectoris fixed to the second supporting frame and assembled to form a cavity, an anti-torque supporting piece is assembled in the cavity, one end of the rear cross beam body is fixedly connected with the first connector, the other end of the rear cross beam body is fixedly connected with the second connector, the rear cross beam body is of a hollow structure, the hollow structure is communicated with the cavities in the first supporting frame and the second supporting frame, so a U-shaped torsion-resistant cavity is formed. The top cover rear cross beam assembly is advantaged in that local rigidityand modality of a tail door frame are improved, overall rigidity of a vehicle body is improved, torsional deformation of the vehicle body on severe pavements is reduced, and abnormal sound and resonance are reduced.
本发明涉及一种顶盖后横梁总成,所述的顶盖后横梁包括第一支撑架、第二支撑架、第一连接头、第二连接头、后横梁本体;所述的第一连接头固定在第一支撑架上并装配形成空腔,该空腔中装配有抗扭支撑件;所述的第二连接头固定在第二支撑架上并装配形成空腔,该空腔中装配有抗扭支撑件;所述的后横梁本体一端与第一连接头固定连接;所述的后横梁本体另一端与第二连接头固定连接;所述的后横梁本体为中空结构,该中空结构与第一支撑架以及第二支撑架中的空腔相通,从而形成U形抗扭腔体。其优点表现在:提高尾门框局部刚度及模态,提升车身整体刚性,减轻恶劣路面下车身扭转变形,减少异响及共振。
