The steel-aluminum hybrid heavy truck body structure comprises a lower truck body assembly and a top cover assembly, the lower truck body assembly is connected with the top cover assembly through a connecting set, the lower truck body assembly is made of steel, and the top cover assembly is made of aluminum. The aluminum top cover assembly and the steel lower vehicle body assembly are adopted, the performance requirements of vehicle body safety, durability, NVH and the like are met, meanwhile, the double requirements of light weight and low cost are met, mass production can be achieved, and high practical significance is achieved; due to the fact that the density of the aluminum alloy is only 1/3 of that of steel, compared with a steel top cover assembly, the aluminum top cover assembly can properly increase the material thickness, and the strength and rigidity of the top cover assembly can be improved while the weight is reduced.
本申请涉及一种钢铝混合重卡车身结构及其汽车,其包括:下车身总成和顶盖总成,下车身总成通过连接组与顶盖总成连接,下车身总成为钢制,顶盖总成为铝制。本发明中,采用铝制顶盖总成和钢制下车身总成,在满足车身安全性、耐久性、NVH等性能要求的同时,又满足了轻量化和成本低的双需求,并且能够实现量产,有很高的实用意义;由于铝合金密度仅为钢材的1/3,相较于钢制顶盖总成,铝制顶盖总成可以适当提升其料厚,在轻量化的同时,可以提升顶盖总成的强度和刚性。
