The invention discloses a coating-free heavy truck cab body assembly, which belongs to the technical field of automobile accessories and comprises a framework assembly made of aluminum alloy, and a skin component is arranged outside the framework assembly. The framework assembly comprises a front wall assembly, a floor assembly, a rear wall framework assembly, an air window framework assembly, a left side wall framework assembly, a right side wall framework assembly and a top cover framework assembly. The whole top cover framework assembly is of a criss-cross latticed structure, an L-shaped notch is formed in the end of the top cover framework assembly, and the L-shaped notch abuts against the inner side of the air window framework assembly, the inner side of the left side wall framework assembly and the inner side of the right side wall framework assembly respectively. The framework assembly made of aluminum alloy has the advantages of being light in weight, low in manufacturing cost, high in corrosion resistance and easy to machine, the stress capacity is optimized through the latticed structure of the top cover framework assembly, the structural stability of the whole framework assembly is improved through matching of the L-shaped notches and the inner sides of peripheral components, and the service life of the framework assembly is prolonged. And the risk that the top cover framework assembly and peripheral parts are broken due to external force collision is effectively reduced.
本发明公开一种免涂装重卡驾驶室本体总成,属于汽车配件技术领域,包括铝合金材质的骨架总成,骨架总成的外部设有蒙皮组件,骨架总成包括前围总成、地板总成、后围骨架总成、风窗骨架总成、左侧围骨架总成、右侧围骨架总成和顶盖骨架总成;顶盖骨架总成整体呈纵横交错的网格状结构,顶盖骨架总成的端部设有L型豁口,该L型豁口分别与风窗骨架总成、左侧围骨架总成及右侧围骨架总成的内侧相抵接。铝合金材质的骨架总成具有轻量化、造价低、耐腐蚀性能强和易加工的优点,顶盖骨架总成的网格状结构优化了受力能力,通过L型豁口与周边部件的内侧配合,提升了整个骨架总成的结构稳定性,有效降低受外力碰撞发生顶盖骨架总成与周边部件断裂的风险。
