The invention discloses an all-aluminum passenger car top cross beam profile. The profile comprises a profile body, a cavity is defined by the profile body, a connecting plate is connected in the profile body in the vertical direction, and the cavity is divided into a first cavity and a second cavity through the connecting plate; the right side of the profile body is connected with a first L-shaped side plate, a second L-shaped side plate and a third straight side plate; the left side of the profile body is connected with a third L-shaped side plate, a fourth L-shaped side plate and a second straight side plate. Compared with an existing all-aluminum passenger car roof support, the multi-cavity section structure can obviously reduce the mass of the roof, the manufacturing cost of an all-aluminum passenger car is reduced, and the structural performance of the roof is guaranteed.
本发明公开了一种全铝客车顶横梁型材。本发明包括型材主体,型材主体,型材主体围成型腔,型材主体内上下方向连接有连接板,连接板将型腔分为型腔一和型腔二;所述型材主体右侧连接有L型侧板一、L型侧板二和直侧板三;所述型材主体左侧连接有L型侧板三、L型侧板四和直侧板二。本发明与现有的全铝客车顶棚支架相比,该多行腔断面结构可以明显降低顶棚质量,减少全铝客车的制造成本,同时保证顶棚结构性能。
