The invention relates to the field of vehicle manufacturing, in particular to an all-aluminum-alloy welding-free frame structure assembly which comprises a longitudinal beam and a cross beam assembly, the cross beam assembly comprises a first cross beam and a second cross beam, and the first cross beam comprises a first cross beam base body and a cross beam reinforcing part; the first cross beam base body is correspondingly locked with a high-load area on the longitudinal beam; the cross beam reinforcer is locked with the side face of the first cross beam base body and the longitudinal beam at the same time. The second cross beam comprises a second cross beam base body, and the second cross beam base body is locked with the low-load area on the longitudinal beam. Through the design of the first cross beam and the second cross beam, cross beam structures with different bearing capacities are specifically adopted on the longitudinal beams, the bearing capacity of the frame is improved while the structure is light, and the service life of the frame is prolonged; the connecting strength of the cross beams and the longitudinal beams is improved through multi-point connection of the cross beam reinforcers of the first cross beams designed in the high-load area.
本发明涉及车辆制造领域领域,尤其涉及一种全铝合金无焊接车架结构总成,包括纵梁和横梁组件,所述横梁组件包括第一横梁和第二横梁,所述第一横梁包括第一横梁基体和横梁加强件,所述第一横梁基体与纵梁上的高载荷区域对应锁付;所述横梁加强件同时与第一横梁基体的侧面、纵梁锁付;所述第二横梁包括第二横梁基体,所述第二横梁基体与纵梁上的低载荷区域锁付。通过第一横梁和第二横梁的设计,针对性地在纵梁上采用承载能力不同的横梁结构,结构轻量化的同时提高车架的承载能力,提高车架使用寿命;通过设计在高载荷区域的第一横梁的横梁加强件,由横梁加强件的多点连接来提高横梁与纵梁的连接强度。
