The invention discloses a vehicle with a non-bearing type vehicle body, a frame girder and a preparation method of the frame girder, and the frame girder is applied to the vehicle with the non-bearing type vehicle body. Comprising a first beam body and a second beam body, the first beam body comprises an opening beam and a cover plate beam, the opening beam comprises a U-shaped beam section, the U-shaped beam section is provided with an inner cavity and a side opening, the side opening is communicated with the inner cavity, the second beam body is a rectangular beam, the second beam body comprises an embedded section, and the embedded section is connected with the cover plate beam. The embedded section is located in the inner cavity of the U-shaped beam section, the cover plate beam covers the side opening, the cover plate beam and the opening beam are welded and fixed, and the opening beam and the second beam body are welded and fixed. According to the frame girder, the sectional design is adopted, strength distribution can be conveniently conducted on the frame girder according to the bearing requirement of a vehicle, and the situation that the bearing capacity is excessive or insufficient can be avoided to a large extent.

    本发明公开一种采用非承载式车身的车辆、车架大梁及其制备方法,其中,该车架大梁应用于采用非承载式车身的车辆;包括第一梁体和第二梁体,所述第一梁体包括开口梁和盖板梁,所述开口梁包括U型梁段,所述U型梁段具有内腔和侧部开口,所述侧部开口和所述内腔相连通,所述第二梁体为矩形梁,所述第二梁体包括嵌装段,所述嵌装段位于所述U型梁段的所述内腔中,所述盖板梁覆盖于所述侧部开口,所述盖板梁和所述开口梁焊接固定,所述开口梁和所述第二梁体焊接固定。上述车架大梁采用分段式设计,可方便地根据车辆的承载要求对车架大梁进行强度分配,能够较大程度地避免出现承载能力过剩或者不足的情形。
