Beschreibung
Zusammenfassung:	An automobile front longitudinal beam structure with variable thickness is characterized by comprising a first equal-thickness segment, a first transition segment and a second equal-thickness segment, wherein the first equal-thickness segment, the first transition segment and the second equal-thickness segment are sequentially arranged from the front to the rear of a front longitudinal beam; the thickness of the fracture surface of the first equal-thickness segment is smaller than the thickness of the fracture surface of the second equal-thickness segment; the first transition segment is a thickening segment with the thickness of the fracture surface in continuous transition; the first equal-thickness segment, the first transition segment and the second equal-thickness segment are of an integrated structure and made of a steel plate with the thickness of the fracture surface in continuous transition at different portions. According to the automobile front longitudinal beam structure, due to the different-thic
