The invention belongs to the technical field of vehicle equipment, and particularly relates to an automobile chassis. The automobile chassis comprises a chassis main beam, a chassis cross beam and a supporting cross beam, the number of the chassis main beams is two, the two chassis main beams are arranged in parallel, the cross section of each chassis main beam is in a U shape, and openings of the two chassis main beams are oppositely arranged. The number of the supporting cross beams is multiple, all the supporting cross beams are arranged between the two chassis main beams, the length direction of the supporting cross beams is perpendicular to the length direction of the chassis main beams, the chassis cross beams are arranged at the ends of the chassis main beams, and the two ends of each chassis cross beam are fixedly connected with the two chassis main beams respectively. The cross section of the chassis main beam in the automobile chassis is of the U-shaped structure, the bending moment capable of being borne by the chassis main beam is similar to the bending moment capable of being borne by a rectangular pipe, and the using amount of materials is smaller than that of the rectangular pipe, so that the using amount of the materials for manufacturing the chassis main beam is reduced, and the cost of the automobile chassis is effectively reduced.
本发明属于车辆设备技术领域,具体涉及一种汽车底盘;其包括底盘主梁、底盘横梁和支撑横梁;底盘主梁的数量为两个,两个底盘主梁平行设置,且底盘主梁的截面形状为“凵”字形,两个底盘主梁的开口相对设置;支撑横梁的数量为多个,所有的支撑横梁均设置在两个底盘主梁之间,且支撑横梁的长度方向与底盘主梁的长度方向垂直,底盘横梁设置在底盘主梁的端部,且底盘横梁的两端分别与两个底盘主梁连接固定。该汽车底盘中的底盘主梁的截面形状为“凵”字形结构,其所能承受的弯矩与矩形管所能承受的弯矩相近,且材料的使用量少于矩形管的材料的使用量,使得制作底盘主梁的材料的用量减少,从而有效的降低了汽车底盘的成本。
