The vehicle frame assembly comprises two vehicle frame longitudinal beams, the two vehicle frame longitudinal beams are distributed in the width direction of a vehicle body in a spaced mode, the tops of the two ends of each vehicle frame longitudinal beam are both arranged in a sunken mode, so that a first expanded area is formed at the top of one end of each vehicle frame longitudinal beam, and a second expanded area is formed at the top of the other end of each vehicle frame longitudinal beam; and the vehicle frame cross beam assembly is fixed between the two vehicle frame longitudinal beams. The tops of the two ends of the frame longitudinal beam are sunken, so that the top of one end of the frame longitudinal beam forms a first expanded area, the top of the other end of the frame longitudinal beam forms a second expanded area, and the first expanded area can meet the design requirements of low floor and flat floor of a cab, enlarge the internal space of the cab, improve the riding comfort of a driver and reduce the stepping height of the cab; the second expanded area can increase the volume of the container; a frame assembly is designed in different areas and is divided into a front area, a middle area and a rear area; the front and rear regions form a low-cross-section region, and the middle region forms a high-cross-section region.
本发明涉及一种车架总成及车辆,其包括:两个车架纵梁,两个所述车架纵梁沿车身宽度方向间隔分布,所述车架纵梁的两端顶部均凹陷设置,使所述车架纵梁的一端顶部形成第一扩大区域,其另一端顶部形成第二扩大区域;车架横梁总成,所述车架横梁总成固定于两个所述车架纵梁之间。通过车架纵梁的两端顶部均凹陷设置,使车架纵梁的一端顶部形成第一扩大区域,其另一端顶部形成第二扩大区域,第一扩大区域可满足驾驶室低地板平地板设计需求,加大驾驶室内部空间,提升驾驶员乘坐舒适度,可降低驾驶室踏步高度;第二扩大区域可增加货箱容积;将车架总成实现分区域设计,分为前、中、后三个区域;前、后区域形成低截面区域,中部区域形成高截面区。
