The invention belongs to the technical field of vehicles, and discloses an independent suspension system and a commercial vehicle. An upper half auxiliary frame assembly of the independent suspension system is distributed above two main frame longitudinal beams, and the two ends of the upper half auxiliary frame assembly are fixedly connected with the two main frame longitudinal beams respectively. The lower half auxiliary frame assembly is distributed below the two main frame longitudinal beams, and the two ends of the lower half auxiliary frame assembly are fixedly connected with the two main frame longitudinal beams respectively. An upper cross arm of the suspension assembly and the shock absorber assembly are both rotationally connected with the upper half auxiliary frame assembly, the spring assembly is fixedly connected with the upper half auxiliary frame assembly, and a lower cross arm is rotationally connected with the lower half auxiliary frame assembly. A cage-shaped first containing space is formed among the upper half auxiliary frame assembly, the lower half auxiliary frame assembly and the two main frame longitudinal beams, and the first containing space is at least used for containing an engine and two steering assemblies. The structural strength of the main frame longitudinal beam and the auxiliary frame assembly can be improved, so that the commercial vehicle is good in use comfort, operation stability and safety, and the structure of the commercial vehicle is compact.

    本发明属于车辆技术领域,公开了独立悬架系统及商用车。该独立悬架系统的上半副车架总成分布于两个主车架纵梁的上方,上半副车架总成两端分别与两个主车架纵梁固定连接;下半副车架总成分布于两个主车架纵梁的下方,下半副车架总成的两端分别与两个主车架纵梁固定连接;悬架总成的上横臂和减振器总成均与上半副车架总成转动连接,弹簧总成与上半副车架总成固定连接,下横臂与下半副车架总成转动连接;上半副车架总成、下半副车架总成和两个主车架纵梁之间形成笼状的第一容置空间,第一容置空间至少用于容置发动机和两个转向总成。能提升主车架纵梁和副车架总成的结构强度,使得商用车的使用舒适性、操稳性和安全性好,且使得商用车的结构紧凑。
