The invention relates to the technical field of commercial vehicle chassis, in particular to a heavy commercial vehicle front overhang foundation assembly which comprises a frame, a left bearing frame and a right bearing frame are fixedly mounted on the two sides of the front end of the frame respectively, bent connecting parts are arranged at the rear ends of the left bearing frame and the right bearing frame, and a front bent beam is fixedly mounted between the two bent connecting parts. A front traction beam is installed between the left bearing frame and the right bearing frame in a fastening mode, a hook pin shaft is installed on the front traction beam, positioning supports are fixedly connected to the bottoms of the front ends of the left bearing frame and the right bearing frame, a protection plate is connected between the two positioning supports in a fastening mode, and the rear side of the protection plate is connected with a front bent beam in a fastening mode. And protective beams are fixedly mounted at the front ends of the two positioning brackets. The torsion-resistant box body structure is arranged in the front overhang foundation assembly, the stability of the front overhang foundation assembly can be enhanced through the structure, the number of installation parts is reduced, the assembly technological process is simplified, meanwhile, installation errors are reduced, the development period is greatly shortened, and the development and production cost is controlled.

    本发明为一种重型商用车前悬基础总成,涉及商用车底盘技术领域,包括车架,车架的前端两侧分别固定安装有左侧承载架、右侧承载架,左、右侧承载架的后端设有弯接部,两个弯接部之间固定安装有前弯梁,左侧承载架与右侧承载架之间紧固安装有前牵引梁,前牵引梁上安装有钩销轴,左、右侧承载架的前端底部均固定连接有定位支架,两个定位支架之间紧固连接有防护板,防护板的后侧与前弯梁紧固相连,两个定位支架的前端固定安装有防护梁。本发明中设置有抗扭箱体结构,该结构可增强前悬基础总成的稳定性,并缩减安装零件的数量,简化装配工艺流程,同时降低安装误差,大幅度缩短开发周期,控制开发及生产成本。
