The invention discloses an ultrahigh-strength tubular front and rear lower protection device for a commercial vehicle. The device comprises a cross rod and a support assembly symmetrically arranged on the cross rod. The support assembly comprises a support pipe assembly connected to the cross rod and a mounting plate arranged on the support pipe assembly. According to the ultrahigh-strength tubular front and rear lower protection device for the commercial vehicle, the cross rod and the support pipe assembly are both of a thin-wall tubular structure, the tensile strength is larger than or equal to 1500 MPa through the hot roll bending technology, the structure is simple, universality is high, the manufacturing technology is simple, the process is short, the requirements of related laws and regulations can be met, light weight can be achieved, and the problems that in the prior art, a commercial vehicle front and back lower protection device is complex in structural design, large in size, low in strength and heavy in mass are solved.

    本发明公开了一种超高强管状商用车前后下防护装置,包括横杆以及对称设于所述横杆上的支架总成;所述支架总成包括连于所述横杆上的支架管组件以及设于所述支架管组件上的安装板。该超高强管状商用车前后下防护装置的横杆以及支架管组件均采用薄壁管状结构,并通过热辊弯工艺使其抗拉强度≥1500MPa,结构简单、通用性强,且制造工艺简单、流程短,既能满足相关法规要求又能实现轻量化,解决现有技术中商用车前后下防护装置结构设计繁杂、体积大、强度低以及质量重的难题。
