A wrecker subframe rail

Abstract

A kind of wrecker auxiliary frame longitudinal beam, including plate-like longitudinal beam main body, longitudinal beam main body is horizontally arranged, and one end edge is bent down first, forms first bending bending position, continue to bend down to the vertical direction of longitudinal beam main body, form second bending position, bend down again to form third bending position, finally bend down again to the vertical direction of longitudinal beam main body, form fourth bending position, plate-like longitudinal beam main body is bent down through multiple bending positions and forms two-stage three-dimensional stepped structure with.The wrecker auxiliary frame longitudinal beam of the utility model is the invisible ridge beam of special function for wrecker, with high-strength structure support dynamic load, through collapse design to resolve the impact of cargo gravity, and the impact brought by hydraulic system lifting, and optimize NVH performance, it is particularly outstanding in lightweight, multifunctional and safety, become the essential component of modern automobile, especially wrecker.
