Abstract

The invention relates to an automobile longitudinal beam structure which comprises a floor front longitudinal beam assembly, a floor middle longitudinal beam, a floor rear longitudinal beam, a rear bearing assembly and a safety belt lock catch mounting plate. The floor front longitudinal beam assembly, the floor middle longitudinal beam, the floor rear longitudinal beam and the rear baring assembly are sequentially connected. The requirement on the structural strength of the automobile longitudinal beam structure can be met, stamping feasibility of stamping parts is met, and weight of an automobile can be reduced; the floor longitudinal beam assembly can meet the requirement of crash test of a driving cab and the requirement of strength of fixed points of a safety belt.

Description

technical field [0001] The invention belongs to the field of automobile bodies, in particular to a longitudinal beam structure of a truck body. Background technique [0002] The current truck body, the longitudinal beam structure is a segmented structure, which is mainly composed of the floor front longitudinal beam, the floor rear longitudinal beam and the rear support, and bears the weight of the cab. [0003] The longitudinal beam structure of the truck body, the front longitudinal beam of the floor is arranged according to the engine space, the direction of width and height is large, and the stamping and forming is difficult. The rear support is a stamping part, which bears the weight of the cab. [0004] The front longitudinal beam of the floor is an ordinary plate, which is long and difficult to punch, and the material utilization rate is low; the rear support is a stamped part, which is difficult to stamp and form in a single piece, and product defects are prone to oc...
