Abstract

The invention discloses a beam and longitudinal beam connecting assembly which comprises a beam, a longitudinal beam and a connecting piece for connecting the beam and the longitudinal beam. The corresponding positions on two opposite arms of the beam are provided with abutting openings; the connecting piece is a hollow blocky body; the middle parts of two side walls of the connecting piece are provided with connecting openings; the abutting openings on the beams correspond to the connecting openings of the connecting piece on the aspects of position, shape and size; the positions of the connecting openings on the side walls of the connecting piece are provided with outward turnover walls; the beam is connected with the connecting piece; the longitudinal beam is connected with the connecting piece; the connecting piece is embedded into the abutting openings of the beam; the longitudinal beam is embedded into the connecting openings of the connecting piece. The beam and longitudinal beam connecting assembly disclosed by the invention has a simple structure and solves the problem of difficulty in forming a U-shaped flanging of the beam; development of a die is simplified; quality of the beam and the longitudinal beam is controlled; the phenomena of wrinkling and cracking of a metal plate of a part are eliminated; local strength of a vehicle body and riding safety are improved.

Description

technical field [0001] The invention relates to a connecting assembly, in particular to a connecting assembly of a transverse beam of a vehicle body. Background technique [0002] At present, in the body manufacturing process, the beam and the longitudinal beam are directly overlapped together, the U-shaped overlap structure is not easy to form, and the mold development process is difficult; there are sheet metal wrinkling and cracking at the transition of rounded corners in the forming of parts; As a result, the parts crack during the driving process of the vehicle, which affects the structural strength of the vehicle and the safety of the vehicle. Contents of the invention [0003] The present invention is completed in order to solve the deficiencies in the prior art. The purpose of the present invention is to provide a simple structure, which solves the difficult problem of forming the U-shaped flange of the beam, simplifies the development of the mold, and controls the...
