Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] In order to improve the reliability of the crossbeam connection, ensure that the crossbeam can provide sufficient support rigidity to the vehicle frame after the bolts are tightened, and avoid the risk of cracking caused by the stress concentration of the stamped sheet metal crossbeam due to local connection points, the integrally formed light weight of the present invention The quantitative casting beam assembly provides a new beam structure, which reduces the weight of the beam assembly, improves the torsion resistance of the frame, improves the fuel economy of the product, and reduces the manufacturing cost of the vehicle; in addition, the beam assembly is cast in one piece, It can reduce the risk of cracking of the weak link and improve the torsional capacity of the beam assembly.

Abstract

The invention discloses an integrally-formed lightweight cast cross beam assembly comprising a cross beam part, a longitudinal beam connecting end panel and a balanced suspension connecting bottom panel that are integrally formed through a casting process. The cross beam part is transversely arranged in a length direction, the longitudinal beam connecting end panel is formed on the end faces of the two transverse sides of the cross beam part, and the balanced suspension connecting bottom panel is formed below the bottom face of the cross beam part. Compared with a stamped metal plate cross beam, the integrally-formed lightweight cast cross beam assembly is lighter and more convenient, and the fuel economy of a vehicle can be better improved; compared with a stamped metal plate cross beam,the stress is more uniform, and the torsion resistance is higher; the integrated and light-weight design is adopted, the longitudinal beam connecting end panel and the balanced suspension connecting bottom panel are integrated on the transverse beam part, so that mounting supports of a front-end mounting system are reduced, the self weight of the frame can be reduced, and the design, manufacturingand management cost is also reduced.

Description

technical field [0001] The invention relates to the technical field of chassis components, in particular to an integrally formed lightweight cast beam assembly. Background technique [0002] The country has increasingly strict requirements on the curb quality of heavy-duty vehicles, and the beam needs to bear the torsional and bending stress from the frame, and its structural stability is very important for the structural stability of the vehicle. In order to meet the requirements of strength and rigidity, most of the beams used by heavy vehicles currently use stamped beams, and the beam assembly is made of stamping and tailor welding. [0003] The existing stamping beam has many parts, heavy weight, high manufacturing cost, and local riveting and bolt connection parts are likely to cause stress concentration. In addition, the overall torsional performance of the existing stamped sheet metal beam is relatively low. Contents of the invention [0004] The object of the pre...
