Abstract

Provided is an integrated balance suspension cross beam assembly. A cross beam body in the integrated balance suspension cross beam assembly has a hollow sealed cylindrical structure. An air inlet andoutlet, and a water drain valve are arranged at the top and bottom of the middle section of the cross beam body respectively. Both ends of the cross beam body are connected with thrust rod connectingportions, large bracket connecting portions and longitudinal beam connecting portions. The cross beam body may be left, middle and right cylindrical portions which are sequentially connected. The longitudinal beam connecting portions include connecting bottom plates, and longitudinal beam connecting holes and bottom plate inner chambers arranged above the connecting bottom plates. The thrust rodconnecting portions comprise front and rear thrust rod connecting branch portions which are symmetrically arranged front and back with a center axis of the cross beam body as a symmetry line. The large bracket connecting portions comprise bracket bottom plates, bracket bottom holes, and front and rear support plates. This design has uniform stress distribution under torsional conditions and can increase the torsional performance of the cross beam. The integrated balance suspension cross beam assembly has the function of acting as an air reservoir, the manufacturing and assembly efficiency canbe improved, and the overall weight is reduced so as to be conducive to the modular layout of chassis.

Description

technical field [0001] The invention relates to a balance suspension crossbeam assembly, which belongs to the field of the automobile industry, in particular to an integrated balance suspension crossbeam assembly, which is specifically suitable for increasing the torsional performance of the crossbeam and also has the function of an air storage tank.
