Third cross beam assembly of frame and frame

Abstract

The invention relates to a third cross beam assembly of a frame and the frame. The third cross beam assembly of the frame comprises a cross beam upper piece, wherein the cross beam upper piece is provided with a raised reinforcing rib; the reinforcing rib is provided with a top wall and a side wall; a mounting seat for mounting an engine suspension is formed; the top wall is provided with top connecting hole used for fixing a bottom plate of the engine suspension; a side wall reinforcing lining plate is attached to the inner side and / or the outer side of the side wall; side connecting holes for fixing a side plate at the bottom of the engine suspension is formed in the side wall; side through holes corresponding to the side connecting holes are formed in the side wall reinforcing lining plate; and the reinforcing rib is connected with the cross beam upper piece in a tailor-welded mode. Through the design of the side wall reinforcing lining plates, the overall strength of the third cross beam assembly can be guaranteed while the installation requirement of a special engine suspension with side plates at the bottom is met. The invention further comprises a frame applying the third cross beam assembly.

Description

technical field [0001] The invention belongs to the field of auto parts, in particular to a third beam assembly of a vehicle frame and a vehicle frame. Background technique [0002] Among the many beams of the frame, the third beam assembly is connected with the longitudinal beam on the one hand, which can ensure the torsional rigidity of the frame and bear the longitudinal torsional load; on the other hand, it can also support some parts of the car, such as the engine, transmission However, for some engine mounts with special structures, such as engine mounts with side panels at the bottom, this special engine mount often has installation requirements on the two sides of the bottom of the third beam. Traditional The third beam structure of the frame cannot meet its installation requirements. [0003] The Chinese utility model patent document with the authorized announcement number CN204236561U discloses a third beam assembly for automobiles, including a third beam upper pa...

Problems solved by technology

[0004] It is not difficult to find that when the third beam assembly mentioned in the above-mentioned patent document is installed with an engine mount with special installation requirements on the side, if holes are opened on the side of the rib of the third beam assembly for special engine mount For the installation of the bottom side plate, its overall strength cannot meet the requirements due to the stamping characteristics of the third beam assembly; if the side plate at the bottom of the special engine mount is welded to the side of the top plate of the third beam assembly , because the welding space is too small, it is easy to cause the welding to be weak, and it is easy to cause the failure of the corresponding vehicle during the application process.
