Problems solved by technology

The chassis of the whole vehicle includes leaf spring rings, cab rear mounts, front spring rear bracket beams and suspension beams, and the leaf spring rings, cab rear mounts, front spring rear bracket beams and suspension beams are respectively connected to the vehicle frame and They are all concentrated in the middle and front end of the vehicle, which makes the layout space of the vehicle very limited and brings great trouble to the layout of the vehicle.
In addition, the crossbeam of the front spring and rear bracket mostly adopts sheet metal stamping structure. Due to the influence of the position of the gearbox, the shape of the crossbeam of the front spring and rear bracket is mostly complicated, resulting in high cost of large stamping dies and low torsional stiffness of the front spring and rear bracket beam.
At the same time, due to the production size error of the complex sheet metal structure, it is difficult to guarantee the accuracy of the outer width of the frame at the front end

Abstract

The invention relates to the technical field of automobile parts, and particularly discloses a cross beam assembly which comprises: a suspended cross beam; a front spring rear support cross beam assembly which is formed through integral casting, wherein the front spring rear support cross beam assembly comprises a front spring rear support cross beam, the front spring rear support cross beam comprises a bottom plate and side plates, and the two opposite ends of the bottom plate are connected with the side plates. frame fixing parts, wherein the frame fixing parts are used for being connected with a frame, and the two side plates are connected with the frame fixing parts; a cab rear suspension support, wherein the cab rear suspension support is used for being connected with a cab rear suspension, and the two frame fixing parts are both connected with the cab rear suspension support; suspension cross beam supports which are used for being connected with a suspension cross beam, wherein the two cab rear suspension supports are both connected with the suspension cross beam supports, and the suspension cross beam, the frame fixing parts and the front spring rear support cross beam forman annular structure; plate spring hanging ring supports which are used for being connected with a plate spring hanging ring, wherein the two side plates are provided with the plate spring hanging ring supports. The cross beam assembly is large in torsional rigidity, high in outer width precision and low in production cost, and the layout of the chassis is optimized.

Description

technical field [0001] The invention relates to the technical field of automobile parts, in particular to a beam assembly. Background technique [0002] With the development of commercial vehicle technology, the requirements for lightweight and integrated vehicle chassis are getting higher and higher. The chassis of the whole vehicle includes leaf spring rings, cab rear mounts, front spring rear bracket beams and suspension beams, and the leaf spring rings, cab rear mounts, front spring rear bracket beams and suspension beams are respectively connected to the vehicle frame and They are all concentrated in the middle and front end of the vehicle, which makes the layout space of the vehicle very limited and brings great trouble to the layout of the vehicle. In addition, the front spring and rear support beams mostly adopt sheet metal stamping structure. Due to the influence of the position of the gearbox, the shape of the front spring and rear support beams is mostly complica...
