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 specifically discloses a beam assembly. The beam assembly includes: a suspension beam; a front spring and a rear support beam assembly are integrally formed by casting. The front spring and rear support beam assembly includes: a front spring The rear support beam, the front spring and the rear support beam include a bottom plate and a side plate, and the opposite ends of the bottom plate are connected with side plates; the frame fixing part is used for connecting with the frame, and the two side plates are connected with the frame fixing part ;The rear suspension bracket of the cab is used to connect the rear suspension of the cab, and the two frame fixing parts are connected with the rear suspension bracket of the cab; the suspension beam bracket is used to connect the suspension beam, the rear of the two cabs The suspension brackets are all connected with suspension beam brackets, the suspension beam, the frame fixing part and the front spring rear bracket beam form a ring structure; the leaf spring lifting ring bracket is used to connect the leaf spring lifting ring, and both side plates are provided with plates Spring Ring Bracket. The torsional rigidity of the beam assembly is high, the outer width is high precision, the production cost is low, 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...
