Longitudinal beam assembly of vehicle, front plate spring brackets and wagon

Abstract

The invention discloses a longitudinal beam assembly of a vehicle, front plate spring brackets and a wagon. The longitudinal beam assembly of the vehicle comprises two separated longitudinal beams, abent pipe crossbeam and the two separated front plate spring brackets. The bent pipe crossbeam is arranged between the longitudinal beams. The bent pipe crossbeam is suitable for being arranged on thefront side of a vehicle engine. Each front plate spring bracket comprises a front plate spring mounting plate and a longitudinal beam mounting plate. The front plate spring mounting plates are used for being connected with front plate springs and further being connected with one end of the bent pipe crossbeam. The longitudinal beam mounting plates are perpendicularly arranged on the front plate spring mounting plates and fixed to the outer end faces of the longitudinal beams. Thus, through matching of the two separated longitudinal beams, the bent pipe crossbeam and the two separated front plate spring brackets, the space on the inner sides of the longitudinal beams can be saved, the interference problem of the bent pipe crossbeam and a water tank fan protection cover can also be prevented, moreover, the influence of the bent pipe crossbeam and a steering engine bracket on space arrangement can also be avoided, and arrangement of pipelines on the inner sides of the longitudinal beamscan further be facilitated.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle longitudinal beam assembly, a front leaf spring bracket and a truck. Background technique [0002] The frame of a freight vehicle is generally designed with a bent tube beam at the front of the engine, which is used to strengthen the frame here, such as Figure 1-Figure 4 As shown, the curved pipe beam is generally connected to the inner side of the left and right longitudinal beams of the frame through two connecting plates. The disadvantages of this structure are: 1. The layout space of the connecting plate is affected by the steering gear bracket and the front leaf spring bracket. 2. The curved pipe The gap between the beam and the windshield of the water tank is too close to easily cause dynamic interference. 3. The pipeline layout inside the left and right longitudinal beams is greatly affected by the elbow beam. [0003] In related technologies, there are mainly ...

Problems solved by technology

[0002] The frame of a freight vehicle is generally designed with a bent tube beam at the front of the engine, which is used to strengthen the frame here, such as Figure 1-Figure 4 As shown, the curved pipe beam is generally connected to the inner side of the left and right longitudinal beams of the frame through two connecting plates. The disadvantages of this structure are: 1. The layout space of the connecting plate is affected by the steering gear bracket and the front leaf spring bracket. 2. The curved pipe The gap between the beam and the windshield of the water tank is too close to easily cause dynamic interference. 3. The pipeline layout inside the left and right longitudinal beams is greatly affected by the elbow beam

[0004] Option 1: If figure 1 and figure 2 As shown, the curved pipe beam is formed by bending a steel pipe, and a connecting plate is welded at each end. The connecting plate is placed on the inner side of the longitudinal beam and connected with the left and right longitudinal beams by bolts. The steering gear bracket is fixed to the frame by bolts. On the outside of the left longitudinal beam, the water tank and the water tank windshield are fixed on the upper wing surface of the left and right longitudinal beams of the frame. The disadvantage of this structure is that the layout space of the connecting plate is affected by the steering gear bracket and the front leaf spring bracket, and the elbow The gaps A and B between the beam and the windshield of the water tank are too small. When the windshield of the water tank vibrates, it is easy to generate dynamic interference with the beam of the bent pipe. At the same time, the connecting plates at both ends of the beam of the bent pipe are arranged The layout has a great influence

[0007] In summary, the existing two technical solutions are affected by the steering gear bracket and the front leaf spring bracket, and the spatial arrangement is very difficult, and the gaps A and B between the elbow beam and the water tank windshield are very small, usually Both are around 10mm, which will easily lead to dynamic interference between the two, and at the same time, the engine layout will be limited by space
