Description

Technical Field

[0001] The utility model relates to the technical field of shuttle buses, in particular to a lightweight structure of a cross beam of a shuttle bus. Background Technique

[0002] At present, air suspensions are generally used in shuttle buses. In order to ensure the convenience of getting on and off the low floor of the shuttle bus, a wheel-end motor drive mode is adopted. The middle part of the vehicle sinks to increase the passenger area, and a disconnected axle is used. The left and right wheel ends and the suspension are connected by a concave cross beam.

[0003] At present, the traditional chassis structure is heavy, and the bolt connections are easy to loosen. Due to the downward pressure exerted by the wheel ends on the vehicle during driving and the thrust exerted by the thrust rod during braking, the existing stiffness becomes poor (large force, uneven force), and it is easy to deform, resulting in large uneven wear of the tires.

[0006] The cross beam structure includes an intermediate support plate. Four connecting pipes are installed on the intermediate support plate, and the four connecting pipes are arranged in parallel. The ends of the four connecting pipes are all connected through fixed pipe supports. A thrust support is installed on one of the connecting pipes on the side.

[0007] Preferably, mounting plates are installed at the tops of both ends of the C-shaped beam, and shock absorbers are installed on the mounting plates.

[0008] Preferably, a fixing bracket is installed on the C-shaped beam, and the fixing bracket is fixed to the C-shaped beam through fixing bolts.

[0009] Preferably, the fixed pipe support is fixedly welded to the C-shaped beam.

[0010] Preferably, the connecting pipe is a circular pipe.

[0011] Preferably, the intermediate support plate includes an intermediate plate and side plates on both sides of the intermediate plate, and the side plates and the intermediate plate are respectively located between two adjacent connecting pipes.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] It has large stiffness and light weight, and the bending and torsion resistance capabilities of the chassis assembly are improved.

[0014] Under the same working conditions, the new structure of this tubular crossbeam distributes part of the stress of the C-shaped beam, and the maximum stress value decreases by 20%; in addition, the product is lightweight and the weight is reduced by 30%. Description of the Drawings

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-3 , the present utility model provides a technical solution: a lightweight structure for a ferry truck crossbeam, including a crossbeam structure 1 and a C-shaped beam 2. There are two C-shaped beams 2, and the two C-shaped beams 2 are respectively installed at both ends of the crossbeam structure 1;

[0021] The crossbeam structure 1 includes an intermediate support plate 11. Four connecting pipes 12 are installed on the intermediate support plate 11, and the four connecting pipes 12 are arranged in parallel. The ends of the four connecting pipes 12 are all connected through a fixed pipe support 13. A thrust support 14 is installed on one of the connecting pipes 12 located on the side.

[0022] In the present utility model, mounting plates 3 are installed at the tops of both ends of the C-shaped beam 2, and shock absorbers are installed on the mounting plates 3.
