Description

Technical Field

[0001] The utility model relates to the technical field of automobile manufacturing, and particularly relates to an integrated lower cover plate of a vehicle bridge. Background Technique

[0002] With the progress of vehicle manufacturing technology and the promotion of the lightweight trend, the design of the lower cover plate of the vehicle bridge has gradually evolved from a traditional independent support structure to an integrated multi-functional component. At present, the rear air suspension on buses generally has a straight beam structure or a C-shaped beam structure. The beam body is connected and fixed to the vehicle bridge by passing a U-bolt through the vehicle bridge plate support and the beam body at the same time, so as to realize the transmission of the suspension load. It is usually a four-airbag structure, which occupies a large space and has many parts, and the structure is relatively complex, resulting in a high cost.

[0003] In the prior art, with the increasing demand for the interior space of each vehicle factory and the consideration of the overall vehicle cost, the two-airbag rear air suspension has gradually developed. However, the upper and lower connection plates of the existing four-airbag are not suitable for the connection between the two-airbag air suspension and the vehicle bridge. This problem can be solved by the upper and lower cover plates of the vehicle bridge to realize the layout of the two-airbag rear air suspension.

[0004] Based on this, an integrated lower cover plate of a vehicle bridge is now provided, which can eliminate the drawbacks of the existing device. Content of the Utility Model

[0005] The purpose of the utility model is to provide an integrated lower cover plate of a vehicle bridge to solve the problems in the background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] An integrated lower cover plate of a vehicle bridge, comprising: a body;

[0008] A docking surface, which is arranged on the top of the body, and positioning pin mounting holes are arranged on the outer surface of the docking surface;

[0010] A support assembly, which is fixedly arranged on the outer surface of the body and is used for strengthening the structure of the lower cover plate.

[0011] On the basis of the above technical solutions, the utility model also provides the following optional technical solutions:

[0012] In an optional solution: the connection assembly includes a mounting protrusion, the mounting protrusion is arranged on the outer surface of the body, a vehicle bridge connection hole is arranged on the outer surface of the mounting protrusion, and a weight reduction through hole is arranged on the top of the body.

[0013] In an alternative solution: The support assembly includes reinforcing ribs fixedly arranged on the outer surface of the body. A suspension rod mounting seat is fixedly connected to the right side of the reinforcing rib. A suspension rod mounting hole is formed on the outer surface of the suspension rod mounting seat. A shock absorber mounting seat is fixedly connected to the top of the suspension rod mounting seat. A shock absorber mounting hole is formed on the outer surface of the shock absorber mounting seat.

[0014] In an alternative solution: A thrust rod mounting seat is fixedly connected to the bottom of the body. A thrust rod mounting hole is formed on the outer surface of the thrust rod mounting seat.

[0015] In an alternative solution: A cavity is formed inside the body.

[0016] In an alternative solution: The body is made of low-alloy high-strength steel.

[0017] In an alternative solution: Wear-resistant materials are provided on both the connecting surface and the outer surface of the reinforcing ribs.

[0018] In an alternative solution: A buffer layer is provided on the surface of the cavity.

[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0020] 1. By integrating the axle connection hole, shock absorber mounting hole, suspension rod mounting hole and thrust rod mounting hole into one, the present utility model effectively fixes various components. Compared with the traditional rear suspension structure, the suspension space occupation is significantly optimized, further improving the interior space of the vehicle. At the same time, the lower cover plate is designed with weight-reducing through holes, which greatly reduces the weight of the lower cover plate body and achieves the lightweight goal on the premise of ensuring the structural strength.

[0021] 2. Through the fixing method of the reinforcing ribs, the integrated axle lower cover plate of the present utility model does not require an additional suspension rod mounting bracket, which not only meets the installation requirements but also ensures the strength. At the same time, the lower cover plate is designed with a locating pin mounting hole, and a locating pin can be added during installation as needed. This design can further enhance the strength of the suspension and effectively prevent the axle from shifting. Such improvements not only simplify the structure, reduce the number of components, but also improve the stability and safety of the overall suspension system. BRIEF DESCRIPTION OF THE DRAWINGS
