AI Technical Summary
The existing front shock absorber fixed bracket structure is too simple, and the impact of the lateral torque released by the front shock absorber assembly on the bracket is not effectively considered, resulting in the bracket being prone to breaking and lacking a mechanical closed-loop structure, which affects the reliability of the entire vehicle.
A fixed bracket based on the 8.6-meter fully load-bearing urban bus front shock absorber was designed, and the overall structure was formed by welding the U-shaped bottom plate and reinforcement plate, which added a contact surface with the frame partially welded to form a mechanical closed-loop structure.
By increasing the welding contact surface and forming a mechanical closed-loop structure, the overall structural strength of the fixed bracket is improved, the risk of fracture is reduced, and the operational reliability of the entire vehicle is improved.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of bus accessories, and in particular relates to a fixing bracket based on a front shock absorber of an 8.6-meter full-load-bearing city bus. Background Art
[0002] In recent years, pure electric city buses with full-body structures have appeared more and more in various cities across the country, and the good performance of the full-body structure has also been widely recognized; the full-body structure makes the bus driving more agile, stable, comfortable and safe. Taking into account the characteristics of the overall structure of the full-body structure, while ensuring the reliability of the overall structure of the full-body structure, the local design structure is reasonably adjusted and optimized to maximize the advantages.
[0003] like Figure 1 As shown, the existing front shock absorber fixing bracket uses a piece of steel plate, which is cut, bent, and punched according to the structure shown in the figure. After the manufacturing is completed, the upper single-side facades on the left and right sides are welded and connected with the local facades of the frame by carbon dioxide shielded welding. When installing the front shock absorber, the parts of the front shock absorber assembly are installed in the corresponding mounting holes of the fixing bracket. However, the structure is too simple and the bending size in the height direction is too large. The influence of the lateral torque released by the front shock absorber assembly during operation on the bracket is not considered, and there is a risk of disconnection from the bottom middle mounting hole of the bent part; and the connection between the front shock absorber fixing bracket and the local frame does not form a closed loop structure. When the vehicle runs for a long time or encounters bad road conditions, it will further increase the risk of such a front shock absorber fixing bracket breaking from the bottom middle mounting hole. Utility Model Content
[0004] In order to solve the above technical problems, the utility model provides a fixing bracket based on the front shock absorber of an 8.6-meter full-load-bearing city bus.
[0005] The technical solution adopted by the utility model is a fixing bracket based on the front shock absorber of an 8.6-meter full-load-bearing city bus, comprising a U-shaped bottom plate, a reinforcing plate 1 is welded to the front end of the U-shaped bottom plate, and a reinforcing plate 2 is welded to the rear end, the top end surface of the reinforcing plate 1 is flush with the U-shaped bottom plate, and the top end of the reinforcing plate 2 is located at one-third of the side plate of the U-shaped bottom plate.
[0006] Preferably, the height of the left side plate of the U-shaped bottom plate is greater than the height of the right side plate of the U-shaped bottom plate, an L-shaped notch is provided at the connection between the upper right side portion of the reinforcing plate 1 and the right side plate of the U-shaped bottom plate, the frame rectangular tube is located on the notch and is welded to the reinforcing plate 1 and the top end of the right side plate of the U-shaped bottom plate.
[0007] Preferably, the U-shaped bottom plate, the first reinforcing plate and the second reinforcing plate are all made of Q355B steel plate with a thickness of 8 mm.
[0008] Compared with the prior art, the beneficial effect of the utility model is that the U-shaped bottom plate, the reinforcement plate one and the reinforcement plate two are welded into a whole by carbon dioxide gas shielded welding, which increases the contact surface with the local welding of the frame and effectively forms a mechanical closed-loop structure. The overall structural strength is good, and the breakage of the front suspension stabilizer bar hanger fixing bracket from the bottom middle mounting hole is reduced, further increasing the reliability of the whole vehicle during operation. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 It is a schematic diagram of the structure of the existing front shock absorber fixing bracket;

[0012] The present invention will be further explained below in conjunction with the accompanying drawings to facilitate better understanding by those skilled in the art.
[0013] Example 1
[0014] like Figure 1-3 As shown, a fixing bracket based on the front shock absorber of an 8.6-meter full-load city bus includes a U-shaped bottom plate 1, a reinforcing plate 1 2 is welded to the front end of the U-shaped bottom plate 1, and a reinforcing plate 2 3 is welded to the rear end, the top end surface of the reinforcing plate 1 2 is flush with the U-shaped bottom plate 1, and the top end of the reinforcing plate 2 3 is located at one-third of the side plate of the U-shaped bottom plate 1. The U-shaped bottom plate 1, the reinforcing plate 1 2 and the reinforcing plate 2 3 are all made of Q355B steel plate with a thickness of 8 mm.
[0015] Furthermore, the height of the left side plate of the above-mentioned U-shaped bottom plate 1 is greater than the height of the right side plate of the U-shaped bottom plate 1, and an L-shaped notch 4 is opened at the connection between the upper right side portion of the reinforcing plate 2 and the right side plate of the U-shaped bottom plate 1. During assembly, the upper outer side portion of the left side plate of the U-shaped bottom plate 1 is welded to the frame rectangular tube, and another frame rectangular tube is located on the notch 4 and welded to the top end of the reinforcing plate 2 and the right side plate of the U-shaped bottom plate 1, thereby effectively increasing the welding area between the fixed bracket and the rectangular tube, and the overall structure has better strength when subjected to stress.
[0016] When installing the front shock absorber assembly, just install it into the corresponding mounting hole of the front shock absorber fixing bracket and tighten the fixing bolts on the upper part of the front shock absorber assembly together according to the torque.
[0017] The above-mentioned embodiments are only for describing the preferred implementation of the utility model, and are not intended to limit the scope of the utility model.
