Description

Technical Field

[0001] The utility model belongs to the technical field of bus accessories, and specifically relates to a fixing bracket of a front suspension stabilizer bar of a 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 8-meter full-load city bus front suspension stabilizer bar hanger fixing bracket is made of steel plates cut, bent, and punched according to the structure shown in the figure, and then installed into the corresponding mounting holes of the front suspension stabilizer bar hanger fixing bracket through the components of the front suspension stabilizer bar hanger assembly. The bending dimension of the structure in the height direction is too large, and the influence of the lateral torque released by the front suspension stabilizer bar hanger assembly on the bracket during operation is not taken into account, which is prone to the risk of disconnection from the bottom middle mounting hole of the bent part; only the upper part of the front and rear sides is connected to the moment tube in the frame part, and the left and right sides are open-type notch structures, which further aggravates the risk of this structural component breaking and failing from the bottom middle mounting hole. Utility Model Content

[0004] The utility model aims to provide a fixing bracket of a front suspension stabilizer bar of a full-load-bearing city bus, so as to solve the problem that the middle mounting hole at the bottom of the existing fixing bracket is easy to break.

[0005] The technical scheme adopted by the utility model is a fixing bracket of a front suspension stabilizer bar of a full-load-bearing city bus, comprising a fixing bracket body, the front, rear and side surfaces of the fixing bracket body are all welded with reinforcing rectangular tubes, and the reinforcing rectangular tubes are welded to the frame rectangular tubes.

[0006] Preferably, the left and right ends of the fixing bracket body are respectively bent upward to form a reinforcement portion, the reinforcement rectangular tube on the side of the fixing bracket is located outside the reinforcement portion and welded thereto, and the height of the reinforcement portion is lower than the height of the reinforcement rectangular tube.

[0007] Preferably, the fixing bracket body is 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 reinforced rectangular tube connected to the front, rear and side of the fixed bracket body is designed, and the reinforced rectangular tube is used to form a mechanical closed loop structure with the frame. The left and right mechanical structures are designed with bending, which solves the problem of the front suspension stabilizer bar hanger fixing bracket breaking at the bottom middle mounting hole. The fixed bracket body is made of 8mm thick Q355B steel plate through cutting, drilling and bending according to the design requirements, and the bending direction in the height direction is left and right bending and the bending height is low, so the structural strength is good.

[0013] The present invention will be further explained below in conjunction with the accompanying drawings to facilitate better understanding by those skilled in the art.

[0014] Example 1

[0015] like Figure 2-4 As shown, a fixing bracket of a front suspension stabilizer bar hanger of a full-load-bearing city bus includes a fixing bracket body 1. The fixing bracket body 1 is made of a Q355B steel plate with a thickness of 8 mm, and is made by cutting, drilling and bending according to design requirements. The front, rear and side surfaces of the fixing bracket body 1 are welded with reinforcing rectangular tubes 2, which are welded to the rectangular tubes of the frame. The connection between the reinforcing rectangular tubes 2 and the local part of the frame forms a mechanical closed-loop structure, which is beneficial to reducing the influence of the lateral torque released by the front suspension stabilizer bar hanger assembly during operation on the bracket; in addition, the left and right ends of the fixing bracket body 1 are respectively bent upward to form a reinforcing portion 3, and the reinforcing rectangular tubes 2 on the side of the fixing bracket 1 are located on the outside of the reinforcing portion 3 and welded thereto. The height of the reinforcing portion 3 is lower than the height of the reinforcing rectangular tubes 2, thereby improving the structural strength of the fixing bracket body 1 and solving the problem of the front suspension stabilizer bar hanger fixing bracket being broken at the position of the bottom middle mounting hole.

[0016] After the above structural parts are manufactured, they can be welded to the designated position of the rear section of the frame by using carbon dioxide gas shielded welding according to the designed position. When installing the front suspension stabilizer bar hanger assembly, install it into the mounting hole corresponding to the front suspension stabilizer bar hanger fixing bracket and tighten the fixing bolts on the upper part of the front suspension stabilizer bar hanger 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. Without departing from the design spirit and principle of the utility model, various modifications and improvements made by those skilled in the art to the technical solution of the utility model shall fall within the protection scope determined by the claims of the utility model.
