Description

Technical Field

[0001] The utility model belongs to the technical field of bus accessories, and in particular relates to a bracket based on a rear suspension stabilizer bar hanger of a 7-meter full-load-bearing city bus. Background Art

[0002] The structure of the existing rear suspension stabilizer bar hanger fixing bracket is as follows: Figure 1 As shown, a 6mm thick steel plate is used, which is cut, bent, and punched according to the structure shown in the figure, and a 6mm thick reinforcement plate is welded on both sides. Finally, it is welded to a whole component by carbon dioxide gas shielded welding; when it is installed in the vehicle design, it is welded to the designated position of the frame. When installing the rear suspension stabilizer bar hanger assembly, the parts of the rear suspension stabilizer bar hanger assembly are installed into the corresponding installation holes of the rear suspension stabilizer bar hanger fixing bracket body.

[0003] The above structure has the following disadvantages:

[0004] 1. This structural part is made of 6mm thick steel plate with one side open. The effect of the lateral moment released by the rear suspension stabilizer bar assembly during operation on its stress is not taken into account, which may lead to the risk of disconnection from the middle mounting hole at the bottom of the bent part.

[0005] 2. The connection between the assembly structure and the local frame is only single-sided welding, and the connection with the local frame does not form a closed-loop structure. When this structure is subjected to stress for a long time, the rear suspension stabilizer bar hanger fixing bracket body and the rectangular tube in the local frame are only single-sided contact welded, which can easily cause side tearing of the rectangular tube at the welding contact position, resulting in overall failure. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a bracket based on the rear suspension stabilizer bar hanger of a 7-meter full-load-bearing city bus.

[0007] The technical solution adopted by the utility model is a bracket based on the rear suspension stabilizer bar hanger of a 7-meter full-load-bearing urban bus, including a bracket body, the bracket body is in the shape of a trapezoidal plate, and two sides of the bracket body are respectively welded with a reinforced rectangular tube 1 and a reinforced rectangular tube 2, the reinforced rectangular tube 1 and the reinforced rectangular tube 2 are welded to the frame, and a mounting hole is opened in the center of the bracket body.

[0008] Preferably, the upper edge and the bottom edge of the bracket body are both bent upward to form a reinforcement portion.

[0009] Preferably, the bracket body is made of Q355B steel plate with a thickness of 8 mm.

[0010] Compared with the prior art, the beneficial effect of the utility model is that the bracket body with a trapezoidal structure is connected to the frame rectangular tube, and its front and lateral connections with the frame part form a mechanical closed-loop structure, and the bracket body itself has a bent mechanical structure, which prevents the front suspension stabilizer bar hanger fixing bracket from breaking at the position of the bottom middle mounting hole; there are relatively few parts in the design structure, and it is made of 8 mm thick plate by bending, which greatly improves the processing efficiency of parts and effectively reduces the price of parts, and the structure is simple and the overall strength is good. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 2 It is a schematic diagram of the structure of the utility model;

[0013] Figure 3 It is a schematic diagram of the structure of the bracket body;

[0014] Figure 4 It is a schematic diagram of the assembly of the utility model. DETAILED DESCRIPTION

[0015] The present invention will be further explained below in conjunction with the accompanying drawings to facilitate better understanding by those skilled in the art.

[0016] Example 1

[0017] like Figure 1-4 As shown, a bracket based on the rear suspension stabilizer bar hanger of a 7-meter full-load-bearing city bus includes a bracket body 1. The bracket body 1 is in a trapezoidal plate shape and is made of a Q355B steel plate with a thickness of 8 mm. A reinforcing rectangular tube 1 2 and a reinforcing rectangular tube 2 3 are welded to both sides of the bracket body 1. The reinforcing rectangular tube 1 and the reinforcing rectangular tube 2 3 are welded to a specified position of the rear section of the frame by using carbon dioxide gas shielded welding. A mounting hole is provided in the center of the bracket body 1 for connecting the rear suspension stabilizer bar hanger. The upper and lower sides of the bracket body are bent upward to form a reinforcing portion 4.

[0018] When installing the rear suspension stabilizer bar hanger assembly, simply install it into the corresponding mounting hole of the rear suspension stabilizer bar hanger fixing bracket and tighten the fixing bolts on the upper part of the rear suspension stabilizer bar hanger assembly together according to the torque.

[0019] The utility model structure has the following advantages:

[0020] 1. Only one piece of Q355B steel plate with a thickness of 8mm is used, and it is made by cutting, drilling and bending according to the design requirements. It has a simple structure and good overall strength.

[0021] 2. The front and side designs of the rear suspension stabilizer bar hanger fixing bracket in this new structure have a reinforced moment tube connected to the local connection of the frame, which effectively forms a mechanical closed-loop structure, and is designed with a bent mechanical structure, which completely eliminates the situation that the front suspension stabilizer bar hanger fixing bracket breaks at the bottom middle mounting hole;

[0022] 3. This new structure has relatively few parts and is made of 8 mm thick plate by bending, which greatly improves the processing efficiency of parts and effectively reduces the price of parts.

[0023] By rationally adjusting the overall design structure of the rear suspension stabilizer bar hanger fixing bracket assembly, the reliability and durability of the vehicle operation are improved, while also meeting the harsh conditions of long-term overload operation of urban buses, and greatly reducing the maintenance and use costs of the vehicle.

[0024] 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.
