Description

Technical Field

[0001] The utility model relates to the technical field of automobile drive axles, in particular to a detachable upper thrust rod seat structure. Background Art

[0002] Currently, integrated drive axles for buses are multi-platform, with a small variety and low production. The suspensions of various OEMs continue to use the same platform as those for gasoline-powered vehicles, while the axle housing, as the supporting component of the electric drive axle and the connection interface with the entire vehicle, has a wide range of variations. The design, production, and quality of the suspension interface components directly affect the cost of the electric drive axle and the power consumption of the vehicle, and their production cycle is closely related to the production cycle of the entire vehicle. Figure 1 ), typically formed in one piece, requires extensive auxiliary welding tooling when welding to the axle housing, making the process cumbersome. Furthermore, most upper thrust rod seat structures are only suitable for axle housings with one axle load, preventing the upper thrust rod seat from being flexibly adjusted to accommodate different axle loads and eccentricities. This requires re-molding and casting a new upper thrust rod seat, which is costly. Utility Model Content

[0003] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0004] A detachable upper thrust rod seat structure includes a detachably connected upper seat and a base, and a plurality of bushings with different inner diameters; the upper seat is provided with a mounting hole for installing the bushing, and the base includes an assembly part for connecting with the upper seat and a processing part for connecting with the bridge housing.

[0005] Furthermore, the upper seat and the base are connected by a plurality of bolts.

[0006] Furthermore, the upper seat is provided with a plurality of first assembly holes for assembling bolts, and the assembly portion of the base is provided with a plurality of second assembly holes corresponding to the first assembly holes.

[0007] Furthermore, the assembly part and the processing part are integrally formed to form a base of a T-shaped structure, and reinforcing ribs are provided between the assembly part and the processing part.

[0008] Furthermore, the processed portion is fixedly connected to the bridge housing by welding.

[0009] Compared with the prior art, the beneficial effects produced by the present invention are:

[0010] 1. The utility model adopts a detachably connected upper seat and base to form an upper thrust rod seat structure. When welding to the bridge housing, the processing part of the base is first welded to the required position, and then the upper seat is assembled to the assembly part of the base. In this process, only the welding of the base requires auxiliary tooling, which is convenient for unifying the technical status, reducing the overall auxiliary workpieces, reducing the difficulty of assembly, and shortening the production cycle.

[0011] 2. The utility model adopts the same batch of upper seats and bases produced by the same mold. Bushings with different inner diameters can be installed in the mounting holes of the upper seats. The base can be processed and milled according to actual conditions to adapt to bridge shells with different axial loads and eccentricities. It has high flexibility in use, saves product mold development costs, and improves economic benefits. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The specific implementation of the present utility model will be described below with reference to the accompanying drawings.

[0020] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," "outer," "top," and "bottom" appear, they are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the device or component referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, if terms such as "first" and "second" appear, they are used solely for descriptive purposes and should not be construed as indicating or implying relative importance.

[0021] Reference Figure 2 、 Figure 3 and Figure 4 A detachable upper thrust rod seat structure includes a detachably connected upper seat 10 and a base 20, and several bushings 12 with different inner diameters. The upper seat 10 is provided with a mounting hole 11, in which one of the bushings 12 can be selectively installed. The base 20 includes an assembly portion 21 for connecting to the upper seat 10 and a processing portion 22 for fixedly connecting to the axle housing 40. Specifically, the upper seat 10 and the base 20 are screwed together using several bolts 30. The upper seat 10 is provided with a first assembly hole 13 for assembling the bolt 30, and the assembly portion 21 of the base 20 is provided with a second assembly hole 23 corresponding to the first assembly hole 13. Threads that cooperate with the bolt 30 can be provided in the second assembly hole 23. The processing portion 22 of the base 20 is fixed to the axle housing 40 by welding. In actual construction, the processing portion 22 can be milled according to factors such as the shape, axle load, and eccentricity of the axle housing 40 to adapt to axle housings 40 with different parameters, avoiding the frequent creation of different molds and saving mold opening costs.

[0022] Reference Figure 2 、 Figure 5 and Figure 6 The assembly portion 21 and processing portion 22 of the base 20 are integrally formed into a T-shaped structure. Reinforcing ribs 24 are provided between the assembly portion 21 and the processing portion to enhance the structural rigidity and strength of the base 20, preventing deformation or twisting when held, and optimizing the structural design. The interiors of the upper base 10 and base 20 are hollow, significantly reducing overall weight, facilitating lightweight applications while also lowering material costs.

[0023] When in use, the processing part 22 of the base 20 is first milled as required, and then the base 20 is welded and fixed to the bridge housing 40, and then the upper seat 10 is screwed to the base 20 by bolts 30, replacing the existing one-piece support 50 that is only applicable to one type of bridge housing 40 in the existing technology, reducing the tooling used in the process of welding to the bridge housing 40, unifying the technical status, reducing the processing difficulty, and shortening the production cycle.

[0024] The above is only a specific implementation method of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
