Description

Technical Field

[0001] The invention relates to the technical field of automobile parts, and in particular to a gearbox suspension assembly. Background Art

[0002] With the rapid development of the automobile industry, the fuel consumption requirements for the whole vehicle are getting higher and higher. How to reduce fuel consumption has become one of the key factors that must be considered in the development of new models. Although there are many ways to reduce fuel consumption, such as the use of advanced engine technology, tire technology and other related technologies, these technologies will lead to increased costs. The emergence of lightweight design technology reduces the cost of the whole vehicle while reducing the weight of the whole vehicle, which in turn plays a role in reducing fuel consumption.

[0003] At present, the gearbox suspension assembly is mainly in the form of stamping parts, which are processed and manufactured using sheet metal parts. The design requirements of the external dimensions are achieved through a combination of stamping and welding processes to ensure that it matches the vehicle body. After welding, the overall electrophoresis method is used for rust prevention, but the surface roughness of the weld is poor, the electrophoresis quality is not high, and the gearbox suspension assembly will have rust problems. Summary of the invention

[0004] The object of the present invention is to provide a gearbox suspension assembly to solve the problems raised in the above background technology.

[0005] To achieve this object, the present invention adopts the following technical solutions:

[0006] A gearbox suspension assembly, comprising:

[0007] A connecting bracket, wherein the connecting bracket is provided with a mounting hole, a bushing assembly is arranged in the mounting hole, first connecting holes are provided on both sides of the connecting bracket, and the connecting bracket is made of a polymer material;

[0008] A support arm bracket, one end of which is connected to the bushing assembly, a second connecting hole is provided on the support arm bracket, and the support arm bracket is made of a polymer material.

[0009] Optionally, the connection bracket is provided with a plurality of first cavities, and the first cavities are provided on the connection bracket along the axial direction of the mounting hole.

[0010] Optionally, the connection bracket is provided with a plurality of second cavities, and the second cavities are provided on the connection bracket along the circumferential direction of the mounting hole.

[0011] Optionally, a plurality of reinforcing ribs are provided on the connecting bracket.

[0012] Optionally, the connecting bracket and the bushing assembly are injection molded using an in-mold injection molding process.

[0013] Optionally, the number of the second connecting holes is at least two.

[0014] Beneficial effects of the present invention:

[0015] The transmission suspension assembly provided by the present invention adopts polymer materials to make the connecting bracket and the support arm bracket. The polymer materials' own characteristics determine their resistance to salt water corrosion, thus avoiding the rust problem that may occur in the transmission suspension assembly. The polymer materials have poor thermal conductivity, and the heat generated by the transmission is not easily transferred to the bushing assembly, thus improving the durability of the bushing assembly. Moreover, by adopting polymer materials, the weight of the transmission suspension assembly can be reduced by 30% to 50% compared with the transmission suspension assembly made of general sheet metal parts or castings, thus meeting the lightweight requirements of the transmission suspension assembly and having a positive impact on fuel economy, power and safety performance.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0025] like Figure 1 As shown, the present invention provides a gearbox suspension assembly, including a connecting bracket 100 and a supporting arm bracket 200. The connecting bracket 100 is provided with a mounting hole 110, a bushing assembly 120 is arranged in the mounting hole 110, first connecting holes 130 are provided on both sides of the connecting bracket 100, and the connecting bracket 100 is made of a polymer material; one end of the supporting arm bracket 200 is connected to the bushing assembly 120, a second connecting hole 210 is provided on the supporting arm bracket 200, and the supporting arm bracket 200 is made of a polymer material.

[0026] The transmission suspension assembly provided by the present invention adopts polymer materials to make the connecting bracket 100 and the support arm bracket 200. The polymer materials themselves have salt water corrosion resistance, which avoids the rust problem that may occur in the transmission suspension assembly. The polymer materials have poor thermal conductivity, and the heat generated by the transmission is not easily transferred to the bushing assembly 120, thereby improving the durability of the bushing assembly 120. Moreover, by adopting polymer materials, the weight of the transmission suspension assembly can be reduced by 30% to 50% compared with the transmission suspension assembly made of general sheet metal parts or castings, thereby meeting the lightweight requirements of the transmission suspension assembly and having a positive impact on fuel economy, power and safety performance.

[0027] The connecting bracket 100 can be connected to the vehicle body through bolts and the first connecting hole 130, and the supporting arm bracket 200 can be connected to the gearbox through bolts and the second connecting hole 210. The number of the second connecting holes 210 is at least two to ensure the stability of the connection between the supporting arm bracket 200 and the gearbox. A plurality of reinforcing ribs 160 are provided on the connecting bracket 100, and by providing the reinforcing ribs 160, the structural strength of the connecting bracket 100 can be improved.

[0028] The connecting bracket 100 is provided with a plurality of first cavities 140, and the first cavities 140 are provided on the connecting bracket 100 along the axial direction of the mounting hole 110. Through the coordination between the polymer material properties of the connecting bracket 100 and the first cavities 140, the connecting bracket 100 can exhibit better damping characteristics, and the gearbox vibration is not easily transmitted to the vehicle body side through the gearbox suspension assembly, which is of great help to the improvement of the NVH performance of the whole vehicle. In addition, by setting the first cavity 140, the lightweight of the connecting bracket 100 can be improved.

[0029] The connecting bracket 100 is provided with a plurality of second cavities 150, and the second cavities 150 are provided on the connecting bracket 100 along the circumferential direction of the mounting hole 110. Through the coordination between the polymer material properties of the connecting bracket 100 and the second cavities 150, the connecting bracket 100 can exhibit better damping characteristics, and the gearbox vibration is not easily transmitted to the vehicle body side through the gearbox suspension assembly, which is of great help to the improvement of the NVH performance of the whole vehicle. In addition, by setting the second cavity 150, the lightweight of the connecting bracket 100 can be improved.

[0030] The connecting bracket 100 and the bushing assembly 120 are injection molded by the in-mold injection molding process, which can ensure that the connecting bracket 100 and the bushing assembly 120 meet the high-precision requirements during the assembly process, and at the same time can compensate for the dimensional deviation of the bushing assembly 120 itself. The in-mold injection molding process is used to achieve direct injection molding of the connecting bracket 100 and the bushing assembly 120, and avoid failure of the connection between the connecting bracket 100 and the bushing assembly 120. At the same time, since the connecting bracket 100 is directly injection molded, the production efficiency is high, the position and size of each hole and the mounting surface are more accurate, and the assembly quality of the whole vehicle is greatly improved. Of course, in other embodiments, the bushing assembly 120 and the support arm bracket 200 can also be injection molded by the in-mold injection molding process to achieve direct injection molding of the bushing assembly 120 and the support arm bracket 200.

[0031] By using polymer materials to make the connecting bracket 100 and the support arm bracket 200, the lightweight design requirements of the gearbox suspension assembly are met; by changing the molding process of the gearbox suspension assembly, compared with the traditional split structure installation and matching, the high-precision processing requirements required for the matching of the connecting bracket 100 and the bushing assembly 120 are met; by combining the properties of polymer materials with the structural optimization of the gearbox suspension assembly, the gearbox suspension assembly exhibits better damping characteristics, thereby improving the NVH performance of the entire vehicle.
