Description

Technical Field

[0001] This utility model relates to the field of forging technology, and in particular to a high-strength spherical shell forging. Background Technology

[0002] With the continuous development of the automotive industry, the powertrain and transmission systems of automobiles are becoming increasingly complex. The differential, in particular, plays a crucial role as a vital component of the vehicle's transmission system. The primary function of the differential is to distribute power to the drive shaft based on the speed differences between the wheels during cornering, thereby ensuring smooth vehicle operation. The differential ball housing, as one of the key components of the differential, directly affects its performance and lifespan through its design and manufacturing.

[0003] Differentials generate significant friction and heat during operation, especially under high-speed driving and complex driving conditions. The ball housing, as the load-bearing component of the differential, must not only withstand these frictional and impact forces but also effectively dissipate heat. Existing differential ball housings primarily rely on the thermal conductivity of the housing material to facilitate heat conduction and dissipation, and secondly, on airflow outside the differential to remove heat. However, in some high-performance vehicles or under heavy-load operating conditions, traditional heat dissipation designs may not meet the requirements. Therefore, a high-strength ball housing forging is proposed to address these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a high-strength spherical shell forging, which aims to improve the limited heat dissipation effect of traditional heat dissipation methods in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-strength spherical shell forging includes a shell, a connection port one at the top of the shell, a connection port two in the middle of the shell, a connection port three at the bottom of the shell, a flange fixedly connected to the outer periphery of the shell, a sliding groove in the middle of the flange, an airflow guide groove in the outer periphery of the shell, and a turbulence protrusion in the middle of the airflow guide groove.

[0007] As a further description of the above technical solution:

[0008] The inner wall of the housing is provided with multiple main oil passages and multiple branch oil passages.

[0009] As a further description of the above technical solution:

[0010] The top of the flange is fixedly connected with a reinforcing rib;

[0011] As a further description of the above technical solution:

[0012] The main oil passages are respectively connected to the branch oil passages;

[0013] As a further description of the above technical solution:

[0014] The spacing between the airflow guide grooves increases from top to bottom;

[0015] As a further description of the above technical solution:

[0016] Both the main oil passage and the branch oil passage are arc-shaped.

[0017] This utility model has the following beneficial effects:

[0018] 1. In this utility model, during vehicle operation, the airflow guide groove on the surface of the housing matches the airflow direction during vehicle operation, causing the airflow to flow in the middle of the airflow guide groove, thereby improving the heat dissipation effect of the vehicle during operation and ensuring the performance and service life of the housing.

[0019] 2. In this utility model, the flow resistance of lubricating oil inside the housing is reduced by the main oil passage, thereby improving the utilization efficiency of lubricating oil inside the housing. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-3 An embodiment of this utility model provides a high-strength spherical shell forging, including a shell 1. The top of the shell 1 is provided with a connection port 4, the middle of the shell 1 is provided with a connection port 5, the bottom of the shell 1 is provided with a connection port 3 9, a flange 2 is fixedly connected to the outer periphery of the shell 1, a sliding groove 3 is provided in the middle of the flange 2, an airflow guide groove 6 is provided on the outer periphery of the shell 1, a turbulence protrusion 8 is provided in the middle of the airflow guide groove 6, and the spacing of the airflow guide groove 6 increases from top to bottom. Firstly, thanks to the pre-designed airflow guide grooves 6, the airflow guide grooves 6 on the surface of the housing 1 match the airflow direction during vehicle operation, causing the airflow to accelerate in the middle of the airflow guide grooves 6, thus improving the heat dissipation effect of the airflow on the surface of the airflow guide grooves 6. At the same time, the turbulence effect is enhanced by the turbulence protrusions 8, thereby further improving the heat dissipation effect of the vehicle during operation, thus ensuring the performance and service life of the housing 1. Since more heat is generated by friction at the drive shaft connection, the distribution of the airflow guide groove spacing 6 makes the connection port 4 at the drive shaft connection of the housing 1 dissipate heat faster.

[0027] Reference Figure 2 The inner wall of the housing 1 has multiple main oil passages 10 and multiple branch oil passages 11. The main oil passages 10 are connected to the branch oil passages 11, and both the main oil passages 10 and the branch oil passages 11 are arc-shaped. The main oil passages 10 reduce the flow resistance of lubricating oil inside the housing 1, while ensuring that the lubricating oil is distributed in a laminar flow state, avoiding insufficient oil pressure caused by turbulence, thereby improving the utilization efficiency of lubricating oil in the housing 1. At the same time, the arc-shaped main oil passages 10 and branch oil passages 11 facilitate the mutual flow of lubricating oil between the main oil passages 10 and the branch oil passages 11.

[0028] Reference Figure 1 A reinforcing rib 7 is fixedly connected to the top of flange 2. The reinforcing rib 7 enhances the structural strength of flange 2, thereby preventing flange 2 from being damaged due to excessive torque during vehicle operation.

[0029] Working principle: During vehicle operation, the airflow guide grooves 6 on the surface of the housing 1 match the airflow direction during vehicle operation, causing the airflow to flow in the middle of the airflow guide grooves 6. At the same time, the turbulence effect is enhanced by the turbulence protrusions 8, thereby improving the heat dissipation effect of the vehicle during operation, and thus ensuring the performance and service life of the housing 1.

[0030] The main oil passage 10 reduces the flow resistance of lubricating oil inside the housing 1, while ensuring that the lubricating oil is distributed in a laminar flow state, avoiding insufficient oil pressure caused by turbulence, thereby improving the utilization efficiency of lubricating oil inside the housing 1.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
