Description

Technical Field

[0001] This utility model relates to the field of differential technology, specifically to a high-strength differential ductile iron shell component. Background Technology

[0002] The differential is a key component of a car's drive axle. Its main function is to allow the left and right drive wheels to rotate at different speeds while transmitting power. When a vehicle turns, the turning radius of the inner and outer wheels differs, resulting in different travel distances. The differential automatically adjusts the speed difference between the left and right wheels, reducing the speed of the inner wheel and increasing the speed of the outer wheel. This ensures smooth cornering, prevents wheel slippage and sideslip, and improves vehicle handling and stability.

[0003] The differential housing is made of ductile iron. It combines the material properties of ductile iron with the structural and functional requirements of the differential housing. It has high strength, good toughness and wear resistance, and can withstand various stresses and impacts during vehicle operation, ensuring the normal operation of the differential and effectively extending its service life.

[0004] When existing differentials are lubricated, lubricating oil is usually delivered to each lubrication point through lubrication channels located on the differential housing. However, during the delivery of lubricating oil in the channels, it is easily leaked or lost due to vehicle bumps. This increases the amount of lubricating oil used, resulting in insufficient lubrication at the contact points between the spherical iron housing and the gears. This exacerbates the wear of the spherical iron housing and ultimately reduces its strength. Utility Model Content

[0005] The purpose of this utility model is to provide a high-strength differential ductile iron shell component.

[0006] To achieve this objective, the present invention adopts the following technical solution:

The heat dissipation mechanism is fixedly installed on the differential housing and is used to dissipate heat from the differential. The lubrication mechanism includes a sealing mechanism, which is fixedly installed on the differential housing and is used to seal the lubrication mechanism.

[0008] Furthermore, the lubrication mechanism also includes an oil inlet pipe and a ball. An annular oil groove is provided on the differential housing. The oil inlet pipe is fixedly installed on the differential housing and is connected to the annular oil groove. An annular groove is provided on the differential housing. The ball is rotatably installed on the annular groove. The annular groove and the annular oil groove are connected through an oil outlet. The oil inlet pipe is fixedly connected to a sealing mechanism, which is used to seal the oil inlet pipe.

[0009] Furthermore, the sealing mechanism includes a cover, a pipe joint, and a sealing gasket. The pipe joint is fixedly installed on the differential housing and is fixedly connected to the oil inlet pipe. The sealing gasket is fixedly installed on the cover and is inserted into the pipe joint.

[0010] Furthermore, the sealing mechanism also includes a locking block and a spring. A locking groove is provided on the cover. One end of the spring is fixedly connected to the pipe joint, and the other end of the spring is fixedly connected to the locking block. The locking block is slidably connected to the pipe joint, and the locking block engages with the locking groove.

[0011] Furthermore, the heat dissipation mechanism includes a mounting bracket, a heat dissipation plate, and heat dissipation fins.

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of this utility model, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0025] Reference Figures 1 to 2The diagram illustrates a high-strength differential ductile iron housing, comprising a differential housing 1, a lubrication mechanism 2, and a heat dissipation mechanism 3. The lubrication mechanism 2 is fixedly installed on the differential housing 1 and serves to lubricate the differential. Through the lubrication mechanism 2, the differential housing 1 is effectively lubricated, preventing excessive wear and reduced strength. The heat dissipation mechanism 3 is fixedly installed on the differential housing 1 and serves to dissipate heat from the differential. Through the heat dissipation mechanism 3, the differential housing 1 is effectively cooled, preventing any impact on the mechanical properties of the ductile iron in the differential housing 1. The lubrication mechanism 2 includes a sealing mechanism 26, which is fixedly installed on the differential housing 1 and serves to seal the lubrication mechanism 2. Through the sealing mechanism 26, the oil inlet pipe 22 is sealed, preventing lubricating oil leakage.

[0026] Reference Figures 1 to 5 The lubrication mechanism 2 also includes an oil inlet pipe 22 and a ball 25. An annular oil groove 21 is provided on the differential housing 1 for storing lubricating oil. The oil inlet pipe 22 is fixedly installed on the differential housing 1 and communicates with the annular oil groove 21, allowing lubricating oil to be added into the annular oil groove 21. An annular groove 23 is provided on the differential housing 1 to limit the movement of the ball 25. The ball 25 is rotatably mounted on the annular groove 23. The rotation effect of ball 25 can evenly spread the lubricating oil carried on ball 25 to the contact point between differential housing 1 and differential gear. The annular groove 23 and annular oil groove 21 are connected by oil outlet 24. Ball 25 contacts oil outlet 24, and the lubricating oil in annular oil groove 21 can be carried out by ball 25 through oil outlet 24. Oil inlet pipe 22 is fixedly connected to sealing mechanism 26. Sealing mechanism 26 is used to seal oil inlet pipe 22 to prevent lubricating oil in annular oil groove 21 from flowing out of oil inlet pipe 22.

[0027] Reference Figures 2 to 6 The sealing mechanism 26 includes a cover 261, a pipe joint 262, and a sealing gasket 263. The pipe joint 262 is fixedly installed on the differential housing 1 and is fixedly connected to the oil inlet pipe 22. The pipe joint 262 limits the cover 261, keeping it fixed. The sealing gasket 263 is fixedly installed on the cover 261, and the cover 261 is inserted into the pipe joint 262. When the cover 261 is inserted into the pipe joint 262, it will squeeze the sealing gasket 263, causing the sealing gasket 263 to expand and deform, thereby sealing the cover 261 and the pipe joint 262.

[0028] Reference Figure 6The sealing mechanism 26 also includes a locking block 264 and a spring 265. A locking groove 266 is provided on the cover 261. One end of the spring 265 is fixedly connected to the pipe joint 262, and the other end of the spring 265 is fixedly connected to the locking block 264. Through the elastic force of the spring 265, the locking block 264 is kept locked with the locking groove 266 without external force, thereby limiting the cover 261. The locking block 264 is slidably connected to the pipe joint 262, and the locking block 264 is locked with the locking groove 266. Through the sliding effect of the locking block 264, the locking block 264 and the locking groove 266 are locked or released.

[0029] Reference Figure 2 and Figure 7 The heat dissipation mechanism 3 includes a fixing frame 31, a heat dissipation plate 33, and heat dissipation fins 34. The fixing frame 31 is fixedly installed on the differential housing 1 and is used to fix the heat dissipation plate 33. The heat dissipation fins 34 are fixedly installed on the heat dissipation plate 33. Multiple heat dissipation fins 34 are provided to increase the contact area between the heat dissipation plate 33 and the air, thereby improving the heat dissipation effect of the heat dissipation plate 33. The heat dissipation plate 33 is inserted into the fixing frame 31. By installing the heat dissipation plate 33 on the differential housing 1, it can dissipate heat from the differential housing 1. The heat dissipation fins 34 have ventilation holes 35. The diameter of the ventilation holes 35 gradually decreases from bottom to top. Through the ventilation holes 35, air can pass through the heat dissipation fins 34. Due to the shape of the ventilation holes 35 being wider at the bottom and narrower at the top, the airflow speed in the ventilation holes 35 is increased, thereby further improving the heat dissipation effect of the heat dissipation plate 33.

[0030] Reference Figure 7 The heat dissipation mechanism 3 also includes a wedge 36 and a limiting spring 37. One end of the limiting spring 37 is fixedly installed on the heat dissipation plate 33, and the other end of the limiting spring 37 is fixedly connected to the wedge 36. Through the elastic force of the limiting spring 37, the wedge 36 is always engaged with the limiting groove 32 without external force, thereby limiting the heat dissipation plate 33 and keeping it fixed. The fixing frame 31 has a limiting groove 32. The wedge 36 can be slidably installed on the heat dissipation plate 33. Through the sliding effect of the wedge 36, the wedge 36 can engage or disengage with the limiting groove 32, and the wedge 36 is engaged with the limiting groove 32.

[0031] This high-strength differential ductile iron housing, through the inclusion of lubrication and sealing mechanisms, ensures uniform lubrication between the ductile iron housing and the gear contact points, and provides excellent sealing for the annular oil groove, preventing lubricant leakage. This enhances the strength and lubrication performance of the ductile iron housing. Furthermore, the included heat dissipation mechanism effectively cools the housing, preventing overheating that could affect the mechanical properties of the ductile iron and further improving its heat dissipation and strength.

[0032] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
