Description

Technical Field

[0001] This utility model belongs to the field of mechanical manufacturing, and in particular relates to a differential housing that is easy to assemble. Background Technology

[0002] The differential is a crucial component of a vehicle's drivetrain, primarily used to allow the left and right drive wheels to rotate at different speeds when the vehicle is cornering. A differential typically consists of a series of gears, including one or more planetary gears, two side gears, and associated shafts and bearings. These components work together to allow the wheels to rotate at different speeds under varying conditions, while simultaneously transmitting power from the engine to the wheels. The differential housing is the outer shell that encloses and protects the internal mechanical components of the differential. It not only provides physical protection for the internal components but also helps to secure and position them, ensuring their proper functioning.

[0003] Traditional differential housings typically employ a modular rotating structure design to facilitate the insertion of internal gears, shafts, and bearings. While this design improves assembly convenience to some extent, in actual assembly scenarios, the individual housing modules are prone to detaching during the rotation and closure process. This results in an unstable housing structure, making it difficult to smoothly screw bolts into the bolt mounting holes for tightening. This not only significantly increases assembly difficulty but also severely impacts the overall assembly efficiency and connection quality of the differential housing.

[0004] Therefore, it is necessary to design a differential housing that is easy to assemble in order to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the shortcomings of traditional differential housings, which are prone to detachment during modular rotational closure, resulting in unstable housing structure, difficulty in bolt alignment, and low assembly efficiency, this utility model provides a differential housing that is easy to assemble.

[0006] This utility model is achieved through the following technical approach: a differential housing that is easy to assemble, comprising housing one, housing two, housing three, housing four, a first rotation point, and a second rotation point. Housing two and housing one are vertically distributed and are rotatably connected through the first rotation point on one side. Housing four and housing three are also vertically distributed and are rotatably connected through the second rotation point on one side. Housing one, housing two, housing three, and housing four together form a complete housing structure. Housing one, housing two, housing three, and housing four are each provided with multiple bolt mounting holes distributed along an arc shape. It also includes an arc-shaped locking rod, a locking block, and a spring. Each of the first and third housings has an arc-shaped locking hole. Each of the second and fourth housings has an arc-shaped locking rod fixedly connected to it. The arc-shaped locking rod on the second housing is inserted into the arc-shaped locking hole on the first housing, and the arc-shaped locking rod on the fourth housing is inserted into the arc-shaped locking hole on the third housing. Each of the first and third housings has a locking block slidably installed. A spring is fixedly connected between the locking block and the first or third housing. Each arc-shaped locking rod has a locking groove. The locking block on the first housing is inserted into the locking groove on the left arc-shaped locking rod, and the locking block on the third housing is inserted into the locking groove on the right arc-shaped locking rod.

[0007] Furthermore, it also includes locking bolts. Each arc-shaped lever has a locking hole. The locking hole on the left arc-shaped lever of housing one is threaded with the first locking bolt between housing three and housing three. The locking hole on the right arc-shaped lever of housing three is threaded with the second locking bolt. A through hole is opened on the upper side of housing one, and one end of the second locking bolt is located in the through hole.

[0008] Furthermore, one end of the arc-shaped lever has a flat-topped pyramidal structure with rounded corners at the top.

[0009] Furthermore, the end of the card block extending to the outside of housing one or housing three is designed as a pull ring structure.

[0010] Furthermore, the card block has a bevel.

[0011] Furthermore, the spring is a high-strength spring.

[0012] Beneficial effects: 1. By setting arc-shaped locking holes, arc-shaped locking rods, locking blocks, springs and locking grooves, the precise positioning and automatic locking functions between housing one, housing two, housing three and housing four are realized, which effectively prevents the housing structure from relatively separating after closing, enhances the stability of the entire housing structure, and provides a reliable guarantee for the subsequent bolts to be smoothly screwed into the bolt mounting holes and the tightening operation to be completed, thereby greatly improving the assembly efficiency and connection quality of the differential housing.

[0013] 2. By using the threaded connection between the locking bolts and locking holes, the connection strength between housing one, housing two, housing three and housing four is further strengthened after the housing structure is closed, avoiding loosening problems caused by vibration or impact, and improving the durability and safety of the differential housing under complex working conditions.

[0019] Example: A differential housing that is easy to assemble, such as Figures 1-4As shown, the structure includes a shell 1, a shell 2, a shell 3, a shell 4, a first rotation point 5, and a second rotation point 51. Shell 2 and shell 1 are vertically distributed and are rotatably connected via the first rotation point 5 on the left. Shell 4 and shell 3 are also vertically distributed and are rotatably connected via the second rotation point 51 on the right. Shells 1, 2, 3, and 4 together form a complete shell structure. Each of shells 1, 2, 3, and 4 has three bolt mounting holes 6 arranged along an arc shape. Two bolt mounting holes 6 aligned longitudinally form a group. The assembly includes a bolt, an arc-shaped locking rod 8, a locking block 9, and a spring 10. Each of the housing 1 and housing 3 has an arc-shaped locking hole 7. Each of the housing 2 and housing 4 has an arc-shaped locking rod 8 welded to it. The arc-shaped locking rod 8 on housing 2 is inserted into the arc-shaped locking hole 7 on housing 1. This insertion method positions housing 2 on housing 1. The arc-shaped locking rod 8 on housing 4 is inserted into the arc-shaped locking hole 7 on housing 3. This insertion method positions housing 4 on housing 3. One end of the arc-shaped locking rod 8 has a flat-topped pyramidal structure with a rounded corner at the top, ensuring that the arc-shaped locking rod 8 is properly inserted. During the insertion of the arc-shaped locking hole 7, the flat-topped pyramidal structure provides excellent guidance. Its rounded corners effectively reduce friction and resistance during insertion, preventing scratches and damage to the inner wall of the arc-shaped locking hole 7 caused by sharp edges. This ensures the arc-shaped locking rod 8 can be smoothly inserted into the arc-shaped locking hole 7. Each of the housing 1 and housing 3 has a sliding locking block 9. The end of the locking block 9 extending outside the housing 1 or housing 3 is designed as a pull ring for easy pulling by the user. The locking block 9 also has a beveled surface. When the arc-shaped locking rod 8 is inserted into the corresponding arc-shaped locking hole 7, the arc-shaped locking rod 8 can be pushed outward by the beveled surface against the corresponding locking block 9. A spring 10 is welded between body 1 and shell 3. There are a total of two springs 10, which provide a reset force for the two locking blocks 9. The springs 10 are strong springs. Each arc-shaped locking rod 8 has a locking groove 11. The locking block 9 on shell 1 is inserted into the locking groove 11 on the left arc-shaped locking rod 8 (i.e., the arc-shaped locking rod 8 on shell 2). Through this insertion method, the locking between shell 1 and shell 4 is achieved. The locking block 9 on shell 3 is inserted into the locking groove 11 on the right arc-shaped locking rod 8 (i.e., the arc-shaped locking rod 8 on shell 2). Through this insertion method, the locking between shell 3 and shell 2 is achieved.

[0020] like Figures 1-3As shown, it also includes locking bolts 12. Each arc-shaped lever 8 has a locking hole 13. The locking hole 13 on the first housing 1 and the left arc-shaped lever 8 is threaded with the first locking bolt 12 between the first housing 1 and the third housing 3. Through this threaded connection, the first housing 1 is locked onto the third housing 3. The locking hole 13 on the right arc-shaped lever 8 is threaded with the second locking bolt 12 between the third housing 3 and the right arc-shaped lever 8. Through this threaded connection, the fourth housing 4 is locked onto the third housing 3. A through hole 14 is opened on the upper left side of the first housing 1. The front end of the second locking bolt 12 is located in the through hole 14. In actual operation, the second locking bolt 12 can be loosened by simply inserting a screwdriver into the through hole 14.

[0021] When the differential housing needs to be used, the user first uses a screwdriver to unscrew the locking bolt 12, then pulls the latch 9 outward to disengage it from the latch 11 and compresses the spring 10. Then, rotate housing 2 counterclockwise and housing 4 clockwise to unfold the entire housing structure and form an open space, which is convenient for inserting internal components such as gears, shafts and bearings.

[0022] After placing the internal components, rotate housing 2 clockwise and housing 4 counterclockwise to close the housing structure. During the rotation, the arc-shaped locking rod 8 is inserted into the corresponding arc-shaped locking hole 7 to achieve the initial positioning between housing 1, housing 2, housing 3 and housing 4. At the same time, the arc-shaped locking rod 8 presses the locking block 9 to move outward until the arc-shaped locking rod 8 is fully inserted into the arc-shaped locking hole 7 and the locking groove 11 is aligned with the position of the locking block 9. At this time, the spring 10 returns to its original state and pushes the locking block 9 to re-insert into the locking groove 11, completing the self-locking between housing 1, housing 2, housing 3 and housing 4.

[0023] Finally, insert the prepared bolts into the longitudinally aligned bolt mounting holes 6 in sequence, tighten them with nuts, and then tighten the locking bolts 12 again to make the entire differential housing structure stably and reliably assembled together.
