Technical Field
[0001] This utility model relates to the field of differential technology, specifically to a high-torque differential housing. Background Technology
[0002] With the continuous development of modern industry, the performance requirements for differentials are also increasing. Under some special working conditions, such as heavy trucks, off-road vehicles, and high-performance racing cars, differentials need to be able to withstand large torque inputs to ensure reliable operation of vehicles under heavy loads, high speeds, or complex road conditions. However, traditional differential housings often have some shortcomings under high torque conditions. On the one hand, due to the limitations of structural design, ordinary differential housings are difficult to guarantee output stability when operating at high speeds. When the vehicle faces situations such as rapid acceleration, rapid deceleration, or sharp turns, the internal components of the differential will be subjected to large impact forces, which may lead to fluctuations in power transmission and affect the vehicle's handling performance and driving safety.
[0003] On the other hand, existing differential housings present certain difficulties in disassembly and maintenance. The complex structural design makes it necessary to spend a lot of time and effort to repair or replace parts of the differential, increasing maintenance costs and downtime, which is not conducive to the efficient operation and maintenance of the equipment.
[0004] Publication number: CN207740418U. This high-torque differential housing for new energy vehicles eliminates the backlash between teeth through the elastic force of springs, ensuring the integrity of gear meshing, avoiding excessive backlash, preventing damage to the differential, facilitating the adjustment of clamping force, adjusting the backlash between teeth to a suitable range, making it easy for people to use, easy to disassemble, and easy to maintain the differential, thus improving the practicality of the device.
[0005] To address the aforementioned issues, such as increased internal impact during differential acceleration leading to wear and tear and wasted replacement time, we propose a high-torque differential housing. Utility Model Content

[0024] Structural Description: Housing 1: The overall shape is hemispherical with a hollow interior. It serves as the mounting base and protective shell for other differential components. It provides the necessary space for the internal gear transmission and fixing structure, while also bearing the forces generated by the operation of internal components and the external mounting and fixing forces.
[0025] Fixed shaft 1 2: Located at both ends of the outer side of housing 1, it is used to connect with components such as half shafts to transmit the power inside the differential to drive components such as wheels. Through cooperation with half shafts, the differential can adjust the speed of the left and right wheels according to the actual road conditions.
[0026] Fixed shaft 2 3: It is fixedly connected to the outside of the left drive gear 10. It mainly serves to support and fix the left drive gear 10, ensuring that the left drive gear 10 maintains a stable position during rotation and realizes accurate meshing and transmission with components such as the main gear 8.
[0027] Fixed bracket 4: Fixedly connected to the bottom of housing 1, it is an important structure for connecting and fixing the differential to other equipment or components. It is connected to the external structure through components such as connecting column 5, which enhances the overall stability of the differential housing and ensures that the differential will not shake or shift during operation.
[0028] Connecting column 5: One end is fixedly connected to the fixing frame 4, and the other end is internally slidably connected to a long rod 14. It serves to connect the fixing frame 4 and the long rod 14, and allows the long rod 14 to slide within a certain range, providing the necessary space for the operation of the fixing structure.
[0029] Push block 6: Fixedly connected to the outer top of the long rod 14. By operating push block 6, the long rod 14 can be moved, thereby adjusting the fixed structure. For example, when disassembling or installing internal components of the differential, pushing push block 6 can move the long rod 14, thereby changing the position of components such as the retainer 12, making it easier to operate the components.
[0030] Cylindrical 7: It is fixedly connected to the front end of the housing 1. It is hollow inside and has an annular slide 16 and an annular protrusion inside, which provides space for the installation and movement of components such as the fixing device 12. At the same time, it works with the fixing structure to realize the function of fixing and adjusting the internal components.
[0031] Main gear 8: Located inside housing 1, it meshes with the bottom of left drive gear 10 and right drive gear 11. It is a key component for differential power input, receiving power from the outside and transmitting it to left drive gear 10 and right drive gear 11 to achieve power distribution and differential function.
[0032] Iron ring 9: Fixedly connected inside the housing 1, with a hole in the center of the interior. Iron ring 9 is mainly used to support and fix components such as the left drive gear 10, which enhances the stability of the internal structure of the differential, reduces the shaking of the gear during rotation, and ensures the accuracy of power transmission.
[0033] Left drive gear 10: Rotatably connected inside housing 1, and fixedly connected to external fixed shaft 2 3. It meshes with main gear 8, receives power transmitted by main gear 8, and transmits power to left wheel through fixed shaft 2 3 and fixed shaft 1 2, realizing the driving and speed adjustment of left wheel.
[0034] Right drive gear 11: It is also rotatably connected inside the housing 1 and fixedly connected to the external shaft 2. Similar to the left drive gear 10, the right drive gear 11 meshes with the main gear 8, receives power and transmits power to the right wheel through the fixed shaft 2, and adjusts the speed of the right wheel according to the actual road conditions.
[0035] Fixture 12: Externally rotatably connected to the center of the cylinder 7, with one end rotatably connected to the arc-shaped disk 15. Fixture 12 plays a key fixing role in the fixing structure. Through cooperation with components such as the annular slide 16, it fixes and adjusts the components inside the differential, ensuring that the components will not loosen or shift under high-speed operation and high torque.
[0036] Spring 13: Sleeved on one end of the long rod 14, it is elastic. The function of spring 13 is to buffer the impact force on the internal components during the operation of the differential and protect the stability of the internal structure. When the components are subjected to external force, spring 13 can absorb some energy through its own compression or extension, reducing the collision and wear between components.
[0037] Long rod 14: One end is fitted with a spring 13, the top end is fixedly connected to a push block 6, and the other end is fixedly connected to a column. An arc-shaped disk 15 is fixedly installed at the front end of the column. The long rod 14 is an important component of the fixing structure. By moving it, the arc-shaped disk 15 and the fixing device 12 and other components can be driven to perform corresponding actions, so as to realize the fixing and disassembly of the internal components of the differential.
[0038] Arc-shaped disc 15: It is fixedly installed at the front end of the column at the end of the long rod 14, and is externally rotatably connected to a set of fixers 12. The shape and position design of the arc-shaped disc 15 allows the fixers 12 to rotate and move on its surface, thereby realizing multi-angle fixation and adjustment of internal components, improving the flexibility and adaptability of the fixing structure.
[0039] Annular slide 16: Fixedly connected inside the cylinder 7, with an annular groove at one end. The annular slide 16 provides a sliding track for components such as the retainer 12, allowing the retainer 12 to rotate and move flexibly inside the cylinder 7. It works with other components to achieve functions such as fixing, adjusting and disassembling the internal components of the differential.
[0040] When the vehicle turns or travels on uneven surfaces, the left and right wheels need to rotate at different speeds. At this time, the left drive gear 10 and right drive gear 11 will rotate at different speeds under the drive of the main gear 8, according to the actual road conditions. For example, when the vehicle turns right, the right wheel travels a relatively shorter distance, so the right drive gear 11 will rotate slower, while the left wheel travels a relatively longer distance, so the left drive gear 10 will rotate faster. In this way, the differential can automatically adjust the speed difference between the left and right wheels, ensuring that the wheels can travel in a pure rolling motion, reducing tire wear and the difficulty of vehicle handling. The iron ring 9 in the fixed structure is fixed inside the housing 1, providing a stable support point for components such as the left drive gear 10, allowing them to maintain a relatively stable position during rotation, reducing swaying and offset caused by high-speed rotation and high torque, and ensuring the stability and accuracy of power transmission. The push block 6, spring 13, long rod 14, and arc-shaped disc 15 in the fixed structure work together with the retainer 12. The spring 13 is sleeved on the long rod 14. On lever 14, when the internal components of the differential are subjected to external forces, spring 13 can buffer part of the impact force through its own elastic deformation, protecting the internal components. At the same time, the arc-shaped disc 15 and the retainer 12 at one end of the long lever 14 can adaptively adjust within the annular slide 16 and annular groove inside the cylinder 7 according to the movement state and force of the components, ensuring the fixing effect of the internal components and preventing the components from loosening or displacing under high torque and high speed. The various components of the high torque differential housing cooperate with each other to form a complete working system. The housing 1, as the overall support structure, provides installation and working space for the internal gears, fixing structures, etc. Bolts, nuts, fixing brackets 4, connecting columns 5 and other components ensure a stable connection between the housing and external components. During power transmission, the meshing transmission between the gears, the stable support of the fixing structure and the adaptive fixing function work together to enable the high torque differential to stably output power at high speed, realize the differential function, and meet the needs of the vehicle under various driving conditions.
[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
