Description

Technical Field

[0001] This utility model relates to the technical field of differential housing structure, specifically a lightweight integrated differential housing structure. Background Technology

[0002] A car differential is a mechanism that enables the left and right or front and rear drive wheels to rotate at different speeds. It mainly consists of left and right half-shaft gears, two planetary gears and a gear carrier. Its function is to enable the left and right wheels to roll at different speeds when the car is turning or driving on uneven roads, that is, to ensure that the drive wheels on both sides perform pure rolling motion.

[0003] For example, Chinese patent CN214274395U discloses a differential housing with a protective structure, including a first housing, a second housing fixedly connected to one side of the first housing by fixing bolts, a protective plate snapped into the bottom of the first housing, two limiting grooves opened inside the protective plate, limiting sliders rotatably connected inside the two limiting grooves, and a fixing head fixedly connected to the top of the limiting sliders, and a fixing groove for cooperating with the fixing head opened inside the first housing; compared with the prior art, the beneficial effect of this utility model is that it can protect the differential housing exposed to the outside, thereby effectively avoiding damage caused by the car passing through rough roads with many potholes and protruding stones. This design addresses the occasional scraping and damage to the differential housing. The ability to quickly install and remove the protective plate is simple, convenient, time-saving, and labor-saving, improving the stability of the fixed protective plate and enhancing its practicality. However, traditional differential housing structures use flanges to connect the first and second housings, which are then bolted together. During use, the first and second housings are susceptible to vibration, causing the bolts to loosen and resulting in a loose flange connection. This allows impurities to enter the housing, affecting the transmission of internal gears. Therefore, a lightweight, integrated differential housing structure is proposed to solve these problems.

[0005] To address the shortcomings of existing technologies, this utility model provides a lightweight integrated differential housing structure, which has advantages such as stable connection between housings and solves the problem of loosening of traditional connection parts.

[0006] (II) Technical Solution

[0007] To achieve the aforementioned goal of stable connection between housings, this utility model provides the following technical solution: a lightweight integrated differential housing structure, comprising:

[0008] A first housing, one end of which is integrally connected to a first flange, and a plurality of bolt seats are integrally fixedly installed on the outer surface of the first flange;

[0009] The second housing is disposed at one end of the first housing. A second flange is integrally connected to one end of the second housing, and a positioning component is disposed between the second flange and the positioning groove.

[0010] Preferably, the positioning component includes a positioning ring integrally connected to one side of the first flange, and a positioning groove matching the positioning ring is formed on the outer surface of one side of the second flange. The positioning ring on one side of the first flange is positioned and connected to the positioning groove on the second flange, thereby increasing the stability and sealing of the connection between the first flange and the second flange.

[0011] Preferably, the outer surfaces of the first flange, the bolt seat, and the second flange are all provided with threaded holes of the same size. A fixing bolt is installed in the threaded hole of the bolt seat, and one end of the fixing bolt passes through the first flange and the second flange. By setting the bolt seat on the first flange, the connection between the fixing bolt and the first flange is increased, thereby increasing the firmness of the connection between the fixing bolt and the second flange.

[0012] Preferably, the first housing is integrally connected to the two sides of the shaft seat, and one end of the first housing is integrally connected to the sleeve, which can protect the installed input shaft and output shaft, and at the same time increase the stability of the transmission process of the input shaft and output shaft, and prevent the input shaft from shaking during rotation.

[0013] Preferably, gear seats are integrally installed on both sides of the inner wall of the first housing, which increases the stability of the bevel gear transmission.

[0014] Preferably, both the first housing and the second housing are made of aluminum alloy. Aluminum alloy is lightweight, high-strength, and has good heat dissipation properties, which improves the heat dissipation effect of the differential oil and stabilizes its operating performance.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a lightweight integrated differential housing structure, which has the following advantages:

[0017] By setting a bolt seat on the first flange, the connection between the fixing bolt and the first flange is increased, thereby increasing the firmness of the connection between the fixing bolt and the second flange.

[0028] The working principle of this embodiment is as follows:

[0029] By setting a bolt seat 14 on the first flange 13, the connection between the fixing bolt 15 and the first flange 13 is increased, thereby increasing the firmness of the connection between the fixing bolt 15 and the second flange 21. At the same time, a positioning ring 16 is provided on one side of the first flange 13 and is positioned and connected to the positioning groove 22 on the second flange 21, thereby increasing the stability and sealing of the connection between the first flange 13 and the second flange 21.
