[0021] The technical solution of the utility model will be described clearly and completely below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1-3 A front axle housing of an automobile comprises a front axle housing composed of a drive axle housing 1 and a differential housing 11, a mounting seat 2 and a spring seat 3. The combination of the differential housing 11 and the two drive axle housings 1 makes the overall structure more stable. The two drive axle housings 1 are located on the same axis, and the ends of the two drive axle housings 1 that are away from each other are fixedly mounted with flange plates 12, which increases the stability of the structure and facilitates the connection and installation of related components. There are multiple mounting seats 2, which are fixedly mounted on the corresponding drive axle housings 1 for connecting with other parts of the vehicle. A mounting opening is provided on the front side of the differential housing 11, and a connecting seat 111 for connecting to the main reducer differential case is fixedly mounted on the front side of the mounting opening, so that the entire front axle housing can perfectly cooperate with the vehicle's transmission system.

[0023] In this embodiment, there are two spring seats 3, which are fixedly mounted on one side of the corresponding drive axle housing 1 close to the flange plate 12, and are used to install shock-absorbing springs to enhance the driving stability and comfort of the vehicle.

[0024] In this embodiment, the mounting base 2 includes a base and a connecting block 21. A plurality of connecting blocks 21 are fixedly mounted on the drive axle housing 1. A base is fixedly mounted on the side of the connecting block 21 away from the drive axle housing 1, wherein the base includes a connecting column 202, a sealing strip 204, two mounting plates 201 and a plurality of mounting holes 203. The two mounting plates 201 are fixedly mounted with the same connecting column 202 on the side close to each other, wherein one of the mounting plates 201 is fixedly mounted on the connecting block 21, and a plurality of mounting holes 203 are provided on the mounting plate 201 away from the connecting block 21 for connecting with other parts of the vehicle. A sealing strip 204 is clamped on the outer side of the connecting column 202 at a position between the two mounting plates 201. The sealing strip 204 can completely cover the connecting bolts after the connecting bolts are installed, thereby avoiding the erosion of the connecting bolts during actual use.

[0025] In this embodiment, the materials of the drive axle housing 1 and the differential housing 11 are both high-strength steel, which has excellent load-bearing capacity and impact resistance, can effectively support the front structure of the vehicle, and ensure the stability and safety of the vehicle's driving. At the same time, reinforcing ribs that are parallel to the axis of the drive axle housing 1 are fixedly installed on the inner wall of the drive axle housing 1. The reinforcing ribs are fixed to the inner wall of the drive axle housing 1 in an embedded manner, which can further improve its structural strength and load-bearing capacity.

[0026] In this embodiment, the mounting seat 2, flange plate 12 and spring seat 3 are all made of high-strength aluminum alloy, which has sufficient supporting strength and can reduce the weight of the entire front axle housing, thereby improving the fuel economy and driving efficiency of the vehicle.

[0027] In this embodiment, a mounting groove 31 is further provided on the side of the spring seat 3 away from the drive axle housing 1. The design of the mounting groove 31 can facilitate the rapid positioning of the shock-absorbing spring, which can not only improve the convenience of installation, but also improve the accuracy of installation.

[0028] Working principle: The front axle housing is connected to other relevant parts of the vehicle through the mounting seat 2, and then the shock-absorbing spring is installed in the mounting groove 31 of the spring seat 3. Through the design of the mounting groove 31, the shock-absorbing spring can be quickly positioned conveniently, thereby improving the convenience and accuracy of installation. At the same time, since the front axle housing is made of high-strength steel and high-strength aluminum alloy, it has excellent load-bearing capacity and impact resistance, can effectively support the front structure of the vehicle, and ensure the stability and safety of the vehicle's driving. In addition, after the connection is completed, the sealing strip 204 is pressed to the position between the two mounting plates 201, thereby providing a shielding and protective effect for the connecting bolts used for connection, thereby avoiding the erosion of the connecting bolts during actual use and extending the service life of the front axle housing.
