[0004] However, the differential housing has a limited ability to bear external impact. When subjected to external impact, the differential housing is easily damaged due to the poor bearing capacity of the differential housing. Therefore, we propose a differential housing with a notch structure at the extended end. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of the present invention are:
[0015] 1. By adding a buffer lining to the outer spherical surface of the gear cover and then setting an elastic buffer shell on the outside of the buffer lining, the elastic buffer shell generates elastic deformation when subjected to force, and the elastic deformation of the buffer lining when subjected to force can effectively offset external impacts, thereby effectively reducing the risk of the gear cover being directly subjected to external impacts, effectively improving the bearing capacity of the differential case when subjected to external impacts, and thus extending the service life of the product;
[0016] 2. By setting buffer ridges on the outside of the elastic buffer shell, the buffering capacity is further improved;

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] As mentioned in the background art, in order to solve the problem that the differential housing in the prior art is not strong enough to withstand external impact, the present invention proposes a differential housing with a notch structure at the extended end.
[0024] Example 1
[0025] Reference Figures 1 to 2 The differential housing with a notched structure at the extended end includes a fixed plate 1, a gear cover 2 integrally formed on the fixed plate 1, an extended end 1 3 provided at one end of the gear cover 2, an extended end 2 4 provided at the other end of the gear cover 2, and a notch 5 provided on both the extended end 1 3 and the extended end 2 4. The above are all technologies disclosed in Publication No. CN216951532U;
[0026] Both sides of the gear cover 2 are fitted with a rubber buffer liner 6, and the outer sides of the buffer liner 6 on both sides are provided with an elastic buffer shell 8. The bottom of the outer wall of the elastic buffer shell 8 on both sides is provided with a screw 7 connected to the fixing plate 1 for fixing the bottom of the elastic buffer shell 8;
[0027] The tops of the outer walls of the elastic buffer shells 8 on both sides are connected to the connecting components to fix the tops of the elastic buffer shells 8, thereby improving the stability of the elastic buffer shells 8 after installation.
[0028] The connecting assembly includes two mounting plates 10, which are respectively arranged on the outside of the elastic buffer shell 8 on both sides. A movable rod 11 is horizontally passed through the two mounting plates 10, and movable plates 12 are provided at both ends of the movable rod 11. The movable plates 12 are provided with buffer springs 13 connected to the mounting plates 10. In order to connect the two movable plates 12 on the opposite sides together, a fixing sleeve 14 is provided on the movable plate 12 on one side, and an insert block 15 inserted into the fixing sleeve 14 is provided on the movable plate 12 on the other side, and a screw 16 connected to the insert block 15 is provided on the fixing sleeve 14.
[0029] A rubber-made buffer ridge 9 is provided on the outer side of the elastic buffer shell 8 .
[0030] The gear cover 2 is provided with a load-reducing through hole, a shaft through hole and a pin recess. This is the technology disclosed in publication number CN216951532U, and the buffer lining 6, elastic buffer shell 8 and buffer ridge 9 in this article all avoid the above structure.
[0031] Example 2
[0032] Reference Figure 1 and Figure 3 The bottom of the elastic buffer shell 8 is evenly provided with positioning protrusions, and the top of the fixed plate 1 is provided with positioning holes 17 for the positioning protrusions to be inserted, so as to facilitate the installation of the elastic buffer shell 8.
[0033] The rest of the structure is the same as that of Example 1.
[0034] When subjected to external impact, it can first be buffered by the buffer ridge 9, then by the elastic buffer shell 8, and finally by the buffer lining 6 to protect the gear cover 2. When the elastic buffer shell 8 on one side is squeezed, the mounting plate 10 on the elastic buffer shell 8 follows the movement, which will squeeze the buffer spring 13 connected to the mounting plate 10, and can also follow the movement through the plug 15, the fixing sleeve 14 and the screw 16 to squeeze the buffer spring 13 on the mounting plate 10 on the other side to improve the buffering capacity of the elastic buffer shell 8. Therefore, the differential case can not only pave the way for configuring a clamping structure on the output shaft to prevent the wheels from slipping, but also improve the ability of the gear cover 2 to withstand external impacts and extend its service life.
[0035] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
