Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a wear-resistant axle half-shaft sleeve. Background Technology

[0002] Automotive parts refer to the various units that make up a car as a whole, as well as the various basic components, assemblies, and system components that are used for the normal operation, performance realization, functional expansion, or maintenance of the car. They are the basic building blocks of automobile manufacturing, assembly, repair, and upgrading. Wear-resistant axle half-shaft sleeves, as key components on the automotive drive axle assembly, are integrated with the drive axle housing to fix the axial relative positions of the left and right drive wheels, support the frame and the mass of the various assemblies on it, and bear the road reaction force and torque transmitted from the wheels when the car is in motion, which is then transmitted to the frame through the suspension. Wear-resistant sleeves are designed with special materials to effectively reduce wear caused by friction when driving under complex road conditions, improve the service life of parts, and reduce maintenance costs.

[0003] In the existing technology, the connection between the axle sleeve and the axle housing mostly relies on a single interference fit positioning (fixed only by the interference friction between the outer circle of the sleeve and the inner hole of the axle housing). This single positioning method cannot resist the continuous vibration during vehicle operation. After long-term use, the friction of the interference fit surface will gradually decrease, resulting in an assembly gap at the connection between the sleeve and the axle housing, which will destroy the original fitting accuracy. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the single interference fit positioning will cause the connection to loosen after long-term use. To this end, we propose a wear-resistant axle half shaft sleeve.

[0005] To achieve the above objectives, this application adopts the following technical solution: a wear-resistant axle sleeve, comprising a main body of the axle sleeve: a flange is installed at the bottom end of the main body of the axle sleeve, the surface of the flange is provided with a plurality of flange holes, and the upper surface of the outer wall of the main body of the axle sleeve is provided with a groove, the number of the grooves being three and each being provided with an elastic retaining ring, the elastic retaining ring being a C-shaped design.

[0006] Preferably, a rubber plate is mounted on the outer surface of the elastic retaining ring.

[0007] Preferably, the flange has a threaded inspection hole at its top, and a threaded plug is threadedly connected inside the threaded inspection hole. An elastic sealing ring is installed at the bottom of the threaded plug, and a hexagonal groove is formed at the top of the threaded plug.

[0008] Preferably, a resilient bolt sleeve is installed inside the flange hole.

[0009] Preferably, the lower surface of the outer wall of the half-shaft sleeve body is equipped with annular buffer ribs, the number of which is three, and the cross-section of the annular buffer ribs is trapezoidal and integrally formed with the half-shaft sleeve body.

[0010] Preferably, the inner wall of the half-shaft sleeve body is coated with an epoxy resin-based anti-corrosion coating.

[0011] The technical effects and advantages of this utility model are as follows: In this invention, three elastic retaining rings with both interference fit and clamping positioning functions are designed on the surface of the axle sleeve body. When the operator needs to connect the axle sleeve body to the axle housing, the elastic retaining rings and the corresponding structure on the axle housing generate appropriate preload. This preload can effectively eliminate assembly gaps and prevent loosening of the connection due to vibration during vehicle operation. Attached Figure Description

[0014] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following specific embodiments and accompanying drawings are only exemplary descriptions of the technical solution of this utility model, and should not be regarded as the whole of this utility model or as a limitation or restriction on the technical solution of this utility model.

[0015] Reference Figure 1 - Figure 3 As shown, this utility model provides a technical solution: a wear-resistant axle sleeve, including a half-shaft sleeve body 1: a flange 2 is installed at the bottom end of the half-shaft sleeve body 1, a plurality of flange holes 3 are opened on the surface of the flange 2, and a groove 4 is opened on the upper surface of the outer wall of the half-shaft sleeve body 1. There are three grooves 4, and each groove 4 is installed with an elastic retaining ring 5. The elastic retaining ring 5 adopts a C-shaped design. Specifically: When the operator needs to connect the axle sleeve body 1 to the axle housing, simply align the end of the axle sleeve body 1 with the flange 2 with the corresponding installation position on the axle housing, and use bolts or other connectors through the flange hole 3 to securely connect the two. The elastic retaining ring 5 in the slot 4 further assists in fixing and buffering. When the axle sleeve body 1 is assembled with the axle housing, the elastic retaining ring 5, with its C-shaped design, can better fit the corresponding structure on the axle housing, effectively preventing the axle sleeve body 1 from loosening or shaking during use, ensuring the stability and reliability of the overall axle operation. By designing three elastic retaining rings 5 ​​with interference fit and clamping dual positioning functions on the surface of the axle sleeve body 1, when the operator needs to connect the axle sleeve body 1 to the axle housing, the elastic retaining rings 5 ​​generate appropriate preload with the corresponding structure on the axle housing. This preload can effectively eliminate assembly gaps and prevent loosening of the connection due to vibration during vehicle operation.

[0016] Reference Figure 3 As shown in this embodiment: a rubber plate 6 is installed on the outer surface of the elastic retaining ring 5; Specifically: By installing a rubber plate 6 on the outer surface of the elastic retaining ring 5, the rubber plate 6 can play a good role in shock absorption and noise reduction. When the vehicle is in motion, the axle will be subjected to various vibrations and impacts. The rubber plate 6 can absorb some of the vibration energy, reduce the vibration transmission to the half-shaft sleeve body 1 and the entire axle system, and reduce the noise caused by vibration.

[0017] Reference Figure 4 As shown in this embodiment: a threaded inspection hole 7 is provided at the top of the flange 2, a threaded plug 8 is connected to the internal thread of the threaded inspection hole 7, an elastic sealing ring 9 is installed at the bottom of the threaded plug 8, and a hexagonal groove is provided at the top of the threaded plug 8. Specifically: Through the above design, when it is necessary to inspect the interior of the half-shaft sleeve body 1, the operator can use a hex wrench to insert into the hexagonal groove at the top of the threaded plug 8 and easily unscrew the threaded plug 8 from the threaded inspection hole 7, thereby opening the inspection channel; when no inspection is required, the threaded plug 8 is tightly connected to the threaded inspection hole 7 through its internal threads, and the elastic sealing ring 9 at the bottom can play a good sealing role, effectively preventing external dust, moisture and other impurities from entering the interior of the half-shaft sleeve body 1, avoiding problems such as increased wear and corrosion caused by impurities, and further improving the wear resistance and service life of the half-shaft sleeve body 1.

[0018] Reference Figure 4 As shown in this embodiment: an elastic bolt sleeve 10 is installed inside the flange hole 3; Specifically, by designing an elastic bolt sleeve 10 inside the flange hole 3, when the bolt passes through the flange hole 3 and is tightened, the elastic bolt sleeve 10 can undergo appropriate deformation, which can make the connection between the bolt and the flange hole 3 tighter and more stable, reduce bolt loosening caused by vibration and other reasons, and effectively improve installation stability.

[0019] Reference Figure 2 and Figure 5 As shown in this embodiment: annular buffer ribs 11 are installed on the lower surface of the outer wall of the half-shaft sleeve body 1. There are three annular buffer ribs 11. The cross section of the annular buffer ribs 11 is trapezoidal and integrally formed with the half-shaft sleeve body 1. Specifically, by installing three trapezoidal annular buffer ribs 11 on the surface of the half-shaft sleeve body 1, when the half-shaft sleeve body 1 is subjected to external impact or vibration, the annular buffer ribs 11 can effectively disperse and buffer stress by utilizing the structural characteristics of their trapezoidal cross-sections, avoiding local damage caused by stress concentration, thereby enhancing the impact resistance and overall structural stability of the half-shaft sleeve body 1.

[0020] Reference Figure 2 As shown in this embodiment: the inner wall of the half-shaft sleeve body 1 is coated with an epoxy resin-based anti-corrosion coating. Specifically, by applying an epoxy resin-based anti-corrosion coating to the inner wall of the half-shaft sleeve body 1, the inner wall of the half-shaft sleeve body 1 can have stronger corrosion resistance. The epoxy resin-based anti-corrosion coating can effectively isolate moisture, oxygen and other corrosive media from direct contact with the inner wall of the half-shaft sleeve body 1, reduce the probability of chemical corrosion and electrochemical corrosion, thereby extending the service life of the half-shaft sleeve body 1 and ensuring that it can maintain good performance in complex and harsh working environments.

[0021] Working principle: When the operator needs to connect the axle sleeve body 1 to the axle housing, simply align the end of the axle sleeve body 1 with the flange 2 with the corresponding installation position on the axle housing, and use bolts or other connectors through the flange hole 3 to securely connect the two. The elastic retaining ring 5 in the slot 4 further assists in fixing and buffering. When the axle sleeve body 1 is assembled with the axle housing, the elastic retaining ring 5, with its C-shaped design, can better fit the corresponding structure on the axle housing, effectively preventing the axle sleeve body 1 from loosening or shaking during use, and ensuring the overall stability and reliability of the axle operation.

[0022] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
