Technical Field

[0001] This utility model relates to the field of automotive parts, and in particular to a rear wheel axle core for automotive chassis. Background Technology

[0002] With the rise of the automobile manufacturing industry, rear wheel spindle assemblies are widely used. A rear wheel spindle assembly mainly consists of the rear wheel spindle, bolts, and bearings. The rear wheel spindle assembly houses brake calipers, brake discs, mudguards, and wheel hubs, making it a crucial and indispensable component that receives considerable attention in both production and use.

[0003] For example, the Chinese utility model patent CN215171474U discloses a rear wheel spindle for an automobile chassis with threaded holes for dust cover mounting. By adding countersunk holes, it can effectively avoid the unthreaded parts of the screw, allowing the screw end face to fit snugly against the dust cover. However, such a structure still has the following significant drawbacks:

[0004] 1. Its mounting holes are difficult to adapt to different hole spacings, which means that workers need to frequently change the mounting plate or perform additional processing during installation. This is not only cumbersome and time-consuming, but also seriously restricts the versatility of the device.

[0005] 2. Since the shaft generates heat when it rotates, and the existing shaft has poor natural heat dissipation conditions and a relatively high temperature rise, if it is not controlled, the resulting thermal deformation will seriously reduce the rotation performance and service life of the shaft.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0028] The following description, in conjunction with the accompanying drawings, details a rear wheel axle core for an automobile chassis provided in this application through specific embodiments and application scenarios.

[0029] Example 1:

[0030] like Figures 1 to 4 As shown in the figure, this application embodiment provides a rear wheel axle core for an automobile chassis, including an axle body 1, a mounting base 2, and a mounting hole 3; the mounting base 2 is provided with a sliding groove 21 and a slider 22 that slides in cooperation with the sliding groove 21, the sliding groove 21 is provided with a limiting block 23, the slider 22 is provided with a limiting groove 24 that slides in cooperation with the limiting block 23, the slider 22 is provided with a mounting hole 3, and the mounting base 2 is provided with a locking structure 25 for fixing the position of the slider 22.

[0031] Furthermore, the mounting hole 3 is a straight slot hole perpendicular to the sliding direction of the slider 22.

[0032] Furthermore, the locking structure 25 includes a positioning hole 251 and a positioning groove 252. The slider 22 is provided with a pair of positioning holes 251, and the limiting block 23 is provided with a positioning groove 252 corresponding to the positioning hole 251. The positioning groove 252 is parallel to the sliding direction of the slider 22.

[0033] Furthermore, the slider 22 is provided with anti-slip texture 26.

[0034] In this embodiment of the application, due to the above-described structure, a shaft 1 is fixedly provided on the mounting plate. When it is necessary to adjust the position of the mounting hole 3, the slider 22 is pushed to slide along the slide groove 21. Within a certain range, the mounting hole 3 can be precisely adjusted along the length direction of the mounting base 2. At this time, the bolt is passed through the positioning hole 251 and the corresponding positioning straight groove 252 and fixed with a nut. Subsequently, since the mounting hole 3 is a straight groove hole perpendicular to the sliding direction of the slider 22, the corresponding bolt can be precisely adjusted along the width direction of the mounting base 2 within a certain range, so that the bolt is inserted into the opening of the mounting hole 3 and the external connection part and fixed with a nut.

[0035] The slider 22 is provided with anti-slip texture 26. The anti-slip texture 26 increases the contact friction between the surface of the slider 22 and the hand, especially when the hand is wet, oily or sweaty, it can effectively prevent relative sliding between the hand and the slider 22.

[0036] Example 2:

[0037] like Figure 5 and Figure 6 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the shaft 1 is provided with a U-shaped cooling channel 11, and the mounting base 2 is provided with a circulating liquid inlet 27 and a circulating liquid outlet 28, which are respectively connected to both ends of the U-shaped cooling channel 11.

[0038] Furthermore, the shaft 1 can be divided into an upper shaft 12 and a lower shaft 13. The upper shaft 12 is provided with a U-shaped channel, and the lower shaft 13 is provided with a pair of parallel I-shaped channels. The U-shaped channel and the pair of parallel I-shaped channels can form a U-shaped cooling channel 11. The upper shaft 12 and the lower shaft 13 are fixedly connected by screws.

[0039] Furthermore, the upper shaft 12 is provided with an annular mounting groove 14, and a sealing ring 15 is installed in the annular mounting groove 14. The outer ring of the sealing ring 15 is press-fitted with the lower shaft 13 to form a seal.

[0040] Furthermore, the upper shaft 12 is provided with an alignment block 16, and the lower shaft 13 is provided with an alignment groove 17 that slides with the alignment block 16.

[0041] In this embodiment of the application, due to the above-mentioned structure, the mounting base 2 is provided with a circulating liquid inlet 27 and a circulating liquid outlet 28. The circulating liquid inlet 27 and the circulating liquid outlet 28 are respectively connected to the external cooling pipe. When the external temperature detection sensor detects that the temperature of the shaft 1 is too high, the external control system will automatically introduce cooling water. The cooling water enters the U-shaped cooling channel 11. During the flow of the cooling water in the U-shaped cooling channel 11, it can carry away the heat of the shaft 1, thereby achieving the purpose of cooling down.

[0042] The shaft 1 can be divided into an upper shaft 12 and a lower shaft 13. The upper shaft 12 and the lower shaft 13 are fixedly connected by screws, which makes it easy to disassemble them, so that personnel can easily clean the scale inside and prevent scale from adhering inside the pipe for a long time and affecting the efficiency of heat exchange.

[0043] The upper shaft 12 is provided with an annular mounting groove 14, and a sealing ring 15 is installed in the annular mounting groove 14. The outer ring of the sealing ring 15 is press-fitted with the lower shaft 13 to form a seal. The sealing ring 15 can ensure a good sealing connection between the upper shaft 12 and the lower shaft 13.

[0044] The upper shaft 12 is provided with an alignment block 16, and the lower shaft 13 is provided with an alignment groove 17 that slides with the alignment block 16. During the installation process, the alignment block 16 is aligned with the alignment groove 17, and then the upper shaft 12 is inserted into the lower shaft 13. At this time, the threaded groove on the upper shaft 12 is aligned with the threaded groove on the lower shaft 13, and the U-shaped channel is aligned with a pair of parallel I-shaped channels.
