[0029] Various aspects and features of the present disclosure are described herein with reference to the accompanying drawings.
[0030] It is to be understood that various alterations and modifications can be made to the embodiments herein described. Accordingly, the above description should not be viewed as limiting but merely as exemplifying the embodiments. Other modifications within the scope and spirit of the present disclosure will be apparent to those skilled in the art in light of the above description.
[0031] The accompanying drawings incorporated in and forming a part of the specification, illustrate embodiments of the present disclosure and, together with the general description of the present disclosure given above, and the detailed description of the embodiments given below, serve to explain the principles of the present disclosure.
[0032] These and other characteristics of the present disclosure will become apparent from the following description of the preferred forms given, by way of non-limiting example, with reference to the attached drawings.
[0033] It should also be understood that although this disclosure has been described with reference to some specific examples, those skilled in the art can certainly implement many other equivalent forms of this disclosure, which have the features described in the claims and are therefore all within the scope of protection defined herein.
[0034] The above and other aspects, features and advantages of this disclosure will become more apparent when taken in conjunction with the accompanying drawings and in view of the following detailed description.
[0035] Specific embodiments of this disclosure are described thereafter with reference to the accompanying drawings; however, it should be understood that the claimed embodiments are merely examples of this disclosure, which may be implemented in various ways. Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that could obscure this disclosure. Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but merely to serve as the basis and representative basis for the claims to teach those skilled in the art to use this disclosure in a variety of substantially any suitable detailed structures.
[0036] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in still another embodiment,” all of which may refer to one or more of the same or different embodiments according to this disclosure.
[0037] The first embodiment of this disclosure provides a drive axle structure for a vehicle. The drive axle structure can be a front axle structure or a rear axle structure. In this embodiment, the rear axle structure is used as an example for explanation, but this embodiment is also applicable to the front axle structure.
[0038] like Figure 1 As shown, Figure 1 An exploded schematic diagram of a rear axle structure 10 of a vehicle is shown. The rear axle structure 10 is connected to the vehicle's wheels 30. A brake disc 20 can be disposed between the rear axle structure 10 and the wheels 30. The rear axle structure 10 drives the rotation of the wheels 30, and the brake disc 20 brakes the wheels 30. Specifically, the rear axle structure 10 includes at least a rear axle assembly and a center cover assembly, the center cover assembly being disposed on the outer side of the rear axle assembly facing the wheels 30.
[0039] Specifically, the rear axle assembly includes a rear axle housing 1 and a rear axle half-shaft 2. The rear axle half-shaft 2 extends through the rear axle housing 1 and protrudes from the end face of the rear axle housing 1, facing the direction of the tire 30. A flange 3 is provided at the end of the rear axle half-shaft 2 for connecting to the wheel 30. For this purpose, multiple wheel connection holes 31 are provided on the flange 3. The flange 3 is connected to the wheel 30 through the engagement of the wheel connection holes 31 with fasteners such as bolts. Thus, the rotation of the rear axle half-shaft 2 drives the rotation of the flange 3, which in turn drives the rotation of the wheel 30. The center cover assembly is located on the outside of the flange 3 and is rotatably connected to the flange 3.
[0040] Furthermore, considering that the center cover assembly is located on the outside of the flange 3 on the rear axle half-shaft 2, such as Figure 2 and Figure 4 As shown, a logo mounting slot 8 is provided on the outer end face of the center cover assembly. This logo mounting slot 8 can be used to mount, for example, a vehicle identification plate, or other logos. The logo mounting slot 8 can be located, for example, on the outer edge of the center cover assembly. In this way, the vehicle identification plate can rotate relative to the rotation of the center cover assembly.
[0041] Specifically, in Figure 1 Based on and combined Figures 2-4 As shown, the center cover assembly includes a circular base 11, which is disposed opposite to the flange 3. To achieve a rotatable connection between the flange 3 and the center cover assembly, a first mounting hole 12 is provided on the base 11, which is located at the center of the base 11. The center cover assembly can be installed on the outer end face of the flange 3 by means of fasteners such as fixing bolts cooperating with the first mounting hole 12. Bearings or bushings can be provided on the fasteners, so that the center cover assembly can rotate relatively independently without rotating with the flange 3.
[0042] On the other hand, a ball bearing bracket 13 is provided on the base 11, and a second mounting hole 14 is provided on the ball bearing bracket 13. A ball bearing 15 is disposed in the second mounting hole 14, and the ball bearing 15 is accommodated in the second mounting hole 14 and can roll freely. Figure 5 A schematic diagram of the arrangement of the ball bearings 15 is shown, wherein the ball bearings 15 are arranged in a ring on the base 11 through the second mounting hole 14; furthermore, correspondingly, as Figure 10As shown, a ball track 4 is provided on the flange 3, and the position of the ball track 4 corresponds to the position of the ball 15. In this way, when the center cover assembly is installed on the flange 3, the ball 15 can be accommodated and roll in the ball track 4.
[0043] Thus, when the center cover assembly is mounted on the flange 3, the center cover assembly can rotate relative to the flange 3, and the ball bearings 14 on the center cover assembly can roll within the ball bearing tracks 4 on the flange 3, thereby achieving a rotatable connection between the center cover assembly and the flange 3. In this way, by providing the center cover assembly with the ball bearings 15, the center cover assembly can rotate relative to the flange 3, ensuring that it does not rotate with the rear axle half-shaft 2 during vehicle movement.
[0044] Furthermore, in order to ensure that the vehicle identification plate, for example, provided on the center cover assembly not only does not rotate with the rotation of the rear axle half-shaft 2, but also remains stationary relative to the rear axle housing 1, a first permanent magnet and a second permanent magnet can be respectively provided on the rear axle assembly and the center cover assembly. This allows the center cover assembly to remain stationary relative to the rear axle assembly during vehicle operation through magnetic attraction, preventing it from rotating with the rotation of the rear axle half-shaft 2, thereby ensuring that, for example, the vehicle identification plate remains stationary.
[0045] Therefore, such as Figure 1 As shown, a permanent magnet support 5 is provided on the outer side of the rear axle housing 1. This permanent magnet support 5 is annular and can be fitted onto the rear axle half-shaft 2. Figures 6-9 As shown, in one embodiment, the rear axle housing 1 has a rear axle housing flange 1a, and the permanent magnet support 5 can be fitted onto the outer side of the rear axle housing flange 1a. Therefore, as... Figure 7 As shown, a shoulder structure 51 is provided on the end face of the permanent magnet support 5 facing the rear axle housing 1. The shoulder structure 51 matches the shape of the rear axle housing flange 1a, so that, Figure 9 As shown, during installation, after the permanent magnet support 5 is sleeved on the rear axle half shaft 2, the shoulder structure 51 of the permanent magnet support 5 is snapped into the rear axle housing flange 1a by press fitting, so that the permanent magnet support 5 can be fixed on the outside of the rear axle housing flange 1a. The molding process of the permanent magnet support 5 is simple and the installation is convenient.
[0046] Furthermore, a first permanent magnet 6 is disposed on the permanent magnet support 5. The first permanent magnet 6 can be disposed on the permanent magnet support 5 in various ways, such as... Figure 8As shown, for example, a first mounting box 7 can be provided on the permanent magnet support 5. The first mounting box 7 can be provided on the end face of the permanent magnet support 5 facing the wheel 30 by means of welding, etc. Here, the first permanent magnet 6 is provided in the first mounting box 7. The first mounting box 7 is welded to the end face of the permanent magnet support 5 facing the wheel 30 mainly to avoid contact between the first mounting box 7 and the rear axle half shaft 2.
[0047] Furthermore, such as Figure 2 and Figure 3 As shown, a second permanent magnet 9 is provided on the center cover assembly to attract the first permanent magnet 6. The second permanent magnet 9 can be located on the radial inner or radial outer side of the ball bearing bracket 12. For example, a second mounting box 16 can be provided near the outer edge of the base 11, and the second permanent magnet 9 is located in the second mounting box 16. In this way, during the driving of the vehicle, due to the attraction between the first permanent magnet 6 and the second permanent magnet 9, the center cover assembly will not rotate with the rotation of the rear axle half shaft 2, but will remain relatively stationary with the rear axle housing 1. Thus, when the vehicle is driving, the vehicle identification plate installed on the center cover will not rotate and will always remain stationary, so that the brand logo can be clearly identified. The vehicle identification plate is fixed by the attraction between the two permanent magnets. Its working principle is simple, easy to understand and easy to implement.
[0048] Furthermore, such as Figure 10 and Figure 11 As shown, multiple through holes 32 are provided on the flange 3 of the rear axle half shaft 2. The positions of the through holes 32 correspond to the positions of the first permanent magnet 6 and the second permanent magnet 9. For example, the through holes 32 can be arranged in a ring on the flange 3. The through holes 32 can not only enhance the attraction between the first permanent magnet 6 and the second permanent magnet 9, but also reduce weight and cost.
[0049] The second embodiment of this disclosure relates to a vehicle that includes the drive axle structure of the first embodiment described above, wherein the drive axle structure may be a front axle structure and / or a rear axle structure.
[0050] This embodiment of the invention provides a permanent magnet structure on the drive axle housing and the center cover assembly of the drive axle assembly. This ensures that the center cover assembly and the car logo plate mounted on it do not rotate with the rotation of the wheels during vehicle movement and remain stationary. The structure is simple, the manufacturing cost is low, and it does not affect the existing structure. The brand logo can be clearly identified, thereby highlighting the brand value of the car company.
[0051] Although the subject matter has been described using language specific to structural features and / or methodological logic, it should be understood that the subject matter defined in the appended claims is not necessarily limited to the specific features or actions described above. Rather, the specific features and actions described above are merely illustrative examples of implementing the claims.
[0052] The foregoing has provided a detailed description of several embodiments of this disclosure. However, this disclosure is not limited to these specific embodiments. Those skilled in the art can make various variations and modifications based on the concept of this disclosure, and all such variations and modifications should fall within the scope of protection claimed by this disclosure.
