[0012] In some embodiments, the thickness of the gasket is set between 1.5 mm and 2.5 mm so that the gasket has a certain thickness to prevent relative rotation between the two flanges and the bearing, while also taking into account the low production and use costs, so as to reduce the production cost of the flange assembly.

[0025] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0026] The above and / or additional aspects and advantages of this utility model will become apparent and readily understood from the description of the embodiments taken in conjunction with the following drawings, in which: Figure 1 This is a schematic diagram of the flange assembly according to an embodiment of the present utility model; Figure 2 This is a cross-sectional schematic diagram of a flange assembly according to an embodiment of the present utility model; Figure label: Flange assembly 10, Splined shaft 100, shaft body 110, stepped section 120. Flange 200, Hollow part 210, Bearing 300, Gasket 400, Bushing 500. Detailed Implementation

[0027] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0028] The following is for reference. Figures 1-2 The flange assembly 10 described in this utility model embodiment includes: a spline shaft 100, a flange 200, a bearing 300, and a gasket 400.

[0029] Specifically, flange 200 is sleeved on the outside of spline shaft 100; bearing 300 is sleeved on the outside of spline shaft 100, and in the axial direction, bearing 300 is sandwiched between spline shaft 100 and flange 200; shim 400 is sleeved on the outside of spline shaft 100, and shim 400 is sandwiched between flange 200 and bearing 300.

[0030] It should be noted that during the operation of the transmission device, power is transmitted between the flange 200 and the splined shaft 100. To ensure more accurate power transmission, a bearing 300 is installed between the splined shaft 100 and the flange 200. During this arrangement, the flange 200 and the bearing 300 abut against each other. However, during the use of the flange assembly 10, relative displacement may occur between the flange 200 and the bearing 300, generating frictional noise. This reduces the output performance and user experience of the transmission device, and the noise can be transmitted through the transmission device, further affecting output performance. Therefore, there is a need to provide a transmission device that can prevent relative displacement between the flange 200 and the bearing 300.

[0031] Specifically, this application provides a flange assembly 10, which is adapted to include: a spline shaft 100, a flange 200, a bearing 300, and a gasket 400. The gasket 400 is provided between the flange 200 and the bearing 300. The gasket 400 is adapted to provide friction to reduce the possibility of relative displacement between the flange 200 and the bearing 300, thereby making the power output process of the transmission device more precise and efficient, and improving the performance transmission efficiency of the transmission device.

[0032] According to the embodiment of the present invention, the flange assembly 10 has a gasket 400 between the flange 200 and the bearing 300. The gasket 400 can provide greater friction to avoid relative displacement between the flange 200 and the bearing 300 during transmission, thereby improving the performance transmission effect of the flange assembly 10 and making the flange assembly 10 perform better. At the same time, the elimination of relative friction can avoid noise during use, making the flange assembly 10 quieter and improving the user experience. In addition, the frictional vibration generated during use is eliminated, thereby improving the reliability of the flange assembly 10.

[0033] In some embodiments, the gasket 400 is a Teflon gasket 400. By using Teflon as the gasket material, the gasket 400 gains higher performance due to its high stability, corrosion resistance, high temperature resistance, and wear resistance, thus improving the reliability of the flange assembly 10.

[0034] In some embodiments, the inner diameter of the shim 400 is A, and the outer diameter of the shim 400 is B. The inner diameter A and the outer diameter B satisfy the following relationship: 45mm≤A≤55mm, 55mm≤B≤65mm. That is to say, in the process of setting the shim 400, the influence of the size of the shim 400 on the fit between the flange 200 and the bearing 300 needs to be considered. The size of the inner diameter A is set between 45mm and 55mm so that when the shim 400 is fitted onto the outside of the splined shaft 100, it can be fitted onto the outside more easily, and the fitting process is simpler, thus improving assembly efficiency. The outer diameter B of the gasket 400 should not be too large. If the outer diameter is too large, assembly of the gasket 400 will be inconvenient. If the outer diameter is too small, the contact area between the gasket 400, the bearing 300, and the flange 200 will be relatively small, resulting in lower friction and affecting the transmission stability of the flange assembly 10, potentially causing relative displacement. Therefore, it is suitable to set the inner diameter of the gasket 400 between 45mm and 55mm, and the outer diameter between 55mm and 65mm. In some more specific embodiments, it is suitable to set the inner diameter to 50mm and the outer diameter to 60mm.

[0035] In some embodiments, the thickness of the gasket 400 is C, and the thickness A satisfies the relationship: 1.5mm ≤ C ≤ 2.5mm. Setting the thickness of the gasket 400 between 1.5mm and 2.5mm ensures that the gasket 400 has a sufficient thickness to prevent relative rotation between the two flanges 200 and the bearing 300, while also maintaining low production and usage costs, thereby reducing the production cost of the flange assembly 10.

[0036] In some embodiments, the splined shaft 100 includes a shaft body 110 and a stepped portion 120. The shaft body 110 is disposed on one side of the stepped portion 120. A bearing 300 is sleeved on the outer side of the shaft body 110 and abuts against the connection between the shaft body 110 and the stepped portion 120. A flange 200 is sleeved on the outer side of the shaft body 110. Thus, by adapting the splined shaft 100 to include the shaft body 110 and the stepped portion 120, the shaft body 110 is adapted to allow the flange 200 to be sleeved on the outer side of the shaft body 110, and the bearing 300 is adapted to be engaged between the flange 200 and the stepped portion 120, so that power can be transmitted as designed.

[0037] In some embodiments, the flange 200 has a hollow portion 210, which is sleeved on the outside of the shaft 110. Thus, because the flange 200 has a hollow portion 210, it can be sleeved on the outside of the shaft 110 as designed, thereby better realizing the power process of the flange assembly 10 during use and improving the performance of the flange assembly 10.

[0038] In some embodiments, the hollow portion 210 has an internal spline on its inner peripheral wall and the shaft 110 has an external spline, with the internal spline and external spline being keyed together. That is, by having an internal spline on the inner peripheral wall of the hollow portion 210 and an external spline on the shaft 110, the connection can be made through the spline during the connection process, making the power transmission process more reliable, thereby improving the performance of the flange assembly 10.

[0039] In some embodiments, the flange assembly 10 further includes a bushing 500, which is correspondingly sleeved on the outer side of the bearing 300, and a gasket 400 is disposed inside the bushing 500. That is, during the use of the flange assembly 10, it is suitable to provide a bushing 500 on the outer side of the bearing 300 so that the bushing 500 can provide limiting protection for the bearing 300, thereby greatly enhancing the reliability of the bearing 300. Similarly, the bushing 500 is also suitable for protecting the gasket 400, making the use of the gasket 400 safer.

[0040] The transmission device according to an embodiment of the present invention includes a flange assembly 10 as described above. Because the flange assembly 10 is provided within the transmission device, a shim 400 is provided between the flange 200 and the bearing 300. The shim 400 can provide greater friction to prevent relative displacement between the flange 200 and the bearing 300 during transmission, thereby improving the transmission performance of the flange assembly 10 and enhancing its performance. Simultaneously, the elimination of relative friction prevents noise during use, making the flange assembly 10 quieter and improving the user experience. Furthermore, the frictional vibration generated during use is eliminated, improving the reliability of the transmission device.

[0041] The vehicle according to an embodiment of the present invention includes the transmission device as described above. Therefore, by providing the transmission device as shown above within the vehicle, a shim 400 is provided between the flange 200 and the bearing 300. The shim 400 can provide greater friction to prevent relative displacement between the flange 200 and the bearing 300 during transmission, thereby improving the performance transmission efficiency of the flange assembly 10 and enhancing its performance. Simultaneously, the elimination of relative friction prevents noise during use, making the flange assembly 10 quieter and improving the user experience. Furthermore, the elimination of frictional vibrations generated during use improves the reliability of the transmission device, thereby enhancing the driving experience of the vehicle.
