However, currently existing new energy wheel hubs generally directly use bearings and several steel bars to support them, and the load-bearing and compressive capacities of the wheel hubs are average. When the vehicle is driving, it cannot buffer the collision force well, is easily damaged, which will reduce the service life of the wheel hub and the safety during driving. Utility Model Content

Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0035] As a specific implementation manner, as shown in FIGS. 1 - 3, a wheel hub for a new energy vehicle includes: a wheel hub body 1, and the wheel hub body 1 includes an outer support ring 3;

[0036] An enhancement device is connected to the inner side of the outer support ring 3. The enhancement device includes a first buffer ring 4. A plurality of support bars 5 are spaced apart on the outer wall of the first buffer ring 4. The support bars 5 extend outward to be connected to the inner wall of the outer support ring 3 (the outer support ring 3 and the enhancement device are connected into an integral structure through the support bars 5); Arc-shaped pressure-resistant plates 6 are respectively arranged on both sides of the support bars 5 (the arc-shaped pressure-resistant plates 6 are connected to the support bars 5, and one end of the arc-shaped pressure-resistant plates 6 is connected to the inner wall of the outer support ring 3), and the openings face away from the support bars 5. The other ends of the arc-shaped pressure-resistant plates 6 between two adjacent support bars 5 are connected and integrated;

[0037] A buffer belt 7 is further arranged between the arc-shaped pressure-resistant plates 6 between two adjacent support bars 5, and the buffer belt 7 is integrated with the arc-shaped pressure-resistant plates 6;

[0038] A cavity 8 is arranged below the connection part of the first buffer ring 4 and the support bars 5; An elastic member 9 is vertically arranged in the cavity 8 (that is, the elastic member 9 is arranged inside the first buffer ring 4 (inner cavity), specifically below the connection part of the support bars 5).

[0039] Furthermore, the upper, lower ends and side walls of the elastic member 9 are respectively in contact with the inner wall of the cavity 8.

[0040] As Figure 1 shown, the hub is sleeved inside the rubber tire carcass 2 to form a tire, which is applied to new energy vehicles.

[0041] During the specific use process, as Figure 2 shown, the first buffer ring 4, the support bar 5 connected to the first buffer ring 4, the arc-shaped compression plate 6 connected to the support bar 5, and the buffer belt 7 connected to the arc-shaped compression plate 6 form an integral reinforcement device that is connected to the outer support ring 3 and provides a strong supporting effect on the outer support ring 3.

[0042] During the driving process of new energy vehicles, the setting of the arc-shaped compression plate 6 increases the force-bearing area of the original contact point between the support bar 5 and the outer support ring 3, increasing the compression resistance of the support bar 5 in the vertical direction; realizing the improvement of the hub's pressure-bearing capacity. The setting of the arc-shaped compression plate 6 can further disperse / share a large part of the vertical bearing force, improving the load-bearing and compression resistance of the hub; at the same time, it also largely avoids the problem that the support bar 5 is prone to bending damage when the tire bears a large load, further ensuring the safety during the driving process.

[0043] Furthermore, as Figure 2 、 Figures 4-5 shown, a cavity 8 is provided below the connection of the first buffer ring 4 and the support bar 5 ( Figure 4 ); an elastic member 9 is vertically arranged in the cavity 8 ( Figure 5 ). When the vehicle bears a large load during driving, or when the tire is severely squeezed by an obstacle and then further squeezes the hub, the elastic member 9 (specifically a spring made of steel in this embodiment) can relieve the pressure from the direction of the support bar 5, prevent the first buffer ring 4 from undergoing large damaged deformation, and thus protect the rotating shaft at the center of the tire from damage, ensuring driving safety.

[0044] As a preferred embodiment, the height of the cavity 8 is 1 / 3 - 1 / 2 of the thickness of the first buffer ring 4. At this time, the elastic member 9 accommodated in the cavity 8 can relieve the pressure from the direction of the support bar 5 to the greatest extent, preferably protecting the first buffer ring 4; at the same time, it can also ensure the connection stability between the first buffer ring 4 and the support bar 5.

[0045] As a preferred embodiment, the buffer belt 7 is arranged horizontally in a straight line; the horizontal straight-line arrangement has better resistance, and can better prevent the support bar 5 and the arc-shaped plate connected to the support bar 5 from deforming due to load during long-term driving.

[0046] As a preferred embodiment, the thickness of the middle part of the buffer strip 7 is greater than that of the two ends. In this way, the bending difficulty from the two ends to the middle part gradually increases, making the pressure resistance of the buffer strip 7 stronger and not easily deformed.

[0047] As a preferred embodiment, the support strip 5 extends outward to the outside of the outer support ring 3, and the side wall of the support strip 5 is connected to the outer support ring 3. When the inner wall of the tire receives a large extrusion, the support strip 5 extending to the outside of the outer support ring 3 can relieve the further extrusion of the tire carcass 2 on the outer ring of the wheel hub, improve the overall pressure resistance of the wheel hub, and prevent the overall deformation of the wheel hub.

[0048] Furthermore, the width of the support strip port 10 located outside the outer support ring 3 is greater than the width of the support strip 5. Or the support strip port 10 located outside the outer support ring 3 is arranged in an inverted isosceles trapezoid. In this way, when the tire carcass 2 receives a large extrusion, the contact area between the support strip port 10 extending to the outside of the outer support ring 3 and the inner wall of the tire can be increased, thereby improving the pressure resistance.

[0049] As a preferred embodiment, a protective layer is provided at the support strip port 10 located outside the outer support ring 3. To prevent the support strip port 10 from scraping the inner wall of the tire carcass 2 during extrusion contact, and further protect the inner wall of the tire carcass 2. In this embodiment, the material of the protective layer is the same as that of the tire.

The same or similar parts among the embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.

[0051] The above description is only for the embodiments of the present application and is not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the scope of the claims of the present application.
