Description

Technical Field

[0001] This utility model relates to the field of wheel hubs, specifically to an alloy assembled wheel hub. Background Technology

[0002] A wheel hub is a cylindrical metal component that supports the tire from the inside and is mounted on an axle. It is also called a wheel rim, steel rim, wheel, or tire rim. Wheel hubs come in many varieties depending on their diameter, width, molding method, and materials. They are coaxially connected to the drive shaft on the vehicle body, and the drive shaft drives the tire to move, thereby propelling the vehicle.

[0003] Traditional wheel hubs mainly consist of a rim and spokes, which are usually fixedly connected together. This makes the installation and removal of tires from the wheel hub time-consuming and laborious. Authorization announcement number CN219903925U discloses a split wheel hub, which achieves the purpose of detachable connection of the front rim, rear rim, and spokes frame by bolting the front rim to the rear rim, detachably connecting the front rim to the spokes frame, and detachably connecting the spokes frame to the mounting plate. However, its rim and spokes frame are all connected separately by bolts, which requires a large number of bolts. At the same time, the short bolts used result in a large force on the rim during actual use, thus resulting in a large bolt load. Utility Model Content

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] An alloy-assembled wheel hub includes a rim assembly and a spoke assembly. The spoke assembly is fixedly installed on the outer side of the rim assembly. The rim assembly includes an outer rim and an inner rim. The inner side of the outer rim is provided with a first engaging edge, and the inner side of the inner rim is provided with a second engaging edge corresponding to the first engaging edge. The inner wall of the outer rim is provided with a fixing cylinder, and the inner wall of the inner rim is provided with a connecting cylinder corresponding to the fixing cylinder. A fixing bolt passing through the fixing cylinder and the connecting cylinder is movably installed on the outer side of the spoke assembly.

[0006] A further improvement of the present invention is that: the spoke assembly includes a spoke body, a raised edge is provided on the outer side of the spoke body, a slot is provided on the outer side of the outer rim, the raised edge is movably engaged in the inside of the slot, a spoke connecting hole is provided on the outer side of the spoke body, the spoke connecting hole corresponds to the position of the fixing cylinder, and the fixing bolt is movably installed inside the spoke connecting hole.

[0007] A further improvement of this utility model is that the fixed cylinder and the connecting cylinder are distributed in a ring at equal intervals inside the outer rim and the inner rim.

[0008] A further improvement of this utility model is that: the inner and outer sides of the fixed cylinder are provided with insertion holes, and the inner side of the connecting cylinder is fixedly connected with a limiting ring, which is movably engaged inside the insertion hole.

[0009] A further improvement of this utility model is that the slot is arranged in a fan shape to match the convex edge.

[0010] A further improvement of this utility model is that the slot and the protrusion are both distributed in a ring shape.

[0011] A further improvement of the present invention is that: a second limiting ring is provided on the inner side of the spoke body, which corresponds to the position of the spoke connection hole, and the second limiting ring is movably engaged with the inside of the insertion hole.

[0012] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0013] 1. This utility model provides an alloy assembled wheel hub. By using the inner limiting ring on its inner side to lock into the insertion hole on the inner side of the fixing cylinder and engaging with the outer wheel rim through the engagement edge on the inner side of the inner wheel rim, the force at the connection is increased. Then, by locking the spoke assembly on the outer side of the outer wheel rim, and using fixing bolts passing through the spoke assembly, fixing cylinder and connecting cylinder for connection and fixation, the use of short bolts is reduced. Moreover, by using long bolts for fixing, greater tensile and torsional force is provided, which can better resist the influence of external forces and ensure the overall load stability.

[0014] 2. This utility model provides an alloy assembled wheel hub, in which the spoke body uses the convex edge to engage with the corresponding groove, and the setting of the spoke connection hole allows the fixing bolt to pass through to connect and fix the outer wheel rim, inner wheel rim and spoke body, thereby increasing the force between the outer wheel rim and spoke body and improving the stability and load of the connection.

[0021] The present invention will now be described in further detail:

[0022] like Figures 1 to 5 As shown, this utility model provides an alloy assembled wheel hub, including a rim assembly 1 and a spoke assembly 2. The spoke assembly 2 is fixedly installed on the outside of the rim assembly 1. The rim assembly 1 includes an outer rim 11 and an inner rim 12. The inner side of the outer rim 11 is provided with a first engaging edge 13, and the inner side of the inner rim 12 is provided with a second engaging edge 14 corresponding to the first engaging edge 13. The inner wall of the outer rim 11 is provided with a fixing cylinder 15, and the inner wall of the inner rim 12 is provided with a connecting cylinder 16 corresponding to the fixing cylinder 15. The outer side of the spoke assembly 2 is movably installed with a fixing bolt 19 passing through the fixing cylinder 15 and the connecting cylinder 16.

[0023] By using the inner rim 12 to engage with the inner retaining ring 18 corresponding to the insertion hole 17 on the inner side of the fixing cylinder 15 and engaging with the outer rim 11 through the engagement edge 14 on the inner side of the inner rim 12 and the engagement edge 13 on the inner side of the outer rim 11, the force at the connection is increased. Then, by engaging the spoke assembly 2 on the outer side of the outer rim 11, the connection and fixation are achieved by using the fixing bolt 19 passing through the spoke assembly 2, the fixing cylinder 15 and the connecting cylinder 16, thereby reducing the use of short bolts. Furthermore, by using long bolts for the fixing bolt 19, greater tensile and torsional forces are generated, which can better resist the influence of external forces and ensure the overall load stability.

[0024] like Figure 5 As shown, the spoke assembly 2 includes a spoke body 21, a raised edge 22 is provided on the outer side of the spoke body 21, a slot 110 is provided on the outer side of the outer rim 11, the raised edge 22 is movably engaged in the inside of the slot 110, a spoke connecting hole 23 is provided on the outer side of the spoke body 21, the spoke connecting hole 23 corresponds to the position of the fixing cylinder 15, and the fixing bolt 19 is movably installed in the inside of the spoke connecting hole 23.

[0025] The spoke body 21 engages with the groove 110 via the protruding edge 22, and the spoke connection hole 23 allows the fixing bolt 19 to pass through, thus connecting and fixing the outer rim 11, inner rim 12 and spoke body 21. This increases the force between the outer rim 11 and spoke body 21 and improves the stability and load of the connection.

[0026] like Figure 2 and Figure 4 As shown, the fixed cylinder 15 and the connecting cylinder 16 are distributed in a ring at equal intervals inside the outer rim 11 and the inner rim 12.

[0027] The fixed cylinder 15 has insertion holes 17 on both its inner and outer sides. The inner side of the connecting cylinder 16 is fixedly connected to a limiting ring 18, which is movably engaged inside the insertion hole 17.

[0028] The fixed cylinder 15 and the connecting cylinder 16 are arranged in a ring. The limiting ring 18 on the inner side of the connecting cylinder 16 is inserted into the insertion hole 17 to limit the connection between the outer wheel rim 11 and the inner wheel rim 12. This facilitates the connection and reduces the load on the fixing bolt 19 by increasing the force between the outer wheel rim 11 and the inner wheel rim 12, thereby improving the stability of the connection.

[0029] like Figure 5 As shown, the slot 110 is arranged in a fan shape to match the protruding edge 22.

[0030] Both the slot 110 and the raised edge 22 are arranged in a ring shape.

[0031] The fan-shaped slots 110 and the raised edges 22 are arranged in a ring at equal intervals, thereby ensuring the force between the outer rim 11 and the spoke body 21 through the engagement of the slots 110 and the raised edges 22, which helps to improve the stability of the connection.

[0032] like Figure 5 As shown, a limiting ring 24 corresponding to the position of the spoke connection hole 23 is provided on the inner side of the spoke body 21. The limiting ring 24 is movably engaged with the inside of the insertion hole 17.

[0033] The limiting ring 24 is inserted into the insertion hole 17 on the outside of the fixed cylinder 15, which facilitates the docking of the spoke body 21 and the outer rim 11, and at the same time increases the force between the spoke body 21 and the outer rim 11, thus improving the stability of the connection.

[0034] The working principle of this alloy-assembled wheel hub will be explained in detail below.

[0035] like Figures 1 to 5As shown, the inner rim 12 is fitted with a retaining ring 18 on its inner side, which corresponds to the insertion hole 17 on the inner side of the fixing cylinder 15. The inner rim 12 is then engaged with the outer rim 11 by the engagement edge 14 on its inner side. The spoke body 21 is then joined from the outside of the outer rim 11. The outer rim 11 is fitted with a groove 110 on its outer side by the protrusion 22 on its outer side. The protrusion 22 and the spoke connection hole 23 are positioned to correspond to the groove 110 and the fixing cylinder 15, so that the retaining ring 24 on the inner side of the spoke body 21 is engaged in the insertion hole 17 on the outer side of the fixing cylinder 15. Finally, the fixing bolt 19 is inserted through the spoke connection hole 23 into the interior of the fixing cylinder 15 and the connecting cylinder 16. The fixing bolt 19 is then tightened using a tool, thus completing the overall installation and fixing of the rim assembly 1 and the spoke assembly 2.

[0036] The main body of the assembled wheel hub is made of alloy material.

[0037] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
