Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy wheel technology, and in particular to a high load-bearing aluminum alloy wheel. Background Technology

[0002] Aluminum alloy wheels are currently a core component of automobiles. They are made from high-strength aluminum alloy through processes such as casting and forging. They are lighter than steel wheels of the same size, and the thermal conductivity of aluminum alloy is several times that of steel. The hollow design of the spokes creates natural airflow channels, which can quickly dissipate heat from the brake disc, prevent brake fade, and extend the life of tires and braking systems. The surface can be anodized, brushed, polished, etc., and the design is diverse, enhancing the appearance and texture of the vehicle. They are suitable for various models, including fuel vehicles and new energy vehicles.

[0003] In existing technologies, to ensure heat dissipation, shock absorption, and weight reduction, wheel hubs typically use multiple spokes for support on the inner side. These spokes have gaps between them. When the hub is located inside these gaps and subjected to high-intensity pressure impacts, it cannot effectively distribute the excessive pressure evenly across the supporting spokes, potentially causing deformation and affecting subsequent use. Therefore, this invention designs a high-load-bearing aluminum alloy wheel hub. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the prior art by proposing a high load-bearing aluminum alloy wheel hub.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-load-bearing aluminum alloy wheel hub includes an outer ring, an inner hub, and multiple spokes. The multiple spokes are respectively fixedly arranged around the outer side of the inner hub. The outer ring is respectively fixedly arranged on the side of the multiple spokes facing away from the inner hub. The inner hub has multiple mounting bolts threaded around its interior. The multiple spokes are respectively arc-shaped. A stress-relief strip is fixedly connected to one side of each of the multiple spokes. A steel plate is fixedly connected to one side of each pair of adjacent stress-relief strips. The inner wall of the outer ring of the wheel hub is provided with multiple slots around the corresponding side of the multiple spokes. Load-bearing steel plates are fixedly inserted into the inner wall of the outer ring of the wheel hub in the slots. The load-bearing steel plates are respectively fixedly arranged on the side wall of the steel plate.

[0007] Preferably, a first support strip is fixedly provided on one side of each of the multiple spokes. The first support strip is arc-shaped and has multiple weight-reducing through holes on its inner wall.

[0008] Preferably, a second support bar is fixedly connected to each of the opposite sides of the plurality of spokes, a slot is opened on each of the opposite sides of the plurality of spokes, and a pressure relief block is fixedly connected to each end of the plurality of second support bars, the pressure relief block being clamped and set on the inner wall of the slot.

[0009] Preferably, the steel plate is configured as an arc-shaped plate, and the plurality of load-bearing steel sheets located on the outer side of the outer ring of the wheel hub are respectively configured as arc surfaces.

[0010] Preferably, a reinforcing steel strip is fixedly connected to the inner wall of the first support strip, and the reinforcing steel strip is pressed against the side wall of the steel plate.

[0011] Preferably, the side wall of the pressure relief block has rounded corners, and the spokes are located on the inner wall of the groove and match the pressure relief block.

[0012] Compared with the prior art, this utility model provides a high load-bearing aluminum alloy wheel hub, which has the following beneficial effects:

[0013] 1. This high-load-bearing aluminum alloy wheel hub bears the road pressure and impact force transmitted by the tire through the outer ring of the hub. This force is transmitted to the steel plate through the load-bearing steel plate fixedly inserted into the slot of the inner wall of the outer ring of the hub. The load-bearing steel plate is set with an arc surface and adapted to the outer side of the outer ring of the hub. The steel plate is an arc plate. The combination of the two can evenly distribute the pressure and avoid local stress concentration. The steel plate is fixedly connected to the stress relief strip on the corresponding side of multiple spokes. The stress relief strip further transmits the force to the spokes, realizing multi-level dispersion of pressure and improving the overall load-bearing capacity of the wheel hub.

[0014] 2. This high-load-bearing aluminum alloy wheel hub uses a second support bar fixed to the side opposite to the spokes, which is secured in the spoke groove by pressure relief blocks at both ends. The rounded corners of the pressure relief blocks facilitate the clamping assembly and match the inner wall of the groove, ensuring a firm connection. The second support bar enhances the lateral support force of the spokes, preventing the spokes from deforming under lateral forces. At the same time, it plays a role in pressure relief and buffering when the vehicle is bumpy, further improving the structural stability of the wheel hub. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example 1

[0021] Reference Figure 1-3 A high-load-bearing aluminum alloy wheel hub includes an outer ring 1, an inner hub 2, and multiple spokes 3. The multiple spokes 3 are respectively fixedly arranged around the outer side of the inner hub 2. The outer ring 1 is respectively fixedly arranged on the side of the multiple spokes 3 away from the inner hub 2. Multiple mounting bolts 4 are threaded around the inside of the inner hub 2. The multiple spokes 3 are respectively set in an arc shape. A stress relief strip 5 is fixedly connected to the corresponding side of the multiple spokes 3. A steel plate 10 is fixedly connected to the corresponding side of two adjacent stress relief strips 5. Multiple slots are respectively opened around the inner wall of the outer ring 1 on the corresponding side of the multiple spokes 3. Load-bearing steel plates 11 are respectively fixedly inserted into the inner wall of the outer ring 1 on the multiple slots. The load-bearing steel plates 11 are respectively fixedly arranged on the side wall of the steel plate 10. The steel plate 10 is set in an arc shape. The multiple load-bearing steel plates 11 are respectively set in an arc shape on the outer side of the outer ring 1.

[0022] A first support bar 6 is fixedly provided on one side of each of the multiple spokes 3. The first support bar 6 is arc-shaped and has multiple weight-reducing through holes 7 on its inner wall.

[0023] Multiple spokes 3 are fixedly connected to a second support bar 8 on opposite sides. The opposite sides of multiple spokes 3 are provided with slots. Both ends of multiple second support bars 8 are fixedly connected to a pressure relief block 9. The pressure relief block 9 is clamped in the inner wall of the slot. The side wall of the pressure relief block 9 is provided with rounded corners. The spokes 3 are located in the inner wall of the slot and match the pressure relief block 9.

[0024] The wheel hub has an outer ring 1, an inner hub 2, and multiple spokes 3 as its core load-bearing structure. It is made of aluminum alloy to ensure overall lightweight, while multiple reinforcement structures enhance load-bearing capacity. The inner hub 2 is fixed to the vehicle axle head by multiple threaded mounting bolts 4 to achieve a stable assembly between the wheel hub and the vehicle. Multiple arc-shaped spokes 3 are fixed around the outside of the inner hub 2 and connected to the outer ring 1 to form a stable support frame. The arc structure can distribute the force and improve the bending and impact resistance of the spokes 3.

[0025] During vehicle operation, the outer rim 1 of the wheel hub bears the road pressure and impact force transmitted by the tire. This force is transmitted to the steel plate 10 through the load-bearing steel plate 11 fixedly inserted into the slot on the inner wall of the outer rim 1. The load-bearing steel plate 11 is set as an arc surface and is adapted to the outer side of the outer rim 1. The steel plate 10 is an arc plate. The combination of the two can evenly distribute the pressure and avoid local force concentration. The steel plate 10 is fixedly connected to the stress relief strip 5 on the corresponding side of multiple spokes 3. The stress relief strip 5 further transmits the force to the spokes 3, realizing multi-level dispersion of pressure and improving the overall load-bearing capacity of the wheel hub.

[0026] The first support bar 6, which is fixed on the opposite side of the spoke 3, is also set to be arc-shaped to match the curvature of the spoke 3. The multiple weight-reducing through holes 7 on the inner wall of the first support bar 6 reduce the overall weight of the wheel hub without affecting the load-bearing performance, thus achieving a lightweight design.

[0027] The second support bar 8, which is fixed to the opposite side of the spoke 3, is fastened in the groove of the spoke 3 by the pressure relief blocks 9 at both ends. The rounded corners of the side wall of the pressure relief block 9 facilitate the fastening assembly and match the inner wall of the groove to ensure a firm connection. The second support bar 8 can enhance the lateral support force of the spoke 3, prevent the spoke 3 from deforming under lateral force, and at the same time play a pressure relief and buffering role when the vehicle is bumpy, further improving the structural stability of the wheel hub.

[0028] Through the coordinated efforts of various structures, including arc design, multi-stage force transmission, and reinforced steel components, the wheel hub is made lightweight while significantly improving its load-bearing capacity, deformation resistance, and impact resistance. This ensures the wheel hub is stable and reliable during vehicle operation and is suitable for high-load-bearing applications.

[0029] Example 2

[0030] Reference Figure 1-3 The inner wall of the first support bar 6 is fixedly connected with a reinforcing steel bar 12, which is pressed and set on the side wall of the steel plate 10.

[0031] The reinforcing steel strips 12 on the inner wall of the first support strip 6 are pressed against the side wall of the steel plate 10, which not only enhances the structural strength of the first support strip 6, but also helps to disperse the pressure transmitted by the steel plate 10.
