Description

Technical Field

[0001] The present invention relates to the technical field of automotive aluminum alloy wheels, and specifically to a high heat dissipation automotive aluminum alloy wheel and its usage method. Background Art

[0002] In modern society, due to the increasing requirements for various aspects of automotive safety, stability, maneuverability, comfort, energy conservation, environmental protection, etc., the usage amount of aluminum alloy parts in automobiles is increasing day by day. As one of the important components in the automotive running system, the wheel is also a security part with relatively high requirements. It not only bears the weight of the vehicle, but also can reflect the appearance of the vehicle. For example;

[0003] The authorized announcement number CN208515285U provides an automotive aluminum alloy wheel, including a wheel core, a spoke plate and a rim. A boss is provided on the rear side of the wheel core, a bearing hole runs through the center of the boss, and the bearing hole runs through to the front side of the wheel core. Mounting holes run through circumferentially on the edge of the boss; several spoke plates are circumferentially arranged on the wheel core, and the outer side of the spoke plate is connected with the rim; a reinforcing rib plate is provided on the rear side of the spoke plate; a connecting ring is provided between the rim and the wheel core, and reinforcing spoke plates are symmetrically arranged on both sides of the connecting ring. One end of a reinforcing spoke plate is fixedly connected with the rim, and the other end of the reinforcing spoke plate is fixedly connected with the wheel core. When the present utility model works, the diamond-shaped spoke plate is beautiful in appearance, and under the action of the diamond-shaped reinforcing rib plate, the stress condition of the spoke plate can be effectively improved and the cost is relatively low. Under the action of the reinforcing spoke plate, the rigidity and strength of the wheel can be further enhanced, significantly improving the rigidity and strength of the automotive aluminum alloy wheel, with a beautiful appearance and a relatively low cost, and significantly improving the service life of the automotive aluminum alloy wheel.

[0004] However, its aluminum alloy wheel does not have a strong heat dissipation and cooling effect during high-speed driving and long-time braking, resulting in a large amount of heat generated during the operation of the wheel and the braking system. If the heat cannot be dissipated in time, it is likely to lead to safety hazards such as a decline in braking performance, tire aging, and even tire blowout;

[0005] At the same time, when its aluminum alloy wheel breaks and needs to be repaired, usually the entire device is replaced, resulting in a significant increase in the maintenance and repair cost of the device and affecting the maintenance and repair efficiency of the device.

[0006] We propose a high heat dissipation automotive aluminum alloy wheel and its usage method to solve the problems mentioned above, that is, it does not have a strong heat dissipation and cooling effect during high-speed driving and long-time braking, resulting in a large amount of heat generated during the operation of the wheel and the braking system. If the heat cannot be dissipated in time, it is likely to lead to safety hazards such as a decline in braking performance, tire aging, and even tire blowout. At the same time, when it breaks and needs to be repaired, usually the entire device is replaced, resulting in a significant increase in the maintenance and repair cost of the device and affecting the maintenance and repair efficiency of the device. Summary of the Invention

[0007] The object of the present invention is to provide an aluminum alloy wheel hub for automobiles with high heat dissipation and its usage method, so as to solve the problems proposed in the above-mentioned background technology that it does not have a strong heat dissipation and cooling effect during high-speed driving and long-time braking, resulting in a large amount of heat generated during the operation of the wheel hub and the braking system. If the heat cannot be dissipated in time, it is likely to lead to safety hazards such as a decline in braking performance, tire aging, and even tire bursting. At the same time, when a break occurs and maintenance is required, usually the entire device is replaced, resulting in a significant increase in the maintenance and repair cost of the device and affecting the maintenance and repair efficiency of the device.

[0008] To achieve the above object, the present invention provides the following technical solution: An aluminum alloy wheel hub for automobiles with high heat dissipation, including: an aluminum alloy wheel hub body, and spokes provided at the front end of the aluminum alloy wheel hub body, and a support frame is connected to the center of the spokes;

[0009] It further includes:

[0010] A groove bottom, which is arranged inside the aluminum alloy wheel hub body, and air guide vanes are arranged inside the groove bottom. An air valve hole is opened on the upper side of the aluminum alloy wheel hub body. A first limiting rod is arranged on the outer side of the spoke, and a connecting groove is opened at the rear side of the first limiting rod. A second limiting rod is connected to the inner side of the spoke, and heat dissipation holes are opened inside the spoke;

[0011] A positioning block, which is installed inside the support frame, and a blocking decorative plate is arranged at the front end of the support frame. A connecting component is arranged at the rear side of the support frame.

[0012] In a possible implementation manner, the connecting component includes a limiting block installed at the rear side of the support frame, and a damper is connected to the lower end of the limiting block. A pressing rod is arranged at the rear side of the limiting block, and a guiding block is arranged in the middle of the pressing rod.

[0013] In a possible implementation manner, the limiting block and the blocking decorative plate are relatively snap-fitted to limit the blocking decorative plate.

[0014] In a possible implementation manner, the pressing rod and the guiding block are relatively slidably arranged, and the guiding blocks are symmetrically arranged about the central axis of the pressing rod in the front and rear directions.

[0015] In a possible implementation manner, the air guide vanes are arranged at equal angles inside the groove bottom.

[0016] In a possible implementation manner, the first limiting rod is relatively thread-fastened to both the spoke and the aluminum alloy wheel hub body, and the first limiting rods are arranged at equal angles on the outer side of the spoke, and the heat dissipation holes are opened at equal angles inside the spoke.

[0017] In a possible implementation, the support frame is relatively engaged with the spoke, and the second limiting rod is relatively threadedly connected to both the spoke and the support frame.

[0018] In a possible implementation, its usage method includes the following steps:

[0019] Step 1: By installing the device at the lower end of the vehicle, ensure that the device is matched and connected to the vehicle's braking system to avoid affecting the running stability of the device due to size mismatch;

[0020] Step 2: Drive the device to rotate outside the vehicle through the vehicle's engine and the vehicle's transmission shaft, so that the device drives the vehicle to displace. At this time, the air guide vanes arranged inside the groove bottom rotate with the aluminum alloy wheel hub body, so that the rotating air guide vanes suck the air outside the device into the device;

[0021] Step 3: At this time, the incoming cold air blows and cools the heat generated by the friction between the tire and the ground and the heat generated when the brake pads brake, avoiding damage to the device and the brake pads due to accumulated high temperature, and providing a stable cooling effect for the device.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: This high-heat-dissipating automotive aluminum alloy wheel hub has a strong heat dissipation and cooling effect during high-speed driving and long-time braking, so that the wheel hub and the braking system are not prone to generate a large amount of heat during operation, enabling the heat to be dissipated in a timely manner, avoiding safety problems such as a decline in braking performance and tire aging. At the same time, when a breakage occurs and maintenance is required, there is no need to replace the entire device, reducing the maintenance and repair cost of the device and improving the maintenance and repair efficiency of the device, and having a better usage effect, as shown in the following content:

[0023] 1. The air outside the device is guided through the air guide vanes and the first limiting rod, so that the cold air outside the device enters the inside of the groove bottom. At this time, the air entering inward cools the heat generated by the friction between the tire and the ground, and at the same time, the high temperature generated by the friction of the brake pads during vehicle braking is quickly cooled by the cold air, avoiding deformation and damage of the brake pads and the device inside the braking system due to the influence of high temperature;

[0024] 2. By loosening the limiting connection of the spoke through the second limiting rod and the first limiting rod, maintenance personnel can conveniently take out the spoke from the front end to disassemble the device, facilitating maintenance personnel to replace and repair the damaged and deformed components, improving the maintenance efficiency of the device, avoiding the need to replace the entire device when the device is damaged, and reducing the maintenance and repair cost of the device;

[0025] The damper cooperates with the pressing rod to push the limiting block to displace and reset upward, so that the limiting block fixes the blocking decorative plate on the right side of the support frame. At this time, the blocking decorative plate protects the front end of the second limiting rod, avoiding the second limiting rod arranged inside the spoke from being collided by external objects and loosening during the rotation and use of the device, and improving the structural stability of the device.

Detailed Embodiment

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection scope of the present invention.

[0034] Please refer to Figure 1-6 , the present invention provides a technical solution: a high-heat-dissipating automotive aluminum alloy wheel hub, including: aluminum alloy wheel hub body 1, groove bottom 2, valve hole 3, connection groove 4, air guide piece 5, spoke 6, first limiting rod 7, second limiting rod 8, heat dissipation hole 9, support frame 10, positioning block 11, blocking decorative plate 12, connection component 13, limiting block 1301, damper 1302, pressing rod 1303 and guiding block 1304.

[0035] Specifically, as Figure 1 , Figure 4 and Figure 6 shown, by installing the device on the outside of the vehicle braking system, and at the same time installing the tire matching the aluminum alloy wheel hub body 1 on the outside of the middle part of the aluminum alloy wheel hub body 1. At this time, the valve core of the tire passes through the valve hole 3 and protrudes out of the front surface of the aluminum alloy wheel hub body 1. The engine of the vehicle drives the device to rotate at the lower end of the vehicle through the vehicle drive shaft, so that the device cooperates with the tire to push the vehicle to move. At this time, the air guide fins 5 arranged inside the groove bottom 2 rotate with the aluminum alloy wheel hub body 1 and the tire. At the same time, the aluminum alloy wheel hub body 1 drives the spokes 6 arranged at its front end to rotate. Since the air guide fins 5 are arranged at equal angles inside the groove bottom 2, the heat dissipation holes 9 opened inside the spokes 6 cooperate with the air guide fins 5 installed inside the groove bottom 2 to guide the air outside the device into the inside of the groove bottom 2. At this time, the air entering inward cools the heat generated by the friction between the tire and the ground. At the same time, when the vehicle brakes, the high temperature generated by the friction of the brake pads is quickly cooled by the blowing of cold air, avoiding the deformation and damage of the brake pads and the device inside the braking system due to the influence of high temperature, facilitating the timely dissipation of the generated heat to the outside, avoiding potential safety hazards such as a decline in braking performance, tire aging, and even tire explosion during the driving of the vehicle, improving the use safety of the device, and extending the service life of the device;

[0036] Specifically, as Figure 2 , Figure 3 and Figure 5As shown, when the device is damaged and needs to be repaired, by rotating the first limiting rod 7 connected to the outside of the spoke 6, at this time, due to the threaded connection relationship between the first limiting rod 7, the spoke 6 and the aluminum alloy wheel hub body 1, the first limiting rod 7 rotating forward disengages from the inside of the spoke 6 and the connecting groove 4, relaxing the series connection of the spoke 6 and the aluminum alloy wheel hub body 1. At the same time, rotate the second limiting rod 8 arranged inside the spoke 6. Due to the threaded connection relationship between the second limiting rod 8, the spoke 6 and the support frame 10, the second limiting rod 8 rotating forward relaxes the limitation of the spoke 6 and the support frame 10, facilitating the operator to pull the spoke 6 arranged at the front end of the aluminum alloy wheel hub body 1 forward, so that the spoke 6 disengages from the inside of the aluminum alloy wheel hub body 1, facilitating the operator to quickly disassemble the device, enabling the operator to conveniently replace and repair the damaged and deformed components, improving the maintenance efficiency of the device, and avoiding the need to replace the entire device when it is damaged. At this time, when it is necessary to repair a single damaged part, the maintenance and repair cost of the device is reduced; after the device is repaired, install the brand-new components back into the device. At this time, repeat rotating the second limiting rod 8 arranged inside the spoke 6 and the first limiting rod 7 connected to the outside of the spoke 6, so that the rotating first limiting rod 7 and second limiting rod 8 fix the spoke 6 to the front end of the aluminum alloy wheel hub body 1 again. At the same time, the operator connects the connecting component 13, and the connecting component 13 includes a limiting block 1301, a damper 1302, a pressing rod 1303 and a guiding block 1304. At this time, the pressing rod 1303 is pressed by the maintenance personnel and displaces downward at the rear side of the support frame 10. Due to the sliding connection relationship between the pressing rod 1303 and the guiding block 1304, the pressing rod 1303 is guided by the guiding block 1304 during the downward displacement. At this time, the displaced pressing rod 1303 pushes the limiting block 1301 connected to its lower side to displace downward and squeeze the damper 1302. At the same time, install the blocking decorative plate 12 along the positioning block 11 arranged inside the support frame 10 at the front end of the support frame 10. At this time, release the pressing on the pressing rod 1303, so that the lower side of the limiting block 1301 rebounds and resets due to being squeezed by the damper 1302, causing the limiting block 1301 to be pushed upward and reset by the damper 1302. Due to the snap-fit connection relationship between the limiting block 1301 and the blocking decorative plate 12, the upward-resetting limiting block 1301 fixes the blocking decorative plate 12 inside the support frame 10. At this time, the blocking decorative plate 12 protects the front end of the second limiting rod 8, avoiding the second limiting rod 8 arranged inside the spoke 6 from being loosened due to being collided by foreign objects during the rotation and use of the device, and improving the structural stability of the device.

[0037] Working principle: When using this high-heat-dissipating automotive aluminum alloy wheel hub, first, install the tire matching the aluminum alloy wheel hub body 1 on the outer side of the middle part of the aluminum alloy wheel hub body 1, so that the tire wraps the device inside it. At this time, the valve core of the tire passes through the valve hole 3 and protrudes from the front surface of the aluminum alloy wheel hub body 1. At the same time, install the tire and the device on the outer side of the vehicle braking system, so that the device cooperates with the tire to support the vehicle;

[0038] Secondly, during the use of the vehicle, the engine of the vehicle drives the device and the tire to rotate at the lower end of the vehicle through the vehicle's transmission shaft, so that the device cooperates with the tire to push the vehicle to move. At this time, the air guide piece 5 arranged inside the groove bottom 2 rotates with the aluminum alloy wheel hub body 1 and the tire. At the same time, the aluminum alloy wheel hub body 1 drives the spokes 6 arranged at its front end to rotate, so that the heat dissipation holes 9 opened inside the spokes 6 cooperate with the air guide piece 5 installed inside the groove bottom 2 to guide the air outside the device into the inside of the groove bottom 2. At this time, the air entering inward blows and cools the frictional high temperature generated during braking, avoiding the high temperature from affecting the use effect of the brake pads;

[0039] At the same time, when the device is damaged and needs to be repaired, take out the device and the tire to the outside of the braking system, and rotate the first limiting rod 7 arranged outside the spoke 6 at the same time. At this time, due to the threaded connection relationship between the first limiting rod 7 and the spoke 6 and the aluminum alloy wheel hub body 1, the first limiting rod 7 rotating forward disengages from the inside of the spoke 6 and the connecting groove 4, relaxing the series connection of the spoke 6 and the aluminum alloy wheel hub body 1. At the same time, rotate the second limiting rod 8 arranged inside the spoke 6. Due to the threaded connection relationship between the second limiting rod 8 and the spoke 6 and the support frame 10, the second limiting rod 8 rotating forward relaxes the limitation of the spoke 6 and the support frame 10, facilitating the operator to pull the spoke 6 arranged at the front end of the aluminum alloy wheel hub body 1 forward, so that the spoke 6 disengages from the inside of the aluminum alloy wheel hub body 1, facilitating the operator to quickly disassemble the device, enabling the operator to conveniently replace and repair the damaged and deformed parts, avoiding the need to replace the entire device when the device is damaged. At this time, when it is necessary to repair a single damaged part, the maintenance and repair cost of the device is reduced;

[0040] Finally, reinstall the replaced rotating spoke 6 at the front end of the aluminum alloy wheel hub body 1. At this time, repeat the second limiting rod 8 provided inside the rotating spoke 6 and the first limiting rod 7 connected to the outside of the spoke 6, so that the rotating first limiting rod 7 and the second limiting rod 8 fix the spoke 6 at the front end of the aluminum alloy wheel hub body 1 repeatedly. At the same time, operate the pressing rod 1303, so that the pressing rod 1303 pushes the limiting block 1301 connected to its lower side to displace downward to squeeze the damper 1302. At the same time, install the blocking decorative plate 12 along the positioning block 11 provided inside the support frame 10 at the front end of the support frame 10. At this time, release the pressing on the pressing rod 1303, so that the limiting block 1301 is pushed by the damper 1302 to reset upward to fix the blocking decorative plate 12 inside the support frame 10, and protect the front end of the second limiting rod 8 through the blocking decorative plate 12, thus completing the assembly and use of the device. This is the usage method of the high-heat-dissipating automotive aluminum alloy wheel hub.
