Abstract
Description
Technical Field
[0001] The utility model belongs to the field of wheel hubs, and in particular relates to a heat dissipation type automobile wheel hub. Background Art
[0002] The wheel hub, also called the wheel rim, wheel, or tire bell, is a cylindrical metal part with the inner contour of the tire supporting the tire, and the center is mounted on the shaft. The wheel hub is an important driving component of the car, bearing most of the load generated during the driving process of the car. Therefore, the structure of the wheel hub has a great influence on the performance of the car. The car hub is generally in a high-speed running state, especially in the extreme state, the parts in the wheel hub heat up more seriously. Nowadays, when the wheel is rotating, the outer side of the wheel hub has a larger contact surface with the air, so it dissipates heat faster, while the inner side of the wheel hub is blocked and heated by various parts of the wheel, resulting in poor internal heat dissipation, which leads to serious heating of the parts in the wheel hub, which is prone to car driving accidents. Moreover, most of the heat dissipation wheels now directly change their structure, and their structure cannot be selected, so their application range is small. Utility Model Content
[0003] The utility model aims at solving the deficiencies of the prior art and provides a heat dissipation type automobile wheel hub.
[0004] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a heat dissipation type automobile wheel hub, comprising a wheel hub, the wheel hub is hollow, and at least two support rods are circumferentially arranged in the wheel hub, characterized in that: a groove is formed on the outer end surface of each support rod, and a wind hanging component is arranged in the groove;
[0005] The wind hanging assembly includes a baffle, a cylindrical block is fixed to the end face of the baffle away from the center line of the hub, a ball block is fixed to the end face of the baffle away from the cylindrical block, and the ball block is movably connected in the side end wall of the groove, so that more air can enter the wheel when it rolls.
[0006] Optionally, the baffle is trapezoidal in shape, the cylindrical block is located on the wider side of the baffle, the cylindrical block is located at a side edge of the baffle perpendicular to the support rod, and the cylindrical block is slidably connected to the wheel hub.
[0007] Optionally, an annular swivel cavity is further provided on one end face of the hub, and the swivel cavity is located on the outer peripheral side of the support rod. A swivel is installed in the swivel cavity through a spring, and a connecting pin is movably connected between the swivel and each of the baffles, and the connecting pin is installed on the other side edge of the baffle perpendicular to the support rod.
[0008] Optionally, at least two slots are formed on the inner wall of the swivel cavity on one side away from the support rod, and buckles are provided in the slots, and the buckles are fixed to the swivel.
[0009] In summary, compared with the prior art, the present invention has the following beneficial effects:
[0010] 1. Due to the setting of the wind hanging component, the position of the baffle can be changed, that is, the baffle can be extended obliquely to form the effect of fan blades, so that more air can be scraped and the air can flow into the wheel hub more quickly, which can speed up the cooling effect inside the wheel hub and effectively avoid the parts in the wheel hub from heating up quickly and causing damage.
[0011] 2. Since the baffle can scrape more air, it will cause greater resistance and affect the vehicle speed. Therefore, the baffle can be retracted through the setting of the swivel, and you can freely choose whether you need the fast heat dissipation mode, which increases the diversity of choices.

[0018] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.
[0019] As shown in Figures 1-5, a heat dissipation type automobile wheel hub includes a wheel hub 10, which is hollow inside and has at least two support rods 11 circumferentially distributed inside the wheel hub 10. A groove 12 is formed on the outer end face of each support rod 11, and a wind hanging component is provided in the groove 12. The wind hanging component includes a baffle 13, and a cylindrical block 19 is fixed to the end face of the baffle 13 on the side away from the center line of the wheel hub 10. The baffle 13 is trapezoidal in shape, and the cylindrical block 19 is located on the wider side of the baffle 13. The cylindrical block 19 is located at a side edge of the baffle 13 perpendicular to the support rod 11. The cylindrical block 19 is slidably connected to the wheel hub 10, and a ball block 15 is fixed to the end face of the baffle 13 on the side away from the cylindrical block 19. The ball block 15 is movably connected to the side end wall of the groove 12, so that more air can enter the wheel when it rolls through the baffle 13.
[0020] An annular swivel cavity 18 is also provided on one end face of the hub 10, and the swivel cavity 18 is located on the outer peripheral side of the support rod 11. A swivel 16 is installed in the swivel cavity 18 through a spring, and a connecting pin 14 is movably connected between the swivel 16 and each baffle 13, and the connecting pin 14 is installed at the other side edge of the baffle 13 perpendicular to the support rod 11. At least two slots are also provided on the inner wall of the swivel cavity 18 on the side away from the support rod 11, and a buckle 17 is provided in the slot, and the buckle 17 is fixed to the swivel 16.
[0021] During use, when it is necessary to enhance the cooling of the wheel, it is necessary to first press down the swivel 16, rotate the swivel 16, disengage the buckle 17 from the slot, and then pop out the swivel 16 under the elastic force of the spring. The popping out of the swivel 16 will also connect the latch 14 to drive one side of the baffle 13 to extend, and then continue to rotate the swivel 16 to make the swivel 16 clamp the other side of the slot again. At this time, the cylindrical block 19 is located at the position of the previous connection point of the connecting latch 14, and the connecting latch 14 drives the baffle 13 to extend obliquely. At this time, when the vehicle moves forward, the oblique baffle 13 can be used to make the wheel hub act like a fan blade, which can scrape more air and make the air flow into the wheel more quickly, thereby accelerating the cooling effect of the wheel.
[0022] When not in use and there is no need to enhance the cooling of the wheel, it is necessary to press down the swivel 16 to disengage the buckle 17 from the other side of the slot and rotate the swivel 16 in the opposite direction at the same time. The baffle 13 drives the cylindrical block 19 to reset through the connecting pin 14, and then continue to press down the swivel 16 to compress the spring. At the same time, continue to rotate the swivel 16 to make the buckle 17 clamp one side of the slot. At this time, the baffle 13 gradually retracts into the groove 12 under the restriction of the connecting pin 14.
[0023] Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
