Description

Technical Field

[0001] The utility model relates to the technical field of wheel hubs, and more particularly to a practical automobile wheel hub. Background Art

[0002] Through reasonable structural design, the wheel hub can more effectively dissipate the heat generated by the friction between the tire and the ground, ensuring that the tire temperature is within the normal range. The wheel hub is designed with the need to prevent scratches and collisions. For example, the edge of the wheel hub adopts a rounded transition design to reduce the area of ​​direct contact with obstacles, thereby reducing the possibility of scratches. In addition, some wheels are also equipped with anti-scratch coatings or protective covers to further enhance the anti-scratch ability.

[0003] Deficiencies in existing technology: Insufficient heat dissipation of wheels will cause the temperature of the tire to rise. High temperature will accelerate the aging process of the tire rubber, making the tire hard and brittle, and reducing its elasticity and wear resistance. Insufficient heat dissipation of the wheel will cause the temperature of the brake pads and brake discs to rise. Continuous high temperature will increase the wear of the brake material, reduce the braking effect, and extend the braking distance. During driving, if the wheel cannot effectively prevent scratches and collisions, once it encounters an obstacle or uneven road, the wheel will be easily damaged or even deformed. The deformed wheel will affect the stability and handling of the vehicle and increase driving risks. Utility Model Content

A first hole 304 is provided on the side of the heat dissipation fin 302, the fourth heat dissipation fin 303, the first heat dissipation fin 3, the second heat dissipation fin 301, the third heat dissipation fin 302 and the fourth heat dissipation fin 303, a second hole 305 is provided on the side of the first heat dissipation fin 3, the second heat dissipation fin 301, the third heat dissipation fin 302 and the fourth heat dissipation fin 303, a third hole 306 is provided on the side of the first heat dissipation fin 3, the second heat dissipation fin 301, the third heat dissipation fin 302 and the fourth heat dissipation fin 303, the inner circle side wall of the first hole 304 is fixedly connected to the third movable bolt 307, the inner circle side wall of the third hole 306 is fixedly connected to the fourth movable bolt 309, and the inner circle side wall of the second hole 305 is movably connected to the first circle movable rod 308 and the second multi-circle movable rod 310, which may be used to further increase the flexibility or stability of the heat dissipation fins.

[0024] Among them, a fixing hole 110 is provided at the top of the fixing base 109, and the inner ring side wall of the fixing hole 110 is threadedly connected with a bolt 111, and the bolt 111 is threadedly connected to the wheel hub frame 201. The bolt 111 is threadedly connected to the fixing hole 110 and fixed to the top of the wheel hub frame 201, and the side of the wheel hub frame 201 is fixedly connected to the wheel hub 2, and the top of the fixing block 1 is fixedly connected to the anti-collision guard ring 202. The top of the anti-collision guard ring 202 is provided with a heat dissipation vent 203, and the top of the wheel hub frame 201 is provided with an oblique vent 204. The heat dissipation vent 203 is opened at a 45-degree angle on the anti-collision guard ring 202, and the oblique vent 204 is opened at a 45-degree angle on the anti-collision guard ring 202. The anti-collision guard ring 202 is the outer protective layer of the wheel hub, which can absorb and disperse the impact force from the road surface and protect the wheel hub and the wheel hub from damage. The design of the two vents, the heat dissipation vent 203 and the oblique vent 204, is intended to accelerate air flow and improve the heat dissipation effect of the wheel hub. The heat dissipation vents 203 are usually opened on the top of the anti-collision retaining ring 202, while the oblique vents 204 are opened on the side of the anti-collision retaining ring 202 to form air convection channels.

[0025] The side surface of the wheel hub 2 is fixedly connected to a first fixed ring rod 205 , and the side surface of the wheel hub carrier 201 is fixedly connected to a second fixed ring rod 206 .

[0026] The first movable ring 207 is fixedly connected to the side surface of the first fixed ring rod 205 , and the second movable ring 208 is fixedly connected to the side surface of the second fixed ring rod 206 .

[0027] Among them, the inner ring side walls of the first heat dissipating fins 3, the second heat dissipating fins 301, the third heat dissipating fins 302 and the fourth heat dissipating fins 303 are fixedly connected to the inner ring side walls of the third movable bolt 307, which are movably connected to the inner ring side walls of the second movable ring 208. The heat dissipating fins are the main components of the hub heat dissipation structure. They improve the heat dissipation effect by increasing the heat dissipation area. The heat dissipating fins are usually made of materials with good thermal conductivity.

[0028] The outer sidewall of the fourth movable bolt 309 to which the inner sidewalls of the first, second, third, and fourth heat dissipating fins 301 , 302 , and 303 are fixedly connected is movably connected to the inner sidewall of the first movable ring 207 .

[0029] The working principle of the present invention is as follows: when the wheel hub encounters a road obstacle (such as a curb, a stone, etc.) during driving, the obstacle will first contact the anti-collision guard ring 202, and the anti-collision guard ring 202 absorbs part of the impact force through its elasticity and structural strength, and transmits the remaining impact force to the fixed block 1 and the elastic buffer system inside it. The first movable bolt 102 and the second movable bolt 103 in the elastic buffer system will move when subjected to the impact force, compressing the first spring 104, the second spring 105 and the third spring 106, thereby absorbing and dispersing the impact force. The first support bolt 107 and the second support bolt 108 play the role of supporting and stabilizing the entire elastic buffer system to ensure that it will not fail when subjected to the impact force. Through this design, the wheel hub can reduce direct contact with road obstacles, thereby reducing the impact. The invention can reduce the risk of damage and maintain the integrity of the wheel hub, ensuring the stability and controllability of the vehicle during driving. When the wheel hub generates heat during driving, the heat will be transferred to the heat dissipation fins through the wheel hub frame 201 and the wheel hub 2. The first hole 304, the second hole 305 and the third hole 306 on the heat dissipation fin increase the heat dissipation area, so that the heat can be dissipated into the air faster. The third movable bolt 307 and the fourth movable bolt 309 are movably connected to the inner ring side walls of the second movable ring 208 and the first movable ring 207 respectively. This design allows the heat dissipation fins to swing with the rotation of the wheel hub, further increasing the heat dissipation effect. At the same time, the design of the heat dissipation vents 203 and the oblique vents 204 also accelerates the air flow, so that the heat can be dissipated faster through air convection.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
