Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are only a few embodiments of the invention, and are not exhaustive. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without any creative effort, shall fall within the protection scope of the present invention.

The hub shown in fig. 1 comprises a rim 1 and a web 2 connected with the rim 1, for example, the web 2 is arranged in an integrated manner, a shaft hole 3 is arranged in the central area of the web 2, the shaft hole 3 is used for connecting the hub with a wheel axle, mounting holes 4 are arranged on the web 2 at intervals adjacent to the shaft hole, and the mounting holes 4 are used for fixing the hub with an automobile, which is the prior art and will not be described again;

the wheel disc 2 is provided with first holes 5 at intervals close to the wheel rim 1, the first holes 5 are used for heat dissipation of the wheel hub, and an inflating valve 6 is installed in any one of the first holes 5. The temperature in the hub is reduced by providing first holes 5 spaced apart in the web 2 for heat dissipation. The automobile wheel hub is very hot and is a common phenomenon, but, along with the time of traveling, the air in the tire is caused by the heat generated by extrusion, but if the temperature is too high, the tire is easy to burst, the potential safety hazard exists, and the influence of the ambient temperature is also received, so that the heat in the tire can be effectively discharged through the first hole designed by the scheme, and the potential safety hazard is avoided.

The mounting holes 4 and the first holes 5 are arranged in a staggered mode, and the included angle between the first holes 5 and the mounting holes 4 is 10-36 degrees. The structure greatly avoids the problems of thicker material, larger weight and poorer fuel economy of the whole vehicle in the wheel spoke structure in the prior art, so that the material consumption of the wheel hub spoke is less, the good radiating effect is further improved, the whole radiating effect is uniform, in addition, the air inlet amount of the first hole can be increased through the angle setting of 10-36 degrees, the larger the air inlet amount is, the larger the heat value in the wheel hub taken away by the air exhaust is, and the whole radiating performance of the wheel hub is improved through the air inlet and exhaust in the wheel hub.

As an alternative embodiment, the offset angle between the mounting holes 4 and the first holes 5 is half of the angle between the first holes 5 or the mounting holes 4, in this case, the preferred angle is designed to be 36 ° between the first holes 5, 36 ° between the mounting holes 4, and 18 ° between the first holes 5 and the mounting holes 4, in the best technical solution, the applicant has found in long-term experiments that the angle is set so that the air intake and exhaust amount in the hub are close to each other, and the whole can be understood as the same air intake and exhaust amount, so that in the structural setting where the air intake amount is maximized, the air exhaust amount can maximally take away the heat in the hub, and the same number is set for the number of the first holes 5 and the mounting holes 4, for example, the number of the first holes 5 and the mounting holes 4 of a home-type vehicle or a light-type vehicle is 4, and the number of a medium-type vehicle is generally 6 or 8, the general quantity of commercial car or heavy-duty car is 10, and the angle that staggers of first hole 5 and mounting hole 4 is 18 structure settings, under the circumstances of guaranteeing wheel hub bearing capacity, can reduce the wall thickness around air cock 7, practices thrift wheel hub's consumptive material.

Further, as shown in fig. 2, the spoke plate 2 includes a spoke 21 and a wheel disc 22 integrated with the spoke, the first hole is formed in the spoke 21, for example, the first holes 5 are formed in the spoke 21 at equal intervals, the mounting hole 4 is formed in the wheel disc 22, for example, the mounting hole 4 is formed in the wheel disc 22 at equal intervals, and therefore the effect of the spoke plate can meet the requirement of attractiveness and ensure the overall bearing capacity of the hub. The structure setting of rim plate 22 evagination in spoke 21 increases the area of contact of rim plate 22 and axletree, improves the fastening force of the whole and car axle of wheel hub.

As an alternative embodiment, the rim 1 is provided with rims on both sides, and the joint of the rims and the spoke plates 2 is provided with a groove 7, so that the tire can be conveniently installed on the rim.

Further, air cock 7's mounting means, as shown in fig. 3 and 4, air cock 7 is installed in arbitrary first hole 5, air cock 7 is 120 with rim 1's circumference contained angle, but the setting of this angle slightly increases wall thickness on every side of air cock 7 and is thicker, for example, prior art wall thickness is 3mm, and this technical scheme can improve the wall thickness to 3.5-4mm, improve overall structure's stability, and set up air cock 7 in first hole 5, can ensure that the holistic difficult fracture of wheel hub, and be 120 with air cock 7 and rim 1's circumference contained angle, can effectively ensure the difficult gas leakage of tire.

Another aspect provides an automobile including some or all of the above wheel hub.

Mandatory national standards of external dimensions, axle loads and quality limits of automobiles, trailers and automobile trains (GB1589-2016) revised by the national institute of automotive standards Commission and information organization are officially approved and released by the quality control Bureau and the national standards Commission at 26 months 7 in 2016. The standard specifies the current dimensions and mass of cars, trailers and trains, is applicable to all vehicles used on roads, and is one of the most basic technical standards in the automotive industry. The aim of changing light weight vehicle models is to realize the maximization of loaded goods and improve the transportation efficiency under the condition that the total weight of the vehicle and the goods is not exceeded.

The wheel hub of present case adopts forging magnalium wheel hub, forges magnalium wheel hub and has lighter half weight than the steel ring, because automobile body weight has alleviateed, the higher speed can be produced to the power of engine output, and the vehicle has better nature controlled, and the acceleration performance of starting is better, and braking distance during the brake also can corresponding shortening. The magnesium-aluminum alloy wheel hub has no bubble inclusion and good heat dissipation, the weight of the vehicle is reduced, and the fuel quantity is also reduced.

While the invention has been described with reference to specific embodiments, the invention is not limited thereto, and any person skilled in the art can easily conceive of changes and substitutions within the technical scope of the invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
