The steel hub has high strength and is commonly used for large trucks; however, the steel hub has heavy mass and single appearance, is not in line with the current low-carbon and fashionable concepts, and is gradually replaced by the aluminum alloy hub. Compared with steel automobile hubs, aluminum alloy wheel hub's advantage is more obvious: the density is low, about 1/3 in steel, which means that an aluminum alloy hub using the same volume will be 2/3 lighter than a steel hub. Statistics shows that the whole automobile mass is reduced by 10%, and the fuel efficiency can be improved by 6-8%, so that the popularization of the aluminum alloy hub has important significance for energy conservation, emission reduction and low-carbon life.

The structures of the wheel rim and the flange are the same as the embodiment.
Example 4: the hubs of examples 1, 2 and 3 and comparative example 1 were subjected to weight measurement, and the results thereof are shown in table 1.
Table 1: the results of weight measurement (unit: Kg) of examples 1, 2 and 3 and comparative example 1.
As can be seen from Table 1, in the case of the structures of the other portions being identical, the weight of examples 1, 2 and 3 was reduced compared to the comparative example, and the weight of example 1 was reduced by 260g compared to comparative example 1.
Example 5: two performance tests and stress level measurements were performed on the hubs of examples 1, 2 and 3 and comparative example 1. The above wheels were subjected to bending fatigue and radial fatigue tests in accordance with the national standard GB/T5909-. Unless otherwise noted, the radial fatigue testing machine used in the present embodiment is also called a wheel radial fatigue testing machine, and is available from jinan permanent testing industrial equipment limited.
Before the radial fatigue test process, the hub is firstly fixed to the radial fatigue test machine, and then the strain gauge is fixed on the front face of the window of the hub and is connected to the data acquisition device through a lead. Then, the loading and the rotation of the fatigue test are carried out according to the method of the national standard GB/T5909-2009. After at least one wheel revolution, the strain gauge transmits strain information (epsilon, dimensionless, in percent) to the data acquisition device. Then according to the stress-strain relationship: σ = E ∈, converting strain into stress (σ is stress, in MPa; E is the elastic modulus, 68980 MPa). The results of their test passability and stress level are shown in table 2.
In this embodiment, the strain gauge is an elastic strain gauge available from Zhongsheng Industrial Electrical measuring instruments, Inc.
The results of their test passability and stress level are shown in table 2.
Table 2: wheel Performance test and stress level measurement (Unit: MPa) of examples 1, 2 and 3 and comparative example 1
Description of the drawings: in the table, Y indicates that the test was passed, and N indicates that the test was not passed.
As can be seen from Table 2, examples 1, 2 and 3 all passed both tests, and comparative example 1 only passed the bending fatigue test.
As can be seen from table 2, the peak stress levels are lower at the window locations for examples 1, 2 and 3 and higher for comparative example 1. Example 1 the stress was 95.8MPa lower than comparative example 1. It can be seen that the hubs of examples 1-3 achieve a substantial reduction in hub stress and weight through the special arrangement of the window shape. This stress drop was not observed in comparative example 1 having no particular shape.
Example 6: static stiffness measurements were made for the hubs of examples 1, 2 and 3 and comparative example 1. The static stiffness measurements were performed in the test center of the medium-grade kayak corporation for the above wheels according to the method of american wheel engineering association's row standard SAEJ 328. The static stiffness represents the resistance of the wheel to deformation when subjected to static forces, the higher the value, the greater the resistance to deformation, and the higher the reliability of the wheel. The test measurement results are shown in table 3.
Table 3: results of measurement of static rigidity of wheels for examples 1, 2 and 3 and comparative example 1 (unit: kNm/rad)
| Example 1 | Example 2 | Example 3 | Comparative example 1 | |
| Static rigidity | 19715.5 | 19532.8 | 19357.2 | 17561.4 |
As can be seen from table 3, examples 1, 2 and 3 all had higher static stiffness values, and comparative example 1 had lower static stiffness values. It is shown that examples 1, 2 and 3 have higher structural stability and higher reliability under the same external force. Comparative example 1 has a low static stiffness value, poor structural stability and low reliability. As can be seen from example 6, weight reduction and improvement in static rigidity were achieved in the wheels of examples 1 to 3, and stronger mechanical strength was achieved without increasing (or even decreasing) the material.
