Steering wheel 

Cars, boats, aircraft and other manipulation of the direction of travel of the wheel-like device. Fifties, with no steering wheel concept cars have come out, but the consumer is not interested in this car. Because there is no steering wheel of the car simply can not become a car.

Steering wheel manufacturing process of magnesium alloy die-casting 

   First, the historical background of the rapid development of automobile industry, the car faster and faster, more beautiful appearance, interior decoration increasingly complex and diverse, the inherent technological content increasing. Steering wheel also had no small change. Magnesium alloy is the lightest metal structural materials, with the advantages of high strength, superior damping, shock absorption and noise performance, casting forming, machining and surface decoration good performance, easy recycling ratio. Magnesium alloy is applied to the steering wheel can reduce the weight, but also reduce road vibration and control systems, while at the same time an accident occurs, the magnesium alloy wheel can absorb more energy, to ensure driver safety, it has a low carbon steel, plastics and other traditional steering wheel unmatched performance advantages. Therefore, the use of magnesium alloys to replace other traditional materials as steel, aluminum and other manufacturing automobile steering wheel skeleton, will be an inevitable trend. 

  Second, the technical solutions 1. Alloying materials used in aluminum as main alloying elements, with the reduction of aluminum content, the toughness of the alloy increased, therefore, low aluminum magnesium alloy type AM series more suitable for steering and other safety components. However, with the lower aluminum content, to some extent reduce the casting of the alloy, therefore, in the choice of the alloy to achieve the desired mechanical properties, should ensure a high aluminum content in order to ensure its casting, therefore, the choice of AM60 has high strength and good toughness properties at the same time have some casting material as the steering wheel. According to data from the analysis of online search, the series good mechanical properties of magnesium alloy, the elastic modulus E can reach 45 GPa, Poisson's ratio ε of 0.35, tensile strength σb ≥ 200MPa, yield strength σs ≥ 130MPa, elongation δ ≥ 6% (50mm gauge). In weight than traditional iron, aluminum materials reduce more than 30%; process passing rate of the magnesium alloy and aluminum alloy wheel steering equivalent to more than 85%; performance in full compliance with the requirements of the steering wheel. 

In model design and manufacturing processes of the steering wheel is mainly exposed to alternating stress generated due to reverse. The steering wheel mechanical testing standards, should be greater than the static torsional moment of destruction 300 N · m, steering wheel body structure should be based on the finite element analysis was re-designed steering wheel data model based on the three-dimensional structure. Casting process with high pressure and high speed filling characteristics that can be die-casting thin wall castings with complex shapes and also die-casting inserts, very small holes and threaded high strength and surface hardness of the die casting, the production of magnesium alloy components effective way. For the overall structure of the wheel, combined with a magnesium alloy body material fatigue properties are very sensitive to defects in internal characteristics of the material forming the structure of the new process factors were analyzed to obtain the casting to ensure the optimum quality of the structure, while the structure for optimum performance and parameter combination technology to meet the needs of members of the intrinsic quality of castings and related fatigue properties for the realization of the production of new materials to lay the foundation in the rational use of the steering wheel. In response to these conditions, according to the casting process 

Requirements, preliminary design of the steering wheel casting mold casting system. Magnesium alloy die-casting technologies include magnesium alloy melting and protection, die design, process control, subsequent heat treatment, such as load-bearing parts. Numerical simulation software for the design of casting process simulation programs die casting process, through the analysis of the process of filling, solidification and casting defects die casting process, casting further optimize steering, exhaust system and overflow process parameters. The final program for the production of high quality casting wheel provides an important reference. Can take advantage of the existing ordinary cold chamber die casting machine production of magnesium alloy die castings. When filling temperature of 700 ℃, die casting mold temperature of 220 ℃, punch a speed of 2. 34 m / s, to obtain the desired steering wheel skeleton. Calculated in accordance with the results of the test process optimization and production of a qualified AM60 magnesium alloy steering wheel skeleton. Using universal testing machine fatigue and mechanical properties of the steering wheel skeleton. The results showed that the fatigue life of the average reached 11 million times the tensile strength of 220 MPa, elongation rate of 5%. 4 trial and performance tests in accordance with magnesium alloy steering wheel skeleton simulation results Flow23D, using an optimized process parameters on 8 000 kN die casting machines were pre-production on the steering wheel, get qualified products. For the production of AM60 magnesium alloy steering wheel skeleton on universal tester fatigue performance test. When testing the wheel center is fixed in the vertical direction of the rim at the ± 250 kN force is repeatedly applied until the wheel breakage, which is measured by the number of cycles in the fatigue life of the steering wheel skeleton. Fatigue life of the steering wheel skeleton produced an average of 110,000 times, the fracture location shown in Figure 4, and the corporate standard is 10 million times, indicating fatigue performance steering wheel skeleton has reached the business requirements.
