半挂车空气悬挂轴距调节机构优化设计

Optimal design of axle distance regulating mechanism for semi-trailer air suspension

针对目前市场上空气悬架轴距调节机构调节部件和螺栓轴之间接触面积小,调节部件和螺栓轴容易磨损,若不及时维修更换会造成车辆吃胎、甚至发生交通事故等问题,对轴距调节机构进行结构优化设计。通过增加相关零部件间的接触面积,降低零件间的磨损,并结合SolidworksSimulation对优化前后的结构进行仿真对比,验证了优化方案的可靠性。

The small contact area between the regulating part of the air suspension wheelbase regulating mechanism and the bolt shaft on the market at present, the regulating part and the bolt shaft are easy to wear out. If not repaired and replaced in time, the tires will partially wear rapidly which may even cause dangerous traffic accidents, etc. In view of these problems, the structure optimization design of the wheelbase regulating mechanism is carried out. By increasing the contact area between related parts and reducing the wear between parts, and combining with Solidworks Simulation, the structure before and after optimization is simulated and compared to verify the reliability of the optimization scheme.
