- Abstract
The characteristics and selection application of three typical structures of hub bearing units for commercial vehicles and their selection and application. Traditional wheel hub bearing units are widely used because of their mature manufacturing technology and low cost. Grease lubricated wheel hub bearing units and oil lubricated wheel hub bearing units It has reliable performance and high cost, and is mainly used in high-end commercial vehicles. The influence of bearing clearance on its life and friction torque was studied. The bearing life is longest when the working clearance is slightly negative, and the bearing clearance can be accurately controlled. Provides a solution for selecting wheel hub bearing unit lubricants based on vehicle operating conditions. The impact of poor oil filling, grease filling, press fitting, tightening process, etc. on the bearing life of the wheel hub bearing unit during the installation and application process was analyzed, and a solution of using special equipment for installation was proposed. Finally, it is pointed out that unitization is the development trend of wheel hub bearing unit structures for commercial vehicles in the future.
