The paper gives detailed description of the improved design for wet drive axle used in motor grader of Sichuan Chengdu Chenggong . Construction Machinery Co., Ltd.. By comparing with the motor graders produced by various manufacturers, and the analysis the market situation of wet drive axle improves the necessity and imminence for development of wet drive axle. By designing and calculating for the key parts and components in the wet drive axle ensures the reliability for wet drive axle. By comparing and improving of parts and components improves further the product, and increases the performers, and completes the development of wet drive axle.The following fruits can be concluded by research the project: 1. The development for wet drive axle is necessary. From the early period of 90', the drive axle with oil immerged brake begins to be used in the wheel loaders abroad, and later it also be used in the motor grader and other construction machinery. In domestic manufacturing trade, our Co. is the first one to independently develop the wet drive axle. The wet drive axle has large potential in the market. At present, other manufactures have already known the importance of development the wet drive axle, and began to develop it. Our Co. leads up to develop the series of wetdrive axle based on the previous matured experience, and had a good foundation for enterprises in the competition.2. The wet drive axle has dominance in market completion. Now, the domestic wet drive axle is still seldom. Its considerable cost and the large market potentials and profit prove that the wet drive axle is the substitute of the dry drive axle, the sign of the advanced axle.3. The wet drive axle is reliable and wide applications. By calculating the key parts and components of the wet drive axle, such as driving and driven bevel gears, and the structure improvement of drive half axle, choosing the brake, using NO SPIN differential and so on all prove the reliability of the wet drive axle. The use of wet drive axle in wheel loader, motor grader and road roller indicates the wide applications.4. The research of the project meets the target, and has guide meaning to the concerned design and development. |
