The “HW18709, HW20716 Type Transmission Assembly†independently developed and developed by China National Heavy Duty Truck Group and owned by independent intellectual property rights, was commissioned by the Science and Technology Department of Shandong Province and commissioned by the Science and Technology Bureau of Jinan City to identify new products. The experts gave two new products. Highly praised.
The expert appraisal committee believes that the main box of the product adopts double countershafts, the auxiliary box adopts planetary gear mechanism, the main box double countershaft structure and the auxiliary box planetary gear mechanism are organically combined, and uniform loading is achieved through multi-component floating; the bearing is supported by large span bearings Structure, improve the output shaft support stiffness; set the main and auxiliary box interlocking mechanism to prevent malfunction caused by synchronizer failure; matched power take-off directly from the main box countershaft to ensure that the output rotation is constant and other aspects of innovation. It has the advantages of high reliability, good fuel economy, large transmission torque, and high transmission efficiency, reaching the leading level of domestic similar products.
HW18709, HW20716 transmission assembly product structure design, advanced performance indicators, cost-effective, using a number of new technology, and has declared national invention patents and utility model patents 7. During the development process, the product has strictly complied with national, industry, and corporate standards, completed the necessary bench test and strict tens of thousands of kilometers of road strengthening test, with a high level of quality, performance and quality indicators The technical requirements of the product design task book have been met, and small batches have been put into the market. The excellent power transmission and excellent product quality have been fully recognized by the market and users.
According to reports, China National Heavy Duty Truck Group has now formed a production capacity of transmission assembly. The successful development of two transmission assemblies, HW18709 and HW20716, has further improved the heavy-duty vehicle power transmission product chain of China National Heavy Duty Truck Group and improved the quality control of its leading products. It is understood that the formation of transmission assembly production capacity has enhanced the company's anti-risk capability, and it is more conducive to the reduction of vehicle costs, technical upgrading and quality control are also more convenient, and makes China National Heavy Duty Truck Group has truly formed a complete high-end of our country. Heavy truck gold industry chain.
China Heavy Vehicle Group has accumulated rich experience in R&D and manufacturing in heavy-duty trucks and drive train assemblies. As Steyr's technology introduction has been in place for more than 20 years, China's heavy-duty vehicle market and user use requirements have undergone tremendous changes, and users are increasingly demanding product quality. To meet the needs of users, CNHTC decided to independently develop a power transmission assembly that can adapt to the characteristics of China's roads.
