China National Heavy Duty Truck Group recently launched two new transmission assembly products

Xinhua News Agency, Jinan, December 7th (Reporter Lu Fuming) HW18709 and HW20716 two kinds of transmission assemblies independently developed by China National Heavy Duty Truck Group and possessing independent intellectual property rights. Recently, they were commissioned by the Science and Technology Bureau of Shandong Province to organize new projects organized by Jinan Science and Technology Bureau. Product identification.
The expert appraisal committee composed of experts from Harbin Institute of Technology, Shandong University, Qingdao University, Shandong Jiaotong University, Shandong Automobile Industry Association and Shandong Automobile Engineering Society believes that the main box of this product adopts double auxiliary shafts, and the auxiliary box adopts planetary gear mechanism. The main shaft double auxiliary shaft structure and the auxiliary box planetary gear mechanism are organically combined, and the load is realized by multi-component floating; the large-span bearing support structure is adopted to improve the output shaft support rigidity; the main and auxiliary box interlocking mechanism is set to prevent misoperation The synchronizer fails; the matched power take-off is driven directly by the main box countershaft, ensuring that the output rotation direction is unchanged. The utility model has the advantages of high reliability, good fuel economy, large transmission torque and high transmission efficiency, and reaches the leading level of domestic similar products.
It is understood that HW18709, HW20716 transmission assembly products have adopted a number of new processes, and have applied for 7 national invention patents and utility model patents. China National Heavy Duty Truck Group has formed a mass production capacity of the transmission assembly. The successful development of two transmission assemblies, HW18709 and HW20716, further improved China National Heavy Duty Truck Group's heavy-duty vehicle power transmission product chain and improved its quality control over leading products.
