The HW18710T full synchronizer high-torque gearbox developed and developed independently by Dazhe Co., Ltd. was successfully off the assembly line at the Grand Tooth Assembly Plant on April 28, and successfully passed the bench and static torsion test and was sent to China National Heavy Duty Truck Group Corporation. Carload road test. This signifies that the gearbox has the processing capacity in the big gear and provides the necessary guarantee for the scheduled delivery of Iranian export vehicles.
On March 6, General Manager Cai Dong of China National Heavy Duty Truck Group Corporation chaired the "Transmission Research and Development Conference", demanding that Big Tooth Company fully organize and develop the HW18710T full synchronizer gearbox according to the needs of the Iranian market, and ensure delivery to the Group before May 10th. The company's five prototypes are used for loading verification. At the same time, it is striving to have a batch production capacity at the end of May to ensure the scheduled delivery of Iran's export vehicles.
According to the strategic deployment of China National Heavy Duty Truck Group Corporation, Big Tooth Company quickly established the HW18710T Full Synchronizer Gearbox Project Development Leading Group headed by General Manager Wu Zhenghe and immediately presided over the project kick-off meeting to meet the technical requirements of the entire project. Process requirements, quality requirements, trial production schedules, and time nodes put forward clear requirements. Technical centers, engineering manufacturing department, equipment department, production department, production preparation workshops, new product workshops and other fast-moving activities performed their duties, went all out to overcome difficulties, and carried forward the spirit of dare to dare to fight hard, and created One miracle after another. The entire design of the drawing took only 16 days. The preparation of the process to the manufacturing process took 36 days. By April 28, the prototype had been tested on the bench. However, everything was not easy. In the next bench test, engineers and technicians used their wisdom and experience to solve one or more technical problems. By May 12, all tests were completed successfully. The test data meets the technical design requirements. The successful trial production of the HW18710T full synchronizer gearbox has not only successfully completed the R&D tasks handed down by China National Heavy Duty Truck Group Corporation, but also created a miracle of large teeth R&D trial production new products. It is also using practical actions to implement the scientific development concept.
