On March 4, 2011, Chongqing Science and Technology Co., Ltd. undertook the key scientific and technological research project in Chongqing, "the new type of 2200Nm synchronizer-type new type transmission for heavy commercial vehicles" passed by the China Automotive Engineering Research Institute and Machinery organized by Chongqing Science and Technology Commission. An inspection team consisting of National Key Laboratory of Transportation, Chongqing Jiaotong University, Chongqing University of Technology and Chongqing Vehicle Inspection and Research Institute accepted and accepted the acceptance. The acceptance of the project will help promote the relocation of heavy-duty commercial vehicles by Haoyao Transmission Co., Ltd. and increase the growth of economic development.
The picture shows the deputy general manager of Lufang Transmission Co., Ltd. Liu Yudong (former left third) introduces the general situation of the 2200Nm synchronous-type planetary transmission of heavy-duty commercial vehicles independently developed and produced by the company to the members of the expert acceptance group.
Experts in the acceptance group examined the prototypes and production sites (as shown in the figure). Subsequently, the Chongqing Municipal Science and Technology Commission organized the acceptance meeting for the project at Jiaofang Transmission Company. The expert acceptance team listened to the project research report and technical report made by the gear transmission company project team, reviewed the relevant technical data, and after careful discussion and questioning of the project, the project concluded that the project had completed the research tasks specified in the contract.
The expert acceptance team pointed out that Fangyao Transmission Co., Ltd. provided complete and standardized data for acceptance and met the inspection and acceptance requirements. The project team developed the “Power Drive System Simulation Software for Heavy-duty Commercial Vehicles†and used advanced transmission gear finite element analysis software, transmission lubrication analysis software and The gear shaping software has formed the design, testing and mass production related technologies for heavy-duty commercial vehicle transmissions and key components with independent intellectual property rights; the transmission adopts barrel-type integrated housing, short-stroke double-cone synchronizer, and full cone The bearing support, the large flow pump forced lubricating system and the shift assist device structure solve the key technical problems such as heat treatment deformation and welding process of the large-size, large-load helical gear design and modification technology and key components, and the development is adaptable. The 2200Nm Synchronous Planetary Transmission of the power engine has advanced performance and has been applied to export vehicles. The market prospect is good. The S6500 and S6-160 have been developed and developed using the key technologies of the transmission torque capacity and reliability improvement that this project has achieved. , 5S-150GP three new products, achieved a good economy and Will benefit; the two project applications for invention patents, published three train a graduate 6; rational use of project funds, in line with the relevant requirements.
