As a leader in the global transmission R&D field, Girf Power Technology (Suzhou) Co., Ltd. (GRC), a subsidiary of Germany's leading enterprise GIF in China, may not be famous due to its short establishment time. However, if you mention the China Development Alliance Corporation led by the National Development and Reform Commission and jointly established by more than ten domestic car companies, the industry may not be unfamiliar. Actually, Shanghai Automotive's dual-clutch transmission (DCT) project under the China FATF was led by GRC, and BorgWarner, which has dual-clutch and hydraulic module technologies, was the main project. supplier.
On the 3rd of April, during the interview with GRC, the reporter had the privilege of seeing GRC perform a durability test for the transmission of a main engine plant. This test can use the GIF-specific test software to carry out early failure analysis according to the customer's test specifications.
According to the engineer of the testing department of GRC, due to a lot of hands-on activities, the company's four laboratories are all in operation, and each laboratory can do various transmissions including MT, AT, AMT, CVT, and DCT. Synchronizer, differential test. The reporter noted that in order to be close to the actual operating conditions of the vehicle, GRC's bench test is that the engine drives the transmission instead of the motor.
As an ordinary car user, generally know that the engine needs to be matched with the car, but the role of the transmission matching may not be known to most people. In fact, even OEMs often do not fully understand which vehicle should be equipped with what kind of transmission, which needs to be evaluated and analyzed. As an automatic transmission that integrates modern electronic and control software, if it is not integrated with the engine and the vehicle, the transmission will not work properly, not to mention the configuration of parameters in various environments and under different operating conditions.
Mr. Fu Xiushi, Deputy General Manager of GRC Company, introduced GRC from transmission development, TCU control software development, to bench verification, vehicle verification, and its own various development and test tools, which can provide users with product development and prospects. Sexual project management.
The reporter learned that based on the existing four powertrain test rooms, GRC will also open the fifth test room dedicated to shift analysis. In response, Fu Xiuqi said that GRC's shift analysis software can solve the two difficult problems of shifting gear quality and noise of domestic manufacturers through evaluation and test analysis.
Talking about future market relations, Mr. Wu Li, general manager of GRC, stated that as the leader in the Chinese automotive transmission industry, GRC believes that more cooperation is needed and is also discussing future growth models with Chinese vehicle manufacturers.
In order to gain more strength in powertrain integration, GIF began its global cooperation with engine developer AVL last year. During the Shanghai International Auto Show in April, GRC will also hold a "2009 International Automotive Automatic Transmission Technology and Chinese Market Development Seminar" jointly with China SAE. At that time, there will be presentations by 17 Chinese and foreign experts from well-known companies, including: 6- to 8-speed AT, new CVT, front transverse 7-speed dry DCT, DCT and AMT for low-cost compact cars, hybrid transmission systems based on various transmissions, and optimized noise technology, transmission efficiency evaluation and improvement methods, etc. .
