The 5th International CTI “Auto Transmission, Hybrid Electric Vehicle and Electric Vehicle†forum was held in Shanghai from September 21st to 23rd. Since 2002, the CTI Forum (CarTraining Institute, CTI for short) has been held in Germany for 14 sessions. Today, the CTI Forum is held every year in Germany, the United States, and China, becoming an industry conference in the world of automotive transmission. As the sister forum of the German CTI Forum, the 5th International CTI Forum held in Shanghai this year attracted industry experts from all over the world. In the 67 professional conferences of 8 branch venues, participants discussed the automobile drive and drive together. The latest technological developments and achievements in the field. 
Although looking ahead, everyone is talking about the transmission technology of passenger cars, but as a reporter of a commercial vehicle, Xiao Bian still pays more attention to the development of commercial vehicle transmissions. Which drive technology is more suitable for commercial vehicles? At the CTI Forum commercial vehicle branch, Xiao Bian found some answers.
AMT and AT is a tendency <br> <br> summarize the current transmission technology, is really dazzling. AMT, AT, DCT, CVT, as well as DHT officially released in this forum.
However, according to the chairman of the Advisory Board of the CTI Forum and Prof. Dr. Fritz Kucquet of the Braunschweig University of Technology in Germany, the CVT stepless transmission cannot withstand such a large torque transmission demand for commercial vehicles; although the performance of the DCT dual clutch is good, the status Not so stable, there has been a large-scale recall. As a production tool, if a commercial vehicle is out of condition for three days, it is estimated that no one can stand. Coupled with the complex and diverse Chinese roads, it is clear from the perspective of fuel consumption and driving safety that the automatic shift transmission (ie, the AT automatic transmission) is more suitable for the Chinese market.
In addition, he thinks AMT is also suitable. AMT has the advantages of high transmission efficiency, low fuel consumption, strong adaptability and low maintenance cost. It can also significantly reduce the driver's labor intensity and improve driving comfort. It is very suitable for commercial vehicle applications. For example, the 2015 V80 of SAIC Chase selected the AMT transmission from MARLIER, the supplier of FLL fleet, and Marelli’s company accurately calibrated and adjusted the usage status of domestic widebody light passengers.
Automated or light from light passenger <br> <br> as people began to automation, further increasing comfort requirements, such as the national energy saving policy tightening, prompting light commercial vehicle transmission automation market demand continues to grow. “The use of automatic transmissions in light commercial vehicles is a development trend, especially in the use of automatic transmissions in light passengers. There is more room for development and the process will be faster. Because passenger cars are more comfortable with respect to trucks,†said an industry source. .
At the CTI forum, ZF brought an 8-speed automatic transmission. 
According to Martin Vogel, project manager of ZF Corporation, the introduction of this product is the best opportunity to fully grasp the rise of automatic transmissions. Iveco's new NEWDAILY matches this transmission, allowing smooth and accurate shifts to be completed in less than 200 milliseconds. Compared to conventional manual transmissions, maintenance and repair costs can be reduced by 10%.
Not only that, this transmission is more fuel-efficient than the current equivalent, but it is also suitable for engines with a maximum torque of 1400 Nm. The shift performance is better than other transmissions currently available on the market for medium trucks, heavy pickups and passenger cars. Better.
Although matching the automatic transmission increases the price of a car by about 20,000 to 30,000 yuan, there is also demand in the high-end light truck market. "Such as Jiangling's Kaiwei series, Nanjing Iveco series, Futian Ouma, etc. can selectively install automatic transmissions to meet the needs of different customers." The industry insiders said.
