In Europe and the United States, heavy-duty trucks equipped with AMT (mechanical automatic transmission) are commonplace. In China, due to the price, it is not popular. However, AMT is moving toward us faster than expected.
On April 14, ZF hosted the AMT test drive test in Shanghai. Hager KLQ6119GA city bus (equipped with ZF 6-speed mechanical automatic transmission), youth JNP6120 double-deck passenger car (with ZF 12-speed mechanical automatic transmission) and Dongfeng Tianlong heavy truck, German MAN tractor, XCMG 110-ton truck crane, 200 Tons of vehicles equipped with ZF AMT, such as full-surface truck cranes, are used for test driving by media reporters, users and related personnel at the event site. The driving maneuverability, comfort and good fuel economy demonstrated by ZF AMT have been well received by everyone.
Wolfgang Schilha, President of ZF Bus Technical Business Unit, said: “Last ten years ago, ZF headquarters began researching and developing AMT transmissions. Today, ZF series AS Tronic has a wide range of commercial vehicle applications. The range of applications, whether it is AS Tronic for heavy trucks, or AS Tronic mid and AS Tronic lite for medium and light trucks, is known for its flexibility, safety and economy. The eTronic automatic transmission for vans and the TC Tronic transmission for smooth start-up of heavy-duty trailers with a total mass of 250 tons.â€
At the event, the reporter took a test ride of a Hager passenger car and a youth passenger car equipped with ZF AMT. The feeling was very smooth, and the driver said that the maneuver was very labor-saving. Liao Liheng, General Manager of ZF Transmission Technology (Suzhou) Co., Ltd., introduced: “In 2006, ZF AMT began to be matched in China. In 2007, Young Neoplan launched the first road passenger car equipped with ZF AMT. Now more than 100 vehicles have been introduced to the market, which is nearly 4 years old. ZF has found a serious attitude in problem solving and problem solving. After a long, small batch and systematic trial operation, ZF has achieved good results. Market response while ensuring the reliability of volume operations."
During the trial ride of the Dongfeng Tianlong tractor and the German MAN tractor, the reporter had a deeper understanding of AMT. The reporter first took the German MAN tractor, and its advanced nature and driving smoothness needless to say, just like sitting in a car. Shanghai Huafeng Logistics' Shanhua has just purchased this car. His logistics company mainly transports precision instruments and hazardous chemicals. Then, the reporter also took the Dongfeng Tianlong tractor, and the driver Yuan Guanwen told reporters that he drove this car from Shanghai to Shiyan. He felt good along the way and did not need frequent shifts. And according to his statistics, the fuel-saving effect can reach more than 5%.
“We have reason to believe that after 2010, AMT will have an unstoppable advantage in technology and become a new milestone in the application of transmission technology. It can automatically shift gears and save fuel, at least to save 5,†said Dai Zhangyu, vice president of ZF China. From 6% to 6%, the higher the oil price, the more obvious the advantages.ZFT's AMT transmissions are actually improvements and enhancements in the traditional technology, through the optimization of existing technologies, to achieve the effect of energy-saving emission reduction, which is also the development of European technology In Europe, this is a very mature product, and almost 90% of road passenger coaches or tourist coaches are using AMT."
On the same day, the signing ceremony of the ZF AS Lite transmission cooperation memorandum for batch use of Suzhou Industrial Park Public Transportation Co., Ltd. was held in Shanghai. 20 AMTs will take the lead in servicing the park bus. On the same day, Dongfeng Motor Co., Ltd. and Yichang Logistics signed the procurement intention, and 500 ZDFRONIC transmissions with Dongfeng Tianlong tractors will be put into use according to the company's logistics.
Huang Gang, General Manager of Dongfeng Commercial Vehicle Co., Ltd., said at the signing ceremony: “Dongfeng Commercial Vehicle Co., Ltd. has always been adhering to the scientific and technological innovation and has tried its best to provide users with reliable, professional, and caring service guarantees and create maximum value for customers.†Huang Gang said Through the exchanges and cooperation with ZF Corporation, the quality of Dongfeng Tianlong has been further improved, and more practical examples have been used to prove the value created by Dongfeng Tianlong for its customers.
Ji Xiaogang, chief vehicle engineer of Dongfeng Tianlong, said: Dongfeng Commercial Vehicle Company and ZF Corporation launched the work of matching ZF automatic transmissions on Dongfeng Tianlong series models in 2009. After many rounds of trial production and calibration work, they are now ready for mass production. Based on the conditions, preliminary estimates will be delivered to customers around July.
