Automated trucks - China National Heavy Duty Truck AMT transmission mass production

The mass production of the "SMARTSHIFT-AMT" transmission has significantly bolstered Sinotruk's ambition to play a more pivotal role in China's heavy truck industry. This development marks a key milestone in the company’s journey toward technological leadership and market expansion. On December 12, 2008, at the CNHTC Transmission Production Line in Zhangqiu, Jinan, Shandong, Wang Baozhong was overseeing the final steps before the large-scale production of the AMT transmission. He carefully directed two workers to remove a newly packaged SMARTSHIFT-AMT unit from a forklift, marking an important step in the transition from manual to automatic transmissions. As head of the technical department, Wang was preparing for the upcoming mass production, ensuring every detail was meticulously checked. Wang and his team had been working on this moment for months. By December 19, the flexible production line with a capacity of 30,000 units would begin mass production of the AMT transmission. To ensure reliability, Wang conducted a thorough inspection of the entire process. “We are in the most intense phase before mass production,” he said. “Every process is critical, and we have adjusted the line according to AMT requirements. The main focus now is on maintaining cleanliness and protection.” A week later, on December 19, more than 1,600 international distributors gathered in Jinan for the year-end business meeting of China National Heavy Duty Truck. President Cai Dong emphasized the importance of the AMT transmission as a strategic pillar for the future of the heavy truck market in China. The SMARTSHIFT-AMT was not just a product—it was a preemptive move into a largely untapped market. Cai Dong was pleased to see that dealers remembered the abbreviation AMT. One dealer even placed an order for 50 high-end HOWO-A7 tractors equipped with the SMARTSHIFT-AMT transmission on the same day. Despite the global financial crisis impacting the Chinese heavy truck market in late 2008, Sinotruk continued to grow. They introduced the EGR engine, acquired Datong Gear Factory, and achieved a major breakthrough by industrializing domestic automatic transmissions. Sinotruk was not the first to explore AMT technology, but it was among the few to successfully bring it to mass production. While European markets had already adopted AMT extensively, China lagged behind, relying on foreign suppliers like ZF. However, Sinotruk’s efforts marked a turning point. Chairman Cai Dong remained confident despite the economic downturn. “Opportunities exist in any situation,” he said. “It depends on whether you can seize them.” His approach was proactive, often visiting markets to spot emerging trends. In 2005, technicians from Cai Dong’s team observed that 20% to 30% of European road tractors used AMT, a trend that was growing. Unlike traditional AT transmissions, which rely on hydraulic systems, AMT uses a computerized TCU to control shifting, resulting in better fuel efficiency—up to 10% lower consumption compared to ATs. Moreover, AMT eliminates human error by simulating the expertise of skilled drivers, making it more efficient than manual transmissions. Recognizing this potential, Cai Dong pushed for the development of AMT in China, aiming to secure a competitive edge. The project faced challenges, particularly due to the lack of in-house transmission manufacturing. However, after separating from Weichai and building its own transmission base, Sinotruk gained the necessary infrastructure to develop AMT independently. By 2008, all preparations were complete. The AMT project officially began, starting with a 16-speed transmission. With Europe leading the way, Sinotruk aimed to stay ahead of competitors like FAW and others who were also investing in AMT. To accelerate development, Sinotruk partnered with WABCO, a German supplier known for its work with Mercedes-Benz and Volvo. WABCO provided the TCU framework, while Sinotruk’s engineers customized it for Chinese conditions. This collaboration ensured full technological ownership and allowed for localized improvements. Despite the partnership, challenges remained. Calibrating the system for China’s diverse road conditions and heavy loads proved difficult. Over 50 test vehicles were used, accumulating over 600,000 kilometers of testing. Engineers like Li Fa worked long hours, solving complex issues that required both technical skill and creativity. One such challenge involved developing TB (transmission box brake) technology, which was initially costly. But through independent research and innovation, Sinotruk managed to solve the problem quickly, impressing WABCO engineers. By 2008, the AMT transmission had proven its worth, reducing fuel consumption by 5–10% compared to manual models. Users in Beijing and Inner Mongolia praised the performance, signaling strong market potential. Looking ahead, Sinotruk planned to expand AMT to other models, including 12-speed versions. The launch of the HOWO-A7, featuring AMT as standard, further highlighted the company’s commitment to innovation and competitiveness. With features like E (economy), P (power), and C (crawl) modes, the A7 offered enhanced driver experience and fuel efficiency. At a price of around 309,800 yuan, it was far more affordable than comparable European models. While Sinotruk remained cautious about the market, the company aimed to break the dominance of multinational suppliers and capture domestic and overseas opportunities. With AMT’s potential to transform the heavy truck industry, Sinotruk was well-positioned for future growth.
