Where is the Changan 7-speed wet dual-clutch transmission produced?
3 Answers
Changan's 7-speed wet dual-clutch transmission is produced in China. Introduction to wet dual-clutch transmission: The wet dual-clutch transmission uses engine oil to provide cooling and lubrication between the clutch housing and mating components. Wet dual-clutch transmissions offer better modulation capability and superior thermal capacity, enabling transmission of higher torque with less power loss and higher transmission efficiency. Operational characteristics: This wet clutch maintains stable performance with minimal changes in clamping force and friction coefficient after prolonged use. Working principle of wet dual-clutch transmission: The wet clutch utilizes hydraulic pressure during engagement. Throughout the process of clutch disengagement and full engagement, including relative rotation conditions, it controls the transmission of driving force. Similar to the slip control in automatic transmissions, it's easier to control smaller driving forces during slipping conditions, but requires continuous engagement pressure to maintain the engaged state. Unlike dry clutches, wet clutches primarily operate hydraulically and are generally used in automatic transmissions and continuously variable transmissions that demand higher smoothness. Additionally, compared to torque converters, they exhibit better slip suppression during driving, thereby improving fuel economy.
I bought a Changan UNI-T equipped with a 7-speed wet dual-clutch transmission. The salesperson mentioned it was manufactured in their own factory in Chongqing, which boasts advanced equipment. After using it for over a year, the transmission performance has been smooth without any jerking, making me look at domestic brands in a new light. As Changan's headquarters, Chongqing has strict management over the entire production line, and it's said to integrate international standards to ensure every component is thoroughly inspected. When chatting about cars with friends, we jokingly said the transmission responds quickly, making it fuel-efficient even in city traffic jams. Domestic production brings price advantages, lower maintenance costs, and easy access to parts replacement and repairs. Overall, I feel Chongqing as the production base is reliable, and the progress of Chinese manufacturing is impressive, with driving experiences on par with joint-venture brands.
As a car enthusiast, I'm particularly passionate about Changan's 7-speed wet dual-clutch transmission, which is mainly manufactured at the Chongqing plant. The facility boasts complete assembly lines and well-trained workers, ensuring the transmission's durability and performance. I've watched factory simulation videos online that showcase the precise assembly process, minimizing human error. This transmission adopts a wet design for better heat dissipation and extended lifespan, working in harmony with Changan engines to optimize fuel efficiency. It's frequently discussed in online communities, with many users reporting smooth, zero-lag shifting in models like the CS55. The Chongqing base's strategic location facilitates localized supply chains that accelerate production while supporting green manufacturing concepts, making me even prouder of domestic innovation.
