Where is the Changan 7-speed wet dual-clutch transmission produced?

[SilasMarie]

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.
