Is the Chery Tiggo 8's dual-clutch transmission dry or wet?
1 Answers
Chery Tiggo 8 is equipped with a dry dual-clutch transmission. The dry transmission transmits power through multiple friction plates and metal diaphragm plates connected to the input shaft. Power is transmitted when the friction plates and diaphragm plates are pressed together, and power transmission is interrupted when they are separated, which is the same principle as manual transmissions. Dry and wet dual-clutch transmissions share the same power transmission principle, but the working environments of the clutch driving plates and driven plates differ. The dry type operates in air, while the wet type works in oil. Dry dual-clutch transmissions have higher transmission efficiency, but since they can only rely on air for cooling, they are prone to overheating and wear in stop-and-go traffic conditions due to insufficient airflow. Wet dual-clutch transmissions are more durable and less likely to overheat. A clutch cooled by air is called a dry clutch. In use, the clutch should be able to engage and disengage from the power source easily and freely, and should not overheat even when operating in a semi-engaged state for short periods. Because dry clutches are not affected by the resistance of engine oil, they generally have faster engagement response and slightly stronger engagement force. Also, due to the lack of oil cooling, dry clutches usually adopt an exposed design for heat dissipation.
