What is the difference between the DQ380 and DQ500 transmissions?

[DeNova]

There is basically no difference between the two. The DQ380 is an optimized version of the DQ500, using different dual-clutch systems for different vehicle models. Both are wet-type DSG transmissions. The DQ380 primarily replaces the 7-speed dry-type DQ200, while the DQ500 can handle up to 600 Nm of torque, whereas the 380 can handle less. The DQ380 is exclusively manufactured and used in China. More information about automatic transmissions is as follows: 1. Terminology: Automatic transmission, abbreviated as AT (Auto-Transmission), consists of a torque converter, planetary gears, and a hydraulic control system. It achieves gear shifting and torque variation through hydraulic power transmission and gear combinations. 2. Structural Features: The torque converter is the most distinctive component of an automatic transmission. It comprises a pump impeller, turbine, and guide wheel. The pump impeller and turbine form a working pair, with the pump impeller driving the turbine rotation via fluid. The guide wheel between the pump impeller and turbine creates a speed difference and enables torque variation through reaction forces. For the driver, simply pressing the pedal with varying force allows the transmission to automatically shift gears.
