Details Introduction

Working principle

Manual transmission: Cut off engine power through the clutch, manually operate the gear lever to switch between different gear combinations, and change the transmission ratio.
Automatic gearbox:
AT: The hydraulic torque converter transmits power, and the planetary gear set controls the clutch combination through the hydraulic system to achieve automatic shifting.
CVT: The hydraulic device adjusts the spacing between the conical pulleys, changes the position of the transmission belt, and achieves continuous variable speed.
DCT: Two sets of clutches work alternately, pre selecting the next gear to achieve quick shifting.
AMT: The electronic control system simulates manual shifting actions and automatically operates the clutch and shift fork.
