What Causes the Clicking Sound During Low-Speed Gear Shifts in Wet Dual-Clutch Transmissions?
1 Answers
Wet dual-clutch transmissions producing clicking sounds during downshifts is a normal phenomenon. Reasons for abnormal noises during gear shifts: Since dual-clutch transmissions are equipped with two clutches, each independently connected to a set of gears controlling odd and even gears respectively, when the hydraulic servo system of the clutch or the transmission computer fails to precisely control the separation and engagement of gears, abnormal noises and jerks may occur. Gear shift mechanism: A wet dual-clutch transmission refers to a dual-clutch transmission where the clutch plates are immersed in transmission fluid. The gear shift is achieved through the alternating operation of two clutches, which ensures smooth gear shifting in wet dual-clutch transmissions. There are two types of dual-clutch transmissions: dry and wet.
