What is the normal expected pressure value for a dual-clutch transmission?
1 Answers
The normal expected pressure value for a dual-clutch transmission is 2600. A value above 2600 is considered normal, while a value below 2600 may warrant replacement of the electro-hydraulic module. If the pressure is below 2600 but the vehicle can still operate normally, it is advisable to monitor the situation closely. The dual-clutch transmission originated from a patent filed in 1939 by Germany's Kegresse.A, which first proposed the design concept of dividing a manual transmission into two parts: one part transmits odd-numbered gears, and the other transmits even-numbered gears. The power transmission is achieved through two clutches connecting two input shafts, with adjacent gears alternately meshing with the gears on the two input shafts. By coordinating the control of the two clutches, it is possible to change the transmission ratio without interrupting power, thereby reducing shift time and effectively improving shift quality.
