References , proposed a dual-clutch two-speed gearbox, and the principle of uninterrupted power during the gear shifting process is similar to the working principle of the dual clutch transmission (DCT) assembled in traditional automobiles.
The dual clutch transmission (DCT) is different from other automatic transmissions in that it uses two clutches to control the clutch actuator and the gear selecting and shift actuator to achieve gear shift without power interruption.
Structure of dry dual clutch Working principle of dry dual clutch 2. The basic requirement for the dual clutch actuator is that it cannot self-lock and the motor must be continuously energized when the clutch is closed.
The dual clutch control part is mainly composed of two relatively independent oil circuits, controlling clutch C1 and clutch C2 respectively. The two parts control the oil circuit exactly the same, including safety valve, accumulator, pressure sensor and clutch control proportional valve.
Figure 5.23 shows the working principle of the hydraulic operated wet dual clutch. Under normal circumstances, the working pressure of the clutch C1 and clutch C2 is controlled by C1 proportional solenoid valve and C2 proportional solenoid valve respectively.
For a dual clutch system, to improve the driving comfort, the time when the clutch is in the sliding friction state is significantly increased (creeping function).
