当离合器踏板按下时，电缆或者液压活塞将推动离合器分离叉杆，离合器分离叉杆推着外伸的轴承贴在膜片弹簧的中间。

When the clutch pedal is pressed, a cable or hydraulic piston pushes on the release fork, which presses the throw-out bearing against the middle of the diaphragm spring.

拨叉带动分离轴承进人压盘中部，从而使压盘和离合器盘分离，离合器盘和发动机飞轮分离。

The fork moves the release bearing into the center of the pressureplate. This causes the pressure plate face to pull away from the clutch disc, releasing thedisc from the flywheel.
