离合器CLUTCH

离合器CLUTCH(中文3200字,英文1900字)
发动机产生动力用以驱动车辆。动力传动系将发动机动力传到车轮。传动系由飞轮后端到车轮之间的零件组成。包括离合器、变速器、传动轴和减速器总成。
离合器是位于发动机和变速器之间的一个旋转装置，它包括飞轮、离合器（从动盘）磨擦片、压盘、压紧弹簧、离合器盖及操作离合器所需的连接杆件等。它通过零件间的接触磨擦工作。这是离合器为什么会称为磨擦机构的原因。离合器接合后，给变速器传递所有的发动机转矩磨擦没有打滑。离合器也被用于在变速器传动比变换时从传动系中分离发动机。

CLUTCH
The engine produces the power to drive the vehicle. The drive line or drive train transfers the power of the engine to the wheels. The drive train consists of the parts from the back of the flywheel to the wheels. These parts include the clutch, the transmission, the drive shaft, and the final drive assembly (Figure 8-1).
The clutch which includes the flywheel, clutch disc, pressure plate, springs, pressure plate cover and the linkage necessary to operate the clutch is a rotating mechanism between the engine and the transmission (Figure 8-2). It operates through friction which comes from contact between the parts. That is the reason why the clutch is called a friction mechanism. After engagement, the clutch must continue to transmit all the engine torque to the transmission depending on the friction without slippage. The clutch is also used to disengage the engine from the drive train whenever the gears in the transmission are being shifted from one gear ratio to another.
