交通运输专业英语 Lesson 4 Drivetrain The clutch plate is splined to the shaft extending from the transmission or “gear box” to the flywheel, commonly called a clutch shaft or input shaft.离合器片用花键与从变速器伸出的轴（通常称为离合器轴）联接，与飞轮接合。Power is transferred from the engine to the transmission, where it is routed through different gear ratios to obtain the best speed and power to start and keep the vehicle moving.动能从发动机传递到变速器，在这里他沿着不同的传动比路线传递以获得最佳的速度和动力来驱动车辆。 It is bolted to the engine flywheel and its main purpose is to exert pressure against the clutch plate, holding the plate tight against the flywheel and allowing the power to flow from the engine to the transmission.压盘用螺栓联接在发动机飞轮上，其主要作用是向离合器片施加压力，使离合器片紧贴飞轮，从而把动力从发动机传递到变速器。A higher torque is required to drive a heavily-loaded truck up a hill than that required to drive an empty truck on a flat road.重载货车爬坡比空车平路行驶需要更大的转矩。 The engine torque is applied at the input shaft of the gearbox and is transmitted to the countershaft by means of a smaller gearwheel on the input shaft and a larger gearwheel on the countershaft.发动机转矩施加到变速器输入轴上，并且通过输入轴上的小齿轮和中间轴上的大齿轮传到中间轴。The required gear ratio is selected by means of the gear lever, which moves a sliding sleeve on the output shaft so that the appropriate gearwheels will mesh with the corresponding gearwheels on the countershaft.所需的变速比用变速杆选择，变速杆移动输出轴上的滑动套，使适当的齿轮与中间轴上相应的齿轮啮合。 The driveshaft is not solidly bolted to the gearbox and the final drive, which moves up and down with wheel-spring movement.驱动轴没有用螺栓固定联接在变速器和主减速器上，它可以随着车轮-弹簧上下运动。It is essentially a double-hinged joint through which the driving shaft can transmit power to the driven shaft, even though the two shafts are somewhat out of line with each other.它实质上是一个双铰链连接，驱动轴能通过它把动力传给被动轴，尽管这两根轴并不完全在一条直线上。 Between the yokes is a center member shaped like a cross.在两个叉之间有一个十字形的中心件。(倒装句)The engine crankshaft being arranged at right angles to the rear axle, it follows that at the back axle some form of gearing must be provided to transmit
