离合器外文翻译Transmission System A Basic Parts of the transmission system The transmission system applies to the components needed to transfer the drive from the engine to the road wheels. The main components and their purposes are (1) Clutch --- to disengage the drive --- to provide a smooth take-up of the drive (2) Gearbox --- to increase the torque applied to the driving road wheels --- to enable the engine to operate within a given range of speed irrespective of the vehicle speed --- to give reverse motion of the vehicle --- to provide a neutral position so that the engine can run without moving the vehicle (3) Final drive --- to turn the drive through 90°--- to reduce the speed of the drive by a set amount to match the engine to the vehicle (4) Differential --- to allow the inner driving road wheel to rotate slower than the outer wheel when the vehicle is cornering, whilst it ensures that a drive is applied equally to both wheels. B Clutch and Clutch Service In order to transmit the power of the engine to the road wheels of a car, a friction clutch and a change-speed gearbox are normally employed. The former is necessary in order to enable the drive to be taken up gradually and smoothly, while the latter provides different ratios of speed reduction from the engine to the wheels, to suit the particular conditions of running, A clutch performs two tasks: (1) it disengages the engine from the gearbox to allow for gear changing. (2) it is a means for gradually engaging the engine to the driving wheels, when a vehicle is to be moved from rest the clutch must engage a stationary gearbox shaft with the engine; this must be rotating at a high speed to provide sufficient...
