TRANSMISSION
Automobile transmission serves to transmit torque torque from the engine to the drive wheels of the vehicle, by changing its magnitude and direction and spreading in the determi- divided by the ratio between the drive wheels. Transmission by way of torque transmission divided into: • mechanical; • hydraulic; • electric; • combined. On domestic cars is widely dis- distribution of mechanical transmission. On buses and heavy haulers used hydromechanical transmission with automated gear shifting. Part of heavy duty vehicles equipped with electromecha- mechanical transmission with an electric motor-wheels. The General diagram of the powertrain The General scheme of transmission is determined by the layout car, number and location of major bridges, VI- the house transmission. Main components of transmission in the General case the include: • the clutch; • transmission; • main gear; • differential; • drive shafts — half shafts. For passenger cars according to the location of power Assembly and axle characterized by three layout scheme: 1. Classic scheme. The power unit is located IMPRES- Redi, drive axle — rear, the drive is carried out through the drive shaft and main gear with differentia- scrap. 2. Front-wheel-drive scheme. The engine, clutch, Ko timid transmission, final drive and differential charac- wife in front, longitudinally or transversely of the centerline of the AV- tomobile, drive axle — front. 3. Scheme with rear engine. The engine the clutch, gearbox, final drive and differential- Carl are in the back, longitudinally or transversely on tional centerline of the vehicle, drive axle — rear. The layout scheme of the freight cars characteristics characterized by the arrangement of the engine and cockpit: 1. Bonnet layout. The engine is located above the PE- rednim axle, cab — over engine. 2. Korotkolapye layout. The engine nad PE- rednim bridge, cabin partially pulled over the engine. 3. Cab-over-engine. The engine on the front axle, cab — over-engine. 4. The front cabin. The engine — behind front mos the one cabin maximum is shifted forward. Cars with manual transmission have class- the classical scheme layout (Fig. 51). Engine, drainpipe coupling. - tion, gearbox located in the front. Twisting mo- ment is transmitted to a propeller by transmission to the rear drive bridge. |
