Перевести на русскийThe main units of the chassis are: the power transmission, the runninggear and the steering mechanism. The power transmission includesthe whole mechanism between the engine and the rear wheels. Thisentire mechanism consists of the clutch, gearbox, propeller (cardan)shaft, rear axle, final drive, differential and axle shafts.At the front end of the car is the engine. On the back of it is theflywheel. Behind the flywheel is the clutch. The clutch is a friction device connecting the engine with the gears of the gearbox. The mainfunction of the gearbox is to change the speed of the car.The power is always transmitted by the cardan shaft to the live backaxle. The final drive reduces the high speed of the engine to the lowspeed of the driving wheels. The differential enables the drivingwheels to turn at different speeds which is necessary when turning thecar. The foundation of the automobile is the frame to which differentchassis units are attached.The rear axle is capable of moving up and down about the frame. Therear axle is an important part of the transmission. It carries the greaterportion of the weight of the car.The steering mechanism is designed for changing the direction of thecar.The brakes are used for stopping the car, for decreasing its speed andfor holding the car position.
