Read and translate this text: Chassis

The main units of the chassis are: the power transmission, the running gear and the steering mechanism. The power transmission includes the whole mechanism between the engine and the rear wheels. This entire 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 the

flywheel. Behind the flywheel is the clutch. The clutch is a friction de-vice connecting the engine with the gears of the gearbox. The main function of the gearbox is to change the speed of the car.

The power is always transmitted by the cardan shaft to the live back axle. The final drive reduces the high speed of the engine to the low speed of the driving wheels. The differential enables the driving wheels to turn at different speeds which is necessary

when turning the car. The foundation of the automobile is the frame to which different chassis units are attached.

The rear axle is capable of moving up and down about the frame. The rear axle is an important part of the transmission. It carries the greater portion of the weight of the car.

The steering mechanism is designed for changing the direction of the car.

The brakes are used for stopping the car, for decreasing its speed and for holding the car position.

Exercise 10 Translate the text into Russian using a dictionary:

Basic Troubles of Transmission Mechanism

The transmission of the engine torque to the driving wheels of the mitomobile must be smooth. There should be no vibration in the op- c ration of transmission mechanism within the range of travelling speeds.

The indications of malfunctions in the transmission mechanism

components are as follows:

1.incomplete disengagement of the clutch;

2.difficult engagement or self-demeshing of gears;

3.run out and vibration of the cardan-drive shaft.

What to do in these cases:

1.Check the free travel of the clutch pedal and adjust it.

2.Check the oil level in the gearbox housing and wash breather channel.

3.Check to see that all the fastening bolts are securely tightened and that the trunnion crosses fit properly the bearings, and the bearings, in turn, the universal-joint forks. Please, evaluate your answer on your card!
