Basic Troubles of Transmission MechanismСтр 1 из 2Следующая ⇒ The transmission of the engine torque to the driving wheels of the automobile must be smooth. There should be no vibration in the op- c rat ion 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.

TEXT Frame The foundation of the automobile chassis is the frame which provides support for the engine, body and power-train members. Cross members reinforce the frame. The frame is rigid and strong so that it can withstand the shocks, vibrations, twists and other strains to which it is put on the road. The frame provides a firm structure for the body, as well as a good point for the suspension system. There are two types of frames, namely: conventional frames and integral (unibody) frames (frameless constructions). Conventional frames are usually made of heavy steel channel sections welded or riveted together. All other parts of the car are attached to the frame. In order to prevent noise and vibrations from passing to the frame and from there to the passengers of the car, the frame is insulated from these parts by rubber pads. It is also important to insulate the frame in order to prevent metal- to-metal contacts. Frameless (unibody) constructions are called so because they are made integral with the body. The body parts are used to structurally strengthen the entire car. Some unibody frames have partial front and rear frames for attaching the engine and suspension members.
The exercises to be done after reading the text Упражнение 2. Найдите в тексте ответы на вопросы. 1. What does the frame provide? 2. Why is the frame rigid and strong? 3. What types of frames are there? 4. What is the conventional frame made of? 5. By what is the frame insulated from the other car parts? For what purpose? 6. What do you know about unibody frames? Упражнение 3. Подберите из правой колонки соответствующие окончания для предложений из левой колонки.
Упражнение 4. Переведите текст, не пользуясь словарем. The frame is a structural centre of any car as it provides support to the engine, body, wheels and power-train members. Cross members reinforce the frame and provide support for the engine and wheels. The frame is extremely rigid and strong. The engine is attached to the frame in three or four points and insulated in these points by some rubber pads to prevent vibration and noise from passing to the frame and thus to the passengers. There are two types of frames: conventional construction and unibody one. Упражнение 5. Прочтите диалог, а затем разыграйте его в парах. DIALOGUE Stas: Hi! Haven’t seen you for ages! How are you? Vlad: Hi! I'm perfectly well! I am working at a repairing shop. Very interesting I can tell you. S: What are you doing there? V: Now, we are testing the frame. You see, the driver has got into trouble. Something is wrong with his car. He thinks it is the frame. S: Has the car a conventional frame or a unibody frame? V: Unibody frame. S: I think you have to do a lot of work as body parts strengthen the entire car. V: Sure. We are testing all parts in order to find out the damage. S: I think you will cope with the problem. Notes: Haven’t seen you for ages – не видел тебя сто лет; get into trouble – попасть в беду be wrong with – что-то не так sure – конечно (без сомнения) find out the damage – отыскать повреждение соре with – справиться (с проблемой)
