THE GENERAL DATA

Transmission noise

• Noise of chain transfer – the howling or roaring noise, which level increases or decreases at change of frequency of rotation of country houses of the engine. Noise is absent at dispersal of the car with a small corner of opening ДЗ and in an engine operating time on a place at inclusion in a transmission of ranges D (Movement) or R (Backing).

• Noise of the main transfer – the rumble, which level depends on speed of movement of the car. The rumble is swept especially up at dispersal of the car with small degree of opening ДЗ and during movement накатом with the released pedal of an accelerator.

• Noise of planetary transfer – howling noise which is most strongly shown on 1st transfer and transfer of a backing and depends on speed of the car. Noise of planetary transfer can decrease or vanish at transmission switching on an adjacent higher step.

• pump Noise – the howling sound of a high-pitch tone increasing with growth of turns of the engine. Pump noise can be audible on all transfers.

• hydrotransformer Noise – howling noise which is usually audible only on the motionless car at inclusion in a transmission of ranges D (Movement) or R (Backing). Noise ГТ increases with growth of turns of the engine.
