11.2. The terms, the accepted reductions and abbreviations

THE GENERAL DATA

The description of some terms, reductions and the abbreviations connected with the device and functioning of automatic transmission is more low resulted.

Positions throttle заслонки (ДЗ):

• the Minimum opening ДЗ – corresponds to a corner of opening ДЗ which is necessary for transmission switching on adjacent higher transfer.

• Small opening ДЗ – approximately corresponds 1/4 courses of a pedal of an accelerator (25 percent opening ДЗ).

• Average opening ДЗ – approximately corresponds 1/2 courses of a pedal of an accelerator (50 percent opening ДЗ).

• Strong opening ДЗ – approximately corresponds 3/4 courses of a pedal of an accelerator (75 percent opening ДЗ).

• Full opening ДЗ – corresponds to a full speed of a pedal of an accelerator (100 percent opening ДЗ).

• Inclusion of the lowest step by full opening ДЗ – fast and full pressing the accelerator pedal, causing switching of a transmission adjacent lowest transfer.

• Nakat – car movement by the included transfer and completely closed ДЗ (the released pedal of an accelerator).

• Braking by the engine — movement of the car with completely closed ДЗ on the lowest transfer compulsorily included (manually).

Prominent features of process of a gear change:

• Slipping – appreciable increase of turns of the engine, not accompanied by corresponding growth of speed of the car. Slipping of frictional elements occurs in an initial phase of switching of transfer.

• Wavy switching – is accompanied by weak longitudinal accelerations of the car.

• Double blow – sharp and strong inclusion of a friction clutch or a tape brake of a transmission.

• Rigid switching – notable fast inclusion of frictional elements of a transmission.

• Delay – a delay of inclusion of transfer. Can occur because of a delay of inclusion of a friction clutch or a tape brake at partially or completely opened ДЗ or after inclusion manually the lowest range of a box.

• Final blow – occurs on a final phase of process of a gear change because of sharp full inclusion or схватывания frictional elements.

• Soft switching – almost imperceptible, very smooth switching of a transmission.

• Initial blow – occurs on the first phase of process of a gear change because of sharp initial inclusion or схватывания frictional elements.

• the Advancing – early switching of transfer (before the car will reach the speed corresponding to switching on adjacent transfer). Leads to an engine overload at switching on the higher adjacent transfer.

• Switching with overlapping of transfers – premature inclusion of a frictional element of the following transfer or delay of deenergizing of a frictional element of the previous transfer. Strong overlapping of transfers leads to intensive slipping of frictional elements under loading, to increase of loading and falling of turns of the engine.

• Later switching – transfer switching only after the car has considerably exceeded the speed corresponding to switching on adjacent transfer. It is accompanied by increase of turns and engine noise.

• Rupture of a stream of capacity, slipping of frictional elements – is accompanied by short-term, sharp increase in frequency of rotation of a shaft of the engine because of removal of loading in the course of a gear change.

• Sharp switching – stronger, than at "rigid" switching, inclusion of frictional elements. Sharp switching is undesirable at any degree of opening throttle заслонки.

• Pushes – a gear change accompanied by short-term longitudinal accelerations and delays of the car, similar to what can be observed at trailer towage. Sensitivity of pushes increases at blocked by

• Jolting – the repeating intensive longitudinal pushes similar to "Pushes" described in point, but stronger and fast. Jolting is usually observed in a certain range of speed of the car.

• Blow – sharp and strong inclusion of a friction clutch or a tape brake of a transmission.

• Cyclic switching – a chain of fast, short-term switchings of adjacent steps of a transmission, for example, 4–3–4-я... Transfers. Cyclic switching is accompanied by considerable change of frequency of rotation of a shaft of the engine.
