1.7.3. Management of a mechanical transmission
|Fig. 1.134. Modes of switching of a mechanical transmission
The mechanical box of the car has the standard scheme of gear shifting. It is represented on the handle of the lever of gear shifting. All transfers for advance have synchronizers and consequently easily join.
At inclusion of transfer of a backing, after a full stop of the car detain the gear shifting lever at least on 3 св neutral situation. After that move the lever to the provision of transfer of a backing.
When switching lever from the provision of the 5th transfer to the provision of the 4th transfer watch to including by mistake the second transfer. Such sharp gear shifting can cause excessive increase in number of turns of the engine (the shooter of a tachometer in a red zone). Excess of the most admissible turns of the engine can lead to engine damage.
Before inclusion of transfer it is necessary to squeeze out completely a coupling pedal, and then slowly it to release. The repeated pressing a pedal of coupling is necessary for making only after its full reset. Do not hold a foot on a coupling pedal during car movement. It can result in wear of a disk of coupling. Do not apply coupling to car deduction on a bias, use for this purpose the parking brake. Do not allow a sharp and repeating otpuskaniye of a pedal of coupling.
For economic driving it is recommended to switch transfers on the speeds specified in table 1.5.
Receptions of the correct driving
Do not slide under a bias on neutral transfer: it is very dangerous. Always hold transfer of the included.
Be not accustomed driving at which it is necessary to brake sharply. It conducts to an overheat of brakes and loss of efficiency of their work. On long descents it is necessary to apply braking by the engine to prevention of an overheat of brakes (including low gears).
At low gear inclusion slightly brake the car. It will help to prevent excessive increase in number of turns of the engine and will exclude its breakage.
At a strong lateral wind reduce speed of movement of the car. It will improve its controllability.
Before inclusion of transfer of a backing, be convinced that the car is completely stopped. Otherwise it is possible to damage a transmission. to transfer the lever to the provision of a backing, at first squeeze out a coupling pedal, transfer the lever to neutral situation, wait 3 with, and then transfer the lever to the provision of a backing.
Be careful at movement on the slippery road and during braking, acceleration and gear shifting. On the slippery road sharp change of speed of the car can lead to loss of coupling of wheels with the road and control loss over the car.
At control loss over the car on high speeds the risk of a perevorachivaniye of the car considerably increases.
Management loss often arises, when two or more wheels move down from a road track, and the driver tries to return the car back on the road.
If the car moved down from a road track, avoid sharp turn of a steering wheel. Instead reduce speed of the car before again driving on the road.
