Very often there are situations where the use of all-wheel drive is simply necessary. And this is not necessarily some kind of rally or competition of off-road vehicles, digging into the mud to the very glass. Ice and loose snow, mud and deep rut - all these are the reasons for the car slipping. To fix the problem, connect a second drive axle.
Instructions
Step 1
All-wheel drive connection diagrams may be different. It all depends on your vehicle. There are cars with permanent front wheel drive and a rear axle plug-in. Other cars are pushed all their lives by the rear wheels, but can, if necessary, turn on the front wheels. But whichever axle is connected, in all modifications of cars, several basic algorithms for turning on all-wheel drive can be distinguished.
Step 2
On modern foreign-made cars, four-wheel drive is activated by pressing the 4WD button or moving a special handle to a similar position. After that, electrical or hydraulic devices independently connect the second axis
Step 3
The classic part-time with manual all-wheel drive is designed for off-road use and at low speeds. But as soon as the speed of the car increases and reaches (in different cars in different ways) 40 or 60 km / h, the second drive axle is automatically disengaged.
Step 4
In domestic cars and foreign cars of an older age, to connect the all-wheel drive, it is necessary to move the transfer case lever to the 4WD position. In addition, you need to check if there are special couplings on the connected wheels. If there are clutches, then you need to set the switch on them also in the 4WD position.
Step 5
You can disconnect in any order - first the clutches, then the transfer case lever to the 2WD position. If you know that after a short distance, you will need to connect all-wheel drive again, then the clutches can not be disconnected, but do this only after the final exit from the difficult section of the road.
