To find yourself on a soured stretch of road after prolonged rains is a classic situation for any owner of an all-wheel drive car who decided to move off the pavement. Many drivers mistakenly believe that having four driving wheels is enough to confidently pass swampy areas, but practice shows the opposite. Deep track It can stop even a prepared jeep if you do not know the basic principles of physics of movement in a viscous environment.
Before you let the car into the dirt, you need to soberly assess the risks and technical condition of your vehicle. Off-road rubber With an aggressive tread is a key success factor, but it is equally important to work with the transmission correctly and understand how the car behaves under load. In this article, we will discuss the basic driving techniques that will help you get out of the clutter with minimal losses.
Off-road riding is not only entertainment, but also a serious load on the units of units, requiring preliminary preparation. The wrong actions can lead to the fact that you need expensive evacuation and subsequent repair of the chassis. Let’s take a look at how to prepare for your departure and what to do if you’re already stuck.
Preparing the car for off-road departure
The first thing you need to reduce the pressure in the tires, which allows you to increase the spot of contact with the ground. On a solid surface. tire-pressure It is usually 2.0–2.2 atmospheres, but for dirt it should be lowered to 0.8–1.0 atmospheres. This will make the tire softer, and it will be able to bend irregularities, clinging to the sidewalls of the tread on the ground, instead of burrowing.
Be sure to check the condition of the protective elements of the body and bottom. Metal protection the crankcase of the engine and the gearbox must be securely fixed, since a blow to a stone hidden under water can penetrate the pallet. Also make sure that the sapons of the bridges and transfer box are removed above the expected water level or at least in good condition.
⚠️ Note: If you plan to dive above wheel level, make sure the air filter and exhaust system are airtight or raised (shnorkell), otherwise the engine is hydraulic shock unavoidable.
Do not forget to bring with you a basic set for recovery: a shovel, an axe, a cable and boards for laying under the wheels. Swan is an excellent assistant, but you should not rely on it alone, since it requires a reliable emphasis for its work, which is difficult to find in a clean field.
☑️ Pre-departure checks
Traffic technique: clutch and gas operation
The main rule of movement on slippery ground is the constancy of movement. If you stop in deep mud, it will be extremely difficult to move from a place, since the wheels will instantly burrow. It is necessary to accelerate in advance on a solid area and pass viscous places. coastingMaintaining the minimum required engine speeds.
You need to work with pedals very smoothly, without jerks. A sharp press on the gas will lead to the tearing of the wheels into a slip, which will instantly create a shaft of dirt in front of them. Use it. downshift in a transfer case, which will increase the torque on the wheels and allow you to move slowly, but with great traction.
If you feel the car is starting to knit, try rocking it while working with a clutch paired with gas. On a manual transmission, this is done by smoothly releasing the clutch until the moment of grasping and subsequent squeeze, creating momentum forward and backward. Nana gearbox You can use manual switching modes or just carefully work the accelerator pedal.
When driving in a deep track, try to keep the car even, avoiding diagonal wheel hanging, as this can block the differential.
When you lose speed, you lose the ability to overcome the resistance of the ground. Therefore, seeing a difficult area ahead, it is better to add gas in advance than try to push it into the tension.
Use of locks and electronic systems
Modern SUVs are often equipped with electronic stabilization and simulation locking systems. Blocking the differential (inter-wheel or inter-axle) allows you to transfer torque to wheels with better grip, ignoring those that hang in the air or are towed. Include rigid locks should only on solid ground or immediately before the obstacle.
Electronic assistants, such as Hill Descent Control Or descent control systems can be useful, but in deep mud they often strangle the engine to prevent slippage. In such situations, experienced jeepers prefer to turn off the stabilization system (see below).ESP OFF) to have full traction control.
| System system | Appointment | When to include |
|---|---|---|
| Reduced gear | Increased traction | Before entering the mud |
| Blocking the differential | Uniform wheel traction | Diagonal hanging |
| Disconnecting ESP | Freedom of rotation of wheels | In deep mud/snow |
Don’t rely on electronics alone, especially if your car isn’t a specialized SUV. Mechanical locking It is always more reliable and predictable in extreme conditions than software algorithms, which can overheat during long-term operation.
Choosing the Right Route and Trajectory
Visual assessment of the terrain is a critical skill. A deep track filled with water often hides sharp stones or stumps that can damage the suspension. Try to choose the route so that one of the wheels is always on a harder surface, for example, on the crest of the track or on virgin land next to the road.
Moving diagonally to the track direction (cross-way) helps to level the car if it is swayed. However, this method requires caution, as there is a risk of putting the car on its side when rolling. High clearance. It plays a secondary role in comparison with geometrical cross-country.
⚠️ Warning: Never try to cut a path through an unknown marshy place, even if it looks shallow. Peat slurry can suck a car on the roof in minutes.
If there is another car in front, try not to drive strictly on his trail, especially if he has already made meadows. It is better to move to the side to lean on the unspoiled ground, or, conversely, use a rolled-up track if it is hard enough.
What to do if there is only deep water ahead?
If detour is not possible, assess the depth of the cars in front or use a probe. Move slowly, creating a wave in front of you, but not to flood the engine.
Stucking Actions: The Rescue Algorithm
If the car is still standing, the first rule is to stop gas. Useless rotation of the wheels will only deepen the pit and turn the ground under the machine into porridge. You need to immediately stop, assess the situation and understand what exactly you caught: the bottom, the bridge or just hit the wheels.
Try to back off on the same trajectory you took. If this is not possible, use a shovel to dig the wheels. It is necessary to remove dirt not only in front and behind the wheels, but also between them, creating a gentle congress. Putting branches, boards or rugs under the driving wheels can give the necessary hook.
When using a winch, it is important to properly secure the rope. The mounting point should be strong, and the cable itself is stretched before work begins. If there is no winch, you can use the rocking method with the help of a cable and assistants that pull the car in time for your movements.
⚠️ WARNING: When working with a cable or winch, never stand in the cable tension line. When it breaks, it can cause fatal injuries.
In extreme cases, you can use a jack, but only by installing it on a wide area (board, stone) so that it does not go into the dirt along with the car. Raising the wheel, put a solid material under it to create a support.
Car care after mud baths
After successfully overcoming the off-road, you can not immediately park the car in a warm garage. Mud stuffed in the arches and on the bottom, contains aggressive reagents and moisture, which provoke metal-corrosion. It is necessary to thoroughly wash the car, paying special attention to hidden cavities and brake mechanisms.
Check the condition of the anthers of SRUS and Silentblocks. Mud and sand trapped inside the rubber elements act as an abrasive, quickly disabling them. It is also worth checking the level of oil in the bridges and distribution for water to get there (emulsion on the probe).
Timely washing and lubrication of hinges after leaving for the mud prolongs the life of the suspension and prevents expensive repairs in the future.
Don’t forget to lubricate all movable cable connections and hinges if they have been exposed to water. The water could have washed out the consistency lubricant, and by the next trip, the parts could rust or sour.
Frequently Asked Questions (FAQ)
Is it possible to ride on the dirt on a crossover?
Crossovers have a limited resource for off-road. They often don't. downshift and full locks, and the body can suffer from impacts. Short trips to dry primer are permissible, but climbing into deep mud on them is dangerous.
What kind of rubber to choose for dirt?
Regular departures require class rubber Mud Terrain (MT) with deep lamellae and powerful ground hooks. All-season or road rubber in the mud is useless and instantly washed away.
Should I change the oil after the trip?
If you have crossed water obstacles, be sure to check the oil in the bridges and dispensing. If it has a milky shade, then water has come in, and oil-change It is required immediately to avoid corrosion of the gears.
What to do if the engine is in the water?
Do not try to start the engine again. This is almost guaranteed to lead to a waterstrike and overhaul. Wait for a tow truck or help from comrades to tow.
