négykerékmeghajtású

Négyszerkerek-meghajtás, often abbreviated as 4WD, is a type of vehicle propulsion system that engages all four wheels for traction. This system is particularly beneficial in off-road conditions, where the terrain may be uneven, muddy, or slippery. The 4WD system can distribute power to all four wheels, providing better grip and stability compared to two-wheel-drive (2WD) vehicles.

There are two main types of 4WD systems: full-time 4WD and part-time 4WD. Full-time 4WD systems are permanently engaged and provide continuous power to all four wheels. This type is commonly found in off-road vehicles and some high-performance cars. Part-time 4WD systems, on the other hand, can be engaged or disengaged by the driver, typically through a switch or button. This type is more common in passenger cars and SUVs, offering a balance between on-road efficiency and off-road capability.

The 4WD system can be further classified based on how power is distributed to the wheels. In a permanent 4WD system, power is always sent to all four wheels. In a temporary 4WD system, power is sent to the rear wheels only when additional traction is needed, such as during acceleration or when the vehicle is slipping. Some 4WD systems also feature a locking differential, which prevents the wheels on one axle from spinning at different speeds, further enhancing traction.

Négyszerkerek-meghajtás is a versatile and robust propulsion system that offers significant advantages in challenging driving conditions. However, it may also result in increased fuel consumption and reduced on-road performance compared to 2WD vehicles. As such, the choice between 4WD and 2WD depends on the intended use of the vehicle and the driving conditions it is likely to encounter.
