kétkerékhajtás

Kétkerékhajtás, often abbreviated as 2WD, refers to a type of drivetrain system in a vehicle where only two wheels are powered by the engine. This is the most common configuration found in the majority of cars and trucks manufactured today. The engine's power is transmitted through the transmission and driveshaft to either the front wheels (front-wheel drive, FWD) or the rear wheels (rear-wheel drive, RWD).

Front-wheel drive is prevalent in smaller, more economical vehicles. In this setup, the engine, transmission, and differential are typically located at the front of the car, driving the front wheels. This configuration generally offers good traction in most road conditions and can be more fuel-efficient due to a lighter overall weight and fewer components.

Rear-wheel drive is often found in larger sedans, sports cars, and trucks. Here, the engine is usually at the front, and power is sent to the rear wheels via a driveshaft. RWD systems are known for providing better handling and weight distribution, particularly in performance applications, as the front wheels are solely responsible for steering.

While two-wheel drive systems are simpler and more cost-effective to produce than four-wheel drive (4WD) or all-wheel drive (AWD) systems, they may have limitations in adverse weather conditions such as snow, ice, or off-road situations where enhanced traction is required. The choice between FWD and RWD often depends on the intended use, performance goals, and cost considerations of the vehicle.
