Everyone knows that a car has four wheels, the front wheel drive is called the front drive, the rear wheel drive is called the rear drive. What we see most on the road are front drive and front drive, the so-called front is the engine in the front, because most cars in life are front engine, so today we only discuss the advantages and disadvantages of front drive and front drive. What are the advantages and disadvantages of each?

Front - front advantages

1. Good linear driving performance. Drive in a straight line because you are pulling the vehicle in the walk, so the direction is better. It's like when we go to the supermarket and pull a trolley, it follows us wherever we go. And if you're pushing a trolley, it's too fast, it's not easy to steer.

2. High power transmission efficiency. The front wheel is close to the engine, so the torque loss is small. In addition, the power direction of the front driving vehicle is the same as the rotation direction of the wheel, while the power of the front driving vehicle has to change 90 degrees to be transferred to the rear wheel, resulting in a relatively large power loss. The front driving vehicle does not have this problem.

3. There are fewer parts for front-loading and front-loading vehicles, and the cost is relatively lower. The layout of the front front drive compared to the front rear drive car parts less central drive shaft and other parts. It can reduce the vehicle weight by 20~30kg. With fewer parts, the cost is lower, which is why most family cars prefer front-facing drives.

4. Large space for driving vehicles in front. Because of the front drive, the vehicle's engine and gearbox can be arranged more compact, leaving more room for the car. And, because there is no rear wheel drive shaft, the rear rear of the car can be made low or even non-existent, improving the comfort of the rear seat.

The disadvantage of the front drive

1. The locomotive is too heavy. The front front drive put the engine, gearbox, differential, steering machine, etc., in the front, so that the vehicle before the weight and light, when the vehicle turns violently, the vehicle dynamic performance is not good, very easy to push the head. This is the biggest disadvantage of the front drive.

2. Quick acceleration is easy to slip. When the vehicle is speeding up or starting, the front of the car will slightly tilt up, while the front of the car is driven by the front wheel. This tilt tends to cause the front wheel to lose its adhesion and cause the wheel to slip.

3. Nod seriously when braking. Because most of the weight is concentrated in the locomotive, when braking, the weight of the locomotive will aggravate the nodding effect of the vehicle, affecting comfort.

4. Push the head over the bend. The front wheels are responsible for both power and steering, and when turning, rapid acceleration or deceleration will affect the performance of the steering force. If you accelerate quickly on the curve, the vehicle will slip and lose steering force, causing the vehicle to sideslip out along the curve, also known as the push head.

Front and rear drive advantages

1. Better performance of the vehicle, enabling designers to fully display their talents. The forward-rear-drive engine can be mounted longitudinally, allowing for a narrower front wheel and a lower hood, which can reduce wind resistance and achieve better aerodynamic performance. Because each assembly is separate and independent, it is easier to produce and assemble and repair the vehicle.

2. You can get stronger grip when accelerating. We all know that sometimes things that we can't pull on the ground can be pushed, and the same is true of rear drives. When accelerating fast, the front of the car goes up, putting more pressure on the rear wheels, which gain more grip and prevent skidding.

3. Ensure sufficient steering force of the vehicle. The front wheel of the rear drive is responsible for steering and the rear wheel for power. Vehicle tire adhesion is constant, and if the tire is responsible for both steering and power, it can easily break through the tire adhesion in extreme weather (such as rain, snow and ice), resulting in poor steering. By separating the steering from the power, the rear drive ensures stronger steering for the front wheels.

4, with flexible steering characteristics, driving more fun. The rear drive is more likely to have a 50:50 weight ratio, more balanced vehicle weight, higher bend limit and more fun to drive. That's why sports cars tend to have a rear drive.

Front and rear drive faults

1. Higher driving skills. Rear-wheel drive gives the front wheels a push, and when you turn, it gives the front wheels more steering power, although it gives the vehicle more flexibility in turning, which is of course a good thing if you drive well. But if you're a bad driver, sudden acceleration in a corner can cause the back of the car to swing out of the corner, or even turn around and spin in place. This is what we call overturning. This is especially likely to happen on slippery roads such as rain and snow.

2. More parts and lower power transmission efficiency. Compared with the front front drive, the front rear drive vehicle has more parts, which increases the weight of the vehicle. At the same time, because of the transfer of power to the rear wheel, power loss. This is why rear drives are generally more expensive than front ones.

Conclusion:

Both front and rear drives have their own advantages. In general, most of our daily family practical vehicles are front-facing, because this arrangement costs less, and the space in the compartment is larger. And then drive generally used in high-end luxury cars. Because these luxury cars are less sensitive to price, they are looking for a better driving experience.
