What's the difference between a front drive and a rear drive? What car should I choose to drive in snowy days?

Snowy weather is common in winter in northern China, but it is incomparable to wear short sleeves to go shopping in winter in some parts of southern China. It is difficult for people to drive in snowy days, and the speed should not be too fast, because the tires are easy to slip and the braking distance becomes longer. Recently, a friend asked Xiao, is driving in the snow a good driver or a good driver? The following Coolpad will analyze it for everyone, hoping to help everyone drive in winter.

What do you mean by front drive and rear drive?

We usually refer to the front and rear drive of the car, which refers to the position of the driving wheel. The front wheels drive the front wheels and the rear wheels drive the rear wheels. The force point is different. To put it bluntly, the front drive is towing the whole vehicle, and the rear drive is pushing the whole vehicle.

Advantages of the front drive: because the engine is front-mounted, the power is directly transmitted to the left and right front wheels by the half axle after passing through the gearbox and differential. This makes the rear row more space and better ride comfort. Meanwhile, the processing cost and the maintenance cost are low.

Disadvantages of the predecessor: due to the front center of gravity, "nodding" is obvious when braking suddenly; The driving force is slightly poor. When going uphill, the center of gravity moves backward, and the adhesion of the front wheel decreases.

Advantages of rear wheel drive: rear wheel drive, outstanding driving force; The center of gravity of the whole vehicle is evenly distributed, and the driving and braking are more stable. Generally, the rear drive is more comfortable than the front drive! Some high-end cars have more rear drive!

Disadvantages of rear drive: the transmission shaft and differential affect the spatial layout of the whole vehicle, and the rear space is forced to compress; Processing costs and maintenance costs are high.

If it is an automatic transmission with snow mode, you can choose snow mode, but if it is a manual transmission, you must choose the second gear to start.

Because the first gear is relatively large, the torque transmitted by the engine to the driving wheels is also large. Everyone knows that ice and snow roads are the easiest to slip, and a little oil on the rear wheels may slip. If you start in the second gear and add manual power, the torque of the engine to the driving wheel will be reduced. This reduces the chance of slipping.

2. It is recommended to replace snow tires.

Due to the special material of snow tires, the tire surface will be softer at low temperature, which increases the friction and is not easy to slip. If it is an ordinary tire, the colder the weather, the harder the surface. Replacing snow tires is a good way to solve the slippery road surface.
