When we talk about the car when the most frequently mentioned is the arrangement of the vehicle is divided precursor and rear-wheel drive two kinds, a lot of friends do not understand cars are confused precursor and after the flooding difference today Thank you all together to explore the difference between the precursor and after the flooding. VS precursor rear-wheel drive, there is much difference in the end, the election which is better? Listen to how old driver said
If the engine is the heart, then the transmission system is like a human spinal column, the power transmission system by the engine is transmitted to the limbs. Due to the different structure, it will produce a different drive modes, have an enormous impact on the car’s styling and interior space arrangements will. In the current domestic auto market, car or precursor majority, only part of the car uses rear-wheel drive form. So many people think that after the drive is the symbol of the sense of movement, like Cadillac CT4 is adopting the form of flooding. Then why most manufacturers have adopted precursor pattern here?
What is prodromal drive?
That is because for most vehicles, except 4-wheel-drive, most are not responsible for driving on four wheels, the precursor is by two responsible for front-wheel drive, in fact, the way we are familiar with, like rickshaw Republic of China is such a model, powered pulling people in front.
Then the drive mode is similar to the construction site of a small cart, powered pushed back.
precursor and rear-wheel drive car is about maneuverability for maximum impact vehicles have rear-drive before more people to manipulate the impression that the fact that it is not so ? We must first look at the two models cornering performance in fast cornering, understeer situation due to heavier weight precursor front of vehicles, and the front wheel at the same time is also responsible for providing power steering, so it is easy to appear, and then because the weight of the main drive in the rear, is likely to cause drift phenomenon, also known as oversteer. This is why like to play racing, drift reasons after playing friends have chosen to drive, of course, this is even more fun to drive.
but in everyday life, after all, not a road track, under normal circumstances is notWill appear when cornering fast, so not under extreme circumstances, the precursor to the difference between us and after the flooding of safe driving is not large.
Then turn, let us compare the precursor linear acceleration state and the difference between the drive, in the vehicle during acceleration, since the center of gravity of the body after the rapid shift, front appears inadequate grasp of soil fertility, the front-drive so often slipping phenomenon, after being rear-wheel drive is being tightly on the ground friction, vehicles can get faster acceleration. In the face uphill section, because the car is vertically downward by gravity, uphill process, the front wheel grip will deteriorate, while the rear wheels bear the burden of it is heavy. So-powered cars at the drive mode is more robust.
That is not to drive after drive performance in all sections are better than before, the answer is no, when faced with rain and snow, although the front wheel drive insufficient friction drive prone situation, but the vehicle does not skid or out of control occurs, it is more stable in comparison. Due to the rear wheel of the motorcycle force, could easily prone to slipping, so before the people’s consciousness just drove better handling in extreme mode, in everyday use, both in fact and there is not much difference.
why most of them use car prices precursor models do? The reason is from cost considerations, a lower front-drive production and after-sales costs. Transverse engine front-drive layout with the most cases, the engine, transmission, drive shaft position in the front axle, the layout is compact, simple structure. Then drive type of engine and transmission at the same axle, a power transmission shaft to the rear axle to transmit power required, relatively complex in structure. Bring the complex structure is rising costs, so the cost after the flooding of the engine also will be higher.
There are many prior model is changed after the precursor drive type vehicle, after the facelift, which are more representative of the BMW car 1 based on the case, an older system using a rear-wheel drive layout is, the change the new 1 Series models are changed after the transverse precursor layout, not only to reduce costs but also to expand the interior space to a certain extent. It is because after driving more and more parts, so the higher cost of keeping a car, need to transfer power to the rear wheels, the energy in the process of legendsThe loss is greater. So after driving more fuel it will be more easy to understand.
Summary:
It is because of the precursor and drive after fundamentally different, so different positioning of the two, the precursor more suitable for ordinary household, the price is relatively civilian models, greater interior space, fuel consumption is also lower. Then drive is suitable for speed there are certain requirements for intense driving luxury brands, so many high-end cars are rear-wheel drive mode is used, but there are also luxury car uses a precursor mode or directly on a four-wheel drive, so even specific models specific analysis, of course, only the best for you is the best.
