Mechanical 4WD falls down from the altar, and Audi

Mechanical 4WD fell off the altar? Why is the electronic 4WD used by Audi Quattro good?

in the twinkling of an eye, the Spring Festival in 2019 has passed. Looking back on the past automobile market, SUV is still in a very hot position. In this case, major automobile manufacturers agreed to consider taking practical measures to win. Therefore, it is no longer a simple market segment for products, but further upgrading product performance. One of the reasons for the good sales of SUVs is that in addition to its practical attributes, it also takes into account the ability to adapt to complex road sections, that is, the 4WD system. Today, let's talk about the 4WD system carried by SUVs

as far as the current situation is concerned, the driving mode of automobile is simply divided into three types: front drive, rear drive and 4WD. The most common thing in our daily life is the front drive, which is widely used in household models, while the rear drive is reflected in some performance models, while the 4WD model also needs UTM to play a greater role, which is carried by the high configuration version of some models. The reason is that the manufacturing cost increases. When it comes to 4WD, many people have the impression that the 4WD model handles well. In fact, it is far more than that. Theoretically, the 4WD model is the best vehicle driving solution at present. With 4WD, the vehicle can face more complex road conditions. Different from the traditional injection molding in structure, the 4WD system is divided into electronic 4WD and mechanical 4WD

although mechanical 4WD has absolute advantages in 4WD capability, its disadvantages are also clear at a glance. The first is the increase of its cost, and the R & D demand will be further improved. Moreover, due to the mechanical structure, the increase of fuel consumption is inevitable, so the mechanical 4WD is generally equipped in professional off-road models. And the driver needs to have a certain understanding of the whole system and have a certain foundation in operation before he can give full play to his performance

compared with the electronic 4WD, because many of them rely on the automatic control of the computer system, the operation is basically not difficult. Switching the 4WD mode is also in place with one key, without complex operation, and the comfort and fuel saving will be better. However, without the support of mechanical parts, the road conditions that can be adapted to are very limited, which is absolutely sufficient for daily driving

the electronic 4WD is widely used in the current SUV market. For example, bog Warner, the leader in the electronic 4WD industry. At present, the fifth generation intelligent four-wheel drive system of BorgWarner has come out, which is more compact in system structure, more intelligent in control and unprecedentedly powerful in four-wheel drive performance. It relies on the central multi plate clutch limited slip differential to realize the torque distribution between the front and rear axles. When driving on normal roads, the main cost of the car lies in its service life, and the torque distribution of the front and rear axles of the car is 100:0; When the adhesion of the front and rear discs is poor, the computer can automatically control the power output of each disc on the road surface. When the front wheels have no adhesion and only the rear wheels have adhesion, the Haldex 4WD system can distribute 90% or more power to the rear axle in a short time, so as to help the vehicle get out of trouble easily

at present, the 4WD model of Lingke 01 is equipped with this 4WD system. In the fun and wild activities held not long ago, we also witnessed the strength of this set of 4WD, which can still maintain a good driving attitude when dragging a nearly 2-ton drag RV. When the vehicle is in the diagonal support state, it can quickly detect and inhibit the wheel idling, and automatically distribute power to the tires with grip

as an urban SUV, the 4WD system of Lingke 01 focuses more on the handling performance on the road. The control program is more intelligent. By sensing the current driving state of the vehicle and cooperating with the front and rear EDL electronic differential function, it can more accurately control the torque of each wheel, making it have good tracking in curves and slippery roads. In terms of actual off-road, the performance of Lingke 01 is also commendable. In the face of wheel slip, the 4WD system can quickly brake the wheels and transfer the power to other wheels with adhesion. In our previous field test, Lingke 01 can pass smoothly in the face of cross axle, shell pit and even 45% ramp

in addition to Lingke 01, the famous Land Rover Discovery is also equipped with a four-wheel drive system from BorgWarner. Its perfect all terrain information feedback system can achieve intelligent off-road. Even a novice who doesn't know off-road can pass through bad road conditions with strong computer support

with the progress of science and technology, people are more and more inclined to the electronically controlled 4WD system. Even the best Audi Quattro 4WD system in the industry, the latest Quattro ultra also adopts electronic 4WD. The more intelligent regulation mode of electronic 4WD and lower starting difficulty further improve the fuel economy and make the road performance more prominent. Therefore, if you are not a hardline off-road enthusiast, the electronic 4WD is more suitable for driving on urban roads. Don't blindly "superstitious" the mechanical 4WD
