What the use about Electronic differential lock EDL, EDS or XDS?

In other words, even if you leave your car up completely, also never find a set of called "electronic differential lock (EDL, EDS or XDS)" of the device. So, this thing really have what use?We drove before turning situation as an example: in turning, because the inertial function, the vehicles outward focuses, the ground and inside the friction of the front wheel less, so the more easily wheels skid, once the wheel happen sliding, at this time due to differential redistribution torque characteristics, can put effective torque and can only achieve skid wheel sliding friction torque level, therefore, it is of adhesion of the front wheel drive torque is not enough, so vehicles will appear serious understeer (known as pusher), the headlights jilt not steering, lose the direction control.The Paris world expo in 1900, the "no engine, no gear box, no no no chain belt transmission shaft, no clutch" "electric cart", attracted the attention of the world. Also let many still sitting in the rich people eyes widen and for all people, that means a kind of brand-new unprecedented way of life.For a porsche speaking, a precursor of electric vehicles, for the rest of the two wheels also installed on the wheel motor nature is not hard, in order to participate in the contest impact speed record, he did take. So, four wheels equipped with wheel motor "los porsche,-" electric car and glorious become the world's first four-wheel drive cars, and it is also the first one, have four-wheel brake system car, this car is said to be broken some speed records, in the one hundred years ago people use" fast "to describe. But "raider" and not in performance to the car brings more advantages, in order to give four wheel motor and ensure sufficient supply power trip mileage, this car is just the weight of the battery was 1.8 tons, equivalent to one of the A6L audi a quality.While the electronic differential locks, will use the wheel sensor information and other sensor information to the vehicle of the working status and vehicle state decide, when monitoring to inside the wheel will occur skid or have skid, braking system can on the inside of the wheels of the front brake implementation, this is equivalent to improve the skid wheel this side of the adhesion coefficient, make the transfer to the effective wheel torque ascension, as long as this through the brake brings "adhesion coefficient is" the adhesion of the wheel than have adhesion coefficient is high, differential can transfer enough driving torque drive the lateral wheel rotation, make the car DVD control car in direction. Well, this is the "electronic differential lock", and before we mention all kinds of "lock" and "the limited slip" differential have nothing.Although the limited slip differential than real and differential lock in performance still have gap, but this only to ESP additional functions, no matter the cost structure is more simple or on (no structure...) And, therefore, the "electronic differential lock the principle of" get a wider range of applications-many cities SUV started to use "brake" between the wheel torque distribution, help improve road vehicle performance and through the ability.Hope that through this car cameras article and the enthusiasm to "differential" is a more direct and deep understanding, again face claim limited slip differential or what can lock up the "differential" lock the sellers or ZiYiWeiFei often like pseudo experts understand, you can put a pile of crap and lie more true to hear. And for immersed in the modification and driving the fanaticism of lovers, understand all kinds of differential performance, for modification and control the vehicle is essential.
