They are rely on friction piece of structure, CAM slide block structure or worm gear and worm structure to achieve higher lock coefficient, and even the self-locking function.

Torque is slow speed on one side of the big,Electronic differential lock is not an really lock. Articles why side while the other side wheels skid wheel would have no power can't difficulty relief? This question is very good! We then discuss this topic."The point is that the techniques of MT, symmetry bevel gear differential internal friction torque MT usually is very small, so or so half the shaft speed not at the same time, the extent of the torque distribution limited, lock coefficient K values are usually was between 0.05 and 0.15, about half shaft torque than (M2 / M1) usually was between 1.1 and 1.4, so this kind of differential basically can think torque in any circumstances is the average of the distribution. And the torque distribution characteristics of average, decided to this kind of differential wheel around adhesion coefficient is significant difference"It is for symmetric bevel gear differential average distribution characteristics, so it appeared side wheels idling.And the other side but can't go on wheels good adhesion to the case".Because the car cameras characteristics of average distribution, about when the adhesion coefficient in different roads (such as a side road surface ice, snow and side shop), low adhesion of the road wheels can produce the driving moment of very small (wheel is too small, the friction so there is no way to get needs the reaction), and at this time of the good adhesion of the wheels also can get almost the same drive moment, and such driving moment have no way to make good adhesion of the wheels of progress on the road surface rolling (the engine power and has nothing to do with only at this time, on both sides of the divide adhesion coefficient is wheels), and even when you trample accelerator, also can make low adhesion on one side of the wheel lose adhesion idling, and to the side of the wheel is because driving moment enough to be car dvd forward. At this time, you will say, if not differential!The idea is very good! Based on the characteristics of this differential, we will have a "differential" lock, differential lock just as its name implies, is differential lock up the institutions, used to lock up the wheels differential (or so between half shaft) or differential between shaft and between driving axle), to deal with single or multiple wheel lose adhesion can't the difficulty relief. A differential locks.But forced the lock differential just "slip differential" family of a schematic, it is not perfect, because no matter how evolution of its control agencies, return or the need of human the lock and open. In comparison, belong to "lock itself type" differential of all kinds of mechanical and electronic faction of the limited slip differential (the) in flexibility on a "differential" lock more excellent, they rely on friction piece of structure, CAM slide block structure or worm gear and worm structure to achieve higher lock coefficient, and even the self-locking function, can not need human control, use their own structure reasonable distribution of torque.
