fter the wheel leaves the ground, turn, why a wheel is turning, a reversal
The principle of the differential is to drive the output power of the drive shaft to the left and right two drive wheels, because the left and right wheels in the turn when the speed is different, so can not use rigid connection, the middle of the gear structure of three words can not tell, anyway, Consumption of the smallest principle, that is, the energy automatically to the resistance of the smaller end, but the overall line with a law that is the revolver speed + right wheel speed = 2 times the drive shaft speed. In the case of ground, the engine must be stalled, the drive shaft speed is 0, when one of the drive shaft is forced to rotate, the other drive wheel at the same speed along the opposite rotation, that is the equation. This situation is applicable to two-wheel drive car drive wheel, full-time four-wheel drive there are more complex internal structure ... ...
