1. A planetary gear train automatic limited slip differential, consisting of a main differential, a planetary gear train differential controller, a left axle shaft, a right axle shaft, and a clutch;
wherein the planetary gear train differential controller is composed of a first planetary gear train differential controller unit and a second planetary gear train differential controller unit;
the first planetary gear train differential controller unit being composed of a first planetary gear train and a first overrunning clutch connected to the first planetary gear train, and the second planetary gear train differential controller unit being composed of a second planetary gear train and a second overrunning clutch connected to the second planetary gear train;
the planetary gear train differential controller being arranged at the right axle shaft at the right side of the main differential;
the clutch being composed of a left clutch and a right clutch, and the left clutch and the right clutch are coupled together by jaws or disengaged from each other;
an inner ring of each of the first overrunning clutch and the second overrunning clutch and the left clutch being connected into a whole by splines, and the right clutch and the right axle shaft are connected together by a spline;
wherein the first planetary gear train differential controller unit is configured to control a rotational speed of a right wheel to be not lower than a set minimum rotational speed nmin, and the second planetary differential controller unit is configured to control a rotational speed of the right wheel to be not higher than a set maximum rotational speed nmax;
the first planetary gear train including a first support, a first large sun gear, a first planetary gear, a first small sun gear, and a first planet carrier;
the second planetary gear train including a second support, a second large sun gear, a second planetary gear, a second small sun gear, and a second planet carrier;
wherein the first large sun gear and the first support are connected together by a bolt;
wherein the first support is connected to a main differential mechanism housing by a bolt;
wherein the first small sun gear is fixed to an axle housing by a bolt;
wherein the first planet carrier and the second planet carrier are connected into a whole by a spline hollow shaft;
wherein the second planet carrier and an outer ring of the first overrunning clutch are connected into a whole by a bolt;
wherein the inner ring of the first overrunning clutch and an input end of the clutch are connected together by a spline so as to control the rotational speed of the right wheel to be not lower than the set minimum rotational speed nmin;
wherein the second small sun gear is fixed to the axle housing by a bolt;
wherein the second large sun gear and the second support are connected together by a bolt;
wherein the second support and an outer ring of the second overrunning clutch are connected into a whole by a bolt; and
wherein the inner ring of the second overrunning clutch and the input end of the clutch are connected together by a spline so as to control the rotational speed of the right wheel to be not higher than the set maximum rotational speed nmax.
