A method for realizing stepless speed change of a continuously variable transmission of a motor vehicle according to claim 1, characterized in that: power is input to a power input shaft (4) to drive a unidirectional rotation chain gear (5-1) and a unidirectional chain (6) to directionally rotate, the unidirectional chain (6) drives the unidirectional rotation chain gear (5-4) and the unidirectional rotation chain gear (5-2) to rotate, the unidirectional rotation chain gear (5-2) drives the unidirectional rotation chain gear (5-3) to rotate through a rotating shaft (16), the unidirectional rotation chain gear (5-3) drives a unidirectional die change chain (9) to rotate, the unidirectional die change chain (9) drives a die change gear arm (10) to rotate around a power output shaft (14) to finish power output, when speed is changed, a hydraulic rod (8) pushes a hydraulic slide block (7) to move towards the power input shaft (4) and drives the unidirectional rotation chain gear (5-2) and the unidirectional rotation chain gear (5-3), the unidirectional rotating chain gear (5-3) can stretch the unidirectional variable-die chain (9), the unidirectional variable-die chain (9) can extrude variable-die tooth arms (10), supporting arms (11) and springs (12), the number of chain buckles of the unidirectional variable-die chain (9) connected between two adjacent variable-die tooth arms (10) is unchanged during the period that the two groups of variable-die tooth arms (10) operate for one circle, the distance between two sliding teeth (19) can be shortened, the distance difference is buffered by a strong spring (22), the maximum travel of the sliding teeth (19) and the rotating speed of a power output shaft (14) determine the maximum moving speed of a hydraulic sliding block (7), and the non-contact chain part of the variable-die tooth arms (10) and the supporting arms (11) is controlled by an annular limiting chain (13) and is kept to be in an annular shape, so that the stepless speed change of the motor vehicle is.
