FIELD: machine building.
SUBSTANCE: invention refers to machine building and can be used in transmissions of vehicles. The disk planetary stepless transmission consists of external central friction disks (2) secured on case (1), of internal central friction disks (4) secured on input shaft (5) of the stepless transmission, and of intermediate conic friction disks-satellites (3) rotating on pivot arms (6) and fixed on driver (9), also one of the groups of ends of pivot arms is equipped with pushers (11); the said pushers interact with working surface of variable geometry. Working surface of variable geometry is made in form of internal surface of one or several rows of stops (20, 21) arranged in axial direction; also all stops (20, 21) are kinematically tied between them and with the case of the stepless transmission.
EFFECT: upgraded working characteristics of disk planetary stepless transmission.
