FIELD: machine building.
SUBSTANCE: invention relates to device for changing of transmission ratio, particularly to gears with rolling engagement in toroidal track. Variator contains input disk (18, 20), installed rotary; output disk (22), installed rotary co-axial with input disk (18, 20); rollers (30, 32), by means of which it is passed rotation between input disk and output disk; pistons (36, 38) of double-acting, each of which interacts on corresponding one of rollers. Variator also contains levers (44, 60), each of which is connected to corresponding one of rollers (30, 32) and connected to it positioner (36, 38), influencing on roller for control of transmission ratio of variator.
EFFECT: creation of considerabl more packaged design of variator.
