Shaft 7 of carrier 33 with two position gear rim is arranged coaxially to shaft 5 and shaft 6. Third tubular shaft 11 of housing of epicyclic wheel with gear rim 38 is freely fitted on shaft 7. Output shaft 8 with hub of three-position shifter sleeve 40 is arranged coaxially to shaft 7. Sleeve 40 is movably coupled by guide 41 with two-rim shifter sleeve 42 arranged between gear rim 37 of housing 36 of epicyclic wheel 32 and gear rim 43 of gearbox case provided with two inner gear rims and one outer gear rim.

EFFECT: perfected design owing to reduction of metal usage and complexity.

SUBSTANCE: continuously variable transmission comprises housing, input and output shafts, reverse mechanism and multi-disk planet variator provided with planet reduction gear, which define a variator. The solar pinion of the reduction gear is fit on the output shaft with interference and its epicycle is secured to the housing of the transmission. The variator has epicycle mounted in the housing of the transmission and made of a stack of disks and solar pinion made of a disk stack mounted on the output shaft of the variator connected with the output shaft of the reverse mechanism. The carrier of the variator is connected with the carrier of the planet reduction gear and consists of two disks interconnected by means of tension bolts. The disks of the carrier have shaped slots the number of which is equal to the number of axles mounted in the shaped slots for permitting change of position and interaction with the disks of the solar pinion and epicycle. The gear ration controller is build in the carrier of the variator. The planet reduction gear, planet multi-disk variator, and reverse mechanism are axially aligned.

EFFECT: prolonged service life and expanded functional capabilities.

SUBSTANCE: planet friction variator comprises shaft (1), solar wheel (2), corona wheel (6), carrier (4) with satellites (3), and secondary shaft (5). Corona wheel (6) that is used as a control member is connected with variator housing (11) and primary shaft (1) through friction mechanisms. Secondary shaft (5) is made in block with carrier (4) for permitting control of velocity and direction of rotation of the corona wheel by means of friction mechanisms and control electric motor (9) connected with the corona wheel.

EFFECT: simplified structure, reduced sizes, and enhanced reliability.
