Abstract

A device for continuously variable torque transmission belongs to the field of mechanical engineering and can be used to continuously vary the speed of rotation of the shaft (Sh) and torque. The device for continuously variable torque transmission consists of a housing 1, drive 2, driven 3, an auxiliary 4 and the other 5 Sh, a gear 6 is rigidly fixed on the drive Sh 2, which is engaged with a cylindrical toothed wheel (CTW) 7, rigidly fixed on one auxiliary Sh 4 and with a CTW 8 rigidly fixed on another auxiliary Sh 5, the axes of the differential pinions 9 and 10 are rigidly fixed on the auxiliary Sh 4 and 5, perpendicular to them, at the ends of which two cone-shaped toothed wheels (CSTW) 11 and 12 are freely fixed, which are in contact with the CTW of differentials 13, 14 and 15, 16 freely fixed on auxiliary Sh 4 and 5, one CSTW of the differential 13 on one auxiliary Sh 4 is rigidly connected to a CTW 17, which is freely fixed on the same Sh 4 and is in contact with a CTW 18, rigidly fixed on a flanged bush (FB) 19, freely fixed on the drive Sh 2, another CSTW 14 of the same differential is rigidly connected to a CTW 20, which is also freely fixed on this Sh 4 and which is in contact with a CTW 21 rigidly fixed on the driven Sh 3, on the other auxiliary Sh 5, one CSTW of the differential 15 is rigidly connected to a CTW 22, which is freely fixed on the same Sh 5 and is engaged with a CTW 23 freely fixed on a FB 19, another CSTW 16 of the same differential is rigidly connected to a CTW 24, which is freely fixed on the same Sh 5 and which is in contact with a CTW 21 rigidly fixed on the driven Sh 3, on a FB 19 between a CTW 18 rigidly fixed on a FB 19, and the flange of the FB 19, there is a sliding bush with a disc 25, into which the fork lever 26 enters, mounted on an axis 27 in the housing 1, moreover, there is a support bearing 28 between the fork lever 26 and a disk of the bush with a disk 25, levers 30 are installed diametrically opposite on the axes 29 in the flange of the FB 19, which touch the disk of the bush with a disk 25 with one end, and enter the holes of the CTW 23 with the other end, which is freely fixed on the FB 19, at the same time, springs 31 are installed between the ends of the levers 30 touching the disk of the bush with a disk 25 and the flange of the FB 19.

A device for continuously variable torque transmission comprising a housing, a drive shaft, a driven shaft, and at least first and second auxiliary shafts, wherein a gear is rigidly fixed on the drive shaft, the gear being engaged with a first cylindrical toothed wheel, the first cylindrical toothed wheel being rigidly fixed on a first auxiliary shaft, the gear being engaged with a second cylindrical toothed wheel rigidly fixed on the second auxiliary shaft, wherein axes of differential pinions are rigidly fixed on the first and second auxiliary shafts and are oriented perpendicularly to the first and second auxiliary shafts, wherein ends of the first and second auxiliary shafts include two cone-shaped toothed wheels freely mounted thereto, the two cone-shaped toothed wheels being in contact with cone-shaped toothed wheels of differentials freely mounted on the first and second auxiliary shafts, wherein a first cone-shaped toothed wheel of a first differential on the first auxiliary shaft is rigidly connected to the first cylindrical toothed wheel, the first cylindrical toothed wheel being freely mounted on the first auxiliary shaft and being in contact with another cylindrical toothed wheel rigidly fixed on a first flanged bush freely mounted on the drive shaft, wherein a second cone-shaped toothed wheel of the first differential is rigidly connected to the first cylindrical toothed wheel freely mounted on the drive shaft and in contact with another cylindrical toothed wheel rigidly mounted on the driven shaft, wherein on the second auxiliary shaft, the second cone-shaped toothed wheel of a second differential is rigidly connected to a cylindrical toothed wheel freely mounted on the drive shaft and engaged with another cylindrical toothed wheel freely fixed on a second flanged bush, wherein another cone-shaped toothed wheel of the second differential is rigidly connected to the second cylindrical toothed wheel freely mounted on the drive shaft and which is in contact with the second cylindrical toothed wheel rigidly mounted on the driven shaft, on the second flanged bush, wherein between the second cylindrical toothed wheel rigidly mounted on the second flanged bush, and the flange of the second flanged bush, a sliding bush with a disc is disposed, wherein a fork lever enters into the sliding bush with a disc, wherein a support bearing is mounted on an axis in the housing between the fork lever and the disk of the bush with a disk, levers are installed diametrically on opposite sides of axes of the flange of the flanged bush, wherein the levers contact the disk of the bush with a disk with one end, and enter holes of the second cylindrical toothed wheel with another end, the second cylindrical toothed wheel being freely fixed on the second flanged bush, and wherein springs are installed between the ends of the levers that contact the disk of the bush with a disk and the flange of the second flanged bush.
