Variable transmissions with nested pulleys

A variety of transmission mechanisms are provided that include split pulleys nested within each other in order to reduce the size of the transmissions, to provide infinitely variable transmission ratios that include forward and reverse ratios, or to provide some other benefits. The transmissions include multiple inner split pulleys nested within an outer split pulley. Two, three, or more inner split pulleys can be disposed within the transmission to balance the mass of the inner split pulleys in order to reduce vibration and internal stresses experienced by the transmission. This can increase the lifespan of the transmission, reduce wear, and increase efficiency. Additionally, providing multiple inner split pulleys in a nested configuration can allow for reduction of loads transmitted through bearings of the transmission.

Control device of hybrid vehicle

A control device of a hybrid vehicle includes a pressing torque applying portion configured to control the first rotating machine to output a pressing torque acting in a predetermined backlash elimination direction in backlash elimination in which one of tooth surfaces of meshing gears is pressed against the other at a meshing portion during motor running, so that the pressing torque is applied on the electric transmission mechanism. When an electrical angle of the first rotating machine is within a predetermined electrical angle range in which a cogging torque of the first rotating machine generated in accordance with rotation of the first rotating machine is equal to or greater than a predetermined torque required for the backlash elimination in the predetermined backlash elimination direction, the pressing torque applying portion makes the pressing torque smaller as compared to when the electrical angle is outside the predetermined electrical angle range.

Cruise control method for hybrid vehicle
