DEVICE FOR CONTROL OVER VEHICLE INFINITELY VARIABLE TRANSMISSION Russian patent published in 2014 - IPC F16H61/04 F16H37/02 F16H61/16 

FIELD: transport.

SUBSTANCE: proposed device comprises infinitely variable transmission mechanism, extra transmission module, transmission control module and module to set target overload torque at stoppage. Infinitely variable transmission mechanism allows a continuous variation of gear ratio. Extra transmission mechanism is mounted serially with infinitely variable transmission to be changed over between 1^st and 2^nd gears. Transmission control module can stop transport facility to retain extra transmission gear at 2^nd gear position at stoppage. Aforesaid module to set target overload torque sets target overload torque of friction engagement element on the side of engagement of multiple friction engagement elements equal to initial overload torque.

EFFECT: improved characteristics.
