HUBS INCORPORATINP A VARIABLE RATIO TRANSMISSION SYSTEM 5 A HUB COMPRISES A CYLINDRICAL, 11011OW HUB MEMBER (2), WHICH IS MOUNTED TO ROTATE ABOUT ITS AXIS AND IN WHOSE INTERIOR IS A TRANSMISSION SYSTEM HAVING AN INPUT (I 0)@ WHICH IS 111OLIMCD TO ROTATE ABOUT THE AXIS, AN(] AN OUTPUT CONNECTED TO ROTATE WITH THE HUB MEMBER. THE TRANSMISSION SYSTEM COMPRISES FIRST AND 10 SECOND EPICYCLIC GEARSETS (14, 16). THE FIRST GEARSET (14) COMPRISES A FIRST SUN GEAR (181), WHICH IS MOUNTED TO ROTATE ABOUT THE AXIS AND IS IT) MESH WITH A I)ILII-.ILITV OF FIRST PLANET GEARS (20) MOUNTED TO ROTATE ABOUT RESPECTIVE PLANET SHAFTS (22) CARRIED BY A FIRST COMMON CARRIER (24), WHICH IS YHOUNTED TO ROTATE ABOUT (LIE FIRST AXIS. THE FIRST PLANET GEARS (20) ARE IN MESH WITH AN ANNULUS 15 GEAR (26) OR A FURTHER SUN GEAR (62). THE SECOND GEARSET (16) COMPRISES A SECOND SL111 GEAR (28), WHICH IS MOLINTED TO ROTATE ABOUT THE AXIS AND IS IN MESH WITH 11 PLINALITY OF SECOND PLANET -CARS (30) MOUNTED TO ROTATE ABOUT RESPECTIVE PHINCT SHAFTS (32) CARRIED BY A SECOND COMMON CARRIER (34). THE SECOND PLANET GEARS (30) ARE IN MESH WITH A SECOND ANNULUS GEAR (36). '['LIE FIRS( PLANET GEARS 20 (20) OR THE FIRST COMMON CARRIER (24) IS CONNECTED TO ROTATE IN S.YNCLUONISM WITH THE SECOND PLANET GEARS (30) OR THE SECOND COMMON CARRIER. THE FIRST AND SECOND SLIN GEARS (IS, 2S) ARE CONNECTED TO THE ROTORS (3S, 40) OF FIRST AND SECOND ELECTRIC MOTOR/GENCRATORS, RESPECTIVELY. THE POWER CONNECTIONS OF THE TWO STATORS (42, 46) ARE CONNECTED VIA A CONTROLLER (50) ARRANGED TO CONTROL THE 25 TRANSMISSION OL'POWER FROM ONE MOTOR/GENCRATOR TO THE OTHER. 3-@, '2
