Abstract: A continuously variable transmission system for a hybrid vehicle is described. The system includes a belt-type continuously variable transmission that is adapted to receive torque from more than one power source. The belt-type continuously variable transmission includes a plurality of pulley sets, which are operatively connected by means of a belt extending over width-variable grooves defined between halves of the pulley sets. The belt is held in position by means of belt tightener. More than one pulley sets are adapted to act as drive pulleys for independently receiving torque from the power sources, whereas at least one pulley set is adapted to act as driven pulley for receiving the torque from the drive pulleys and transmitting the torque to a set of drive wheels for running the vehicle.

Abstract: A toroidal type continuously variable transmission system is disclosed. The system comprises a plurality of input disks (124 & 126) and at least one output disk (128), which are arranged noncoaxially; and a plurality of tiltable rollers (136, 138 & 140) for operatively coupling the input disks (124 & 126) and the output disk (128) for transmitting the torque. The transmission system is adapted to be operated by the torque transmitted by at least one of the plurality of input disks (124 & 126) to the at least one output disk (128).

Abstract: A transmission system (100) for vehicles comprising at least one set of plurality of input shafts (110 & 116) disposed concentrically and having an exposed portion; clutch means (108 & 114) at one end of the input shafts for connecting the input shafts to power sources; an output shaft (118) in communication with the input shafts for conveying the power to set of wheels; input gears (102 & 104) arranged in spaced parallel disposition on the exposed portion of the input shafts; dog clutch means (124 & 126) disposed between the input gears for locking the input shafts to respective input gears; and plurality of drive gears (120) arranged in spaced parallel disposition on the output shaft (118) for engaging in drive relation with the input gears, where the drive gears are configured to transmit power to the output shaft from the input shafts by means of the input gears.
