The present invention relates to an automatic gearbox comprising at least a drive transmission assembly. The drive transmission assembly comprises an active shaft (1100a) rotatable in a predetermined direction, an intermediate shaft (1200a), and a passive shaft (1300a). A connecting rod (1150a) is connected in a rotatable manner at its one end to the active shaft (1100a) and at its other end to the intermediate shaft (1200a). The connecting rod (1150a) is adapted to transmit rotary motion of the active shaft (1 100a) to the intermediate shaft (1200a) so that the intermediate shaft (1200a) is rotatable in two different directions in a predetermined angle. The drive transmission pairs connect the intermediate shaft (1200a) and the passive shaft (1300a) so as to transmit rotary motion of the intermediate shaft (1200a) to the passive shaft (1300a). The drive transmission pairs are adapted in a way that they' are only in the drive transmission state when the intermediate shaft (1200a) rotates in a predetermined direction. |
