<p>Disclosed is a transmission device for a vehicle. According to an embodiment of the present invention, the transmission device for a vehicle comprises: two input shafts arranged on a coaxial line without interfering with each other to input rotatory power of a power source through the respective clutches, and respectively includes a plurality of input gears; two output shafts arranged on the input shafts in parallel, includes a plurality of forward speed gearshifts which are respectively circumscription-engaged with the input gears on the two input shafts, and synchronization units which are respectively synchronized-connected to the forward speed gearshifts, and respectively have an output gear which is circumscription-engaged with each of the final reduction gears; and backward transmission means which are respectively arranged on the input shafts in parallel, includes two backward shafts which are mutually power connected and respectively includes backward gears to be respectively circumscription-engaged with the input gears on one input shaft and the other input shaft which reverse-rotation transmits the rotary power of the power source from one input shaft to the other input shaft by the operations of the synchronization units, wherein a backward transmission terminal is realized by reverse-rotation reduction outputting the rotatory power of the power source which is normal-rotation inputted from one input gear on one of the two input shafts by an operation of the corresponding synchronization unit through the backward transmission means, one input gear on the other input shaft, the forward speed gearshift mounted on one output shaft to be circumscription-engaged with one input gear on the other input shaft, one output shaft, and the final reduction gear circumscription-engaged with the output gear on one output gear.</p> |
