Drive train assembly for use in powered vehicles or trailers

A drive train assembly for use in powered vehicles or trailers, said drive train assembly adapted to provide power to a first wheel assembly, said drive train assembly comprising:

• an input shaft having a fixed gear assembly, said input shaft adapted to be rotatably coupled to a source of motive power, said input shaft being rotatably coupled to said source of motive power through a gear box, said fixed gear assembly being rotatable with said input shaft;
• a helical drive adapted to rotate about said input shaft and having a first side gear and a second side gear located on opposite sides thereof, said first side gear being located adjacent said fixed gear assembly;
• a drive disconnect gear assembly adapted to rotate about said input shaft and including two gear discs fixed to each other and extending in opposite directions, one said gear disc adapted to engage said second side gear and the other gear disc adapted to engage a thru-shaft gear to provide power to a second wheel assembly;
• a clutch collar slidable from a first to a second position, wherein in said first position said clutch collar engages said fixed gear assembly and wherein in said second position said clutch collar engages both said fixed gear assembly and said first side gear;
• wherein when said clutch collar is in the first position the input shaft is decoupled from the wheel assembly;
• and
• wherein when in the second position the clutch collar thereby causes any rotational motion of the input shaft and the fixed gear assembly to be transferred to the drive disconnect gear assembly and to the wheel assembly.
