1. A power transmission system for vehicles including a main drive wheel and an auxiliary drive wheel, the system comprising:
- a main power transmission system configured to transmit main drive power to the main drive wheel via a first train of torque transmitters; and
an auxiliary power transmission system configured to transmit auxiliary drive power from an electric motor to the auxiliary drive wheel via an interruptive second train of torque transmitters including;
a differential;
a combination of a plurality of reduction gears and a clutch disposed between the electric motor and the differential;
a casing configured to accommodate the differential, a plurality of gear stages of the plurality of reduction gears and the clutch; and
a seal disposed between the casing and a power transmission member provided through the casing,wherein the clutch is disposed in opposition to the electric motor relative to the plurality of reduction gears.
