Patent ID: 7798261

Claim:
A tracked vehicle, comprising: a track module frame; at least two electrically driven track wheels connected with the track module frame, each electrically driven track wheel comprising: a driving track wheel having built in cogs on an outer surface for driving a track; a permanent magnet electric motor drive having a stationary mounting shaft running through the brushless DC motor for connecting the electrically driven wheel to a frame of the tracked vehicle, wherein the permanent magnet electric motor drive is coupled within the driving track wheel to develop rotational torque for rotating the driving track wheel; an internal direct drive pulse modulated DC integral motor to provide twice the power available to the ground and the actual tensile stress on the at least two flexible tracks is approximately evenly distributed; and two end plates covering each end of the driving track wheel enclosing the brushless DC motor therein, wherein the driving track wheel directly transmits thrust loads directly to the mounting shaft; at least two flexible tracks, one on each sides of the track module frame and being rotated by the at least two electrically driven track wheels, wherein the at least two flexible tracks have the ability to resiliently track uneven surfaces to increase track life and minimizing disturbance to the terrain; and a suspension system for connecting the track module frame to a chassis of the tracked vehicle, wherein shock encountered by the track module frame are not transmitted to the vehicle chassis.
