Abstract
A hybrid electromechanical transmission for a tracked vehicle includes a drive motor and a steer motor with separate propulsion paths to output members of the transmission. A two-speed range package is provided, including an input planetary gear set and first and second clutches. The first and second clutches are selectively alternatively engagable to establish two speed ratios between the drive motor and the remainder of the transmission. Additionally, the drive motor and the steer motor are preferably designed with a module construction, allowing for easy connection and removal for serviceability via the use of axial V-clamps.
