Abstract:
1. A driven wheel suspension system for a vehicle having a chassis suspended from a driven wheel, including: a suspension mechanism including a driven wheel carrier member rotatably connected to the driven wheel, the suspension mechanism configured to isolate the movement of the driven wheel from the movement of the chassis, the driven wheel movable a distance relative to the chassis which defines a suspension travel; a drivetrain including a looped power transmission element configured to transmit power between the driven wheel and a power source mounted on the chassis; and an idler member rotatably mounted on an idler carrier member that is movable relative to both the chassis and driven wheel carrier member, said idler member configured to engage with a power transmitting segment of the looped power transmission element and move to follow a predetermined path as a function of suspension travel, to thereby alter a path of said power transmitting segment of the looped power transmission element, wherein, altering the path of said power transmitting segment of the looped power transmission element results in a lengthening or shortening of the power transmitting segment of the looped power transmission element.
