Abstract
A single chain drive is disclosed that includes a drive sprocket, a drive motor, idler sprockets, front and rear axle sprockets, and a single chain. The drive motor rotates the drive sprocket, which rotates the idler sprockets, which rotate the single chain, which rotates the front and rear axle sprockets. The drive sprocket can be a lantern gear with covers, and pins that connect the cover, and the idler sprockets can have teeth that mesh with the pins between the covers of the drive sprocket. A drive shaft can couple the drive motor and drive sprocket, and an integrated parking brake can prevent rotation of the drive shaft when engaged. A chain case with lubricant can enclose the drive sprocket, idler sprockets, chain, and axle sprockets. The drive sprocket, idler sprockets and axle sprockets can be sized to provide a desired gear reduction.
