DRIVE MECHANISM FOR AUTOMATED GUIDED VEHICLE

Document Type and Number:

WIPO Patent Application WO/2011/090755

Kind Code:

A3

Abstract:

A drive mechanism for an AGV that includes a drive unit for propelling the AGV and a steering unit for steering the AGV. The drive unit has a drive motor, drive transmission, and a drive wheel. The steering unit has a steering motor. Both motors are fixedly mounted on the AGV and remain stationary relative to each other while the drive motor rotates the drive wheel and the steering motor steers the drive wheel. The drive transmission couples the drive motor to the drive wheel and can be at least partially mounted within a gear housing that is rotatably mounted via a bearing so that the drive motor can be operated to move the AGV via power transferred to the drive wheel via the drive transmission, and the steering motor can be operated to steer the drive wheel by rotation of the gear housing and drive wheel via the bearing.
