Abstract:

A conveyor assembly is for use with a vehicle having a wheel pivotable about an axis and an actuator configured to pivot the wheel. The conveyor assembly includes a carriage connectable with the vehicle and having a wheel pivotable about an axis, a swing axis and a first bearing surface about the swing axis. A carriage steering actuator pivots the carriage wheel about its axis in one direction when the vehicle actuator pivots the vehicle wheel about its axis in an opposing direction. A conveyor connected with the carriage has a second bearing surface engaged about the first bearing surface. Further, a swing actuator rotates the conveyor about the swing axis such that the second bearing surface linearly displaces along a first arcuate path as an actuator end displaces along a second arcuate path, configured such that the bearing surface displacement is greater than the actuator end displacement.
