ABSTRACT:
A friction drive wheel, particularly for obtaining a rotary drive for a hydraulic pump or electrical dynamo on a pipeline inspection pig, has a hub with a central hole and keyway for mounting on a axle. Attached to the hub is a rim in which are mounted bundles of bristles in ferrules. The bundle axis is at an acute angle to the radius of the wheel so that the bristles will act as a leading strut. A flange stop may be provided to limit deflection of the bristles.
