Non binding power actuator drive assembly

摘要: A drive assembly for a toothed rack and channel track type of power liftgate attaches the lift rod to indirectly, through shoe-yoke that transfers axial loads, but isolates from non reactive loads transferred rod. rigid yoke fits closely within axially spaced ends notch in rack, has clearance elsewhere outside rack. The is surrounded by shoe, which provides close fitting, slidable bearing layer with inside track, maintaining clearance. maintenance yoke-rack prevents transmission undesired back yoke.
