SWITCHING DEVICE FOR TWO-WHEEL DRIVE AND FOUR-WHEEL DRIVE, AND DRIVE ACTUATOR THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide an actuator at a low cost by constituting a pair of cam followers with a simple constitution, and to provide the cam followers capable of easily changing working torques of the cam followers working on respective driven shafts corresponding to working loads of the respective driven shafts. SOLUTION: This actuator has two driven shafts which are disposed parallel to each other in an axial direction so as to freely travel, and cams for driving the driven shafts respectively attached to the respective driven shafts. This actuator in which the respective cams are driven to prescribed stop positions respectively preset corresponding to modes by switching operations of an operation switch having a plurality of switching modes to selectively move the respective driven shafts to prescribed strokes in the axial direction has a rotating plate which is fixed at an output shaft of the actuator, integrally rotated with the output shaft, and a pair of rollers which are respectively distant at a prescribed distance in the radial direction from the rotational center of the rotating plate. The cam followers drive the cams by respectively engaging the pair of the rollers with the respective cams. COPYRIGHT: (C)2004,JPO
