Abstract:
1. A transmission assembly for a power tool comprising: an input shaft; a first driving gear coupled to the input shaft for co-rotation therewith; an output shaft having a first driven gear continuously engaged with the first driving gear; a first transmission path comprising a high speed transmission path; a second transmission path comprising a low speed transmission path; a controller for one of engaging and disengaging the high speed transmission path; and a clutch for enabling the low speed transmission path to operate at a lower speed than an output of the transmission assembly when the high speed transmission path is engaged, wherein torque from the input shaft is transferred through the first driven gear when the high speed transmission path is engaged, and wherein the first driving gear is coupled to the input shaft for co-rotation therewith in both the high speed and low speed transmission paths.
