<p>The present invention relates to a transmission and, more particularly, to a transmission for shifting gears without a clutch. An aspect of the present invention includes: an input shaft where a first input shaft gear and a second input shaft gear are disposed; a torque converter unit that has a turbine which rotates by converting an input shaft torque; an input carrier that is disposed so as to be coupled with the turbine and revolve around the input shaft and has a first transmission gear which is engaged with the first input shaft gear; a drive shaft ring gear that is engaged with the first transmission gear; a drive carrier that is connected with the drive shaft ring gear and has a first differential gear and a second differential gear which is engaged with the first differential gear; an output shaft where an output ring gear that is engaged with the second differential gear is disposed; a fixed carrier that is fixed to a housing of the torque converter unit and has planetary gears which are engaged with the second input shaft gear; a first unilateral bearing the outer side of which is disposed so as to be fixed to the fixed carrier and the inner side of which is provided so as to be capable of rotating only in a single direction; a first adjustment gear that is disposed so as to be fixed to an inner side of the first unilateral bearing and is engaged with the first differential gear; a ring gear-shaped transmission gear that is engaged with the planetary gear; a second unidirectional bearing the outer side of which is disposed so as to be fixed to the transmission gear and the inner side of which is provided so as to be capable of rotating only in a single direction; a second adjustment gear that is disposed so as to be fixed to an inner side of the second unidirectional bearing and is engaged with the first differential gear; a third unidirectional bearing the inner side of which is fixed to the input shaft and the outer side of which is provided so as to be capable of rotating only at or below an input speed of rotation; and a third adjustment gear that is coupled with an outer side of the third unidirectional bearing and is engaged with the second differential gear.</p> |
