Abstract:
A power transmission comprising:a transmission housing; an input shaft rotatably supported in said housing; an output shaft rotatably supported in said housing; a first simple planetary gear set having a first sun gear member, a first ring gear member, and a first planet carrier assembly member, said ring gear member being continuously connected with said output shaft; a second simple planetary gear set having a second sun gear, a second ring gear, and a second planet carrier assembly member, said second ring gear member being continuously connected with said first planet carrier assembly member, and said second sun gear member being continuously connected with said transmission housing; a first selectively engageable clutch operatively connected between said input shaft and said first sun gear member; a second selectively engageable clutch operatively connected between said input shaft and said first planet carrier assembly member and said second ring gear member; a third selectively engageable clutch operatively connected between said first sun gear member and said second planet carrier assembly member; a fourth selectively engageable clutch operatively connected between said second planet carrier assembly member and said output shaft; a fifth selectively engageable clutch operatively connected between two members of said second simple planetary gear set; a first selectively engageable brake operatively connected between said first sun gear member and said transmission housing; and said five clutches and first brake being operatively engaged in combinations of two to establish five forward drive ratios and one reverse drive ratio between said input shaft and said output shaft.
