Automatic transmission gear for front-drive car

Abstract

Abstract PURPOSE:To aim at making a transmission gear with small size by such a construction that the torque converter side bearing to bear the output gear is smaller than the transmission geat side bearing as well as helical gear is adopted for the output gear to allow thrusting force to act on the transmission gear side. CONSTITUTION:Of two bearings 60, 61 arranged symmertically at the right and left sides of output gear 47, the bearing 60 situated nearer the torque converter 2 shall be chosen small so as to make small the outside dimension of the bearing's housing 1a, which is arranged inside the concave 2e provided at the center of tprque converter 2. Thus the spacing between torque converter 2 and output gear 47 can be small while the capacity of the bearing 61 situated nearer the transmission gear can be chosen large as it has spacy margin in the perpheral direction. Because a helical gear is employed for output gear 47 so that the thrust A yielded at the time of forward driving is born by the bearing 61, which has larger capacity, the dimension of this automatic transmission gear can be made small.
