Title: Automatic transmission apparatus

Abstract

An automatic transmission apparatus is described comprising: an input shaft, an output shaft disposed behind and coaxially with the input shaft, a counter shaft disposed substantially parallel to both of the input and output shafts, a first gear train including a first gear provided on the input shaft and a second gear provided on the counter shaft to be meshed with the first gear so as to form a first power transmitting path, first friction clutch means operative selectively to make and break the first power transmitting path, a second gear train including a third gear provided through one-way clutch means on a rear end portion of the input shaft and a fourth gear provided on the counter shaft to be meshed with the third gear so as to form a second power transmitting path, second friction clutch means provided at a front end portion of the output shaft, a third gear train including a fifth gear provided on a rear end portion of the counter shaft and a sixth gear provided on the output shaft to be meshed with the fifth gear so as to form a fourth power transmitting path, third friction clutch means operative selectively to makemore » and break the fourth power transmitting path, fourth friction clutch means operative selectively to make and break the second power transmitting path, a fourth gear train including a seventh gear provided on the counter shaft and an eighth gear provided on the output shaft and fifth friction clutch means operative selectively to make and break the fifth power transmitting path.« less
