摘要： An automatic transmission system for a vehicle having a plurality of drive gears mounted on an input shaft, a plurality of driven gears mounted on an output shaft and meshing with the drive gears, a torque converter disposed between a crankshaft of an engine and the input shaft, synchromesh mechanisms for synchronously engaging the drive gears with the driven gears and a shift controller for automatically actuating the synchromesh mechanisms so as to obtain a required gear ratio, includes a lock-up clutch incorporated in the torque converter for connecting a turbine shaft of the torque converter with the crankshaft, an electronically controlled throttle valve for automatically operating to reduce a rotation speed of the crank shaft when the gear is shifted, a bypass clutch for transmitting torque from the input shaft to the output shaft when the gear is shifted while the electronically controlled throttle valve operates to reduce a rotation speed of the crankshaft, an input clutch provided between an output element of the torque converter and the input shaft for selectively controlling a torque transmission from the crankshaft to the input shaft when the gear is shifted, and a brake mechanism provided on an impeller shell of the torque converter for additionally reducing a rotational speed of the crankshaft while the electronically controlled throttle valve operates to reduce a rotational speed of the crankshaft.

摘要： Vehicle automatic transmission system having input shaft drive gears, output shaft driven gears meshing with the drive gears, a torque converter disposed between an engine crankshaft and the input shaft, synchromesh mechanisms for synchronously engaging the drive gears with the driven gears and a shift controller for automatically actuating the synchromesh mechanisms to obtain a required gear ratio. A lock-up clutch is incorporated in the torque converter for connecting a turbine shaft of the torque converter with the crankshaft. An electronically controlled throttle valve automatically operates to reduce crank shaft rotation speed when the gear is shifted, a bypass clutch transmits torque from the input shaft to the output shaft when the gear is shifted while the electronically controlled throttle valve reduces rotation speed of the crankshaft, and an input clutch selectively controls torque transmission from the crankshaft to the input shaft when the gear is shifted.
