Automatic transmission for motor vehicles

摘要

An automatic transmission for F.F. (front engine-front drive) type motor vehicles, in which a hydraulic torque converter and an auxiliary transmission mechanism are successively coupled with an output shaft of a transversely mounted internal combustion engine with its rotational axis disposed widthwise of the vehicle, and the rotational axis of a main transmission mechanism is disposed parallel with the rotational axis of the auxiliary transmission mechanism, the input shaft of the main transmission mechanism being rotationally coupled with the output shaft of the auxiliary transmission mechanism. The output shaft of the main transmission mechanism is rotationally coupled with a differential gear device which has its output shafts rotationally coupled with front wheel axle shafts. The auxiliary transmission gear mechanism constitutes an overdrive or an underdrive (reducing) mechanism.
