Transverse type automatic transmission with intermediate power transfer through lay shaft
An automatic transmission is described for an automotive vehicle, which consists of: a. a fluid torque converter, comprising a converter rotational power input member and a converter rotational power output member, the converter rotational power output member, the converter rotational power output member and the converter rotational power output member both being rotatable about a first axial line; b. a first gear transmission mechanism, comprising a first transmission rotational power input member, and a first transmission rotational power output member, and being adapted to be selectively controlled to produce any one of speed ratios between the first transmission rotational power input member and the first transmission rotational power output member; c. a through lay shaft which extends along and is rotatable about a second axial line parallel to the first axial line and displaced laterally therefrom; d. a second gear transmission mechanism supported by the through lay shaft to be rotatable about a second axial line; e. a rotational power transfer mechanism for transferring rotational power between the first transmission rotational power output member and the through lay shaft, including a first rotational member rotatable about the first axial line and rotationally coupled with the first transmission rotational power output member and a second rotational member rotatable about the second axial line and supported and rotationally coupled with the through lay shaft; and f. a power output gear wheel rotatable about the second axial line and rotatably supported by the through lay shaft and rotationally coupled with the second transmission rotational power output member.
