Automobile transmission with output shaft parallel to crank shaft and parking gear fixed to the output shaft
A driving device is described for an automobile having axles, driving wheels supported by the axles and an engine located proximate the driving wheels, having a crankshaft disposed substantially parallel to the axles supporting the driving wheels, the device comprising: a fluid-type torque converter having coaxial input and output members and disposed on one axial side of the engine connected to and coaxial with the crankshaft; an auxiliary speed change gear assembly having coaxial input and output members and disposed on one axial side of the torque converter remote from the engine with the input member connected to and coaxial of the torque converter; the output member of the auxiliary speed change gear assembly is provided in the shape of a gear; a transmission shaft disposed substantially parallel to the auxiliary speed change gear assembly; a driven gear having a disc portion and toothed peripheral portion; a drive gear drivingly connected to the other end of the transmission shaft closer to the torque converter than the one end of the transmission shaft; a final reduction gear disposed between the driving wheels to be in meshing engagement with the drive gear to transmit power to the axles; a parking gear comprising an annular gear element fixed by bolts proximate the toothed peripheral portion to the axial side surface from which the transmission shaft extends toward the other end. The parking gear is supported by the disc portion for rotation with the driven gear; and means for selectively engaging the parking gear to prevent rotation of shaft when automobile is in parking condition.
