ABSTRACT:
A transmission has a drive gear shaft disposed coaxially with an input shaft which extends in parallel with an output shaft. Two pairs of meshing gears, one of which constituting a gear train of high speed gear ratio while the other constitutes a gear train of low speed gear ratio, are arranged for the torque transmission from the input shaft to the drive gear shaft. The drive gear shaft is connected to the output shaft through a plurality of meshing speed gear pairs such as first gear pair, second gear pair, third gear pair and fourth gear pair, as in the ordinary transmission. In operation, one of the gear trains of the high speed and low speed gear ratios is selectively engaged, so that each of the speed gears may be operated at either the high speed range or the low speed range. The transmission is small-sized, light weight and less expensive, thanks to the coaxial arrangement of the input shaft and the drive gear shaft and, therefore, can suitably be used in small-sized vehicles having limited installation space preserved for the transmission.
