Vehicular transmission shift mechanism

Patent ·
OSTI ID:6362986

This patent describes a vehicular transmission having a main speed change mechanism and a sub speed change mechanism both housed within a transmission case. The main speed change mechanism has gear trains in plural shifting stages provided between input and output shafts and capable of being established selectively and also has a plurality of synchronizing mechanisms operable by shift forks to establish the gear trains selectively. The sub speed change mechanism has a reduction gear train for obtaining a still lower speed than the lowest shifting stage in the main speed change mechanism and also has a sub speed gear shifting synchronizing mechanism operable by a sub speed gear shift fork to establish the reduction gear train. This sub speed change mechanism is disposed in parallel with the main speed change mechanism, the sub speed gear shift fork having means connected to one end of a lever pivotably supported at an intermediate part thereof by a pivot pin, the pivot pin being mounted on the transmission case from the outside thereof.
