Abstract

PURPOSE: To promote the reduction of synchronizing time of a subtransmission, by connecting a small contour transmission member of a hydraulic clutch to the side of an input shaft.
CONSTITUTION: A hydraulic clutch C, which controls disc plates 25, 26 being forced to come into press contact by a pressure of oil, exists interposing between an output shaft 8 from a main transmission A of gear type, operating a speed change control by the action of an oil hydraulic actuator, and an input shaft 9 for a subtransmission B of gear type operating a speed change control by the action of an oil hydraulic actuator. While the hydraulic clutch C operates so as to perform the disconnecting action immediately before both the actuators are actuated. In this transmission, a small contour transmission member 23 of the hydraulic clutch C is connected to a side of the input shaft 9. By this constitution, synchronizing time of the subtransmission can be reduced.
