Abstract

PURPOSE:To control finely the changeover of plural a clutches, by providing a fluid type double-acting actuator, and controlling the pressure on the drain side by a hold valve, etc. CONSTITUTION:A first input shaft 2 and a second input shaft 3 are situated on a driving shaft 1b connected with an engine 1, and are connected to the driving shaft 1b by clutches 5, 6. The clutches 5, 6 are actuated by the first and second double-acting fluid type clutch actuators 8, 10 through operation levers 7, 9. In this case, the fluid pressures acting on pressure receiving surfaces 8a, 10a of the pistons of the actuators 8, 10 are controllled independently by first and second controlling electromagnetic valves 35, 36. On the other hand, the fluid pressures acting on the pressure receiving surfaces 8b, 10b are controlled by a common hold electromagnetic valve 54, and valves 35, 36, 54 are controlled by a control circuit 64.
