Abstract
PURPOSE: To suppress useless clutch slip during acceleration with little shock by varying the oil pressure increasing characterisitc, in response to acceleration and deceleration of a hydraulic clutch type speed change gear.
CONSTITUTION: In the contracted oil passage 21 for allowing the hydraulic pressure in a clutch oil feeding circuit 4 to operate slowly in the back space a control piston 18, a hydraulic accumulator 23 is installed, being connected to said passing 21 at the stage behind the contracted part 21a in the circuit 21. The unload valve 32 which can unload the hydraulic pressure in the hydraulic chamber of the said hydraulic accumulator 23 is installed, and the unload valve 32 is operated in unloading action once in deceleration phase and the action of the hydraulic accumulator 23 is made avilable. In acceleration phase the unload valve 32 is made inoperative, and the accumulator 23 is cut-off from operation. Thus, hydraulic pressure rise is achieved comparatively fast in acceleration phase ad useless clutch slip can be suppressed.
