IPC: F16H61/06
Filed: 1989-01-31
Abstract: PURPOSE:To suppress a speed change shock by providing a pressure sudden increase-moderating accumulator to be interposed between a control valve and a hydraulic clutch and increasing a pressure slowly over three steps moderately connecting the hydraulic clutch. CONSTITUTION:A speed change valve 65 is selected, for instance, when a pressure is introduced to a 3-speed hydraulic clutch 22a, the pressure is introduced also to a pressure oil receiving chamber 97 in an accumulator 93, lifting a piston 95 against a spring 96, and the pressure in the clutch 22a slowly rises. When a drain port 98 communicates with small contour part space 99 by moving the piston 95, pressure oil is discharged through an orifice 95d performing more slowly a pressure rise. When the drain port 98 is closed by a land 95a by further movement, the pressure rises to a degree equal to the increasing speed of the first step while compressing the spring 96, and when the piston 95 is adapted to a compression end of the spring 96, the pressure in the hydraulic clutch 22a suddenly rises. Thus, a starting and speed change shock can be decreased.
