Title:
CLUTCH VALVE APPARATUS FOR STATIC HYDRAULIC TYPE CONTINUOUSLY VARIABLE TRANSMISSION
Document Type and Number:
Japanese Patent JPS61278654
Kind Code:
A
Abstract:
PURPOSE:To carry out connection and disconnection of power without generating shock by installing a clutch valve for the communication and cut-off between the high-pressure and low-pressure passages contiguously to the cylinder hole group of a hydraulic pump and gradually increasing the communication opening degree. CONSTITUTION:The first and the second valve boards 14 and 15 are installed between a pump cylinder 7 and a motor cylinder 8, and a clutch valve 50 which communicates to an annular low-pressure passage 41 and a high-pressure passage 40 is installed. The clutch valve 50 is turned-ON/OFF through a clutch control ring 54 and a spring 55, and at the intermediate position of the clutch control ring 54, the opening degree of the horizontal hole 53 of the clutch valve 50 is properly throttled, and a hydraulic motor M can be set into a semiclutch state. Therefore, the excessive operation can be obtained smoothly.
