Title:
HYDRAULIC ACTUATOR
Document Type and Number:
Japanese Patent JPS61140628
Kind Code:
A
Abstract:
PURPOSE:To prevent the malfunction due to the centrifugal oil pressure in a hydraulic servo by providing the opening of an oil passage to open on the outer circumferential side of a hydraulic servo and keeping operating oil from remaining in the hydraulic servo when draining oil in the hydraulic servo. CONSTITUTION:When a multiple disk clutch is released, the power transmitted to a right case 424 is not transmitted to a left differential case 511. Whenthis multiple disk clutch is released, an oil passage 614 is provided to open in the outer circumferential position in a hydraulic servo C-4 so that the supply and drainage of operating oil is performed on the outer circumferential side of the hydraulic servo C-4 and that the operating oil in the hydraulic servo C-4 is drained from the oil passage 614 opened on the outer circumference not to remain in it, and consequently the malfunction of the hydraulic actuator due to the centrifugal oil pressure of the remained oil does not occur.
