Title:
HYDRAULIC CIRCUIT CONSTRUCTION IN SYSTEM FOR ADJUSTING RIGHT AND LEFT DRIVING FORCES FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/1993/007017
Kind Code:
A1
Abstract:
A hydraulic circuit construction in a system for adjusting right and left driving forces for a vehicle, which is used for adjusting the driving forces imparted to the right and left wheels in a motor vehicle and the like. This system for adjusting the right and left driving forces for a vehicle comprises a mechanism for controlling the transfer of the driving forces which system performs adjustment of the driving forces. This mechanism for controlling the transfer of the driving forces includes: a left wheel controlling hydraulic type torque transfer mechanism for transferring the driving force to a shaft of the left wheel or therfrom; a right wheel controlling hydraulic type torque transfer mechanism for transferring the driving force to a shaft of the right wheel or therefrom; and a hydraulic circuit for driving these hydraulic type torque transfer mechanisms. This hydraulic circuit may consist of: a hydraulic pressure regulating section (74) for regulating the hydraulic pressure from a hydraulic pressure source (73) and outputting it; hydraulic pressure input sections (20D, 20D) attachingly provided on the hydraulic type torque transfer mechanisms, for receiving hydraulic pressure for performing the torque transfer; and a change-over valve (76) included in oil paths extending from the hydraulic pressure regulating section (74) to the respective hydraulic pressure input sections (20D, 20D); so that the change-over valve (76) can supply the hydraulic pressure to either one of the hydraulic pressure input sections (20D, 20D). Or, trouble deciding sections (78R, 78L, 72) for deciding troubles in hydraulic circuit portions are provided, whereby the hydraulic pressures are controlled on the basis of the trouble decision, so that unfavorable supply of hydraulic pressure can be avoided.
