Title:
OIL SUPPLYING DEVICE FOR HYDRAULIC CONTINUOUSLY VARIABLE TRANSMISSION
Document Type and Number:
Japanese Patent JP3568135
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To facilitate a structure of an oil passage by providing a rotary pump on one or both outer peripheries of a cylinder block of a hydraulic pump, and constituting the rotary pump on a charge pump for supplying operating oil to a closed circuit.
SOLUTION: A rotary pump-type charge pump Cp is provided on the outer peripheral parts of cylinder blocks 10, 15. When an input shaft 3 is rotated, the cylinder block 10 of an hydraulic pump P is also rotated, a gear 29 is also rotated by the rotation of a gear 10a, operating oil in a housing 1 is sucked from a suction port and discharged from a discharging port to an oil supplying passage in a center section 2, the operating oil is supplied to a closed circuit formed between the hydraulic pump P and a hydraulic motor M, and a hydraulic actuator can be driven. As a result, the charge pump can be constituted by efficiently making use of outer peripheral spaces of the cylinder blocks, the axial length can be shortened, the driving structure can be simplified, and a compact structure can be made.
