VARIABLE SPEED PULLEY DEVICE
Document Type and Number:
Japanese Patent JP2017003028
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a variable speed pulley device capable of achieving miniaturization and weight saving of an auxiliary driving device.SOLUTION: A driving pulley 11 supported rotatably on a crank shaft 10, is provided with a pump chamber 21, and a suction port Pand a discharge port Pcommunicated to the pump chamber 21, the crank shaft 10 is provided with a rotor 22 for sucking an oil into the pump chamber 21 from the suction port Pby eccentric rotation in the pump chamber 21, and discharging the oil from the discharge port P, to form a hydraulic pump Pwith the driving pulley 11. The crank shaft 10 is provided with an oil supply passage 31 for feeding a make-up oil discharged from an oil supply pump 37 of a hydraulic supply source 35 to the suction port P, and an oil discharge passage 32 for guiding the discharged oil from the discharge port Pinto a tank 36 in the hydraulic supply source 35. An oil supply valve 38 is assembled to the oil supply passage 31, an oil discharge valve 39 is assembled to the oil discharge passage 32, and a speed of the driving pulley 11 is changed coaxially with the crank shaft 10 on the basis of an amount of the oil in the pump chamber 21.SELECTED DRAWING: Figure 1
