Title:
LUBRICANT SUPPLY STRUCTURE OF LOCK-UP CLUTCH CONTROL DEVICE FOR TORQUE CONVERTER
Document Type and Number:
Japanese Patent JP2015105717
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a lubricant supply structure of a LUC clutch control device for a torque converter capable of securing responsiveness in supplying a lubricant.SOLUTION: A LUC control device for a torque converter supplies an oil from a regulator valve 3 while adjusting its pressure by a control valve 4, supplies the oil to a LUC relay valve 6, and then supplies the same to a fastening oil chamber 5b or a releasing oil chamber 5a from the relay valve 6 to control a fastening state of the LUC. A lubricant supply structure 2 supplying a part of the oil to a lubricated portion, includes an oil supply passage 9 directly connecting the regulator valve 3 and the LUC relay valve 6, and a lubricant passage 11 connecting the LUC relay valve 6 and the lubricated portion 10. An amount of lubricant in an ON state of the LUC is reduced with respect to an amount of the lubricant in an OFF state of the LUC by switching the LUC relay valve 6 between ON and OFF positions.
