Title:
潤滑回路
Document Type and Number:
Japanese Patent JP6779796
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a lubrication circuit capable of securing a lubricant flow rate and suppressing heating or abrasion, even in a case where a first lubrication part is at predetermined low-speed rotation of a fluid pump.SOLUTION: The lubrication circuit (hydraulic circuit 1) includes a first lubrication circuit 3 configured to supply lubricant to a friction clutch 2 as a first lubrication part, a second lubrication circuit 5 configured to supply temperature-controlled lubricant to a differential gear 4 as a second lubrication part, through an oil warmer 7, and a hydraulic pump 6. The lubrication circuit also includes a check valve 10 configured to open in low-speed rotation of the hydraulic pump 6 to allow supply of lubricant from the second lubrication circuit 5 to the friction clutch 2, and inhibit supply of the lubricant from the second lubrication circuit 5 to the friction clutch 2 in high-speed rotation of the hydraulic pump 6.SELECTED DRAWING: Figure 1
