Title:
SEGMENT TYPE FRICTION PART
Document Type and Number:
WIPO Patent Application WO/2011/033861
Kind Code:
A1
Abstract:
A segment type friction part is configured in such a way that there are formed supply paths which supply lubricating oil to the surfaces of segment pieces, and that furthermore, oil groove openings on the outer circumference sides of the segment pieces are formed in such a way as to expand curvilinearly and linearly. Due to the above, lubricating oil is sufficiently supplied to the surfaces of the segment pieces from the outer circumference sides thereof or from the inner circumference sides thereof, and the gap between the segment type friction part and a separator plate is secured. Furthermore, spaces where lubricating oil flows to the outer circumferences of the segment pieces are sufficiently secured, resulting in reduced drag torque.
