Abstract
A friction material segment includes a first end and a second end, the first end including an edge having a first section having a reduced thickness and a second section having a second thickness greater than the reduced thickness section. A friction plate with a plurality of friction material segments and a wet-type friction clutch are also provided, as is a method for manufacturing the friction material segment.
Claims17
A friction plate comprising:
- a base and a plurality of friction material segments attached to the base to form a friction material ring, a first friction material segment of the plurality of friction material segments including an outer diameter, an inner diameter, a first end, a second end and a body between the two ends, the first end including an edge extending from the inner diameter to the outer diameter, the edge having a first section having a reduced thickness and a second section having a second thickness greater than the reduced thickness section, the body being the second thickness from the inner diameter to the outer diameter, the body, the first section and the second section are made of a first material and the body section and second section are less compressed than the first section to prevent oil seepage between the inner diameter and the outer diameter at the edge.
