Abstract
A wet, multidisc friction engaging device, has alternately arranged, interleaved discs, each disc consisting of a core plate and a friction member on only one face of the core plate. The friction members are engageable with the core plates of adjacent discs. Some of the friction members have a high coefficient of static friction for high torque transmission. Other friction members have a high coefficient of dynamic friction to reduce shock and noise which tend to occur upon completion of engagement. The friction members having a high coefficient of static friction tend to have a relatively poor heat resistance. However, the core plates which they engage are thicker than the core plates engaged by the other friction members, so that heat generated upon engagement is diffused. The fact that thinner core plates are used for engagement by the friction members having a high coefficient of dynamic friction reduces the overall length of the device.
