ABSTRACT:
Wet-type friction members in an automatic transmission are provided with sets of grooves which diverge from each other, or with grooves which increase in width as they approach an edge of the frictional surface and which are rearwardly inclined in relation to the direction of rotation of the member which engages the grooved frictional surface. The grooves facilitate the removal of the oil film which is formed on the frictional surface, and thereby improves torque transmission and speeds engagement. In addition, the presence of the specially configured grooves causes the coefficient of friction to decrease gradually as relative rotational speed decreases, and avoids a sudden increase in the coefficient of friction as engagement is completed.
