Jaw clutch having profiled jaw clutch elements

摘要

A jaw clutch for the drive of motor vehicles has a first clutch half and a second clutch half which are axially displaceable relative to one another, both clutch halves are provided with axially protruding jaw elements which are distributed uniformly over the contact surface of the halves. In order to engage the clutch halves without synchronization and at the greatest possible difference in speed of rotation in an easy and rapid manner, the jaw elements are provided with transition zones from the front surface and side surfaces of the jaw element which are curved as seen in circumferential section wherein the radius of curvature is 6 to 13%, and the length of curvature in circumferential direction is 3 to 7% the average jaw radius.
