Disk 1 and sleeve 3 rotate about common fixed axis A-A. Engaging collar 5 slides on sleeve 3 along axis A-A. Jaws 2 are rigidly attached to disk 1 and jaws 4 to sleeve 3. Sleeve 3 serves as a guide for collar 5 with jaws 6 which slide in the spaces between jaws 4. To engage the clutch it is necessary to substantially reduce the speeds of the shafts and to shift collar 5 to the left.
