PROBLEM TO BE SOLVED: To provide a dog clutch for an automated transmission capable of shortening a speed change time.SOLUTION: In a dog clutch for an automated transmission, a high tooth 26a1 abuts with a clutch front tooth 23b1 first so that a sleeve 26 is decelerated or accelerated, and then the high tooth 26a1 and a low tooth 26b1 abut with the clutch rear tooth 23c1 so that the sleeve 26 is decelerated or accelerated, and as a result of this, the rotation of the sleeve 26 is synchronized with the rotation of a clutch ring 23 in a short time. The low tooth 26b1 as well as the high tooth 26a1 can engage with a clutch tooth groove 23d1 between the clutch tooth groove 23d1 and the clutch rear tooth 23c1, between the clutch front tooth 23b1 and the clutch rear tooth 23c1, and because of this, after the high tooth 26a1 and the low tooth 26b1 abut with the clutch rear tooth 23c1, the high tooth 26a1 and the low tooth 26b1 can plunge into a nearest clutch tooth groove 23d1 in a short time. Thus, speed change time can be reduced. |
