グトルク以外は掛からない。 FIG. 2 shows a state in which the external teeth 35 of the sleeve 34B are engaged with the internal teeth 30 of the gear body 29B that is integrated with the input gear 24. From this state, if the sleeve 34A is moved in the direction of arrow A by an external force via the shifter 33, the sleeve 34A will be moved in the axial direction by the helical spline 32A provided on the inside, as shown in FIG. Rotates in the direction of arrow C (this rotation direction is the helical spline 3
(Can be reversed depending on the twist direction of 2A). When the serrations 31 of the sleeve 34A move axially to the position of the pawls 36 on the input gear 23, the indentations 31 engage the pawls 36. At this time, the external teeth 35 of the sleeve 34A and the internal teeth 30 of the gear body 29A
The claws 36 are arranged so that the phases are convex and concave to
The relationships between the notches 31, the number of external teeth 35 and internal teeth 30, the helix angle of the helical spline 32A, and the amount of axial movement are determined geometrically. When the sleeve 34A is further moved from the state in which the claws 36 and the notches 31 are engaged, either the input shaft 21 or the output shaft 22, whichever has the smaller inertia, rotates. Due to this rotation (turning operation), the sleeve 3
The notches 31 of 4A and the claws 36 are the outer teeth 35 and the inner teeth 3.
It moves in the axial direction while maintaining the phase relationship with 0, and the engagement between the external teeth 35 and the internal teeth 30 is completed. Before the engagement is completed, the pawl 36 and the notch 31 are disengaged, and since the torque of the drive machine is transmitted only by the external teeth 35 and the internal teeth 30, only turning torque is applied to the pawl 36.

Ｂの内歯３０とをかみ合わせる場合には、スリー
ブ３４Ｂを矢印Ｂ方向へ移動させる。この時の作
動は前述の場合と同様である。 Conversely, the external teeth 35 of the sleeve 34B and the gear body 29
When engaging the internal teeth 30 of B, the sleeve 34B is moved in the direction of arrow B. The operation at this time is similar to that described above.

According to the invention described above, it is possible to easily change gears by moving the sleeve using a shifter without providing a turning device, and the device can be made smaller and lighter. Also, compared to hydraulic clutches, torque is transmitted mechanically using gears, so large-capacity joints can be manufactured.
Moreover, the reliability of the communication ability is high.
