Embodiment
(embodiment 1)
Fig. 1 to Fig. 3 shows a kind of embodiment of the present invention, and wherein Fig. 1 is structural representation of the invention；Figure
2 be the junction cut-away structure chart of the pusher dog, reversing cover and the guide pad that commutates of the present invention；Fig. 3 is of the invention eight kinds different shapes
State schematic table.
See Fig. 1 to Fig. 3, a kind of double rolling key clutch with pusher dog, including interior star-wheel 1 and fixed with the interior star-wheel and joined
The commutation guide pad 2 connect, is provided with outer ring 3, the interior star-wheel of freewheel clutch and outer ring can be made in the outside of the interior star-wheel 1
For driving link, wedging and the transcendent function of freewheel clutch are realized；Between the lateral surface of the outer ring 3 and the interior star-wheel 1
Roller 4 is uniformly provided with, pusher dog 5 is provided between the commutation guide pad 2 and the interior star-wheel 1, on the side of the pusher dog 5
Ratchet 6 is fixed with, the ratchet is on the side mutually close with the interior star-wheel, is provided with the outside of the commutation guide pad
Reversing cover 7, commutation latch 8 is fixed with the reversing cover, skewed slot 9 is provided with the pusher dog, the pusher dog is arranged on institute
