Self-engaging clutch
An improved self-engaging clutch having a carrier plate with one or more clutch actuator fingers formed into the carrier plate.
1. A winch comprising:
a plurality of planetary gear sets each including corresponding sun, planet, and ring gears and a planet carrier; and
a clutch, the clutch including:
a cavity located on an exterior surface of a ring gear of one planetary gear set of the plurality;
another cavity located on a frame adjacent to the ring gear of the one planetary gear set;
a pin moveable into and out of said cavities;
at least one clutch actuator finger on a planet carrier of another planetary gear set of the plurality,
the at least one clutch actuator finger arranged to move the pin into and out of said cavities;
wherein the ring gear of the one planetary gear set is locked relative to the frame when the pin is located in the said cavities and free relative to the frame when the pin is located out of the said cavities.
2. The winch of claim 1 , wherein the at least one clutch actuator finger is integral to the planet carrier.
3. The winch of claim 1 , wherein the at least one clutch actuator finger is connected to the planer carrier.
4. The winch of claim 1 , further comprising:
a handle, the handle arranged to move the pin into and out of said cavities.
5. The winch of claim 1 , wherein the plurality of planetary gear sets includes a first, a second, and a third planetary gear set, the at least one clutch actuator located on the planet carrier of the second planetary gear set, the cavity located on the third planetary gear set.
6. The winch of claim 1 , further comprising:
a drum mounted on the frame and including a line wound about the drum.
7. The winch of claim 1 , further comprising:
a motor arranged to rotate the planetary gear sets.
8. A winch comprising:
a drum mounted on a frame and including a line wound about the drum;
a first, a second, and a third planetary gear set in communication with the drum, each said planetary gear sets including corresponding sun, planet, and ring gears and a planet carrier;
a motor arranged to rotate said planetary gear sets;
a clutch, the clutch including:
a cavity located on an exterior surface of the ring gear of the third planetary gear set;
another cavity located on the frame adjacent to the ring gear of the third planetary gear set;
a pin moveable into and out of said cavities;
at least one clutch actuator finger on a planet carrier of the second planetary gear set;
the at least one clutch actuator finger arranged to move the pin into and out of said cavities;
wherein the ring gear of the third planetary gear set is locked relative to the frame when the pin is located in the said cavities and free relative to the frame when the pin is located out of the said cavities.
9. The winch of claim 8 , wherein the at least one clutch actuator finger is integral to the planet carrier.
10. The winch of claim 8 , wherein the at least one clutch actuator finger is connected to the planer carrier.
11. The winch of claim 8 , further comprising:
a handle, the handle arranged to move the pin into and out of said cavities.
