Abstract
A clutch having two stages for applying varied torque between an input shaft and an output shaft includes a clutchpack having input friction plates and output friction plates. The clutch further includes a first spring configured to apply a first pressure to the clutchpack to compress the clutchpack. The clutch further includes a second spring configured to apply a second pressure to the clutchpack to compress the clutchpack. The clutch further includes an engagement nut configured to move in response to rotation of the output shaft relative to the input shaft to compress the second spring in order to increase an amount of the second pressure applied to the clutchpack.

A clutch having two stages for applying varied torque between an input shaft and an output shaft, the clutch comprising:
- a clutchpack having input friction plates and output friction plates;
- a first spring configured to apply a first pressure to the clutchpack to compress the clutchpack;
- a second spring configured to apply a second pressure to the clutchpack to compress the clutchpack;
- and
- an engagement nut rotatably coupled to a first pressure plate of the clutchpack and configured to rotate with the first pressure plate in response to rotation of the output shaft relative to the input shaft to compress the second spring in order to increase an amount of the second pressure applied to the clutchpack,
- wherein the engagement nut defines a gap such that the first pressure plate is located within the gap to disengage the first pressure plate from the engagement nut in response to a predetermined quantity of rotations of the input shaft relative to the output shaft to limit the amount of the second pressure applied to the clutchpack by the second spring.
A clutch having two stages for applying varied torque between an input shaft and an output shaft, the clutch comprising:
- a clutchpack having input friction plates and output friction plates;
- a first spring configured to apply a first pressure to the clutchpack to compress the clutchpack;
- a second spring configured to apply a second pressure to the clutchpack to compress the clutchpack;
- a basket having an inner surface configured to engage the input friction plates;
- and
- an engagement nut rotatably coupled to a first pressure plate of the clutchpack and configured to rotate with the first pressure plate in response to rotation of the output shaft relative to the input shaft to compress the second spring in order to increase an amount of the second pressure applied to the clutchpack,
- wherein the engagement nut defines a gap such that the first pressure plate is located within the gap to disengage the first pressure plate from the engagement nut in response to a predetermined quantity of rotations of the input shaft relative to the output shaft to limit the amount of the second pressure applied to the clutchpack by the second spring.

- a first spring configured to apply a first pressure to the first pressure plate to compress the clutchpack;
- a second pressure plate;
- a second spring configured to apply a second pressure to the second pressure plate to compress the clutchpack;
- a basket having an inner surface configured to engage the input friction plates and an outer surface having basket threading;
- and
- an engagement nut rotatably coupled to the first pressure plate, configured to rotate with the first pressure plate, and having a nut outer surface having nut threading configured to engage with the basket threading such that rotation of the output shaft relative to the input shaft moves the engagement nut via engagement between the basket threading and the nut threading to compress the second spring in order to increase an amount of the second pressure applied to the second pressure plate, wherein the engagement nut defines a gap such that the first pressure plate is located within the gap to disengage the first pressure plate from the engagement nut in response to a predetermined quantity of rotations of the input shaft relative to the output shaft to limit the amount of the second pressure applied to the clutchpack by the second spring.
