Abstract
A device having an input element, an output element, and a drive element, the device having a first position configured such that the drive element is engaged with the input element and the output element to prevent movement of the input element in a first direction relative to the output element, the device having a second position configured such that the drive element is engaged with the input element and a further element to prevent movement of the input element in the first direction relative to the further element.
Claims (27)
1. A device having an input element, an output element, and a drive element, the device having a first position configured such that the drive element is engaged with the input element and the output element to prevent movement of the input element in a first direction relative to the output element, the device having a second position configured such that the drive element is engaged with the input element and a further element to prevent movement of the input element in the first direction relative to the further element.
2. A device as defined in claim 1 wherein the first position is configured such that the input element and the output element are moveable in the first direction.
3. A device as defined in claim 1 or 2 wherein the first position is configured such that the input element and/or output element and/or drive element is/are moveable in the first direction relative to the further element.
4. A device as defined in any preceding claim wherein the first position is configured such that the drive element is disengaged from the further element.
5. A device as defined in any preceding claim wherein the second position is configured such that the input element and the further element are prevented from moving in the first direction.
6. A device as defined in any one of claims 1 to 4 wherein the second position is configured such that the input element and the further element are moveable in the first direction.
7. A device as further defined in claim 6 wherein the second position is configured such that the input element and further elements are moveable in the first direction only to a limited extent.
8. A device as defined in any preceding claim wherein the second position is configured such that the drive element does not prevent movement of the input element in the first direction relative to the output element.
9. A device as defined in any preceding claim wherein the second position is configured such that the drive element is disengaged from the output element.
10. A device as defined in any preceding claim wherein the first direction is a first rotational direction.
11. A device as defined in claim 10 wherein the input element includes a first recess and a second recess, and the first position is configured such that the drive element is received in the first recess and the second position is configured such that the drive element is received in the second recess.
12. A device as defined in claim 11 wherein the first recess is spaced circumferentially from the second recess thereby defining a rotational axis of the input element and a longitudinal direction of the input element, the second recess having a first ramp that is orientated radially outwardly in the longitudinal direction, preferably the second recess has a portion contiguous with the first ramp and orientated parallel to the longitudinal direction.
13. A device as defined in claim 12 wherein the second recess has a second ramp that is orientated radially outwardly in a first circumferential direction.
14. A device as defined in claim 13 wherein the second recess has a third ramp that is orientated radially outwardly in a second circumferential direction opposite to the first circumferential direction.
15. A device as defined in claim 13 wherein the input element includes a third recess spaced circumferentially from the first recess and the second recess, the third recess having a first ramp that is orientated radially outwardly in the longitudinal direction and having a second ramp that is orientated radially outwardly in a second circumferential direction opposite to the first circumferential direction.
16. A device as defined in any one of claims 1 to 15 wherein the first position is configured such that a resilient device biases the output element in a longitudinal direction into engagement with the drive element and the resilient device biases the drive element in the longitudinal direction into engagement with the first recess of the input element, thereby defining a torque limiting clutch.
17. A device as defined in claim 16 including a further resilient element configured to bias the drive element in the longitudinal direction up the first ramp.
18. A device as defined in any preceding claim wherein the further component includes a projection having a radially inner surface at a first radius, the further component including a radial recess having an inner surface at a second radius larger than the first radius.
19. A device as defined in claim 18 wherein the second position is configured such that the drive element is at least partially received in the radial recess.
20. A device as defined in claim 19 when dependent on claim 5 wherein the further component is non-rotatable.
21. A device as defined in claim 19 when dependent on claim 6 including a mounting, wherein the further component is rotatable to a limited extent relative to the mounting.
22. A device as claimed in any preceding claim wherein the input element is provided with a primary torque input formation to allow torque to be applied to the input element, and a secondary torque input formation to allow torque to be applied to the input element in the event that the primary torque input formation is rendered inoperable.
23. A device as claimed in claim 22 wherein the primary torque input formation comprises a splined through aperture of the input element.
24. A device as claimed in claim 22 or claim 23 wherein the secondary torque formation comprises a plurality of alternating axial extensions and recesses which, in use, co-operate with a complementary plurality of alternating axial extensions and recesses of a drive element.
25. A device as claimed in claim 24 when dependent upon claim 23 wherein the extensions and recesses of the input element are arranged co-axially around the splined through aperture of the input element
26. A device having an input element, an output element, a first drive element and a second drive element, the device having a first position configured such that the first drive element is engaged with the input element and the output element to prevent movement of the input element in a first direction relative to the output element, the device having a second position configured such that the second drive element is engaged with the input element and a further element to prevent movement of the input element in the first direction relative to the further element .
27. A device as defined in any preceding claim including a gear rotary actuator operably coupled to the output element.
