Abstract
A transducer body includes a support comprising a pair of clevis halves; a sensor body coupled to each of the clevis halves, wherein the sensor body is disposed between the clevis halves and includes a generally rigid peripheral member disposed about a spaced-apart central hub, the central hub being joined to each of the clevis halves with the peripheral member spaced apart from each clevis half, wherein at least three flexure components couple the peripheral member to the central hub, and wherein the flexure components are spaced-apart from each other at generally equal angle intervals about the central hub; and a lockup assembly configured to selectively inhibit movement of the sensor body relative to the clevis halves.
Claims19
A transducer body, comprising:
- a support comprising a pair of clevis halves including a first clevis half and a second clevis half;
- and
- a sensor body coupled to each of the clevis halves, wherein the sensor body is disposed between the clevis halves and includes a generally rigid peripheral member disposed about a spaced-apart central hub, the central hub being joined to each of the clevis halves with the peripheral member spaced apart from each clevis half, wherein at least a flexure component couples the peripheral member to the central hub;
- a first plate member coupled to the first clevis half and a second plate member coupled to the second clevis half, wherein a portion of the sensor body is disposed between the first plate member and the second plate member.
A transducer body, comprising:
- a support comprising a first clevis half and a second clevis half;
- and
- a sensor body coupled to each of the clevis halves, wherein the sensor body is disposed between the clevis halves and includes a peripheral member disposed about a spaced-apart central hub, the central hub being joined to each of the clevis halves with the peripheral member spaced apart from each clevis half, wherein at least a flexure component couples the peripheral member to the central hub;
- and
- a lockup assembly comprising:
- a first plate member joined to the first clevis half and a second plate member joined to the second clevis half such that a first pair of opposed ends extend past first end surfaces of the first and second clevis halves and a second pair of opposed ends extend past second end surfaces of the first and second clevis halves, wherein inwardly facing surfaces of each pair of opposed ends face each other with an associated portion of the peripheral member disposed between the inwardly facing surfaces of each pair of opposed ends;
- a first actuator assembly operably coupled to the first pair of opposed ends to selectively hold the first pair of opposed ends to the associated portion of the peripheral member;
- and
- a second actuator assembly operably coupled to the second pair of opposed ends to selectively hold the second pair of opposed ends to the associated portion of the peripheral member.
