| 142 | Centrifugal clutch for power door locks | US349087 | 1994-12-02 | US5862903A | 1999-01-26 | James M. Gruden; Robert B. Brooks, Jr. |
| A centrifugal clutch for use with a power door lock actuator. The centrifugal clutch includes an independently rotatable pinion cup having an integral pinion gear which meshes with a jack screw, and a driver rotatably secured to an output shaft of a drive motor. The driver has at least one radially outwardly opening recess formed therein with at least one slider slidably retained within the recess. The slider is biased in a radially inward direction by magnetic lines of force which are provided by a permanent magnet mounted within the driver. Alternatively, a number of sliders can be formed of magnetic material such that the magnetic sliders are mutually attracted to one another in a radially inward direction. A centrifugal force is generated when the driver is rotated. The centrifugal force overcomes the magnetic attractive force to throw the sliders radially outwardly into positive driving engagement with the pinion cup. When the driver is no longer rotatably driven, the centrifugal force is eliminated and the magnetic attractive force then urges the sliders radially inwardly to break the positive driving engagement with the pinion cup. | ||||||

| A pneumatic starter (10) incorporates a pawl and ratchet clutch assembly (50) having a ratchet member (46) mounted to a drive member (40) powered by an air expansion turbine (20), and a plurality of ferromagnetic pawls (48) disposed circumferentially about the ratchet member (46) and operable in engagement therewith to transmit rotational drive torque from the drive member (40) to a driven member (60). Each of the pawls (48) is supported for pivotal movement into and out of engagement with the ratchet member (46). Springs (54) are provided for biasing the pawls (48) to pivot radially inwardly into engagement with the ratchet member (46). At least one magnet (82) is disposed in operative association with and radially outwardly of each pawl (48), whereby the ferromagnetic pawls (48) are held by the magnets (82) out of engagement with the ratchet member (46) when the driven shaft (60) is rotating at a speed above a desired reengagement speed. | ||||||
| 145 | Magnetic torque limiting clutch having overload disconnection means | US136014 | 1987-12-21 | US4825992A | 1989-05-02 | Alfred Skrobisch |
| This torque limiting clutch has a motor driven hub carrying two concentric cup-shaped rings with a cylindrical permanent magnet therebetween. Keeper plates are pivotally secured to the hub and overlay coplanar edges of the rings to which the keepers are magnetically attracted. The hub has an extension on which freely rotates a power output disk provided with projecting fingers that engage the keepers when they are in radial positions with respect to the hub. When an overload is applied to the output disk, the fingers turn the keepers until they are disengaged from the disk. The power output disk and hub are thus released to turn freely independently of each other, without generating frictional heat therebetween. | ||||||

| 916,434. Overload slip couplings. KOLLSMAN INSTRUMENTS CORPORATION. April 19, 1960 [April 20, 1959], No. 13710/60. Class 80 (2). [Also in Group XXXVIII] An overload slip coupling, for use in an aeroplane automatic pilot or the like, comprises an input shaft 46, Fig. 5, fast with which is a permanent magnet 72 and a friction washer 74 adjustably mounted upon screw-threads 76, the flanged end of a driven coupling-sleeve 80 rotatably and axially movable upon a spigot 78 fast with the shaft being drawn into engagement with the friction washer by the magnetic flux. A radial arm 82 fast with the driven sleeve 80 lies between two adjustable stop-screws 84, 86, so that rotation of the driven sleeve is limited, continued rotation of the input shaft 46 beyond a predetermined angle merely causing the coupling to slip. In the form shown, the coupling is applied to an altitude control device coupled to the automatic pilot of an aeroplane, pressure-sensitive bellows 58, 60, Fig. 1, connected by cranked arms 50, 52, Fig. 3, to a radial arm 48 fast with the shaft 46, moving with changes in ambient pressure caused by variations in the aeroplane height to rotate the shaft one way or the other. Fast with the driven sleeve 80 of the coupling is an arm 70 forming the I part of an E-I voltage-sensitive device 62 having coils 64, 66, 68 connected to the automatic pilot. Movement of the arm 70 causes changes in the voltage produced by the device 62, these voltage fluctuations being fed to the automatic pilot for adjustment of the aeroplane elevator surfaces. Alternatively, the device 62 may be replaced by a potentiometer system. | ||||||
