A liquid metal rotary connector (16) for a vehicle steering mechanism (10) utilizes a conductive alloy comprising Gallium, Indium, Tin and Zinc to electrically couple stationary and rotary terminals (26a, 26b; 28a, 28b) of the connector (16). The alloy is a liquid at ambient temperatures, and has a melting point of -36°C, though testing has shown that it operates satisfactorily at temperatures as low as -40°C. In a preferred arrangement, the rotary connector (16) provides a two-wire connection through which power is supplied from the steering column (12) to the steering wheel (14), and electronic modules (22, 24) located in the steering column (12) and the steering wheel (14) support bi-directional data communication through voltage and current modulation of the supplied power. |

An eddy current drive (711) has an electromagnet (15, 17) and an armature (19). Either one of the electromagnet or the armature is coupled to a motor shaft (31) so as to rotate therewith, while the other is coupled to a load portion (21). The motor can rotate at a continuous speed, while the speed of the load portion can vary by varying the energization of the electromagnet, so as to vary the coupling between the electromagnet and the armature. The electromagnet is energized by way of bearings (613, 615). The bearings provide a rotary coupling. In another embodiment, an electrical generator (713) is provided. The rotation of the motor shaft (31) generates electrical current that is used to energize the electromagnet. The amount of the electrical current that is provided to the electromagnet can be varied to vary the output speed of the load portion. | ||||||

To minimize the effects of magnetohydrodynamic surge forces acting on the liquid metal (32) in the collector gap (31) of an acyclic generator (10), fluid flow impedance members in the form of annular, axially spaced compliant brushes (44) are disposed in the outboard liquid metal containment gap (40b) defined between closely spaced, stator and rotor stepped surface formations (36, 38). These brushes (44) impede the communication to the liquid metal (32) in this containment gap (40b) of pressure fluctuations generated in the liquid metal (32) in the collector gap (31) resulting from variations in the generator current transiting the collector gap (31). A hydrostatic pressure head may thus be maintained consistently at a location intermediate the collector and containment gaps (31, 40b) for pumping the liquid metal (32) in a recirculating path. |

The claimed pick-up device contains considerable less mercury than could be expected, being small dimensioned and cheap. The device (1) is mounted between a bearing arrangement (40) which e.g. lubrication contineously need to be measured, and a measuring apparatus (45). The end-part (15) of shaft (14) which is coupled to a bearing arrangement (40) comprises a hollow space (20) provided with a very small quantity of mercury (25). A contact-pin (23) being a part of cover (10) is provided with a bore (36) for a connecting plug to apparatus (45). When the shaft (14) rotates the mercury (25) by centrifugal forces will form a layer in space (20) such that the electrical current (46) can run from the bearing arrangement (40) via said shaft (14), its end-parts (19, 25, 23, 36) to the measuring apparatus (45). |
