摘要:
A drive for the compressor (14) of a vehicle air conditioner having a magnetic clutch (20) for mechanically driving the compressor shaft (16) within a predetermined range of torque; a rotatable input element (22) on the magnetic clutch (20) to be rotated by the vehicle motor at varying speeds with changes in the vehicle motor's speed; a first electromagnetic element (42) on the rotatable input element (22); a compressor shaft (16) on the output side of the magnetic clutch for supplying torque to drive the compressor; a second electromagnetic element (46) on the compressor shaft (16) with a magnetic field between the first and second electromagnetic elements to rotate the compressor (14); and an electric control (32) for varying the electrical power to the electromagnetic clutch (20) as the vehicle motor changes speed to vary the magnetic field and torque being applied to rotate the compressor shaft (16).
摘要:
A rotational control apparatus (10) includes a first rotatable assembly (20) and a second rotatable assembly (96). The first assembly (20) is rotatably mounted to a first support mount (12). The second assembly (96) is rotatably mounted to the first assembly (20) and is axially moveable relative to the first assembly (20). The first and second assemblies (20, 96) have respective coaxial surfaces (28, 106A) adjacent to and spaced from one another and further have respective axial surfaces (46, 102) that frictionally engage one another when the second assembly (96) is in a first axial position and disengage when the second assembly (96) is in a second axial position. The second assembly (96) is capable of rotation independent of the first assembly (20) when the second assembly (90) is in the second axial position. The rotational control apparatus (10) includes an eddy current drive (132) comprised of a first eddy current coupling assembly (134) associated with the coaxial surface (28) of the first assembly (20) and a second eddy current coupling assembly (136) associated with the coaxial surface (1 06A) of the second assembly (96), the second eddy current coupling assembly (136) adjacent the first eddy current coupling assembly (134) with an air gap (114) therebetween.
