초록 ▼

A controllable brake (20) including a rotor (28) supported by a shaft (30) which is rotatably supported by bushings (42) received in housing (22). A coil assembly (48) creates a magnetic field within a pole piece (32), which is preferably manufactured from a powdered metal material, which preferably has a density of between about 6.8 and 7.0 gm/cm. A magnetically-soft medium is contained within first and second gaps (86, 88) located between pole piece (32) and rotor (28). In one aspect, a magnetic saturation zone (25) reduces the propensity of magnetizing the shaft (30). In another, the pole halves (24, 26) are received in radially-spaced pole pockets (37) formed in the housing (22) and include an axial bias spring (70) to ensure intimate contact. In another aspect, a lip projection (76) traps fluid (23) between the lip projection (76) and shaft (30) and minimizes fluid exposure to the shaft seal (44). In another aspect, cooling fins (55) or a projection (53) restrains rotation of the housing (22). In another aspect, a spring (46) centers the rotor (28) relative to the housing (22).

[ What is claimed is:] [1.] A controllable brake, comprising(a) a shaft,(b) a rotor manufactured from a highly magnetically permeable material having first and second rotor surfaces, a working portion, and an outer periphery, said rotor being interconnected to said shaft to restrain relative rotation therebetween,(c) a housing including a magnetically-soft yoke which is manufactured from a highly magnetically permeable powdered metal material, said magnetically-soft yoke having a recess formed therein, said recess receiving said working portion of said rotor and forming a first gap adjacent to said first rotor surface and a second gap adjacent to said second rotor surface, said housing including a portion shaped relatively thin compared to a part of the housing including the yoke, said portion formed adjacent the shaft for preventing magnetic field buildup at a shaft sealing area,(d) a magnetically-soft medium contained within and at least partially filling said first and second gaps, and(e) means for generating a changeable magnetic field adjacent to said magnetically-soft yoke, said changeable magnetic field being directed to cause said magnetically-soft medium within said first and second gaps to change rheology thereby causing a change in torsional resistance of said controllable brake when said means for generating a changeable magnetic field is energized.
