摘要： A fluid brake device has a case defining a fluid chamber. Magneto-rheological fluid is contained in the fluid chamber. A brake member is rotatably supported on the case and receives a braking torque according to the viscosity of the magneto-rheological fluid. The device has a movable member driven by a thermo-sensitive wax so that a volume of the fluid chamber is increased as the temperature in the fluid chamber is increased. The movable member is driven to maintain a pressure in the fluid chamber within an allowable range when the temperature in the fluid chamber is changed.

摘要： A fluid brake device has a rotor having a brake shaft penetrating a case to come into contact with magnetic viscosity fluid. A sealing sleeve is arranged to surround the brake shaft, and a seal gap is defined between the sealing sleeve and the brake shaft and communicates with a fluid chamber. The sealing sleeve has a flux guide that guides magnetic flux to the brake shaft through the seal gap. The brake shaft has a magnetic shaft extending in an axis direction, and a regulation layer that regulates the magnetic flux from passing by covering an outer circumference surface of the magnetic shaft. The brake shaft has an exposing part opposing to the magnetic flux guide, and the exposing part of the brake shaft is exposed from the regulation layer.

摘要： A fluid brake device has a brake shaft which penetrates a case. The case provides a fluid chamber for a magneto-rheological fluid. A magnetic seal has a magnetic seal sleeve which holds a small amount of the magneto-rheological fluid by magnetic flux. In addition to the magnetic seal, an axially pumping element is provided on an axial outside of the magnetic seal. The axially pumping element is provided by a shaft helical groove formed on an opposing wall of the brake shaft and/or a case helical groove formed on a surrounding wall. As the brake shaft rotates, the helical groove pushes the magneto-rheological fluid back to the magnetic seal. A combination of the magnetic seal and the axially pumping element may reduce leakage of the magneto-rheological fluid.
摘要翻译： 流体制动装置具有穿过壳体的制动轴。 该情况提供了用于磁流变流体的流体室。 磁性密封件具有通过磁通保持少量磁流变流体的磁性密封套筒。 除了磁性密封件之外，轴向泵送元件设置在磁性密封件的轴向外侧。 轴向泵送元件由形成在制动轴的相对壁上的轴螺旋槽和/或形成在周围壁上的壳体螺旋槽提供。 当制动轴旋转时，螺旋槽将磁流变流体推回磁性密封。 磁性密封和轴向泵送元件的组合可以减少磁流变流体的泄漏。
