Abstract
A magnetorheological brake device has a stationary holder and two brake components. A first brake component is connected to the holder for conjoint rotation and extends in the axial direction. A second brake component includes a hollow sleeve part which can rotate about the first brake component. A gap is formed between the first and second brake components. At least one, two or more rotatable transmission components are arranged in the gap. The gap is filled with a magnetorheological medium. The first brake component has a core which extends in the axial direction and is made of a magnetically conductive material, and an electrical coil which is wound about the core in the axial direction, such that a magnetic field generated by the electrical coil extends across the first brake component.
Claims18
A magnetorheological braking device, comprising:
- a fixed holder;
- at least two brake components, including a first brake component connected in a rotationally-fixed manner to said holder and extending in an axial direction, and a second brake component having a hollow sleeve part rotatably mounted about said first brake component;
- at least one rotatable transmission component disposed in a gap formed between said first and second brake components;
- a magnetorheological medium at least partially filling said gap;
- said first brake component having a core extending in the axial direction and formed of a magnetically conductive material, and an electrical coil wound axially around said core;
- said hollow sleeve part being formed of a magnetically conductive material and providing an outer ring for a magnetic field of said electrical coil;
- and
- wherein said magnetic field of said electrical coil extends transversely with respect to the axial direction through said core and enters through said at least one rotatable transmission component on opposite sides of the gap into said sleeve part, wherein the magnetic field closes itself in opposing halves of the sleeve part.
