Definitions
- Magneto-rheological fluids are suspensions of magnetically polarizable particles, for example iron particles, which are finely distributed in a carrier liquid. When a magnetic field is applied, the particles become polarized, align themselves along the field lines of the magnetic field and form chains. There is a change in the viscosity of the magenta rheological fluid. This change can be made in a few milliseconds and is reversible. It is possible via the strength of the magnetic field to change the viscosity of the fluid to a solid state. About the height of the viscosity of the magneto-rheological fluid of the brake element, a rotational movement of the roller is controlled and controlled.
- a relative movement between the roller and the support member is braked, wherein the roller typically rotates about an axis of rotation relative to the support member.
- the rotational movement of the roller mounted on the axle can be influenced, preferably braked.
- This relative movement can be completely or partially braked, where "completely” means a standstill of the relative movement and “partially” a slowing of the relative movement.
- the brake element may be at least two parts, wherein a primary part is in operative connection with the roller and a secondary part is in operative connection with the support element.
- the primary part can be designed such that it is firmly mounted on the roller.
- the secondary part can be fixedly mounted on the support element. But it is also conceivable that the primary part of the
- the roller can be rotatably mounted on the axle.
- the roller can be rotatably mounted, for example, via a ball bearing on the axis.
- the axle can be connected in a rotationally fixed manner to the carrier element. But it is also possible to arrange the roller rotatably on the axis and rotatably support the axis in the support element.
- rotationally fixed is meant that the non-rotatable components are not rotatable with respect to a common axis of rotation relative to each other.
- Such a device is characterized by a lower cost of materials and space. The manufacturing costs are reduced.
- Such an elevator system has the advantage that it is quiet, wear phenomena are minimized. The maintenance and maintenance costs are low. In addition, the individual components can be better coordinated.
- the activation of the state of the magneto-rheological fluid via the elevator control has the advantage that the braking and damping properties can be adapted to the operation of the elevator and the rotational movement of the role of the roller guide on the state of the magneto-rheological fluid is adjustable.
- a carrier fluid of the magneto-rheological fluid mineral oil and / or a synthetic oil and / or ethylene glycol and / or water can be used.
- one or more adjuvants may be part of the magneto-rheological fluid. Such an adjuvant prevents sedimentation or agglomeration of the magnetically polarizable particles within the suspension.
- Adjuvants are exemplary stabilizers and / or viscosity improvers.
- FIG 1 Roller guide from the prior art
- Figure 5 a further embodiment of an inventive roller guide in the sectional view.
- Secondary part 8 is firmly connected to the support element 3.
- the brake element is not arranged as in Figure 2 between the roller 2 and the support member 3, but on an outer side 14 of the support member 3. This allows a compact design of the roller guide 1.
- the function and the effect further correspond to the embodiment of Figure 2.
