摘要:
Spring comprising a first part (1) and a second part (2) moveable relative to each other, the first part being provided with at least one permanent magnet (4,4′), the second part being provided with at least one tooth (5,SM of a soft magnetic material which faces the at least one permanent magnet, whereby the total area of the facing surface varies as the first part moves relative to the second part, the first and/or the second part also being provided with at least one set of electrically conductive windings (7) which are connected to an electric power supply (8) in order to create a magnetic field for influencing the force-displacement characteristic of the spring. Also disclosed is an assembly of such a spring with a conventional spring and/or a damper, as well as a vehicle provided with such a spring.
摘要:
Spring having a first part (1) and a second part (2) moveable relative to each other along a longitudinal axis (L), a gap (3) being provided between the first part (1) and the second part (2), the first part (1) being provided with permanent magnets (4,4′), the second part (2) including soft magnetic material, the second part (2) having a variable permeability along the longitudinal axis (L) thereof for a magnetic field provided by the permanent magnets (4,4′) of the first part (1), wherein the second part (2), for providing the variable permeability for magnetic field, is provided with at least two teeth (5,5′) of soft magnetic material which each face a permanent magnet (4,4′) with a facing surface when the first part (1) is in an aligned position relative to the second part (2), the gap extending between the two teeth and the corresponding permanent magnets, wherein, when the first part is moving out of the aligned position relative to the second part along a longitudinal axis, the total area of the facing surfaces varies.
