  • Publication number: 20250054670
    Abstract: An electromagnetic-actuator (EA) assembly includes a first EA having a first coil-arrangement (CA) with a first coil-core (CC) and a first coil and having a first movable-magnetic-armature-body (MMAB) which is movable by a magnetic-field generated by the first CA from a first into a second position in which the first AB is attracted towards a first-surface, which is different from the first CC and arranged opposite the first AB, and contacts the first CC, and a second EA having a second CA with a second CC and a second coil and having a MMAB having a damping-device mounted on the second AB and which is movable by a magnetic-field generated by the second CA from a first into a second position in which the second AB is attracted towards a second-surface and abuts against the second-surface by the damping-device. The first and second surfaces are identical in construction.

  • Publication number: 20250035231
    Abstract: An electromagnetic-actuator (EA) including a coil-element (CE) having a coil-core (CC)/coil arranged about the CC-circumference. The CC has a symmetrical first-region (FR) having an axis-of-symmetry (AOS), the CC being surrounded by the coil, and a movable-magnetic-armature-body (MM AB) as a movable-actuator-element (MAE) interacts with the CE to produce an AB activation-movement, and is supported in the actuator by a bearing-device (BD) and movable from a first/second-position by activating the CE. The BD is radially-offset to the CC AOS, and the AB extends from the BD radially over the CC from a first/second-side of the CC, which has a second-region (SR) extending radially beyond the FR and is on second-side (SS) of the CC between the coil/AB in the direction of AOS such that an air-gap between CC/AB in direction of the AOS is smaller on the SS of the CC than on first-side when the AB is in first-position.

  • Publication number: 20250027577
    Abstract: A bearing device for fixing and bearing an armature body of an electromagnetic-switching or valve device in a pretensioned manner using a force, including a bearing-force-generating-element (BFGE) for generating a pretensioning-force for bearing the armature-body (AB) and a transmission-element (TE) formed separately from the BFGE and which is pressed in the direction of the AB by the generated pretensioning force when the bearing-device is installed to fix and bear the AB. The TE has a first-side and a second-side lying opposite the first-side, in which the first-side faces the BFGE, and the second-side faces the AB when the bearing-device is installed and contacts the ABy at at least one force-introduction-point (FIP) of the AB such that the force introduction point is mechanically decoupled from the BFGE. A guide device at least partly surrounds the transmission element, and guides and positions the TE on the FIP of the AB.

  • Publication number: 20250027576
    Abstract: An electromagnetic-actuator having a coil-assembly (CA) with a coil-core (CC) and a coil arranged about the CC circumference and a movable-magnetic-armature-body (MMAB) as a movable-actuator-element (MAE) which is movable by a magnetic-field generated by the CA, the AB being mounted by a bearing-assembly (BA) and movable from a first/second position. The BA has depressions in a first-bearing-section formed on the AB, the depressions being integrated into the AB and being formed in the shape of depressions mutually spaced in the direction of a bearing-axis (BA) of the AB and have an at least partly cylindrical bowl-like shape, and elevations in a second bearing-section formed on the actuator on the CA side, the elevations being formed in the shape elevations which are mutually spaced in the direction of the BA of the AB and have an at least partly cylindrical shape and each of which engages into one of the depressions.

  • Patent number: 11719356
    Abstract: A plate armature damping device for a tilting armature valve includes at least one damping body which can be fixed to a plate armature, with at least one damping material which, on an impact movement of the plate armature in the direction of a counter-element, is elastically deformable on impact on the counter-element.

  • Patent number: 6397152
    Abstract: A method and control apparatus for the correction of a mathematically determined torque in the drive train of a motor vehicle, in which a recognition signal for distinguishing between automatic and manual transmissions is produced and motor and transmission operating states (selected in accord with the recognition signal) in which the actual torque applied to the crankshaft is equal to zero are established. When the motor and transmission operating states are reached, the mathematically determined torque associated with the operating states is compared to the actual (zero) torque, and the difference between the mathematically determined torque and the actual torque is used as a control factor for the correction of additional computed torques.
