摘要： A rotation moment transmission device (1) for a driving device of a furniture comprises a housing (2) comprising a first friction surface (3) having a circular cross-section, a rotation moment transmission member (4) having a rotation axis (DA) and a second friction surface (5), wherein the second friction surface (5) is movable radially with respect to the rotation axis (DA) and the first friction surface (3) and the second friction surface (5) are configured to collaborate for a rotation moment transmission, and a rotation moment introduction member (6) which is rotatable about the rotation axis (DA). One of the rotation moment transmission member (4) and the rotation moment introduction member (6) comprises an engagement member, the other one thereof comprises a contact surface (8, 8′, 8″, 8‴, 8⁗) and the engagement member (7) is configured to the contact the contact surface (8, 8′, 8″, 8‴, 8‴′) such that a twisting of the rotation moment introduction member (6) relatively to the rotation moment transmission element (4) moves the second friction surface (5) with respect to the rotation axis (DA) radially towards the first friction surface (3) or away therefrom.

摘要： A torque transfer apparatus and method of use is described. The apparatus comprises a plurality of elements assembled together to form a ring structure oriented in a plane around a longitudinal axis. The ring structure defines a first engagement surface. A structure defining a second engagement surface is rotatable with respect to the ring structure. The ring structure is operable to be moved between a collapsed condition and an expanded condition by movement of the plurality of elements, and movement between the collapsed condition and the expanded condition engages or disengages the first and second engagement surfaces. The apparatus can be configured to transfer a driving torque (e.g. a clutch) or a braking force (e.g. a torque brake).

摘要： A self-contained switchable wedge plate clutch, consisting of: a housing arranged to receive rotational torque; and a clutch assembly. The clutch assembly includes: an outer race non-rotatably connected to the housing; an output hub; a plurality of circumferentially aligned wedge plate segments, enclosed by the housing, radially disposed about the output hub; and an activation assembly at least a portion of which is enclosed by the housing. The activation assembly is arranged to displace the plurality of circumferentially aligned wedge plate segments to switch the self-contained switchable wedge plate clutch between: a locked mode for the sell-contained switchable wedge plate clutch, in which the housing and the output hub are non-rotatably connected; and an unlocked mode for the self-contained switchable wedge plate clutch, in which the housing and the output hub are rotatable with respect to each other.

摘要： A hydraulic transformer clutch employs radial hydraulic piston assemblies with integrated electrohydraulic actuation. The hydraulic transformer clutch includes: an output shaft, an output disc affixed to the output shaft for rotation therewith, an input shaft, a rotatable housing affixed to one of the input shaft or the output shaft for rotation therewith, a plurality of hydraulic cylinders, and a plurality of working pistons. The hydraulic cylinders are operatively connected to the rotatable housing, and are spaced about the rotatable housing. Each working piston is slidably mounted within a corresponding hydraulic cylinder of the plurality of hydraulic cylinders, and is positioned to be selectively pushed, when actuated, to create a rigid connection between the input shaft and the output shaft. One or more actuator pistons are pushed by an electromagnet and create pressure that is distributed on working piston surfaces and generates active torque.

摘要： A wedge plate clutch, including: inner and outer rings; circumferentially aligned wedge plate segments radially disposed between the inner and outer rings; a plurality of snap rings urging the circumferentially aligned wedge plate segments radially outwardly; and a cage. The plurality of snap rings includes: a first snap ring with a first circumferential gap; and a second snap ring with a second circumferential gap. The second circumferential gap is circumferentially off-set from the first circumferential gap. For a disconnect mode for the wedge plate clutch, the inner ring and the outer ring are rotatable with respect to each other. To transition from the disconnect mode to a connect mode for the wedge plate clutch, in which the inner and outer rings are non-rotatably connected, the cage is arranged to displace the circumferentially aligned wedge plate segments.

摘要： A wedge clutch imparts a wedging effect to selectively transfer power through powertrain components. The wedge clutch includes a plurality of wedge segments arranged annularly about an axis and configured to collectively constrict and expand with respect to the axis to correspondingly lock and unlock the clutch. Each wedge segment includes an aperture. A cage assembly is configured to control relative movement of the plurality of wedge segments with respect to each other. The cage assembly including a plurality of pins, each extending through one of the apertures to control the relative movement of the wedge segments.

摘要： A clutch includes a hub and a carrier concentric with the hub. One of the hub and the carrier defines a circular groove and the other of the hub and the carrier defines a tapered surface. A plurality of arcuate segments collectively define a ring that has a first edge disposed on the tapered surface and a second edge disposed in the groove. Each of the segments defines a first locating feature. An annular resilient member is seated on each of the segments and includes second locating features each connecting with one of the first locating features to secure the segments in a desired circumferential position relative to each other.

摘要： A clutch includes a carrier defining an annular groove and a hub coaxial with the carrier and defining an outer surface. The hub is axially movable relative to the carrier between at least a first position and a second position. A wedge disk has a first edge disposed on the outer surface, a second edge disposed in the annular groove, and a face extending between the edges and defining an annular shoulder. The disk engages between the carrier and the hub when the hub is in the first position to lock the clutch, and the carrier and the hub are rotatable relative to each other when the hub is in the second position. An annular retainer is configured to prevent radial expansion of the disk when the hub is in the second position and to permit radial expansion of the disk when the hub is in the first position.
