Abstract: Disclosed is a torque converter in a vehicle, in which a torsional damper reduces a natural frequency and absorbs vibration energy in an anti-resonance state for enhancing a vibration isolation function. The torque converter in a vehicle includes a torsional damper including a retaining plate coupled to the piston, a plurality of springs arranged at the retaining plate for imparting elastic force in a circumferential direction, a driven plate coupled to a spline hub which acts as a reaction force on the springs and forwards driving power to a transmission, and an inertial lever arranged between the piston and the driven plate, the inertial lever including a fixed pivot coupling portion coupled to the piston with a fixed pivot and a movable pivot coupling portion coupled to the driven plate with a movable pivot.

Abstract: The solenoid valve (10) has a poppet valve (41) which is operated to move between a position to close a port and a position to open the port. A fixed iron core (50) having a supporting leg (52) and a driving leg (51) is installed in a valve housing (11), and a movable iron core (60) which drives the poppet valve (41) is disposed between a valve driving member (42) and the fixed iron core (50). An arcuate sliding contact surface (61) is provided on one end portion of the movable iron core (60), and a sliding-abutting surface (62) which abuts on the sliding contact surface (61) is provided on a leading end portion of the supporting leg (52). When a coil (56) is de-energized, the sliding-contacting surface (61) is pressed onto the sliding-abutting surface (62) by a flat spring (70), with an abutting portion of the valve driving member (42) serving as a fulcrum of a tensile force applied to the movable iron core (60).

Abstract: A torsional vibration damper (1) with an adjustable resonance frequency. The damper has a support plate (2) arranged on a rotating shaft (3). A flexural spring arrangement (5) is mounted on the support plate (2) with a fixed inner end (6) and extends radially outwardly to an inertial mass (11). A support for the flexural spring arrangement (5) is provided constructed as at least one movable slide element (8) arranged in a radial guide (7). A restoring spring (16) exerts a restoring force on the movable slide element (8) in a direction opposite to the centrifugal force resulting from rotation of the shaft (3). The position of the slide element (8) on the flexural spring (5) is influenced by the centrifugal force and the restoring force. The magnitude of the restoring force is varied as a function of the rotational speed of the shaft such that the position of the slide element (8) moves to automatically adapt the resonance frequency of the torsional vibration damper (1) to the speed of rotation of the shaft (3).

Abstract: A four-bar linkage vibration absorbing device includes: crank members each coupled to a driven member of a damper device via a coupling shaft and each capable of swinging about the coupling shaft when the driven member is rotated; and a mass body that is coupled to the driven member via the crank members and that swings about the rotation center RC together with the crank members when the driven member is rotated. The driven member is coupled to a turbine runner of a hydraulic transmission device so as to rotate with the turbine runner.

Abstract: A vibration damping device 20 includes: a crank member 22 that is coupled to a driven member 15 via a first coupling shaft A1 and that is swingable about the first coupling shaft A1 along with rotation of the driven member 15; and an inertial mass body 24 that is coupled to the driven member 15 via the crank member 22 and a connecting rod 23 and that is swung about a center of rotation RC in conjunction with the crank member 22 along with rotation of the driven member 15. A component force of a centrifugal force that acts on the crank member 22 along with rotation of the driven member 15 in a direction that is orthogonal to the direction from the center of the first coupling shaft A1 toward the center of gravity G always acts on the crank member 22 as a restoring force that acts to return the inertial mass body 24 to the center of the swing range. The component force is maximum when the inertial mass body 24 is positioned at the center of the swing range.

Abstract: A centrifugal pendulum, in particular for arrangement on a drive shaft of an internal combustion engine, has a drive ring which can be mounted on a drive shaft for rotation therewith, and a synchronizing ring which is freely rotatable relative to the drive ring. The axis of rotation of the drive ring and the axis of rotation of the synchronizing ring are identical. The centrifugal pendulum further includes at least one pendulum body which is mounted movably on the drive ring. The pendulum body is kinematically coupled via at least one coupling element to the synchronizing ring such that, in the event of a rotation of the synchronizing ring relative to the drive ring in a first direction, the coupling element deflects the pendulum body toward the axis of rotation.
