The invention discloses an actuator having a planetary roller screw. The actuator is particularly intended for operating vehicle clutch and has a planetary roller screw (PWG). According to the invention, a plurality of planetary rollers engages a screw and engages a gear ring which encircles the planetary rollers. The planetary rollers are located at two end parts thereof on a planetary roller rack and are supported in a sleeve which encircles the gear ring in an anti-rotation manner. According to the invention, the gear ring is at least upported by one gear ring bearing. The gear ring bearing absorbs axial force in the direction of an operation stroke and the opposite directiont of the operation stroke.

The invention relates to an attenuation circuit for an energy storage device having one or more energy storage modules which are connected in series in one or more energy supply lines and have at least one energy storage cell and a coupling device which has a multiplicity of coupling elements and is designed to selectively switch or bridge the energy storage cell in the respective energy supply line. The attenuation circuit comprises a current detection device which is designed to detect an output current of the energy supply lines or of the energy storage device and to generate an output current signal dependent on the output current, a control circuit which is coupled to the current detection device and is designed to control the output current signal to a desired current signal and to output a corresponding current control signal, and a pulse width modulation device which is coupled to the control circuit and is designed to control the coupling device of at least one of the energy storage modules in a clocked manner on the basis of the current control signal.

The invention relates to an intermediate plate (34) for a multi-disk clutch (20), in particular a two-disk clutch. The multi-disk clutch is used for coupling a drive shaft (12) of a motor-vehicle motor to at least one transmission input shaft (16, 18) of a motor-vehicle transmission, in particular for a dual clutch (10). The intermediate plate comprises: an annular body (48) for pressing, in a friction-closed manner, between a counterplate (22) that can be coupled to the drive shaft (12) and a pressure plate (26) that can be axially displaced in relation to the counterplate (22); and a contact tab (46), in particular formed integrally with the annular body (48), for displacably coupling the annular body (48) to the pressure plate (26), wherein the contact tab (46) has a contact body (42), which is formed by plastically deforming part of the contact tab (46) and which protrudes in the axial direction, for axially stopping against a restoring spring (38), which is connected to a pressure plate (26) or further intermediate plate following the intermediate plate (34) in the axial direction and which is designed in particular as a leaf spring. By means of the contact body (42) formed by plastically deforming the contact tab (46), transmission of an especially high torque by means of a friction clutch (20) in the case of different structural forms of a drive train of a motor vehicle is enabled by means of the additional friction surfaces provided by the annular body (48).

Disclosed is an exhaust gas aftertreatment device (10) for an internal combustion engine, especially for a ship diesel engine running on heavy oil, comprising a housing (11), an exhaust gas chamber (12) which is defined by the housing (11) and through which exhaust gas continuously flows, entering thereinto via an inlet (13) and exiting therefrom via an outlet (14), further comprising a noise damping chamber (15) which is defined by the housing (11), is coupled to the exhaust gas chamber (12), and holds a fluid or a pourable solid at a certain fill level that depends on the frequency of the exhaust gas noise to be damped.

The invention relates to a door handle assembly (3) for a motor vehicle (1), comprising a handle support (9), a handle (4) and a drive element (8). The handle (4) can assume at least an idle positionand a handling position. In case of installation in a vehicle door (2), the handle (4) extends flush with the outside (7) of the vehicle door (2) in the idle position and projects outward in a projection direction (14) relative to the outside (7) of the vehicle door (2) for actuation in the handling position. A base plate (10) is movably mounted on the handle support (9). Said base plate can be moved relative to the handle support (9), and the handle (4) is mounted on said base plate. The drive element (8) is kinematically coupled to the base plate (10). In normal operation, the drive elementis designed to move the base plate (10) from a base position, in which the handle (4) is arranged in the idle position thereof, into a readiness position, in which the handle (4) is arranged in the handling position thereof.
