A stop assembly for damper masses of a damper system has a stop device and a stop device carrier which holds the stop device. The stop device has at least one shoulder, which is intended to engage in at least one associated receiving portion of the stop device carrier. In at least one support region, the shoulder is oversized relative to the associated receiving portion to facilitate captive engagement in the receiving portion, and, at a distance from the at least one support region, the shoulder is undersized relative to the associated receiving portion to facilitate assembly-simplifying engagement in the receiving portion.

Stop assembly for damper masses of a damper system

A torsional vibration damper has a damper mass carrier at which is received at least one damper mass movable relative to the damper mass carrier and with at least one stop. The at least one damper mass has a stop side with a geometric shaping. At least one stop is associated with the damper mass, and has an axial overlap with the at least one damper mass in extension direction of a central axis and a stop profile at its side facing the stop side of the damper mass. At least one stop receiver is associated with the least one stop for the at least one damper mass. The geometric shaping which is provided at the at least one damper mass has a first contact region operative at least substantially in radial direction and a second contact region operative at least substantially in tangential direction. The first contact region can be brought into operative connection with the stop, and the second contact region can be brought into operative connection with the stop receiver.

Torsional vibration damper

A mass damper system includes a damper mass carrier having movable damper mass and a stop. The damper mass moves within a predetermined movement region during an operating state. A first movement region portion bounded by an initial position in which the damper mass is free from a deflection in circumferential direction and by a limit position in which the damper mass has undergone a deflection, and a second movement region portion defined by the limit position and a stop position in which the damper mass has come in contact with the stop. At a side facing the stop, the damper mass has a proximity profile that correspond to a stop profile such that in the first movement region portion the damper mass remains within a residual distance region relative to the stop in one extension portion of the proximity profile.

Absorber system

A torsional vibration damper is provided with a damper mass carrier at which is received at least one damper mass that is movable relative to the damper mass carrier and at least one stop. The at least one stop is associated with each stop side of the at least one damper mass. The at least one damper mass and the stop have an extension in extension direction of a central axis. The at least one damper mass has a plurality of damper mass elements in extension direction of the central axis, while the stop has in extension direction of the central axis a stop profile at its side facing the stop sides of the damper mass elements. The stop profile has different radial distances from the central axis in association with the damper mass elements.

A multiple disk clutch device for arrangement in a drivetrain of a motor vehicle between a drive unit and a transmission, includes at least an inner and an outer disk clutch arrangement that are radially staggered and associated with a transmission input shaft of the transmission. Each of the plural clutch disk arrangements includes a set of disks, the set of disks have an outer disk associated with an outer disk carrier and an inner disk associated with an inner disk carrier. The outer disks are operable to mutually engage the inner disks in a driving arrangement. Each of the plural disk sets includes at least one disk having a lining and at least one disk being unlined where one of the inner and outer disks of the inner and the outer disk clutch arrangements of the plural disk clutch arrangements is the lined disk.

Double or multiple disk coupling device and disk arrangement therefor

In a master/slave cylinder system for clutches or brakes, primary seals have bevels which interact with similar bevels of formations on housings of the respective cylinders. Along with the lowest possible friction in the region of the sealing lips, this permits carrying out uncomplicated pressure/negative-pressure filling in the case of the master cylinder. The primary seals slide by the wedge of effects in the direction of the pressure on the bevels of the annular formations and reduce the annular bearing face of the sealing lip in a frictionally optimized manner.

Primary seals for master-slave cylinder systems

In a cylinder for a hydraulic system, a seal has a sealing bead clamped between a housing of the cylinder and a supporting part which holds the sealing bead in a deformed state by pretensioning. The seal is reliably held in its intended position by the supporting part and, therefore, pressure fluctuations in the pressure space do not cause a relative movement of the seal and wear of the sealing bead.

Cylinder for a hydraulic system

An elastomeric seal seals a pipe which is held in a push-in part of a plug-in coupling relative to a cylindrical interior surface of a housing of the plug-in coupling, into which the push-in part is pushed together with the pipe. The seal is in prestressed contact with the interior surface of the housing via an outward-facing annular lip and with the pipe via a radially inward-facing annular lip. The elastomeric seal is connectable by positive fitting to the push-in part, this positive fit being lockable by the assembly of the pipe to form a non-releasable connection, the pipe having a cylindrical and uninterrupted exterior circumference in the region of the seal. The joint between the seal and the push-in part is simple to assemble and is lockable by the insertion of the pipe. The connection of the seal to the push-in part may be additionally secured, with certain changes of diameter, by compression of the web-shaped connection between them.

Seal for a plug-in connection

A hydraulic actuation device for the adjustment of units in motor vehicles includes a piston-cylinder unit with a housing and a piston displaceably arranged in the cylinder portion of the housing and/or in a guide sleeve in the housing. The piston-cylinder unit may be a slave cylinder or a master cylinder. The cylinder has a connection channel along one of its surface lines with an outer channel wall which is located in a portion of the connection channel located farthest from a center axis of the cylinder. The outer channel wall approximately follows a straight line and has an angle of inclination relative to the center axis which is greater than zero and preferably equal to or greater than a maximum installation angle of the installed position of the housing. The described arrangement of the deaeration bore hole at the highest possible location in the pressure space of the cylinder is advantageous for a deaeration of the hydraulic system for repairs and servicing.

Hydraulic actuation device

A sealing arrangement for providing a seal between a component and a cylinder in which the component is inserted includes a sealing ring supported in the axial direction in a circumferential slot on the component. The sealing ring has at least one static and one dynamic sealing lip. The sealing lips rest radially on corresponding sealing surfaces of the component and the cylinder. To reduce the noise generated during movement of the component in the cylinder, the geometrical shape of at least of one of the sealing lips is asymmetrical in the axial and/or radial direction with respect to a longitudinal axis of the component or a plane perpendicular to the longitudinal axis of the component, or cavities are distributed around a circumference of a base body portion of the sealing ring.

Sealing arrangement

A throttle device for the directionally-dependent influencing of the flow velocity of the fluid in hydraulic actuator systems, in particular of friction clutches in motor vehicles, with a throttle located between a master cylinder and a slave cylinder in the hydraulic system. The throttle is formed by a base body with at least one through hole, which through hole can be at least partly closed by a rubber-elastomer disc. The rubber-elastomeric disc is located on the side of the base body facing the slave cylinder, which disc radially overlaps a through hole, which through hole can be at least partly closed.

Throttle device for hydraulic actuator systems and for hydraulic

A detachable plug-type connector, in particular for the connection of a pressure line to a hydraulic cylinder with a pin-shaped inner part, which pin-shaped inner part can be inserted in a boring of an outer part. Between the outer part and the inner part there is a seal. The seal sits in the boring of the outer part, and in front of the seal there is a securing element which limits the axial travel of the seal in the extraction direction.
