Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
