Abstract: An axial ondular washer made from a circularly annular, flat spring material having an ondular line with maxima and minima with respect to a centre plane, wherein these maxima and minima are defined as lying on different sides of the centre plane and in each case being tangent on a plane of a first or second abutment (1, 2), which plane extends parallel to the centre plane, is to be improved with regard to its initial compression behaviour.

Abstract: The invention relates to a clutch, particularly a multi-disk clutch, of an, in particular, manual transmission for, in particular, vehicles having a spring force of a spring device, said spring force influencing the adjusting force, which is produced in a power source and which serves to actuate the clutch. This clutch should be able to operated while maintaining predetermined closing and/opening times that are as precise as possible. In addition, the closing and/or opening times should be independent of possible changes in properties of the spring device. To this end, a clutch of the aforementioned type is characterized in that the spring device (3) and/or at least one of its thrust bearings is provided with a sensor (4), which detects solid body changes and which serves to determine the spring force exerted by the spring device (3), and a device for transmitting the determined measured values for controlling and/or regulating the adjusting power source.

Abstract: The invention relates to a flange coupling of two pipes, in particular the pipes of an exhaust system of a motor vehicle internal combustion engine. The coupling is characterized in that: each of the flanges is formed onto the corresponding pipe by the shaping of one of the pipe regions that form the respective flanges; a first of the two flanges is configured with a first connection pipe section, which engages radially in the interior of the second flange; a sealing ring is clamped between the flanges; the flanges are axially fixed by a clamping deice. The coupling is designed to be produced in an efficient manner, easy to mount and configured so that it functions reliably.

Abstract: A knock sensor for an internal combustion engine with an electronically evaluated vibration sensor should have a simple design and allow a rational installation. To this end, the vibration sensor is characterized in that the knock sensor comprises at least one spring washer (4, 4?) that is or can be tensioned relative to the internal combustion engine, and a piezoresistive amorphous carbon layer (5) is applied onto at least one face of the at least one spring washer (4; 4?).

Abstract: The invention relates to a motor vehicle door hinge comprised of a first hinge part (2), a second hinge part (3), a shaft section (4), which joins a hinge eye (10) of the first hinge part (2) and a hinge eye (17) of the second hinge part (17) to one another in an articulated manner, and of a door arrester unit (25), which produces a holding force that is to be surmounted by tensioning a spring unit (32). Preferred holding angles of the door arrester unit (25) are stipulated by detent markings. The aim of the invention is to create a motor vehicle door hinge that can be economically produced and mounted.

Abstract: The invention relates to a one-piece spring clip with a U-shaped profile, consisting in particular of spring steel, for flange connections, in a particular for flange connections of the exhaust gas pipes of motor vehicles. Said clip comprises first openings (3) that extend from a region of the spring-loaded back (1) to the ends of the two limbs with a U-shaped profile (2) for receiving the pipes that are connected by means of flanges. The aim of the invention is to provide a spring clip that is easy to produce, lightweight and has excellent spring-loaded characteristics. This is achieved by a flange connection that is provided with at least one second opening (4) with a closed circumference, in the form of a through-opening in the region of the spring-loaded back (1), said opening covering the vertex region of said back.

Abstract: A motor vehicle door hinge allows the door to be displaced relative to a doorpost in transverse and pivoting movements by means of a four-bar mechanism having a supporting arm and a control rod. The supporting arm is hingedly secured to the door's side and the doorpost by two respective hinge eyelets end areas. The control rod is coupled with a bearing plate on the door's side and the doorpost, whereby a corresponding hinge eyelet of the support arm is also coupled therewith, and with a hinge element on its end facing away from the side. The hinge acts upon the door's position by mounting the hinge element, coupled with the control rod, so that it can be displaced with and in the direction of said control rod relative to a corresponding hinge elements that is associated with a hinge eyelet of the supporting arm.

Abstract: A hinge for a motor vehicle door allows the door to be displaced with respect to a door pillar in a transverse movement combined with a pivoting movement by means of a four-joint mechanism that has a support arm and a control rod, both of which are hinged to the door and the door pillar. The support arm has a base support arm, at least one support arm element that can be detached from the base support arm and that has two hinge lugs supported on an extremity of the support arm, and means for interlinking the base support arm and the support arm element. The support arm element can be adjusted relative to the support arm through an axis that extends through the tangent plane of the base support arm and the support arm element by rotating them around a swiveling axis that is perpendicular to the tangent plane.

Abstract: A hinge part for attachment of a motor vehicle door and including a hinge part body formed of a thin-walled hollow extruded section having at least three chambers, and two pairs of hinge gudgeon provided on opposite sides of the hinge part body for mounting the hinge part on the motor vehicle body for rotation about two, spaced from each other, pivot axes.

Abstract: A door hinge for a motor vehicle door provided with a braking and retaining function, and including two hinge halves and a hinge pin extending through gudgeons of the two hinge halves for pivotally connecting the hinge halves together, with the hinge pin being secured in a gudgeon of one of the hinge halves against rotation and extending through a gudgeon of another of the hinge halves with a clearance, the hinge pin and bore of the gudgeon of another of the hinge halves having at least along a portion of their common axial extent, complementary, circumferential regions the circularity of which deviates from a regular circular cross-section of their complementary cylindrical surfaces.
