Abstract: A multiple disc clutch includes an axially displaceable outer disc hooked into an outer disc carrier to provide a first friction surface, and an axially displaceable inner disc hooked into an inner disc carrier to provide a second friction surface for a friction pairing with the first friction surface. The outer disc has an outer coupling element for coupling to the outer disc carrier and the inner disc has an inner coupling element for coupling to the inner disc carrier. The outer disc has an outer ring, the outer coupling element extends radially from the outer ring, and the first friction surface is connected to the outer ring by an outer leaf spring element; or the inner disc has an inner ring, the inner coupling element extends radially from the inner ring, and the second friction surface is connected to the inner ring by an inner leaf spring element.

Abstract: A device for damping vibrations, especially a torsional vibration damper, comprising at least one primary part and a secondary part that are coaxial in relation to each other and limited rotatably relative to each other in a peripheral direction, whereby the primary part and secondary part (4) are coupled with each other by a vibration damper, and the secondary part can be at least indirectly coupled to a connecting element, especially a transmission input shaft. A ramp is provided that is at least indirectly connected to the secondary part, extends in a peripheral direction over a section, has an axially changing slope and acts on at least one counter element braced against a connecting element via a pretensioning unit.

Abstract: A dual clutch transmission has a driving plate defining concentric engagement surfaces, concentric friction plates, concentric pressure plates, and first and second clutch springs for operation of the pressure plates in clamping the friction plates against their respective engagement surface on the driving plate. The driving plate has a top hat type configuration, whereby the engagement surfaces are axially off set from one another. Cooling passages may be provided in the driving plate. The dct is preferably nested, wherein the outer pressure plate is in axial alignment with the radially inner portion of the driving plate, the inner pressure plate is in axial alignment with the radially outer portion of the driving plate, and the friction plates are arranged in axial alignment with one another.

Abstract: A clutch comprises at least one damper (22) having rotating input (24) and output (26) elements, elastic elements having a circumferential effect carried by the first (28) and second (30) guide washers connected in rotationally fixed manner to one of the input (24) and output (26) elements and via a web (36) connected in a rotationally fixed manner to the other input (24) and output (26) element. The clutch also comprises friction means (44), which are activated by annular displacements relative to the guide washers (28, 30) and to the web (36) and which have a friction element (46) capable of being coupled to the web (36) via the complementary circumferential stops that interact only when the web (36) angularly displaces in a predetermined direction with regard to the guide washers (28, 30).

Abstract: A clutch disk arrangement for a multiple-disk clutch includes at least two friction lining units, a hub element which is connectable to or is connected to the shaft so as to be fixed with respect to rotation and a support arrangement to which the friction lining units are connected substantially so as to be fixed with respect to rotation and by which the friction lining units are connected to or connectable to the hub element. The support arrangement includes a first support member which is connected to or connectable to the hub element and to which one of the friction lining units is fixedly connected, and at least one other support member to which at least one other respective friction lining unit is fixedly connected. The other support members are directly or indirectly connected to the first support member so as to be fixed with respect to rotation relative to it, but axially displaceable relative to the first support member.

Abstract: The rotary output element of a hydrokinetic torque converter can receive torque with limited play from the turbine or directly from the housing by way of a damper which operates in series with a lockup clutch. The lockup clutch can be engaged to transmit torque from the housing of the torque converter to the damper and the latter then transmits torque to the output element.

Abstract: A clutch plate having a hub and hub disc which are manufactured from two individual parts, wherein the two parts are non-rotationally connected by means of gear teeth so that there is essentially no play in the circumferential direction. Either the lining carrier or cover plate or both can thereby be guided with respect to a guide diameter of the hub by means of a plastic metal friction or sliding pair.

Abstract: A squib simulator and dispensing equipment tester has a threshold circuit d simulated load connected to a double-pole magnetically latching relay that switches contacts and turns on a test indicator lamp when the dispensing equipment delivers an input pulse of sufficient amplitude and duration. A power supply provides a logic level through a feedback circuit and the latching relay to the dispensing equipment indicating the status of the squib as either fired or faulted. A reset switch also uses the power supply to reset the latching relay for additional tests.
