摘要:
Es wird eine Vorrichtung (1) zum Betätigen eines Schaltelementes (2) einer Getriebeeinrichtung mit in einem Kolbenraum (3) zwischen einer ersten und einer zweiten Endstellung verschiebbar angeordneten Kolbenelement (4) beschrieben. Das Kolbenelement (4) ist in Abhängigkeit eines in dem Kolbenraum (3) vorliegenden hydraulischen Drucks und einer an dem Kolbenelement (4) angreifenden Rückstellkraft einer Rückstelleinrichtung (5), die der zu dem hydraulischen Druck im Kolbenraum (3) äquivalenten Betätigungskraft entgegenwirkt, hydraulisch betätigbar ausgeführt. Die Übertragungsfähigkeit des Schaltelementes (2) ist durch eine in Richtung der ersten Endstellung des Kolbenelementes (4) wirkende und an dem Kolbenelement (4) angreifende Gesamtkraftkomponente reduzierbar und mittels einer in Richtung der zweiten Endstellung des Kolbenelementes (4) wirkende und an diesem angreifenden Gesamtkraftkomponente erhöhbar. Erfindungsgemäß ist das Kolbenelement (4) mittels einer mechanischen Halteeinrichtung (8) entgegen einer in Richtung der ersten Endstellung des Kolbenelements (4) wirkende und an diesem angreifende Gesamtkraftkomponente wenigstens in einer vordefinierten Stellung, die von der ersten Endstellung verschieden ist, haltbar.

The invention relates to a clutch unit for using in the drive train of a motor vehicle, between a drive unit and a transmission comprising at least one transmission input shaft. The clutch unit comprises at least one wet clutch device (K1, K2) provided with a plurality of clutch elements, especially disks, which are at least partially wetted by a coolant, for example oil, said coolant being cooled by a cooler (3').

The invention relates to a device for axially positioning a clutch device (99), especially a dual-clutch device (99), on a rotary drive (62), wherein the clutch device (99) is mounted so as to rotate about a rotational axis (ax) of said rotary drive. A retaining nut (80) is coaxially screwed with the rotary drive (62), and the clutch device (99) is indirectly or directly supported on said nut in an axial direction.

Lubricating oil supply holes are drilled into a first member that is fitted to a plurality of first annular plates by a spline. Of splines to which each lubricating oil supply hole corresponds, lubricating oil grooves provided in the plurality of first annular plates do not overlap the splines on at least one of the front and rear surfaces of the first annular plates, and therefore lubricating oil flowing out of the lubricating oil supply holes is dispersed in a circumferential direction and flows from the inner periphery to the outer periphery of the first annular plates, rather than gathering in each lubricating oil groove and flowing in an outer peripheral direction. As a result, a force generated by an axial lubricating oil flow, which acts in a direction for causing the second annular plates to contact friction materials on the first annular plates, is suppressed, leading to a reduction in drag torque.

The invention relates to a clutch system, comprising at least one clutch device, especially for arrangement in a drive train, between a drive unit and a transmission. Said clutch device (202) can be actuated through the conveying of a pressure medium and/or is able to operate under the influence of an operating medium. One aspect of the invention provides that a secondary medium that acts as the pressure medium for actuating or as the operating medium for operating the clutch arrangement is supplied by a pump arrangement (208) which supplies a primary medium and a secondary medium supply device (220) which is connected to the pump arrangement or a secondary pump arrangement (220). Said secondary medium supply arrangement or secondary pump arrangement has the following: at least one pressure absorption element which is movably arranged in a housing, which during operation, is exposed to the primary medium that is supplied by the first-mentioned pump arrangement, on at least one pressure absorption surface, and which can be caused to move by conveying the operating medium; and at least one interactional element which is movably arranged in the/a housing, which is motionally coupled to the pressure absorption element, which during operation, interacts with the secondary medium on at least one interactional surface, and whose action enables the supply of the secondary medium, optionally by displacement and/or introducing an acceleration and/or introducing a swirl.
摘要:
A rotary transmission coupling (56) having a rotary input (86) and at least one rotary output (91) connected through clutch (93) located within a casing (90, 101), the clutch (93) being operable by a hydraulic actuator (104) responsive to hydraulic pressure generated by a pump (95) worked by the rotational speed differential between said input (86) and said output (91). The coupling includes a hydraulic valve (120) also responsive to the hydraulic pressure to permit actuation of the clutch (93) above a predetermined hydraulic pressure. The valve is located in a wall (90) of the casing.
摘要:
A part of a rubber layer of the base section of a piston seal is replaced with a reinforcement ring with high rigidity, and a part of the reinforcement ring reaches the root of a seal lip. This provides the piston seal with required rigidity. Further, providing an outer diameter side radial section on a piston body secures a contact width coming into contact with a section to be pressed. A piston has a piston body (111) having a clutch pressing section (111f) provided so as to be in surface-contact with a multiple disc clutch (105), a reinforcement ring (112) fitted on the outer periphery of an outer cylinder section (111e) of the piston body, and an outer peripheral seal lip (113a) provided on the reinforcement ring and in sealing contact with the inner peripheral surface (102a) of the outer peripheral section of a housing (102).
摘要:
Die Erfindung betrifft ein hydraulisches Kupplungsbetätigungssystem mit einer hydraulischen Kupplungsbetätigungseinrichtung, die mindestens einen Kupplungsgeberzylinder aufweist, der über eine Druckmediumsleitung mit einem Kupplungsnehmerzylinder in Verbindung steht, der dazu dient, eine Kupplungseinrichtung zu betätigen, wobei der Druck in der Druckmediumsleitung über mindestens eine Notöffnungsventileinrichtung entspannbar ist, um in einem Notfall ein Öffnen der Kupplungseinrichtung zu ermöglichen. Das hydraulische Kupplungsbetätigungssystem zeichnet sich dadurch aus, dass die Notöffnungsventileinrichtung eine Dichtungsträgereinrichtung für ein Dichtungselement umfasst, die beziehungsweise das mit Hilfe eines Elektromagneten aus einer Öffnungsstellung, in der eine Druckmediumseintrittsöffnung geöffnet ist, in eine Schließstellung bewegbar ist, in der das Dichtungselement die Druckmediumseintrittsöffnung verschließt.
