Abstract: A leaf spring arrangement, especially for connecting a pressure plate to a housing, comprises a plurality of adjacent leaf spring elements, where each leaf spring element has a first attachment area for establishing the connection the pressure plate, a second attachment area for establishing the connection to the housing, and a connecting area extending between the first attachment area and the second attachment area. At least certain areas of at least two of the leaf spring elements are spaced apart between their first attachment area and their second attachment area.

Abstract: A pressure plate assembly for a friction clutch includes a housing arrangement and a pressure plate arrangement, which is held by at least one leaf spring arrangement with freedom of axial movement relative to the housing arrangement. The at least one leaf spring arrangement is fixed by a first attachment area to a first fastening area of the pressure plate arrangement and by a second attachment area to a second fastening area of the housing arrangement. The end area of the first fastening area and/or the second fastening area curves away from the minimum of one leaf spring arrangement, this end area being located in the area along which the at least one leaf spring arrangement extends.

Abstract: A pressure plate is held by at least one leaf spring arrangement so as to be movable axially with respect to the housing. The at least one leaf spring arrangement cooperates in a first coupling area thereof with the pressure plate for transmission of force and cooperates in a second coupling area thereof with the housing for transmission of force. For this purpose, the at least one leaf spring arrangement cooperates in one of first coupling area and second coupling area with the component group of housing and pressure plate cooperating with this coupling area for transmission of force in order to transmit force in only one circumferential direction.

Abstract: A housing arrangement is coupled to a pressure plate arrangement by at least a first coupling arrangement so as to be relatively movable in direction of an axis of rotation (A). The first coupling arrangement comprises at least one coupling element which is secured at least in a first coupling area to a coupling portion of the pressure plate arrangement and is secured in a second coupling area to a coupling portion of the housing arrangement. The at least one coupling element of the at least first coupling arrangement comprises fiber material.

Abstract: A thrust plate assembly comprises a housing arrangement and a pressure plate arrangement which is coupled by at least one coupling arrangement to the housing arrangement so as to be movable in direction of an axis of rotation (A). It further comprises an axial path limiting arrangement for limiting the axial movement of the pressure plate arrangement with respect to the housing arrangement in an axial movement direction, this axial path limiting arrangement having, at the housing arrangement, at least one stop area which is contacted by a counter-stop area of the pressure plate arrangement associated with this stop area when the pressure plate arrangement assumes a predetermined relative position with respect to the housing arrangement.

Abstract: A pressure plate is held in a housing so as to be movable in direction of an axis of rotation (A) and is acted upon or can be acted upon by an energy accumulator. The pressure plate is coupled with the housing by at least one coupling arrangement which acts upon the pressure plate axially during torque transmission. The thrust plate assembly further comprises a lifting force generating arrangement for generating a lifting force for the pressure plate.

Abstract: A thrust plate assembly comprises a housing having a rotational axis, a pressure plate arrangement which is movable axially in the housing arrangement, and at least one coupling arrangement by which the pressure plate is coupled with the housing for transmission of torque, wherein a force component acting axially upon the pressure plate can be generated by the at least one coupling arrangement when the pressure plate is acted upon by rotational force in a first direction with respect to the housing arrangement. The at least one coupling arrangement is connected in a first coupling area thereof with a first coupling portion of the pressure plate and is connected in a second coupling area thereof with a second coupling portion of the housing, wherein the first coupling area and the second coupling area of the at least one coupling arrangement are axially offset relative to one another.

Abstract: The present invention generally relates to the attachment of a centrifugal mass or a modular clutch to the output end of a crankshaft of an internal combustion engine. For this purpose, axially-oriented gear teeth can be introduced in both parts, e.g. a serration, and there can be a central screw element which can extend into a threaded portion in the crankshaft. The present invention teaches that an axially-oriented spring bias can be applied to both parts to create a reliable connection between the parts of the gear teeth.

Abstract: This invention relates to a friction clutch with a membrane spring in a pulled or pushed clutch design, in which there is a second membrane spring/plate spring which provides assistance to the release force and which, when the friction clutch is engaged, generates little or no release force, and generates an increasing release force as the release travel increases.
