Definitions
- the invention relates to a Verspannan Aunt for a drive train of a motor vehicle, with the aid of a plug connection between a transmission-side subunit, for example a double clutch, with a motor-side subunit, such as a dual mass flywheel, can be biased in the circumferential direction backlash to avoid noise during load changes.
- a transmission-side subunit for example a double clutch
- a motor-side subunit such as a dual mass flywheel
- a bracing arrangement is known from WO 2007/000151 A2, in which a dual mass flywheel is non-rotatably but axially displaceably connected to a double clutch via an interlocking toothing, wherein an output flange of the dual mass flywheel is connected via a tooth-shaped profiling to a corresponding counter profiling of an input flange of the double clutch ,
- the output flange of the dual mass flywheel is coupled via a bow spring with a Verspannblech having a protruding U-shaped mounting tab which can engage around a tooth of the tooth profiling of the output flange in the circumferential direction over its open end.
- the bracing arrangement has a flange, in particular an output flange of the torsional vibration damper or input flange of the clutch unit, wherein the flange has a profiling for transmitting a torque in the circumferential direction of a counter-profiling.
- a spring member fixed to the flange via a first end is provided for providing a biasing force in the circumferential direction from the flange to the mating profile and connected to a second end of the spring member
- the bracing plate is supported substantially at the radial height of the profiling of the flange in the circumferential direction via an only axially extending fastening tab on the opposite profile.
- the axial positioning of the bracing plate by means of a guided in a corresponding arc groove of the flange spacer bolt, via which the bracing plate is connected to the flange in the circumferential direction relatively rotatable but captive. occurrence Tende axial forces can thereby large area between the flange and the
- the fastening strap is designed as a substantially two-dimensional body with a sheet metal thickness corresponding to the clamping plate.
- the fastening tab is designed as a radially projecting tooth of a spline.
- Torsional rigidity in particular in the order of 10 to 60 Newton meters per degree of angle are.
- individual components forming the profiling and / or the counter profiling are formed from individual parts braced in opposite directions in the circumferential direction, such as, in particular, partial serrations (eg in WO 2012/031582 A1 : Profiling of the flange and fastening strap on the clamping plate). These components are held counter to the clamping force acting on them in a circumferentially rotated by an angular amount to each other by means of at least one holding element, so that a substantially force-free assembly of the axial connector forming profiling and counter-profiling is possible.
- the holding element When assembling or after joining the profiling and counter profiling, the holding element can be brought into a position in which the tension of the individual parts is released and an at least partial circumferential clamping of the plug connection is effected.
- the individual parts form one in width (in Starting direction) variable profiling or counter profiling, which are then braced without play in the space in which they engage respectively.
- the present invention has the object, at least partially overcome the known from the prior art disadvantages and in particular to show a bracing in which the holding element can be arranged in a particularly simple and space-saving manner. Furthermore, the retaining element should be arranged so that the tension of the assembled connector can be solved again and thus disassembly of the connector is facilitated.
- the invention relates to a bracing arrangement for a drive train of a motor vehicle, comprising an axial plug connection between a motor-side first subunit and a transmission-side second subunit, wherein the connector is clamped in a circumferential direction.
- the connector is formed by a profiling on the first subunit and a counter profiling on the second subunit, wherein at least one subunit at least one
- Clamping plate and a flange comprises, which together form the profiling or the counter profiling, wherein the flange member is an output flange of a torsional vibration damper or an input flange of a coupling device.
- the bracing plate and the flange Prior to the formation of the connector, the bracing plate and the flange are clamped in the circumferential direction in opposite directions to each other and can be fixed against the biasing force acting on them in a circumferentially rotated by an angular amount to each other first position by means of at least one holding element, so that one in width formed (in the circumferential direction) changed profiling or counter-profiling and a substantially force-free assembly of the axial connector forming profiling and Counter profiling along an axial direction is possible, wherein the retaining element, during or after assembly and by the formation of the connector, at least partially displaceable from a first position to a second position in which the tension of Verspannblech and flange solved and thus at least one partial,
- the holding element as a separate component (that is not materially connected or integrally connected to the flange) executed.
- This has the advantage that the retaining element can be made independently of the flange and the Verspannblech and thus in particular consists of a different material and has different thicknesses.
- the flange element (and in particular also the
- Clamping plate made of a hardened steel material, which allows only a slight degree of elastic deformation.
- the retaining element is but in particular made of a spring steel, ie z. B. a spring plate, which is elastically deformable to a considerable extent.
- the displacement of the retaining element in the second position takes place substantially in a radial direction.
- a movement in the axial direction (that is, along an axis of rotation of the bracing arrangement) is thus unnecessary.
- the space in the axial direction in such Clamping devices is very limited, a nearly exclusive Verfornnung in the radial direction is particularly advantageous.
- this feature (displacement in the radial direction) itself is also an invention and therefore can be tracked independently of the feature of mounting the retaining element as a separate component on the flange element.
- the displacement takes place in the second position by an elastic deformation of the holding element.
- the retaining element can spring back into the first position, when the Verspannblech and the flange are rotated to solve the tension of the connector in the circumferential direction in opposite directions to each other.
- the retaining element can thus cooperate again with a stop on the Verspannblech (when the holding element is attached to the flange) or on the flange (when the holding element is attached to the Verspannblech) and flange and Verspannblech against the force acting on them in a clamping force in the circumferential direction by an angular amount fix each other in a twisted first position.
- the connector can be released force-free again.
- the retaining element fastened to the bracing plate or flange element acts with a stop on the other component of the flange element and
- the holding element for releasing the connection of stop and holding element in the displacement in the second position, in the region of the stop in a radial direction movable.
- the bracing arrangement comprises a plurality of retaining elements, in particular exactly two, which are arranged along the diligentsnchtung at equal intervals on the flange or the Verspannblech.
- the holding element comprises an elastically deformable portion which extends into an intermediate space of the profiling or counter profiling of a subunit, this section being displaced by the counter profiling or profiling of the other subunit during assembly of the connector substantially in a radial direction.
- the holding element fastened to the flange element extends, starting from the flange element, in the axial direction and in the radial direction via the bracing plate arranged on the flange element, into an intermediate space of the profiling or counter profiling arranged on the flange element.
- the retaining element can be arranged and fastened on a side of the bracing arrangement facing the drive unit or the transmission on the flange element or the bracing sheet.
