Description

Technical area

The invention relates to a propeller shaft coupling, comprising a support body which receives receiving bushes which are arranged to be movable relative to each other, wherein each receiving bush is associated with at least one elastically deformable layer, which bears against the support body,

State of the art

Such propeller shaft couplings are for example from the DE 10 2006 012 758 A1 or the DE 10 2008 007 761 A1 known.

For torque transmission between two shafts elastic shaft couplings are often used to dampen occurring torsional vibrations and shocks. The known elastic shaft couplings are usually made of the connecting flanges of the interconnected shafts or shaft ends and arranged between the connecting flanges propeller shaft coupling.

The propeller shaft coupling has at its outer periphery at defined angular intervals receiving bushes, which can accommodate means for connecting the propeller shaft coupling with the connecting flanges.

Cardan shafts of rear or all-wheel drive vehicles must always compensate for an axial or angular offset. At the same time, high torques of up to 4000 Nm must be transmitted.

Modern, high-loading internal combustion engines with a low number of cylinders generate considerable vibrations and vibrations. There is therefore a need for a propeller shaft coupling, with which vibrations and vibrations can be damped or eradicated.

Presentation of the invention

The invention is therefore based on the object to realize an arrangement which ensures cost-effective production operable connection of two shaft ends.

The present invention achieves the aforementioned object by the features of patent claim 1.

Thereafter, the above-mentioned propeller shaft coupling is characterized by a vulcanized Gelenkwellentilger comprising an elastomer and a flywheel, wherein the flywheel is vulcanized as inertial mass by the elastomer to the support body.

According to the invention it has been recognized that this can eliminate a Tilgernabe. It has been concretely recognized that a Tilgernabe can be substituted by already existing components of a propeller shaft coupling. This can save costs. In addition, this is no element of the Gelenkwellentilgers in Schraubverbund nor is a press fit with tight and costly tolerances required. The flywheel is vulcanized as inertial mass by an elastomer to the support body. In that regard, an arrangement can be realized, which ensures a cost-effective production operable connection of two shaft ends and integrates a Gelenkwellentilger.

Consequently, the object mentioned above is achieved.

The Gelenkwellentilger could be connected to the support body and have a flywheel. By a relative to the support body rotatably movable flywheel effectively vibrations can be redeemed in drive shafts.

The support body could consist of a Anbenteil and a counterpart, which accommodate three, six or eight receiving bushes between them, wherein the flywheel is connected to the attachment piece of the support body. It is advantageous that the flywheel ring can be connected and calibrated before mounting the propeller shaft coupling with the Anbindungück. Specifically, the flywheel can be calibrated radially inward. The connection of the flywheel to the Anbenteil, in particular by vulcanization, can be done without damaging other components of the propeller shaft coupling.

The attachment piece could have at least one attachment flange, but preferably three attachment flanges, which engage over the counterpart in the axial direction. By forming a tether flange of the flywheel can be easily vulcanized to the Anbenteil. Against this background, the flywheel ring is vulcanised. As a result, an elastic rotational movement of the flywheel ring relative to the support body can be reliably realized. The flywheel is in this case connected by an elastomer to the support body.

The flywheel ring could be mounted on at least three rolling body, which are accommodated between the support body and the flywheel ring and having mushroom-shaped enlarged ends, whereby after a radial calibration of the flywheel inwardly an axial fixation ensteht. Preferably, the rolling bodies are received in a recess of the elastomer, which binds the flywheel to the support body.

The flywheel could be applied to a torsion stop. As a result, the rotational movement of the flywheel is limited and defined brakes.

The flywheel could be assigned a captive. As a result, an axial release of the flywheel from the support body is prevented.

The captive could arise during assembly of the support body and have radially projecting webs which are connected to the counterpart. When mounting the support body, namely the axial assembly of the counterpart and the Anbindestücks, creates the captive and unfolds by the radially projecting webs their effect.

The support body could be connected to a multi-armed flange, which is arranged coaxially to the support body. At the preferably three-armed flange, a shaft end can be connected.

In the multi-armed flange, a centering sleeve could be accommodated, which is arranged coaxially to the multi-armed flange. As a result, a shaft journal can be received and defined centered. In the centering sleeve, an elastic layer is preferably added, which can engage around the shaft journal.

The propeller shaft coupling described here is preferably used in motor vehicles, since high torques and vibrations occur in internal combustion engines.

There are now various possibilities for embodying and further developing the teaching of the present invention in an advantageous manner. For this purpose, on the one hand to the subordinate claims, on the other hand, to refer to the following explanation of preferred embodiments of the propeller shaft coupling according to the invention with reference to the drawing.
