Definitions

• Torsional vibration damper for a rotatable shaft, in particular a transmission or an internal combustion engine
• the present invention relates to a torsional vibration damper for a rotatable shaft, in particular a transmission or an internal combustion engine according to the preamble of claim 1.
• the present invention has for its object to further develop a torsional vibration damper of the generic type in a simple and cost-effective manner to the effect that this torsional vibration damper another, necessary for a vehicle function to reduce in this way the cost of manufacturing a vehicle.
• the torsional vibration damper is expanded into a brake, in particular by the fact that the basic part, in particular the damper housing or connected to parts such as
• a damper housing of the torsional vibration damper may also be formed as a ring-like base, on which another Dämpglangsglied, for example, an elastomeric ring is arranged. If one speaks below of a damper housing, it is insofar the particularly preferred embodiment.
• a torsional vibration damper can also assume a braking function for a corresponding vehicle. It is not necessary, a completely independent brake manufacture and assemble, as an essential part of a brake consists of the damper housing by the construction according to the invention.
• the invention thus also provides a combination of a torsional vibration damper with a brake, in particular a drum brake, which is preferably usable as a parking brake of the vehicle.
• the construction according to the invention can be used as a so-called parking brake.
• the brake can be designed as a drum brake or as a disc brake.
• the training as a drum brake is z. B. for the case of the application as a parking brake particularly advantageous because the drum brake by the concentration of the mass on the outer diameter has a high moment of inertia and in addition builds relatively small by the possibility of Kraft self-amplification. Also, the effect of the torsional vibration damper is improved by the now given possibility of simultaneous braking. The damping behavior can now be displayed adaptively within certain limits. The torsional vibration damper is therefore no longer a simple mechanical system with a fixed characteristic, but can be adjusted by means of, for example, electronic control of the brake within limits of the current requirements.
• the control is preferably carried out in an electronic control unit, which in an already existing unit z. B. may be integrated in the transmission control.
• Figures 1 to 6 are each half-sections formed by braking torsional vibration damper in different embodiments
• the reference numeral 1 designates a rotary-vibration damper for a transmission of a motor-driven vehicle, the torsional vibration damper in a preferred embodiment in each case comprising a damper housing 2 with a receiving chamber 3 for an attenuator, for example in FIG Shape of a flywheel 4, which is held in a bearing 5 and surrounded in its shearing gap (at 3) of viscous liquid.
• the receiving chamber 3 is closed by a cover 6.
• radially adjustable brake shoes 7 are pressed against the damper housing 2 or against rings 9 with a brake pad 8, which are fixed in a stationary manner on the vehicle side-that is, not circumferentially fastened Damper housing 2 are preferably made in one piece.
• a ring 9 integrally formed on the damper housing 2 is held by an annular flange 10 projecting radially beyond the damper housing 2, wherein the annular flange 10 in turn integrally connects to the damper housing 2.
• brake shoes 7 are pressed with brake pads 8.
• the brake shoes 7 could be pressed onto the outside of the ring 9.
• the brake shoes 7 are pressed with the brake pads 8 directly on the outer annular surface of the damper housing 2.
• the rings 9 or the damper housing 2 form the brake drum of a drum brake.
• the said flange 1 1 is formed radially projecting directly against the damper housing 2.
• the aforementioned flange 1 1 is integrally formed on a damper housing 2 integrally formed, axially projecting support ring 12, wherein the support ring 12 has a smaller diameter than the outer diameter of the damper housing 2. held by the support ring 12 flange 1 1 extends again radially in the outer direction of the damper housing 2 and has an outer diameter
• the flange 11 used as a brake disk protrudes beyond the outer annular surface of the damper housing 2. stands, while the flange 1 1 in the embodiment of Figure 6 approximately in
• the actuation of the brake shoes 7 is preferably carried out by an electric motor.
• electrical setpoint generator are required, with an electronic control unit for this purpose preferably in an already existing unit z.
• the transmission control of a vehicle can be integrated. It is theoretically conceivable also a hydraulic or pneumatic actuation.
• the brake can thus also be used to adjust the damping behavior of the torsional vibration damper.
• Brake shoes are pressed, manufactured in one piece with the damper housing 2. Deviating from this, it is of course also conceivable to connect corresponding rings or flanges as separate components fixed to the damper housing 2.
