Definitions
- the invention relates to a double clutch with vibration isolation device in the wet room, which is particularly suitable for small available space, for example in a motor vehicle.
- wet double clutches have been equipped with external damper systems due to their complexity.
- the use of a double clutch increases the installation space compared to a simple clutch, the use of an external damper system further increases the overall installation space.
- the present invention has the object, at least partially overcome the known from the prior art disadvantages.
- the object is solved by the features of the independent claims.
- Advantageous developments are the subject of the dependent claims.
- the invention relates to a double clutch with vibration isolation device in the wet room, which has at least the following components:
- a first friction pack for releasably connecting the input shaft to the first output shaft and a second friction pack for releasably connecting the input shaft to the second output shaft;
- a plurality of vibration isolation devices comprising at least one damper and at least one centrifugal pendulum, which can be arranged in the wet room, wherein a first vibration isolation device on the first Reibvers and a second vibration isolation device on the second Reibvers is arranged.
- a dual clutch is usually arranged to produce a frictional connection between a drive unit and a double gear. In this double gear two waves are provided, which are arranged alternately for successive translations. By means of the double clutch can thus be connected in a change from a translation to the other translation already upon release of the first transmission shaft, the second transmission shaft. This shortens the switching time and achieves an almost unbreakable torque transmission.
- the output shaft of a drive unit thus usually represents the input shaft, because in most operating conditions, the torque originates from the output shaft.
- the first and second transmission shaft then represent the first and second output shaft.
- the dual clutch has a first friction pack and a second friction pack, which are set up for releasably connecting the input shaft to the first output shaft or to the second output shaft.
- the first and the second friction pack are arranged in a wet space.
- a vibration isolation device is arranged on the first friction packet and a further vibration isolation device is arranged on the second friction packet.
- the vibration isolation devices are configured to (largely) prevent the passage of vibrations, for example from a drive unit such as an internal combustion engine or an electric motor to, for example, a drive train.
- a drive unit such as an internal combustion engine or an electric motor
- an external damper unit has been used.
- This wet space is preferably the enclosed cooling space of a double clutch, in which the frictional engagement between, for example, a drive unit and a drive train takes place, and in which the resulting frictional heat is dissipated.
- This wet room is completely filled with a liquid, usually an oil.
- the liquid has additional damping effects which act on the damper system.
- a damper system has a mass that can be elastically suspended to counteract the vibrations.
- a lower mass than in an arrangement outside the wet space can be used, so that the total mass and in particular the total rotating mass can be reduced, and thus the efficiency is increased.
- vibrations in certain states such as when starting the machine in a defined frequency range unavoidable.
- a damper and at least one centrifugal pendulum in the wet room is provided. This additional damping effects occur through the liquid in the wet room, so that such a damper system can be made smaller than dry arrangements. This significantly reduces the rotating mass.
- a friction package to which a respective vibration device can be arranged, is composed of at least one pressure plate and at least one corresponding friction plate.
- the pressure plate rotates synchronously with the input shaft and is rotationally fixed for this purpose.
- the pressure plate is usually axially displaced and pressed against the corresponding friction disc.
- the friction disc usually does not run with it in the released state, so that the damper system does not rotate and does not damp in an arrangement between the friction disc and the respective output shaft. Thus, no unnecessary co-rotating mass is installed.
- the respective damper system can be adapted to the vibration characteristic of the respective friction pack.
- At least one centrifugal pendulum is arranged on one of the output shafts.
- a centrifugal pendulum By arranging a centrifugal pendulum on one of the output shafts, the effect of a centrifugal pendulum can be exploited outstandingly; because a centrifugal pendulum has a resonance range in which the centrifugal pendulum counteracts an incoming oscillation. For all other frequencies, the centrifugal pendulum has no influence.
- a centrifugal pendulum which is arranged on one of the output shafts, be adapted to the respective existing frequencies on the output shaft, which may differ from the other output shaft.
- At least one damper is furthermore arranged on the output shaft, which is arranged between the at least one centrifugal pendulum and the output shaft.
- At least one centrifugal pendulum is arranged at the outermost radius within the wet space.
- the wet room is a closed area in which the rotating components of the friction pack are arranged.
- This wet space is designed to reduce the co-rotating mass, namely the cooling liquid, as small as possible.
- this is arranged as far outside as possible within the wet room.
- the size of the centrifugal force depends on the radius of the suspension of the centrifugal pendulum.
- the centrifugal force is a factor of the natural frequency, which defines the resonance range.
- the resonance range is adjustable over the radius of the suspension.
- the outermost radius is thus a radius at which the respective centrifugal pendulum can be arranged taking into account the movement of the centrifugal pendulum and the reliability of the coupling. In particular, this means that between the outermost radial outer edge of the centrifugal pendulum and the inner wall of the boundary of the wet space no further component is provided.
- a motor vehicle which comprises a drive unit with an output shaft, a drive train and a dual clutch as described above.
- a dual clutch By using a dual clutch according to the above description components can be used in the motor vehicle, which must not be designed for vibrations that can occur on the output shaft. Furthermore, the proposed double clutch can be used in small vehicles, which provide only a small space available.
- the drive unit in the motor vehicle is arranged in front of a driver's cab and transversely to a longitudinal axis of the motor vehicle.
- Most motor vehicles today have a front-wheel drive and therefore preferably arrange the drive unit, for example an internal combustion engine or an electric motor, in front of the driver's cab and transversely to the main drive direction.
- the space is particularly low especially with such an arrangement and it is therefore particularly advantageous to use a small size coupling.
