The evaluation device is provided to perform and / or supplement the determination of the torque operating state by analyzing signal components of the measurement signal with a cut-off frequency greater than the current rotational frequency of the shaft.

The object of the present invention is to provide an apparatus and a method for condition monitoring of an elastomer coupling or a dual-mass flywheel or a torsion damper.

According to the invention this object is achieved by the method according to claim 1 and the device according to claim 7. Expedient developments can be found in the dependent claims.

According to a method according to the invention for condition monitoring of an elastomer coupling or a dual mass flywheel or a torsion damper, a characteristic curve for a plurality of operating points of the elastomer coupling or the dual mass flywheel or the torsion damper is generated, wherein at least a first and second rotational speed and at least one temperature and at least a first and a second Torque of the elastomeric clutch or the dual mass flywheel or the torsional damper detected by an apparatus for condition monitoring of the elastomeric clutch or the dual mass flywheel or the torsional and evaluated based on a comparison with characteristic curves resulting from the generated characteristic to determine a status of the elastomer clutch or the dual mass flywheel or the torsional damper ,

In other words, based on a comparison with characteristics resulting from the generated characteristic, the status of the elastomeric clutch or the twin-mass flywheel or the torsional damper can be determined. Alternatively, the second torque can also be calculated from the rotational accelerations and the rotational mass inertia of the secondary side.

The condition monitoring may be for an elastomeric clutch or a dual mass flywheel or a torsion damper, in other words for a torque-damping and / or a rotation-damping connector.

Under the condition monitoring of the elastomer coupling or the dual-mass flywheel or the torsion damper, an automated monitoring in the sense of a condition monitoring, also referred to as "condition monitoring" in English to understand. This can be a change in state and / or malfunction of at least the elastomeric clutch or the dual mass flywheel or the torsional damper but also a malfunction in a drive train in which the elastomeric clutch or the twin-mass flywheel or the torsion damper is arranged can be determined. Furthermore, the remaining service life of the elastomer clutch or the dual mass flywheel or the torsion damper can be determined.

Both the elastomer coupling and the dual mass flywheel and the torsion damper are at least partially elastic, in particular designed for vibration reduction. The elastomer coupling and the dual-mass flywheel and the torsion damper are provided to connect two shafts rotationally fixed but vibration damping and / or vibration-reducing each other. The elastomeric clutch, the dual mass flywheel, and the torsional damper are configured, for example, to reduce engine noise and / or engine powertrain in the powertrain.

The detection, calculation and evaluation of the two speeds and / or torque at two different locations allows a state detection of the elastomer coupling or the Dual mass flywheel or torsion damper. Depending on the temperature and speed of the elastomeric clutch or the dual mass flywheel or torsional damper or a frequency of a working machine, the status and / or the state change of the elastomeric clutch or the dual mass flywheel may be detected based on comparison with previously detected characteristics.

A normal operation of the elastomeric clutch or the twin-mass flywheel or the torsional damper may be defined as a state given by an operating parameter or a characteristic which is within a range or which, for example, is above or below a threshold value. The limit value depends on the intended use as well as on the respective elastomer coupling or the respective dual-mass flywheel or the respective torsional damper and is automatically determined on the basis of a reference measurement or initial measurement in the new state for each operating state.

In the context of the method according to the invention, on the one hand, the elastomer coupling or the twin-mass flywheel or the torsion damper is monitored and the operation is documented and, on the other hand, error messages can be output in the event of malfunction, in particular exceeding and / or falling short of the limit value.

In other words, the calculation of a dynamic characteristic curve is automated, wherein the new state of the elastomeric clutch to be monitored or the dual mass flywheel or the torsional damper is performed by a first measurement for all operating conditions as a function of speed, temperature or frequency. These characteristics are used as a reference for condition monitoring. This advantageously makes it possible for the parameters calculated automatically from this characteristic curve to be determined in the sense of status monitoring of the statuses and to be displayed.

As an output or as information to the operator, for example, an automated alerting to a significant change of state up to an automated recommendation will give. Alternatively, a subsequent manual analysis option is available.

The present invention advantageously makes it possible to automatically calculate and store a dynamic characteristic curve. Furthermore, from this characteristic parameters must be determined automatically, by which both the status of an elastomer coupling, a dual-mass flywheel or a torsional damper is to be determined, as well as an assessment of an elastomer coupling, a dual-mass flywheel and a damper in the sense of condition monitoring is possible.

For example, speed measurements on the primary and secondary side as well as torque measurements on the primary and secondary side are carried out as a basis for calculation. Alternatively, it is also possible to calculate the secondary-side torque by means of the rotational acceleration to be calculated from the measurement of the secondary-side rotational speed-an angular acceleration-and the secondary moment of inertia to be entered.

The optional additional benefit of an automated monitoring of the combustion process and the possibilities for the safe operation of large combustion engines - such as cylinder misfires - or the combustion process optimization by the information provided are made possible by the present invention.

In particular, the primary side on the drive side adjacent to a first end face of the elastomeric clutch or the dual mass flywheel or the torsion damper is formed, the secondary side is the output side formed on a second end face of the elastomeric clutch or the dual mass flywheel or the torsional damper.

The degree of isolation of the elastomer coupling or of the dual-mass flywheel or of the torsion damper changes over the course of time during operation of the elastomer coupling or of the dual-mass flywheel or of the torsion damper, in particular due to signs of aging. Since the degree of isolation is decisive for the assessment of the state of the elastomer coupling or of the dual-mass flywheel or the torsion damper, the remaining service life of the elastomer coupling or the twin-mass flywheel or the torsion damper can be determined.

According to a preferred embodiment, a temperature sensor is provided for detecting the temperature at the elastomer coupling or at the dual-mass flywheel. Alternatively, it is also conceivable that the device for condition monitoring of the elastomer coupling or the dual mass flywheel or the torsion damper comprises no temperature sensor and the temperature is transmitted to the elastomer coupling or the dual mass flywheel or the torsion damper from another measuring device to the device for condition monitoring.

In particular, for the universal applicability of the method and the condition monitoring device, it is possible to input characteristic values and / or designations of the drive train and / or the elastomer coupling or the dual mass flywheel or the torsion damper as well as other components of the drive train in a user interface of the state monitoring device.

The present invention advantageously makes it possible to make an assessment of elastomer couplings, dual mass flywheels and / or torsion dampers in the sense of condition monitoring on the basis of the parameters to be calculated from a characteristic curve.

Since the prerequisite for this is the measurement and storage of characteristics for a predetermined number of operating points - depending on the speed, frequency, torque and temperature - and the measurement effort for manually determining and entering the required characteristics for all relevant operating conditions, sizes and the consideration of Environmental influences can not be afforded economically, it is advantageous to ensure an automated determination of the characteristics during operation. In other words, the automated determination of the characteristic curves can automatically determine characteristic curves for the predetermined number of measured operating points and store them for the following comparative assessment.

Further measures improving the invention will be described in more detail below together with the description of a preferred embodiment of the invention with reference to the single figure. The single FIGURE shows a simplified schematic representation of a drive arrangement according to the invention with a device for condition monitoring of an elastomer clutch or a dual-mass flywheel or a torsional damper.

According to the single FIGURE, a drive arrangement according to the invention has a drive machine designed here as an internal combustion engine 8th on that over a first wave 9a with an elastomer coupling 1a or with a dual-mass flywheel 1b or a torsion damper 1c connected is. Furthermore, the elastomer coupling 1a or the dual mass flywheel 1b or the torsion damper 1c on the output side via a second shaft 9b with a gear 11 connected. The following is simplicity only on the elastomer coupling 1a referenced, wherein the dual mass flywheel 1b or the torsion damper 1c is no longer mentioned, although the explanations also for the dual mass flywheel 1b or the torsion damper 1c are valid. The drive assembly further includes a condition monitoring device 10 the elastomer coupling 1a ,

The device for condition monitoring 10 the elastomer coupling 1 , Includes a measuring and evaluation device 5 and a first and second sensor element 6a . 6b for detecting a first and second speed. Furthermore, the device comprises condition monitoring 10 the elastomer coupling 1a also a temperature sensor 7 the at the elastomer coupling 1a is arranged and for detecting the temperature at the elastomer coupling 1a is provided. The two sensor elements 6a . 6b are designed as speed sensors and as well as the temperature sensor 7 with the measuring and evaluation device 5 connected, wherein the two sensor elements 6a . 6b axially spaced at the elastomeric coupling 1a are arranged to a status of the elastomeric coupling 1a determine.

For this purpose, the first and second rotational speed or rotational nonuniformity as well as the temperature and the first and the second torque at the elastomer coupling 1a from the condition monitoring device 10 , Especially in the measuring and evaluation device 5 recorded and evaluated. In the present case, the first speed of the elastomer coupling 1a on the primary side 3 the elastomer coupling 1a and the second speed of the elastomeric clutch 1a on a secondary side 4 the elastomer coupling 1a detected.

Thus, speeds or rotational irregularities of the elastomer coupling 1a from the two sensor elements 6a . 6b on the primary and secondary side 3 . 4 the elastomer coupling 1a measured. Based on these signals forms the measuring and evaluation device 5 Parameters for assessing the condition of the elastomer coupling 1a and / or the prime mover 8th and / or the entire drive train.

By means of the two speeds and depending on the temperature at the elastomer coupling 1a becomes a degree of isolation of the elastomer coupling 1a certainly. The degree of insulation of the elastomer coupling 1a changes with age of the elastomer coupling 1a , Deviations below a minimum limit of isolation or above a maximum limit of isolation may result in loss of efficiency of the elastomer coupling 1a to lead.

Furthermore, by means of the two speeds and as a function of the temperature of the elastomer coupling 1a a respective phase angle from the primary side 3 and secondary side 4 the elastomer coupling 1a certainly.

In addition, a high-frequency determination of the actually acting torque is possible. For example, this information can be transmitted to a - not shown - control and / or presentation unit.

Furthermore, the method for condition monitoring of the elastomer coupling or the dual-mass flywheel or the torsion damper can be controlled by a user interface, and comprise a representation of the characteristic curve and the associated characteristic values.

The rotational speed information or the rotational irregularities are respectively measured by a rotational speed sensor on the primary and secondary side of a clutch, an elastomer clutch, a dual-mass flywheel and / or a torsional damper. In addition to the speeds, for example, takes place on the primary and secondary side, a torque measurement.

Alternatively, it is also possible to calculate the secondary-side torque by means of the rotational acceleration to be calculated from the measurement of the secondary-side rotational speed and the mass moment of inertia of the secondary side to be entered.

On the basis of the speed and torque measurements, an evaluation unit calculates a characteristic, in particular in the form of torque via angle of rotation.

From the characteristic, for example, parameters for assessing the state of the clutch, the dual mass flywheel or the Torsionsdämpfers automatically calculated and evaluated in terms of condition monitoring.

In the method for condition monitoring of the elastomer coupling or of the dual-mass flywheel or of the torsion damper, this information is transmitted, for example, to a control provided by the customer and / or to a display unit in the form of a monitor, a display or a warning light.

The state monitoring process can also be used to optimize the ignition process by a comparative evaluation of the ignition process of a cylinder of an internal combustion engine. For this purpose, the primary-side torque measurement and / or speed measurement can be used for the evaluation.

Since the measuring system detects a torque load on both the primary and secondary side, the present invention advantageously makes it possible to make classifications and counts and to evaluate them accordingly.

In order to take into account the influences of the temperature, the frequency and (in the case of dual mass flywheels and torsional dampers) also the speed, for example, depending on these input variables, a sufficiently large number of reference characteristics as a function of the temperatures, the frequency and the speed over one Teaching phase to measure and save.

The speed and the frequency are independently and automatically determined by the evaluation unit or the sensor and / or can be entered. This can be, for example, an input of the number of cylinders or the main excitation, a calculated excitation frequency of a work machine, an internal combustion engine, or a generator. The temperature can either be measured by the unit or transmitted externally.
