Benefits of technology

The invention is a method to measure and evaluate the relative movements of coupling elements in order to determine their condition and the extent of any damage. This allows for quicker detection of damage and replacement of damaged elements, without the need for revision. The method can also filter out unwanted movements that may not significantly contribute to damage. The accuracy of the method can be continuously improved through a learning process and influence on new developments of coupling elements.

Problems solved by technology

Coupling elements of a vehicle, such as spring elements or connecting elements, are subject to wear or ageing.
These three main causes result in an overall damage to the coupling elements, which differs for each coupling element.
In addition, the three main causes of the change in the material properties exhibit non-linear damage behavior, so that a prognosis of the overall damage to be expected is not possible.
It is also possible that coupling elements of a vehicle are in use which, on account of their overall damage, no longer satisfy the requirements.

Embodiment Construction

[0054]FIG. 1 is a schematic illustration of an exaplary coupling element 1 formed as a coil spring. For the coupling element 1 to be monitored, a significant relative movement direction 2 is determined. A sensor 3 and a slave 4 are fixed to the component 9. The distance between the sensor 3 and slave 4 can be varied in the significant relative movement direction 2. For instance, this distance is enlarged by tensile forces exerted on the coil spring in the significant relative movement direction 2 or reduced by pressure forces exerted on the coil spring in the significant relative movement direction 2. If the coupling element 1 executes relative movements in the direction of the significant relative movement direction 2, the sensor 3 and / or the slave 4 therefore also execute these relative movements. Its distance along the significant relative movement direction 2 at least changes. Relative movements of the coupling element 1 to be monitored along the significant relative movement di...

Abstract

A method and device for monitoring coupling elements of a vehicle, according to which at least one representative direction of relative movement is determined for a coupling element to be monitored, relative movements in the representative direction of movement of the coupling element to be monitored are measured and stored, and the stored relative movements are then evaluated such that the coupling elements can thus be monitored and their suitability for use in a vehicle can be determined.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This is a U.S. national stage of application No. PCT / EP2014 / 052231 filed 5 Feb. 2014. Priority is claimed on Austrian Application No. A50104 / 2013 filed 12 Feb. 2013, the content of which is incorporated herein by reference in its entirety.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The invention relates to a method and a device for monitoring coupling elements of a vehicle.[0004]2. Description of the Related Art[0005]Coupling elements of a vehicle, such as spring elements or connecting elements, are subject to wear or ageing. Neither the wear nor the ageing of the coupling elements during operation of the vehicle can be prevented with the current prior art. These coupling elements must therefore be replaced at regular intervals or after a certain number of vehicle kilometers within the scope of a revision. The wear or ageing of such coupling elements has an influence on their material properties. Three main causes of t...
