Roller mount for track-guidable buses

摘要

The invention relates to a roller mount for track-guidable buses in which a predetermined break point or predetermined deformation point is provided for the mounted track-guiding roller. A deformation sensor which also breaks when the predetermined break point or predetermined deformation point breaks or is deformed is laid over this point. A conductor which is mounted in an electrically insulated fashion is accommodated in the deformation sensor and in the case of deformation it tears and thus makes it possible to signal triggering of the predetermined break point or predetermined deformation point in the field of perception of the driver of the vehicle. In order to be able to apply such a deformation sensor quickly and in an operationally reliable manner, a bore hole which traverses the predetermined break point or predetermined deformation point is provided in the roller mount. The deformation sensor which is of pin-shaped design is inserted with little play into the said bore hole; the said deformation sensor itself consists of a brittle breakable element in which or on which the electrical conductor is provided. For a plug-in connection which can be clamped and rotated in a positively engaging fashion, the bore hole which receives the deformation sensor expediently extends over the fitting surface gap of the plug-in connection so that in the event of the clamped mount becoming maladjusted the deformation sensor is sheared off. Various possible embodiments of the deformation sensor, in particular the electric conductor, are described.
