Abstract: A device for the application of lubricant onto the running surface of rails for rail vehicles includes at least one dispensing nozzle for issuing out a lubricant, and an air nozzle provided above the dispensing nozzle and aligned to blow out air in a direction of an upper edge of the dispensing nozzle and a railhead. The dispensing nozzle extends upwardly on an outer railhead surface which is distal to a contact surface for a rim of a running wheel of the rail vehicle.

Abstract: The invention is directed to a method for controlling the delivery of lubricant between two parts which are movable relative to one another, in particular for lubricating rails, above all on curved tracks, in order to prevent or reduce squealing noises, wherein at least one sensor, e.g., a microphone, is provided for picking up sound vibrations, particularly structure-borne sound vibrations, the signal of the sensor being fed to a selective amplifier, e.g., an active bandpass filter, and used as an actuating variable for initiating the delivery of lubricant. For this purpose, at least two frequency bands are filtered out, the intensity of the sound vibrations of the filtered frequency bands is compared, and the determined difference or the ratio of the determined values is used as an actuating variable.

Abstract: The invention is directed to a device for distributing lubricants in grooved rails, particularly for railborne urban traffic. An elongated plate is provided which can be arranged in the groove of the rail and which is provided with cutouts at least along one longitudinal edge, but preferably along both longitudinal edges. The cutouts start at the longitudinal edge and are accordingly open-edged. The lubricant can be supplied to these cutouts. The open-edged cutouts of the plate are covered by a cover plate which is constructed so as to be elastic at least in the covering area.

Abstract: The invention is directed to a device for distributing lubricants in grooved rails, particularly for railborne urban traffic. An elongated plate (6) is provided which can be arranged in the groove (10) of the rail (1) and which is provided with cutouts (22, 23) at least along one longitudinal edge, but preferably along both longitudinal edges (24, 25). The cutouts (22, 23) start at the longitudinal edge and are accordingly open-edged. The lubricant can be supplied to these cutouts (22, 23). The open-edged cutouts (22, 23) of the plate (6) are covered by a cover plate (7) which is preferably constructed so as to be elastic at least in the covering area.
