A method for actuating a track conditioning unit or a wheel flange lubricating system of a rail vehicle. The track conditioning unit provides auxiliary agent to sub-regions of a rail on which the rail vehicle is travelling, in order to increase friction between the wheel and the rail. A wheel flange lubricating system provides a fluid to a wheel sub-region of the rail vehicle or to a rail sub-region, in order to reduce friction between the wheel and the rail. A relative movement between a railcar body and a bogie of the rail vehicle is detected using path measurement, in order to detect a bend in the track. Based on the path measurement, the track conditioning unit or the wheel flange lubricating system is actuated in a targeted manner according to the bend, such that the auxiliary agent or fluid is applied in a resource-saving yet effective manner.

Device to avoid the aquaplaning problem on a vehicle (10), the device being applicable at least on the drive wheels (28) of the vehicle and including a tank (12) of fluid under pressure that is connected to a plurality of fluid ejectors (26) associated with the respective wheels and suitable to shoot jets of pressurized fluid onto the road surface, and sensors (18) suitable to detect the conditions of the road surface to actuate the fluid ejectors. The fluid ejectors (26) are injector nozzles controlled by a central processing unit (CPU), which receives the signals from the sensors (18), and are operated in a manner coordinated with the physical position of the respective wheel so as to be continually oriented in the direction of travel of the same wheel.

A method for controlling a device for metering granular material and a metering device for metering granular material comprises a feed for the granular material from a container into a metering chamber. A metering piston can be actuated by a control device such that a gap between the feed and the metering chamber is opened by a predefined first distance and a second distance which is greater than the first distance. At least one sensor is arranged in a delivery line leading away from the metering chamber and is connected to the control device so that the metering piston can be actuated for a predefined duration such that the gap between the feed for the granular material and the metering chamber can be opened by the second distance if a blockage of the granular material is detected by the at least one sensor, so that the blockage is dispersed.

An integrated abrasive dispensing material system for a wheeled vehicle is provided. The system having a hopper for dispensing the abrasive material into a dispenser, and then out dispensing pipe at the bottom of the dispenser. The dispenser has a rotating brush roll actuated via a motor, the rotating brush roll having a plurality of bristled flaps extending radially from a cylinder positioned inside the hollow dispenser. The flaps ensure a constant and calculated flow of abrasive material. The flap also make contact with the interior perimeter of the dispenser keeping the abrasive material inside the dispenser in an environment that prevents moisture and cold air flow from entering the dispenser which could cause the abrasive material to form blocks that could jam the system.
