A device and method for dispensing a friction-coefficient-optimizing mixture of at least one lubricant and at least one grit into the gap between a rail wheel of a rail vehicle and a rail. The device includes a reservoir for the lubricant, a reservoir for the grit, a metering unit for metering the lubricant, a metering unit for metering the grit, a delivery apparatus for delivering the lubricant, a delivery apparatus for delivering the grit, and a common dispensing nozzle. The apparatus for delivering the lubricant and the apparatus for delivering the grit are separate from each other and end in the common dispensing nozzle, the friction-coefficient-optimizing mixture therefore not being formed until the dispensing, and an additional compressed air line is provided, which ends in the common dispensing nozzle.

The invention relates to a sanding system for a rail vehicle with a grit container, with a conveying device and with a feeding device. The grit container contains a grit. The grit passes from the grit container into the conveying device and from the conveying device into the feeding device. The feeding device is configured in such a way that the grit can be introduced in a targeted manner into a wheel region and/or into a rail region of the rail vehicle. The conveying device has a driven conveyor worm which rotates about a longitudinal axis and by way of which the grit passes from the grit container into a conveying chamber. Compressed air can be introduced into the conveying chamber, in order to transport the grit from the conveying chamber into the feeding device.

A combined track conditioning unit includes a dispensing apparatus with an outflow opening integrated in the front region of the dispensing apparatus which is suitable for applying a gaseous drying medium to a rail. A gritting material outlet unit which is integrated in the rear region of the dispensing apparatus and is suitable for applying a gritting agent to the rail also forms part of the dispensing apparatus. A rail vehicle is also provided. Additionally, a method for increasing a coefficient of friction between a rail and a wheel of a rail vehicle with the aid of a track conditioning unit is provided.

A sanding system for a rail vehicle includes a housing of a cellular wheel sluice having an inlet located at the top and an outlet located at the bottom, a pivotably mounted cellular wheel having a plurality of cells, and a motor that is coupled with the cellular wheel. The sanding system further includes a container connected to the inlet of the cellular wheel sluice for receiving brake sand, or a feed line connected to the inlet of the cellular wheel sluice for transporting brake sand, and a discharge line connected to the outlet of the cellular wheel sluice for transporting brake sand. The motor for driving the cellular wheel is thereby arranged above the inlet.

A locomotive sanding system is described for conveying sand from a sand tower to a sand box mounted on a locomotive. The invention is designed to prevent personnel from being subjected to sand and sand dust during the sand box being filled with sand from the sand tower. The system includes a universal sealing nozzle which may be used with the locomotive sanding system or other devices. The universal sealing nozzle includes an expansion seal extending therearound which may be moved from a retracted position to an expanded position. When the nozzle is inserted into the fill pipe of the sand box, the expansion seal is expanded to sealably engage the inside surface of the fill pipe.

A rail conditioning system associated with a locomotive is provided. The locomotive operates on a rail. The rail conditioning system includes a fluid supply tank. The rail conditioning system also includes a first nozzle coupled to the locomotive. The first nozzle is adapted to direct a first beam of fluid received from the fluid supply tank towards a first portion of the rail. The rail conditioning system further includes a second nozzle coupled to the locomotive. The second nozzle is adapted to direct a second beam of fluid received from the fluid supply tank towards a second portion of the rail. The rail conditioning system includes a valve element provided in fluid communication with the first and second nozzles. The rail conditioning system further includes a control module in communication with the valve element.

A system and method herein relate to vehicle control by adjusting a torque distribution of the vehicle. The system includes a first motor configured to provide a torque to a first wheel, and a delivery system configured to controllably apply a traction control compound to a route on which the first wheel is configured to travel. The system also includes a controller circuit having one or more processors. The controller circuit is configured to control the delivery system to apply the traction control compound to the route based on a monitored temperature of the first motor.

A sand spreading system for a rail vehicle with driveable and/or brakeable rail wheels. The sand spreading system includes a sand box for storing spreading sand, a sand staircase which is fastened to the sand box for the compressed-air-controlled metering of the output of spreading sand, and a sand outlet tube which is connected to the sand staircase via a sand hose and opens in front of a rail wheel. By a heating device for generating a hot air flow passing through the spreading sand being integrated in the sand staircase, the spreading sand can be kept dry and pourable even in the wet and frost, and therefore the function of the sand staircase and hence the effective operation of the rail vehicle are assured.

A device for spreading granulate, particularly for spreading sand into the gap between a rail and a wheel of a rail vehicle, includes a housing, at least one inlet for the granulate and at least one outlet for the granulate, an axially movable metering piston and a compressed air connection, which leads into a pressure chamber and serves for actuating the metering piston by compressed air to meter the granulate. At least one bore is provided in the metering piston. To create a device which is of particularly simple and compact construction, a conveying air chamber separated from the pressure chamber and has a compressed air connection is provided, and at least one bore in the metering piston connects the conveying air chamber to the at least one outlet for the granulate, such that granulate can be conveyed to the at least one outlet by compressed air independently of the metering process.
