Abstract

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.
