Abstract
A drive unit for rail lubricating devices and a method for using the same solves the problem of the using impact of rolling stock wheel to drive lubricating device, and preventing or mitigating peak caused by impact and resulting pressure overload or uncontrolled application of the lubricating medium in different climatic conditions or at different external temperatures by using the impact of at least one wheel of rail vehicles via the pivoting lever (also described as a rocker arm) and the inertia of this motion to operate the lubrication device in such a way that it changes the kinetic-potential energy of the rolling wheel impact into torque without the help of added hydraulic fluid and without creating a negative pressure for the purpose of pushing the medium or dosing.
