Wheel flange lubrication

The wheel flange lubrication is designed to lubricate friction points between the wheel and the rail of railway vehicles. The wheel flange lubricationsystem supplies lubricant to the wheels via a specific centralized lubrication system, mainly during outward and inward curves.

The curve sensor transmits a corresponding signal for left or right curves to the control panel of the wheel flange lubrication system.

The wheel flange is an approximately 1.5-inch high vertical bead, which is located on the center of the rail and directed toward the side of the wheels of modern rail vehicles. With the help of the wheel flange of the rail vehicle, the track is defined, within which the railway vehicle can move in the transverse direction. 

Generally, a wheel flange lubrication system consists of a lubricant reservoir, a lubricant filter (if required) and the actual spray nozzle which sprays the lubricant with the aid of compressed air to the wheel flange.

The spray intervals are determined by controlling and timing the compressed air, which can be continued idefinitely after a short pause. 

The precise quantity of sprayed lubricant, the variable spray frequency and the adjustment of the spray jet are essential components for ideal wheel flange lubrication. 

For lubrication ofthe tooth flanks of large, low-speed, open gear drives, wheel flange lubrication is also ideal.

• Very little lubricant quantity is needed and the application is extremely precise.
• Wear reduction on wheel and rail, as well as energy savings by friction reduction and a considerable decrease of noise
• Reduction of maintenance time for the parts being lubricated
• Reduction of maintenance costs (machines and men power)
• Less lubricant consumption through exact dosage, which also contributes to environmental protection..
