Wheel Flange Lubrication and Rail Head Maintenance Systems

The FluiLub rail maintenance systems bring an end to the squealing noise of rails in narrow curves and efficiently reduce the wear of wheels and rails.

The FluiLub system is developed for using thixotropic lubricants with high solid contents, achieving an ideal combination of adhesion and flowability in a spray lubricant for high-stress applications. The system is installed mainly on the leading vehicle axle. Due to the lubricants used, the lubricant is transferred to the following railheads or wheel flanges.
Types of Rail maintenance:
1. Rail Head Maintenance
2. Wheel Flange Lubrication
Rail Head Maintenance
The Fluilub railhead maintenance system is an on-board system where a special railhead maintenance care product is being sprayed directly onto the wheel or rail. Due to the lubricants used, the lubricant is transferred to the following wheels and brings an end to the squealing noise of rails in narrow curves.

The activation of the railhead maintenance system happens curve-dependant. The pump is activated until the curve signal drops. A conveying process consists alternately of spray time and break time.

Spray nozzles for railhead maintenance

Spray nozzles slightly moisten the railheads with a highly adhesive lubricating film, which is transferred to the following wheels by contact with the rails. The FluiLub spray nozzles guarantee the distribution of the railhead maintenance the fluid of the railhead even with very high velocities, without polluting other components like the brakes.

The spray nozzles for railhead maintenance are available in two standard versions; straight and angular. This offers you the best options for installation, taking into account the installation space

Benefits
- Improved efficiency and lower costs
- Improved environmental impact - Reduces noise
Wheel Flange Lubrication
The Fluilub wheel flange lubrication system is an on-board lubrication system where the special lubricant is being sprayed onto the wheel flange. Due to the lubricants used, the lubricant is transferred to the following wheel flanges and reduces the wear of the wheels and rail.

The activation of the wheel flange lubrication system happens on time, distance or curves.

Spray nozzles for railhead maintenance

Benefits
- Improved efficiency and lower costs
- Improved environmental impact - Reduces noise
Compressed air transports the lubricant along the interior tube walls to the lube point. The special mixing distributor divides the lubricant precisely into the different lube pints.

Spray nozzles slightly moisten the wheel flange with a highly adhesive lubricating film, which is transferred to the following wheels by the contact with the rails and which cannot be thrown off even with very high speed. The whole process is controlled by an electronic control or the control unit of the vehicle.

Innovative wheel flange lubricants with high solids content guarantee reliable lubrication even with extreme temperature variations. This reduces noise and wear – proven by many applications.

The FluiLub mixing distributor

The patented splitting insert of the FluiLub mixing distributor divides the lubricant. A porous insert collects the liquid particles, splits them up to tiny droplets and distributes them like a drizzle to the airstream.

This principle guarantees a homogeneous mixing ratio even with several spray nozzles.

The FluiLub spray nozzles

The FluiLub spray nozzles guarantee the lubrication of the wheel flanges even with very high velocities, without polluting other components like the brakes. The design of the spray nozzles depends on the application.

The FluiLub control unit

The FluiLub system is controlled by an electronic control unit. The compact and rugged controller allows the optimum adaption of the wheel flange lubrication to the operating conditions.

The optional curve sensor allows the curve-dependent control of the system.

Directional valve

The directional valve is required for the curve-selective activation of the system. It can be installed directly at the pump reservoir or externally. With this option, each wheel
flange or rail can be supplied separately with lubricant or rail head maintenance fluid as required.
