Solid friction modifiers for rail head crown (TOR)
- Reduces wear on the wheel tread
- Reduce energy/fuel consumption
- Does not affect traction and braking
- Do not pollute the environment
- Non-flammable
To reduce wheel tread wear, a rigid friction modifier is designed to maintain the coefficient of friction between the wheel tread and the top of the rail head at around 0.3.
As a result, lateral forces in the wheel/rail contact are reduced, and thus the formation of wavy rail deformations, the flaking of material particles from the wheel tread and noise are reduced.
The dimensions of the friction modifier and its applicator must be selected according to the nature of the operation, free space and maintenance schedule. An assessment of the technical requirements is essential for the design of the solution.
