DESIGNING POSSIBILITIES
RESILIENT WHEEL
Light-weighting the rail industry is an ambitious goal that literally requires reinventing the wheel. Through the adoption of a worldwide service-proven design, patented materials and light-alloy components we are able to achieve mass reduction of the wheel while maintaining its performance and granting user-friendly maintenance activities.
LimoSet® innovative portal axle design for low floor LRVs has addressed two distinct objectives: reduction of the Total Life Cycle Cost of the wheelset and introduction of modularity concept that grants easy assembly, disassembly and inspection, and lower maintenance costs for the operators. Designed for urban application, it is lighter than the existing solutions.
Thermostable (i.e. “low-stress”) wheels designed to limit deformations and internal stresses caused by thermal loads during tread braking.
SOLUTIONS IN SAFETY
Lurshell® is the patented anti-impact shell for axles, protected by conventional anti-corrosion coating. The shell can be easily removed and remounted during periodical axle NDT inspection.
Innovative ultrasonic inspection probe for solid axles. The inspection is made from the blind hole designed at the end of the axle, allowing automatic and more reliable inspection of the entire axle in shorter time without the need to disassemble the wheelset from the train.
PROCESSES
COLD ROLLING
Cold rolling process for axles and sub surface area has shown to increase the fatigue limit by up to 20%, almost completely limit crack propagation and slow down the appearance of the corrosion. Cold rolling also allows to avoid non-destructive checks on subsequent wheel change.
MOLYBDENUM COATING
The application of spray coating of molybdenum on axle seats hardens the surface, making it resistant to scratches and damages during the wheels’ fitting and unfitting. It also increases a fatigue limit of the axle seats, boosting safety.
