Over 150,000 wheels in service in the world
Wheel especially designed and developed for operations under high thermal stresses. Low stress level in the rim and reduction of rim deflection. Decreased maintenance downtime through increased wheel life and quality impovements. 100 % conformity with new European standards: EN 13979-1, EN 13262 and TSI.
Background
Due to high residual stress on traditional ORE freight wheel rim, failures appeared, especially after drag braking on mountain lines. The VMS® concept was developed to solve the problem and thus increase safety levels.
Solutions
- New low stress geometry designed using CAD & FEA (from 730 to 1000 mm diameter).
- UIC approved and/or Railway technical qualification.
- Efficiency checked on bench and/or through field testing.
Results
- 30 % greater resistance against catastrophic brittle fracture.
- 50 % reduction of the lateral rim displacement.
- Absorbed braking power up to 50 kW for 45 min.
- Noise reduction with a composite brake shoe.
Benefits
- Improved safety.
- Increased wheel life.
- Reduced downtime.
- Reduced life cycle cost.
- Improved braking performance.
- Noise reduction available.
