WELCOME TO THE
HOUSE OF SAFETY AND COMFORT
Safety and comfort of passengers represent the main concern in rail traffic. Sumitomo Riko offers the best-in-class systems and components to reduce vibrations and noise in order to safeguard people, materials and the environment.
HYDRAULIC PRIMARY SUSPENSION
Optimized Durability and Comfort
The hydraulic primary suspension damps vibrations and reduces noise. The self-contained hydraulic system is incorporated into the conical spring to assure optimum characteristics and reduced maintenance.
- Multidirectional spring suspension
- Hydraulic damping of vertical vibrations
- Coordinated longitudinal and transverse stiffness in order to optimize wheel set guidance
- Compact design with low maintenance
- Suitable for older rolling stock to comply with modern comfort and environmental demands
NEW MATERIAL SOLUTIONS
Innovation You Can Feel – Supporting Safety and Reliability
» Optimization of the Settling Behaviour
Vibration control components in rail systems are exposed to extreme forces. Due to our optimized mixtures for various areas of application, they retain their shape and do not "set".
» Low Temperature Compounds
To prevent the “vitrification” of elastomers at low temperatures, we offer blends up to -60°C so that they keep their vibration properties.
» Fire & Smoke Compliance
According to the directive EN 45545, future components on fire and smoke conformity must be interpreted. Our compounds meet these requirements reliably.
OPTIMUM FUNCTION USING MINIMAL SPACE
Optimum Function Using Minimal Space – Compact Design Supports NVH Behaviour
Integrated systems in the area of primary suspension enable a compact design of components that allows a flexible adaptation to the NVH characteristics of the train system.
» Primary Suspension with Integrated Coil Spring
Optimized compact system with three different stiffness characteristics and acoustic insulation
» Coach Connection
Higher operational reliability of the tram up to the high-speed train
» Low Conical Stiffness Spring Seat
Improvement of helical spring lifetime
