Reduced unsprung mass, reduction of vibration and noise, easy replacement of wheel tyres
GHH-VALDUNES proposes a wide product range of rubber-sprung wheels, based on the experience of more than 75 years and 120’000 wheels supplied in very different applications, from light rail to heavy haul locomotives:
- The SAB V-Wheel family (V15 - V30 - V60).
- The SAB Resilient Disc Wheel.
- The VUT™ Wheel.
Running comfort, for the passenger, the resident, the vehicle and its track
Proven by field measurements or positive customer ratings. GHH-VALDUNES resilient wheels provide a very efficient reduction of shocks and vibrations. With their low radial stiffness, the SAB Resilient Wheel or the VUT™ wheel can replace a primary suspension or accommodate specific bogie designs, e.g. direct motor drives.
Key benefits of GHH-VALDUNES solutions
Tailor-made solutions, because each project is unique. Specifics like: small diameter, high wheel load, thermal impact from block brake are adapted
to each project.
Maintainability, because service costs must be minimal
One common feature for all our wheels: a split design. Three steel parts: a wheel tyre, a wheel body and a wedge ring. In between, some pre-stressed rubber elements: rubber pads, or, alternatively, one rubber ring or two rubber rings. Result: a very easy replacement of tyres and rubber elements, with only conventional tools.
Noise reduction
GHH-VALDUNES resilient wheels decrease rolling noise and squealing noise in curves. In case of additional requirements, GHH-VALDUNES proposes customised noise absorption systems, like rings, absorbers or shields, mounted on the wheel tyre.
