The resilient BVV wheel with element-shock absorber, three part design

The most successful wheel concept for local public transport

BVV wheels with element shock absorber define the worldwide standard for resilient wheels on the normal route. They are safe, comfortable and gentle on vehicles, travel routes and adjacent buildings. Mileage and operating toughness are extremely high, the service is exemplary. Accordingly, customer satisfaction and worldwide acceptance are correspondingly high. The design principle, in which specially fitted rubber elements decouple the wheel tyre from the wheel rim and spring the construction, has been identical for all our normal-suspension wheels since Bo 54, the prototype of the globally successful resilient Bochum wheels. The three-part design with wheel rim ring is a further development especially for simplest mounting and servicing.

Torsion-proof element shock absorber with high primary stress as well as fatigue-resistant tyres and rubber elements which ensure trouble-free operation


On track and carriage concept with individually tuned suspension behaviour

Easy to service

Maintenance-free rubber elements, tyre changing and fast and easy assembly

The design principle

Easily by specially hardened steels Use of high strength special steels for wheel body and wheel rims. Design and materi-als are designed for longevity and weight reduction
Simple assembly During assembly of the rim ring, the rubber elements are simultaneously brought into their installation position by means of simple workshop equipment. In the end position, the rim ring is fixed by means of a press connection and the construction principle of the screw-less wheel is retained as with the two-part BVV wheels with element suspension
Non-rotating rubber elements – Individually designed rubber elements with special long-life rubber compound for max-imum durability over the entire service life – Non-rotating due to high primary stress and tailor-made cut
Matched suspension behaviour – Vertical deflection, individually tailored to tracks and carriage concept up to mm 1.2 mm with 60 kN wheel force
Route protection – Reduced unsprung masses reduce wear and tear to the vehicle and track system and prevent oscillations and shocks in adjacent residential areas
Integrated noise damping – Significant noise reduction through the decoupling of wheel tyres and wheel rim by rubber element shock absorber with special rubber
Long-lasting tyres made of special steel – Wheel tyres in the tried and tested N, H or SO Excelsior grades reduce wear and fa-tigue damage and guarantee maximum mileage – Optional: Standard quality according to UIC and ASTM
Optional: High-performance absorber – Individually tuned high-performance absorbers reduce noise caused by going around bends by up to 30 dB (A) – Maintenance-free BVV mounting system
15 tonnes and more per wheelset – Designed for high continuous load and high axle loads
Extended safety concept – Additional limiting shoulders can be used to limit the cross spring deflection, even in the case of extraordinary loads
Current bridges – Specially designed current bridges for safe power transmission between wheel rim and wheel tyres

Selection of previously manufactured wheel types

Bo 84, Bo 2000, Bo 06

In these types of wheels, a wheel rim ring – frictionally connected to the rim by a tapered press-fit joint – ensures that the rubber elements are seated securely against rotation. The particular advantage of this design is the simplified assembly/disassembly of the wheel tyres, for example directly on the vehicle to reduce maintenance costs.

Additionally, the screws serve only as an additional securing element. The transmission of the service stresses is carried out by the conical press-fit joint.

Wheels which are fundamentally the same type differ mainly in terms of load capacity and the different spring stiffness.

How should we construct your wheelset?

Each track and carriage format poses different challenges to wheels and wheelsets. Therefore, the wheel types shown are not a standard offer to which you need to adapt, but specimens that you can individually design together with us and expand even further.
