The stress-balanced BVV monobloc wheel for multiple unit trains, lo-comotives and passenger cars

The endurance runner for all speeds below the high-speed transportation range

With the BVV monobloc wheel for passenger transport, we present a balanced wheel concept for the speeds demanded of high mileage performance. Like all members of the BVV wheel family, it benefits from the tried and tested materials and manufacturing processes of the high-speed transportation sector, especially the “Advanced Heat Treatment AHT” for outstanding long lasting properties. A quality wheel produced from quality German blacksmithing!

Light weight

Low weight due to the stress-balanced wheel disc with evenly distributed load over the entire wheel disc area

Low-noise

Reduced natural oscillation and noise emission due to the stress-balanced form; optional-ly available with wheel noise absorber for further noise reduction

Durable

Optimised long lasting properties achieved through specially heat treated treads and me-chanical anti-imbalance treatment

High availability

Longest run times with minimal downtime due to high-tech materials

Variable

All wheels are individually manufactured in standard or special grades and in all common sizes

Easy to service

Wheel discs can be tested comfortably from the tread using ultrasound

Design principle

1
Stress-balanced wheel disc – The straight, particularly weight-saving design of the stress-balanced wheels is a BVV invention – It significantly reduces natural oscillation and noise emission and simplifies maintenance and service
2
Materials in special BVV quality – All standard grades according to international EN, JIS, AAR, GOST and UIC standards, manufactured and specially treated according to the BVV treatment method for extended running times (AHT) – We recommend excellent quality BVV special steels for trouble-free continuous operation
3
Individually optimised forging temperature – Exactly matched to the respective alloy, we set the optimal forging temperature – The many years of experience of our master blacksmiths and state-of-the-art technology ensure the longest service life, even under the most difficult conditions
4
Advanced Heat Technology AHT – The outstanding long lasting properties of our passenger and locomotive wheels are en-sured by special heat treatment (“Advanced Heat Treatment AHT”) – The even circumfer-ential strength of the treads provides optimal strength and wear in relation to the structure – It is the same process that gives our high-speed transportation wheels their special re-sistance
5
Exemplary noise damping – Especially recommended for locomotives: lightweight, highly efficient radial sound ab-sorbers with which the start-up sounds are effectively suppressed – Even rolling and curve travel noises are significantly reduced – They are also maintenance-free thanks to the tried and tested BVV special fastening
6
Variable dimensions – Wheel diameter from 630 to 1400 mm
7
Suitable for US-Service – The wheel disc is checked quickly and easily via the tread – The straight design of the wheel disc makes this process possible
8
Optimised for maintenance – Minimal tread damage and low-maintenance operation thanks to the BVV production pro-cess and material selection
