The highly thermal resistant BVV freight carriage wheel for the block-braked wheelset

Strong, low compressive internal stress, future-proof

The BVV freight carriage wheel, which is highly resistant to thermal loads, is an exceptional long-lasting wheel that meets the high thermal requirements of freight carriages with composite pads. Of course, as with all members of the BVV wheel family, it is based on the proven manufacturing processes of the high-speed traffic range, such as the “Advanced Heating Technology AHT” and benefits from the long experience of our forging masters.

Light weight

Wheel disc in weight-optimised, low-stress design for the highest thermal loads

Low-noise

Low noise emission due to braking with composite brake pads

Durable

Optimized long-lasting characteristics achieved through specially heat treated treads

High availability

Longest runtimes are achieved by applying the proven manufacturing process from the high-speed traffic range

Variable

Individually manufactured according to customer requirements in standard or special grades and in all common sizes

Easy to service

The compressive internal stress, monitored in the wheel flange during operation is never exceeded

Design principle

1
BVV special grades for freight carriages – Block braked wheels made of ER7 according to EN 13262 optimised for high con-tinuous loads – Special quality: Niobium-based HHR5 for axel loads of up to 45 tonnes
2
Individually optimised forging temperature – Forging processes based on high-speed transportation wheels according to the proven BVV quality standard – Individually optimised for each alloy to maintain use under the toughest conditions
3
Advanced Heat Treatment AHT – The excellent long-lasting characteristics of our freight carriage wheels are ensured through the same process that gives our high-speed traffic wheels extra durability
4
Optional: Noise reduction Damping rings for damping rolling and curve travel noise
5
Variable dimensions – Wheel diameter from 630 to 1000 mm
6
Easy to service – BVV-grade materials, special shapes and optimised manufacturing processes ensure the longest possible maintenance intervals
