Traction Motor Boots for Railway Vehicles

Traction motor boots are customised products that adapt to the individual movement profile of the particular vehicle. The connections are designed according to the installation situation on the wagon body or the bogie.

The connections (flanges) of the folding bellows have circumferential sealing surfaces. Vulcanised flanges attached to the folding bellows ensure a self-sealing connection. The design of the bellow is customised and developed based on the assembly dimensions and movement requirements. Furthermore, the required air flow and pressure loss are taken into account during the design phase of the product. The defined geometries are moulded on specially designed tools and tested as required. Moreover, the folding bellows can be stabilised with wire rings if necessary according to the operating requirements.


  • Specific fold geometry, tailored to the movement profile
  • Individual mounting and installation systems
  • Ultra durable and field-proven

The maximum stipulated movement of a bellow for a new project is simulated with testing facilities. The long-term durability of the traction motor boot can be tested before the start of serial production by calculation in testing facilities with pre-defined movement matrix over a defined period of time. Thereby the wear behaviour with various installation lengths and deformation sequences can be tested as well.
