Cartridge to railway industry

Bespoke cartridge to articulate seats (French TGV)

A French leading manufacturer of seats for the railway industry had to develop a mechanism to articulate and automatically maintain a tray in the raised position with a dampened opening for 1st and 2nd class passengers. The application was for the French TGV 3G.

The specification was particularly restrictive:

  • Reduced available volume.
  • Important number of cycles (30,000 opening / closing cycles).
  • Silent in operation.

No maintenance service.

  • Capitalisation of experience for future requests

Material:

  • Housing, piston and head : sinter steel with heat treatment
  • Screw and nut adjustment: 8.8 grade steel
  • Spring washers: spring steel
  • Anti-squeak washer: zinc plated steel with Teflon coating
  • Weight: 80 g

Fixing and mounting:
