Wagon of the train following a tunnelling machine

摘要

The trailer comprises a chassis with several wheels and two trays (30,32) installed symmetrically to the longitudinal plane of symmetry. There are means for measuring the possible inclination of the chassis about its longitudinal axis (XX'). There are liquid supply pipes (60,68,70) to the trays and sensors (38a,38b) for controlling the quantity of liquid in each tray as a function of the inclination measurement so that the quantity of liquid contained in each tray creates a return couple relative to the longitudinal axis to compensate for the possible inclination of the trailer.
