Abstract: Disclosed is a rig (1) for testing an automatic underground train (2), including at least two rolling units (8) at a distance from each other, each one provided for rolling at least one wheel (6) of the train (2) thereon, each unit (8) including: a rotary inertial body (28); a motor (26) engaged with the inertial body; and a sensor (51) for the rotational speed of the inertial body; the rig also including a unit (11, 15) for controlling each of the motors (26) so as to permanently eliminate any difference in speed between the rolling units.
Abstract: Disclosed is a rolling unit (8) for a test rig (1) for testing an automatic underground train, including: two rolling belts (27), each one provided for a wheel (6) of the train to roll thereon, the wheels driving the movement of the belts; and a rotary inertial body (28); each belt including: a pinion (31) that is rotatably connected to the inertial body; two rollers (33); and a grooved rolling surface (32) mounted on the rollers, meshed with the pinion, and forming a rolling area (34) for a respective wheel between the rollers.
