FIELD: transport.
SUBSTANCE: claimed under frame comprises mounted axles (1) with wheels (3, 4) rigidly fitted on axles (2). The wheel of every mounted axle incorporates the electromagnetic clutch (5) electrically connected with the appropriate transducer (6) arranged at underframe structure (7) to respond to the change of angle (α) between the mounted axle geometrical axis (8) and crosswise geometrical axis (9) if the underframe structure.
EFFECT: ruled out wear of mounted axle hubs and contact surface of wheels and rails.
