SUBSTANCE: invention relates to single-axle vehicles with body stabilisation effected by means of a moving mass and gyros. The outer frame lengthwise half-axles accommodate an inner frame, one of the said half-axle being linked to the inner frame stabilisation motor. A bearing platform is rigidly attached to the inner frame to carry the load and to accommodate a flywheel so that the bearing platform centre of inertia is arranged above the wheel pair running half-axles. The inner frame accommodates, also, two bi-degree gyros and a balance weight. The flywheel arranged on the platform represents a motor connected to the control unit, the motor axis of rotation being parallel to the wheel pair running half-axles. The flywheel rotation speed increment is inversely proportional to the vehicle speed increment.

EFFECT: higher reliability and accuracy of stabilisation of the bearing platform at wider range of its angular travel.
