FIELD: transport.
SUBSTANCE: commercial car with four-wheel truck includes controlled rigid axle and control device. Rigid axle is movably connected with frame, body and top structure of vehicle by means of control device. Control device includes at least one actuating unit. The actuating unit is made capable to control rigid axle movement relative to frame, body and top structure. Control of movement occurs depending on at least one vehicle operational parameter recorded by sensory unit. The sensory unit contains at least one vibration transducer made capable to record vibrations of at least one part of vehicle and to perform transmission to control unit. The control unit is made capable to generate control signal based on recorded vibration and to send this signal to actuating unit. Based on this signal, the rigid axle is actuated by actuating unit in such a way that created due to rigid axle motion vibrations at least partially compensate for recorded vibrations of at least one pert of vehicle.
EFFECT: possibility to compensate for vibrations occurring during motion in frame, body or top structure.
