FIELD: transport.
SUBSTANCE: invention relates to automotive industry. Proposed device is equipped with steering mechanism with booster. Steering mechanism comprises steering wheel differential gearing to transmit wheel turn angle from input shaft and wheel turn angle overlaid on wheel turn angle by adjusting means. Transmission of steering wheel turn angle in steering gearing is ensured by gearing stage (a, b, c, d). Decrease in steering wheel turn angle allows manual control over truck at failure of steering mechanism equipped with booster. Truck steering device comprises above described active steering mechanism.
EFFECT: higher safety, better controllability.
