FIELD: transport.
SUBSTANCE: invention relates to automotive industry. Protective device comprises front and rear parts, adjusting mechanism connected to appropriate part and drive elements to change relative position of parts by means of adjusting mechanism. Protective device comprises stiffening means to lock every part relative to each other to exploit the mass of both front and rear parts. Vehicle structure stiffens when acceleration and/or speed of one of its parts exceeds limiting values. This occurs at blast of mine under this vehicle. Control over stiffening means of said protector consists in placing the pickup in one of vehicle parts. Said pickup determines said acceleration and/or speed to transmit appropriate signal to control device attached to said stiffening means. Control device guides stiffening means for locking of relative position of vehicle every part.
EFFECT: damping of external shock effects.
