ANTISTRIKE DEVICE Russian patent published in 2023 - IPC B60R19/32 F16F9/53 

FIELD: vehicles.

SUBSTANCE: devices designed to absorb impact energy in a collision, namely, passive safety systems for vehicles used in multi-axle chassis. The antistrike device comprises a bumper connected to the left side member of the first linear guide, and to the right side member - to the second linear guide. On the left member there is a rear swivel mount of the left hydraulic shock absorber, equipped with a return spring, on the right member there is a rear swivel mount of the right hydraulic shock absorber, equipped with a return spring. The bumper is provided with a first hinged attachment for the left shock absorber rod and a second hinged attachment for the right shock absorber rod. Left, central and right shock sensors are mounted on the bumper, and a controller and an electrochemical energy storage device are installed on the left side member, in addition, the left and right shock absorbers are double-sided adjustable magnetic fluid shock absorbers equipped with return springs, and the pistons contain three magnetorheological throttles each, axles which are placed at an angle of 120° with respect to each other, while the above magnetorheological throttles are magnetic field inductors placed around the throttling channel. The piston and rod cavities of the shock absorber are filled with a ferromagnetic suspension.

EFFECT: increase in the level of protection of the crew and cargo, as well as increase in the efficiency of absorption of impact energy when the vehicle collides with an obstacle.
