SUSPENSION DEVICE Russian patent published in 2018 - IPC B60G17/15 B60G13/14 B60G17/16 B60G13/18 B60G17/06 

FIELD: machine building.

SUBSTANCE: invention relates to a suspension device. Suspension device contains a spring, an electric motor, a power consumption circuit and a load control section. Spring is provided between the upper element and the lower element. Electric motor is provided related to the spring and configured to generate power in accordance with the speed at which the movable shaft operates. Movable shaft is movable in accordance with the actions of the upper element and the lower element in the direction of expansion and compression of the spring. Power consumption circuit includes a load control circuit that is configured to generate a damping force in the electric motor by using the energy generated in the electric motor and vary the damping force. Load control section is configured to control the load control circuit such that the power consumption by the load control circuit increases with the speed of the moving shaft.

EFFECT: possibility of increasing the damping force in the speed range in which the damping force is saturated due to the characteristics of the electric motor.
