OSCILLATION DAMPING DEVICE Russian patent published in 2018 - IPC F16F7/02 F16F13/04 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to mechanical engineering. Device comprises rods and a body interacting through non-self-locking screw kinematic pairs. Internal cavities of the body are filled with hydraulic fluid and communicate via throttling channels. Rods are placed in two parts of the device and, with the supporting surfaces of the interacting parts of the vehicle structure, form cylindrical kinematic pairs and the screw non-self-locking kinematic pairs having right and left threads, respectively. Cylindrical cups are connected by the bushing of a cylindrical sleeve. Said sleeve forms a rigid self-locking screw connection having right and left threads, respectively, with the side surfaces of the cups. Throttling channels are located along the screw lines of kinematic pairs. Surfaces of the sections of the thread profiles are the walls of the throttling channels.

EFFECT: higher efficiency of energy dissipation.
