VIBRATION INSULATION SYSTEM OF THE VEHICLE BOGIE Russian patent published in 2018 - IPC F16F15/67 F16F7/10 F16F7/04 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to mechanical engineering. Object of protection, which has two degrees of freedom, rests with its both ends onto the elastic elements, which are connected to the base. Object of protection is hingedly fastened with its upper ends onto the L-shaped lever arms, which rest with one arm onto the elastic elements that are connected to the base. Other two arms are connected between each other with the spring. Elastic elements are located symmetrically along the axis of the object of protection. Each of the elastic elements, on which the protection object rests, is performed in the form of the dry friction spring damper. Damper consists of lower and upper support plates. Between the plates coaxially and concentric the external with right and internal with left angles of turns rise springs are installed. Lower support plate is base, on which springs lower flanges are rigidly attached. Between the top support plate and top flange of the internal spring the dry friction damper is installed. Damper consists of two contacting cylindrical discs. Bottom disc is rigidly linked with top flange of the internal spring. Top disc is rigidly linked with the top support disk. On facing each other surfaces of discs the concentric diametric grooves and inserted in them shoulders are made.

EFFECT: increased efficiency of vibration insulation is achieved by means of increasing the dissipative forces in the resonant operating modes.
