FRICTION SHOCK ABSORBER Russian patent published in 2016 - IPC B61F5/12 F16F7/08 

FIELD: machine building.

SUBSTANCE: invention provides friction damper containing pressure wedge resting on pressure spring and spacer ring via friction wedges interacting with friction barrel, distance ring made from dielectric material, a current source connected with pressure wedge and friction barrel, current regulator, first adder, first setting unit, dual integrator and rectifier. On current control is transmitted a signal with element “OR” to inputs of which receives signals from outputs of first and second adders, first adder signal is supplied from first setting unit and signal from sensor vertical acceleration of bolster, twice integrated first and second integrators, forming double integrator, rectified rectifier and faired smoothing filter, and at second adder signal is supplied from second setting unit and signal from bolster vertical acceleration sensor once integrated first integrator, taken in magnitude of module isolation unit signal.

EFFECT: higher smooth crew, reducing its impact on path.
