ABSORBING APPARATUS Russian patent published in 2020 - IPC B61G9/10 B61G9/18 

FIELD: machine building.

SUBSTANCE: in the steel housing of the absorbing apparatus, made in the form of a rectangular barrel, symmetrically to its inner walls the steel pressure wedge, two friction wedges with the support plate, by two friction fixed, with metal-ceramic pads of material with friction coefficient of sliding on steel of not less than 0.4, and movable plates, as well as spring reciprocating device of two parallel (external and internal) cylindrical helical compression springs with total rigidity of not more than 920 kN/m, located along with the support plate and friction wedges between the housing bottom and the pressure cone and a bolt tightened along the longitudinal axis, which is inserted through the base holes available in the housing bottom, the support plate and pressure wedge.

EFFECT: guaranteed compliance of power consumption of spring-friction absorbing device with level not lower than T1 class.
