FRICTION ABSORBING DEVICE Russian patent published in 2018 - IPC B61G11/14 

FIELD: transportation.

SUBSTANCE: invention relates to the railway transport, in particular to the automatic couplings friction absorbing devices. Friction absorbing device comprises housing, and friction spacer unit. Housing comprises bottom and side wall together defining the open at one end housing inner space. Friction spacer unit consists of pressure cone, friction wedges, stationary friction plates, movable friction plates, support plate resting against the retaining-return device. Retaining-return device rests against the housing bottom. Facing the device housing movable plate surface is made with the vertical plane deviation. At that, the cross-section surface points removal from the vertical plane decreases from the middle to the edges with the ratio H fulfillment, which must be at least 0.005 L, where H is deviation from the vertical plane, L is the plate width.

EFFECT: enabling increase in the absorbing device operation efficiency and reliability.
