SUBSTANCE: absorbing assembly friction unit comprises housing (200) with open front end and closed rear end that form the ledge to be received in the absorbing assembly recess. The housing first end has the first rear part, second rear part (206), the latter being closed by end wall (208), and pairs of rear extending elements (204) arranged between the first and second rear parts and a pair of rear limiters adjoining the aforesaid pair. The coupling pusher incorporates first part (232) with inner surface in contact with the pair of horizontally arranged moving plates and a central wedge of the absorbing assembly friction unit. The said inner surface faces the outer surface in contact with the working surface with each said front limiters. The said pusher comprises also a pair of opposite ends arranged between the inner and outer surfaces and furnished with multiple angular holes (240). The coupling pusher comprises additionally the second part arranged between the outer surface and coupling arm. Note that the pusher is fitted to axially move within the said pair of opposite holes (220) and the pair of opposite second holes of the pusher second pen end.
EFFECT: increased shock-absorbing capacity.
