FIELD: machine building. ^ SUBSTANCE: invention relates to plain bearing for suspension strut of four-wheel vehicle. Proposed bearing comprises upper collar (3) made in synthetic rubber and furnished with circular lower surface (2), lower collar (5) made in reinforced-synthetic rubber and applied on the said upper collar to revolve about its axis. The said lower collar has also circular upper surface (4) arranged opposite surface (2), and circular thrust part (6) made in synthetic rubber and arranged between surfaces (2) and (4). Lower collar (5) has surface (36) making a seat of cylindrical spring (61) and arranged on lower surface (25). Lower collar (5) comprises circular thrust section (12), upper cylindrical section (24), formed entirely on upper surface (23) of section (12). Surface (4) and lower cylindrical section (26) are formed on lower collar (5). The lower cylindrical section (26) is formed entirely on surface (25) of circular thrust section (22). Note here that surface (25) of section (22) arranged on radially outer surface (26) makes surface (36) of the seat of spring (61). Note also that sections (12), (24) and (26) comprise multiple tapered chambers. ^ EFFECT: reduced vehicle suspension weight and running gear cost. ^ 13 cl, 6 dwg |
