CAR DECLUTCHING BEARING FITTED BY SEALING UNIT AND SYSTEM TO INFLUENCE CAR CLUTCH Russian patent published in 2015 - IPC F16C33/80 F16D23/14 

FIELD: machine building.

SUBSTANCE: invention relates to a car declutching bearing comprising a rotating ring (1) and a fixed ring (2) set so that to form at least one annular cavity (8) in-between which is located on one of the rolling race (5) sides and is fitted by a sealing unit. The sealing unit is equipped by a reflector (9) attached to one of the rings (1, 2) and having two supports (9a, 9b) which pass in radial direction in the annular cavity (8) and are distanced from each other in axial direction and confine a ring seat (10), the said sealing unit also comprises an insert (11) installed at another ring (2, 1) and located in the ring seat (10) to form a U-shaped barrier (12) with its ends being limited between the respective inner side of one of the supports (9a, 9b) and the outer side of the said insert and its base being limited between the lower side of the ring seat (10) and the side of the free end of the said insert. The insert (11) is installed at one of the rings (1, 2) and is able of axial and/or radial displacement inside the ring seat (10).

EFFECT: development of such declutching bearing which provides for keeping reliable sealing of a rolling race and herewith for the limitation of the produced friction torque value.
