PLAIN THRUST BEARING AND MOUNTING STRUCTURE OF POST-TYPE SUSPENSION WITH PLAIN THRUST BEARING

摘要

FIELD: machine building.;SUBSTANCE: invention relates to the plain thrust bearings from synthetic resin, namely, to the plain thrust bearings used in post-type suspensions (McPherson suspension) for four-wheeled vehicles, and also to the mounting design of the post-type suspension with the plain thrust bearings. The plain thrust bearing (1) comprises a lower housing (2) from synthetic resin, upper housing (3) from synthetic resin laying on the lower housing (2), and an insert (4) from synthetic resin placed between the housings (2, 3). The upper housing (3) is laid on the lower housing (2) in such a manner that the tubular outer surface (34) of an internal tubular suspended part (29) of the circular bearing parts (25) is located opposite to the tubular internal surface of the larger diameter of the circular bearing part (11) of the housing (2) with a clearance between them. Meanwhile the circular lower end surface of the part (29) is located opposite to the surface with a circular shank shoulder of the part (11) with the clearance between them. The cylindrical internal surface (31) of the external tubular suspended part (32), with the walls wider, than ones of the part (29) in a radial direction, forms a sliding contact with the cylindrical outer surface (9) of the part (11). The internal tubular vertical part (38) of the wall is located in the circular part (18) with the recess. The circular hook part (44) is elastically seats in a circular gripping protruding part (20), as a result of which between the elastically seated part and the smoothly contacting part of the surface (9) an sealing part of the labyrinth type is formed with reference to the cylindrical internal surface (31) due to that the part (38) of the wall is located in the part (18), and the tubular protruding part (19) and the part (20) are located in the circular part (42) with the recess.;EFFECT: creation of plain thrust bearing with a possibility of resolving the problem with the space for mounting.;2 cl, 8 dwg
