Title:
THRUST BEARING FOR VEHICLES
Document Type and Number:
WIPO Patent Application WO/2016/163445
Kind Code:
A1
Abstract:
Provided is a thrust bearing for vehicles, which is configured so that: the direct contact between an annular recess and an annular protrusion, which form a labyrinth structure between an upper case and a lower case, is avoided to prevent torque from increasing and noise from occurring; and lubricating oil present in the thrust bearing is prevented from leaking. A thrust bearing (100) for vehicles is configured so that a labyrinth structure (RB) comprising an annular recess (121b) and an annular protrusion (111ba), which are formed concentric with an upper case (110) and a lower case (120), is formed on the case outer peripheral side or the case inner peripheral side of the portion where the upper case (110) and the lower case (120) are in direct or indirect contact with each other, a labyrinth spacer member (140) for preventing the direct contact between the annular recess (121b) and the annular protrusion (111ba) is disposed between the annular recess (121b) and the annular protrusion (111ba), and the labyrinth structure (RB) reduces sliding resistance during relative pivoting to a level lower than that in the case where the annular recess (121b) and the annular protrusion (111ba) are in direct contact with each other.
