Embodiment Construction

[0047] The thrust sliding bearing of the present invention comprises: an annular upper shell, which is inserted into the upper front end of the piston rod used in the shock absorber of the strut type suspension; an annular lower shell, which surrounds the axis of the piston rod, Rotatably overlapped with respect to the upper case; a ring-shaped synthetic resin sliding bearing piece is sandwiched in the annular space formed between the upper case and the lower case and receives the thrust load of the piston rod; and a ring-shaped metal plate , fixed to the piston rod, sandwiched between the upper shell and the synthetic resin sliding bearing piece, wherein the upper shell is integrally composed of an annular upper shell base and an upper shell cylindrical portion, and the annular upper shell The base portion forms an annular lower surface, the upper shell cylindrical portion hangs from the annular lower surface of the upper shell base and fits into the lower shell, and a synthet...

Abstract

The present invention provides a thrust sliding bearing in which the number of parts is reduced, the burden of assembling or the burden of parts management is reduced, and the abnormal wear of the surface of the synthetic resin sliding bearing piece on the side of the annular metal plate is prevented. In the thrust sliding bearing (100), the upper shell (110) is at least integrally formed by an annular upper shell base (111) and an upper shell cylindrical portion (112), and the annular upper shell base (111 ) forms an annular lower surface (111a), and the upper shell cylindrical portion (112) hangs down from the annular lower surface (111a) of the upper shell base (111) and is opposite to the lower shell (120). Fitting, synthetic resin sliding bearing piece (130) is fixed to the inner side of upper casing cylindrical part (112).

Description

technical field [0001] The present invention relates to a thrust sliding bearing which has an upper shell and a lower shell and relatively slides and rotates, and more particularly relates to a thrust sliding bearing which can be assembled to a strut type suspension (Macpherson type) of a four-wheeled vehicle. Background technique [0002] In general, a strut type suspension for a four-wheeled vehicle has a structure in which a damper spring is combined with a strut assembly in which a hydraulic damper is built in an outer cylinder integrally formed with a main shaft. [0003] Regarding the strut type suspension, there are types in which the piston rod of the strut assembly rotates when the strut assembly is rotated together with the damper spring by the steering operation, and a type in which the piston rod does not rotate, but both of them have the following cases , That is: in order to make the strut assembly rotate smoothly, between the mounting mechanism of the strut as...
