Double link type suspension system.

摘要

A double link type suspension system (10) having an extension member (32) for movably connecting the upper section of a knuckle (12b) and an upper control arm (40) movably connected to the side of a vehicle body (31). A rotatable joint mechanism (34) is provided between the knuckle upper section (12b) and the extension member (32) and includes a cylindrical member (34a) fixed to the extension member (32). The axis of the cylindrical member is aligned with an axis line (36) passing through a joint (26) between the lower section of the knuckle (12a) and a lower control arm (28) movably connected to the vehicle body side (31). A pivot shaft (34f) fixed to the knuckle upper section (12b) is disposed inside the cylindrical member (34a) and rotatably supported through two deep groove ball bearings (34b, 34c) disposed between the pivot shaft (34f) and the cylindrical member (34a), thereby reducing jointing error between the knuckle (12) and the extension member (32) thus reducing camber angle error.
