摘要

A double wishbone type suspension for suspending a carrier 10 for supporting a vehicle wheel 12 to be rotatable about an axis of rotation 12A is constructed by an upper arm 14 extending substantially in a lateral direction of a vehicle between its inboard end 18 pivotably connected with a vehicle body 20 and its outboard end 22 pivotably connected with a first portion 22 of the carrier, a lower arm 16 having at least two inboard ends 24, 26 spaced apart from one another in a longitudinal direction of the vehicle and pivotably connected with the vehicle body and an outboard end 30 pivotably connected with a second portion 20 of the carrier, a longitudinally expansible/contractible connection link 36 having one end 38 connected with a portion 38 of the lower arm substantially distant from the outboard end 30 thereof to be pivotable relative thereto about a substantially vertical axis 40 and another end 42 pivotably connected with a third portion 42 of the carrier substantially distant from the second portion 30 thereof, and a lateral link 60 having an inboard end 56 pivotably connected with the vehicle body and an outboard end 58 pivotably connected with either a portion 54 of the carrier substantially distant from the second portion 30 thereof in at least the longitudinal direction of the vehicle or the second end 42 of the connection link.
