Patent attributes
A strut type suspension device which contains a strut (7) whose upper end is supported on an insulator (3) mounted on a vehicle body (1), an upper seat (5) arranged on the lower face of the vehicle body with a bearing (4) interposed therebetween, a lower seat (8) fixed to said strut, and a compression coil spring (6) arranged around the strut between the upper seat and the lower seat, and which supports the vehicle body by means of the strut and is capable of turning about a kingpin axis, wherein the bearing is arranged in an inclined fashion such that the kingpin axis and the bearing central axis roughly coincide, so that no rotational moment is generated about the kingpin axis. Due to the above arrangement of the strut-type suspension device, the strain energy of the spring is unchanged irrespective of the rotation angle about the kingpin axis, even if the amount of the eccentricity varies, and thereby straight traveling stability is improved.
