Abstract

PURPOSE:To reduce the number of component parts used in a strut type vehicle suspension device, and to make the suspension device lightweight, by attaching a lower arm pivotally to the lower section of a damper, and by coupling a steering nuckle to a damper base lower section in the vicinity of the damper lower section, rotatably about the axis of the damper. CONSTITUTION:The base section 12 of a steering nuckle 21 is coupled rotatably to a shaft section 41c projecting from the lower end of strut cylinder of a damper 11 through bushings 45, 45, and further, a lower arm 13 is attached to a bracket 44 which is in turn attached to the lower end of the shaft section 41c by means of a nut 43. Further, a tie-rod 52 is coupled to a steering nuckle 12 by means of a ball joint which is not shown. The lower arm 13 is coupled to a vehicle body frame by means of a coupler 78. With this arrangement, no ball joint is required in the upper section of the damper 11, resulting in simplifying the structures of coupling sections, thereby it is possible to reduce the number of component parts used in the suspension unit and to make the latter lightweight.
