PURPOSE:To improve the extent of steering stability at time of running at high speed by supporting a body width central aprt of a rear axle housing pivotally on a top part of a V-shaped upper radius rod, and suspending each spot at both ends in the body width direction on an undercarriage frame by means of a longitudinal pair of columnar rubber members. CONSTITUTION:A top part of a V-shaped upper radius rod 34 being installed along a center line in the longitudinal direction of a car body is pivotally attached to the upper side of a differential casing 38 installed in the central part of a rear axle housing 16 via a ball joint unit 36, and both leg ends of the housing 16 is pivotally attached to a side rail 12 of an undercarriage frame 10. The rear axle housing 16 is steered and rotated by a hydraulic cylinder unit 56 via a lower radius rod 46. In addition, a longitudinal pair of columnar rubber members 24 is interposed between the rear axle housing 16 and the undercarriage frame 10 so as to form a side form into a V-shaped form. These columuar rubber members 24 are composed of plural rubber pads 32 baked and stuck fast each to plural steel sheets set up in the mid part. |
