PURPOSE:To improve the steerability of a vehicle when a great lateral force is applied to the wheel thereof in a suspension which compensates the under steering characteristics intensified at said application time by devising the spring characteristics of two wheel supporting bushes which are arranged in the longitudinal direction of the vehicle. CONSTITUTION:There is provided a means of so supporting left and right rear wheels 3 via a pair of right and left wheel supporting members 2 (the accompanying words are omitted hereinafter) as that the right and left rear wheels 3 are capable of being moved up and down with respect to the sub frame 1 of a vehicle. In said means the spring characteristics of each of the bushes 12 and 14 is so devised as that when supporting shafts 11 and 13 projected from both the front and rear end parts of a connecting link 6 of each of the wheel supporting members 2 are connected to the external end parts of the front and rear lateral links 4 and 5 via bushes 12 and 14, respectively. The ratio of the deflection amount of the front bush 12 with respect to that of the rear bush 14 in case of a low lateral force is high in comparison with the ratio gained in case of a great lateral force. The internal thickness of the internal sleeve 21 inside the bush 12 is greater than that of the internal sleeve inside the bush 14 and two grooves 24 are made on the external periphery of the rubber member 23 of the bush 12. |
