Abstract
The present invention is directed to a vehicle wheel suspension which includes a strut mounted at the upper end thereof on a vehicle body for supporting a wheel, a lower seat fixed to the strut, an upper seat mounted on the vehicle body, and a helical compression spring mounted between the lower seat and the upper seat, with the strut enclosed in the spring. The spring has a coil axis substantially curved at a predetermined radius of curvature in an unloaded state of the spring. The lower seat is tilted at a first predetermined angle in such a direction that the longitudinal length of the spring at the outside of the vehicle body is shortened when the spring is mounted between the upper seat and the lower seat, and/or the upper seat is tilted at a second predetermined angle in such a direction that the longitudinal length of the spring at the inside of the vehicle body is shortened when the spring is mounted between the upper seat and the lower seat. And, the spring is held in such a state that the coil axis of the spring is curved to extend outside of the vehicle body.
