Suspension system for steered wheel

摘要

A suspension system for a steered wheel includes a knuckle for steerably supporting the steered wheel about a king pin axis, and upper and lower arms pivotally supported on a vehicle body and connected at free ends thereof to upper and lower portions of the knuckle, respectively. This suspension system further includes a link mechanism which includes a first substantially vertically extending rod connected to the knuckle at a location more inward of the vehicle body than the king pin axis, and a second rod connected at one end to the first rod and at the other end to at least one of the vehicle body and the lower arm. A resilient device is connected to the link mechanism and adapted to exhibit a resilient force repulsive to the deformation of the link mechanism. Thus, even if the king pin offset is set at a small value, a restoring torque can be sufficiently insured in the steering device when steering through a large steering angle at a low speed.
