Abstract

A front wheel suspension in which a pin connects an upper link to a push rod. The push rod is also swingably connected to a front wheel supporting arm. The push rod is arranged such that the displacement gradient of the pin maintains a constant sign throughout a suspension stroke of the front wheel. This motion is accomplished by ensuring that an angle between an axis of a front fork and an axis connecting pivot points on the front wheel supporting arm is maintained at less than 90° throughout the suspension stroke.
