<p>The system consists of a supporting arm (8) for the wheel axle (6), a steering column (3), a shock absorber, and a lever, cam or slider mechanism which allows the angle between the steering column and supporting arm to be varied. The mechanism comprises at least one pivot (15) which can move both relative to the supporting arm and steering column when the shock absorber is compressed. The pivot (15) is moved by a lever (12) which is pivoted to the supporting arm and connected to a rod (9), ensuring that the wheel axle moves up and down in a near vertical trajectory in the shape of a flattened S-curve.</p> |
