Abstract:
1. A front-wheel suspension system for the guidance and springing of the front wheel of wheeled vehicles having a single front wheel, said suspension system comprising: a frame supported on the vehicle wheels, the frame providing a first fixed front suspension point, a second fixed front suspension point and a fixed steering point; a swingable arm operatively connected at one end to the first fixed front suspension point and providing a variable second steering point at the other end of the arm; a second swingable arm operatively connected at one end to the second fixed suspension point and providing a variable third steering point at the other end of the arm, the second and third steering points defining the steering axis, a fork operatively combined with the frame and having at least one fork leg for connection to the front wheel of the vehicle, the fork having a longitudinal axis; a first fork joint operatively connecting the fork to the fixed steering point; a second fork joint spaced from the first fork joint along the longitudinal axis of the fork, the second fork joint operatively connecting the fork to the frame at the second steering point provided by the swingable arm; and a third fork joint spaced from and between the first and second fork joints and operatively connecting the fork to the third steering point provided by the second swingable arm, the fixed steering point providing only a steering function; the fork joints connected to the swingable arms being adjustably movable along the axis of the fork to thereby change the angle of the steering axis relative to the frame.
