Patent ID: 6893037

Claim:
A telescopic front suspension for use with vehicles having a single front wheel comprising a steering tube adapted to be mounted in a head tube of a frame of the vehicle and connected to stem and handle bar above the head tube and to a fork crown below the head tube for steering the vehicle; a pair of stanchion tubes spaced apart and extending downwardly in parallel with each other having an elongated shape with upper ends attached to the fork crown and lower ends which slide axially and telescopically inside of a corresponding pair of slider tubes having an elongated hollow shape with upper ends which receive the stanchion tubes therein and lower ends mounted on respective sides of an axle for the front wheel, wherein the outer shape of the stanchion tubes and inner shape of the slider tubes have matching cross-sectional shapes that are non-round, smooth curves so as to allow them to freely telescope relative to each other while preventing rotation between the parts, resulting in more precise steering control for the rider, and further comprising an external bushing mounted on each one of the upper ends of the slider tubes having an inner shape matching the outer shape of the stanchion tubes, and an internal bushing mounted to each of the lower ends of the stanchion tubes having an outer shape matching the inner shape of the slider tubes, wherein the two-bushing arrangement allows the distance between the upper bushing and lower bushing to increase as the stanchion tube is telescopically displaced inside the slider tube, wherein the external bushing has a bushing carrier that is mounted over the upper end of the slider tube and wherein the bushing carriers mounted on the upper ends of the two slider tubes have bosses provided with mounting holes for mounting a fork bridge to the slider assemblies.
