초록 ▼

A resilient suspension system for the front wheel of a bicycle or the like which turns bump energy into viscous heat loss without absorbing the pedaling energy of the rider. The suspension system includes two telescoping tubes having fluid therein and a fluid valve that meters the fluid flowing between the two tubes on the compression and expansion of the tubes. The invention also employs certain design features so as to retain the structural rigidity of the front fork assembly while remaining light in weight and utilizing a majority of the standard bicycle wheel, brake and steering components.

대표청구항 ▼

A bicycle wheel suspension system for the front fork of a bicycle, comprising: two suspension assemblies, one disposed within each leg of the front fork of a bicycle; each said suspension assembly including an upper telescoping tube and a lower telescoping tube, said telescoping tubes being configured such that one said telescoping tube is axially, slidably engaged within the other of said telescoping tubes; each said telescoping tube having a sealing plate disposed therein, said sealing plates being disposed to form a fluid-holding chamber, a respective portion of said chamber being disposed within each of said tubes; a fluid being disposed within said chamber; a fluid valve means being disposed within said chamber and functioning to meter the flow of said fluid from one of said tubes to the other of said tubes upon the axial, sliding movement of said tubes relative to each other; wherein said fluid in said chamber is sufficient in volume to fill said lower tube portion of said chamber upon the full slidable extension of said tubes, and to also fill a portion of said upper tube; said upper tube portion of said chamber having sufficient volume to hold all of said fluid upon full axial sliding compression of said tubes with an air space remaining in said upper tube portion of said chamber; wherein a first bushing is fixedly engaged to said upper tube and makes a fluid-tight sliding seal with said lower tube, and a second bushing is fixedly engaged to said lower tube and makes a fluid-tight sliding seal with said upper tube; and wherein a wall of one of said tubes has a port to permit the transfer of said fluid through said port and into a space between said bushings during axial sliding compressive movement of the tube tubes and the bushing on the other of said tubes is displaceable into a position blocking said port near the end of axially sliding extension of said tubes as a means for locking said tubes and preventing contact between said bushings.
