Patent ID: 6843536

Claim:
A brakable wheel hub device adapted to be rotatably mounted on an axle about an axis in an axial direction, said brakable wheel hub device comprising: a wheel hub shell having inner and outer surrounding shell surfaces which are disposed opposite to each other in radial directions relative to the axis, and an annular right end surface which extends radially to connect said inner surrounding shell surface with said outer surrounding shell surface, said inner surrounding shell surface being adapted to spacedly surround the axle, and including right and left inner surface segments proximate to and distal from said right end surface, respectively; a brake disk which is adapted to be rotatable relative to the axle about the axis, and which is outboard to and which confronts said right end surface; a right spoke mounting member including a securing wail portion disposed to surround the axis and mounted inboard to said brake disk, said securing wall portion extending in radial directions relative to the axis to terminate at a periphery, and a surrounding wall portion extending from said periphery of said securing wall portion leftwardly and in the axial direction so as to be adapted to engage wheel spokes, and having an inner tubular surface which confronts said outer surrounding shell surface radially to confine a surrounding space therebetween; a tightening member disposed to bring said securing wall portion to abut against said brake disk; and a force transmitting member received in said surrounding space, and having inner and outer frictional engaging surfaces which are disposed opposite to each other radially, and which frictionally and respectively engage said outer surrounding shell surface and said inner tubular surface such that said right spoke mounting member is synchronously rotated with said wheel hub shell.
