Abstract
A rotatable wheel having a rotary shock absorber coupled on an axle and between a disc brake rotor and the rotatable wheel, for providing enhanced suspension. The rotary shock absorber consists of an air-tight hollow disc structure filled with lubricant, the disc structure further having a central circular opening, a sealing plate coupled to and sealing the central circular opening on one side, a sealing boot portion coupled and sealing the central circular opening on the other side, and a circular hub portion nesting inside the hollow disc structure. The hub portion further has six circular through holes, one or more identical helical springs nested firmly inside each of the six circular through holes, and six lug bolts each having two threaded ends and a smooth body. Each of the six lug bolts is further coupled rigidly and perpendicularly at the center of each of the two corresponding helical springs and secured on both ends at each side of the hollow disc structure.
