Filler ring for a vehicle wheel and tire assembly

摘要

A filler ring for a vehicle wheel and pneumatic tire assembly, in which the beads of the tire are mounted on the radially inner periphery of a drop-center wheel rim adjacent essentially radially inwardly extending rim flanges. The filler ring fills a space located between a tire bead and a wall of the drop-center. The filler ring is provided with a plurality of circumferentially extending hollow chambers that are disposed in two planes which are superimposed over one another in a radial direction and are separated from one another via a diagonal rib. Each of the planes of hollow chambers is provided with at least two hollow chambers that are successively arranged in an axial direction. The filler ring has a side wall that rests against a tire bead and extends perpendicular to the axis of rotation, and an oppositely disposed inclined wall that extends at approximately 80 DEG to the axis of rotation. The diagonal rib extends between a radially inner half of the side wall and a radially outer half of the inclined wall. To better prevent shifting of the filler ring radially inwardly, the diagonal rib forms an angle of less than 75 DEG -85 DEG with a radially inner half of the inclined wall.
