US 4,505,314 A · Wheel with tire bead locking ring

Abstract

A wheel for mounting tubeless tires in which the bead of the tire is sealed and clamped on one or both sides of the wheel. The bead is sealed and clamped by a bead locking ring having a peripheral lip on an axially parallel surface of revolution, terminating in an annulus which mates with a similar surface of revolution formed on one or both ends of the wheel having a matching annulus to which the ring is securely bolted. The annulus on the wheel is provided with a plurality of blind threaded inserts for receiving bolts which pass through the ring, securely clamping the bead between a peripheral lip on the wheel and the lip on the bead locking ring. The locking ring is formed so that the mutual surfaces of revolution on the locking ring and the wheel respectively provide lightweight, reinforced stiffening of the locking ring (i.e. in-plane strength), preventing bending and warping when bolted to the wheel.

Dependent claims

A wheel for mounting a tubeless tire having two sidewalls and a pair of beads possessing the property of limited deformability to conform to a rigid surface that makes a sealing contact with them, said wheel comprising:

a hub having a central axis;
bead locking ring means mounted on at least one end of said hub means, said bead locking ring means having a flange with a peripheral lip, a radial annulus and a surface of revolution parallel to said axis constructed to receive and extend beyond said bead, said surface of revolution constructed to seal said bead when said bead abuts said lip;
a flange on at least one end of said hub having a peripheral lip and a surface of revolution parallel to said axis terminating in a radial annulus substantially identical to the surface of revolution a radial annulus on said bead locking ring means to that said bead locking ring means and said flange on said hub mate in a close tolerance fit with and reinforce the surface of revolution and radial annulus on said bead locking ring means;
mounting means mounting said bead locking ring means with said bead clamped between the peripheral lips on said flange and said bead locking ring means whereby said tire is sealingly mounted and securely clamped to said wheel.
