TH22994A - Sealing loop between the rubber edge of the car tire - Google Patents

Abstract

An annular piece (3) is placed between two rims (12) of the tire (P) that are mounted on a flat base wheel (J) to enable Use the tires on the wheels that As mentioned above without having to use inner tubes Ring-shaped parts to insure a tight fit of the assembly have a meridian section around the perimeter. And especially There are two side (30) sides in such a way that the compression (s) between the ring and the bead is zero or negative at The base of the loop will be slightly increased over the radial h1, and then greatly increased. On the radial distance h2 that are close to each other in the radial distance from the first

Claims (9)

1. Sealing loop for mounting onto the base of the wheel between the rim of the car tire, which rate The inner cavity portion H / S at most 0.8, where H is the height of the inner cavity of the tire and S is the maximum axial width of the inner cavity of the tire. In the state has not been Installed to be assembled as well. Scoped meridian section The radial parent has the same radius RA as the radius R1 of the base of the wheel of the wheel for mounting. And the axial width LAO.Values between 0.8 and 1 times the axial distance LBO between the inner ends along the The axis of the inner rim of the tire to be mounted on the wheel, the radial outer master line with a longer radius than the radius RA is the amount hc, which is between 0.05 R1 and 0.40 R1 and two sides with exactly the same profile. Where the LA-LB cross-section of the loop on the inner wall of the rubber bead If negative or zero at the level of the inner parent line, it is a slight increase over the radial distance h1 which is at least 0.05 R1 and then increases. At most on the radial distance h2, which at most is 0.4 R1, and then is almost Constant on the radial distance h3, which is at least 0.02 R3, where the sum of the h1, h2 and h3 distances is equal to the height hB of the sides of the loop, the difference hB-hC at most is 0.05 RJ and The stages LA and LB will be the width of the hoop. And distance between the rubber edges, respectively It is measured in the line across the parent line G at the variable radial distance h from the parent line of the meridian section with radius RA. 2.
