Abstract
Abstract An emergency supporting ring for vehicle wheels with pneumatic tires, which is arranged within the hollow chamber of the tire and is equipped with blocks of rubber material which blocks are uniformly distributed over the circumference of said emergency supporting ring, the total of the distance between each two adjacent blocks measured along the outer circumferential circle of the ring being greater than the difference between the circumferential circle of said ring and the inner tire circumference while the difference in the circumferential speed of said outer circumferential surface of said ring and the outer circumferential surface of the tire is compensated for by a shear deformation of the blocks, the spacing between two adjacent blocks being such that at the ground contacting area of the tire when the wheel is under the rated load of the tire is greater than the deformation stroke of the blocks during their shear deformation.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
238 words
A vehicle wheel which includes: a rim, a pneumatic tire mounted on said rim, and an emergency supporting ring member arranged radially inwardly of and in spaced relationship to said pneumatic tire and supported by said rim, said ring member including a plurality of block means forming the outer circumferential portion of said ring member and defining recesses therebetween of approximately identical magnitude so as to space radially outer portions of said block means from each other, the total of the width of all of said recesses measured along the outer circumferential circle of said emergency ring member being greater than the difference between the inner circumferential circle of the tire in inflated condition and the outer circumferential circle of said emergency ring member, said block means being adapted to undergo a shear deformation for compensating for the difference in the circumferential speed of said ring member and said tire in deflated condition of the latter, the distance between adjacent block means in inflated condition of the tire being such that in deflated condition of the tire and with the rated wheel load acting upon said ring member the distance between adjacent block means in the circumferential direction of said ring member and within the ground contacting region of the tire being greater than the deformation stroke of the respective block means during their shear deformation, the outer circumferential surface of said block means being provided with blocks.
Claim 2
Dependent Claim

A vehicle wheel which includes: a rim, a pneumatic tire mounted on said rim, and an emergency supporting ring member arranged radially inwardly of and in spaced relationship to said pneumatic tire and supported by said rim, said ring member including a plurality of block means forming the outer circumferential portion of said ring member and defining recesses therebetween of approximately identical magnitude so as to space radially outer portions of said block means from each other, the total of the width of all of said recesses measured along the outer circumferential circle of said emergency ring member being greater than the difference between the inner circumferential circle of the tire in inflated condition and the outer circumferential circle of said emergency ring member, said block means being adapted to undergo a shear deformation for compensating for the difference in the circumferential speed of said ring member and said tire in deflated condition of the latter, the distance between adjacent block means in inflated condition of the tire being such that in deflated condition of the tire and with the rated wheel load acting upon said ring member the distance between adjacent block means in the circumferential direction of said ring member and within the ground contacting region of the tire being greater than the deformation stroke of the respective block means during their shear deformation, the outer circumferential surface of said block means being provided with blocks.
Claim 3
Dependent Claim
39 words
A vehicle wheel according to claim 1, in which the ratio of the freely deformable height of the block means to the height of said blocks is within the range of from 5 : 1 to 8 : 1.
Claim 4
Dependent Claim
271 words
A vehicle tire which includes: a rim, a pneumatic tire mounted on said rim, and an emergency supporting ring member arranged radially inwardly of and in spaced relationship to said pneumatic tire and supported by said rim, said ring member including a plurality of block means forming the outer circumferential portion of said ring member and defining recesses therebetween of approximately identical magnitude so as to space redailly outer portions of said block means from each other, the total of the width of all of said recesses measured along the outer circumferential circle of said emergency ring member being greater than the difference between the inner circumferential circle of the tire in inflated condition and the outer circumferential circle of said emergency ring member, said block means being adapted to undergo a shear deformation for compensating for the difference in the circumferential speed Of said ring member and said tire in the deflated condition of the latter, the distance between adjacent block means in inflated condition of the tire being such that in deflated condition of the tire and with the rated wheel load acting upon said ring member the distance between adjacent block means in the circumferential direction of said ring member and within the ground contacting region of the tire being greater than the deformation stroke of the respective block means during their shear deformation, the circumferential surface of said block means being rounded in the circumferential direction of said ring member, and the ratio of the rounding radius to the outer circumferential diameter of said ring member being within the range of from 0.1 to 0.13 : 1.
Claim 5
