Patent ID: 8091596

Claim:
A non-pneumatic wheel assembly which has (i) an outer rim assembly ( 26 , 26 A); (ii) an inner vehicle hub connection member ( 11 , 11 A); (iii) a compartment ( 9 ) located between the outer rim assembly ( 26 , 26 A) and the inner hub connection member ( 11 , 11 A); (iv) at least one pair of arrays of spring elements ( 21 ); (v) at least one other array of spring elements ( 22 , 22 A); and (vi) at least some of the spring elements ( 21 , 22 ) of both the at least one pair of arrays of spring elements and the at least one other array of spring elements attached to the outer rim assembly ( 26 ) and to the inner vehicle hub connection member ( 11 ), wherein: the spring elements ( 21 , 22 ) of both the at least one pair of arrays of spring elements and the at least one other array of spring elements are arcuate and the spring elements ( 21 ) of the at least one pair of arrays of spring elements are arranged in an opposing or counteracting orientation being convexly curved in a first circumferential direction of the wheel assembly, to the spring elements of the at least one other array ( 22 , 22 A) being convexly curved in a second circumferential direction of the wheel assembly opposite to the first circumferential direction; and each of the respective arrays of the at least one pair of arrays ( 21 ) of spring elements and the at least one other array ( 22 , 22 A) of spring elements is located in a plane that is different from the planes in which the other arrays are located.
