Non-pneumatic type tire

Abstract

Abstract PURPOSE:To improve durability and driving stability in respect of the title tire which has an inner and an outer peripheral wheel joined by web and inclined ribs by forming two groups of ribs installed on the same side face of the web so that one group inclined at an angle on one side of the radial plane and the other group inclined at an angle are inter mingled with each other. CONSTITUTION:An outer peripheral wheel 2 and an inner peripheral wheel 3, which are in a concentric shape, are joined by one ring-shaped web 4, both sides of which are, in addition, provided integrally with ribs 5 joined to the inner and the outer peripheral wheel. Also, the arrangement is made in such a manner that these ribs 5 are inclined to a radial face F against which ribs 5a and ribs 5b are inclined in one direction at an angle alpha and in the other direction at an angle alpha respectively to be mixed one after another. In this way, the inclined ribs are distributed in a peripheral direction, thereby permitting a local deformation of the only part of a tire which is at rotation as well as deformation and load duty as a pneumatic tire. Durability and driving stability can thus be improved.
