摘要： PURPOSE:To prevent stress or strain concentration, by providing a balanced shape for a reinforcing belt layer insertion section in consideration of the influence of the layer and another balanced shape for other sections extending to both side edges of the layer from the maximum width position of the longitudinal cross section shape of the inside surface of a tire. CONSTITUTION:The circumferential tension of the reinforcing belt layer insertion section of a tire which extends between both side edges B, B of a reinforcing belt layer and that of the other side sections of the tire are set in such a prescribed relation to each other that the circumferential tension of the reinforcing belt layer insertion section is higher than that of the other sections. At the side edge of the reinforcing belt layer, the shapes of the portions of the inside surface 5 of the tire are approximated to each other on the basis of film balance so that the shapes of the portions are made continuous to each other. The tension of the reinforcing belt layer insertion section differs from that of the other outer side sections under the preconditions. In the approximation, the preconditions are determined from the modulus of elasticity of the belt and structure of the reinforcing belt insertion layer and the modulus of elasticity of the elastic material of the other side sections to provide the inside surface 5 with a shape of curvatures of radius according to separate prescribed formulae (not mentioned here).

摘要： PURPOSE:To get a low-cost and reliable internal pressure controller of tires used for an electric car, by using a noncontact type signal transmission system from the rotary body to the chassis which introduces the internal pressure of tires to a prssure indicator at the driver seat through a rubber hose. CONSTITUTION:The internal pressure of a tire 10 is introduced to a pressure indicator 11 through a rubber hose 12 connected with a tire hub 35. As the internal pressure drops to 8.5kg/cm and a pressure switch is turned off, the current ceases to flow through a resonant coil assembly 14. This eliminates resonance even when both coil assemblies 14, 15 draw near to each other and output of the oscillating coil assembly 15 is not reduced. The detection of a differential signal of output from the oscillating coil assembly 15 leads to the detection of any reduction in the tire pressure through effective control. Being processed by an electric circuit, the differential signal is fed in a controller 16 through a shielded wire 25 to generate an alarm signal and indicate a pressure drop by an indicator 17.
