摘要： In a process for manufacturing, moulding and curing tires for vehicle wheels without a vulcanization bladder, many drawbacks can result from a direct contact between the green tire and the fluid under pressure admitted in order to create the necessary pressing of the elastomer material against the vulcanization mould walls. In accordance with the present invention, said drawbacks are avoided by including in the tire manufacturing process a step of treating the inner surface of the green tire in order to prevent the permeation of the fluid under pressure into the inside of the tire structure. Said treatment can be carried out by associating at least one layer of prevulcanized elastomer material with the inner surface of the green tire.

摘要： A method for determining the force at the hub of a wheel of a vehicle while traveling. The wheel includes a rim and at least one deformation sensor directly associated with the rim in at least one predetermined position and arranged according to at least one predetermined orientation. The method includes the steps of detecting at least one deformation component of the rim during travel through the at least one deformation sensor; applying to the at least one deformation component, during travel, a correlation parameter characteristic of the rim, between the force at the hub and the relative deformation of the rim to determine at least one force component at the hub correlated with the at least one deformation component of the rim. The determining of the correlation parameter preferably takes place through experimental tests that include the steps of providing a sample wheel having a rim substantially the same as that of the wheel and determining at least one correlation coefficient between at least one force component acting upon the sample wheel at the hub along at least one predetermined direction and at least one respective deformation component of the rim of the wheel.
