摘要:
A two-piece tire assembly has a removable tread belt (12) for installing about the circumference of a tire carcass (14). The tread belt has a pair of lateral ends each axially extending beyond the inflated unloaded carcass (14) at the circumferential surface by a distance of at least 4% of the width as measured at the tread belt (12) and carcass (14) interface. The carcass (14) has an abrasion resistant rubber layer (82) at the tread belt interface. The tread belt (12) also has the abrasion resistance tread compound (82) at the carcass (14) interface.
摘要:
A tyre system for motorcycles which comprises a pneumatic tyre (2) having a cavity, an annular tyre core (6) made of an elastic closed-cell material disposed in the cavity and provided on the radially inside with a groove, and a pressure bag (5) inserted in the groove, wherein in the free state of the tyre core when it is not disposed in the cavity, the cross sectional area Sa is in the range of from 3.1 to 4.8 times the cross sectional area Sb of the groove; and the total Sa+Sb of the cross sectional area Sa of the tyre core and the cross sectional area Sb of the groove is in the range of from 1.0 to 1.3 times the cross sectional area Sc of the cavity.
摘要:
Disclosed is a self-supporting tyre for wheels for bicycles, motorcycles and the like comprising an outer surface layer (5), which establishes contact with the ground (8) and an inner supporting layer (6) realized by a flexible polyurethane elastomer with a cellular structure, which at least partially occupies the internal volume of the tyre (1) and supports the outer surface layer, also comprising a flexible membrane (9) substantially having the shape of the outer layer (5) and radially compressing the inner supporting layer (6).
摘要:
A pneumatic tire that does not require mending a puncture outside the car and that prevents leakage of air without entailing an weight increase or the aggravation of riding comfort as found in a conventional puncture-less tire; and a method of producing the same. This pneumatic tire has a rubber-like thin film applied to the inner surface thereof, which film has a breaking extension of not less than 900% and a tensile strength of not less than 15 MPa. The rubber-like thin film is in the form of a dried thin film of latex.

摘要:
A tyre (3) for vehicles which does not require pressurisation by means of a pressurised fluid has a tread (16), two sidewalls (15), and two beads (8) which are attached to a wheel rim (2) made of elastomer material, and is provided with at least one tubular reinforcement body (18) which is associated with the tread; each of the sidewalls having a respective homogeneous resilient annular membrane (24), a straight generatrix of which forms an angle (A) other than 90° with the axis (13) of the tyre (3); the membranes (24) being stretched radially between the tread (16) and the beads (8) such as to be pre-tensioned in the absence of external loads acting on the tyre (3).
