摘要： A tyre for a wheel of a vehicle comprises a toroidal carcass provided with axially opposite sidewalls and beads for anchoring the tyre to a rim of the wheel, a tread band located crownwise on the carcass, comprising a surface with a plurality of hollows and grooves defining a raised tread pattern, and a belt structure interposed between the carcass and the tread band, axially extending between the sidewalls. The tread band comprises at least first and second circumferential axially-contiguous portions arranged to contact a road surface. The first portion is formed of a first composition comprising a reinforcing filler having at least 40%-by-weight carbon black and at least some white filler, the second portion is formed of a second composition comprising a reinforcing filler having at least 20%-by-weight white filler, and the first composition is different from the second composition. A difference of compositions between the at least first and second portions achieves a tyre operating temperature lower than a reference temperature.

摘要： A tire for a two-wheeled vehicle includes a carcass of toric form having a high transverse curvature, a tread band, and a circumferentially-inextensible belt structure. The belt structure is interposed between the carcass and the tread band, and includes reinforcing elements. Relative to an equatorial plane of the tire, the reinforcing elements may be randomly oriented, substantially oriented in an axial direction, or substantially oriented in an inclined direction. The belt structure further includes a radially-external layer provided with a plurality of cord coils disposed at a substantially-zero angle relative to the equatorial plane of the tire. The cord coils are positioned in axial side-by-side relationship and extend from one axial extremity of the belt structure to an opposite axial extremity. A density of the cord coils grows from the equatorial plane of the tire to the axial extremities of the belt structure.

摘要： A vulcanizable rubber composition for treads of vehicle tires, comprises: a) a cross-linkable unsaturated chain polymeric base including 1 to 40 phr of at least an unsaturated chain modified polymer including polar groups, b) 15 to 100 phr of a silica-based reinforcing filler including superficial hydroxyl groups, c) 0.5 to 5 parts by weight per each 100 parts by weight of said silica-based reinforcing filler of at least a sulfur-containing stabilizing agent of the vulcanization network, d) an effective amount of at least one vulcanizing agent. Advantageously, said rubber composition allows to obtain a tread with a reduced rolling resistance, a good wear resistance and a good wet-skid resistance, while reducing to a minimum the production problems associated to the use of silica as reinforcing filler.

摘要： A method of control to determine the comfort level of a tire of a wheel for a vehicle is based on a dynamic tire model with a rigid ring having concentrated parameters that represent construction characteristics of the tire. Some concentrated parameters are measured, others are determined by parametric identification through a test of passing over an obstacle of the tire. From testing eight curves of natural frequencies and dampenings are obtained that are compared with as many calculated curves obtained from the model. By checking the coincidence between the eight calculated curves and the eight experimental curves, the values of the other concentrated parameters are determined that cause the calculated frequencies and dampenings to coincide with the experimental ones. The values of the concentrated parameters obtained in this way are compared with ranges of values of dampenings and stiffness corresponding to pre-established indices of comfort, so as to approve those tires wherein the concentrated parameters fall within predetermined intervals.

摘要： A device for a braking and traction test of a wheel integral with a hub that is free to rotate, comprises a road-wheel, a crank integral with the hub and a connecting rod that causes the reciprocating movement of a piston sealingly sliding in a chamber of a cylinder containing air. The piston exerts on the wheel and on the tire a sinusoidal torque consisting in a braking torque during its compression stroke and in a traction torque during its expansion stroke. The device also comprises a first deformation transducer associated with the hub and a second and a third speed transducer associated with the hub and with the road-wheel, respectively.

摘要： A torsional vibrator comprises a direct-current electric motor provided with induced windings supplied with direct current through inverter means capable of changing their polarity in an alternating manner with a preselected frequency. To a shaft of the electric motor a wheel is made integral that is formed by a rim and by a tire and acceleration transducers are associated with the rim and with the tire of the wheel. The shaft of the motor is driven to execute angular oscillations that torsionally excite said wheel and cause it to vibrate in rotational direction. The acceleration transducers detect rotational vibrations and provide measurements of acceleration of the rim and of the tire.

摘要： The distribution of a specific pressure in the ground-contacting area of a tire (4) under examination is detected by means of a plurality of sensing cells (7) distributed on a plate-like support (8) applied to a rest surface (2) acted upon by the tire through its rolling surface (5). Each sensing cell (7) sends an electric signal correlated with the specific pressure applied thereto to a processing unit (10) through which the processed signals are sent to a display device (12) graphically representing the distribution of the specific pressure in the ground-contacting area. By causing the tire (4) to roll on the rest surface (2) and therefore the sensing cells (7), the dynamic variation of the specific pressures in the ground-contacting area can be detected. A protection sheet (11) interposed between the rolling surface of the tire (4) and the sensing cells (7) protects the latter against risks of damages due to tangential shearing stresses produced at the ground-contacting area.
