Abstract:
A tire is provided that includes a crown with a mid-plane S, two sidewalls, a first bead, of diameter Φ1, intended to be positioned on the outboard side of a vehicle, and a second bead, of diameter Φ2, intended to be positioned on the inboard side of a vehicle, such that Φ1>Φ2. When the tire is mounted on its working rim and inflated to its nominal pressure, the mid-plane S of the crown is axially offset towards the first bead relative to a mid-plane B of the beads by a positive or zero distance D.
Abstract:
A tire for an axle of a private passenger vehicle having two axles. The axle comprises a suspension device for positively controlling the camber of the wheels relative to the ground in the case of transverse acceleration. The tire develops a contact patch on the ground, said contact patch having a length at the left shoulder (Leg), a length at the right shoulder (Led) and a central length (Lc), a contact patch ratio (Rep) being defined by the quotient of the average of the shoulder lengths divided by the central length. The tire contact patch ratio is greater than 0.65.
Abstract:
The tool which contains:a support, andan arm bearing a strip extrusion member and a strip applicator roller, wherein the arm is articulated with respect to the support about a first axis parallel to a geometric axis of the roller and about a second axis tangential to a circumference of the roller, of the first and second axes at least one passing through a centre of gravity of the arm.
Abstract:
A tire comprising at least one carcass-type reinforcing structure and comprising a crown reinforcing structure having at least one working layer. At least one working layer is radially on the inside of at least one carcass layer, in the sidewalls, the tire comprises at least two carcass reinforcing layer portions extending over a radial distance at least equal to 50% of the radial distance between an end of a shoulder and the radially inner end of the radially innermost circumferential reinforcing element, at least in the equatorial plane, the reinforcing elements of the carcass reinforcement make an angle less than 80°, and the reinforcing elements of the working layer cross with the reinforcing elements of the carcass-type reinforcing structure by an angle greater than 40°, when the tire comprises at least two working layers radially on the inside of at least one carcass layer, the reinforcing elements of the at least two working layers being crossed by an angle of at most 5° and when the tire comprises at least one working layer radially on the outside of the carcass-type reinforcing structure, the reinforcing elements of the at least one working layer crossing with the reinforcing elements of at least one working layer radially on the inside of at least one carcass layer by an angle of at least 30°.
Abstract:
An assembly including a tire having beads, said bead axially including outside the turn-up a layer of a material defining a bead outer profile, such that the distance A, between the carcass frame and the bead outer profile, is as defined in formula (Z), B being the distance between the end of the turn-up, said bead including first and second profiles between the carcass frame and the turn-up, the first profile extends from the bead wire and is made of a material having an extension secant modulus at a 10% elongation higher than 20 MPa, a second profile arranged in the bead such as to be in contact with a surface of the first profile and the turn-up, made of a material having an extension secant modulus at a 10% elongation of at least 7 MPa and an extension secant modulus at a 100*% extension of at least 4.5 MPa.
Abstract:
A support device connects a wheel to suspension elements of a vehicle, the wheel having a radius R′. The support device includes rods articulated at their lower ends to the suspension elements and at their upper ends to the wheel carrier so as to confer on the wheel a degree of camber freedom relative to the suspension elements. The camber movement takes place around an instantaneous center of rotation. The device is also configured in such manner that Y and Z are respectively the abscissa and ordinate of the instantaneous position of the instantaneous center of rotation in the camber plane, wherein such position, during a camber deflection from 0° to 1°, satisfies the following conditions: Y≦0.125*R Z≦−0.0625*R Z≦0.66225*Y+0.02028*R.
