摘要： The invention relates to an assembly (90) for a tyre, which includes: an assembly (24) including: a first impregnated woven or knitted structure including a first woven or knitted fabric (26) and a first layer of a first polymer composition (34); a second impregnated woven or knitted structure including a second woven or knitted fabric (28) and a second layer of a second polymer composition (36); and a supporting structure including supporting element interconnecting the first and second woven or knitted fabric(s); and at least one sacrificial means (62) for temporarily holding the first and second impregnated woven or knitted structures relative to one another, interconnecting the first and second woven or knitted fabric(s), the sacrificial means being arranged so as to break before the supporting elements (32) when the first and second impregnated woven or knitted structures are separated from one another.

摘要： The present invention relates to a tyre-type device (1) for equipping a vehicle, having an improved flattening of the tread thereof compared to a standard tyre. The tyre-type device (1) comprises two revolving structures, radially outer (2) and radially inner (3) respectively, a carrier structure (6) made from identical carrier elements (61), being extended outside of the content area (A) with the ground and compressed in the contact area (A), and two sidewalls (9). The carrier elements (61) are wire elements and are respectively connected to the radially inner face (23) of the radially outer revolving structure (2) by a radially outer fabric (71) and to the radially outer face (33) of the radially inner revolving structure (3) by a radially inner fabric (72). In addition, the mean area density D of the carrier elements (61) per unit area of the radially outer revolving structure (2), expressed in 1/m
2 , is at least equal to (S/S
E )*Z/(A*F
r ), where S is the area, in m
2 , of the radially inner face (23) of the radially outer revolving structure (2), S
E is the connecting area, in m
2 , of the radially outer fabric (71) with the radially inner face (23) of the radially outer revolving structure (2), Z is the nominal radial load, in N, A is the contact area with the ground, in m
2 , and F
r is the breaking strength, in N, of a carrier element (61).

摘要： The invention relates to an antifall device for a two-wheeled vehicle aimed at preventing the falling of the vehicle and its driver, when the rake angle reaches the limit angle corresponding to the limit of road holding of the tyres, for a given circular trajectory and a given road holding coefficient, whilst allowing the measurement of this limit angle. This objective has been achieved, according to the invention, by an antifall device (2) for a two-wheeled vehicle (1) equipped with tyres, the centre of gravity (G) of the vehicle moving over a circular trajectory of centre O and of radius R at a speed V, the mid plane (P) of the vehicle, containing the centre of gravity (G), forming together with the vertical plane (XZ) tangential to the trajectory a rake angle (C), the rake angle (C) increasing with the speed V of the vehicle and varying between a zero angle and a limit angle (C
lim ) beyond which there is a loss of transverse road holding of the tyres entailing the falling of the vehicle, the antifall device (2) being fixed laterally on the side of the vehicle interior to the trajectory and limiting the rake angle (C), when the speed V increases, to a maximum angle (C
max ) strictly greater than the limit angle (C
lim ), the antifall device (2) comprising a safety wheel (3) with centre (G
1 ), whose mid plane (P
1 ) cuts the mid plane (P) of the vehicle along a straight line situated above the ground and forming an angle (a) which differs from the maximum angle (C
max ) by at most 5°, a means of adjustment (4) of the maximum angle (C
max ) and a means of linking (5) between the safety wheel (3) and the vehicle (1).
