Definitions
- the present invention relates to tires for vehicles of the heavy truck type and more particularly the treads of such tires intended to equip the drive axles of heavy goods vehicles.
- a tire for heavy goods vehicles such as trucks, buses, tractors, comprises a carcass reinforcement comprising a plurality of reinforcements arranged radially, that is to say forming an angle equal to or close to 90 degrees with the circumferential direction, this carcass reinforcement itself being surmounted by a crown reinforcement extending in the circumferential direction.
- This crown reinforcement is itself surmounted on its radially outer surface by a tread made with at least one rubber mixture whose radially outermost part forms a running surface intended to come into contact with the roadway. while driving the tire.
- the tread that is to say the part of the tire intended to come into contact with the ground when rolling and to wear during rolling, a sculpture formed of relief elements delimited by grooves that are circumferentially, transversely or obliquely.
- the purpose of such a sculpture is to give the tread good performance in driving on dry pavement and on pavement covered with water especially in rainy weather.
- the incisions of the grooves are distinguished in that that the incisions have a width suitable to allow during the rolling an at least partial contact between the walls vis-à-vis delimiting these incisions and in particular during the passage in contact with the ground, which can not be the case for the grooves under the normal conditions of use of the tire.
- partial wear of a tread means a state of wear corresponding to a tread thickness at most equal to the total thickness of the band that can be worn before having to change the tire, in particular for regulatory reasons. .
- the patent application WO 02/38399-A2 describes a tread for a truck tire, this tread comprising a plurality of circumferential and transverse grooves.
- the transverse grooves are formed of an alternation of hollow zones and incisions so as to have a volume of hollow opening on the running surface in new condition and a volume of hidden hollows, these hidden hollows being intended to open after partial wear of the same tread.
- the presence of hidden hollows - appearing with wear allows for greater rigidity in the initial state while ensuring adhesion performance regardless of the level of wear of the strip.
- the patent application WO 2011/039194 A1 describes a new type of tread sculpture according to which the durability of the performance of a tread is obtained thanks to a particular management of the trough volumes in said tread. rolling.
- a tread for a truck tire which is provided with at least one groove delimited by side walls vis-à-vis, this groove opening on the rolling surface discontinuously in a plurality of portions open towards the outside of the strip, the side walls being connected by a portion forming the bottom of the groove.
- These open portions comprise two ends extending under the running surface by first channels, the channels having inputs connected to the ends of the open portions.
- Each of these grooves offers a new drainage capacity through continuity with the channels; this drainage capacity is filled in the worn state since in combination with these first channels the second continuous channels are formed integrally under the running surface, these second channels being or not connected to the first channels.
- this type of groove allows - while ensuring the minimum level of drainage through the presence of a suitable hollow volume and open on the tread surface - to keep at the tread of rigidities, especially shear, which are greater than those of bands provided with grooves having depths at least equal to the thickness of the material to be used during rolling.
- the hollow volume ratio of a sculpture of a tread in the new state is equal to the ratio between the volume of the troughs (formed in particular by grooves, incisions, cavities) delimited by the elements of the tread. relief (blocks, ribs) and the total volume of the tread comprising the volume of material to be used and the volume of the troughs.
- a low trough rate indicates a low void volume relative to the tread volume. For each level of wear, one can also define a volume of hollow.
- the surface trough ratio of a sculpture of a tread is equal to the ratio between the surface of the troughs on the tread surface at a given state of wear relative to the surface of the tread surface at which the surface of the hollows is added to the running surface.
- This surface trough rate can be evaluated in new condition and at different levels of wear of the strip. It is known that this rate of surface hollows should be if possible constant if we want the durability of performance with wear.
- a block is a raised element formed on a tread, this element being delimited by recesses or grooves and comprising side walls and a contact face, the latter being intended to come into contact with the roadway during the rolling.
- a rib is a raised element formed on a tread, this element being delimited by two grooves.
- a rib comprises two side walls and a contact face, the latter being intended to come into contact with the roadway.
- the total thickness E of a tread is measured, on the equatorial plane of the tire provided with this band, between the running surface and the radially outermost part of the crown reinforcement to new condition.
- a tread has a maximum thickness PMU of material to be used in rolling, this maximum thickness PMU being less than the total thickness E.
- radial direction means a direction which is perpendicular to the axis of rotation of the tire (this direction corresponds to the direction of the thickness of the tread).
- axial direction means a direction parallel to the axis of rotation of the tire.
- circumferential or longitudinal direction means a direction which is tangent to any circle centered on the axis of rotation. This direction is perpendicular to both the axial direction and a radial direction.
- a cutout generically designates either a groove or an incision and corresponds to the space delimited by material walls facing each other and spaced from each other by a non-zero distance (referred to as "width of the cutout "). What differentiates an incision from a groove is precisely this distance; in the case of an incision, this distance is appropriate to allow the at least partial contact of the opposite walls delimiting said incision at least during the passage in the contact with the roadway. In the case of a groove, the walls of this groove can not come into contact with one another under the usual conditions of rolling.
- the conditions of use of the tire as defined in particular by the standard E.T.R.T.O., specify the reference inflation pressure corresponding to the load capacity of the tire indicated by its load index and its speed code.
