    [0001] [001] The invention focuses, in general terms, on vehicle tires and, more specifically, on a tread pattern aimed at steerable tires intended for commercial truck applications. Fundamentals of the Invention
    [0002] [002] Commercial truck steerable tires are necessary to provide an adequate standard in terms of performance in the presence of snow and wet tracks, with a view to preserving the performance and efficiency of the fuel efficiency achieved by the tire. In addition, it is sought that such types of tires offer a high standard of stiffness in the corner rounding and resistance to the wear of the tread in order to achieve the prolongation of the tire tread's useful life. Consequently, there is a need to obtain a commercial truck steerable tire incorporating a tread pattern that functionally meets the competitive criteria providing conditions for a user to be provided with an acceptable overall tire performance. Summary of the Invention
    [0003] [003] According to one aspect of the invention, a vehicle tire includes a tread containing a circumferential central rib in the tread and one or more intermediate ribs laterally adjacent to the central rib, where each intermediate rib is spaced apart. from the central rib by a circumferential groove in the tread. A circumferential arrangement of discrete tie bar block elements is positioned within the tread groove, with the adjacent tie bar elements within the first circumferential arrangement separated by a circumferential spacing distance. Each link bar block element has a circumferentially oriented bisection cut extending towards an upper surface of the link bar block element to a base end of the block element, with the bisection cut extending in a circumferential direction through the tie bar block element to form the opposing tie bar components. The bisection cut divides each tie bar block element into opposing tie bar components, operationally flexible and converging axially when present inside the tire's tread pattern, operationally closing the radially facing cutting segment. outside and setting a nominal separation dimension when outside the tire tread print area.
    [0004] [004] In another aspect, the bisection cut inside each connecting rod block element forms, next to the radially inward end, a fluid conduction channel extending through the connecting rod block element, with the groove having a dimension in nominal channel width greater than the dimension in nominal width of the cut segment radially facing out of the bisection cut.
    [0005] [005] The invention, in yet another aspect, makes use of multiple circumferential arrangements of link bar block elements constructed within this shape within circumferential depressions on opposite sides of the central rib. Definitions

Fig. 2 consists of a plan view of the tire tread. Fig. 3 consists of a side elevation view of the tire and the tread. Fig. 4 consists of an enlarged plan view of a tread portion. Fig. 5 consists of a section view through the tread region of the tire. Fig. 6 consists of an enlarged section view of a tread region identified in Fig. 5. Detailed Description of the Invention
    [0027] [027] Taking Figs 1, 2, 3, and 4 as an initial reference, there is a tire 10 provided with a circumferential tread region 12. The tread 12 includes a circumferential central rib 22, two circumferential ribs shoulder 14, 16, and a pair of circumferential intermediate ribs 18, 20 positioned on opposite sides of the central rib 22. An equatorial central plane CL divides the tread 12 into two symmetrical halves. A pair of circumferential depressions 28, 30 delimited by the central rib 22 and the separate rib 22 respectively form the laterally adjacent intermediate ribs 18, 20. A pair of raised circumferential depressions 24, 26 respectively separating the intermediate ribs 18, 20 of the protruding ribs 14, 16.
    [0028] [028] In the symmetrical pattern of the tread 12 shown, located within each of the intermediate grooves 18, 20 there is a circumferential arrangement of discrete elements of the connecting bar block 32. Each of the elements of the bar block connection point 32, as seen through Figs, 4, 5, 6 is generally quadrilateral in shape and elongated in a circumferential direction, delimited along the longitudinal sides by means of a respective intermediate rib 18, 20 and by the central rib 22, and along the transverse sides by means of the curved concave sides 34 extending between a respective intermediate rib 18, 20 and the central rib 14. The connecting bar block elements 32 within each circumferential arrangement are spaced apart within a preferred range of 15 to 45 mm. Located within each of the connecting rod block elements 32, an elongated circumferentially oriented connecting rod blade 36 is shown. According to the use given by this report, the word “cut” is used in a sense generic as a divisional separation and not as a reference as to how to form the division. Each tie bar cut divides a respective tie bar block element into a pair of opposing tie bar components 66, 68. Each of the tie bar cuts 36 is formed containing a region or cutting segment upper 38 extending over an upper tie bar surface 37 to a lower tie bar cut region or channel 40 positioned at the base of the cut. The upper cut segment 38 is defined between opposing cut side walls, generally parallel 60, 62. The inner cut channel 40 is of generally circular shape in section, dimensioned presenting a width in diameter W2 within a preferential range of 2 to 4 mm, located near the base of the connecting rod block element. Channel 40 extends circumferentially through the link bar block element and provides a conduit for snow and rain management as described below.
    [0029] [029] As can be seen from Fig. 6, the cuts of the connecting bar 36 are receded radially inwards from a tread surface radially outwardly 58. The depressions 28, 30 where the indentation occurs of the inwardly tapered connecting bars from a dimension of width W, so that each element of the connecting bar block 32 recessed into the respective groove has a width less than the width W of the groove. The connecting bars 32 are therefore dimensioned at an end radially outwardly smaller than the width of the intermediate groove 28, 30 where the block element is located. The width of the intermediate depressions W is within a preferred range of 9 to 15 mm. The cutout 36 within each link bar block element has, within the upper region 38, a width spacing W1 within a preferred range ranging from 0.5 mm to 1.5 mm. The width W1 of the spacing is preselected allowing the link bar block element to close within the tire tread print area radially from the inside to the end of the base region 64. The channel circumferential 40 extending through the base of each connecting bar block element is located next to an end 64.
    [0030] [030] It should be noted that the depressions 28, 30 have a width W next to a tread surface radially outward 58 and a groove depth D within a preferred range of 12 to 18 mm. The connecting bar block elements 32 are recessed into a respective groove 28, 30 and have a height of block element H within a preferred range ranging from 11 to 17 mm. Alternatively, if desired, the tie bar elements 32 can be constructed having the same height as the outer tread surface. Thus, in the new condition, the upper surface 37 pertaining to each link bar block element 32 does not constitute a part of the rolling tire tread impression. After sufficient tread wear has elapsed, the surface 37 of each block member 32 is exposed, becoming part of the tread pattern of the tread.
    [0031] [031] The operation of the tire tread in a rolling tire environment, and in particular, the function of the notched connecting block elements 32, may come to be understood from a joint consideration of Figs 4, 5 and 6. Tire 10 and tread 12 find uses in a wide variety of uses and types of vehicles, and in particular it may be suitable for the case of drivable tires for many kilometers such as commercial trucks. Steerability, as well as driving locations on commercial trucks, can make use of the tread configuration in question. In a typical application, such as in the case of regional commercial trucks, the tread in question gives the ability to offer resistance to the phenomenon of the presence of chips and chunks arising from the adverse conditions encountered on the highways by the tire. The tread configuration reduces the wear of the shoulder and the irregularity of this wear depending on the width of the rib being located within a five-rib model. The central rib 22 and the intermediate ribs 18, 20 are relatively narrow, being within a preferential range of 50 to 80 percent in relation to the relatively wider shoulder grooves 14, 16, presenting a width within a preferential range going from 40 mm to 60 mm. Consequently, the cornering stiffness provided by the tread is increased and the energy from friction is reduced compared to five-ribbed tires containing a conventionally uniform rib pattern. As a result, there is an increase in the mileage provided by the tread in question 12.
    [0032] [032] The arrangement of link bar block elements 32 inside the central depressions 20, 30 makes the tread more rigid and aids in increasing corner stiffness as well as improving performance for snow and track conditions wet over the life of the tire. The connecting bar elements 32, acting as “stiffness forming elements”, strengthen the tread to present a better corner rounding and a better mileage performance. The connecting bar block elements 32, recessed within the respective depressions, are not in contact with the road surface when the tire is new, but establish contact after the tread wears out. As the connecting bar block elements 32 come into contact with the road surface, the edges next to the sides 34 become the additional edges in the tread print area. The channel region 40 pertaining to each connecting rod block element consists of an air and water duct intended to direct air and water through the block elements. By allowing air to pass through the block elements, the trapped air is eliminated, reducing the noise level of the tread. In addition, by providing conditions for the passage of water through channels 40, the potential for flooding is eliminated.
    [0033] [033] In the construction pertinent to five ribs of the tire tread region 12, there is an increase in the gross net rate, defined as the net contact area (area covering the pattern of the tire tread in contact with the flat surface, excluding the area of depressions or other empty spaces for a defined load and inflation) by the gross contact area (area covering the tread pattern in contact with a flat surface including the area of depressions or other empty spaces for a defined load and inflation). The addition of the tie bar block elements 32 increases the Kyy (lateral stiffness) of the tread without impacting the Kxx (circumferential stiffness) of the tread. The blade cuts 36 extend through the block elements 32 from the top surface to the base 64 bisecting the block into halves of opposite block components in the circumferential direction. The tie bar is nominally open through the spacing dimension W1 when the tie bar is outside the tread pattern of the tread. When the link bar block element 32 enters the tread print area of the rolling tire, the blade cut 36 is concentrated in the axial direction, joining the two touching component parts together. Resulting in that the Kyy (lateral stiffness) of the tread within the tread print area of the tread is increased when the tie bar is within the tread area of the tire, improving the stiffness of the corner rounding and reducing frictional energy. When a tie bar leaves the tread print area, the tie bar separates in the axial direction, while the blade cut 36 is reopened in the original spacing W1. Link bar block elements 32 assist in improving the tire's mileage performance by strengthening its stiffness and reducing the tread wear from the effects of loading on the sides of the tire. The configuration with a wider shoulder rib further reduces the shoulder wear phenomenon. As the tread wears out, the tie bar block elements 32 become elements in contact with the road and the edges define the additional contact edges of the tie bars to improve traction.
    [0034] [034] It should be noted that the nominal width W1 of the blade cut 36 is preselected to facilitate the closing of the cut 36 when within a tread print area of the rolling tire and the opening of the cut 36 when outside the tread print area. The dimensions D, H, W, W2, and W1 provided in this report in the form of preferred strips can be modified to dimensions outside the identified strips to suit a particular tread pattern and the material composition of the tread without deviating from the scope of the invention.
    [0035] [035] From the description provided it can be understood that the tread of the vehicle tire 12 is durable and provides with improved performance characteristics. The tread 12, configured to have one or more circumferentially spaced arrangements of discrete elements of the connecting bar block 32 within the respective circumferential tread depressions 28, 30, alter the characteristics regarding the tread stiffness without compromising the wear and circumferential resistance characteristics of the tread. Each tie bar block element 32 has a circumferentially oriented bisection cut 36 effecting the division of the tie bar into opposing tie bar components 66, 68. Consequently, the opposite tie bar components 66, 68 function in a way flexible and converge axially when present inside a tread print area closing the cut segment radially outward 38. The tie bar when present inside the tread print strengthens overall tread stiffness and improves corner puncture, wear, and tire tread handling performance. The opposing tie bar components 66, 68 complete a nominal separation dimension when on the outside of a tread pattern. The bisection cut 36 inside each connecting rod block element 32 further forms, next to a radially inward end, the large diameter fluid conduction channel 40 extending through the connecting rod block element to pass the fluid along the circumferential groove where the connecting rod block element is located. The arrangement of the connecting bar block elements does not, therefore, obstruct the functional performance of the groove where the block elements are located, and the fluid, such as rain or melted snow, is able to pass through the circumferential groove. unobstructed by the arrangement of the block elements of the connection bar. The tire tread provides conditions for high mileage and durability desired by the user.
    [0036] [036] The variations of the present invention are possible in view of the description of the same provided by means of this report. While certain modalities and representative details have been presented for the purpose of illustrating the invention in question, it should be evident to experts in the field that various changes and modifications can be made without deviating from the scope of the invention in question. Therefore, it should be understood that changes can be made in the particular modalities described fully inserted within the intended scope of the invention defined through the table of claims provided below.
