Description

Technical Field

[0001] The present invention relates to a vehicle pneumatic tire having a sidewall and a tread, and having at least one hatched area on at least one of the sidewall and / or the tread, wherein the hatched area has hatched elements arranged adjacent to each other, wherein each hatched element has a hatched rib. Background Art

[0002] Such hatched areas are usually molded into the tire during the vulcanization of the tire by means of a shaped vulcanization mold having a negative profile of the hatched area. However, the structured surface of the already vulcanized tire can also be achieved by removal (e.g., by means of engraving) or by an additive process.

[0003] Such hatched areas are known. On the tire sidewall and / or on the tread, these hatched areas are used, for example, to implement markings. The markings may include images, characters, company names, company logos, names, areas, etc. The hatched area may be part of the marking and / or may completely or partially surround the latter.

[0004] The scattering of light on the sides of the shadow line ribs reduces the reflection of light on the tire surface, thus changing the brightness effect. In general, the surface area provided with the transverse protuberances appears darker than the substantially smooth surface area without such protuberances. This makes it possible to achieve contrast in the inherently monochrome surface of the tire, in particular the sidewall and / or the tread. The description of the marking can thus be made more clearly visible.

[0005] For example, DE 10 2012 105 864 A1 discloses a vehicle pneumatic tire having a plurality of hatching ribs on its sidewall for high-contrast surface design and marking highlighting.

[0006] A disadvantage of this embodiment is that the design options are limited. Summary of the invention

[0007] The problem addressed is therefore to influence the contrast effect in a more targeted manner and to increase the contrast effect further. It is also sought to allow improved ventilation capabilities during the production of tires with the aid of a vulcanization mold.

[0008] This is achieved in that each shading element has short transverse ridges which intersect the shading ribs in the intersection region, wherein each short transverse ridge intersects exactly one shading rib.

[0009] It has been found that shadow line elements with short transverse ridges that cross the shadow line ribs in the intersection area produce a significantly stronger contrast effect than shadow line ribs without such intersection areas or without short transverse ridges that cross them. Each short transverse ridge can extend to both sides of the shadow line rib. The additional side of the short transverse ridge increases the scattering, multiple reflections and absorption of the light incident on the shadow line area. In addition, the side of the shadow line rib is interrupted by the short transverse ridges, which further increases the contrast. Multiple reflections on the shadow line elements extending adjacent to each other will further strengthen the effect. In addition, the short transverse ridges produce additional shadow effects, especially on the black rubber of vehicle pneumatic tires, the shadow line area will stand out significantly relative to the surrounding surface area. Since the short transverse ridges each cross exactly one shadow line rib, each short transverse ridge also has two free end areas, which can lead to additional scattering of light in different directions.

[0010] Thus, by means of hatching elements having short lateral ridges crossing them, the contrast effect can be influenced and improved in a more targeted manner.

[0011] The connection of the short transverse ridges and the shadow ribs in the intersection region also allows advantageous ventilation of the structural surface during tire construction. In addition, the short transverse ridges stabilize the shadow element in the intersection region, with the result that the shadow element is more resistant to wear marks during tire use.

[0012] A favourable embodiment is provided, in which the shadow line area has at least two adjacent shadow line elements, the short lateral ridges of the at least two adjacent shadow line elements being oriented parallel to each other, and the short lateral ridge of one adjacent shadow line element being arranged offset relative to the short lateral ridge of another adjacent shadow line element, preferably being arranged offset centrally.

[0013] Here, "displaced" means that the short transverse ridge of one adjacent hatching element intersects another adjacent hatching element between two intersection regions in its extension. Here, "centrally offset" means that the intersection region at least includes the center between two intersection regions.

[0014] In the case of a compact arrangement, the offset arrangement of the short transverse elevations allows a particularly uniform distribution of the short transverse elevations.

[0015] Advantageously, all adjacent cross-hatched ribs are designed in this manner.

[0016] An advantageous embodiment is provided in which the shading ribs of the shading element are arranged at a spacing of 0.4 mm to 1.0 mm, preferably 0.5 mm to 0.7 mm, particularly preferably 0.55 mm to 0.60 mm.

[0017] Such a distance of 0.4 mm to 1.0 mm, preferably 0.5 mm to 0.7 mm, particularly preferably 0.55 mm to 0.60 mm, enables an improved contrast effect with simultaneously low production costs.

[0018] The spacing may be measured between areas perpendicular to the tire surface and extending along the ridges of the hatched ribs.

[0019] An advantageous embodiment is provided in which the intersection regions of at least one of the hatching elements are arranged at a spacing of 0.2 mm to 0.5 mm, preferably 0.25 mm to 0.35 mm.

[0020] Such a spacing allows the short transverse ridges to be arranged closely enough to obtain a favorable contrast effect while being inexpensive to manufacture. The advantages are further enhanced if all cross-hatched ribs are designed in this way. The spacing can be measured between the center points of the intersection areas.

[0021] An advantageous embodiment is provided in which the longitudinal extension direction of at least one of the shadow line ribs encloses an angle of 45° to 90°, preferably 60° to 90°, particularly preferably 90°, with the corresponding longitudinal extension direction of the short transverse ridges intersecting therewith.

[0022] This angle influences the local density distribution on the inclined side adjacent to the intersection zone. However, in the case of an angle of less than 45°, demoulding of the tire becomes more difficult. An angle of 60° to 90° allows an improved contrast effect with good demoulding properties. In the case of an angle of 90°, demoulding properties are further improved.

[0023] It is also advantageous if all short transverse ridges of the hatching element are at the same angle to the corresponding hatching rib. This limits the number of directions that need to be engraved in order to generate a hatching area.

[0024] The advantages are further enhanced if all hatching elements are designed in this way.

[0025] An advantageous embodiment is provided in which the hatching area has at least two adjacent hatching elements, between whose short transverse ridges there is a clear spacing which is at least 10%, preferably at least 13%, of the spacing of the hatching ribs of the adjacent hatching elements.

[0026] The clear distance is measured perpendicularly to the longitudinal extension direction of the hatching element. The clear distance can be measured at a height H3 which corresponds to 1 / 3 of the average of the heights H of two hatching ribs of adjacent hatching elements.

[0027] It has been found that such a clearance further improves the demoulding properties. This also makes it possible to increase the multiple reflections of light on two adjacent hatching elements, with the result that the contrast effect is further increased.

[0028] An advantageous embodiment is provided in which the height H of at least one of the hatching ribs is 0.1 mm to 0.8 mm, preferably 0.2 mm to 0.5 mm, particularly preferably 0.25 mm to 0.35 mm.

[0029] The height H of the shadow rib may be the height averaged along the longitudinal length of the shadow rib. The height may be measured relative to a level corresponding to the average level of the entire shadow base of the marking area. The height may also be measured relative to a level corresponding to the level of a base formed, for example, by a portion of the outer surface of a vehicle pneumatic tire, in particular the base of a shallow depression formed in the tire surface.

[0030] The average usually corresponds to the arithmetic mean.

[0031] In this way, advantageous dimensions are achieved which are beneficial to producibility. It is particularly advantageous if several, preferably all, of the hatching ribs have a corresponding height H.

[0032] Furthermore, a good contrast effect can be achieved by such a depth, in particular in combination with a spacing between adjacent shadow line ribs of 0.4 mm to 1.0 mm, preferably 0.5 mm to 0.7 mm, particularly preferably 0.55 mm to 0.60 mm.

[0033] An advantageous embodiment is provided in which at least one shading element is designed such that its shading ribs have mutually opposite side surfaces which enclose an angle of at least 50°, preferably 55° to 65°, with one another.

[0034] Such side angles exhibit a good contrast effect. For example, a corresponding negative shape of a forming tool (such as a vulcanization mold) can be produced by means of laser engraving. The angle between the intersections can be measured. It is particularly advantageous if the mutually opposite side faces have such an angle in a height range that corresponds to at least one quarter of the height H of the shadow line rib.

[0035] This advantage is also or additionally enhanced if several, preferably all, of the shadow line ribs are formed in this way.

[0036] An advantageous embodiment is provided, in which at least one of the shadow line elements has shadow line ribs and / or short transverse ridges, which respectively have mutually opposite side surfaces, which enclose an angle of 2° to 10°, preferably 6° to 8°, with each other.

[0037] The use of such steep side angles allows multiple reflections and thus an improved contrast effect. A corresponding negative shape of a forming tool, such as a vulcanization mold, can be produced by means of laser engraving of the forming tool. With regard to the hatching ribs, the angle can be measured between two intersection regions. With regard to the short transverse ridges, the angle can be measured outside the intersection region. It is particularly advantageous if the mutually opposite side faces have such an angle within a height range that corresponds to at least one quarter of the height H of the hatching ribs. This advantage is also or additionally enhanced if several, preferably all hatching elements are formed in this way.

[0038] In an advantageous embodiment, the hatching ribs each have mutually opposite sides enclosing an angle of at least 50° with each other, and the short transverse ridges each have mutually opposite sides enclosing an angle of 2° to 10°, preferably 6° to 8° with each other.

[0039] In a further advantageous embodiment, the hatching rib and the short transverse ridge each have mutually opposite side faces which enclose an angle of 2° to 10°, preferably 6° to 8°, with one another.

[0040] It can also be advantageous if the hatching ribs and / or the short transverse ridges have mutually opposite sides and have an average width of 0.08 mm to 0.13 mm, preferably 0.1 mm, which sides enclose an angle of 2° to 10°, preferably 6° to 8°, with one another. The average width is the arithmetic mean of the widths measured at different heights.

[0041] An advantageous embodiment is provided in which the short transverse ribs and / or shading ribs of at least two shading elements, in particular at least two adjacent shading elements, differ from one another by at least 30° with respect to the angles enclosed by their side surfaces.

[0042] In this way, the shadow line area can be further optimized with respect to the target conflict between scratch resistance and contrast.

[0043] Advantageously, adjacent shading elements differ in that the mutually opposing side faces of the shading ribs enclose angles which differ from one another by at least 30°. In this way, a particularly high lateral density can be achieved.

[0044] An advantageous embodiment is provided, in which at least one of the shadow line elements has a shadow line rib and / or at least one short transverse ridge, which has a cross-section having a convex curvature and / or a linear and / or a concave curvature and / or a stepped and / or curved and / or structured area in the region of at least one side.

[0045] The cross section extends outside the intersection region perpendicularly to the longitudinal extension direction of the respective short transverse ridge or hatching rib. In this way, the contrast effect can be influenced in a more targeted manner and can be further increased. This advantage is intensified if several, preferably all, cross-hatching ribs and / or short transverse ridges are formed in this way.

[0046] It is particularly advantageous if the correspondingly shaped region extends over a height range which corresponds to at least one quarter of the height H of the shading ribs of the shading element.

[0047] The shadow line ribs and / or the short transverse ridges may transition to the shadow line base at a bend or in a curved manner.

[0048] The cross section may be symmetrical.

[0049] The short transverse ridges of the hatched and / or cross-hatched ribs may have flat ridges. The ridges may include a plateau with a width of 0.03 mm to 0.06 mm. The ridges may also have an irregular height, the irregularity being at most 5% of the height H.

[0050] Independently of the embodiment, the hatched area can have a hatching base, by means of which adjacent cross-hatched ribs and / or adjacent short transverse ridges are separated from one another. An essentially flat hatching base is preferred.

[0051] An advantageous embodiment is provided in which at least one hatching element has short transverse ridges which slope continuously downward from the intersection region to the hatching base.

[0052] In this way, while achieving the advantageous supporting effect of the short transverse elevations, the demoulding properties are simultaneously further improved.

[0053] In a preferred embodiment, the hatched area is formed on one of the sidewalls of a vehicle pneumatic tire.

[0054] In another preferred embodiment, the hatched area is formed on the tread of the vehicle pneumatic tire. The hatched area can also be applied in particular to the groove side and / or the groove base of the groove extending in the tread, or at the tread exit, that is, at the shoulder side extending to the sidewall outside the contact surface, or on the outer surface of the tread, that is, on the tread in contact with the ground.

[0088] Figure 1 A vehicle pneumatic tire 1 is shown, which has a sidewall 2 and a tread 3 and has at least one hatched area 4 on at least one of the sidewall 2 and / or the tread 3. In the case of being arranged on the tread 3, the hatched area may also be applied in particular to the groove sides and / or the groove base of a groove extending in the tread 3, or at the tread exit, i.e. at the shoulder side extending outside the contact patch to the sidewall, or on the outer surface of the tread, i.e. on the tread in contact with the ground.

[0089] The hatched area 4 has at least two hatched elements 5 extending adjacent to each other, each hatched element having a hatched rib 51 and short transverse ridges 53 intersecting the hatched rib in an intersection region 52 , wherein each short transverse ridge 53 intersects exactly one of the hatched ribs 51 .

[0090] Such design variants of the hatched area 4 are Figure 2 The illustrated cross-sectional view of the hatched area 4 has at least two adjacent hatched elements 5, whose short transverse ridges 53 are oriented parallel to each other. The short transverse ridges 53 of one adjacent hatched element 5 are offset relative to the short transverse ridges 53 of another adjacent hatched element 5, preferably offset centrally.

[0091] The short transverse ridges 53 of the cross-hatched ribs 5 intersect the respective adjacent hatching element 5 in their extension 6 between two intersection regions 52. In the embodiment shown, the respective intersection region 7 comprises at least the center between the two intersection regions 52.

[0092] The spacing 8 between adjacent hatching elements 5 is 0.4 to 1.0 mm, preferably 0.5 to 0.7 mm, particularly preferably 0.55 to 0.60 mm. The spacing 8 can be measured between regions 24 extending perpendicular to the tire surface and along the ridges 18 of adjacent hatching ribs 51 .

[0093] The intersections 51 of the cross-hatched ribs 5 may be arranged at a pitch 9 of 0.2 to 0.5 mm, preferably 0.25 to 0.35 mm. The pitch 9 may be measured between the center points of the intersections 51. In the illustrated example, all intersections 51 have approximately the same pitch 9.

[0094] The longitudinal extension direction 10 of the shading element 51 and the corresponding longitudinal extension direction 12 of the short transverse elevations 53 intersecting therewith respectively enclose an angle 11 of 45° to 90°, preferably 60° to 90°, particularly preferably 90°. An angle 11 of approximately 90° is shown in each case.

[0095] The clear spacing 13 between the short transverse ridges 53 of adjacent cross-hatching ribs 5 may be at least 10%, preferably at least 13%, of the spacing 8 of adjacent hatching elements 5. The clear spacing 13 is measured perpendicular to the longitudinal extension direction 10 of the hatching elements 51. The clear spacing is measured at a height H3, which may be 1 / 3 of the average value of the height H of the hatching ribs 51 of two adjacent hatching elements 5.

[0096] The hatching ribs 51 have a height H of 0.1 mm to 0.8 mm, preferably 0.2 mm to 0.5 mm, particularly preferably 0.25 mm to 0.35 mm, wherein the height H is averaged along the longitudinal length of the respective hatching rib 51. The height H can be measured relative to a level 20 corresponding to the average horizontal level of the hatching base 19. The level 20 can also correspond to a base level formed, for example, by a portion of the outer surface of a pneumatic tire for a vehicle, in particular to a base of a shallow depression formed on the tire surface.

[0097] The shadow ribs 51 each have mutually opposite side faces 14 which enclose an angle 15 of at least 50°, preferably 55° to 65°, with one another. The short transverse ridges 53 each have mutually opposite side faces 14 which enclose an angle 15 of 2° to 10°, preferably 6° to 8°, with one another. It is particularly advantageous if the mutually opposite side faces have such a corresponding angle over a height range corresponding to at least one quarter of the height H of the shadow rib.

[0098] However, the shadow rib 51 and the short transverse elevation 53 can also each have mutually opposite side faces 14 which enclose an angle 15 of 2° to 10°, preferably 6° to 8°, with one another.

[0099] The cross section of the illustrated hatched ribs 51 and / or short transverse ridges 53 has a linearly extending region 16 in the region of at least one side. As shown, this can transition into the hatched base 19 at a bend 17 or in a curved manner.

[0100] The short transverse ridges 53 of the hatched ribs 51 and / or cross-hatched ribs 5 may have flat ridges 18. The ridges may include a platform with a width of 0.03 mm to 0.06 mm. The ridges 18 may also have an irregular height, the irregular amount being at most 5% of the maximum height difference of the hatched area.

[0101] The hatching region 4 can have a hatching base 19 which separates adjacent hatching elements 5 and / or adjacent short transverse ridges 53 from one another.

[0102] Figure 3 Another exemplary embodiment according to the present invention is shown. Figure 2The exemplary embodiment shown in FIG. 1 differs at least in that the short transverse ridges 53 are continuously inclined downward from the intersection region 52 to the shadow base 19. In addition, the side surfaces 14 of the shadow ribs 51 and the short transverse ridges 53 transition into the shadow base 19 in a curved line. Independently of this, the exemplary embodiment also differs in that the shadow ribs 51 of at least two shadow elements 5, in particular at least two adjacent shadow elements 5, differ from each other by at least 30° in terms of the angles 15, 15' enclosed by their side surfaces 14. The angle 15 can be 2° to 10°, preferably 6° to 8°, and the angle 15' can be at least 50°.

[0103] Figure 4a to Figure 4g Examples of cross sections of hatched ribs 51 and / or short transverse ridges 53 of hatched elements are shown. The cross sections extend perpendicularly in each case outside the intersection region 52 relative to the longitudinal extension direction of the respective short transverse ridge 53 or hatched rib 51. The cross sections are suitable for Figure 2 and Figure 3 The hatched area 4 is shown in FIG. Without limiting the general nature, the cross-section shown is symmetrical.

[0104] Figure 4a The cross section is shown with a linearly extending region 16 in the region of the side faces 14. The side faces 14 are opposite to one another and can enclose an angle 15 of at least 50°, preferably 55° to 65°, with one another. The side faces 14 transition to a flat hatched base 19 at the bend.

[0105] Figure 4b A corresponding section is shown, in which the side surfaces 14 enclose an angle 15 of 2° to 10°, preferably 6° to 8°, with one another.

[0106] Figure 4c This is shown by way of example, and regardless of the precise design of the cross section, the side surface 14 can also merge with a curvature into the hatched base 19 .

[0107] Figure 4d A cross section with a convexly curved region 16 in the region of the side surface 14 is shown. Figure 4e A cross section with a stepped region 16 in the region of the side surface 14 is shown.

[0108] Figure 4f A section with a structured region 16 is shown in the region of the side surface 14 . Figure 4g A cross section with a concave curved region 16 in the region of the side surface 14 is shown.

[0109] In all Figure 4a to Figure 4g In the embodiment shown in FIG. 1 , a correspondingly shaped region 16 may extend over at least one quarter of the height H of the hatched rib of the corresponding hatched element.
