[0003] Description
[0004] Vehicle tires
[0005] The invention relates to a vehicle tire.
[0006] The invention relates to a vehicle tire comprising:
[0007] a) a tire carcass comprising a first side area, a second side area and a central area arranged between them, comprising at least one carcass ply with a plurality of rubberized reinforcing elements, each extending through the first side area, the second side area and the central area of the tire carcass,
[0008] b) a tread located radially further outwards relative to the tire carcass,
[0009] c) a tire inner layer located radially further inwards relative to the tire carcass,
[0010] wherein at least some of the rubberized reinforcing elements of the carcass layer enclose an angle of 80° to 90° in the circumferential direction in the first side area and in the second side area, and enclose an angle of 5° to 75° in the central area.
[0011] A damping element is arranged on the inner layer of the vehicle tire.
[0012] The damping element is made, for example, of a porous material or a foam-like material, in particular polyurethane.
[0013] The circumferential direction can be described in particular as the direction of rotation of the vehicle tire. The direction of rotation is the direction in which the vehicle tire can rotate around an axis of rotation.
[0014] Internal202405615
[0015] 2
[0016] Vehicle tires are known from the prior art. These tires, in particular, have a carcass with a first side section, a second side section, and a central section arranged between them. The carcass comprises at least one carcass ply with a plurality of rubberized reinforcing elements, each extending through the first side section, the second side section, and the central section of the carcass. At least some of the rubberized reinforcing elements of the carcass ply form an angle of 80° to 90° with respect to the circumferential direction in the first and second side sections, and an angle of 5° to 75° in the central section.
[0017] The tire carcasses arranged in vehicle tires according to the state of the art are in particular formed from one or more carcass layers, each comprising a large number of rubberized, i.e. embedded in a cross-linked rubber compound, reinforcing elements.
[0018] The radial direction of a vehicle tire is a direction perpendicular to the tire's axis of rotation. A radial direction runs parallel to the radius of a pneumatic tire. The radius of a vehicle tire is the radius of the circle whose shape the tire essentially follows in its direction of rotation; this radius is perpendicular to both the axis of rotation and the direction of rotation. "Radially further out" means, relative to the axis of rotation, that the first component of the tire, which is radially further out than the second component, is located farther from the axis of rotation than the second component. "Radially further in" means, relative to the axis of rotation, that the first component of the tire, which is radially further in than the second component, is located closer to the axis of rotation than the second component.
[0019] In a radial tire known from the prior art, the rubberized reinforcing elements of the carcass plies run essentially radially. This means that the rubberized reinforcing elements extend over an entire 202405615
[0020] 3
[0021] The width of the carcass, perpendicular to the circumference of the vehicle tire, forms an angle of approximately 90° with the circumference. This angle can also be referred to as the cord angle of the reinforcing elements present in the carcass layer. Based on the definition of this cord angle as a function of the circumference, it is particularly possible for a person skilled in the art to determine the cord angle, i.e., the relative angle of the reinforcing element to the circumference.
[0022] The carcass of the vehicle tire according to the invention has three areas: a first side area, a central area, and a second side area. The central area can advantageously be the part of the tire carcass located below the tread in the vehicle tire, whereas the first and second side areas, for example, form the carcass in the area of the sidewalls or sides of the vehicle tire.
[0023] The central area lies radially further inwards than the tread.
[0024] According to the invention, the vehicle tire deviates from a strictly radial construction by using a largely radial arrangement of the reinforcing elements, i.e., with a cord angle of 80° to 90°, only in the first and second sidewall areas. Within the central area of the carcass, however, a cord angle of 5° to 75° is used, resulting in a tire carcass that can be described as a partially angled tire carcass. A cord angle of 5° to 75° means that the rubberized reinforcing elements of the tire carcass form an angle of 5° to 75° with the circumferential direction or the direction of rotation.
[0025] These vehicle tires, known from the prior art, in which cord angles within the central area of the carcass are set in the range of 5° to 75°, exhibit sufficient mechanical stability. Sufficient stability means, in particular, that the vehicle tire can withstand the stresses during normal operation. 202405615
[0026] 4
[0027] These vehicle tires, known from the prior art, could be remanufactured, for example, after use in regular operation. Regular operation refers specifically to operation on roads with specific road surface conditions and at rolling speeds for which the vehicle tire is technically designed and intended. The reason for the possibility of remanufacturing the vehicle tire is primarily due to the fact that the partially angled tire carcass ensures sufficient mechanical stability, such that, for example, a single belt ply of the vehicle tire is designed and used to further increase its mechanical stability. The fewer belt plies a vehicle tire has, the more suitable it is for remanufacturing.
[0028] As part of tire reconditioning, it can be beneficial to replace the damping elements of the vehicle tire, as these may be worn. With tires known from the prior art, the attachment of damping elements to the inner tire surface may be such that detaching a damping element from the inner surface requires significant technical effort and, in particular, is not residue-free. This can be the case, for example, if a damping element is directly bonded to the inner tire surface using an adhesive. In such cases, complete separation of the damping element from the inner tire surface might not be possible initially, and components of the damping element could remain on the inner tire surface.This remaining gap could necessitate further, costly processing of the inner tire surface and could be associated with significant financial costs and environmental burdens.
[0029] The invention is therefore based on the objective of providing a vehicle tire that can be remanufactured and equipped with a new damping element in a less complex manner than is possible with vehicle tires known from the prior art. 202405615
[0030] 5
[0031] The problem set out in the invention is solved by arranging the damping element on the inner tire layer by means of a connecting device, wherein the connecting device comprises a first material bonding component, a support component, and a second material bonding component, wherein the support component is spatially arranged between the first material bonding component and the second material bonding component, and wherein the first material bonding component is connected to the support component and is materially bonded to the inner tire layer, and wherein the second material bonding component is connected to the support component and is materially bonded to the damping element. In particular, the first material bonding component is materially bonded to the support component and / or the second material bonding component is materially bonded to the support component.
[0032] The inventive feature, in which the damping element is arranged on the inner tire layer by means of a connecting device, wherein the connecting device comprises a first material bonding component, a support component, and a second material bonding component, wherein the support component is spatially arranged between the first material bonding component and the second material bonding component, and wherein the first material bonding component is connected to the support component and is materially bonded to the inner tire layer, and wherein the second material bonding component is connected to the support component and is materially bonded to the damping element, avoids, for example, a direct material bond between the damping element and the inner tire surface. This is because the support component is spatially arranged between the damping element and the inner tire surface.This prevents components of the damping element from remaining on the inner surface of the tire during and after the damping element is removed from the vehicle tire. 202405615.
[0033] 6
[0034] This results in an improved vehicle tire that can be remanufactured and equipped with a new damping element in a less complex manner than would be the case with vehicle tires known from the state of the art.
[0035] The vehicle tire could be, for example, a car tire, a truck tire, or a two-wheeler tire.

This angle is the angle of the rubberized reinforcing layers to the circumferential direction.
[0039] According to a further preferred embodiment of the present invention, the tread strip is arranged at least partially, preferably completely, above the central area in a radially outward direction.

[0045] According to a further preferred embodiment of the present invention, the tire carcass comprises two or more carcass layers, wherein in each carcass layer at least a portion of the rubberized reinforcing elements, preferably all of the rubberized reinforcing elements, enclose an angle of 80° to 90° in the first side region and in the second side region, and an angle of 5° to 75° in the central region, relative to the circumferential direction of the vehicle tire. This angle is the angle of the rubberized reinforcing elements to the circumferential direction.
[0046] According to a further preferred embodiment of the present invention, the tire carcass comprises two carcass layers, wherein the rubberized reinforcing elements of the two carcass layers form an angle relative to each other in the central region in the range of 30° to 90°, preferably in the range of 40° to 80°, particularly preferably in the range of 50° to 70°, and most preferably in the range of 55° to 65°. 202405615
[0047] 8
[0048] The inventive feature, in which the tire carcass comprises two carcass layers, wherein the rubberized reinforcing elements of the two carcass layers form an angle relative to each other in the central region of 30° to 90°, preferably in the range of 40° to 80°, particularly preferably in the range of 50° to 70°, and most preferably in the range of 55° to 65°, results in a cross-lamination of the two carcass layers. This cross-lamination leads to an increase in the mechanical stability of the vehicle tire.
[0049] According to a further preferred embodiment of the present invention, at least one further layer, preferably exactly one further layer, is arranged in the vehicle tire between the tread and the tire carcass.
[0050] The next layer could be, for example, a belt of the vehicle tire or a cap ply of the vehicle tire.
[0051] According to a further preferred embodiment of the present invention, at least one of the further layers is a belt layer, wherein the further layer preferably comprises rubberized reinforcing elements which, particularly preferably with respect to the circumferential direction of the vehicle tire, enclose an angle in the range of 10° to 70°, more preferably in the range of 15° to 55°, and even more preferably in the range of 20° to 35°. This angle is the angle of the rubberized reinforcing elements to the circumferential direction.
[0052] According to a further preferred embodiment of the present invention, at least one of the further layers is a cap-ply layer, wherein the further layer preferably comprises rubberized reinforcing elements which particularly preferably enclose an angle in the range of 0° to 5° with respect to the circumferential direction of the vehicle tire. 202405615

[0054] According to a further preferred embodiment of the present invention, the damping element has a radial height of at least 20 mm to 30 mm.
[0055] The radial height of a vehicle tire runs parallel to its radius. This radius is the radius of a circle, the shape of which the tire essentially follows.
[0056] According to a further preferred embodiment of the present invention, the damping element has a uniform axial width.
[0057] The ratio of the width of the damping element to the width of the central area, both perpendicular to the circumferential direction of the vehicle tire, is in the range of 0.25 to 0.95, preferably in the range of 0.3 to 0.85, particularly preferably in the range of 0.35 to 0.8, and most preferably in the range of 0.4 to 0.7.

Furthermore, a larger design of the damping element is not required. The design of the damping element relates in particular to its geometric dimensions. The fact that a larger design of the damping element is not required particularly limits the amount of material from which the damping element is formed.This limitation conserves resources and is environmentally and climate-friendly. 202405615.
