Description
Technical Field
The invention relates to the technical field of tires, in particular to a tire pattern rubber ring and a tire assembly with the same.
Background
The conventional tire can not adapt to the driving requirements of different places, and the tire replacement is troublesome when the tire is driven in different places. Taking the off-road tire as an example, the conventional off-road tire mainly considers the use performance of traction, control, ground gripping and the like of a racing mixed road condition when designing the tread pattern and the rubber material, for example, the tread pattern is usually set to be a block pattern and adopts a high sea ratio (the sea ratio is the ratio of the grooves formed between the pattern blocks in the tread area to the total area of the tread) and a soft rubber material, but the wear, the mute comfort, the high speed and the like cannot be considered at the same time. In addition, the movement of the 4 x 4 off-road vehicles between different playing fields is generally carried by trucks, but at present, for convenience and cost saving, some special customers directly adopt a mode of going up a highway or a highway to convert the different playing fields; and because the tread patterns adopt the design modes of block patterns with high sea ratio, soft rubber materials and the like, the tires of the off-road vehicles wear too fast in the running process on hard roads and have poor riding experience.
In order to meet the driving performance requirements of tires under different road conditions, some attempts have been made in the prior art.
The patent with the application number of CN202021600760.3 discloses a replaceable tread tire, which comprises a rim, an inner tube and an outer cover, wherein the replaceable tread is arranged in an attaching and surrounding mode outside the outer cover, the replaceable tread comprises an upper tread and a lower tread, the upper tread is connected with the lower tread through a zipper strip, a pattern unit is arranged at the position of a crown of the upper tread, tire beads are arranged at two ends of the circumferential surface of the rim, a cord fabric layer is arranged on the outer side of each tire bead, and the cord fabric layer is folded and overlapped along the tire beads to form a circle in a surrounding mode. When in use, the replaceable tread on proper road conditions is only needed to be covered with the tire, the used tread is replaced at the position of the bead zipper, and the joint of the upper tread and the lower tread is sewed through the zipper strip.

Therefore, the disclosed technology is not suitable for high-speed running of off-road tires on hard roads.
The KR20170084005 patent discloses a tread pattern variable tire that changes from a block pattern to a rib pattern or from a rib pattern to a block pattern depending on the mounting position of the block pattern tire. The rib tire is modified in the block pattern by mounting a variable pattern chain having a pattern having the same shape as that between the patterns on the block pattern tire so as to form a rib pattern laterally between the block patterns, or by removing the mounted variable pattern chain to provide a tire most suitable for the running condition.
The disclosed technology adopts a pattern variable chain, which is favorable for mounting and dismounting on the tire, and is relatively simple and regular in the shape of a tread pattern block. But for the off-road tire, the tread pattern is complex, and the pattern blocks are irregular in shape and are distributed in a staggered manner; meanwhile, the pattern grooves formed among the pattern blocks are also complicated and complicated, and by adopting the pattern variable chain which is similar to the pattern with the same shape as the pattern between the patterns, the pattern blocks forming the pattern variable chain become very fine and broken, so that the rigidity of the pattern is difficult to ensure; the wear resistance is not beneficial to the running of the off-road tire on a high-speed road; simultaneously at the effectively fixed a plurality of tensioning pieces of decorative pattern piece in small, broken bits, there is the risk that the tensioning piece drops, and complex operation, be unfavorable for installing and use on cross country tire.

Specifically, with reference to fig. 2 to 3, fig. 2 is a partially enlarged schematic view of a three-dimensional structure of a tire tread rubber ring 1 according to a first embodiment of the present invention, and fig. 3 is a schematic view of a planar development structure of the tread rubber ring according to the first embodiment of the present invention. The central connecting portions 121 are located in a central region of the rubber gasket body 11 and are staggered along two sides of a central axis of the rubber gasket body 11 and arranged at intervals 14 along the circumferential direction. The central connecting portion 121 comprises a matching cavity 123 which is matched with the central pattern block 21 in the central area of the tire tread in a nesting mode, the central connecting portion 121 further comprises an expanding wall portion 124 which defines the matching cavity 123, the expanding wall portion 124 is arranged around the central pattern block 21 in a surrounding mode, the expanding wall portion 124 can expand the grounding area of the central pattern block 21, the pattern rigidity of the central pattern block 21 in high-speed running on a hard road is enhanced, the abrasion performance of the tire is improved, and meanwhile the control performance and the comfort performance of the tire in high-speed running are improved. The profile cross section of the expanded wall portion 124 may have the same cross section as the mating cavity 123 or may have a cross section different from the mating cavity 123. The contour surface of the expanded wall portion 124 may surround and seal the center block 21, or may partially form a notch without surrounding and sealing the center block 21.
In fig. 3, the matching cavity 123 constituting the center connecting portion 121 is arranged to have the same contour as the center block 21 of the tire, that is, the cross section of the matching cavity 123 is enclosed and surrounded by a plurality of line segments to form a polygon, and the cross section of the contour of the expanded wall portion 124 of the center connecting portion 121 is also enclosed and surrounded by a plurality of line segments to form a polygon.
Similarly, the cross section of the contour of the expanded wall portion 124 of the central connecting portion 121 may be a non-polygonal pattern such as a circle, an ellipse, or the like formed by a closed circle of a curve, or may be a pattern in which a non-closed partially-formed notch is formed by a curve or a multi-segment line, which is not shown here.
The pattern connecting portions 12 at least protrude from the base 13, and at least a circumferential space 14 and/or an axial space 15 are provided between adjacent central connecting portions 121, wherein the circumferential space 14 refers to a gap between two adjacent central connecting portions 121 arranged along the circumferential space 14, and the axial space 15 refers to a gap between two adjacent central connecting portions 121 arranged along the axial space 15. When the circumferential intervals 14 are formed between the central connecting parts 121, the central pattern blocks 21 in the central area of the tread of the tire assembly when the tire pattern rubber ring 1 is matched with the tire in an embedding way are provided with transverse grooves, so that the rigidity of the central pattern blocks 21 is increased, and the abrasion performance and the traction performance of the tread in the central area are improved; when the axial interval 15 is formed between the central connecting parts 121, the central pattern block 21 in the central area of the tread of the tire assembly when the tire pattern rubber ring 1 is matched with the tire embedding is provided with a longitudinal groove, so that the rigidity of the central pattern block 21 is increased, and the abrasion performance and the handling performance of the tread in the central area are improved.
In the first embodiment shown, the central connecting portions 121 simultaneously form a circumferential space 14 and an axial space 15. Thus, when the central pattern block 21 of the tire and the central connecting part 121 of the tire pattern rubber ring 1 are nested and matched to form the tire assembly, the tire central area is provided with the transverse grooves or the longitudinal grooves or both the transverse grooves and the longitudinal grooves, the pattern rigidity of the tire central area is increased, the grounding area of the tire is increased, the abrasion performance of the tire during running on a hard road surface is ensured, the traction performance and the handling performance of the off-road tire are improved, and the high-speed running performance of the tire is met.
The thickness a of the cross section of the expanded wall portion 124 of the center connecting portion 121 is preferably 3.0mm or more, which is effective to increase the rigidity of the center block 21 and to have a larger ground contact area, ensuring wear performance and comfort performance of the tire when the tire is driven on a hard road at high speed.
A plurality of shoulder connecting portions 122 are provided axially outward of the center connecting portion 121, respectively. The shoulder connecting portions 122 on the same side of the sipe rubber 1 are divided into first shoulder connecting portions 122a and second shoulder connecting portions 122b, which are alternately arranged at intervals in the circumferential direction. The first shoulder connecting portion 122a and the second shoulder connecting portion 122b each have a fitting cavity 123 to be fitted in a tire nesting manner and an expanded wall portion 124. Specifically, the first shoulder connecting portion 122a has a fitting cavity 123 fitted in nesting with the shoulder blocks 22, and the fitting cavity 123 has the same profile surface as the shoulder blocks 22 and is used for nesting and receiving the shoulder blocks 22, so that the pattern rigidity of the shoulder blocks 22 during high-speed running on a hard road is enhanced, and the wear performance of the off-road tire is improved. The expanded wall portion 124 of the first shoulder connecting portion 122a is used for expanding the ground contact area of the shoulder block 22, enhancing the pattern rigidity of the shoulder block 22 when the shoulder block runs on a hard road at a high speed, and ensuring the abrasion performance of the tire when the tire runs on the hard road; meanwhile, the control performance and the comfort performance during high-speed running of the tire are improved; similarly, the second shoulder connecting portion 122b has a mating cavity 123 and an expanded wall portion 124 that are substantially the same as the first shoulder connecting portion 122a, and the profile surface of the expanded wall portion 124 may have the same cross section as the mating cavity 123 or a cross section different from the mating cavity 123; the contour surface of the expanded wall portion 124 may surround and seal the off-road tire body shoulder block 22, or may partially form a notch without surrounding and sealing the off-road tire body shoulder block 22.
With reference to fig. 1 to fig. 2, the three-dimensional structure of the tread rubber ring of the first embodiment is schematically illustrated, wherein a notch 1221 is formed on the axially outer side of the expanded wall portion 124 of the second shoulder connecting portion 122 b; and the first shoulder connecting portion 122a forms an expanded wall portion 124 in a closed surrounding form.
Referring again to fig. 1-4, the pattern connecting portions 12 protrude at least beyond the base 13, and adjacent shoulder connecting portions 122 have at least a circumferential spacing 14 and/or an axial spacing 15 therebetween. The circumferential space 14 refers to a gap between two adjacent shoulder connecting portions 122 (e.g., a first shoulder connecting portion 122a and a second shoulder connecting portion 122 b) arranged along the circumferential space 14, and the axial space 15 refers to a gap between two adjacent shoulder connecting portions 122 arranged along the axial space 15. When the shoulder connecting portions 122 have the circumferential spacing 14 therebetween, the shoulder blocks 22 when the tire tread rubber ring 1 is fitted with a tire have lateral grooves; the shoulder blocks 22 when the sipe rubber 1 is in nested engagement with a tire have longitudinal grooves when there is an axial space 15 between the shoulder connecting portions 122. The tire has the advantages that the pattern rigidity of the shoulder area of the tire is increased, meanwhile, the grounding area of the tire is increased, and the abrasion performance of the tire in running on a hard road surface is improved; meanwhile, the traction performance and the control performance of the tire are improved, and the high-speed running performance of the off-road tire is met.
On the contrary, no circumferential space 14 and/or no axial space 15 are provided between the adjacent shoulder connecting portions 122, that is, the shoulder regions of the tread rubber ring 1 are connected by the expanded wall portions 124; when the tread rubber 1 is fitted into the tire, the rigidity of the shoulder area of the tire is too high, and uneven wear may occur in the shoulder area and the center area, which may adversely affect the high-speed running performance of the tire.
In addition, the height H1 of the center connecting portion 121 and the height H2 of the shoulder connecting portion 122 of the tread rubber ring 1 are respectively consistent with the height of the center pattern block 21 and the height of the shoulder pattern block 22 of the tire, so that when the tread rubber ring 1 is nested and matched with the tire to form the tire assembly, the tire assembly has excellent wear performance, meanwhile, the comfort performance of high-speed running of the tire is improved, and the high-speed performance requirement of a customer is met.
As shown in fig. 1 to 4, the center connecting portion 121 and the shoulder connecting portion 122 of the bead 1 are integrally connected to the base 13 except for the fitting cavity 123 for fitting the block of the tire, and the thickness H of the base 13 in the radial direction is preferably (0.2 to 0.5) of the height H1 of the center connecting portion 121 of the bead 1. The thickness of the substrate 13 is too thick, which causes material waste; if the base 13 is too thin, the overall strength of the tread rubber 1 is insufficient to affect the nesting fit with the tire.
In order to ensure that the tire pattern rubber ring 1 can be well nested and matched with a tire, the tire pattern rubber ring 1 is made of a high-elasticity rubber material, and meanwhile, the nested and matching of the tire pattern rubber ring 1 and the tire and the separation of the tire pattern rubber ring 1 from the tire are facilitated; further, the rubber material of the tread rubber 1 has a storage modulus higher than that of the rubber material of the tire tread, and more preferably, at 60 ℃.
Further, the extension 16 is connected to the base 13 and extends beyond the axially outer side of the shoulder connecting portion 122; the inside of the extension part 16 can be provided with a reinforcing part 17, and the reinforcing part 17 can be formed by reinforcing elements such as steel wires, fibers and the like and is used for reinforcing the nesting fit of the tire pattern rubber ring 1 and the tire so as to ensure the high-speed driving performance of the tire on a hard road surface.
When the vehicle needs to adopt the high speed or the highway to switch different competition fields, the tyre assembly with the tyre pattern rubber ring 1 is formed only by nesting and attaching the tyre pattern rubber ring 1 to the tread area of the existing tyre. The pattern blocks of the tire respectively penetrate through the central connecting part 121 of the tire pattern rubber ring 1 and the matching cavities 123 of the shoulder connecting parts 122, so that the central connecting part 121 of the tire pattern rubber ring 1 and the matching cavities 123 of the shoulder connecting parts 122 are respectively nested and matched with the central pattern blocks 21 and the shoulder pattern blocks 22 of the tire tread, the rigidity of the tread pattern blocks of the tire is enhanced, and excessive abrasion of the tread of the vehicle tire is avoided when the vehicle tire runs on a hard road at a high speed; the central connecting part 121 of the tire pattern rubber ring 1 and the expanded wall part 124 of the shoulder connecting part 122 are nested and matched with the pattern blocks to form a tread pattern with a larger ground contact surface, so that the pattern rigidity of the tread pattern of the tire is improved; meanwhile, the traction performance and the control performance of the tire running on a high-altitude road surface are improved, and the comfortable high-speed performance experience required by customers is met.
Fig. 5 is a schematic plan view showing a structure of the tread ring 1 according to the second embodiment of the present invention. This embodiment is different from the first embodiment in that the pattern connecting portion 12 is divided into only the center connecting portion 121. The tire tread rubber ring 1 comprises a plurality of central connecting parts 121, and the central connecting parts 121 are alternately arranged at intervals and are connected into a whole by a base 13. The central connecting portion 121 includes a mating cavity 123 and an enlarged wall portion 124 that defines the mating cavity 123. The matching cavity 123 has the same outline as the pattern of the central area of the tire tread and is used for nesting and receiving the central pattern block 21 of the tire body, so that the pattern rigidity of the central pattern block 21 is enhanced when the central pattern block runs on a hard road surface at high speed, and the abrasion performance of the tire is improved.
The expanding wall portion 124 is used for expanding the ground contact area of the central pattern block 21 of the tire body, enhancing the pattern rigidity of the central pattern block 21 when the tire runs on a hard road at a high speed, improving the traction performance and the controllability of the tire when the tire runs at a high speed, and meeting the requirement of the high-speed running performance of the tire. The profile cross section of the expanded wall portion 124 may have the same cross section as the mating cavity 123 or may have a cross section different from that of the mating cavity 123; the contour surface of the expanded wall portion 124 may surround and seal the tire center block 21, or may partially form a notch without surrounding and sealing the tire body center block 21.
The thickness b of the cross section of the expanding wall part 124 of the central connecting part 121 is more than or equal to 3.0mm, so that the rigidity of the tire central pattern block 21 can be effectively increased when the expanding wall part is in embedded fit with the central area of the tire tread, and the abrasion performance and the comfort performance of the tire when the tire runs on a hard road surface at a high speed are ensured.
In the schematic diagram of the planar unfolding structure of the tread rubber ring of the second embodiment of the invention shown in fig. 5, the circumferential spaces 14 are formed between the central connecting portions 121, and when the central pattern blocks 21 of the tire body and the central connecting portions 121 of the tread rubber ring 1 are nested and matched to form a tire assembly, the circumferential spaces 14 of the tread rubber ring 1 form transverse grooves of the tire, so that the pattern rigidity of the central region of the tire is increased, the ground contact area of the tire is increased, the tire abrasion performance is ensured, the traction performance and the handling performance of the tire during running on a hard road surface are improved, and the high-speed running performance of the tire is met.
