Description

Technical Field

[0001] The utility model relates to the technical field of automobile tires, in particular to a porous studded winter automobile tire. Background Art

[0002] In cold regions with perennial icing, especially in the northern cold regions of China, northern Europe, North America and northern Japan, when the tire travels on the ground, due to the reduced friction between the tire and the road surface caused by wetness and slipperiness, skidding occurs, which is likely to lead to traffic accidents and endanger personal safety. Therefore, anti-skid winter tires have emerged as the times require.

[0003] At present, the common anti-skid tires are mainly divided into two types: studded tires with stud holes and tires with anti-skid chains. The studded tires are easy to install, do not need to be frequently installed and disassembled, have good maneuverability and stability; they can effectively prevent skidding between the tire and the road surface, and have higher practicality, so they are needed by the market.

[0004] Since some countries have stipulated the usage time, regions and installation quantity of studded tires, this has greatly increased the installation times and replacement costs of the tires. At present, it is stipulated that the number of studs on the rolling circumference per meter of studded tires does not exceed 50 stud holes. Therefore, the contact between the studs and the ground is relatively concentrated and the stability is poor. To meet the market demand, the present utility model is proposed. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a porous studded winter automobile tire that can overcome or at least partially solve the above problems.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A porous studded winter automobile tire includes a tire body, and further includes: a plurality of transverse grooves and circumferential main grooves are respectively formed on the tire body, and the circumferential main grooves and the transverse grooves intersect to form a plurality of independent tread blocks; stud holes are formed in the tread blocks, and high-strength alloy studs can be embedded in the stud holes; V-shaped patterns are evenly distributed on the tread blocks; a tread crown is provided on the tire body, and the stud holes are symmetrically distributed on both sides of the tread crown.

[0008] Preferably, a circular ring is fixed outside the stud hole, and the circular ring is lower than the reference plane of the tire body.

[0009] Further, a decorative line is provided inside the circular ring.

[0010] Further, a star-shaped transition surface is provided between the circular ring and the stud hole, and the star-shaped transition surface is at the same height as the reference plane of the tire body.

[0011] Preferably, shoulder ribs and tread ribs are provided on both sides of the tire body, and the shoulder ribs and the tread ribs jointly form a V-shaped pattern.

[0012] Preferably, the circumferential width of the tread block is 15 mm - 35 mm.

[0013] Preferably, the width of the transverse groove is 4 mm - 7 mm, and the width of the circumferential main groove is 5 mm - 9 mm.

[0014] Compared with the prior art, the present utility model provides a porous studded winter car tire, which has the following beneficial effects:

[0015] 1. For this porous studded winter car tire, by arranging the stud holes symmetrically on both sides of the crown and arranging them in a non-linear sequence in the circumferential direction of the crown, it can ensure that there are always studs in contact with the road surface when the tire body rotates without increasing the number of stud holes, thus avoiding the phenomenon that the studs have contact gaps with the road surface when the vehicle is slowly climbing the slope, resulting in tire slippage.

[0016] 2. For this porous studded winter car tire, by evenly arranging V-shaped patterns on the tread blocks, it can well ensure the grip between the tire and the ice and snow road surfaces, while taking into account a series of performances such as wear, rolling resistance, and comfort.

[0017] For the parts not involved in this device, they are the same as or can be implemented by the prior art. The present utility model can ensure that there are always studs in contact with the road surface when the tire body rotates without increasing the number of stud holes, avoiding the phenomenon that the studs have contact gaps with the road surface when the vehicle is slowly climbing the slope, resulting in tire slippage, and at the same time taking into account a series of performances such as wear, rolling resistance, and comfort.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0025] Embodiment 1:

[0026] Referring to Figures 1 - 4 , a porous studded winter car tire, including a tire body 1, further including: a plurality of transverse grooves 2 and circumferential main grooves 4 are respectively formed on the tire body 1, and the circumferential main grooves 4 and the transverse grooves 2 intersect to form a plurality of independent pattern blocks 12; stud holes 8 are formed on the pattern blocks 12, and high-strength alloy studs can be embedded in the stud holes 8; V-shaped patterns 11 are uniformly distributed on the pattern blocks 12; a tread crown 3 is provided on the tire body 1, the stud holes 8 are symmetrically distributed on both sides of the tread crown 3, a ring 7 is fixed outside the stud holes 8, the ring 7 is lower than the reference surface of the tire body 1, a decorative line 9 is provided inside the ring 7, a star-shaped transition surface 10 is provided between the ring 7 and the stud holes 8, the star-shaped transition surface 10 has the same height as the reference surface of the tire body 1, shoulder ribs 5 and pattern ribs 6 are provided on both sides of the tire body 1, the shoulder ribs 5 and the pattern ribs 6 together form a V-shaped pattern, the circumferential width of the pattern block 12 is 15 mm - 35 mm, the width of the transverse groove 2 is 4 mm - 7 mm, and the width of the circumferential main groove 4 is 5 mm - 9 mm.

[0027] In the present invention, the tread of the tire body 1 is a symmetric pattern, and the V-shaped patterns 11 are uniformly distributed on the pattern blocks 12, so that the grip between the tire and the ice and snow road surface can be well ensured, and at the same time, a series of performances such as wear resistance, rolling resistance, and comfort are taken into account;

[0028] There are at most two symmetric stud holes 8 on each pitch, and corresponding anti-slip high-strength alloy studs can be installed. Thus, the high-strength alloy studs can be driven into the ice and snow to increase the grip of the tire body 1. The stud holes 8 are symmetrically distributed on both sides of the tread crown 3 and arranged circumferentially on the tread crown 3 in a non-linear sequence. Therefore, without increasing the number of stud holes 8, it can be ensured that there is always a stud in contact with the road surface when the tire body 1 rotates, avoiding the phenomenon of tire slippage caused by the contact gap between the studs and the road surface when the vehicle is slowly climbing a slope;

[0029] The shoulder ribs 5 and the tread ribs 6 together form a V-shaped pattern. When the vehicle is driving on a large amount of snow and sunken ice surfaces, the shoulder can also generate friction with the frozen wall on the side through the V-shaped pattern;

[0030] While limiting the stud holes 8, the ring 7 also plays a role in stabilizing and strengthening the structure of the stud holes 8. Thus, it can better ensure the tight connection between the high-strength alloy studs and the stud holes 8, avoiding the phenomenon that the stud holes 8 are deformed under the influence of external forces, resulting in the detachment of the high-strength alloy studs. The ring 7 is lower than the reference plane of the tread surface, so as to avoid damage caused by the contact between the ring 7 and the road surface;

[0031] During installation, the stud holes 8 can ensure that the stud body of the high-strength alloy stud is below the radial outer surface of the tire body 1, and the core part protrudes from the radial outer surface of the tire body 1. Therefore, even if there are many high-strength alloy studs installed on the tire body 1, it will not cause great damage to the ground.

[0032] The above is only the preferred specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
