Description

Technical Field

[0001] The utility model relates to the technical field of vehicle tires, in particular to an anti-skid, wear-resistant and super-manipulation type off-road mountain tire. Background Art

[0002] The off-road vehicles face different environments and road surfaces, so the emphasis on off-road tires is also different. Off-road tires refer to tires suitable for driving in the wild, which usually include road tires, all-terrain tires, mud tires, etc. However, ordinary off-road tires have the following disadvantages: 1. Limited use environment, cannot adapt to most non-paved roads; 2. Poor handling performance in gravel, mud, rock slopes and other environments; 3. Off-road mountain tires with good anti-skid performance have more patterns and average wear resistance; while tires with good wear resistance have fewer patterns and average anti-skid performance;

[0003] In combination with the above, when used in off-road scenarios, the driving of tires on gravel, mud, rocky slopes and other outdoor places belongs to friction driving, and the tire tread grooves directly affect the mutual friction conditions and energy consumption in scenes such as gravel, mud, rocky slopes, etc., and the ground contact pressure and ground contact area of ​​the tire determine the depth of tire sinking and the level of rolling resistance. In the prior art, the tire tread grooves are single or only designed with a symmetrical structure, which cannot adapt to use in multiple terrain scenarios. In view of the above technical defects, a solution is now proposed. Utility Model Content

[0004] The utility model aims to provide a non-slip, wear-resistant and super-controllable off-road mountain tire to solve the problem that the tire has a single tread groove or is only designed with a symmetrical structure, which makes it unable to adapt to long-term use in multiple terrain scenes.

[0005] The purpose of the utility model can be achieved through the following technical solutions: a non-slip, wear-resistant and super-controllable off-road mountain tire, including a carcass, wherein the outer end of one side of the tread of the carcass is provided with an outer flat block and an outer square block, and the outer end of the other side of the carcass tread is provided with an inner flat block and an inner stripe block, and the middle part of the carcass tread is sequentially provided with staggered middle flat blocks and middle square blocks; the gaps between adjacent middle flat blocks and middle square blocks are provided with dislocation blocks one and two connected to the carcass tread; the gaps between adjacent outer flat blocks and outer square blocks are provided with elastic rubber strips connected to the carcass tread, and the middle parts of the upper surfaces of the outer flat blocks, middle flat blocks, outer square blocks and middle square blocks are all provided with knife grooves.

[0006] Preferably, shoulders on both sides of the tire body are provided with shoulder portions, and the tire body is provided with a shoulder pattern block group through the surface of the shoulder portion, and the shoulder pattern block group includes shoulder pattern block 1 and shoulder pattern block 2 that are staggered, and a shoulder pattern groove is formed between shoulder pattern block 1 and shoulder pattern block 2.

[0007] Preferably, both circumferential side edges of the shoulder block 1 and the shoulder block 2 are stepped structures, and the outer end faces are formed by overlapping the upper end face and the lower end face.

[0008] Preferably, each of the elastic rubber strips is provided with spaced straight grooves, and the thickness of the elastic rubber strip is lower than the thickness of the outer flat pattern block and the outer square pattern block.

[0009] Preferably, the knife groove comprises a “V”-shaped structure and a “︽”-shaped structure, the knife grooves of the “V”-shaped structure and the “︽”-shaped structure are staggered and spaced apart, and a continuous S-shaped groove is longitudinally opened on the knife groove.

[0010] Preferably, the first dislocation block and the second dislocation block are staggered and spaced apart in the gaps between adjacent middle flat grain blocks and middle square grain blocks.

[0011] Beneficial effects of the utility model:

[0012] (1) The utility model combines the pattern block groups staggered and circumferentially spaced on the tire with the pattern groove groups formed by each pattern block group, and the "arch bridge type" pattern groove group and the "S type" pattern groove group and the "non-directional block" pattern block group, the "arrow-shaped" pattern block group, the "knife tip" pattern block group and the "strip" pattern block group together form a tire ground contact footprint structure, and the pattern block groups of different heights form a high and low missing edge, so as to play a buffering role when the tire is running on an unpaved road and improve the grip performance; each pattern groove group has a different inclination angle and a staggered arrangement, so that the formed pattern blocks are diversified, and the air noise generated by each groove and pattern block group when the tire rolls on the ground is inconsistent, thereby reducing the resonance phenomenon and thus reducing the noise; in addition, the boundaries of each pattern groove group and the pattern block groups formed in different positions and shapes will generate different stresses, which provide diversified grip, ride comfort and handling stability when driving on gravel, mud, rock slopes and the like;

[0013] (2) Each tread groove group is provided with elastic strips of different shapes, sizes, lengths, directions, angles and positions. When the tire rolls and contacts the ground, the cutting force of each boundary on the gravel, mud, rock slope and other road surfaces is multi-directional and diverse. Gravel and mud will adhere to the tread groove group and wrap around it to form a smooth circle, so that the car is stuck in the gravel and mud and cannot move. The elastic strip generates a rebound force due to the rolling ground force of the tire, which will discharge the gravel and mud adhered to the tread groove group in time, thereby improving the grip and stability.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1: This embodiment is used to solve the problem that the tire tread groove is single or only designed with a symmetrical structure, which makes it unable to adapt to long-term use in multiple terrain scenarios.

[0025] See also Figure 1 - Figure 7As shown, this embodiment is a non-slip wear-resistant super-controllable off-road mountain tire, comprising a carcass 1, an outer flat block 2 and an outer square block 6 are provided at the outer end of one side of the tread of the carcass 1, an inner flat block 4 and an inner stripe block 5 are provided at the outer end of the other side of the tread of the carcass 1, and the middle part of the tread of the carcass 1 is sequentially provided with staggered middle flat blocks 3 and middle square blocks 7; the gaps between adjacent middle flat blocks 3 and middle square blocks 7 are provided with dislocation blocks 1 8 and dislocation blocks 2 9 connected to the tread of the carcass 1; the gaps between adjacent outer flat blocks 2 and outer square blocks 6 are provided with elastic rubber strips 10 connected to the tread of the carcass 1, and the middle parts of the upper surfaces of the outer flat blocks 2, the middle flat blocks 3, the outer square blocks 6 and the middle square blocks 7 are all provided with knife grooves 11;

[0026] The gap between the outer flat block 2 and the outer square block 6 constitutes the first groove, and the opening angle of the first groove is 5°-10°. The gap between the middle flat block 3 and the middle square block 7 constitutes the second groove, and the opening angle of the second groove is 6°-10°. The gap between the inner flat block 4 and the inner stripe block 5 constitutes the third groove, and the opening angle of the third groove is 6°-10°. The groove groups with different shapes, positions and boundaries realize the diversified design of the tread composition structure, thereby preventing the problem that the tire groove is single or only symmetrically designed, which cannot be used in multiple terrain scenes;

[0027] Since the cutting force of each boundary on the road surface such as gravel, mud, rock slope is multi-directional and diverse, gravel and mud will adhere to the groove group and wrap it to form a smooth circle, so that the car is stuck in the gravel and mud and cannot move: In this scheme, each groove group is provided with elastic strips of different shapes, sizes, lengths, directions, angles and positions. When the tire rolls and touches the ground, the elastic strips generate rebound force due to the rolling ground force of the tire, which will discharge the gravel and mud adhered to the groove group in time, thereby improving the grip and stability;

[0028] Each elastic rubber strip 10 is provided with spaced straight grooves 16, and the thickness of the elastic rubber strip 10 is lower than the thickness of the outer flat pattern block 2 and the outer square pattern block 6;

[0029] The knife groove 11 includes a "V"-shaped structure and a "︽"-shaped structure, and the knife grooves 11 of the "V"-shaped structure and the "︽"-shaped structure are staggered and spaced apart, and a continuous S-shaped groove 15 is longitudinally opened on the knife groove 11;

[0030] The dislocation blocks 1 8 and the dislocation blocks 2 9 are staggered and arranged in the gaps between the adjacent middle flat grain blocks 3 and the middle middle grain blocks 7;

[0031] See also Figure 1 - Figure 7As shown, by combining the pattern block groups staggered and circumferentially spaced on the tire with the pattern groove groups formed by each pattern block group, the "arch bridge type" pattern groove group and the "S type" pattern groove group and the "non-directional block" pattern block group, the "arrow-shaped" pattern block group, the "knife tip" pattern block group and the "strip-shaped" pattern block group together constitute the tire's ground contact footprint structure, and the pattern block groups of different heights constitute a high and a low edge, so as to play a buffering role when the tire runs on an unpaved road and improve the grip performance; each pattern groove group has a different inclination angle and a staggered arrangement, so that the formed pattern blocks are diversified, and the air noise generated by each groove and pattern block group when the tire rolls on the ground is inconsistent, thereby reducing the resonance phenomenon and thus reducing the noise; in addition, the boundaries of each pattern groove group and the pattern block groups formed in different positions and shapes will produce different stresses, which provide diversified grip, ride comfort and handling stability when driving on gravel, mud, rock slopes and the like.

[0032] Embodiment 2: This embodiment is used to solve the problem that the shoulder of the tire is prone to vertical impact and thus tire blowout when crossing a mountain road.

[0033] See also Figure 1 - Figure 4 As shown, a non-slip wear-resistant super-controllable off-road mountain tire of this embodiment includes shoulder portions 14 provided on the shoulders of both sides of a carcass 1, a shoulder pattern block group is provided on the surface of the carcass 1 through the shoulder portion 14, the shoulder pattern block group includes staggered shoulder pattern blocks 12 and shoulder pattern blocks 2 13, and shoulder pattern grooves are formed between the shoulder pattern blocks 12 and the shoulder pattern blocks 2 13, the circumferential sides of the shoulder pattern blocks 12 and the shoulder pattern blocks 2 13 are stepped structures, and the outer end faces are formed by overlapping the upper end face and the lower end face;

[0034] See also Figure 1 - Figure 4 As shown, the lower part of the shoulder portion 14 adopts a "collision wall" structure design, that is, irregular geometric convexities are arranged in the sidewall area below the shoulder portion 14 and above the horizontal axis, and are arranged in three heights, and the height is 3-5mm of the convex surface of the sidewall, so as to prevent sharp objects on mountainous roads from puncturing the sidewall, thereby protecting the tire;

[0035] In combination with the first embodiment and the second embodiment, the groove groups formed by the staggered and circumferentially spaced pattern block groups on the tire and the pattern block groups can be combined to form the tire's ground contact footprint structure with the "arch bridge type" pattern groove group and the "S type" pattern groove group and the "non-directional block" pattern block group, the "arrow-shaped" pattern block group, the "knife tip" pattern block group and the "strip-shaped" pattern block group, and the pattern block groups of different heights form a high and a low edge, so as to play a buffering role and improve the grip performance when the tire is running on an unpaved road; and the pattern groove groups with different inclination angles and staggered arrangement can be used. The two are used in combination to effectively form the tread through the novel structure of the block group and the groove group. The block groups and groove groups with different boundaries, positions and shapes will produce different stresses, which makes the tire provide diversified grip when driving on gravel, mud, rock slopes and other places. Combined with the effective sidewall anti-collision structure design, the driving stability of the tire on unpaved roads is improved, and the wear resistance and anti-skid effect of the tire are improved.
