[0001] This invention relates to the field of tire tread technology, and in particular to a multifunctional motorcycle tire tread pattern. Background Technology

[0002] Tires are the only part of a motorcycle that comes into direct contact with the road surface. Their main functions are to bear loads, transmit the power required for the motorcycle to move, enable the motorcycle to be driven stably, and cope with different road conditions. The tire tread pattern has a significant impact on the motorcycle's power / braking performance, drainage performance, grip performance, driving comfort, and driving safety.

[0015] Wherein, the ratio of the length of the second patterned groove in the circumferential direction to the predetermined circumferential length of the patterned module is 35% to 40%; the second patterned groove includes interconnected second patterned groove a, second patterned groove b, and second patterned groove c; the ratio of the length of the second patterned groove c in the circumferential direction to the length of the second patterned groove in the circumferential direction is 39% to 44%; the ratio of the length of the second patterned groove in the axial direction to the predetermined axial length of the patterned module is 38% to 44%; the ratio of the length of the second patterned groove c in the axial direction to the length of the second patterned groove in the axial direction is 16% to 20%; the ratio of the length of the second patterned groove b in the axial direction to the length of the second patterned groove in the axial direction is 45% to 50%; the angle formed by the second patterned groove a and the equatorial plane is 63° to 70°.

[0016] After adopting the above technical solution, the beneficial effects of the present invention are:

[0017] 1. By setting a first, second, and third tread groove, with the third groove confined to the sidewall tread band; and the second groove confined to the sidewall, second, and third tread bands, a structure is formed where the first tread band in the middle has more tread and the sides have less. This improves the water drainage performance of the first tread band where the motorcycle tire contacts the ground, ensuring optimal drainage. The relatively fewer tread patterns on the second and third tread bands allow the sidewalls of the motorcycle tire to contact the ground more effectively when the motorcycle is cornering, increasing tire grip. The symmetrical tire tread pattern also reduces rolling resistance, decreasing the power required for wheel movement and reducing fuel consumption.

[0018] 2. The first tread belt is divided into a middle tread belt and a side tread belt. The ratio of the area without tread on the middle tread belt to the total area of ​​the middle tread belt is greater than or equal to 98%, thus forming a basically treadless area in the middle tread belt. This achieves full contact area of ​​the motorcycle tire, ensuring maximum grip and maximum traction during normal driving, and maximizing the motorcycle's performance.

[0019] 3. By reasonably adjusting the proportion of the first, second, and third tread belts, the tread pattern ratio of each area is ensured. This ensures that during normal driving, the first tread belt on the first contact surface has good water drainage performance, while the second and third tread belts provide better grip when turning, thus maximizing the motorcycle's performance.

[0020] 4. The first and second patterned grooves form a unidirectional pattern, so that the pattern direction is the same, which enhances the rapid drainage when the central drainage channel passes through the wetland, and the wetland performance is better than that of non-unidirectional drainage.

[0021] 5. The first tread branch groove on the second tread belt adopts a transverse groove, thereby improving the motorcycle tire's resistance to deformation.

[0022] 6. The depth and width of the first tread branch groove on the second tread belt are less than the depth of the first tread branch groove on the third tread belt, and a first water collection trough is provided at their intersection; the depth and width of the second tread branch groove on the second tread belt are less than the depth of the second tread branch groove on the third tread belt, and a second water collection trough is provided at their intersection; thus, water can be quickly discharged from the second tread belt to the third tread belt, improving drainage performance; in addition, shallow grooves are provided at the ends of the first and second tread branch grooves, and their width gradually decreases from the first or second water collection trough to the corresponding end, which helps to break the water film and improve drainage performance.

[0023] 7. The first and second water collection tanks are equipped with stepped surfaces to form a flood ramp, further increasing the width of the water surface, thereby reducing the impact force of the water flow and ensuring that the water flow has a smaller impact force when exiting the side of the motorcycle tire, preventing splashing; at the same time, it can increase the strength of the connection position and prevent stress concentration and damage caused by the depth difference at this position. In addition, the larger water collection tank is filled to prevent soil and rocks from getting stuck inside, which would hinder drainage and damage the tire.

[0024] 8. By changing the angles of the first, second, and third tread grooves, the inherent frequency of motorcycle tire compression is broken, preventing resonance and reducing noise during driving.

[0025] This invention addresses the technical problem of motorcycle tires failing to simultaneously achieve optimal grip, drainage, stability, and traction, resulting in a poor user experience. The invention addresses this issue by incorporating a first, second, and third tread groove, with the third groove confined to the sidewall tread band. The second tread groove is also positioned on the sidewall, second, and third tread bands. This creates a structure where the first tread band has more tread pattern than the sides, improving drainage at the point of contact with the ground and ensuring optimal water drainage. The relatively fewer tread patterns on the second and third tread bands allow for better grip when the motorcycle is cornering, as the tire's sidewalls are in contact with the ground. The symmetrical tread pattern also reduces rolling resistance, decreasing the power required for wheel movement and reducing fuel consumption. Attached Figure Description

[0030] Figure 5 This is a cross-sectional view of a motorcycle tire. Detailed Implementation

[0031] The invention will now be further described with reference to the accompanying drawings.

[0032] The orientations mentioned in this specification are based on the orientation of the tread pattern of the multifunctional motorcycle tire of the present invention when it is working normally. They do not limit the orientation during storage and transportation, but only represent relative positional relationships, not absolute positional relationships.

[0033] like Figure 5 As shown, a multifunctional motorcycle tire tread pattern is set on the tread belt 8.

[0034] like Figure 1 As shown, the tread belt 8 is divided into a first tread belt 1, a second tread belt 2, and a third tread belt 3 in the transverse direction. The first tread belt 1 is located in the middle of the tread belt 8. There are two second tread belts 2, symmetrically arranged on both sides of the first tread belt 1. There are two third tread belts 3, arranged on the outer sides of the second tread belt 2. The first tread belt 1 can be further divided into a middle tread belt 11 and side tread belts 12 located on both sides of the middle tread belt 11. The first tread belt 1 accounts for 35% to 40% of the axial width of the entire tread belt 8; the third tread belt 3 accounts for 20% to 25% of the axial width of the entire tread belt 8; and the middle tread belt 11 accounts for 20% to 25% of the axial width of the first tread belt 1.

[0035] The tread pattern 4 includes a pattern module T that is replicated along the circumferential direction of the tread band 8 and has a predetermined circumferential length. The pattern module T includes a left pattern module and a right pattern module that are symmetrical about the equatorial plane XX of the tire. By setting the left and right symmetrical pattern modules, the rolling resistance of the motorcycle tire is reduced, which reduces the power required for the wheel to move forward and reduces fuel consumption.

[0036] The left and right pattern modules have the same structure, only symmetrical from left to right. Therefore, the following detailed explanation will only take the right pattern module as an example.

[0037] The right pattern module includes a first pattern groove 41, a second pattern groove 42, and a third pattern groove 43.

[0038] like Figure 1 and Figure 2 As shown, the first tread groove 41 includes a plurality of interconnected first tread branch grooves 411, which are positioned on the side tread belt 12, the second tread belt 2 and the third tread belt 3.

[0039] The ratio of the length 41Z of the first pattern groove 41 in the circumferential direction to the predetermined circumferential length J of the pattern module T is 48% to 53%. In this embodiment, seven first pattern branch grooves 411 are provided, namely, first pattern branch grooves 411a, 411b, 411c, 411d, 411e, 411f, and 411g.

[0040] First tread branch grooves 411c, 411d, and 411e are defined in the side tread zone 12 region, and first tread branch grooves 411a and 411g are defined in the third tread zone 3 region. The ratio of the length 411CZ of the first tread branch groove 411c in the circumferential direction to the length 41Z of the first tread groove 41 in the circumferential direction is 10% to 15%; the ratio of the length 411dz of the first tread branch groove 411d in the circumferential direction to the length 41Z of the first tread groove 411e in the circumferential direction to the length 41Z of the first tread groove 411e in the circumferential direction is 33% to 38%; and the ratio of the length 411ez of the first tread branch groove 411e in the circumferential direction to the length 41Z of the first tread groove 41 in the circumferential direction is 15% to 20%. The ratio of the length 411h of the first pattern groove 41 in the axial direction to the predetermined axial length WT of the pattern module T is 39% to 43%; the ratio of the length 411ch of the first pattern branch groove 411c in the axial direction to the length 411h of the first pattern groove 41 in the axial direction is 22% to 27%; the ratio of the length 411bh of the first pattern branch groove 411b in the axial direction to the length 411h of the first pattern groove 41 in the axial direction is 30% to 35%; the ratio of the length 411bh of the first pattern branch groove 411b to the length 411h of the first pattern groove 41 in the axial direction is 30% to 35%; the ratio of the length 411e of the first pattern branch groove 41 in the axial direction to the length WT of the first pattern module T is 39% to 43%; the ratio of the length 411h of the first pattern branch groove 411c in the axial direction to the length WT of the first pattern module T is 22% to 27%; the ratio of the length 411bh of the first pattern branch groove 411b in the axial direction to the length WT of the first pattern groove 41 in the axial direction is 30% to 35%; the ratio of the length 411bh of the first pattern branch groove 411b in the axial direction to the length WT of the first pattern module T is 39% to 43%; the ratio of the length 411ch of the first pattern branch groove 411c in the axial direction to the length WT of the first pattern module T is 39% to 43%; the ratio of the length 411h of the first pattern branch groove 411b in the axial direction to the length WT of the first pattern module T is 39% to 43 The ratio of the length 411eh in the axial direction to the length 411h of the first pattern groove 41 in the axial direction is 13% to 17%; the ratio of the length 411fh of the first pattern branch groove 411f in the axial direction to the length 411h of the first pattern groove 411 in the axial direction is 37% to 42%; the angle 411ajd formed by the first pattern branch groove 411a and the equatorial plane XX is 33° to 38°; the angle 411gjd formed by the first pattern branch groove 411g and the equatorial plane is 43° to 48°.

[0041] The first tread branch grooves 411b and 411f located on the second tread band 2 are transverse grooves, meaning their extension is essentially horizontal. Transverse grooves offer better resistance to deformation than longitudinal grooves, thus improving the motorcycle tire's resistance to deformation during sharp turns.

[0042] The ends of the first tread branch grooves 411a and 411g on the third tread belt 3 are provided with a first shallow groove 413. The width of the first tread branch grooves 411a and 411g gradually decreases from the front end to the end. By providing the first shallow groove 413 and the contracted first tread branch grooves 411a and 411g, it is beneficial to puncture the water film and drain the water.

[0043] The depth and width of the first tread branch groove 411b on the second tread belt 2 are less than the depth and width of the front end of the first tread branch groove 411a on the third tread belt 3, and a first water collection trough 412a is provided at their intersection. The depth and width of the first tread branch groove 411f on the second tread belt 2 are less than the depth and width of the front end of the first tread branch groove 411g on the third tread belt 3, and a first water collection trough 412b is also provided at their intersection. A first shallow groove 413 is provided in the opposite direction to the first tread branch groove 411a or the first tread branch groove 411g. The first shallow groove 413 facilitates the puncture of the water film and facilitates the discharge of water.

[0044] To improve the deformation resistance and grip of motorcycle tires, stepped surfaces are provided at the locations of the first water collection tanks 412a and 412b. The stepped surfaces gradually transition from the first tread branch groove 411b to the first tread branch groove 411a, and from the first tread branch groove 411f to the first tread branch groove 411g, that is, from the shallow position to the deep position, forming a flood slope to further increase the width of the water surface, thereby reducing the impact force of the water flow and ensuring that the impact force of the water flow is small when it exits the side of the motorcycle tire, preventing splashing. At the same time, it can increase the strength of the connection position and prevent stress concentration and damage caused by the depth difference. In addition, the larger positions of the first water collection tanks 412a and 412b are filled to prevent soil and rocks from getting stuck in the first water collection tanks 412a and 412b, which would obstruct drainage and cause damage to the tires.

[0045] like Figure 1 and Figure 3 As shown, the second tread groove 42 includes a plurality of interconnected second tread branch grooves 421, and the second tread groove 42 is positioned on the side tread belt 12, the second tread belt 2 and the third tread belt 3.

[0046] The ratio of the length 42Z of the second pattern groove 42 in the circumferential direction to the predetermined circumferential length J of the pattern module T is 35% to 40%. In this embodiment, three second pattern branch grooves 421 are provided, namely second pattern branch grooves 421a, second pattern branch grooves 421b, and second pattern branch grooves 421c. The ratio of the length 421cz of the second pattern branch groove 421c in the circumferential direction to the length 42z of the second pattern groove 42 in the circumferential direction is 39% to 44%; the ratio of the length 42h of the second pattern groove 42 in the axial direction to the predetermined axial length WT of the pattern module T is 38% to 44%; the ratio of the length 421ch of the second pattern groove 42c in the axial direction to the length 42h of the second pattern groove 42 in the axial direction is 16% to 20%; the ratio of the length 421bh of the second pattern groove 42b in the axial direction to the length 42h of the second pattern groove 42 in the axial direction is 45% to 50%; the angle 421ajd formed by the second pattern groove 42a and the equatorial plane is 63° to 70°.

[0047] The end of the second tread branch groove 421a on the third tread belt 3 is provided with a second shallow groove 423, and the width of the second tread branch groove 421a gradually decreases from the front end to the end. By providing the second shallow groove 423 and the contracted second tread branch groove 421a, it is beneficial to puncture the water film and drain the water.

[0048] The depth and width of the second tread branch groove 421b on the second tread belt 2 are less than the depth and width of the front end of the second tread branch groove 421a on the third tread belt 3, and a second water collection trough 422 is provided at their intersection; a second shallow groove 423 is also provided in the opposite direction to the second tread branch groove 421a in the position of the second water collection trough 422. The second shallow groove 423 is conducive to the puncture of the water film and facilitates the discharge of water.

[0049] In order to improve the deformation resistance and grip of motorcycle tires, a stepped surface is provided at the second water collection tank 422. The stepped surface gradually transitions from the second tread branch groove 421b to the second tread branch groove 421a, and its function and purpose are the same as the stepped surface mentioned above.

[0050] The first tread groove 41 and the second tread groove 42 form a unidirectional tread pattern, and the tread pattern is in the same direction. This enhances the ability of the tire tread pattern of the first tread band 1 to drain water quickly when driving through wet areas, resulting in better wet performance than non-unidirectional tires.

[0051] like Figure 1 and Figure 4 As shown, the third tread groove 43 includes a plurality of interconnected third tread branch grooves 431, and the third tread groove 43 is defined on the side tread belt 12.

[0052] The ratio of the length 43z of the third pattern groove 43 in the circumferential direction to the predetermined circumferential length J of the pattern module T is 28% to 33%. In this embodiment, three third pattern branch grooves 431 are provided, namely third pattern branch grooves 431a, third pattern branch grooves 431b and third pattern branch grooves 431c. The ratio of the length 431cz of the third pattern branch groove 431c in the circumferential direction to the length 43z of the third pattern groove 43 in the circumferential direction is 38% to 44%; the ratio of the length 431az of the third pattern branch groove 431a in the circumferential direction to the length 43z of the third pattern groove 43 in the circumferential direction is 42% to 47%; the ratio of the length 43h of the third pattern groove 43 in the axial direction to the predetermined axial length WT of the pattern module T is 13% to 18%; the ratio of the length 431ch of the third pattern branch groove 431c in the axial direction to the length 43h of the third pattern groove 43 in the axial direction is 34% to 39%; the angle 431ajd formed by the third pattern branch groove 431a and the equatorial plane is 36° to 40°.

[0053] like Figure 1 As shown, the ratio of the area of ​​the treadless area of ​​the intermediate tread belt 11 to the area of ​​the entire intermediate tread belt 11 is greater than or equal to 98%, thus forming a basically treadless area in the intermediate tread belt. This achieves full contact area of ​​the motorcycle tire, ensuring maximum grip and maximum traction during normal driving, and maximizing the motorcycle's performance.

[0054] The curvature ratio of the motorcycle tire is less than 0.35, and the land ratio is above 80% and below 90%.

[0055] This invention addresses the technical problem of motorcycle tires failing to simultaneously achieve optimal grip, drainage, stability, and traction, resulting in a poor user experience. The invention addresses this issue by incorporating a first, second, and third tread groove, with the third groove confined to the sidewall tread band. The second tread groove is also positioned on the sidewall, second, and third tread bands. This creates a structure where the first tread band has more tread pattern than the sides, improving drainage at the point of contact with the ground and ensuring optimal water drainage. The relatively fewer tread patterns on the second and third tread bands allow for better grip when the motorcycle is cornering, as the tire's sidewalls are in contact with the ground. The symmetrical tread pattern also reduces rolling resistance, decreasing the power required for wheel movement and reducing fuel consumption.

[0056] Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.
