Description

Technical Field

[0001] This utility model belongs to the field of tire design technology and relates to a readable tire tread structure with a built-in depth scale on an all-steel radial tread. Background Technology

[0002] Tires are annular, elastic rubber products mounted on various vehicles or machinery for contact with the ground and rolling. Typically mounted on metal rims, tires support the vehicle body, cushion external impacts, ensure contact with the road surface, and guarantee vehicle performance. Tires are often used under complex and harsh conditions, enduring various deformations, loads, forces, and extreme temperatures during operation. Therefore, they must possess high load-bearing capacity, traction, and cushioning performance. Simultaneously, tires also require high wear resistance and flexural strength, as well as low rolling resistance and heat generation. Half of the world's rubber consumption is used in tire production, highlighting the significant rubber consumption involved in tire manufacturing.

[0003] Tire tread designs come in a variety of styles, tailored to different uses and road conditions. These factors should be considered when selecting tires. Tire tread plays a crucial role in overall driving performance. A well-designed tread pattern can not only effectively save fuel and reduce noise during driving, but also enhance the vehicle's driving force, braking force, and traction on various harsh and slippery road surfaces, thereby improving driving safety.

[0004] There are several main types of tire tread patterns:

[0005] (1) Straight groove pattern, also called ordinary pattern, is a pattern design with vertical grooves as the main feature;

[0006] Features include excellent handling stability, low rotational resistance, low noise, and especially excellent drainage performance, making it less prone to lateral slippage.

[0007] Suitable for walking on flat surfaces;

[0008] Vehicle types used: cars, trucks, and even airplanes;

[0009] Disadvantages: Poor driving and traction;

[0010] (2) Horizontal groove pattern, a pattern design with horizontal grooves as the main feature;

[0011] Features: The horizontal groove pattern provides excellent driving force, braking force and traction, and its wear resistance is also excellent.

[0012] Suitable for rough road surfaces such as gravel roads;

[0013] The vehicles used are mostly industrial and short-to-medium distance vehicles, such as bulldozers, excavators, loaders and other medium and heavy-duty vehicles;

[0014] Disadvantages: High noise level;

[0015] (3) Vertical and horizontal groove pattern, also called composite pattern, which combines the design of vertical groove and horizontal groove patterns;

[0016] Features: It combines the advantages of both longitudinal and transverse groove patterns;

[0017] Suitable for rough road surfaces;

[0018] Disadvantages: It is prone to abnormal wear;

[0019] (4) Block pattern, the pattern is arranged in regular blocks;

[0020] Features include good driving and braking force, providing the power to propel the vehicle forward;

[0021] Suitable for snow, mud, and other uneven surfaces;

[0022] Disadvantages include poor wear resistance and short service life.

[0023] The main driving routes for light-duty and heavy-duty radial tires on the market are paved roads and above. The main quality defects of tires are shoulder gaps, crown gaps, and poor wear resistance. Tires have high requirements for tread patterns and should have low heat generation, good wear resistance, low noise, and low rolling resistance.

[0024] Patent CN222157109U discloses a tread pattern structure for an all-steel tubeless radial truck tire, including a tire tread and lateral and longitudinal patterns on the tread. The tire tread is composed of ten equal movable sections, with three zigzag grooves. The bottoms of the three grooves and the varying angles of the groove bottoms and surfaces on both sides form variable-angle groove walls. The central groove wall adopts a stepped design. The tread uses hexagonal tread blocks, each with alternating lateral and longitudinal shallow grooves. The groove bottoms feature a full-circular transition design, and thermometer-like shoulder grooves are distributed on the tire shoulder to improve heat dissipation and provide a functional warning, preventing problems caused by shoulder overheating. However, the lateral grooves in this patent are shallow, resulting in generally weak driving force during driving, and it is typically used in tow truck positions. Furthermore, this patent makes it difficult to quickly read tire wear conditions.

[0025] Patent CN222179118U discloses a tread pattern structure for an all-steel tubeless radial truck tire, including a tire tread and lateral and longitudinal patterns on the tread. The tire tread is composed of ten equal movable sections, with four straight grooves, four S-shaped groove bottoms, and three tread blocks. Each tread block has a design of alternating shallow, streamlined lateral and longitudinal grooves, with a fully circular transition design at the groove bottom. A thermometer-like shoulder groove is distributed on the tire shoulder to improve heat dissipation and provide a functional warning, preventing problems caused by shoulder overheating. However, the main grooves in this patent are straight, and the lateral grooves are shallow, resulting in poor driving force during driving, and it is generally used for towing wheel positions. Furthermore, this patent also makes it difficult to quickly read tire wear conditions. Utility Model Content

[0026] The purpose of this invention is to overcome at least one of the defects of the prior art and provide a readable tire tread structure with a built-in depth scale on an all-steel radial track. This invention allows users to read the remaining tread depth of tires on a vehicle without tools, enabling them to quickly and easily identify tire wear and providing good driving performance.

[0027] The objective of this utility model can be achieved through the following technical solutions:

[0028] One of the technical solutions of this utility model is to provide a readable tire tread structure with a built-in depth scale on an all-steel radial tread. The tire body includes a wheel disc and a tire tread. The tire tread is evenly distributed with tread patterns. Along the center line of the tire tread circumferential direction to both sides, three longitudinal tread grooves with the same zigzag direction are evenly distributed. Each longitudinal tread groove includes a groove wall and a groove bottom with the same zigzag direction. A stepped depth scale is provided on the groove wall. Tread blocks are distributed longitudinally between the longitudinal tread grooves. Straight, inclined transverse tread grooves are distributed between the tread blocks. The transverse tread grooves include deep transverse tread grooves and shallow transverse tread grooves, providing strong driving performance.

[0029] Furthermore, the patterned block is pentagonal in shape, with deep and shallow transverse patterned grooves of opposite inclination angles distributed alternately. One end of each deep and shallow transverse patterned groove extends from the protruding bend of two adjacent longitudinal patterned grooves. The bottom and wall of the transverse patterned grooves are transitioned by a full circular arc, providing strong driving performance while preventing groove cracking.

[0030] Furthermore, the depth of the transverse pattern deep groove is 7-9 mm and the width is 3.5-4.5 mm, the depth of the transverse pattern shallow groove is 2.5-3.5 mm and the width is 0.5-1.5 mm, and the absolute value of the inclination angle of the transverse pattern groove is 20-30°.

[0031] Furthermore, the longitudinal patterned groove and the bottom of the longitudinal patterned groove have the same bend position but different bend angles, and the bottom of the longitudinal patterned groove and the wall of the longitudinal patterned groove adopt a full circular arc transition.

[0032] Furthermore, the depth of the longitudinal patterned groove is 15.5-19.5 mm, the width is 14-18 mm, the tortuosity is 55-75°, and the tortuosity of the bottom of the longitudinal patterned groove is 65-85°.

[0033] Furthermore, a set of rectangular stepped depth gauges are set on the wall of the longitudinal groove in the middle. Each set of depth gauges is evenly distributed around the tire tread. By observing the distance between the tire tread and the depth gauges, the tire wear condition can be read.

[0034] Furthermore, each depth gauge has a width of 1.5-2.5mm and a thickness of 0.5-1.5mm. The distance between the top of the highest depth gauge and the tire tread is 1.5-2.5mm, and the difference in distance between the top of adjacent depth gauges and the tire tread is 1.5-2.5mm, thus serving as a gauge.

[0035] Furthermore, the shoulder of the tire tread is evenly distributed with shoulder patterns.

[0036] Furthermore, thermometer-shaped shoulder flowers are evenly distributed on both shoulders of the tire tread.

[0037] Furthermore, the depth of the strip-shaped area of ​​the shoulder flower is 0.5-1.5mm and the width is 1.5-2.5mm, while the depth of the circular area is 1.5-2.5mm and the diameter is 9-11mm.

[0038] As a preferred technical solution, the tire tread is composed of ten equal movable molds, and the tread pattern pitch is 48 segments. The 48 tread segments are evenly distributed in the direction from the ten equal movable molds to the upper and lower side plates.

[0039] Compared with the prior art, the present invention has the following beneficial effects:

[0040] (1) The tire provided by this utility model has a readable tread depth design with a built-in depth scale on the longitudinal tread groove wall, which can read the remaining tread depth of the tire on the vehicle without the aid of professional tools. It can identify the tire wear at any time and quickly, which is more conducive to safe driving and plays a quick guiding role in safe driving and good driving habits during driving.

[0041] (2) The tire provided by this utility model has strong driving performance and higher wear resistance, optimizes the ground contact mark, reduces abnormal wear, ensures no uneven wear and no deformed wear, ensures uniform wear and wear surface, and can effectively reduce the probability of early tire damage caused by shoulder gaps, crown gaps, etc.

[0042] (3) This utility model achieves good guidance, drainage, grip and anti-skid performance of the tire at high speed through the combination design of longitudinal and transverse tread grooves, and also has low rolling resistance, noise and lower failure rate.

[0043] (4) The tire tread provided by this utility model has a shoulder pattern in the form of a thermometer as a heat dissipation groove, which improves the heat dissipation of the shoulder and has a functional warning function to avoid the symptoms caused by the shoulder overheating problem. This structure is conducive to releasing the heat generated by the stress change of the shoulder during driving. At the same time, the shallow depth provides better shoulder rigidity, making the tire life longer. Attached Figure Description
