A new type of EV new energy tire

Abstract

This utility model discloses a novel EV new energy tire, relating to the technical field of tires. It includes a tire crown and tire shoulders, with the tire shoulders comprising a left shoulder and a right shoulder, respectively located on opposite sides of the tire crown. The tire surface is symmetrically provided with longitudinal grooves (first type), a second longitudinal groove is provided between the left shoulder and the tire crown, and a third longitudinal groove is provided between the right shoulder and the tire crown. This utility model employs a wedge-shaped tread groove design (such as a slightly oblique long strip wide transverse groove, a slightly oblique short strip fine groove, and a slightly oblique long strip wide groove, all grooves having a wedge-shaped cross-section), effectively enhancing the overall rigidity of the tread blocks. This structure results in less deformation of the tread blocks during tire operation, especially during acceleration, braking, and steering, enabling more stable transmission of driving and braking forces, significantly improving vehicle handling response speed and driving stability, and meeting the higher demands for tire handling performance brought about by the power characteristics of new energy vehicles.

Description

Technical Field

[0001] This utility model relates to the technical field of tires, and in particular to a novel EV new energy tire. Background Technology

[0002] As living standards continue to improve in China, people have new demands for quality of life, especially for new energy tires. With the rapid development of new energy vehicles, their high load-bearing and high-torque characteristics place higher demands on tire performance, and traditional tires are gradually showing their technological shortcomings.

[0003] Insufficient rigidity of the patterned blocks: Traditional grooves are mostly rectangular or trapezoidal in cross-section, which are prone to deformation under high loads, resulting in unstable transmission of driving force and braking force, affecting handling response and driving stability.

[0004] Limitations of noise control: The regular arrangement of tread pitch can easily cause resonance noise, and tire noise is more prominent in new energy vehicles because there is no engine noise to mask it; the open structure of the tire shoulder also exacerbates noise transmission.

[0005] Insufficient optimization of tire shoulder structure: The rigidity of the tire shoulder tread blocks and the noise insulation capability are not balanced, making it difficult to meet the needs of new energy vehicles.

[0006] To address these issues, this invention utilizes a full wedge-shaped groove design, variable pitch arrangement, and a semi-closed shoulder structure to specifically solve the aforementioned problems and meet the stringent performance requirements of EV vehicles. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution: a novel EV new energy tire, comprising a tire crown and a tire shoulder, wherein the tire shoulder comprises a left tire shoulder and a right tire shoulder, the left tire shoulder and the right tire shoulder are respectively disposed on both sides of the tire crown, a longitudinal groove I is symmetrically disposed on the tire surface, a longitudinal groove II is disposed between the left tire shoulder and the tire crown, and a longitudinal groove III is disposed between the right tire shoulder and the tire crown;

[0008] The left tire shoulder is provided with a slightly oblique long strip wide transverse groove and a slightly oblique short strip fine groove. The slightly oblique long strip wide transverse groove and the slightly oblique short strip fine groove form a "human" shaped pattern groove, and the two adjacent sets of "human" shaped pattern grooves are designed with variable pitch.

[0009] The right tire shoulder is provided with two slightly oblique long strip wide grooves and two oblique short strip fine grooves. The two slightly oblique long strip wide lateral grooves and two oblique short strip fine grooves are combined to form an inverted "V" shaped tread pattern. A slightly oblique long strip fine lateral groove is provided between the two sets of inverted "V" shaped tread pattern grooves, and the adjacent inverted "V" shaped tread pattern grooves and slightly oblique long strip fine lateral grooves are designed with variable pitch.

[0010] Preferably, the tire crown is divided into a left tire crown pattern block, a right tire crown pattern block, and a middle tire crown pattern block by two longitudinal grooves.

[0011] Preferably, the left-side tire crown tread block is provided with inverted "V"-shaped fine grooves, and the two adjacent sets of inverted "V"-shaped fine grooves are designed with variable pitch.

[0012] Preferably, the right-side tread block is provided with a fine oblique groove and a slightly oblique short fine transverse groove, which are combined to form a "V"-shaped groove; the right-side tread block is also provided with a triangular fine groove, which is located on the right side of the right-side tread block, and the pitch between the triangular fine groove and the "V"-shaped groove is varied.

[0013] Preferably, the intermediate tread block is provided with a "V"-shaped fine groove, and a short transverse groove is provided between two adjacent "V"-shaped fine grooves. The short transverse groove is located on the left side of the intermediate tread block, and the "V"-shaped fine groove and the short transverse groove are designed with a variable pitch.

[0014] Preferably, the cross-sections of the micro-sloping elongated wide horizontal groove one, the sloping short strip fine groove one, the micro-sloping elongated wide groove two, the sloping short strip fine groove two, the micro-sloping elongated fine horizontal groove, the inverted "V" shaped fine groove, the fine sloping groove one, the micro-sloping short fine horizontal groove, the triangular fine groove, the "V" shaped fine groove, and the short horizontal groove are all wedge-shaped.

[0015] Beneficial Effects: Compared with existing technologies, this utility model adopts a wedge-shaped tread groove design (such as slightly inclined long strip wide transverse groove one, oblique short strip fine groove one, slightly inclined long strip wide groove two, etc., all grooves have a wedge-shaped cross section), which effectively enhances the overall rigidity of the tread blocks. This structure makes the tread blocks deform less during tire driving, especially during acceleration, braking and steering, and can transmit driving force and braking force more stably, significantly improving the vehicle's handling response speed and driving stability, meeting the higher demands of new energy vehicles for tire handling performance due to their power characteristics; by optimizing the arrangement of adjacent tread grooves with variable pitch, the vibration frequency generated when the tread blocks contact the ground is effectively disrupted, suppressing the generation of resonance noise; on the other hand, the semi-closed and closed shoulder design (the tread structure of the left and right shoulders) improves the rigidity of the shoulder tread blocks, while blocking the transmission path of internal tire noise to the vehicle, providing users with a comfortable and quiet driving experience under the dual effect.
