Description

TECHNICAL FIELD

[0001] The utility model relates to tire manufacturing technical field especially relates to a kind of unmanned vehicle high control low-noise tire. BACKGROUND

[0002] With the rapid development of science and technology, unmanned vehicles are increasingly widely used in logistics, travel, industrial operations and many other fields. The operation of unmanned vehicles relies on advanced sensors, algorithms and control systems. However, as the key component that directly contacts the ground, the performance of tires is crucial to the overall performance of unmanned vehicles.

[0003] Most of the unmanned vehicles on the market still use ordinary tires. Ordinary tires are designed mainly for the needs of traditional manned vehicles and have many shortcomings in meeting the special performance requirements of unmanned vehicles.

[0004] Firstly, in terms of ease of control, unmanned vehicles require tires to accurately execute the steering, braking and other instructions issued by the system. The pattern and structural design of ordinary tires are relatively conventional, and they cannot provide sufficient precision for unmanned vehicles, leading to problems such as steering deviation and unstable braking distance during vehicle operation, affecting the safety of unmanned vehicle operation and the accuracy of task execution.

[0005] Secondly, the noise performance is also an important factor in the application of unmanned vehicles. In some noise-sensitive scenarios, such as urban residential area distribution and hospital internal transportation, the noise generated by ordinary tires during operation not only causes interference to the surrounding environment, but also may affect the working accuracy of the sensors of the unmanned vehicle itself, reducing its ability to accurately perceive the information of the surrounding environment.

[0006] In addition, unmanned vehicles often need to operate continuously for a long time, and the durability and reliability of tires are extremely high. Therefore, the performance of ordinary tires in terms of wear resistance and fatigue resistance cannot meet the high-intensity use requirements of unmanned vehicles, and frequent tire replacement not only increases the operating cost, but also may affect the normal operation efficiency of the unmanned vehicle.

Detailed Implementation

[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0022] Example

[0023] Please refer to the accompanying drawings in the specification. In this embodiment of the present invention, a high-handling, low-noise tire for unmanned vehicles includes a tire crown 1 and a tire shoulder 2. The tire crown 1 is provided with a group of pattern blocks, which includes a first pattern block 101, a second pattern block 102, a third pattern block 103, a fourth pattern block 104, a fifth pattern block 105, and a sixth pattern block 106. The first pattern block 101, the second pattern block 102, the third pattern block 103, the fourth pattern block 104, the fifth pattern block 105, and the sixth pattern block 106 are arranged sequentially from left to right. The right-hand arrangement is as follows: the first flower block 101 and the sixth flower block 106 are cross-symmetrical structures; the second flower block 102 and the fifth flower block 105 are cross-symmetrical structures; the third flower block 103 and the fourth flower block 104 are cross-symmetrical structures; a pattern groove 107 is provided between the first flower block 101 and the second flower block 102; a pattern groove 108 is provided between the third flower block 103 and the fourth flower block 104; and a pattern groove 109 is provided between the fifth flower block 105 and the sixth flower block 106.

[0024] The tire shoulder 2 is uniformly provided with transverse grooves 201, and two transverse slots 202 are provided between two transverse grooves 201.

[0025] Multiple mud-discharging and sound-breaking grooves 3 are evenly arranged on the flower block group.

[0026] The first pattern block 101, the second pattern block 102, the third pattern block 103, the fourth pattern block 104, the fifth pattern block 105 and the sixth pattern block 106 are longitudinally continuous zigzag structures. The first pattern block 101, the second pattern block 102, the third pattern block 103, the fourth pattern block 104, the fifth pattern block 105 and the sixth pattern block 106 are variable pitch designs. Two adjacent pattern blocks 5 on the pattern block group have the same structure, and the pattern blocks 5 are interconnected without gaps.

[0027] A longitudinal tortuous groove 4 is provided between the second flower block 102 and the third flower block 103, and a longitudinal tortuous groove 4 is also provided between the fourth flower block 104 and the fifth flower block 105.

[0028] The patterned blocks on the first patterned block 101, the second patterned block 102, the third patterned block 103, the fourth patterned block 104, the fifth patterned block 105 and the sixth patterned block 106 are all made of 3D steel sheet 6. The patterned blocks made of 3D steel sheet have high hardness and wear resistance, and can withstand greater friction without being easily worn.

[0029] The tire shoulder 2 is a closed tire shoulder structure, which can effectively reduce driving resonance noise and provide a quiet driving environment.

[0030] Working Principle: When the autonomous vehicle issues commands such as steering and braking, friction is generated between the tires and the ground. Due to the unique structural design of the tread blocks (symmetrical structure, longitudinally continuous zigzag structure, variable pitch design, etc.), the friction distribution between the tire and the ground is more uniform and controllable. The interconnection and specific arrangement of the tread blocks can more accurately transmit the vehicle's power and torque, enabling the tires to precisely execute system commands and perform steering and braking operations, thus ensuring the stability and accuracy of the autonomous vehicle's operation. During tire movement, air flows between the tire and the ground, generating vibrations and noise. The mud-removing and sound-breaking grooves disrupt the airflow path, making the airflow more dispersed and irregular, reducing the intensity of air vibrations and thus reducing noise generation. The closed shoulder structure prevents disordered airflow in the tire shoulder area, further reducing noise propagation and achieving a low-noise effect. The tread blocks made of 3D steel sheets have high hardness and wear resistance, capable of withstanding significant friction without easily wearing down. Meanwhile, the lateral grooves and slots on the tire shoulder effectively distribute the pressure on the tire, reducing localized wear and making the tire wear more even. This improves the tire's wear resistance and fatigue resistance, ensuring its durability and reliability.

[0031] In summary, this utility model features a longitudinally curved groove design for the crown and a wide, continuous design for the crown tread blocks, effectively improving straight-line driving performance and enhancing safety during unmanned autonomous driving. The crown employs a closed shoulder design, effectively reducing driving resonance noise and providing a quiet driving environment. The crown tread blocks utilize 3D steel sheets, effectively improving grip, reducing tread block heat generation, and extending service life. Mud-removing and sound-breaking grooves are added to the tread blocks, increasing the contact area and improving mud-removing efficiency; these grooves also effectively break up compressed airflow during driving, reducing noise. The entire tread block assembly adopts a variable pitch design, with irregular steel sheets and orderly tread blocks arranged in a coordinated manner to improve maneuverability during driving.
