A non-pneumatic wheel with tread partitions

Abstract

The invention discloses a non-inflatable wheel with a zoned tire tread. The non-inflatable wheel with the zoned tire tread comprises a zoned wheel rubber main body, an elastic connecting frame, a wheel rim and a wheel spoke, which are arranged in sequence from inside to outside with a wheel axle as center, wherein the wheel spoke is mounted on the wheel axle; the wheel rim is connected with the wheel spoke; the elastic connecting frame is connected with the wheel rim; the zoned wheel rubber main body is connected with the elastic connecting frame; the zoned wheel rubber main body is divided into a plurality of zone blocks through a plurality of zone connecting grooves; the zone connecting grooves comprise longitudinal zone connecting grooves in a circumferential direction of the wheel; and the zone connecting grooves further comprise transverse zone connecting grooves in an axial direction of the wheel. Through the adoption of the non-inflatable wheel with the zoned tire tread according to the invention, problems that a non-inflatable tire touches the ground non-uniformly and self-adaption of the tire thread of the non-inflatable tire is poor can be effectively solved, the ground touching surface is maximized and the adhesion situation between the wheel and the ground is improved; and the non-inflatable wheel with the zoned tire tread is suitable for vehicles to run under a plurality of road conditions.

Description

technical field [0001] The invention relates to a non-pneumatic wheel with tread partitions, which belongs to the technical field of non-pneumatic tires. Background technique [0002] Non-pneumatic tires have significant advantages such as stab-proof, bullet-proof, and non-puncture, and are widely used in engineering vehicles, military vehicles and other wheeled equipment with harsh driving environments. Non-pneumatic tires mainly include solid tires, spring tires, honeycomb bionic structure tires and other types, and have been widely used in engineering vehicles, planetary exploration vehicles and military wheeled vehicles. However, solid tires are heavy, which affects the maneuverability of the vehicle, so they are mainly used in engineering vehicles that do not require high maneuverability and speed; spring tires mainly rely on the elastic deformation of springs to replace the elasticity of rubber inflation, and the impact of complex road loads on The anti-fatigue perfor...

AI Technical Summary

Problems solved by technology

However, solid tires are heavy, which affects the maneuverability of the vehicle, so they are mainly used in engineering vehicles that do not require high maneuverability and speed; spring tires mainly rely on the elastic deformation of springs to replace the elasticity of rubber inflation, and the impact of complex road loads on The anti-fatigue performance of the deformation element of the spring tire is high, and the ordinary spring is difficult to meet the mechanical performance requirements of the spring tire; the honeycomb bionic tire adopts the honeycomb elastic structure instead of the rubber inflatable elasticity, and the performance of the wheel is improved due to the high-performance composite honeycomb bionic structure material. However, the wheels of this structure are easily affected by foreign objects in the driving environment, and the dynamic balance will be destroyed after being embedded in the wheel, especially when driving at high speed, the imbalance will bring greater vibration shock to the vehicle

[0003] In addition to the technical deficiencies caused by the respective structural characteristics and material properties of the above-mentioned non-pneumatic tires, they also have a common disadvantage, that is, the tire is relatively rigid, and the tread ground contact uniformity and envelope characteristics are poor.

Due to the non-pneumatic structure and the tread as a whole, the overall rigidity of this type of wheel is relatively high. When driving on uneven roads, gravel roads and other off-road roads, the uniformity of the tire ground contact area and the envelope characteristics are poor. The force and grip become poor, and the wheels often cause problems such as slipping and sinking when rolling, thereby reducing the traction performance of the vehicle
