With the implementation of new energy automobiles and strict fuel emission standards, environmental pollution caused by pollutant particles due to non-combustion emission in the traffic field is getting more and more attention. The tire wear particles belong to non-combustion discharged pollutants in the traffic field, and not only comprise tread component particles, but also include tire and pavement volatile matters generated after the tire rubs with pavement at high temperature and derived condensed particles, such as rubber asphalt condensate, pavement ash, and the like, and the particles volatilize into the air and are condensed with some atmospheric particles to form aerosol particles. The particles and derived particles generated after the tire is worn release more than 50 chemical substances into the atmosphere and have toxicity, and certain potential harm is caused to the formation of atmospheric pollution, soil pollution, fresh water organism survival and human health.
The abrasion particles and the derived particles of the tire are peeled off from the tread, are separated from the interface and are subjected to the action of a plurality of airflow fields and volatilized into the atmosphere, and always accompany the whole life cycle of the tire service; therefore, if tire wear particles that are separated from the ground contact interface can be trapped (accumulated and caught) in real time, so that the tire wear particles are volatilized into the atmosphere as little as possible, it will have an important meaning to reduce secondary pollution caused by tire wear, and will have an important positive effect on improving the environmental quality and improving the ecological environment.
At present, the research on reducing rubber particles is mostly to change the rubber performance by changing the rubber formula and the like so as to improve the wear resistance of the rubber and reduce the rubber wear particles; further studies have found that, as the vehicle travels in the space between the exterior of the vehicle tyre and the housing, when the vehicle is traveling at low speeds, i.e. at a vehicle speed V < 60km/h, particulate matter is mainly concentrated at the front upper position of the wheels under the action of the corresponding air flow field; when the automobile runs at a high speed, namely the speed V is more than 60km/h, the speed is faster, and the particles are mainly concentrated at the rear side of the wheels under the action of the corresponding airflow field; the collection of the tire wear particles by arranging a special collection device is not found in the market, and particularly, the collection of the tire wear particles can be realized with higher efficiency when an automobile runs at a low speed or a high speed.

In the above-mentioned angle range, through simulation experiments of the air flow field between the outside of the tire and the housing during running of the automobile, it was found that the second collecting channel 12 was optimal for capturing particles when β4=140° and β4- β3=30°, i.e., β3=110°, the opening angle of the second inlet 14 and the second outlet 15 was 20 °.
The width of the second collecting channel 12 in this configuration is kept consistent with the width of the first collecting channel 1; in addition, the height H3 of the second collection channel 12 in the radial direction of the automobile tire ranges in size from: h3 is more than or equal to 30 and less than or equal to 80mm.

1. the trapping device fully considers trapping efficiency and simultaneously considers the automobile structure, so that the existing automobile can be modified at low cost, and the trapping device has good practicability;
2. as shown in fig. 11, simulation and test showed that: when the automobile runs at a low speed, namely the speed V is less than or equal to 60km/h, tire wear particles with the particle size of 2.5-10 mu m are mainly concentrated at the front upper part of the wheels under the action of an airflow field, the tire wear particle trapping efficiency is 18-30% when the trapping device only comprises a first collecting channel 1, the tire wear particle trapping efficiency is increased to 28-35% when the first collecting channel 1 and the second collecting channel 12 are combined, and the tire wear particle trapping efficiency is highest when the first collecting channel 1 and the second collecting channel 12 and the auxiliary collecting channel 8 reach 31-36%;
when the automobile runs at a high speed, namely the automobile speed V is more than 60km/h, the tire wear particles with the particle size of 2.5-10 mu m are mainly concentrated at the rear side of the wheel under the action of an airflow field, in the high speed state, the tire wear particle trapping efficiency when the trapping device only comprises the first collecting channel 1 is 30-45%, the tire wear particle trapping efficiency when the first collecting channel 1 and the second collecting channel 12 are combined is increased to 35-45%, and the tire wear particle trapping efficiency when the first collecting channel 1 and the second collecting channel 12 and the auxiliary collecting channel 8 is 36-46%;
