As the improvement of above-mentioned annular grounding contact, described grounding contact is designed to needle-like, the root of each grounding contact connects the crown conductive layer, and the tip passes outwards through wearing layer and extends to the crown ground plane.This structure has kept the integraty of crown wearing layer under guaranteeing the little preceding topic of discharge effect influence, guaranteed its bulk strength.When cooperating with netted crown conductive layer, it is good that described needle-like grounding contact is arranged on crown conductive layer mesh node place.
As another kind of improvement the of the present invention, the rubber part of whole tire is all adopted the conductive rubber manufacturing.
Equip the vehicle of antistatic wheel tyre of the present invention, on its car body metal piece since a variety of causes produced electric charge and run up to when to a certain degree forming the voltage to ground difference, the metal car body can with this part charge guiding nearby wheel rim and import the earth by the conductive layer of being located on the tire, because wheel connected to chassis continuity, the electric charge that is produced can't roll up high potential, so effluve is contained in bud.
The present invention compared with prior art has the following advantages and effect: 1, the car body electric charge directly by the multiple spot release over the ground of each wheel, has continuity and the bad contact problem can not occur; 2, be not subjected to the influence of environmental change, release electrostatic is thorough.There are a plurality of wheels simultaneously the electric charge of different parts on the car body to be discharged along separate routes over the ground nearby, overcome the single-point grounding chain halfway problem of discharging, fundamentally eliminated the accumulation of electric charge and the charge difference that vehicle body resistance causes; 3, have electromagnetic shielding action, electromagnetic radiation energy that various electrical equipment produces in the car is played shielding action.Because wheel is a conductor, whole locomotive body is in ground state all the time, not only can not accumulate electrostatic charge continuously on the car body, can also shield electromagnetic radiation; 4, do not take any vehicle body space and do not influence any car body outward appearance yet.
