Abstract

A wheel assembly having a wheel rotation axis; a rim with an outer surface around the wheel rotation axis; wherein the outer surface comprising suction ports; two tires mounted on the outer surface of the rim; a particle collector adapted to trap particles entering said particle collector; a particle suction system with a bladed suction structure configured for generating a suction air flow in the rim upon rotation of said bladed suction structure about the wheel rotation axis; an air passage connecting the suction ports to the bladed suction structure via the particle collector in order to suck particles through the suction ports by means of the suction air flow generated by the bladed suction structure.

First claim

What is claimed is:

1 . A wheel assembly comprising:
a wheel rotation axis; a first face; a second face axially at the opposite of the first face; a rim around the wheel rotation axis; a first tire and a second tire which are mounted around the rim, which are respectively at the first face and at the second face, and which comprise a tire outer diameter; an outer circular groove with a circular bottom surface forming the rim and axially between the first tire and the second tire, said circular bottom surface comprising a bottom diameter which is smaller than the tire outer diameter; suction ports through the circular bottom surface; a particle collector; a particle suction system configured for generating a suction airflow through the wheel assembly upon rotation of said particle suction system about the wheel rotation axis; an air passage connecting the suction ports to the particle suction system in order to suck particles with the suction ports, wherein the air passage comprises a first disc-shaped portion radially extending from the suction structure toward the wheel rotation axis, and a second disc-shaped portion extending from the suction ports toward the wheel rotation axis.

2 . The wheel assembly according to claim 1 , wherein the particle suction system comprises a first bladed suction structure arranged at the first face, and a second bladed suction structure arranged at the second face, the particle collector axially extending along the first bladed suction structure and the second bladed suction structure, and the suction ports being arranged axially between the first bladed suction structure and the second bladed suction structure.

3 . The wheel assembly according to claim 1 , wherein the suction ports define a circular array surrounding the particle collector, said particle collector comprising a cylindrical body extending along the wheel rotation axis.

4 . The wheel assembly according to claim 1 , wherein the particle collector comprises a filtering body which is arranged at one of the first face and the second face; the air passage connecting the suction ports to the particle collector through the particle suction system.

5 . A wheel assembly comprising:
a wheel rotation axis; a rim with an outer surface around the wheel rotation axis; said outer surface comprising suction ports; two tires mounted on the outer surface of the rim; a center hub; a particle collector adapted to trap particles entering said particle collector, said particle collector being arranged in the center hub; a particle suction system configured for generating a suction airflow adapted to suck particles at an interface between the two tires and a ground surface; an air passage connecting the suction ports to the particle suction system through the particle collector in order to suck particles through the suction ports by means of the suction air flow generated by the particle suction system, wherein the center hub separates the particle suction system from the particle collector; and wherein the center hub comprises a fixation device adapted to secure the particle collector to the center hub, and wherein the particle collector comprises two circular outlets, and one circular inlet arranged axially between the two circular outlets.

6 . The wheel assembly according to claim 5 , wherein the rim comprises an outer ring and the particle suction system comprises a bladed suction structure physically connecting the center hub to the outer ring.

7 . The wheel assembly according to claim 5 , wherein the wheel assembly comprises an outer circular groove with a circular bottom surface, the suction ports being through the circular bottom surface.

8 . The wheel assembly according to claim 5 , wherein the wheel assembly comprises a brake disc surrounded by the suction ports, the brake disc being axially at the opposite side with respect to the particle suction system.

9 . The wheel assembly according to claim 5 , wherein the wheel assembly comprises a first side and a second side axially at the opposite of the first side; the wheel assembly further comprises a filtering body at the first side, and the second side is an inboard side.

10 . A wheel assembly comprising:
a wheel rotation axis; a rim with an outer surface around the wheel rotation axis; said outer surface comprising suction ports; two tires mounted on the outer surface of the rim; a center hub; a particle collector adapted to trap particles entering said particle collector, said particle collector being arranged in the center hub; a particle suction system configured for generating a suction airflow adapted to suck particles at an interface between the two tires and a ground surface; an air passage connecting the suction ports to the particle suction system through the particle collector in order to suck particles through the suction ports by means of the suction air flow generated by the particle suction system, wherein the wheel assembly comprises a first side and a second side axially at the opposite of the first side; the wheel assembly further comprises a filtering body at the first side, and the second side is an inboard side.

11 . The wheel assembly according to claim 10 , wherein the rim comprises an outer ring and the particle suction system comprises a bladed suction structure physically connecting the center hub to the outer ring.

12 . The wheel assembly according to claim 11 , wherein the center hub separates the particle suction system from the particle collector; and wherein the center hub comprises a fixation device adapted to secure the particle collector to the center hub, and wherein the particle collector comprises two circular outlets, and one circular inlet arranged axially between the two circular outlets.

13 . The wheel assembly according to claim 12 , wherein the wheel assembly comprises an outer circular groove with a circular bottom surface, the suction ports being through the circular bottom surface.

14 . The wheel assembly according to claim 13 , wherein the wheel assembly comprises a brake disc surrounded by the suction ports, the brake disc being axially at the opposite side with respect to the particle suction system.
