Abstract:
Disclosed is a wheel for vehicles, in particular with electric or hybrid propulsor, apt to recover at least a part of the energy which is required in order to deform the tire of the wheel during its rotation and to transfer the energy, recovered in this manner, from the wheel to the vehicle on which the wheel is mounted, so that this energy, recovered, is used to generate the electrical energy intended to feed the devices installed on the vehicle, such as in particular the respective electric propulsor.

Claim (Index 1):
Wheel ( 1 ;  101 ) for vehicles comprising a rim ( 2 ;  102 ) provided with a hub ( 3 ;  103 ) which defines the rotational axis of the wheel and a tyre ( 4 ;  104 ), associated circumferentially with said rim ( 2 ;  102 ), apt to come into contact with the ground (S) during the rotation of the wheel ( 1 ;  101 ), the wheel comprising:\n a plurality of hydraulic actuators ( 5 ;  105 ) oriented in radial direction and placed in said tyre ( 4 ;  104 ), between the latter and said rim ( 2 ;  102 ), each of said hydraulic actuators ( 5 ;  105 ) in turn comprising a cylinder ( 6 ;  106 ), constrained to said rim ( 2 ;  102 ) or to said tyre ( 4 ;  104 ), in which cylinder a piston ( 7 ;  107 ) is slidably housed and associated with a rod ( 8 ;  108 ) projecting from said cylinder ( 6 ;  106 ) and constrained to said tyre ( 4 ;  104 ) or to said rim ( 2 ;  102 ); at least one delivery way ( 11 ;  111 ) and at least one return way ( 12 ;  112 ) formed in the hub ( 3 ;  103 ) of the wheel ( 1 ;  101 ); a plurality of delivery pipes ( 9 ;  109 ) for connecting and placing in communication each cylinder ( 6 ;  106 ) of said hydraulic actuators ( 5 ;  105 ) with said delivery way ( 11 ;  111 ); a plurality of return pipes ( 10 ;  110 ) for connecting and placing in communication each cylinder ( 6 ;  106 ) of said hydraulic actuators ( 5 ;  105 ) with said return way ( 12 ;  112 ); a first plurality of flow control valves ( 13 ;  113 ) placed in said delivery pipes ( 9 ;  109 ) and configured to allow a single-direction circulation of a hydraulic oil from the cylinder ( 6 ;  106 ) of each hydraulic actuator ( 5 ;  105 ) towards said delivery way ( 11 ;  111 ), when the piston ( 7 ;  107 ) of the hydraulic actuator ( 5 ;  105 ) moves towards the interior of the cylinder ( 6 ;  106 ), because of the deformation of the zones of the tyre ( 4 ;  104 ) which come into contact, at each turn of the wheel ( 1 ;  101 ), with the ground (S) during the movement of the vehicle whereon the wheel ( 1 ;  101 ) is mounted; a second plurality of flow control valves ( 14 ;  114 ) placed in said return pipes ( 10 ;  110 ) and configured to allow a single-direction circulation of hydraulic oil from said return way ( 12 ;  112 ) towards the cylinder ( 6 ;  106 ) of each hydraulic actuator ( 5 ;  105 ), when the piston ( 7 ;  107 ) of the hydraulic actuator ( 5 ;  105 ) moves towards the exterior of the cylinder ( 6 ;  106 ), because of the return into the non-deformed configuration of the zones of the tyre ( 4 ;  104 ) at each turn of the wheel ( 1 ;  101 ) at the end of the contact with the ground (S) during the movement of the vehicle; and at least one rotating valve ( 15 ,  16 ;  115 ) associated with the hub ( 3 ;  103 ) of the wheel ( 1 ;  101 ) and comprising a rotating delivery manifold ( 15 ) and a rotating return manifold ( 16 ), said rotating valve ( 15 ,  16 ;  115 ) being apt to connect and place in communication, via the respective rotating delivery manifold ( 15 ), said delivery pipes ( 9 ;  109 ) with said delivery way ( 11 ;  111 ) and, via the respective rotating return manifold ( 16 ), said return pipes ( 10 ;  110 ) with said return way ( 12 ;  112 ), wherein said wheel ( 1 ;  101 ) is apt to recover, in the form of pressure energy of the hydraulic oil which flows in said pipes ( 9 ,  10 ;  109 ,  110 ), at least a part of the energy which is consumed in order to deform the tyre ( 4 ;  104 ), during the rotation of the wheel ( 1 ;  101 ), and to transfer, via the delivery way ( 11 ;  111 ) and the return way ( 12 ;  112 ) associated with the hub ( 3 ;  103 ) of the wheel ( 1 ;  101 ), the energy, recovered in this manner, from the wheel ( 1 ;  101 ) to the vehicle on which the same wheel ( 1 ;  101 ) is mounted, so that this recovered energy is used in the same vehicle and in particular is converted into electrical energy intended to feed the devices installed on the vehicle.
