Abstract

A vehicle wheel assembly ( 1 ) for supplying compressed air from a vehicle axle to a tyre ( 3 ) comprises a vehicle wheel ( 5 ) and a control valve assembly ( 7 ). The wheel ( 5 ) comprises a wheel hub ( 9 ) for mounting the wheel ( 5 ) to a vehicle (V); and a wheel rim for mounting a tyre ( 3 ) on the wheel ( 5 ). A transfer line ( 19 ) is provided in the wheel for transferring compressed air from the wheel hub to the wheel rim ( 11 ) for inflating the tyre ( 3 ). The control valve assembly ( 7 ) comprises an inlet, an outlet and a control valve ( 25 ) operably located between the inlet and the outlet for controlling passage of compressed air between the inlet and the outlet. The control valve assembly ( 7 ) is removably disposed in the wheel hub ( 9 ) such that fluid communication is established between the control valve assembly ( 7 ) and the transfer line ( 19 ).

First claim

1 - 41 . (canceled)

42 . A control valve assembly comprising:
an inlet for receiving compressed air from a supply line; an outlet for supplying compressed air to a transfer line; and a control valve for selectively placing the inlet in fluid communication with the outlet; wherein the control valve assembly is configured to be removably disposed in a wheel hub, and wherein the control valve assembly comprises securing means for releasably securing the control valve assembly to the wheel hub.

43 . A control valve assembly according to claim 42 , wherein the control valve comprises a first valve member movable between an open position and a closed position along a longitudinal axis, and wherein the control valve is configured such that, in use, the longitudinal axis is arranged substantially co-axially with a rotational axis of a wheel.

44 . A control valve assembly according to claim 42 , wherein the control valve is a pneumatically actuated control valve.

45 . A control valve assembly according to claim 44 , wherein the pneumatically actuated control valve is a latching valve.

46 . A vehicle wheel assembly for supplying compressed air to a tire, the vehicle wheel assembly comprising a control valve assembly according to claim 42 , and a wheel, the wheel comprising:
a wheel hub for mounting the wheel to a vehicle; a wheel rim for mounting a tire on the wheel; and a transfer line for supplying compressed air to a tire mounted on the wheel.

47 . A vehicle wheel assembly according to claim 46 , the wheel further comprising a wheel valve for controlling the flow of air through said transfer line.

48 . A vehicle wheel assembly according to claim 47 , wherein the wheel valve is configured to cooperate with the control valve assembly such that the wheel valve is opened when the control valve assembly is disposed in the wheel hub, and/or the wheel valve is configured to close when the control valve assembly is removed from the wheel hub.

49 . A vehicle wheel assembly according to claim 48 , wherein the wheel valve comprises a second valve member which is displaced to an open position when the control valve assembly is disposed in the wheel hub.

50 . A vehicle wheel assembly according to claim 49 , wherein the second valve member is movable along a first axis arranged substantially parallel to, or substantially coincident with a rotational axis of the wheel.

51 . A vehicle wheel assembly according to claim 46 , wherein the control valve assembly is inserted into the wheel hub from an inner side of the wheel.

52 . A vehicle wheel assembly according to claim 51 , wherein, when the vehicle wheel assembly is mounted to a vehicle wheel hub, the control valve assembly is disposed between the wheel hub and the vehicle wheel hub.

53 . A vehicle wheel comprising:
a wheel hub for mounting the wheel to a vehicle; a wheel rim for mounting a tire on the wheel; a transfer line for supplying compressed air to a tire if the tire is mounted on the wheel; and a wheel valve for controlling the flow of air through said transfer line, wherein the wheel has lateral inner and outer sides, the wheel hub being configured removably to receive a control valve assembly from the inner side of the wheel, wherein a cavity is formed in said wheel hub for receiving the control valve assembly, the cavity being open towards an inner side of the wheel, and wherein the wheel valve is configured to cooperate with the control valve assembly such that the wheel valve is opened when the control valve assembly is received in the wheel hub, and/or the wheel valve is configured to close when the control valve assembly is removed from the wheel hub.

54 . A vehicle wheel according to claim 53 , wherein the wheel valve comprises a first valve member which is displaced to an open position when the control valve assembly is disposed in the wheel hub.

55 . A vehicle wheel according to claim 53 , wherein the transfer line is formed in a hollow spoke or in a tube connecting the wheel hub and the rim, wherein the transfer line is in fluid communication at one end thereof with a wheel hub opening and at the other end thereof with a rim opening.

56 . A vehicle wheel according to claim 53 , wherein the transfer line is in fluid communication at one end thereof with the cavity and at the other end thereof with a rim opening.

57 . A vehicle wheel according to claim 53 , wherein the cavity comprises an annular recess for receiving securing means of the control valve assembly for securing the control valve assembly when inserted thereinto.

58 . A vehicle wheel according to claim 53 , wherein the cavity comprises axial retaining means for retaining a control valve assembly inserted into the cavity at a prescribed axial location.

59 . A vehicle wheel according to claim 58 , wherein the axial retaining means comprises an annular projection extending from an inner surface of the cavity, optionally wherein the cavity defines a circular aperture in the outer side of the wheel hub and the annular projection is disposed at an end of the cavity adjacent to the outer side.

60 . A vehicle wheel according to claim 53 , in combination with a tire mounted on the wheel rim.
