Abstract

In order to mount an object such as a tire pressure monitoring device on a vehicle road or landing wheel, the object is mounted on a mounting member which is in turn secured to the wheel by using one or more wheel nuts which hold the wheel on a hub in the normal manner but also pass through apertures in the mounting member and have projecting flanges which secure the mounting member on the wheel; a resilient member is used between the mounting member and the wheel so that the force applied to the mounting member is a resilient force, enabling the wheel nut to be tightened fully onto the wheel.

Claims

1. A vehicle road or landing wheel secured to a wheel hub having a plurality of projecting, externally screw-threaded, wheelsecuring studs, said studs projecting through corresponding apertures in said wheel and internally threaded wheel nuts being screwed onto said studs and having front portions engaging said wheel to secure said wheel on said hub, sAid wheel having tire pressure monitoring components mounted thereon by means of a mounting assembly comprising:

a mounting member having an aperture therethrough through which a said wheel stud projects, whereby said mounting member retains said tire pressure monitoring components in place, a wheel nut screwed onto the wheel stud projecting through the aperture in the mounting member said wheel nut having a front portion passing through said aperture in said mounting member and engaging said wheel, and a rear portion having a radiallyprotruding surface between the front portion and the rear portion which surface engages said mounting member and secures said mounting member to said wheel, a resilient member which applies a force to said mounting member upon tightening said wheel nut fully against said wheel, thereby holding said mounting member firmly in position on said wheel, and means for preventing rotation of said mounting member about said aperture therein, the remainder of said wheel nuts not having a radially protruding surface whereby the mounting member may be installed or removed without removing all of the wheel nuts securing the wheel to the hub.

2. A wheel as claimed in claim 1 wherein said rotation preventing means comprises another aperture in said mounting member through which another wheel stud projects and a wheel nut having said radially protruding surface screwed onto said wheel stud the front portion of said wheel nut passing through said aperture and engaging said wheel and said surface engaging said mounting member.

3. A wheel as claimed in claim 1, wherein said mounting member is in the form of a complete annulus.

4. A wheel as claimed in claim 1, wherein said mounting member is secured by two or more said nuts having said radially-protruding surface.

5. A wheel as claimed in claim 1, wherein said radially-protruding surface on said wheel nut is provided by a flange around the nut, leaving enough room at the rear end of the nut for engagement by a wheel spanner.

6. A wheel as claimed in claim 1, wherein said wheel nut having said radially-protruding surface has a hexagonal rear portion and a cylindrical front portion, the diameter of the cylindrical front portion being substantially less than the distance between opposite edges of the rear portion, and the front and rear portions being separated by a flange which provides said radially-protruding surface, said flange being annular with a diameter substantially greater than the diameter of the front portion.

7. A wheel as claimed in claim 1, wherein said resilient member is positioned between said mounting member and said wheel.

8. A wheel as claimed in claim 1 wherein said resilient member is a pad secured to at least one of said tire pressure monitoring components.

9. A wheel as claimed in claim 1 wherein said wheel carries a pneumatic tire and wherein said tire pressure monitoring comprise means for providing a source of electric current supply, a pneumatic transducer, a radio frequency transmitter for energization by said transducer and at least one pipe providing air communication between said pneumatic tire and said transducer.

10. A wheel as claimed in claim 1 wherein said mounting member has at least one additional aperture for mounting at least one of said tire pressure monitoring components, said component protruding out through said additional aperture and having a projection which is held behind said mounting member.

11. A wheel as claimed in claim 8 wherein said mounting member has at least one additional aperture for mounting at least one of said tire pressure monitoring components, said component protruding out through said additional aperture and having a projection which is held behind said mounting member.
