Abstract

The invention relates to a compressor assembly for supplying pressure medium to a tire cavity of a vehicle wheel that can be mounted on a wheel hub which can be mounted on a wheel carrier so as to be rotatable about an axis of rotation. The compressor assembly includes a wheel mount-side transmission component including a cylindrical cam.

First claim

The invention claimed is:

1.

at least one hub-side compression chamber ( 40 , 42 ) including a volume that is altered by a translatory movement of a compressor component ( 36 ), wherein a pressure medium that is to be conducted into the tire cavity is pressurized by reducing the volume of the compression chamber ( 40 , 42 ), and
a transmission ( 33 ) configured to convert a rotational movement between the wheel mount and the hub to an oscillating translatory movement of the compressor component ( 36 ) through an interaction of a first transmission component ( 44 ) that does not rotate relative to the wheel mount ( 16 ) with a second transmission component ( 34 ) rotatable with the wheel hub ( 18 ), wherein the first transmission component ( 44 ) comprises a cylindrical cam ( 52 ), and the first transmission component ( 44 ) is located radially inward of the second transmission component ( 34 ).

2. The compressor assembly ( 10 ) according to claim 1 , wherein the first transmission component ( 44 ) comprises a groove-like cam track ( 50 ).

3. The compressor assembly ( 10 ) according to claim 2 , wherein the second transmission component ( 34 ) comprises a pin-like engagement element ( 48 ) that engages the cylindrical cam ( 52 ) in the groove-like cam track ( 50 ).

4. The compressor assembly ( 10 ) according to claim 1 , wherein the second transmission component ( 34 ) comprises a tappet output drive.

5. The compressor assembly ( 10 ) according to claim 1 , wherein the translatory movement of the compressor component ( 36 ) takes place at least in part in a direction of the axis of rotation ( 29 ).

6. The compressor assembly ( 10 ) according to claim 1 , wherein the cylindrical cam ( 52 ) has at least one curved surface ( 72 ), which runs toward the axis of rotation in at least a portion of a curve seen from a radial perspective ( 66 ).

7. The compressor assembly ( 10 ) according to claim 1 , wherein the first transmission component ( 44 ) comprises a groove-like cam track ( 50 ), wherein the cam track ( 50 ) has two opposing curved surfaces ( 72 ), each of which runs toward the axis of rotation in at least a portion of curves seen from a radial perspective ( 66 ).

8. The compressor assembly ( 10 ) according to a claim 1 , further comprising a compression chamber ( 40 , 42 ) located, seen along the axis of rotation ( 29 ), in front of and behind a contact section of the second transmission component ( 34 ) having the cylindrical cam ( 52 ).

9. The compressor assembly ( 10 ) according to claim 1 , wherein the second transmission component ( 34 ) is movable to a position interacting with the first transmission component ( 44 ) through a translatory movement in a radial direction ( 66 ).

10. The compressor assembly ( 10 ) according to claim 1 , wherein the second transmission component ( 34 ) is moved to a position interacting with the first transmission component ( 44 ) through a rotational movement about the radial direction ( 66 ).

11. The compressor assembly ( 10 ) according to claim 1 , further comprising two second transmission components ( 34 ) that are diametrically opposed in relation to the axis of rotation ( 29 ).

12. The compressor assembly ( 10 ) according to claim 1 , further comprising a coupling mechanism ( 62 ) configured to bring the second component ( 34 ) into interaction with the first transmission component ( 44 ).

13. The compressor assembly ( 10 ) according to claim 1 , further comprising a measuring and/or indicating mechanism ( 210 ) connected to the tire cavity ( 24 ) by a pressure medium line ( 22 ), the mechanism ( 210 ) measuring and/or indicating a pressure, temperature, and/or moisture of the pressure medium in the tire cavity ( 24 ).

14. The compressor assembly ( 10 ) according to claim 1 , further comprising a filter ( 200 ) at a pressure medium intake end.

15. The compressor assembly ( 10 ) according to claim 14 , wherein the pressure medium from the tire cavity ( 24 ) or by conveying the pressure medium through the compressor assembly ( 10 ), cleans the filter ( 200 ).

16. A compressor assembly ( 10 ) for supplying a pressure medium to a tire cavity ( 24 ) of a tire on a vehicle wheel mounted on a wheel hub ( 18 ), wherein the wheel hub ( 18 ) can be mounted on a wheel mount ( 16 ) such that it can rotate about an axis of rotation ( 29 ), the compressor assembly ( 10 ) comprising:
at least one hub-side compression chamber ( 40 , 42 ) including a volume that is altered by a translatory movement of a compressor component ( 36 ), wherein a pressure medium that is to be conducted into the tire cavity is pressurized by reducing the volume of the compression chamber ( 40 , 42 ),
a transmission ( 33 ) configured to convert a rotational movement between the wheel mount and the hub to an oscillating translatory movement of the compressor component ( 36 ) through an interaction of a first transmission component ( 44 ) that does not rotate relative to the wheel mount ( 16 ) with a second transmission component ( 34 ) rotatable with the wheel hub ( 18 ), wherein the first transmission component ( 44 ) comprises a cylindrical cam ( 52 ), wherein the second transmission component ( 34 ) comprises an engagement element ( 48 ) that engages in the cylindrical cam ( 52 ), wherein the engagement element ( 48 ) has a cross section at an end ( 70 ) facing the first transmission component ( 44 ), an extension of which broadens, seen from a radial perspective ( 66 ).
