Abstract

A cover is provided for a cylinder arrangement having at least one cylinder. The cover is suitable for sealingly covering a cylinder opening of the cylinder. At least one sensor unit for capturing a measurement variable within the cylinder is integrated in the cover.

Claims

1. A component of a cylinder arrangement having at least one cylinder, comprising:

a cover operatively configured to sealingly cover a cylinder opening of the cylinder;

a sensor unit integrated at least partially into the cover, the sensor unit being configured to detect a measured variable within the cylinder; and

a fastener for the cover, wherein

a socket is formed in the cover, the socket accommodating the fastener, and

the sensor unit comprises a coil accommodated in the cover, the coil being arranged to at least partially surround the socket.

2. The component according to claim 1, wherein the cover is made of a cast cover material.

3. The component according to claim 2, wherein the sensor unit is cast at least partially into the cast cover material.

4. The component according to claim 3, further comprising:

a cable arranged to pass out of the cover on an opposite side from the sensor unit in relation to the cover, the cable being connectable with the sensor unit.

5. The component according to claim 1, further comprising:

a cable arranged to pass out of the cover on an opposite side from the sensor unit in relation to the cover, the cable being connectable with the sensor unit.

6. The component according to claim 1, further comprising:

a seal operatively configured to seal-off the cylinder from the outside, the seal being arranged in an interior region of the cylinder.

7. The component according to claim 1, wherein the socket has an opening facing the outside of the cylinder.

8. A cylinder arrangement, comprising:

a plurality of cylinders having cylinder openings; and

a cover for the cylinder arrangement, the cover being operatively configured to sealingly cover the cylinder openings of the cylinders; and

a fastener for the cover, wherein

a socket is formed in the cover and is configured to accommodate the fastener, and

a sensor unit for detecting a measured variable within at least one cylinder is integrated at least partially into the cover;

wherein the sensor unit comprises a coil accommodated in the cover, the coil being arranged so as to partially surround the socket.

9. The cylinder arrangement according to claim 8, wherein the cover is made of a cast cover material.

10. The cylinder arrangement according to claim 9, wherein the sensor unit is cast at least partially into the cover.

11. A vehicle, comprising:

an automatic transmission having a cylinder arrangement;

wherein the cylinder arrangement includes a plurality of cylinders having cylinder openings;

a cover for the cylinder arrangement, the cover being operatively configured to sealingly cover the cylinder openings of the cylinders; and

a fastener for the cover, wherein

a socket is formed in the cover and is configured to accommodate the fastener,

a sensor unit for detecting a measured variable within at least one cylinder is integrated at least partially into the cover, and

the sensor unit comprises a coil accommodated in the cover, the coil being arranged so as to partially surround the socket.
