Piston cylinder assembly having integrated measuring device
View Patent ↗A piston-cylinder assembly, in particular for pneumatic, hydraulic or mechatronic systems, includes a cylinder housing and a piston. The piston is coupled to a piston rod and disposed in the cylinder housing such that it can move along a longitudinal axis. A measuring device for detecting piston or piston rod position is provided inside the cylinder housing.
1. A piston-cylinder assembly, comprising:
a cylinder housing;
a piston disposed in the cylinder housing;
a trailer piston movable axially relative to the piston; and
a measuring device configured to measure the position of the piston, the measuring device including a sensor and a ring magnet.
2. The piston-cylinder assembly as claimed in claim 1 , wherein the sensor extends substantially parallel to a longitudinal axis of the piston.
3. The piston-cylinder assembly as claimed in claim 1 , wherein the piston is disposed in the cylinder housing such that it is movable along a longitudinal axis.
4. The piston-cylinder assembly as claimed in claim 1 , wherein the piston is coupled to a piston rod.
5. The piston-cylinder assembly as claimed in claim 1 , wherein each of the sensor and the ring magnet is at least partially disposed within a recess of the trailer piston.
6. The piston-cylinder assembly as claimed in claim 1 , wherein at least a portion of the sensor traverses through the ring magnet when the piston moves along a longitudinal axis.
7. A piston-cylinder assembly, comprising a cylinder housing; a cylinder cover; a piston disposed in the cylinder housing; and a measuring device configured to measure the position of the piston, the measuring device including a magnet and a sensor integrated into the cylinder cover.
8. The piston-cylinder assembly as claimed in claim 7 , wherein the cylinder cover comprises a sensor housing integrally formed thereon.
9. The piston-cylinder assembly as claimed in claim 8 , wherein the sensor is disposed within the sensor housing.
10. The piston-cylinder assembly as claimed in claim 7 , wherein the magnet is disposed adjacent the sensor housing.
11. A piston-cylinder assembly, comprising:
a cylinder housing;
a piston disposed in the cylinder housing; and
a measuring device configured to measure the position of the piston, the measuring device including a sensor and a ring magnet,
wherein at least a portion of the sensor traverses through the ring magnet when the piston moves along a longitudinal axis.
12. The piston-cylinder assembly as claimed in claim 11 , wherein the sensor extends substantially parallel to a longitudinal axis of the piston.
13. The piston-cylinder assembly as claimed in claim 11 , wherein the piston is disposed in the cylinder housing such that it is movable along a longitudinal axis.
14. The piston-cylinder assembly as claimed in claim 11 , wherein the piston is coupled to a piston rod.
15. The piston-cylinder assembly as claimed in claim 11 , further comprising a trailer piston movable axially relative to the piston.
16. The piston-cylinder assembly as claimed in claim 15 , wherein each of the sensor and the ring magnet is at least partially disposed within a recess of the trailer piston.
