Definitions
- the invention relates to a fluid-actuated piston-cylinder unit with a piston which is slidably mounted in a cylinder in the direction of a piston axis and secured against rotation about the piston axis, wherein the piston with a first end of a push rod and a second end of the push rod with a Release lever for actuating a release element, in particular a clutch, is connected, wherein the push rod - with respect to a rotation about the piston axis - is rotatably connected both with the piston, and with the release lever.
- segment magnets in place of ring magnets brings cost advantages - a segment magnet, for example, costs one-tenth of a ring magnet - and causes fewer problems in the allocation of space.
- segment magnets are arranged only in certain peripheral regions of the piston, the piston must, however, be secured against rotation in the cylinder, which is associated with additional design effort.
- a pressure medium-actuated piston-cylinder unit is proposed with a piston which carries a permanent magnet and having one or more magnet-sensitive sensors on the periphery of the cylinder.
- the permanent magnet is in the radial direction from the piston and is guided in a longitudinal groove of the cylinder jacket to thereby form an anti-rotation device for the piston.
- a clutch servomechanism with a displaceably mounted in a cylinder piston which against rotation around the piston axis is secured.
- a first end of a push rod is connected to the piston, a second end of the push rod to a release lever.
- the push rod is rotatably connected to the release lever with respect to a rotation about the piston axis.
- a disadvantage is that additional processing steps in the production of anti-rotation for the piston-cylinder unit are required.
- the object of the invention is to avoid these disadvantages and to determine the position and the stroke of the piston with low manufacturing and construction costs.
- an anti-twist device for the piston should be realized in the simplest possible way.
- the piston is fixedly connected to a piston rod, which - preferably via a first pin - rotatably connected to the push rod in connection.
- first bolt through which the connection between the push rod and the piston takes place, is arranged in a first bore of the push rod arranged transversely to the piston axis, the connection between push rod and release lever preferably being effected by a second bolt which is transverse to the longitudinal axis the push rod is arranged in a second bore of the push rod.
- the first and second bolts are designed as dowel pins, which connect the components to be secured piston and push rod or push rod and release lever so that no rotation about the piston axes is possible.
- the first bolt is secured by a captive against displacement transversely to the piston axis, wherein the captive can be preferably formed by shoulders of the piston.
- the first bolt can be firmly pressed into a transverse bore of the piston rod. Furthermore, it can be provided that the piston is fixedly connected to a piston rod, which - preferably via the first bolt - rotatably in communication with the push rod, wherein preferably the first bolt is firmly pressed into a transverse bore of the piston rod. In order to avoid an unintentional displacement of the first bolt, this can be secured against movement transversely to the piston axis, preferably by the piston itself.
- the second pin is firmly pressed into the second bore of the push rod, wherein preferably the two ends of the second bolt protrude from the second transverse bore and - in the direction of rotation about the piston axis - are positively connected to the release lever, wherein preferably the two ends of the second bolt engage in arranged substantially in the direction of the piston axis longitudinal grooves of the release lever.
- the two ends of the push rod can thereby - at least in sections - have a spherical surface, preferably the first end and / or the second end - at least partially - has a spherical surface and in a correspondingly reciprocal spherical recess of the piston or the piston rod or is embedded in the release lever.
- the measurement of the Kobenhubes or the position of the piston can thus be carried out in a simple manner, if the distance measurement in a peripheral region of the piston at least one - is arranged - preferably exactly one - magnetic segment, which cooperates with a housing-fixed displacement sensor.
- FIG. 1 shows a piston-cylinder unit according to the invention in a first
- FIG. 2 shows the piston-cylinder unit in a second oblique view.
- Fig. 5 shows a release lever together push rod in an oblique view.
- Fig. 6 shows the piston-cylinder unit in detail corresponding to the section along the line IV-IV in Fig. 3;
- FIG. 7 shows the piston-cylinder unit in a section along the line VII-VII in Fig. 3rd
- the figures show a piston-cylinder unit 1 according to the invention, in the present case for actuating a clutch, not shown, of a vehicle.
- the piston-cylinder unit 1 has a housing 2 with a cylinder 3, in which a piston 4 is displaceably mounted in the direction of the piston axis 4a.
