Definitions
- the invention relates to a Kupplungszentralaus Weger with a housing, with one of the actuation of a clutch unit serving Lager-Avemienring which is independent of rotation a translation dependent on an adjacent thereto bearing inner ring which is attached to a piston attached, which is axially movable in the housing is guided, further comprising a Vorlastfederanlagenng ring in operative contact with the bearing inner and the piston is located, the community of piston Vorlastfederanlagenng, bearing inner ring is arranged translationally movable relative to the housing and at least Vorlastfederanlagenng a magnetic field disturbing material Further, wherein a sensor fixed to the housing is arranged so as to determine the position of Vorlastfederstromrings and thus at least indirectly, the position of the piston.
- sensors have been used so far, which sense a displacement of the magnet attached to the piston. Hall sensors were often used.
- outer ring or inner ring are used for a bearing outer ring or a bearing inner ring of a comprehensive release bearing this.
- Such aggregates which are also referred to as central disengers, are known, for example, from the patent application DE 10 2008 006 060 A1.
- DE 10 2008 006 060 A1 discloses a slave cylinder for a vehicle clutch with a device formed by at least one magnet and at least one sensor operatively connected therewith for the distance measurement and position determination of a piston which is axially movably mounted in a cylindrical housing covered by a dirt sleeve surrounded by a retaining ring, wherein the sensor on the housing is brought, which is protected from dust and external stresses and relatively inexpensive to produce by each sensor is assigned a positionally mounted on the retaining ring magnet.
- At least the Vorlastfederstromring consists of a material which, when flow of a current through the sensor, a magnetic field is formed, which is sensitive to the position of Vorlastfederstromrings of the sensor, so at least one of the elements Group of Vorlastfederstromring, inner ring and outer ring made of metal, such as steel or aluminum.
- at least one of these elements has a material which acts magnetic field disturbing and is thus perceived by the sensor.
- the position of the corresponding interfering element can be precisely determined. Since the elements of the group of pistons, Vorlastfederstromring, bearing inner ring are mutually attached in a translation direction dependent on each other, the position of each of these four elements can be calculated accurately calculated. If the Vorlastfederan lax ring directly on the outside of the sensor is supported or rests against the outside of the sensor, a good guidance of Vorlastfederstromringes is ensured in a translational displacement.
- Vorlastfederstromringes can also be realized if the sensor has at least two substantially radially inwardly directed and mutually parallel rails between which the Vorlastfederstromring rests movably mounted. A possibly occurring rotation of the inner ring is then not passed on to the outer ring, since the Vorlastfederstromring prevents this.
- the senor has two ribs oriented orthogonally to the rails on opposite sides which are inserted into grooves adapted to these.
- the degrees of freedom can be further reduced if three tolerance compensation elements are each formed on the radially inwardly and outwardly facing surfaces of the ribs. These tolerance compensation elements are advantageously designed in each case round and form with the ends of a defined plane.
- tolerance compensation elements are formed as nubs from the outer material of the sensor, then simple manufacturing methods can be used, such as injection molding.
- the senor includes a coil surrounded by a glass fiber reinforced plastic with 10% to 15% friction modified Teflon.
- the coil in turn should advantageously be arranged flow-through in the plastic and still have corresponding externally accessible connections.
- the coil is designed as a circuit board with milled coil winding. If the sensor is positively locked in a receptacle in the housing by means of at least one snap hook and wherein on the snap hook nearest surface extending in the longitudinal direction of the recording extending three round tolerance compensation buffer, which define a plane, the sensor can be particularly accurate in the recording insert and position end.
- the ribs and rails compress! are designed and adapted on the side of the snap hook. This makes it easier to insert the sensor into the receptacle.

- FIG. 2 is a detail view of FIG. 1 with a sensor and an adjacent thereto
- FIG. 3 is a perspective view of the Kupplungszentralausschreibers of FIG. 1,
- Fig. 4 is a front view of the Kupplungszentralausschreibers of FIGS. 1 and 3 and
- FIG. 5 is a detail front view of the sensor of FIG .. 4
- a first embodiment of a Kupplungszentralausschreibers 1 is shown.
- This Kupplungszentralausschreiber 1 is also referred to as Concentric Slave Cylinder (CSC).
- CSC Concentric Slave Cylinder
- the housing in the true sense is provided with the reference character 2.
- the bearing inner ring 4 of the release bearing connected to the piston 10 serves to actuate a Clutch assembly, in particular the contacting with clutch actuator spring tongues.
- a bearing outer ring 3 Adjacent to the bearing inner ring 4, a bearing outer ring 3 is arranged, which together with the intermediate balls form the release bearing.
- the position of the Vorlastfederanla low 5 and thus the position of the over the bearing inner ring 4 connected to this piston 10 is detected by a sensor 6.
- At least one rolling element 7 is arranged between the latter, which is formed in the embodiment shown in FIG. 1 as a ball.
- the preload spring 8 is supported on the one hand Vorlastfederanlagenng 5 and on the other hand on the housing 2 from. Adjacent to a guide sleeve 9, the piston 10 is also arranged, which is separated by a seal 11 from a pressure chamber 12.
- the sensor 6 has a circuit board, not shown, which comprises a coil.
- the coil is surrounded by an outer material 14 of the sensor 6.
- the outer material 14 is preferably PA66-GF20 or PA66-GF35.
- at least one of the outer material 14 is preferably PA66-GF20 or PA66-GF35.
- Fig. 2 At least one of three tolerance buffers is shown, which ensures a precise positioning in the longitudinal direction of a receptacle 16, in which the sensor 6 is located.
- a fastening device 17 is further shown with holes 18 for attachment of the Kupplungszentralaus Wegers 1 to a clutch bell or a transmission component.
- the spatial positioning of the sensor 6 is shown offset by 5 ° from a y-axis.
- Fig. 5 rails 19 are aligned radially inwardly and shown parallel to each other, between which the preload spring 8 is movably guided. Orthogonal to the rails 19 and ribs 20 are formed. On the surfaces 21 three punctiform tolerance compensation elements in the form of knobs are mounted, each forming a defined surface with their ends.
- the nubs are just as compressible or at least as compressible as the outer material 14 of the sensor 6.
