Description

  • The The invention relates to a multi-plate clutch for a motor vehicle with non-rotatable about Belaganbindungsmittel connected to a first shaft, axially movable friction linings and with rotationally fixed on a second shaft arranged pressure plates, wherein at least one of the pressure plates for clamping the friction linings and generating a frictional connection between the two shafts axially is movable.
  • A multi-disc dry clutch is from the DE 195 17 968 A1 known. Here Belaganbindungsmittel different friction linings are provided with a radially inwardly facing teeth and arranged axially displaceable in a toothing of a hub connected to the first shaft. Between the friction liners intermediate discs are axially displaceable and rotatably connected to the second shaft. Upon engagement of the clutch, one of the pressure plates moves in the direction of the other pressure plate and clamped arranged on both faces of the pad springs friction linings and the intermediate discs together. The pad springs are moved together with the friction linings in the direction of the other pressure plate. As a result, the frictional connection between the waves is produced.
  • adversely in the known multi-plate clutch is that the Belaganbindungsmittel when in the engaged Incorporate the state of the multi-plate clutch into the toothing of the hub can. this leads to at the subsequent move out to ensure that the friction linings first in remain in their position and at the intermediate discs and fixed application ring grind.
  • By the DE 34 37 741 A1 is a multi-plate clutch has become known, in which the intermediate disks each have spring elements and push away from each other when disengaged. This prevents that adjacent intermediate discs remain in a state clamping the friction linings. The disadvantage here, however, is that the Belaganbindungsmittel as in the DE 195 17 968 A1 work into the teeth of the hub and therefore can grind in the disengaged state of the coupling to the intermediate discs.
  • From the US 3,174,602 a friction clutch is known in which spring fingers come out of the region of the friction linings in order to press the friction linings away from the counter friction surfaces. These spring fingers should provide a secure separation of the friction linings from the counter friction surfaces. Due to the fixed clamping of the friction lining carrier on the hub, however, a permanent grinding of the spring fingers during engagement and disengagement is generated. This results in a disturbing drag torque during the coupling process, which does not remain constant due to the wear of the spring fingers.
  • Of the Invention is based on the problem, a multi-plate clutch of the type mentioned above so that a grinding of the friction linings in disengaged State of the coupling is largely avoided.
  • This Problem is solved by the invention An embodiment according to the characterizing part of claim 1.
  • By This design will be the friction linings when moving apart the pressure plates individually biased in their vorgese Henen positions and therefore of the intermediate discs and the pressure plates separated. A snagging the friction linings in the indented Condition is reliably avoided by the spring means. Therefore, the friction linings in disengaged Do not grind the state of the multi-disc clutch. Another advantage this design is that the friction linings thanks The invention no further springs for a high Einkuppelkomfort need.
  • The Pad spring could For example, a welded to a sheet metal part for holding the friction linings coil spring or have a protruding spring tongue. However, the pad spring has according to a advantageous development of the invention, a large axial Spring travel and can be at the same time particularly cost-effective produce when the pad spring is designed meandering.
  • The Incorporation and subsequent Persistence of the pad springs in the grooves can be according to another advantageous Development of the invention almost exclude, if the pad springs in their movable and in the groove penetrating areas slightly narrower are as the grooves. This allows the pad springs are supported on the walls of the grooves, if with the multi-plate clutch according to the invention transmit very high moments should be. When later disengaging the First lift the clutch the pad springs from the walls of the grooves and then move the friction linings in the axial direction. The pad springs can therefore be at an actuation of the Multi-disc clutch in the grooves of the hub in the axial direction without friction move. Therefore leads even incorporation of the pad springs in the hub when applying the circumferential force due to the clutch torque due to the engagement not to a grinding of the friction linings on the intermediate discs or the pressure plates.
  • The grooves may be part of the toothing of the hub of the known multi-disc group ment and thus be arranged parallel to the first wave. However, the circumferentially acting on the pad springs forces can be supported very close to the pad springs, without the hub particularly deep grooves needed when the grooves are arranged substantially perpendicular to the first shaft. With this design, the pad springs can be designed particularly soft.
  • The Hub could for example, manufactured together with the grooves as a casting or as Blechtiefziehteil be. The hub has, however, according to a another advantageous embodiment of the invention a particular low weight, if the grooves of bends of a support plate are limited.
  • Of the meander-shaped Range of pad springs could be designed almost arbitrarily. However, the pad springs are according to a another advantageous embodiment of the invention in tangential Direction very stiff when in each case from the attachment to the Wave a radially away leg and afterwards a first U-shaped Bend and bend from one to a second U-shaped bend out Have limbs and guided by the bend to the friction linings leg, where the friction linings holding legs at least partially disposed within the groove is. Support this the friction linings are under load in the groove. The attachment the friction linings on the pad springs can thereby be designed cohesively, since the Belagfedern by their elastic design a comfortable operation of the inventive multi-plate clutch enable.
  • The Pad springs are according to a another advantageous development of the invention reliably the hub fastened when the pad springs one in the grooves of an edge of the hub in the central region axially guided leg to have.
  • The Position of the pad springs can be just set it on the hub before mounting, if the pad springs a bead around the edge of the hub. Furthermore, the beading contributes to the initiation of on the friction linings acting axial forces in the hub.
  • There the friction linings when pressed the coupling according to the invention be either away from each other or moved towards each other on the friction linings acting forces evenly absorbed by the pad springs, if the lining springs of the friction linings are arranged mirror-symmetrically to each other. This will be a reliable position the friction linings ensured. For several juxtaposed, a common friction lining retaining pad springs can the pad springs to compensate for angular deviations of the legs be alternately arranged in mirror image.
  • The coupling according to the invention is particularly cost-effective, when the hub on the first shaft together with one of the friction linings axially slidably angeord net is and if all other friction linings the elastic have deformable pad springs. As the first wave mostly off a hardened one Material exists and the hub in the area of the shaft is very wide is, the risk of incorporating the hub into the shaft is particularly low held.
  • The Hub is designed according to a other advantageous development of the invention constructive particularly simple, when the hub arranged on the first shaft hub sleeve and one on the hub shell arranged drive plate for holding the pad springs has. Of course can also be several according to the number of friction linings Carrier discs on the hub shell Fasten.
  • The Hub has according to one another advantageous embodiment of the invention, a high stability, if the drive plate two mirror symmetry arranged to each other Sheet metal parts have and when the sheet metal parts close to their outer circumference Spacers are attached. Continue on the hub For example, simply attach two or four friction linings.
