Definitions

  • the invention relates to a clutch according to the preamble of the main claim.
  • a piston of a linear motor additionally serves directly as an inner disk carrier and is connected in a rotationally fixed and axially movable manner to an output shaft as one of two connecting members for torque transmission via a driving profile, and part of the cylinder of the linear motor serves additionally directly as an outer disk carrier and is firmly connected to the second connecting member in the form of a planet carrier.
  • the output shaft completes the cylinder.
  • the first sealing ring is arranged between the piston and the output shaft. It only has to endure axial displacements corresponding to the actuation path of the linear motor. Movements in the circumferential direction are completely avoided by the driving profile.
  • the second sealing ring is arranged between the two parts of the cylinder, the outer disk carrier and the output shaft. He has to endure both circumferential speeds corresponding to the diameter of the output shaft and the speed difference between the two disk carriers, as well as slight axial displacements in accordance with his own axial compliance with pressure changes.
  • the third sealing ring is arranged between the two
  • Lamellar carriers on a large sealing diameter near the fins It has to endure both large peripheral speeds and large axial displacements in accordance with the actuation path of the linear motor.
  • the invention has for its object to improve a coupling according to the preamble of the main claim so that one of the three sealing rings is omitted and the other two sealing rings only have to endure axial displacements.
  • the cylinder as an inner disk carrier and to design the piston as an intermediate member for torque transmission between the inner disk carrier and the drive shaft.
  • the two elements of the linear motor Arranged radially between the lamellae and the drive shaft, the two elements of the linear motor additionally take over the transmission of the entire torque, in accordance with their natural radial order.
  • An existing installation space is used twice. Further advantages are achieved with the characteristic features of the subclaims which are known per se.
  • the drawing shows a section of a longitudinal section through a multi-plate clutch according to the invention in the open state.
  • a piston 2 of a linear motor 3 is rotatably fixed via a driving profile 4 and axially fixed between a shaft collar 5 and a locking ring 6.
  • a cylinder 7 is arranged in a rotationally fixed manner via a driving profile 8 and is axially movable to a limited extent by an annular end face 9 of the piston 2 and a locking ring 10.
  • a plate spring 11 between the locking ring 10 and the piston 2 presses the cylinder 7 axially against the end face 9.
  • a radially outer sealing ring 12 is arranged in a circumferential groove 13 in an outer surface 14 of the piston 2 and slides axially in a hollow cylinder surface 15 of the cylinder 7.
  • a radially inner diameter ring 16 is arranged in a circumferential groove 17 in an inner surface 18 of the cylinder 7 and slides axially on a cylinder surface 19 of the piston 2.
  • the cylinder 7 carries in an outer driving profile 20 non-rotatable and axially movable inner plates 21 and one End plate 22.
  • the end plate 22 is axially supported by a collar 23 of the cylinder 7.
  • the cylinder 7 is thus also an inner plate carrier 7.
  • An outer plate carrier 24 carries in an inner driving profile 25 non-rotatably and axially movable outer plates 26.
  • a retaining ring 27 in a circumference ⁇ groove 28 in the driving profile 25 supports an end plate 29 and thus all the slats 21, 22, 2nd 6 axially against the outer disk carrier 24.
  • the outer disk carrier 24 is at the same time additionally a planet carrier 24 with planet bolts 30 and, on roller bearings 31, planet gears 32 of a planetary gear 33, which is only partially shown.
  • the drive shaft 1 is also a central gear 1 of the planetary gear 33.
  • the drive shaft 1 and the planet carrier 24 are the two connecting members 1, 24 for torque transmission.
  • Pressure fluid in a chamber 34 between the piston 2 and the cylinder 7, supplied via bores 35, 36 in the drive shaft 1 and in the piston 2, pushes the cylinder 7 and thus also the end plate 22 axially against the other plates 21, 26 and the end plate 29, and thus closes the multi-plate clutch.
  • the restoring force of the plate spring 11 must be overcome.
  • the actuating force of the multi-plate clutch is supported by an axial needle bearing 37 between the piston 2 and the outer plate carrier 24.
  • the plate spring 11 pushes the cylinder 7 back again and thus opens the multi-plate clutch again.

Abstract

L'accouplement à lamelles est actionné par un moteur linéaire à fluide (3). Le piston (2) du moteur linéaire (3) est asocié rigidement avec l'arbre d'entraînement (1). Le cylindre (7) de moteur linéaire (3) ne peut tourner et peut se déplacer axialement avec le piston (2). Le cylindre (7) porte en plus les lamelles intérieures de l'accouplement. Le moteur linéaire (3) est disposé radialement à lintérieur des lamelles (21, 22, 26) et axialement à l'intérieur du support des lamelles extérieures (24).
