  • the invention relates to a multi-plate clutch for motor vehicles, especially motorcycles comprising a primary wheel coupled to the flywheel of an internal combustion engine, which is rotatably mounted on a transmission input shaft, a clutch basket rigidly connected to the primary wheel, a concentrically arranged to the transmission input shaft and rigidly connected to this driver with the driver axially displaceable, but rotatably connected pressure plate, a rigidly connected to the pressure plate pressure pot, a diaphragm spring, which is supported on an outer peripheral portion of the driver and an inner peripheral portion of the pressure pot, a package of annular clutch plates, which alternately on the inside or outer circumference with the driver, or with the basket rotatably, but axially displaceably connected, wherein the lamellae are clamped between the pressure plate and the driver, a coaxially arranged to the transmission input shaft release bearing, on the an axial disengaging force is transferable to the pressure plate, and a pressure mushroom inserted into the inner ring of the release bearing and with an annular
  • the manual force required to disengage which the driver must exert on the clutch lever
  • the hand force to be exerted on the clutch lever is constant over the entire actuating travel.
  • the use of a diaphragm spring with a degressive from the operating point in the direction of actuation characteristic is proposed. By this falling characteristic can be reduced in a cost effective manner, the work required to open the clutch because the manual force decreases over the path of the clutch lever. This means a significant gain in comfort for the driver.
  • the invention has for its object to improve the multi-plate clutch according to the invention to the extent that upon actuation a misalignment and an eccentric force is prevented.
  • this object is achieved in that the pressure fungus is provided with an extension which is guided in a bore of the transmission input shaft to a coaxial movement.
  • This measure ensures that the actuating force is introduced concentrically into the coupling. Furthermore, a misalignment is prevented due to further component tolerances and radial games.
  • the multi-plate clutch according to the invention is therefore suitable for use of a diaphragm spring with a falling from the operating point in the direction of actuation characteristic.
  • a diaphragm spring offers a cost-effective way of reducing the clutch force and thus a significant gain in comfort for the driver.
  • With the pressure mushroom guided in the transmission input shaft centering of the pressure plate is achieved in an effective and cost-effective manner.
  • the inventive measure can be realized in the existing space and brings only a small extra weight with it.
  • a multi-plate clutch is shown schematically in longitudinal section.
  • the multi-plate clutch shown in the drawing is intended in particular for use in a motorcycle.

  • a driver 13 is rotatably and axially fixed to the transmission input shaft 10.
  • a pressure plate 14 is rotatably connected to the driver 13, but axially displaceably connected.
  • the pressure plate 14 has a plurality of domes 15 extending axially between the spokes of the driver 13.
  • a pressure pot 16 is with the pressure plate 14 rigidly connected. More specifically, the pressure pot 16 is bolted to the domes 15.
  • An annular diaphragm spring 17 is supported on the driver 13 at the outer circumferential region and on the pressure pot 16 at the inner peripheral region. Between the driver 13 and the pressure plate 14, a package of annular clutch plates 18 is clamped. In succession, driving and driven blades 18 are arranged alternately.

  • the fins 18 are axially displaceable in the associated grooves of the basket 12 and the driver 13. The fins 18 run in an oil bath, which is why one speaks of a wet clutch.

  • the pressure plate 14 is centered and on the other hand, a concentric initiation of the release force is ensured when opening the clutch.

Abstract

L’invention concerne un embrayage à disques multiples pour véhicules motorisés, notamment pour motocyclettes, comprenant une roue (11) primaire couplée avec le volant d’un moteur à combustion interne et montée de manière à pouvoir tourner sur un arbre (10) d’entrée de boîte de vitesses, un panier (12) d'embrayage relié de manière rigide avec la roue primaire, un élément (13) d’entraînement disposé de manière concentrique par rapport à l’arbre d’entrée de boîte de vitesse et relié de manière rigide avec celui-ci, une plaque (14) de compression pouvant coulisser dans le sens axial avec l’élément d’entraînement, mais reliée de manière à ne pas pouvoir tourner, un pot (16) de compression relié de manière fixe avec la plaque de compression, un ressort (17) à membrane qui s’appuie par une zone de pourtour extérieure sur l’élément d’entraînement et par une zone de pourtour intérieure sur le pot de compression, un groupe de disques (18) d’embrayage de forme annulaire qui sont reliés en alternance au niveau du pourtour intérieur ou extérieur avec l'élément d'entraînement ou avec le panier de manière à ne pas pouvoir tourner, mais à pouvoir coulisser dans le sens axial, les disques étant montés entre la plaque de compression et l’élément d’entraînement, un palier (19) de débrayage disposé de manière coaxiale par rapport à l’arbre d’entrée de boîte de vitesses par le biais duquel une force de débrayage axiale peut être transmise à la plaque de compression, et un poussoir (20) en forme de champignon introduit dans la bague intérieure du palier de débrayage et reposant sur celui-ci avec une bride annulaire. Le poussoir (20) en forme de champignon est doté d’un prolongement (21) qui pénètre dans un orifice (22) de l’arbre (10) d’entrée de boîte de vitesse afin d’exercer un mouvement coaxial.
