Definitions

• Multi-plate clutch for motor vehicles especially motorcycles
• 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 gear On a transmission input shaft 10, a gear, the so-called primary wheel 11 is rotatably mounted with a roller bearing.
• the primary wheel 11 is driven by the crankshaft (not shown) of an internal combustion engine.
• With the primary wheel 11 is a housing, the so-called basket 12 rotatably connected.
• 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 driving lamellae are toothed on their outer periphery. Their teeth engage in corresponding grooves of the clutch basket 12.
• the driven blades engage with teeth in corresponding grooves of the driver 13, which is rotatably and axially fixed to the transmission input shaft 10.
• 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.
• a release bearing 19 is inserted, which is supported with an annular flange on the pressure pot 16.
• a cylindrical pressure mushroom 20 is inserted, which is supported with an annular flange on the inner ring.
• a multi-plate clutch with the structure described above is well known, so that a more detailed explanation is unnecessary.
• Novel is the design and storage of the pressure fungus 20.
• This has a concentric cylindrical extension 21 which is guided in a concentric bore 22 of the transmission input shaft 10 to an axial displacement without play.
• the pressure plate 14 is centered and on the other hand, a concentric initiation of the release force is ensured when opening the clutch.
• a direct restriction of the tilting game is effected.
• a misalignment of the pressure plate 14 is reliably prevented. This circumstance allows the use of a diaphragm spring 17 with a falling from the operating point in the direction of actuation characteristic.
