Definitions

  • the invention relates to a mounting device for installing a disc clutch of a motor vehicle transmission concentric to the axis of the crankshaft, consisting of a coaxially drilled threaded spindle, which is provided at one end with a fixed rotary handle and / or with a key profile and an adjustable nut is screwed onto the external thread , and from an axially displaceably mounted in the threaded spindle, provided with a threaded shank, which is provided with a threaded nut lying on the end face of the threaded spindle and which on its opposite side protruding from the threaded spindle at least one expanding cone protruding into a radially expandable clamping sleeve having.
  • Such mounting devices are used in such a way that the radially expandable adapter sleeve is clamped in the central retainer of the clutch disc with the aid of the expansion cone and that the clutch housing is then manually aligned concentrically with the clutch disc. With the help of the clamping nut, which is clamped against the plate spring plate of the disc clutch, the clutch disc is held in its position centered on the clutch housing.
  • a single expansion cone is provided for expanding a clamping sleeve. This is arranged on the end of the mandrel opposite the threaded nut.
  • the expansion sleeve is made of plastic and partially protrudes into an enlarged bore of the hollow threaded spindle and is supported there on a radial shoulder.
  • the end of this threaded sleeve protruding from the threaded spindle is divided by a plurality of radially continuous axial slots into expansion sectors which allow axial expansion when the expansion cone is pulled into the free end of the expansion sleeve on the front side.
  • the spreading sectors are thus connected on one side to the closed, non-expandable part of the clamping sleeve. Due to the radial expansion by means of the expansion cone, the individual expansion segments of the adapter sleeve therefore assume a position which is oblique to the axis, that is to say also conical, so that even if their outer surface has a cylindrical shape in the relaxed state, the expansion segments have only their extreme end edge on the Fit the inner surface of the hub to be clamped.
  • the hub therefore has no secure hold, it tilts to assume an oblique position, by means of which the centering of the clutch disc with respect to the clutch housing or with respect to the axis of the crankshaft or with respect to a drive shaft to be later pulled into the hub is at least made more difficult, if not questioned.
  • an inclined position of the clutch disc is a hindrance if it is to be aligned directly with the axis of the crankshaft, but this is not possible anyway with this known device.
  • the invention has for its object to improve a mounting device of the type mentioned so that this disadvantage is avoided and ensured that an inclined position of the clutch disc is inevitably avoided when clamping the expansion device in the hub of a clutch disc, in which it is ensured that between the adapter sleeve and the inner surface of the hub not only have a linear shape, but also a planar support extending over the length of the adapter sleeve or the length of the hub.
  • one or two clamping sleeves each consisting of at least three separate cylinder sectors, held together only by an annular clamping element, are arranged on the mandrel in the region of two axially offset expansion cones, which have cone angles of equal size, or are, the individual cylinder sectors are each provided with the lateral surfaces of the expansion cones corresponding expansion surfaces.
  • the fairly simple and safe alignment of the clutch disc on the axis of the crankshaft is particularly simple when the crankshaft is provided on the end face with a central bore or with a radial bearing for the gear shaft, into which or which the centering pin, which can be provided with a replaceable centering sleeve, can be inserted in a centering manner.
  • the assembly device can nevertheless be used very advantageously by first aligning the clutch disc clamped on the assembly device with respect to the axis of the clutch housing and then screwing the clutch housing with the clutch disc clamped in the centered position onto the flywheel of the crankshaft becomes. The assembly device can then be completely removed from the disk coupling by loosening the expansion device.
  • the embodiment according to claims 6 and 7 is a variant which is equivalent in terms of function and handling, in which the expansion cones are arranged directly on the mandrel and are provided with a single clamping sleeve which is assigned to them jointly and which also consists of separate cylinder sectors consists.
  • the mounting device shown in Fig. 1 for installing a disc clutch of a motor vehicle transmission coaxial to the flywheel or the crankshaft consists of a coaxially pierced threaded spindle 1 made of metal with an external thread 2 and a rotary handle 3 arranged in one piece at one end, which has a disc-like shape and has a knurled grip 4 on its circumferential surface and which only serves to hold the threaded spindle in place.
  • the opposite end section, which adjoins a radial annular shoulder 5, is provided with an expansion cone 6, which is also formed in one piece and which has an identically shaped second expansion cone 7 of a mandrel 8 opposite, ie mirror image, is opposite.
  • the mandrel 8 is mounted in an axially displaceable manner in a central guide bore 9 and, at its end section opposite the second expansion cone 7, has a rear side out of the threaded spindle 1 protruding threaded shaft 10, on which a threaded nut 11 is screwed, which is provided on its cylindrical circumference with a handle cord 12, and which is supported on the end face on a rear, annular end face 13 of the threaded spindle 1 or the rotary handle 3 in the axial direction.
  • the guide bore 9 extends only over about half the length of the threaded spindle 1. The remaining bore 9 'has a larger diameter.
  • clamping nut 14 On the external thread 2 of the threaded spindle 1 there is a clamping nut 14, which is preferably made of plastic and, like the rotary handle 3, has a knurled handle 15 on its cylindrical outer surface.
  • This clamping nut 14 is loosely screwed onto the threaded spindle 1 and, as will be explained in more detail below, serves to clamp the mounting device fastened in the hub of a clutch disc to the multi-plate disk spring of a disc clutch of a motor vehicle.
  • two identically designed clamping sleeves 17 and 18, each consisting of four cylinder sectors 16, are loosely arranged coaxially to one another.
  • the four cylinder sectors 16 of the two clamping sleeves each comprise a quarter of the circumference. Together they enclose the two expansion cones 6, 7 and the mandrel section located between them. They consist of plastic — steel is also possible — and each have axial grooves 20 on their essentially cylindrical outer sides between axial ribs 19 in order to achieve approximately the same wall thicknesses as possible.
  • the axial ribs 19 are on their Outer surfaces each provided with U-shaped recesses 21, which together have a circumferential groove 22 for receiving an elastic clamping element 23 in the form of an rubber O-ring through which the four cylinder sectors 16 of the two clamping sleeves 17 and 18 on the expansion cylinders 6 and 7 are held together as an adapter sleeve 17, 18, on which they rest without play by means of expansion surfaces 24, which are adapted to the lateral surfaces of the expansion cones 6 and 7 in terms of their curvature and in terms of their conicity. It is important that the spreading surfaces extend at least to the axial center or to the level of the tensioning element 23, so that in any case they rest on the expansion cones 6, 7 over their entire length and cannot assume an inclined position.
  • annular metal disk 25 is arranged as a support element, which ensures that the two clamping sleeves 17 and 18, which each abut the metal disk 25 on the end face, cannot functionally influence or impair one another.
  • a disk made of hard plastic could also be used.
  • the end of the mandrel 8 provided with the expansion cone 7 is provided with a central threaded bore 26 which is open at the end and into which a centering pin 27 can optionally be screwed, which here has the form of a threaded pin.
  • This centering pin 27 in connection with a screwed centering sleeve 27 ' is used in the manner shown when the crankshaft to which the clutch disc to be installed are centered is to be provided with a corresponding end bore or with a radial bearing for receiving the centering sleeve.
  • centering sleeves 27 'of different thicknesses are available, which can optionally be placed on the centering pin.
  • the two clamping sleeves 17 and 18 each have a cylindrical outer shape of the same diameter given by the axial ribs 19 and are each freely movable on the two expansion cones 6 and 7 ensures that they, when clamped together in the hub of a clutch disc be, which takes place by appropriate tightening by means of the threaded nut 11 in the direction of arrow 28, align this property at the same time so that the axis 29 of the mandrel coincides with the hub axis. This also ensures that the clutch disc in question has an exactly right-angled position with respect to the axis 29 of the mandrel 8 and cannot be inclined to it.
  • FIGS. 3 to 6 there is also a hollow threaded spindle 1/1, which is provided at one end, like the threaded spindle 1 of FIG. 1, with a rotary handle 3 which has a knurled knurl 4 on its circumference .
  • a rotary handle 3 which has a knurled knurl 4 on its circumference .
  • an existing plastic nut 14 is loosely screwed with a knurled handle 15.
  • mandrel 8/1 with a threaded shaft 10
  • the end section opposite the threaded shaft 10 has a cylindrical extension 31 with an enlarged diameter and then has two identical and also equally directed expansion cones 32 and 33, which are at a certain axial distance from one another.
  • a single clamping sleeve 34 consisting of at least three cylinder sectors 35 is arranged on these two expansion cones 32 and 33.
  • the cylinder sectors 35 are held together on the expansion cones 32 and 33 by an annular clamping element 36 arranged in their axial center in a circumferential annular groove in the form of a rubber-elastic O-ring.
  • These cylinder sectors 35 each have two clamping surfaces 37 resting on the expansion cones 32 and 33 without play.
  • the direction is spread evenly, so that this clamping sleeve 34 is also able to align the hub of a clutch disc 41 coaxially with the axis 29 of the mandrel 8/1, i.e. to ensure that the clamped clutch disc 41 assumes an exactly right-angled position with respect to the axis 29, as is shown schematically in FIG. 6.
  • the mandrel 8/1 is also provided at one end with a concentric threaded bore 26, into which a centering pin 27 in the form of a threaded pin can be screwed, with which the mandrel 8/1 as well as the mandrel 8 of the embodiment of FIG. 1 by means of a centering sleeve 27 'can be aligned coaxially to the crankshaft axis if the bearing journal of the crankshaft is provided with a corresponding end bore or with a radial bearing 46.
  • FIG. 6 shows an application example of how an assembly device according to the invention is used to align a clutch disk 41 of a disk clutch of a motor vehicle, shown overall in dash-dotted lines.
  • the mandrel with the clamping sleeve 34 is inserted into the hub 42 of the clutch disc 41 in a completely relaxed state, so that the hub sits completely on the clamping sleeve 34.
  • the mandrel 8/1 is tightened in the direction of arrow 28 by appropriate rotation of the threaded nut 11 and the clamping sleeve 34 resting against the annular shoulder 38 of the threaded spindle 1/1 is radially expanded by the two expansion cones 32 and 33, so that they are in the Hub 42 clamped.
  • journal 47 of the crankshaft has a central bore or, shown in white, a radial bearing 46 for the gear shaft to be later stored therein
  • the centering can be done by appropriately inserting the centering pin 27 provided with a suitable centering sleeve 27 'into this bore or into it Radial bearings 46 of the journal 47 of the crankshaft take place and then the clutch housing 44 is screwed to the flywheel 45, for which purpose both parts are provided with prefabricated bores or centering pins.
  • the clutch disc 41 is only centered relative to the clutch housing 44 and clamped on the mounting device by moving the clamping nut 14 against the direction of the arrow 28.
  • the clutch housing 44 is then screwed to the flywheel 45 in its clamped state with the clutch disc 41 and is inevitably centered.
  • the expansion sleeve 34 or the expansion sleeves 17, 18 can be loosened by turning the clamping nut 11 backwards accordingly, and the mounting device can be removed from the disk coupling.
