Definitions

  • the invention relates to a grinding device designed for regrinding the brake disc of a motor vehicle disc brake, which is suitable for regrinding the worn brake disc of any type without having to disassemble the wheel hub and the brake disc.
  • a grinding device according to the introductory part of claim 1 is known from GB-A-2 085 773.
  • Such a grinding device has the advantage that the brake disc can be reground without having to remove it from the motor vehicle.
  • the two output shafts of the drive motor which is not arranged on the grinding device itself, are designed as flexible shafts, as a result of which the maximum speed of the grinding wheel is limited.
  • the speed reduction of the reduction gear for rotating the brake disc is two to one, so that it is rotated relatively quickly in comparison with the grinding wheel, which affects the machining accuracy.
  • the invention solves the problem of creating a grinding device for brake discs, with which - according to modern requirements - the repair of a worn brake disc can be carried out economically in a short time by grinding precisely to size.
  • the invention therefore provides a grinding device by means of which the brake discs can be re-ground in their installed position.
  • the grinding device is attached to the holder of the working cylinder of the disc brakes. In addition to performing the surface grinding on both sides of the brake disc, it is rotated continuously during grinding.
  • the holder 5 of the Häzylinclers the disc brake can be seen.
  • the grinding device is fastened to this holder 5 by means of a support block 19.
  • Several special bores are formed on the support bracket 19 so that the grinding device can be used universally regardless of the current position of the holder 5 and the current brake disc diameter.
  • two guide tubes 17 projecting from the support bracket 19 on both sides thereof, each for a sliding sleeve 18, are fastened, the sliding sleeves 18 being designed in such a way that they can be adjusted at four adjustment points.
  • a support frame 21 is attached to the support bracket 19, on which the drive frame 21, which is explained in detail below, is preferably attached by means of screws.
  • an adjusting screw 20 is provided which projects through a threaded hole on the support bracket 19 and is held axially fixed but rotatable in the receiving frame 21.
  • the drive 23, which is fastened to the receiving frame 21 on one side of the support bracket 19, can contain an electric motor or a pneumatic motor.
  • the drive is provided with an electric motor 22, to the output shaft 14 of which a gear is connected, which consists of gear wheels 12, 13 and a worm gear 10, 11.
  • the gear of the drive 23 is designed as a branching gear, one output shaft 15, on which a grinding wheel 16 is seated, is driven at high speed via the bevel gears 12, 13 and the other output shaft 9 is driven at low speed via the worm gear 10, 11.
  • the drive pulley 7 of a friction wheel 4 is driven, which is mounted with its shaft 3 perpendicularly to the support bracket 19 and rests on the peripheral edge of the grinding wheel 6, so that it is by means of the friction wheel 4 is continuously rotated during the grinding process.
  • the shaft 15 of the grinding wheel 16 runs perpendicular to the surface of the brake wheel 6 to be machined.
  • the grinding device can also be provided with two grinding wheels 16. An embodiment of this is shown in FIGS. 3 and 4.
  • a carriage 25 is movably mounted on the receiving frame 27 and the inner drive 24 of the second grinding wheel 16 is fastened to the carriage 25.
  • the drive 23 already known from the first exemplary embodiment is fastened to the receiving frame 27, so that the two drives 23, 24 with their grinding disks 16 encompass the brake disk 6 on both sides.
  • the adjusting spindle 28 or adjusting spindle 26 connected to the guide tube or the guide tubes 17 are used to adjust the two grinding wheels 16 against one another and with respect to the support bracket 19.
  • the other structural components correspond to those of the embodiment from FIG. 1.
  • the primary movement performs the grinding wheel 16.
  • the brake disc 6 is driven via the worm gear 10, 11 mounted on the output shaft 14, the V-belt 1 and the friction wheel 4 pressed against the circumferential surface of the brake disc 6 at the side of the grinding disc 16.
  • the drive 23 together with the grinding wheel 16, the worm gear 10, 11 and its driven pulley 8 can be implemented on the opposite side of the receiving frame 21.
  • the friction wheel 4 can also be driven from this side, it has a drive pulley 2, 7 on its drive shaft 3 on both sides of the support bracket 19, so that it can be driven by means of the belt 1 either via a drive pulley 7 or the other drive pulley 2 and the auxiliary gear of the drive 23 can be driven, which consists of the shaft 9 with the driven pulley 8 and the worm wheel 11 and the worm 10 seated on the driven shaft 14 of the electric motor 22.
  • the brake disk 6 is therefore driven during the grinding process by means of the friction wheel 4, which abuts the peripheral edge of the brake disk 6 and transmits the driving force to the brake disk 6 by friction.
  • the friction wheel 4 can also engage directly on the hub of the brake disc 6.
  • the drive 23 is adjustably attached to the receiving frame 21.
  • the grinding wheel 16 is adjusted by displacing the receiving frame 21 with the aid of the adjusting screw 20.
  • the two guide tubes 17 and the four adjustable sliding sleeves 18 are used to fix the receiving frame 21 in any position.
  • the outer surface of the brake disc 6 is machined.
  • the drive 23 is moved to the opposite side of the receiving frame 21.
  • An electric motor drive is not absolutely necessary. It can be replaced by a pneumatic motor. Furthermore, in a departure from the exemplary embodiment, a prismatic guide can be installed in the grinding device instead of the guide tubes 17.
  • the two grinding wheels 16 are set with the aid of the adjusting spindles 26, 28.
  • a movable carriage 25 is arranged on the support bracket 27, which carries the inner drive 24.
  • its inner drive pulley can be omitted.
  • the brake discs can be run without wobbling errors with a significantly smaller tolerance than with conventional technology.
  • the worn brake disks do not need to be replaced as often, so that their service life is extended.
  • the grinding device according to the invention can be constructed and manufactured with less effort and in smaller dimensions than the conventional devices of the same purpose.
  • the grinding device according to the invention is not limited to its use in special workshops, but rather it can be set up in normal workshops, so that the reworking of the brake discs can be carried out routinely with the repair work on the entire brake system.
  • the handling of the grinding device according to the invention does not require any specially trained skilled workers. Their construction is very simple and their production can be carried out using conventional, simple technology.
