Definitions

  • the invention relates to a device for attaching a rubber elastic Bellows on a roll-off stamp of a vehicle air suspension.
  • Air bellows for automotive air suspension are made of rubber-like material, which is generally reinforced with embedded nylon threads. Because of the constant suspension movement of the bellows on their unwinding stamp they are subject to natural wear and tear that eventually leads to tearing or bursting. The bellows usually have to be on site be changed by the truck driver because the vehicle is sitting on and slanted.
  • the object of the present invention is to provide a tool that makes the air bag easy and be attached to the roll-off stamp without risk of damage can.
  • the tool should be simple, inexpensive Stand out so that it can be used in small workshops and can be used by the forwarding agents themselves and possibly even can be taken in the truck.
  • the device has a counter-stamp on the one opposite the roll-off stamp Bellows attacks and aligned approximately coaxially to this is that roll-off and counter-stamp relative in the axial direction are movable towards each other and lie close to the bellows ends, so that the stamp in the interior of the bellows while moving together an overpressure can be generated.
  • the counter-stamp will both the bead ring of the air bellows in the groove provided on the roll-off stamp brought as well as the subsequent cylindrical part of the Air bellows forming the desired ring bead over the roll-off bellows pushed. It is essential that the air bellows is sealed is, so that one from the side opposite the roll stamp of the air bellows exerts a force on the opening at the roll-off ram of the bellows can exercise.
  • this is sufficient by moving the Stamp in the bellows generated overpressure to attach, even more reliable and the method is suitable for different air bellows however, if the device has an air connection to generate an additional one Has overpressure in the bellows.
  • this air connection can for example a compressed air line or a compressed air tank connected how it is used to inflate tires. Thereby will widen the bead ring and snap it into place the roll-off stamp very easy.
  • the air connection is expediently arranged on the counter stamp and has a valve so that the air does not escape unintentionally can.
  • For venting the bellows after attaching it to the unwinding stamp is on the device a combined with the said valve or separate air outlet provided.
  • a guide for at least one punch in the axial direction have so that this stamp can not break out laterally.
  • the drive of the stamp can also be correspondingly be stable.
  • the movable stamp (s) in the partially collapsed Condition on the device can be locked, the drive for the process of stamping smaller and therefore cheaper be carried out. Then you need the drive only to build up a sufficient form in the bellows for sealing. Then the stamp is locked on the device and there are 5 - 6 bar compressed air is admitted through the air connection until the bead ring in the groove slips.
  • the device should be adjustable accordingly, which is indicated by a Adjusting the stamp itself, its holder on the device, or the drive connected to the stamp is possible. This is guaranteed, for example, if at least the starting position of a Stamp in the axial direction in different stroke positions on the Device, in particular the guide, can be locked.
  • the counter stamp is preferably conical, so that it for sealing and centering the bellows in the assigned bellows opening can immerse. Furthermore, it can be an easily replaceable one Element so that stamps for bellows with different openings can be used, the contour of each of the bellows opening is adjusted. Finally, the counter-stamp within the scope of the invention also be made in several parts.
  • the drive for moving the stamp relative to each other can either manually via a power transmission or via a motor Drive, in particular a cylinder-piston unit, take place.
  • the inventive Device at least two extending laterally of the bellows Perform on that drive at one end, at the other end Support one of the stamps, these strips at the same time can serve to guide the movable plunger axially.
  • Figures 1-3 show a side view the device in different stroke positions, the air bellows is shown in section.
  • a rubber-elastic bellows 1 can be recognized by a roll-off stamp 2.
  • Bellows 1 and roll stamp 2 are commercially available Air suspension components of a truck.
  • the bead ring 3 of the air bellows 1 lie in the groove 4 of the rolling die 2, as shown in FIG is.
  • the invention Device of the rolling stamp 2 on the cylinder axis the air bellows 1 arranged.
  • the counter stamp 5 is also located on the cylinder axis, but on the opposite side of the air bellows 1.
  • the counter-punch 5 has a conical shape towards the air bellows 1 converging end, which in the assigned to the counter stamp 5 Opening of the bellows 1 is inserted and so this opening seals and reliably guides the air bag 1.
  • Roll-off stamp 2 and counter-stamp 5 are made by a cylinder-piston unit 6 pushed together. This is done in the exemplary embodiment Hand lever 7 operated. But just as well is a foot pedal or a motorized hydraulic or pneumatic pump is suitable.
  • the unwind stamp 2 is simply placed on a plate 8, which is on End of the piston rod of the vertically aligned cylinder-piston unit 6 is located.
  • the plate 8 optionally has a centering aid for a quick positioning of the roll-off stamp 2. This Centering aid is expediently designed so that it can be used for centering of roll stamps of different dimensions, in particular different diameter, serves.
  • the plate 8 is moved up together with the rolling stamp 2; it is in the form of lateral projections 8a in axial guides guided by vertical strips 18.
  • the air bellows 1 tensions between the unwinding stamp 2 and the stationary counter-stamp.
  • the device has an air connection 10, via which from a tire inflator or an operating compressed air line additional air is pressed into the interior of the air bellows 1 can be as soon as its openings close enough Unroll roll 2 and counter-punch 5.
  • the air connection 10 is arranged on the counter punch 5 and with a compressed air line 11 a check valve 12 connected to the air inlet. In the area of Check valve 12 is still a pressure relief 13 with silencer 14 and a pressure gauge 15 is arranged.
  • Air bellows 1 and unwind ram 2 are now ready for installation:
  • the bead ring 3 is tight in the groove 4 and the bellows 1 is through its rolling on the stamp 2 is shortened sufficiently to be problem-free used in the space provided for this purpose in the vehicle suspension to be able to.
  • the air bellows 1 is pushed onto the unwinding stamp 2 then as follows: Roll-off stamp 2 and counter-stamp 5 are only so moved far together until the bellows 1 is sufficiently close to both is present.
  • the jack 6 is with a weight of about 1 to acted upon.
  • the retaining pins 21 in immediately below the Overhangs 8a holes 22 are inserted and the jack relieved, the projections 8a lowering on the retaining pins.
  • the bellows 1 over the air connection 10 with an overpressure of 2 - 8 bar, in particular 5 - 6 bar, applied, whereupon the bead ring 3 snaps into the groove 4 of the rolling punch 2.
  • the illustrated embodiment contains the device in addition to the elements already mentioned Frame 9, which consists of an upper plate 17, a lower plate 19 and several strips 18 connecting them.
  • Frame 9 On the plate 17 is the Counter stamp 5 attached so that it easily against alternative counter stamp is interchangeable, the dimensions of the openings of others Air bellows correspond.
  • the strips 18 are in shape, for example executed by U-profiles so that they form a guide for the plate 8.
  • the cylinder-piston unit 6 is also attached to the frame 9, and four rollers 20 on which the entire device can be moved in the workshop. Finally, the frame 9 a rear fender 16 on.
  • the invention has the advantage that air bellows are very simple and can be easily installed on roll-off stamps, whereby both aspects of attaching, snapping the bead ring into the groove and the rolling of the air bellows on the stamp, in one can be carried out in a single operation.
