Definitions

  • the invention relates to a pressure medium cylinder with a longitudinally slotted cylinder tube which is closed at the end, in which a sealed piston is guided so as to be longitudinally displaceable and the longitudinal slot of which is sealed on both sides of the piston by an internal flexible sealing tape which is located in a pressure-free area of the piston between two piston / cylinder seals a force transmission element protruding through the longitudinal slot and directly connected to the piston is passed, the force transmission element being guided longitudinally on at least two parallel guideways of an external parallel guide by means of a bow-like guide part partially encompassing the cylinder tube, the guideways of which on both sides of the longitudinal slot are directly on the outside of the cylinder tube are arranged.
  • Such a pressure medium cylinder is characterized in that the force transmission element, depending on the respective application, transverse forces or moments occurring can take up because the force transmission element is supported on the guideways.
  • the guide tracks lying on both sides of the longitudinal slot on the outside of the cylinder tube also prevent, in cooperation with the bow-like guide part which partially surrounds the cylinder tube, an undesirable widening of the longitudinal slot of the cylinder tube which occurs at high internal pressures.
  • the guidance of the power transmission element through the two parallel guideways of the external parallel guide must have a certain play for reasons of ease of movement. This means that the force transmission element can carry out a small limited tilting movement with respect to the cylinder tube axis under the action of transverse forces or moments, or it also suffers a certain elastic deformation under very high loads. Since the flexible sealing tape sealing the longitudinal slot, as mentioned at the outset, is lifted off the longitudinal slot in the unpressurized area between the two piston / cylinder seals, the two piston cylinder seals must have a certain axial minimum distance, which in turn means that the overall piston length has a certain minimum value cannot fall short.
  • the object of the invention is therefore to remedy this and to create a pressure medium cylinder with a longitudinally slotted cylinder tube which is closed at the end and which is largely independent of the load-dependent slight tilting movements of the force transmission element or of small, operationally occurring deflections of the cylinder tube.
  • the pressure medium cylinder mentioned at the outset is characterized according to the invention in that the piston has two pistons arranged on both sides of the power transmission element and at least one each Has piston / cylinder seal carrying piston parts and that the two piston parts are connected to the power transmission element with limited radial movement.
  • the force transmission element is guided perfectly with very little play by means of the parallel guide on the outside of the cylinder tube.
  • the piston itself can achieve a tolerance compensation with respect to the inner wall of the cylinder tube and can always adjust itself so that no lateral forces are exerted on the piston / cylinder seals.
  • the piston is therefore self-centering. With slight deflections of the cylinder tube, it can adapt itself to the curvature of the cylinder tube without losing its self-centering.
  • the longitudinal slot of the cylinder tube experiences a certain widening, albeit a very small one, but one that does exist, which leads to a corresponding change in shape of the cross section of the cylinder tube bore. Since the two piston parts are connected to the force transmission element in such a way that they can move in a radially limited manner, the soft piston / cylinder seals can adapt to this change in shape without being hindered by a rigid piston.
  • the two piston parts each consist of plastic material.
  • the pins arranged on the two piston parts can be connected coaxially to one another; however, the arrangement can also be such that the two piston parts are connected to one another by an integral pin.
  • the axial coupling of the two piston parts with the force transmission element can be brought about in a simple manner in that the two piston parts are each axially supported via a shoulder against the force transmission element engaging between them.
  • the pin or the pin can be connected to the force transmission element via at least one transverse pin penetrating the receiving opening, the transverse pin running with a corresponding clearance either through a corresponding transverse bore of the pin or pins, or arranged so as to engage in an open transverse groove of the assigned pin is.
  • the pins or the pin can be positively connected to the force transmission element via at least one coupling device with lugs of the other part engaging in corresponding recesses in one part.
  • the force transmission element is fork-shaped, at least in the area of the receiving opening, with two legs laterally delimiting the longitudinally slotted receiving opening, as a result of which manufacture and assembly are simplified, while the flexible sealing tape is guided directly through the receiving opening and is simply inserted laterally into the latter can.
  • the pressure medium cylinder shown in FIG. 1, 2 has a cylinder tube 2 containing a cylindrical cylinder bore 1, the cylinder bore 1 of which is closed at the end by two covers 3 screwed to the cylinder tube 2.
  • One of the fastening screws is visible at 4 in FIG. 1.
  • a piston 5 is guided in a longitudinally displaceable manner and is directly connected to a force transmission element 6, which is guided to the outside with a web-like part 7 through a longitudinal slot 8 of the cylinder tube 2.
  • the force transmission element 6 is integrally formed with the cylinder tube 2 partially encompassing bow-like part 9 of substantially U-shaped cross-sectional shape, the two legs 10 of which each carry a guide bar 11 on their inside.
  • the guide strips 11 are guided on both sides of the longitudinal slot 8 directly on the outer wall of the cylinder tube 2, with parallel cross-sectionally triangular guide tracks 12.
  • the guideways 12 are arranged in the area between the outer edge of the longitudinal slot 8 and the plane of symmetry containing the piston axis and running at right angles to the longitudinal slot 8, which is indicated at 13.
  • the longitudinal slot 8 is sealed on both sides of the piston 5 by an internal, flexible sealing tape 14 which is anchored at the ends to the covers 3 and which is guided in the region of the piston 5 under the web-like part 7 of the force transmission element 6.
  • This area is located between two axially spaced from one another on the piston 5 arranged piston / Zylinderdichtun q s in the form of soft sealing collars 15. It is depressurized, so that the longitudinal slot 8 in this area for the passage of the web-like member 7, as shown in FIG 1 can be opened without loss of pressure medium.
  • the sealing tape 14 seals the longitudinal slot 8 on both sides of the piston 5, so that when a pressure medium, for example compressed air, is applied to the cylinder bore 1 via pressure medium channels 18 provided in the covers 3, the piston 5 executes a corresponding longitudinal movement in the cylinder bore 1 .
  • a pressure medium for example compressed air
  • the force transmission element 6 then has on the web-like part 7 a fork-shaped part 20, the two legs of which laterally delimit a longitudinally slotted receiving opening 21, through which the sealing tape 14 is simultaneously passed.
  • the inner wall of the receiving opening 21 is partially cylindrical (Fig. 2); in the area of the sealing tape 14, it is provided with a groove-like depression which receives the sealing tape 14.
  • the piston 5 has two piston parts 22 arranged symmetrically on both sides of the fork-shaped part 20 of the force transmission element 6 on, each made of plastic material.
  • a sealing sleeve 15 is inserted, while a frustoconical cross section 24 adjoining the cylindrical section 23 ends in a shoulder 25, via which the respective piston part 22 axially against the forked part 20 of the Power transmission element 6 is supported.
  • a damping bore 250 which ends axially in each of the piston parts 22 and is closed at one end, in the end position of the piston interacts with a damping tube 260 in the manner shown in FIG. 1.
  • the two piston parts 22 are each fastened to the fork-shaped part 20 of the force transmission element 6 in a radially limited manner.
  • the arrangement in the embodiment according to FIGS. 1 to 3 is such that the two piston parts 22 each carry a coaxial projecting cylindrical pin 26 in the region of the shoulder 25, which with play in the part-cylindrical receiving opening 21 of the fork-shaped part 20 are plugged in.
  • the two piston parts 22 are axially connected to the fork-shaped part 20 by two transverse pins 27, which have the receiving opening 21 and corresponding transverse bores 28 penetrate into the pin 26.
  • the arrangement is such that the two coaxial pins 26 of the piston parts 22 each have an end in the form of an annular collar 30, while the optionally two-part fork-shaped part 20 with an annular groove 31 in the area its two legs are provided, in which the two ring collars 30 engage, so that together with the support of the shoulder 25 of the piston parts 22 on the fork-shaped part 20 a positive connection of the two piston parts 22 with the force transmission element 6 is achieved.
  • the already mentioned limited radial mobility of the two piston parts 22 is ensured by appropriate dimensioning of the annular groove 31 and the partially cylindrical receiving opening 21, as well as the diameter of the cylindrical pins 26.
  • the two piston parts 22 are connected to one another by a one-piece pin 26a integrally formed on both piston parts 22, which is connected to the fork-shaped part by a transverse pin 27 penetrating a transverse bore 28 in a manner which basically corresponds to the embodiment according to FIG 20 of the power transmission element 6 is also connected in a radially limited manner.
  • the arrangement in the 6 can also be taken in such a way that the two cylindrical pins 26 of the piston parts 22 are designed to be connectable to one another at the end.
  • one pin 26 carries, for example, a threaded connector 32, while the other pin 26 is provided with a corresponding threaded bore 33.
  • latching connection elements can also be used.
  • the two piston parts 22 are in this case axially coupled to the bow-shaped part 20 in that they are supported laterally on the fork-shaped part 20 with their annular shoulder 25, so that the pins 26 which are connected to one another act as tie rods.
  • the cross pin 27 could also be omitted in the embodiment according to FIG. 5.
  • the cylindrical pins 26 of the two piston parts are each provided with a transverse groove 34 which is open at the edge and into which a transverse pin 35 which penetrates the partially cylindrical receiving opening 21 of the fork-shaped part 20 engages.
  • a limited one radial mobility of the piston parts 22 with respect to the fork-shaped part 20 and thus the force transmission element 6 is guaranteed.
  • the pins 26 are each provided on the piston parts 22.
  • the arrangement could also be reversed, in that laterally projecting coaxial pins are arranged on the force transmission element 6 in the cylinder bore 1, on which the piston parts with a corresponding receiving opening are then placed with limited radial play but axially immovable.
  • the piston parts 22 carrying the sealing sleeves 15 are mounted with limited radial movement with respect to the force transmission element 6, the piston parts 22 with their sealing sleeves 15 are self-centering in the cylinder bore 1, and their setting cannot be impaired by tilting movements of the force transmission element which are possible within the tolerance range .
  • the piston parts 22 with their sealing sleeves 15 can adapt to the shape of the cylinder bore 1 without being impeded by rigid piston parts, which is particularly important when a certain deflection occurs in a long cylinder tube 2 or the longitudinal slot 8 experiences a certain small widening under the action of the pressure medium acting on the cylinder bore 1.
