Definitions
- Hose coupling especially for high-pressure hydraulic lines of a release system
- the invention relates to a hose coupling, in particular for high-pressure hydraulic lines of a release system, as it finds application for example in a clutch system of a vehicle.
- a hose coupling which comprises a hose nipple, which one or more annular serrated
- undercuts which produce a positive connection with a pushed onto the hose nipple hose.
- the inner diameter of the tube is slightly smaller than the outer diameter of the undercuts.
- the hose nipple is pressed into the tubing of small dimensioned diameter, so that the inner wall of the tubing is plastically and / or elastically deformed, whereby simultaneously sealed and a tight fit is achieved.
- Such a connection is also called Christmas tree connection.
- a simple compression sleeve is pushed at least in some areas of the hose nipple and squeezed onto the hose and the hose nipple by means of one or more, in the present embodiment, two annular notches.
- Such a connection is also referred to as crimp connection.
- the compression sleeve is made of a plastically deformable metal and is inserted to make the connection over the end of the hose.
- the hose with the press sleeve arranged thereon is then pushed over the hose nipple to a boundary collar.
- one or more annular notches are introduced, is pressed by the notches, the hose located in this area on the hose nipple and elastically and / or plastically deformed.
- the other end of the hose is with a plug also by means of a
- the object of the invention is therefore to provide a reliable hose coupling which withstands axial forces.
- the hose coupling uses a connection element for the hose in the form of a hose nipple, which is connectable to a hose line to which a compression sleeve is used, which pushed over the hose in the connection area with the hose nipple with a first diameter range and squeezed by means of one or more first indentations (crimping) and wherein the hose nipple additionally has a fastening region which adjoins the connection region and wherein the compression sleeve has a second diameter region which can be pressed axially fixed onto the fastening region of the hose nipple.
- the second diameter range of the compression sleeve is compared to the first
- Diameter range is preferably reduced and engages over at least a first collar of the hose nipple and is pressed axially fixed behind this by means of one or more second indentations by crimping (crimping) on the hose nipple.
- the hose nipple may have a second collar at a distance from the first collar, so that a groove is formed between the two bands.
- the second diameter region of the compression sleeve then extends axially over the two collars and is squeezed in the attachment region between the first and the second collar by means of one or more second indentations and thereby axially fixed between the first and the second collar.
- the first and / or the second collar in the manner of a diameter extension radially outward, but it is also possible to provide in the hose nipple one or more notches, through which one or more grooves with collars (stops) are formed, between which the second diameter portion of the compression sleeve is attached by notching (crimping).
- the hose nipple may have a substantially cylindrical shape in the connection region to the hose line on the outer contour or even as previously a fir-tree-like stepped shape.
- the hose nipple need not be formed separately but may also form the end of a fitting (e.g., the end portion of a steel feed pipe) for the hose or may be attached to a body to which the hose is to be connected.
- the compression sleeve consists of a plastically deformable metallic pipe section, wherein the second diameter range is generated by a radial diameter reduction of the pipe section.
- the first collar of the hose nipple forms a boundary collar and thus a stop for the provided with the sleeve end of the pushed hose, so that it can be securely fixed axially in the compression sleeve and on the hose nipple and then fastened by crimping.
- FIG. 2 shows a compression sleeve in longitudinal section
- FIG. 3 shows the end of a hose line to be connected to the hose nipple;
- FIG. 4 shows the compression tube inserted into the tubing,
- Figure 6 shows the connection made between hose nipple and hose in longitudinal section
- FIG. 1 shows a hose nipple 1 for the hose coupling according to the invention, which, unlike known hose nipples, has a connection region 1.1 with an outside diameter D1.1, which is essentially cylindrical and without a so-called "fir tree geometry", and the hose is soft (FIG. 3).
- D1.1 outside diameter
- D1.1 outside diameter
- FIG. 3 Connected to the connection region 1.1 is a first radially outwardly pointing first collar 2 and, at a distance a, a second radially outwardly pointing second collar 3.
- the first and the second collar 2, 3 have an outer diameter D1.2 and The first radially outwardly pointing collar 2 forms a boundary collar in the direction of the connection region 1.1 for the hose line which is to be pushed onto the connection region 1.1 ( Figure 3)
- the hose nipple 1 with an outer diameter D1.3 continues to run substantially cylindrically. Through the hose nipple 1 extends a central fürstr mö réelle. 4
- the compression sleeve 5 has according to Figure 2 in the not yet connected state in the
- the inner diameter d7 is designed so that it can be pushed over the outer diameter D1.2 of the first and second collar 2, 3 of the hose nipple 1.
- a shoulder 8 which forms a stop for the insertable into the compression sleeve 5 end of the hose line ( Figure 3) extends.
- the first diameter region has a radially outwardly bent edge region 9, which favors the insertion of the hose line (FIG. 3).
- an end of the hose 10 is shown, which consists of compressible plastic and has an inner diameter d10, which corresponds to the outer diameter D1 of the hose nipple 1 and thus is slidable over this.
- the outer diameter D10 of the hose 10 corresponds to the first inner diameter d6 of the first diameter portion 6 of the compression sleeve 5 and is inserted into this.
- the hose 10 is first inserted according to Figure 4 in the first diameter portion 6 of the compression sleeve 5 until it rests with its end against the stopper 8. Now, the compression sleeve 5 is pushed with the tube 10 therein via the hose nipple 1 via its connection areas 1.1 until the second diameter portion 7 of the compression sleeve 5 surrounds the first collar 2 and the second collar 3 of the hose nipple 1 ( Figure 5).
- the first collar 2 forms a boundary collar for the hose 10.
- the length b of the second diameter portion 7 is chosen so that this axially protrudes slightly above the second collar 3.
- the compression sleeve 5 and the hose 10 have been positioned relative to one another in the required joining position, the compression sleeve is now peripherally attached to the compression sleeve 5 in a first position P1 and axially spaced apart at a second position P2 a diameter reduction by crimping (crimping), whereby according to Figures 6 and 7, the compression sleeve 5 formed in the diameter portion 6 at the positions P1, P2 in the material of the hose 10 and thereby pressed them firmly on the connection portion 1.1 of the hose nipple 1.
- the invention provides a simple and fail-safe hose coupling, in which for the first time a compression sleeve 5 (crimp sleeve) with two different crimping sections is used, wherein a crimp section (first diameter section 6) of the compression sleeve 5 fixes the flexible hose line 10 (hydraulic line on the end section of FIG Steel supply line (hose nipple 1) and the second crimping section (second diameter portion 7), the axial attachment of the compression sleeve 5 directly on a crimping the steel supply line in the form of the hose coupling 1 realized by pressing.
- a compression sleeve 5 with two different crimping sections
