Abstract

The connection is for a rigid supply (15) of a pressure medium to a housing (1). It has a pipe retainer (7) located in a housing borehole (2), which locates the pipe end (16) in the housing. The pipe retainer (8) comprises a retaining sleeve (7) in which the pipe locks, having a first locking device (11). This, and a second locking device (6) aligned to the first, locates the sleeve and pipe in the borehole. The pipe end has a radially extending flange (16) connected to the pipe (15), which is aligned to a recess (13) cut in the inner surface of the retaining sleeve. USE/ADVANTAGE - For connection of brake pipe to brake housing, easy to assemble, avoids pipe and housing being in direct contact to reduce vibration transmission.

Description

The invention relates to a connection of a rigid line to a housing. Such a connection is for example necessary to attach a brake line to a brake housing close. Such connections are for example in the brake manual, 9th edition, Bartsch-Verlag, in particular p. 271. This is done with a flare provided tube held by a union nut, which with the internal thread of a hole in the to be connected Housing is screwed.

Such connections are very complex to assemble because the following activities must be carried out in succession sen: insert the tube into the hole, screw the Union nut, applying the torque required for screwing in is necessary and application of a Tightening torque to secure the screw connection.

The invention therefore assumes a connection to the genus resulting from the preamble of claim 1.

The object of the invention is such a connection to make assembly easier. Additional tasks of the Invention are to prevent that from preferably  Metal existing rigid pipe directly on the in the Re Gel made of steel is applied to the transfer reducing acoustic vibrations.

The task is characterized by the distinctive Part of claim 1 resulting combination of features solved. The invention is in principle, instead of be Known union nut snaps into the housing bore bare retaining bush to provide, the rigid tube in the Retaining bush and this in turn snapped into the hole becomes.

A particular advantage with regard to the invention receives one in that the holding bushing from an acoustic Vibrations little to the pipe-transmitting material is made. On the one hand, the material must be so ela be static that it snaps the tube against the Retaining bushing and again the holding bushing opposite the Ge houses allowed. On the other hand, the material has to be so firm be that the resulting from the pressure transfer in Forces acting axially through the holding tube socket to be taken safely, so that by such Forces neither the retaining bush from the housing bore nor the pipe can be torn from the holding bush.

A particularly firm mounting of the pipe in the holding bush is obtained from the characteristic part of the Claim 2 resulting combination of features. The one described Snap the flared pipe end into the retaining bush sets an elasticity of the holding bush compared to the star ahead of the pipe end. Such elasticity can be comparatively simply with those listed in claim 3  To achieve funds. However, it is not mandatory necessary that the slots abge on that of the recess turned end of the holding bush are open. The one to the leading tube-pointing end section can also be available in girth direction connected continuously, as far as only secure is that the opening provided for the tube in the Holding bush is far enough. Otherwise you can namely the pipe because of the lack of elasticity of the bushing in the Do not insert this area into the inner opening of the socket Ren. Below are advantages for the case wrote that towards the pipe to be inserted end of the retaining bushing has a continuous loop forms the ring and thus be sufficiently rigid sits (outside hexagon).

Around the holding bush in to be able to easily snap into the housing bore, recommend the features resulting from claim 4. There with can hold the bushing by simply pressing in with the pipe provided pipe holder in the housing bushing duration be held in custody.

To detach the retaining bush from the housing bore to facilitate, we recommend the features according to claim 5. This makes it possible to remove the retaining bush from the housing bore unscrew.

The retaining bush snaps into the housing bore simplify in particular that the Claim 6 resulting funds are applied. After that are the circumferential protrusions are essentially reflected provided hook-shaped cross section. This will make the  Projections due to the rotation that occurs during the pressing moments and the elasticity caused by the slits tilted a little towards the hole entrance to press in of the retaining bush in the housing bore. Before Partially, about two win are used in the holding bush with the corresponding recesses in the housing bore tion.

To manufacture the bore and thus the connection facilitate the application of the features according to claim 7 recommended. Then the housing bore can be easily Make way as a stepped bore.

An appropriate distribution of the individual holes The functions to be performed result from the Combination of features according to claim 7.

A particularly good seal but also with the corresponding Material, good acoustic damping between the pipe end and the housing can be viewed in claim 8 Achieving the combination of features listed in the retaining bush chen.

It can be between the end of the pipe and the floor the stepped bore in the housing bore sealing ring have the simple structure described in claim 9.

In the housing, it seals particularly well to get the hole, it is recommended to use the Merk Painting combination according to claim 10 the sealing ring for the seal between the outlet of the Pressure medium line and the side walls of the stepped bore, especially towards the exterior of the housing.  

To make it easier to unscrew the retaining bush, em recommends the combination of features according to claim 8. By the hexagon thus formed can be easily the retaining bush from the thread in the housing bore unscrew as far as this is desired for disassembly purposes.

An improvement of this dismantling measure, but also one additional protection against tearing out the enclosed NEN tube with or without a holding bush from the housing achieved by using the features of claim 12 chen.

To the necessary elasticity, but also rigidity for Reaching the pipe holder is recommended with regard to the materials for the retaining bush or the sealing ring and / or expansion ring the combination of features according to claim 13. Overall, the combination according to claim 14 proven by the sealing ring, retaining bush and expanding ring have different elasticities, namely in the ge named order with decreasing elasticity.

With regard to the assembly of both the line fastening and their dismantling is also recommended in further training Invention the steps according to claim 15 and 16 respectively.

An embodiment of the invention is described below hand of the drawing explained. In it shows

Fig. 1 shows a connection according to the invention and

Fig. 2 is a component of the terminal of FIG. 1.

In Fig. 1, a section of a cut ausgebestell th housing 1 is shown, which has a housing bore opening from the outside into the Ge Ge stepped bore 2 . A first bore section 3 , a second bore section 4 and a third bore section 5 can be seen in the drawing.

The first bore section 3 has a spirally wound recess 6 as an internal thread. Instead of this self-contained recess 6 , however, a plurality of annular recesses arranged one behind the other can be vorgese hen.

In the drawing, a holding bushing 7 is shown on both sides of its median plane in two different installation positions. The holding bush 7 has an outer Buchsenab section 8, a central bushing section 9 and a neren bushing section 10th The outer socket section 8 is formed as a circumferential bracket and has six surfaces which are at an angle to one another and which form a hexagon. The middle socket section 9 is provided with sawtooth-shaped projections 11 , which are assigned to the recesses 6 in the housing 1 . These projections 11 can accordingly represent a continuous external thread, as shown in the drawing, but can also run individually in a ring around the central bushing section 9 and thus provide a rest possibility with the correspondingly shaped recesses 6 .

The holding bush 7 has a conical inner bore 12 which merges into an annular recess 13 . This has an essentially dome-shaped contour.

In the longitudinal direction on the lateral surface of the conical inner bore 12 , longitudinal slots 14 are distributed at a uniform distance, which penetrate the retaining bush 7 . These longitudinal slots extend from approximately the center of the ring recess 13 in the inner socket section 10 to approximately the center of the outer socket section 8 . In the upper part of the drawing you can see an end portion of a tube 15 which has a flange 16 at its lower end in the drawing. In the right part of the drawing, the flange 16 is snapped into the ring recess 13 .

The inner sleeve portion 10 is limited by a sealing ring 17 which is integrally formed on the holding bush 7 . This can be done by vulcanizing, gluing or by casting. The sealing ring 17 is preferably made of a softer elastic material than the holding bush 7 in order to achieve an improved sealing effect. Furthermore, the material of the sealing ring should transmit as little sound waves as possible. An additional acoustic damping is achieved by the separating layer formed between the sealing ring 17 and the housing 1 , which partly reflects sound waves and thus ensures a damped transmission of these waves.

From the drawing, an expanding ring 18 can also be seen, which consists of two conical sections that reinforce towards the center of the ring 18 . The lower ring section 19 exerts a wedge effect. The third bore section 5 of the stepped bore 2 leads into the interior of the housing 1 , which can be the housing of a disc brake, for example, but also a master cylinder, controller or other device of a brake system.

The connection according to the invention is now assembled as follows. In the removed state of the holding bush 7 , the flange 16 of the tube is shifted towards the lower section 10 of the book. Although the inner bore 12 tapers conically in this direction, insertion of the flange 16 is nevertheless possible, since through the longitudinal slots 14 the middle bushing section, but also parts of the outer and inner bushing sections, are deformable in the radial direction. The elasticity of this bushing section increases as a function of the number of slots and their width, so that the elasticity can be determined by the width of the webs located between the slots. The same applies to the selection of the sleeve cross-section.

After the flange is 16 jack in the annular recess 13 of the holding engaged 7, which assumes the position shown on the left side of the drawing, the holding sleeve 7, together with the tube 15 with detent fenbohrung 2 pressed into the Stu. This can preferably be done by a radial force exerted on the end face of the outer bushing section 8 . But it is also possible that by an axial force exerted on the pipe 15 , the latched into the holding bushing 7 takes the holding bushing 7 from the position shown on the left side of the drawing into the position shown on the right side of the drawing. Here, in turn, the resilient action of the slots 14 allows movement of the projections 11 or the thread formed by them in the axial direction along the he most drilling section 3 . The Außenum catch of the projections 11 is reduced by the force exerted by the bore wall on the inclined flanks 20 , so that the projections 11 can penetrate into the stepped bore 2 .

As soon as the holding bush 7 reaches its position shown on the right-hand side of the drawing, the projections 11 correspond to corresponding recesses 6 in the housing 1 , so that the middle bushing section 9 can expand again and the projections 11 penetrate into the recesses 6 . The desired detent is achieved in this way. The we essential horizontal rear flanks ensure that a large force can be exerted in the axial direction outwards from the holding bush 7 to the housing 1 without the holding bush 7 tearing out of the bore 2 .

To further reinforce this effect, the expansion ring 18 can be moved in the axial direction along the tube 15 in the drawing downward, so that the ring portion 19 a wedge action between the tube 15 and the middle Buchsenab section 9 unfolds and so the holding effect of the holding bush 7 in the bore 2 reinforced. In this position, the sealing ring 17 lies sealingly on the conically inclined bottom 22 of the second bore section 4 . But there can also be a gap here, so that the seal is achieved by an axially extending circumferential sealing surface 23 of the sealing ring 17 with respect to the lateral surface of the second bore section 4 . The sealing surface 23 must protrude from the outer surface of the lower bushing section 10 .

In order to remove the connection of the pipe 15 to the housing 1, one attacks with a wrench on the hexagon of the outer bushing section 8 and rotates it about the longitudinal axis of the bushing 7 . Due to the thread shape of the recesses 11 and the associated recesses 6 , the bushing 7 is screwed out of the bore 2 in this way. The se effect is supported by the ring portion 19 of the expansion ring 8 , which prevents the central Buchsenab from giving in radially inward and thus supports the screwing movement. After unscrewing the holding bush 7 , the flange 16 can be disengaged from the ring recess 13 by pulling in the axial direction. The present invention is ideally suited to hinder the transmission of sound waves via the brake line system. These sound waves emanate particularly from some components of a regulated braking system, such as a high-pressure pump, switching valve regulators and other devices. Since the holding bush fully encompasses the end of the line and thus prevents an acoustic bridge between the housing and the line, such sound waves can only be transmitted to a limited extent from the housing in question to the line. However, the prerequisite is that the holding bush is made of a material that dampens the propagation of sound waves.

For the rest, the separating layers between the under act different materials between the steel of the casing ses, the plastic of the holding sleeve and again the steel of the brake pipe as reflective surfaces for the acu static sound waves, so that their propagation here too is hindered by.

Fig. 2 shows a spatial representation in a different dimension rod the expansion ring 18 , which is provided for radial mounting on the tube 15 with a continuous slot 25 .
