Problems solved by technology

During the extrusion process, tensile loads of the inner hose relative to the hose body can occur, which can lead to microcracks in the inner hose, whereby the tightness of the connection to the high-pressure line is no longer guaranteed

Embodiment Construction

[0026] The coupling part 1 chosen as an example comprises a connecting head 2 on which pressing means 3 are formed. The coupling part 1 is provided with a through hole 11 along its longitudinal center axis.

[0027] The connection head 2 has a conically widened plug part 21 which is provided with a groove 211 for accommodating the sealing ring 22 . A collar 23 with an enlarged diameter is coupled to the plug part 21 , by means of which collar a stop 231 is formed. The collar 23 is provided on its side opposite the stop 231 with a bevel 24 to which the cylindrical section 25 is coupled. The cylindrical section 25 is provided with a groove 251 for accommodating the snap ring 26 . The connection head 2 accommodates a union nut 4 which rests against the bevel 24 and is held axially in a loss-proof manner by a snap ring 26 .

[0028] The extrusion joint 3 is substantially formed by a holding section 31 to which a first profile section 32 and a second profile section 33 are attac...

Abstract

The invention relates to a coupling part (1) for a hose coupling, in particular for a high-pressure hydraulic line, comprising a connection head (2) for connecting to a fitting and a press-fitting head (3) formed thereon for receiving a hose end section (6), the invention relates to a press fitting (1) for a hose end section (6), to which a pushed hose end section (6) can be fastened in a press-fit manner by means of an at least partially sleeve-shaped press frame (5) surrounding the hose end section, and which press fitting has a rib-shaped profile comprising ribs defined by grooves, the rib-shaped profile has at least two profile sections (32, 33), the recess (323) of the first profile section (32) facing the connector (2) having a symmetrical cross-section and the recess (332) of the second profile section (33) having an asymmetric cross-section, and wherein the recess (323) of the first profile section (32) facing the connector (2) has a symmetrical cross-section and the recess (332) of the second profile section (33) having an asymmetric cross-section. The recess (332) of the second profile section (33) has a larger recess volume than the recess (323) of the first profile section (32). The invention also relates to a hose coupling having such a coupling part (1).

Description

technical field [0001] The invention relates to a coupling element for a hose coupling, in particular for a high-pressure hydraulic line, according to the preamble of patent claim 1 . The invention also relates to a hose coupling according to patent claim 13 . Background technique [0002] A coupling element for high-pressure hydraulic lines is known from German utility model DE 20 2004 008 126 U1. The coupling element comprises a tubular connecting socket with a hose connection and means for coupling to a fitting. A hose holder in the form of a rib-shaped profile is provided on the hose connection. The high-pressure hoses used are generally multi-layered and contain metal inserts, which are necessary for high-pressure applications, in a known manner. For assembly, the hose connection of the coupling element is pushed into the inner hose of the high-pressure hose to be fastened. The rib-like profile then prevents the hose from being pulled out easily. At the same time a...
