- the invention further relates to a corresponding hydraulic system.
- connection arrangement for example, as a plug connection arrangement from DE 10 2007 003 048 A1.
- This shows a connector assembly for connecting pressure lines of a hydraulic system, with a connector, a plug-in connector in this connector, a sealing element for sealing the inserted into the socket connecting piece and a transversely mounted to the insertion direction securing spring to secure the connection against accidental release, wherein the securing spring is U-shaped and engage the legs of this U-shape in the mounted state of the locking spring in recesses of the connector socket and abut against a stop of the inserted connecting piece.
- a fuse is required which is able to withstand occurring forces and vibrations.
- the clip has two elastic legs, which are spaced apart from each other so that they are first bent apart when mounted on the connecting piece against the spring force to be then pressed by means of the spring force to the periphery of the connecting piece, so that they securely against the stop issue.
- the known fuse by means of safety spring can be very difficult to disassemble. It is the object of the invention to provide a connection arrangement for connecting a pressure line of a hydraulic system to another component of this system as well as a corresponding system in which the securing spring is easy to assemble and disassemble.
- connection arrangement for connecting a pressure line of a hydraulic system to another component of this system
- the securing spring, the connection socket and the connecting piece are designed for better demonstrability by hand such that the securing spring in the mounted state relative to the connection socket and the connection piece has a clearance fit.
- the arrangement has a fixing element for fixing the securing spring in its assembled state, wherein the fixing element is then in turn bushing-mounted mountable.
- a socket-fixed mounting is to be understood as meaning a direct mounting on the connection socket or a mounting on a component permanently connected to the connection socket.
- the fixing element engages over the base of the securing spring and thus fixes it.
- the arrangement further comprises a sealing element for sealing the inserted into the connection socket connecting piece.
- sealing elements are known in principle from the prior art for this application.
- the sealing element is designed in particular as an O-ring.
- the connecting piece is formed by a line end of the pressure line or at least has such a line end of the pressure line.
- connection piece only has the line end piece, then the connection piece advantageously continues to have a connector element plugged onto the line end piece.
- the connector element preferably forms the stop of the inserted connection piece.
- connection socket is formed in the further component of the hydraulic system.
- This further component may inter alia be a connecting element for connecting the one pressure line to another pressure line of the hydraulic system.
- the fixing element is an attachment of the further component of the system.
- This attachment can be an existing attachment of this component anyway.
- the fixing element by means of a screw bushing is fixed mountable. If the fixing element is an attachment of the further component of the system, then this attachment is screwed, for example, to a base body of the component, which simultaneously forms the connection socket.
- the hydraulic system is a hydraulic system of a motor vehicle and the further component is a motor vehicle component.
- the further component is in particular a component of an actuating device for a clutch of the motor vehicle.
- the hydraulic system according to the invention has at least one pressure line, at least one further component and at least one connection arrangement for connecting the at least one pressure line to the at least one further component, wherein the connection arrangement or at least one of the connection arrangements is designed as an aforementioned connection arrangement.
- the hydraulic system is in particular a hydraulic system of a motor vehicle.
- FIG. 1 shows a pressure line of a hydraulic system of a motor vehicle, which is connected to a further component by means of a connection arrangement
- FIG. 2 shows a securing spring of the connection arrangement shown in FIG. 1, FIG.
- Fig. 3 the pressure line and the further component of Fig. 1 in a sectional view
- FIG. 4 shows the connection arrangement shown in FIG. 1 in a further illustration.
- connection arrangement 10 for connecting a pressure line 12 of a hydraulic system of a motor vehicle to a further component 14 of this system.
- this further component 14 is a component of an actuating device for a clutch of the corresponding motor vehicle.
- the component 14 forms connection sockets 16 for connection to the pressure lines 12 of the system, wherein in FIG. 1 only one of these sockets 16 can be seen.
- a connection socket 22 formed by a line end piece 18 of the pressure line 12 and a connector element 20 is inserted.
- the line end 18 of the pressure line 12 and the connector element 20 are not visible in Fig. 1, but are shown as well as the resulting connection piece 22 in the sectional view of FIG.
- a securing spring 26 perpendicular to the insertion direction (arrow 28) of the connecting piece 22.
- This securing spring 26 shown in detail in FIG. 2 is a securing spring 26 for securing the connection against unintentional loosening of the connection piece 22 from the connection socket 16. It is U-shaped, ie has a base 30 and two legs 32, 34. The securing spring 26 is designed as a wire form spring.
- FIG. 3 shows a sectional drawing of the connection of the pressure line 12 formed by means of the connection arrangement 10 to the component 14.
- the cut is made, in particular, by the connection sockets 16 and the one formed in this component 14
- the connector element 20 surrounds a portion of the inserted line end piece 18 sleeve-like, which has a bead 36. By this bead 36, the connector element 20 is fixed on the line end 18 in the insertion direction.
- a sealing element 40 for sealing the connecting piece 22 pushed into the connecting socket 16 is arranged in front of the one head end 38 of the connector element 20.
- This sealing element 40 is formed as an O-ring.
- the legs 32, 34 of the securing spring 26 engage behind the opposite other head end 42 of the connector element 20. This other head end 42 forms a stop 44 of the inserted connecting piece 22nd
- the legs 32, 34 of the U-shaped locking spring 26 engage in the mounted state in the recesses 24 in the socket 16 and engage behind the stop 44 of the inserted connecting piece 22, wherein the securing spring 26 in this mounted state relative to the connection socket 16 and the Connecting piece 22 has a clearance.
- the securing spring 26 can be grasped for disassembly on the base 30 and then pulled out without much effort.
- the mounting position of the securing spring 26 would be unsecured in such a clearance fit even against unwanted disassembly of the clip 26 without further action. Therefore, a fixing member 46 is provided for fixing the securing spring 26 in its assembled state, which in turn is mounted bushing fixed. Under a socket-fixed mounting is to be understood both a direct mounting to the connector 16 or a mounting on a permanently connected to the connector 16 component.
- FIG. 4 shows such a fixing element 46, which in the example shown is a plate-shaped attachment 48 of the further component 14.
- This attachment 48 is attached to a main body 50 of the further component 14 by means of a (not shown) screw.
- the fixing element 46 that is, the attachment 48, overlaps the base 30 of the clip 26 and fixes it in its mounting position.
- the connection arrangement 10 shown in the exemplary embodiment is characterized by the following points:
- the locking spring 26 has a certain U-shape, which allows a clearance fit.
- the safety spring 26 is always mounted by your interpretation by hand and disassembled.
- the securing spring 26 locks the line via the connector element 20.
- the securing spring 26 is secured by the existing attachment 48 of the other component 14 from accidental loosening.
