Definitions
- the invention is based on a pressure-tight structural unit, in particular a hydraulic unit according to the preamble of claim 1.
- Such a hydraulic unit is known for example from DE 195 21 510 AI, in which a housing is made of a thermoplastic material and a recess is formed in the housing, in which an electromagnetic actuator is inserted.
- the actuator also has a plastic housing part that is pressure-tightly connected to the housing by welding or gluing.
- Claim 1 has the advantage that the pressure-tight connection can be produced by ultrasonic welding, the sonotrode required for welding not having to vibrate the mass of the functional unit, for example the magnet of an electromagnetic actuator, but only the much lower mass of the insert. In addition, the requirements for dimensional accuracy of the housing are lower.
- the functional unit can be preassembled in the housing, brought to radial and axial positions and checked for functionality before welding.
- a further expedient configuration of the gap and of the insert by means of which an externally visible throwing up of the material flowing during ultrasonic welding is avoided, is possible in that the insert has a wider outer ring and a narrower ring seated at the base of the gap, the narrower one Ring the two cutting edges are designed for the ultrasonic welding connection.
- FIG. 1 shows a pressure-tight unit in longitudinal section with a first embodiment of a Pressure-tight connection
- Figure 2 is an enlarged view of the pressure-tight connection according to the embodiment shown in Figure 1
- Figure 3 is an enlarged view of the pressure-tight connection according to a second embodiment
- Figure 4 is an enlarged view of the pressure-tight connection according to a third embodiment.
- FIG. 1 shows a hydraulic unit 10 with a housing 11 made of thermoplastic material and an electromagnetic actuator 12 inserted pressure-tight in the housing.
- a recess 13 is made in the housing 11, in which the electromagnetic actuator 12 is inserted.
- DE-OS 195 21 510 for a description of the mode of operation of the hydraulic unit 10, reference is made to DE-OS 195 21 510.
- the electromagnetic actuator 12 has a cover-shaped cover plate 15, which is also made of a thermoplastic
- a coil core 20 is inserted in the cylindrical interior of the coil body 17, which is open towards the sides.
- the cover plate 15 is formed from the potting material of the bobbin 17.
- the coil core 20 is designed with a central longitudinal bore 21 which is connected to a tank, not shown, for a pressure medium.
- a tank-side sealing seat 22 is formed at the end of the longitudinal bore 21 located within the coil former 17.
- the sealing seat 22 interacts with a closing element 23 of a movable armature 24.
- the hat-shaped anchor 24 also penetrates its cylindrical part through the coil body 17.
- a ball 26 pressed into the bottom of the hat-shaped armature forms the closing element 23.
- the armature 24 has a flange 27, which is penetrated by a plurality of passages 28.
- One end of an anchor spring 30 designed as a compression spring rests on the flange 27 and is supported at the other end on the fixed coil core 20.
- the armature spring 30 presses the armature 24 against an inlet-side sealing seat 31, which is sealed by the closing element 23, in the currentless state of the magnet coil 18.
- the inlet-side sealing seat 31 is arranged on a tubular inlet extension 32 formed on the housing 10 and lies with the sealing seat 22 formed on the coil core 20 in a common longitudinal axis.
- a further channel 34 is also formed in the housing 11, which leads to a hydraulic consumer (not shown).
- a circumferential, annular gap 40 with a base 41 on the housing side and a base 42 on the cover plate side is formed between the cover plate 15 and the housing 11.
- an annular insert 44 which rests with its inner end face both on the housing-side base 41 and on the cover plate-side base 42.
- FIGS. 2, 3 and 4 show an enlarged illustration of various exemplary embodiments of the arrangement for producing the pressure-tight connection. In the first exemplary embodiment illustrated in FIG.
- the base 41 on the housing side and the base 42 on the cover plate side are designed to run obliquely, so that the base 41 form a cutting-shaped, housing-side support 45 and on the base surface 42 a cutting-shaped, cover plate-side support 46.
- the annular insert 44 has an upper, wide ring section 47 and a lower, narrow ring section 48 set back on both sides.
- An outer ring surface 51 and an inner ring surface 52 form between the ring sections.
- the annular insert 44 now lies with the annular surfaces 51, 52 on the respective cutting edge
- FIG. 3 A second exemplary embodiment is shown in FIG. 3.
- the insert 44 also consists of a wide ring section 47 and a narrow ring section 48.
- the outer ring surface 51 and the inner ring surface 52 run between the two ring sections 47, 48.
- a V-shaped notch 54 is made in the end face of the narrow ring section 48 , so that two cutting-shaped ring surfaces 55 form on the end face of the annular insert 44.
- One of the blade-shaped ring surfaces 55 lie on the cover plate-side base 42 and the other of the blade-shaped ring surface on the housing-side base 41 of the narrow area of the gap 40.
- a free space 58 is formed between the annular surfaces 51, 52 and the adjacent base surface in the gap 40.
- FIG. 4 A simplified embodiment of the exemplary embodiment according to FIG. 3 is shown in FIG. 4.
- the ring-shaped insert is designed as a compact ring 60.
- the ring 60 also has a V-shaped notch 54, which forms two cutting-shaped ring faces 61 on the inner circumference and on the outer circumference, one of which rests on the housing-side base surface 41 and the other on the cover plate-side base surface 42.
- the welded connection during ultrasonic welding also arises in the area of the cutting-shaped ring surfaces 55 between housing 11, cover plate 15 and insert 44.
- the use of the ultrasonic welding method is not restricted to the described designs of the gap 40 and the insert 44.
