Definitions
- the invention relates to a pressure sensor module for electronic brake systems in motor vehicles.
- FIG. 1 is a sectional drawing through a cylindrical element which is directed into a section of a sensor housing and into a section of a hydraulic housing, which are connected to the element exclusively by means of a housing deformation caused by self-caulking,
- FIG. 2 shows an alternative embodiment of the element shown in FIG. 1, with a fastening combination consisting of self-locking in the hydraulic housing and a press connection of the element in the sensor housing,
- Fig. 5 is an overall view of the sensor housing with several fastened therein by self-caulking Elements, of which only the elements arranged at the ends of the sensor housing are connected to the hydraulic housing by self-caulking,
- FIG. 6 shows a functional modification of the elements which are arranged at the ends of the sensor housing and which, in addition to a fastening function, fulfill a flow function.
- a pressure sensor module which is used in particular for electrohydraulic brake systems, is presented with reference to FIGS. 1 to 6.
- a pressure sensor module accommodates a plurality of pressure sensors arranged in a sensor housing 13, the flange surface of which is attached to the connection surface of a hydraulic housing 12 in such a way that a plurality of pressure channels 14 arranged in the sensor housing 13 and in the hydraulic housing 12 are connected to one another for the purpose of pressure detection.
- the invention provides that a cylindrical element 3 provided with two fastening sections 1, 2 is arranged between the flange surface 4 and the connection surface 5, which extends from there with its diametrical fastening sections 1, 2 into the sensor and hydraulic housing 13, 12.
- a first receiving bore 6 opens into the flange surface 4 of the sensor housing 13, in which the first fastening section 1 of the cylindrical element 3 extends in a non-positive and / or positive manner.
- a second receiving bore 7 opens into the connection surface 5 of the hydraulic housing 12, in which the second fastening supply section 2 of the cylindrical element 3 is arranged non-positively and / or positively.
- a collar 8 with two annular surfaces is arranged, the annular surface facing the sensor housing 13 abutting an edge of the first receiving bore 6 and the second annular surface facing the hydraulic housing 12 abutting an edge of the second receiving bore 7 ,
- Both receiving bores 6, 7 are aligned coaxially to one another, one of the two receiving bores 6, 7 having a recess 9 into which the collar 8 is completely immersed.
- the circular recess 9 is in each case made in the flange surface of the sensor housing 12.
- the structurally cylindrical element 3 is provided on at least one of the two fastening sections 1, 2 on its circumference with at least one constriction 10 of high material hardness, into which, depending on the immersion depth of the element 3, at least one of the two receiving bores 6, 7 either the material of the sensor housing 13 which is softer than the constriction 10 or the material of the hydraulic housing 12 which is softer than the constriction 10 is displaced for sealing and fastening purposes.
- at least the fastening section 1, 2 of the element 3 provided with the constriction 10 is made of steel, preferably of free-cutting steel, or brass.
- the sensor housing 13 and / or the hydraulic housing 12 consists of a light metal, preferably of a wrought aluminum alloy. An extruded profile is particularly suitable for this.
- the cylindrical element 3 is advantageously used as a pressure pipe for passing the hydraulic housing 12 existing pressure in the direction of the sensor housing 13, so that the element 3 not only fulfills a fastening but also a flow function.
- the invention provides that the cylindrical element 3 carries a measuring element 11 for detecting the pressure in the hydraulic housing 12, for which purpose the cylindrical element 3 is designed as a measuring tube to which the measuring element 11 is attached to the tube end arranged in the sensor housing 13.
- the fastening of the element 3 in the hydraulic and sensor housing 12, 13 consisting exclusively of self-caulking on the two fastening sections 1, 2, for which purpose the first fastening section 1 is first pressed into the stepped receiving bore 6, so that the material of the sensor housing 13, which is softer than the element 3, is displaced or compressed into the constriction 10 by a shoulder 15 adjoining the constriction 10.
- the element 3 thus takes over the function of a caulking punch, the feed movement of which is generated by an axial force acting on the collar 8.
- the sensor housing 13 is aligned with the pressure channels 14 in the hydraulic housing 12 and pressed into the pressure channels 14 with the second fastening sections 2 with a defined force in order to produce self-clinching.
- the first tubular fastening section 1 is provided with a press fit, so that the arrangement of a constriction 10 in the region of the first fastening section 1 can be dispensed with.
- the first fastening section 1 is therefore only made with a slight oversize to the first mounting hole 6.
- the selected press connection has the advantage that the sensor housing 13 can also be made of steel if desired or required.
- the second fastening section 2 is connected by self-caulking as already described for FIG. 1.
- a thread 16 is used to connect the first fastening section 1 to the sensor housing 13.
- the element 3 is sealed in the sensor housing 13 by means of a sealing cone 17 on the first fastening section 1, which, after the element 3 has been screwed into the first receiving bore 6, bears against a cone sealing seat above the thread 16.
- the second fastening section 2 is permanently connected to the hydraulic housing 12 by means of self-locking, so that the thread 16 cannot loosen either.
- FIG. 4 shows, starting from a fastening of the element 3 in the hydraulic and sensor housing 12, 13 according to FIG. 1, a cap-shaped upper part 18 for receiving a measuring element 11 welded onto the first fastening section 1.
- FIG. 5 shows a sectional side view of a block-shaped sensor housing 13 with a plurality of tubular bodies fastened in parallel next to one another by means of self-caulking.
- the tubular bodies arranged at the two ends of the sensor housing 13 as the elements 3 mentioned at the outset are connected to the hydraulic housing 12 by means of self-caulking, which according to the embodiment according to FIG. 4 can also accommodate measuring elements 11 on their upper parts.
- the tubular bodies arranged in the further receiving bores 6 of the sensor housing 13 are only designed as caulked measuring element carriers 19, which have no mechanical connection to the hydraulic housing 12.
- These measuring element carriers 19 are connected to the pressure channels -14 of the hydraulic housing 12 via pressure measuring holes 20 in the flange surface 4.
- the flange surface 4 is sealed off from the connection surface 5 in the area of the pressure measuring bores 20 either by means of individual seals 21 or a sealing plate 22.
- the two external elements 3 are only used as fastening elements which are caulked into the sensor and hydraulic housing 12, 13 and which are connected via transverse channels 23 to two tubular bodies which are caulked into the sensor housing 13 and which form the tube body 5 correspond to known measuring element carriers 19. Between these two measuring element carriers 19 there are further measuring element carriers 19 which correspond in terms of their structure and their function to the explanations for FIG. 5.
- the sensor housing 13 has a wide contact surface, which is used to absorb the press-in force required to caulk the two outer elements 3 with the hydraulic housing 12.
- the wide contact surface 24 is laterally delimited by a housing frame 25 in which the measuring element carrier 19 and possibly also components or the entire required the pressure sensor electronics is located.
- the housing frame 25 is closed by a housing cover, not shown.
- the proposed invention creates a pressure sensor module that is particularly easy to attach to a hydraulic housing, the elements 3 proposed for attachment being designed in such a way that the elements 3 perform additional functions such as, for example, pressure propagation into the sensor housing 13 and the accommodation of the measuring elements required for pressure detection 11 or a sealing function.
