Description
Unit with a machine fastened to it 2295436
Prior art
The invention relates to a unit, for example an ABS (anti-lock brake system) or ASR (traction- control) unit, with a housing. This can be, for example, a hydraulic block of a unit of this kind to which a machine, for example a pump drive =tor, is fastened.
It has hitherto been customary to screw pump drive motors of units of this kind to the housing by means of screws or bolts and nuts. This method of fastening has the disadvantage that separate fastening is components are required and that threads must be provided in the housing or in the machine. Screwing the machine to the housing further=re takes up time during assembly.
Advantages of the invention The unit according to the invention with the features of Claim 1 has the advantage that the fastening of the machine to the housing Is economical due to the elimination of separate fastening components and that fastening can be carried out quickly and in well suited to automation. The fastening in the case of the unit according to the invention furthermore forms a reliable connection between the machine and the housing and a safeguard against spontaneous detachment is superfluous. Detachment of the motor from the housing and subsequent refastening by unauthorized persons and hence inappropri- ate interference in virtually excluded, something which may well be required in the case of ABS or ASR units to guarantee their operation, I. e. for safety reasons.
The subclaims relate to advantageous further developments and improvements of the invention.
Drawing The invention is explained in greater detail below with reference to two exemplary embodiments, which are illustrated in the drawing. The two figures show two sections through embodiments of units according to the invention in the region of a joint.
Description of the exemplary embodiments
Figure 1 shows a section through part of'a unit according to the invention, denoted overall by 10. As a machine, a pump drive motor 12 in mounted externally on one wall of a housing 14 of the unit 10.
The motor 12 has a motor shaf t 16 with a rotor winding 18 mounted on it. The motor shaft 16 is rotatably supported by means of two ball bearings 20, of which only one can be Been in the drawing. One of the two ball bearings 20 in inserted into a housing cover 22 of the pump drive motor 12, the cover, for its part, closing a motor housing 24 at an and facing the housing 14 of the unit 10.
At its end facing the unit housing 14, the hollow-cylindrical motor housing 24 projects beyond the motor housing cover 22 in the axial direction. The projecting part of the motor housing 24 forms an all round fastening portion 26. An end region 28 of the fastening portion 26 in bent over to form an all-round flange which projects radially outwards.
The pump drive motor 12 is placed by means of its motor housing cover 22 against the outside of the unit housing wall 14, its fastening portion 26 projecting into a circular slot 30 made in the unit housing wall 14. An all-round retention lip 32 which projects radially inwards and overlaps that end region 28 of the fastening portion 26 of the motor housing (24) which is bent over to form a flange in formed by rolling in. In this way, the puzmp drive motor 12 is connected to the unit housing 14. The connection is effective over the entire circum ference of the motor housing 24, as a result of which holding forces are uniformly distributed and no stresses arise at individual fastening points. By virtue of its formation over a large area and in a manner distributed around the entire circumference, this type of connection can furthermore transmit large holding forces between the unit housing 14 and the motor 12.
The motor housing 24 is sealed off with respect to the unit housing 14 by means of a sealing ring 34 inserted into the slot 30.
Figure 2 shows a second embodiment of a unit 10 according to the invention, in which the connection of a pump drive motor 12 to a unit wall 14 has been modified in comparison with the embodiment shown in Figure 1. otherwise, the unit 10 illustrated in Figure 2 is of identical construction to the unit illustrated in Figure is 1. To avoid repetition, only the changes with respect to the embodiment illustrated in Figure I are explained below with reference to Figure 2. Corresponding reference numerals are used for the same components. The statements made with reference to Figure 1 may be ref erred to in addition.
In the case of the embodiment illustrated in Figure 2 of a unit 10 according to the invention too, the hollow-cylindrical motor housing 24 projects at its end facing the unit housing 14 beyond the motor housing cover 22, which is mounted on this end of the motor housing 24. This projecting part of the motor housing 24 forms a hollow-cylindrical fastening portion 36 which is formed all the way round and projects with little play into an annular slot 38 made in the unit housing 14. The fasten- ing portion 36 is provided at its outer circumference with recesses 40 formed by pressing in, a plurality of these recesses being arranged adjacent to one another in the axial direction of the motor housing 24 at several points distributed around the circumference. Material of the unit housing 14 is deformed into these recesses 40. This gives a positive and frictional connection between the motor 12 and the unit housing 14.
In the case of the embodiment of the invention illustrated in Figure 2, the deformation of the material of the unit housing 14 into the recesses 40 of the motor housing 24 is accomplished by caulking the unit housing 14 in the direction of arrow F f rom the outside of the said housing. Caulking can be performed around the entire circumference or at individual points distributed around the circumference, caulking in all cases being performed at points on the circumference at which the recesses 40 on the fastening portion 36 of the motor housing 24 are situated. Caulking produces a notch 42 in the unit housing 14.
Before the pump drive motor 12 is placed against the unit housing 14, i.e. before the fastening portion 36 of the pump drive motor 12 enters the annular slot 38 in the unit housing 14, a bealing compound 44 is injected is into the annular slot 38, sealing off the motor housing 24 with respect to the unit housing 14 after mounting of the motor 12.
If the force required to hold the motor 12 is relatively small, it is sufficient not to forsix the fastening portion 26, 36 of both embodiments of the invention all the way round but discretely in the f orm of tongues arranged in distributed fashion around the circumference which project in the axial direction from that end of the motor 12 which faces the unit housing 14, project into recesses in the unit housing 14 and are held there frictionally and/or positively by caulking, for example.
