Description

TECHNICAL FIELD

[0001] The invention relates to a housing having a receiving area for a bracket of a mounting unit, the bracket being fixed to the receiving area by means of a material-bonded connection, wherein the receiving area is provided with a recess having a centering section for the bracket and having a positioning section for the bracket acting in the axial direction, the positioning section transitioning via a housing edge into an adjacent housing wall. BACKGROUND

[0002] In Figure 1 A region of such a housing is shown exemplarily with respect to the prior art. The housing 100 has a receiving area 101 having a centering section 102 for a bracket 110 of a mounting unit 111 and a positioning section 103 for the bracket 110. The centering section 102 extends at least substantially axially, while the positioning section 103 extends at least substantially radially and is located directly adjacent to the centering section 102. A material-bonded connection 108 acting between the bracket 110 and the housing 100 is provided in the radially extending region of the centering section 102. The positioning section 103 transitions via a housing edge 106 into an adjacent housing wall 107. The housing edge 106 leads to a clear defect after establishing the material-bonded connection 108, since the housing edge triggers an axial force directed onto the bracket 110, which continues in front of the housing 100, by which the material-bonded connection 108 is loaded. SUMMARY

[0003] It is an object of the invention to configure a receiving area on a housing for a bracket of a mounting unit, such that the bracket is received on the housing without axial forces after establishing a material-bonded connection.

[0004] To achieve this object a housing is provided, which has a receiving area for a bracket of a mounting unit, the bracket being fixed to the receiving area by means of a material-bonded connection, wherein the receiving area has a centering section for the bracket and, if necessary, a positioning section for the bracket acting in the axial direction, the positioning section transitioning via a housing edge into an adjacent housing wall.

[0005] It is particularly meaningful that the receiving area is provided with a channel acting in the axial direction with respect to the bracket at least in the radially extending region of the housing edge.

[0006] The channel, by virtue of its at least radial extension in the region of the housing edge, provides a spacing between the housing edge and the carrier of the mounting unit and thus prevents the housing edge from being reacted onto the carrier by means of an axial force acting in the direction of the mounting unit. This relieves the load on the material- bonded connection of the carrier of the mounting unit to the housing and reduces the risk of damage at the material-bonded connection. The housing can be, for example, a housing of a coupling device, for example a hydrodynamic torque converter, a hydraulic clutch or a wet-running clutch, which is typically used, for example, in motor vehicles. The carrier can be, for example, part of a clutch device which is used to connect a respective drive to a driven mechanism, for example a multi-stage transmission, and which can be used in motor vehicles in addition to an internal combustion engine as a first drive, for example, in addition to an electric motor as a second drive.

[0007] With regard to the centering section of the receiving region, the centering section has an at least substantially axial extension direction for centering the carrier, while the positioning section of the receiving region has an at least substantially radial extension direction for axially supporting the carrier. Particularly preferably, the channel is provided in the first embodiment on the positioning section to extend on the housing edge at least substantially parallel to the abutment face of the carrier up to the axial abutment face of the positioning section which extends radially inwards.

[0008] Here, if the positioning section is directly adjacent to the centering section, the channel is then preferably opened into the axial abutment face of the positioning section by means of a rounding.

[0009] If a material-bonded connection is provided in the region of the extension of the centering section, the channel is then separated from the material-bonded connection by the axial abutment face of the positioning section.

[0010] By this arrangement of the channel, the channel is provided in a radially extending region of the housing edge and thus establishes the desired axial spacing between the housing edge and the corresponding abutment face of the carrier of the mounting unit. At the same time, the carrier of the mounting unit is well supported axially on the abutment face by the axial abutment face which is provided radially between the channel and the centering section.

[0011] In the second embodiment, the housing is provided on the receiving region with a centering section which has an at least substantially axial extension direction for centering the carrier. The channel approaches the abutment face of the carrier on the housing edge at an angle a, so that with its radially inner end it forms an axial abutment face for the carrier of the mounting unit. This embodiment thus has the advantage that no separate positioning section with an axial abutment face is required on the receiving region, since this task is taken over by the channel.

[0012] If the channel here leads radially inwards up to the centring section and the material-bonding connection is provided in the region of the extension of the centring section, the channel here helps to form the material-bonding connection together with the carrier. Here with reference to the abutment face 16 of the carrier 4, the angle a of the channel should be below 90° and particularly preferably at least substantially 75°.

[0013] In this embodiment, the channel has its greatest axial extension in the edge region in which the housing edge lies, and the axial extension decreases with increasing radial distance from the housing edge. At the latest when the centring section is reached, the axial extension decreases to zero. Thereby, when the radial extension of the channel leads up to the centring section and the material-bonding connection is likewise in the region of the centring section, the material-bonding connection is always formed outside the material, i.e. outside the channel. BRIEF DESCRIPTION OF DRAWINGS

[0014] The housing is described in detail below with reference to the drawings. Therein are shown:

[0019] In Figure 2A region of the housing 1 is shown in which the housing has a receiving region 3 in the housing wall 2 for a holder 4 of the mounting unit 5. The receiving region 3 has a centring section 6 and a positioning section 7, wherein the centring section 6 serves for centring of the holder 4 and extends at least substantially axially, while the positioning section 7 is provided with an axial abutment face 8 for axial positioning of the holder 4 and extends at least substantially radially. The positioning section 7 here adjoins the end 9 of the centring section 6 facing the housing wall 2 radially and has the axial abutment face 8 for the holder 4 on a radially inner region thereof adjacent to the centring section 6. At least substantially radially within the axial abutment face 8, a connection 10 in the form of a weld seam is provided between the holder 4 and the housing 1 and in the region of the extension of the centring section 6. Radially outside the axial abutment face 8, in particular on a radially outer end 11 thereof, a channel 12 is provided, which forms an axial gap 13 between an axial abutment face 16 of the holder 4 and a housing edge 14 of the housing wall 2. On the basis of this axial gap 13 and the channel 12, the housing edge 14 cannot reactively exert itself onto the axial abutment face 16 of the holder 4 and no axial forces continue from the housing which, by loading the material- bonded connection 10, would cause damage thereto.

[0020] The channel 12 can be configured in accordance with Figure 2 such that it begins on the housing edge 14 and extends radially inwards at least substantially parallel to the abutment face 16 of the holder 4 in order to open out into the axial abutment face 8 of the positioning section 7 by means of a rounding 15. However, instead of this, the channel 12 according to Figure 3 also begins on the housing edge 14, approaches the abutment face 16 of the holder 4 at an angle a, wherein the angle a, with reference to the abutment face 16 of the holder 4, should be less than 90° and, for example, have a value of 75° as shown in Figure 3 . In this embodiment, the channel 12 is guided radially inwards such that a radially inner end 17 of the channel serves as an axial abutment face 8' of the holder 4 and at the same time also assists in forming the material-bonded connection 10, which is configured to point in the direction of the abutment face 8' from a free side 18 of the housing wall 2.

[0021] According to the explanations to date, the channel 12 is always provided on the receiving region of the housing 1. However, it is naturally also possible to provide a channel on the holder 4 of the mounting unit 5, for example in the abutment face 16 of the holder 4.

[0022] The figures referred to up to this point have always only shown a partial region of the housing 1 and the holder 4 of the mounting unit 5, in Figure 4 a larger region is shown. As can be seen, the housing 1 can be, for example, a part of a coupling device 19 at least partially filled with a fluid, for example a hydrodynamic torque converter, a hydraulic clutch or a wet-running clutch, which is used, for example, in motor vehicles. According to Figure 4The housing 1 has a shaping section 20, which can be used to accommodate stacked clutch elements. The bracket 4, housed in the receiving area 3 of the housing 1, can be part of the clutch device 21. For example, in a motor vehicle where an internal combustion engine serves as the first drive and an electric motor serves as the second drive, the clutch device can be used as a supplement to the coupling device 19, wherein the clutch device 21 is used to connect the corresponding drive and driven mechanism, such as a multi-stage gearbox. Figure 4 In the illustrated embodiment, the carrier 22, housed by the support 4, is used to position the motor.
