Definitions
- the invention relates to a pole housing arrangement, in particular for wiper systems for motor vehicles according to the preamble of claim 1.
- a cylindrical edge portion of the pole housing is axially displaced over a cylindrical mounting flange of the gear housing with circumferential groove, whereupon the arrangement of Polgeophuse and gear housing in the circumferential direction is rotated past a punch tool which acts in the radial direction on the pole housing and this in the circumferential groove of Gear housing flange deformed, whereby a positive connection between the pole housing and gear housing is produced.
- a punch tool which acts in the radial direction on the pole housing and this in the circumferential groove of Gear housing flange deformed, whereby a positive connection between the pole housing and gear housing is produced.
- no additional fastening means such as fastening screws
- Another method of attachment which does not require any additional fastening means, is the caulking of tabs punched into an edge section of the pole housing around a respective bending edge of the gear housing.
- this method it is advantageous that no twisting movement of the pole housing and the gear housing must take place along a stamping tool.
- the disadvantage is that the production of deep-drawn pole housing is costly, since additionally / subsequently the tabs to be bent must be punched in the first continuous in the circumferential direction Polge Reifenand.
- the invention has for its object to provide a Polgetude-to-break in which the pole housing is fixed to the transmission housing without separate fastening means and in which the pole housing is of the simplest possible structure.
- the invention is based on the idea not to form the umbiegenden attachment portion as stamped into an edge portion of the pole housing tab, but to form the at least one mounting portion by bending a portion of a partially cylindrical before bending over edge portion.
- the at least one fastening section only arises during the fixing step by bending over a peripheral section of a hitherto partially cylindrical edge section.
- the at least one edge section extends continuously, ie without interruption, ie without being provided with pre-cuts, in the circumferential direction.
- the edge section before bending over the associated fastening section is a cylinder section with an end edge describing a partial circle.
- the pole housing as a simple deep-drawn part without holding features such as stamped tabs or mounting flanges, since the mounting portions are formed from the continuous material in the circumferential direction by bending in the actual attachment without a previous punching step.
- the fastening sections themselves are crimped or caulked to the transmission housing in order to produce a positive connection between the pole housing and the transmission housing. len.
- a rotation of the pole housing relative to the transmission housing and an axial movement between the housings in the fixed state is prevented.
- the known Rollierverbördelclar reduce the cost of the necessary processing machines or systems considerably, since no rotational movement must be realized in the attachment.
- only one bending punch is required, by means of which the pole edge edge is bent in sections around a bending edge of the transmission housing. Also, no separate fasteners, such as mounting screws needed.
- edge portions taken together form a continuous cylindrical Polge Reifenand.
- each attachment section continues at least before the Umbiege Kunststoff on both sides in the circumferential direction without interruption in the associated edge portion.
- the edges of the edge portions before bending together describe a full circle.
- this full circle is interrupted by one or more Zentrierstoffausappeleben, but have no holding function.
- the fastening portions are arranged distributed uniformly over the circumference of the pole housing.
- the provision of four evenly distributed over the circumference fastening portions has proved to be advantageous, wherein the associated edge portions describe a quarter-cylinder before bending.
- a fastening flange for fixing the pole housing is provided on the gear housing, on which at least one bending edge is provided for the at least one fastening section.
- the attachment flange preferably has a smaller diameter than the Polge Reifenand, so that the pole housing in the axial direction on the mounting flange can be folded, whereupon the attachment portions are formed by bending the cylindrical Polge Reifenandes.
- a groove is provided in an area radially within a bending edge forming the peripheral edge of the transmission housing flange in an embodiment.
- the bending edge forms a circumferentially extending, radially outer boundary of a Nutendwand delimiting the groove, up to which the groove extends in the axial direction.
- a radially outwardly open circumferential groove is introduced, in which, if necessary, an annular seal can be inserted or injected in order to seal the pole housing relative to the transmission housing and thus to avoid ingress of moisture.
- At least one centering device is provided on the pole housing, which is connected to a further centering device on the transmission housing.
- menwirkt is provided on the pole housing.
- the centering means of the pole housing is formed as a punched-out in an edge portion of the pole housing.
- the centering means has no attachment function, that is not bent around a bending edge, the scope of the invention is not thereby left.
- no pre-cuts are provided in the edge portion of the pole housing.
- FIG. 1 shows a perspective view of a pole housing before the fastening process
- FIG. 2 shows a perspective view of a pole housing shown in section, which is slipped over a mounting flange of a transmission housing, before the production of a positive connection
- FIG 3 shows a perspective view of a pole housing arrangement in which fastening sections of the pole housing are bent over in each case one bending edge of the fastening flange of the gear housing, and
- Fig. 4 is a plan view of the connection between the pole housing and the transmission housing.
- a formed as a deep-drawn part of metal pole housing 1 for receiving an electric drive motor for a windshield wiper system of a motor vehicle is shown.
- the pole housing 1 has a Polge Reifenand 2 offset inwardly in the radial direction.
- a punched-3 is introduced in the Polge Reifenand 2 .
- This punching 3 has no attachment function, but serves as a centering means, which cooperates with a centering means, not shown in Fig. 1 of a transmission housing, also not shown. Except for this exclusively serving as a centering punching the Polge Reifenand 2 extends as a continuous "band" in the circumferential direction, so it is not provided with pre-punching.
- the Polge Reifenand 2 can be mentally divided, for example, in four approximately equal edge portions 4a, 4b, 4c and 4d, which are integrally formed with each other and which are bounded by imaginary, dashed axial dividing lines 5.
- Each edge portion 4a, 4b, 4c, 4d extends continuously, ie without interruption in the circumferential direction.
- a partial section (circumferential section) of each edge section 4a, 4b, 4c, 4d is bent radially inwards and thus forms in each case a fastening section which is caulked or crimped with a gear housing.
- a free end edge 6a, 6b, 6c, 6d of each edge portion 4a, 4b, 4c, 4d essentially describes a quarter circle, that forms the end edge of each quarter cylinder. Together describe the end edges 6a, 6b, 6c, 6d of the edge portions 4a, 4b, 4c, 4d (except for the recess 3) a full circle.
- FIG. 2 an alternately illustrated pole housing 1 is shown, which is slipped axially with its Polge Reifenand 2 via a mounting flange 7.
- the Polge Reifenand 2 has in the embodiment shown a larger diameter than a subsequent cylinder in the axial direction section 8, but could also be formed directly from an end portion of the cylinder portion 8.
- the Polge Reifenand 2 extends continuously in the circumferential direction and can be divided into four imaginary edge portions, of which only one edge portion 4a is designated reference numerals.
- the edge portion 4a is formed by a quarter cylinder portion. Approximately in the middle, the edge portion 4a projects beyond a bending edge of the fastening flange 7, wherein the bending edge is covered by the pole housing 1 and therefore can not be seen.
- the covered bending edge corresponds to the adjacent, cut-free bending edge 9, which is formed by a peripheral edge of the mounting flange 7.
- All four circumferentially spaced bending edges 9 bound each one extending in the circumferential direction and in the radial direction Nutendwand 10, each defining a groove 11 extending in the axial direction in the axial direction.
- Each edge portion 4a, 4b, 4c, 4d is bent radially inwardly in its middle, the groove 11 partially overlapping portion. The inwardly bent part of cut the associated edge portion forms a mounting portion.
- a circumferential groove 12 is introduced, in which a ring seal 13 is placed. This lies radially inward on the pole housing 1, whereby moisture ingress into the pole housing 1 is avoided.
- the pole housing 1 is fixed to the mounting flange 7 of the transmission housing. It can be seen that the mounting flange 7 engages with a projection 14 in the punched-3, whereby an alignment between the pole housing 1 and gear housing is achieved.
- a respective attachment portion 15a, 15b, 15c, 15d is formed.
- Each attachment portion 15a, 15b, 15c, 15d is a peripheral portion of the associated edge portion 4a, 4b, 4c, 4d, each attachment portion 15a, 15b, 15c, 15d bent around the associated bending edge 9 of the mounting flange 7 radially inwardly and thus with the mounting flange 7 is crimped, whereby a withdrawal of the pole housing 1 in the axial direction is prevented by the mounting flange 7.
- the bending takes place in such a way that the respective edge section 4a, 4b, 4c, 4d does not tear during bending, that is, it continues continuously without interruption in the circumferential direction.
- the mounting portions 15a, 15b, 15c, 15d are shown in a plan view from the direction of the transmission housing.
- the attachment portions 15a, 15b, 15c, 15d abut respectively on a Nutendwand 10 of the associated groove 11 and thus form a positive connection with the mounting flange. 7
