- motors of this type also include means for supporting a brush-holder plate, arranged in the stator near one of its ends, these support means being maintained in the mounting position in the stator by elastic means interposed between the corresponding flange and these means.
- some motors are also equipped with means for detecting the rotation of the shaft comprising a first portion carried by this shaft and a second portion carried by a corresponding flange.
- the object of the invention is to propose various improvements to motors of this type, with a view to simplifying their structure and assembly and reducing their manufacturing cost.
- the subject of the invention is an activation motor, for example of a functional member of a motor vehicle, of the type comprising a stator in which a rotor is arranged, the stator comprising at each of its ends, a flange of guiding the corresponding end of a shaft connected to the rotor, each guide flange comprising a guide bearing adapted to receive a corresponding end portion of the shaft when mounting this flange on the stator, and means for detection of the rotation of the shaft comprising a first portion carried by this shaft and a second portion carried by a corresponding flange, characterized in that the second portion of these detection means carried by the corresponding flange is arranged on a printed circuit board adapted to be engaged in a corresponding receiving imprint of the flange, and in that the flange and the plate have complementary locking means in the mounting position by elastic snap-fastening.
- the second portion of the detection means is bonded or welded to the corresponding flange.
- each flange has axial stop means adapted to cooperate with the corresponding end of the shaft in order to maintain the rotor in the axial position in the stator.
- this motor also comprises means for supporting a brush-holding plate, arranged in the stator near one of its ends, these support means being held in the mounting position in the stator by elastic means interposed between the corresponding flange and these means and in the motor according to the invention, the elastic means comprise at least one elastic tongue made integrally with the rest of the flange, this tongue being adapted to elastically stress the support means of the brush holder plate in the mounting position in the stator and allow a take-up of the mounting clearances of these in the stator.
- an elastic ring is disposed between the flange and the means for supporting the brush-holder plate to maintain these in the mounting position.
- - Fig.l shows a schematic sectional view illustrating the general structure of an activation motor according to the invention
- - Fig.2 shows a side view illustrating a flange forming part of such an engine
- - Fig.3 shows an end view of a flange forming part of such an engine
- - Fig.4 shows a top view of a second portion of rotation detection means, forming part of such a motor.
- an activation motor for a functional member of a motor vehicle is recognized, this motor being designated by the general reference 1.
- This motor is then a DC motor and permanent magnets.
- such an activation motor co-carries a stator designated by general reference 2, in which a rotor designated by general reference 3 is arranged.
- the stator has at each of its ends, a flange for guiding the corresponding end of a shaft connected to the rotor.
- flanges are designated by the general references 4 and 5 in this FIG. 1.
- the shaft is in turn designated by the general reference 6 and has ends 7 and 8 respectively, guided in the guide flanges 4 and 5.
- each guide flange 4 and 5 comprises a guide bearing respectively 9a and 9b, adapted to receive the corresponding end portion of the shaft during mounting of the flange on the stator.
- a guide bearing respectively 9a and 9b, adapted to receive the corresponding end portion of the shaft during mounting of the flange on the stator.
- these flanges and of these guide bearings have already been described in the prior art. It will be noted, for example, that these guide bearings can be in the form of rings received in corresponding cages of the flanges.
- bearings made integrally with the flanges can also be envisaged.
- Each flange 4,5 also includes axial stop means adapted to cooperate with the corresponding end of the shaft in order to maintain the rotor in the axial position in the stator.
- These axial stop means are designated by the general references 10 and 11 in this FIG. 1, respectively for the flanges 4 and 5.
- these axial abutment means can for example be constituted by an abutment surface integrally formed with the rest of each corresponding flange, this abutment surface being adapted to extend opposite at least part of 1 ' corresponding end of the shaft in order to lock the latter in the axial position.
- these abutment means could comprise an abutment surface integrally formed with the rest of the flange. It goes without saying of course that other embodiments of these abutment means can be envisaged.
- these stop means may comprise a stop member produced separately from the rest of the flange and fixed on the latter.
- This stop member can then for example be in the form of a washer fixed for example by fitting into the flange, this washer being adapted to maintain the corresponding end of one shaft and therefore the rotor in the axial position.
- a motor may also include means for supporting a brush-holding plate, arranged in the stator near one of its ends, these support means being maintained in the mounting position. in the stator by elastic means interposed between the corresponding flange and these means.
