DETAILED DESCRIPTION

(8) In the FIGS. 1A through 2C, an embodiment example of a motor transmission connection arrangement 10 according to the present disclosure is represented. The motor transmission connection arrangement 10 comprises a motor pot 12 for the accommodation of an electric motor that is not represented, a brush holder 14, with which brushes, which are not represented, for the electric motor are held, and a transmission housing 16 for the accommodation of a likewise not represented drive.

(9) The motor pot 12 comprises first contact surfaces 18, by means of which the motor pot 12 comes into contact with the brush holder 14, when the brush holder 14 is plugged into the motor pot 12. Furthermore, the motor pot 12 exhibits second contact surfaces 20, by means of which the motor pot 12 comes into contact with the transmission housing 16, when the transmission housing 16 is plugged into the motor pot 12.

(10) In addition, the brush holder 14 exhibits third contact surfaces 24, by means of which the brush holder 14 comes in contact with the transmission housing 16, when the brush holder 14 and the transmission housing 16 are plugged into the motor pot 12. Pinching ridges 32, about which further details will be given later, are arranged on the third contact surfaces 24.

(11) Beyond this, the motor pot 12 comprises centering surfaces 50, which have an effect in the x-direction, and centering surfaces 52, which have an effect in the y-direction. The motor pot 12 comes into contact with each of the centering surfaces 50, 52, in its own right, both with the brush holder 14 as well as with the transmission housing 16, when the brush holder 14 and the transmission housing 16 are plugged into the motor pot 12. In other words, both the brush holder 14 as well as the transmission housing 16 abut respectively on one of the foreseen centering surfaces 50, 52.

(12) The brush holder 14 and the transmission housing 16 exhibit first mating surfaces 26, second mating surfaces 28 and third mating surfaces 30, by means of which they come in contact with the first, second or third contact surface(s) 18, 20, 24, when the brush holder 14 and the transmission housing 16 are plugged into the motor pot 12.

(13) In addition, the brush holder 14 and the transmission housing 16 exhibit centering mating surfaces 54, which in reference to the coordinate system indicated in the Figures, have an effect in the x-direction, and centering mating surfaces 56, that have an effect in the y-direction. As a consequence, the centering mating surfaces 54 extend parallel to a longitudinal axis L and lie in the y-z plane and upon contact with the centering surfaces 50 bring about a centering in the x-direction. Correspondingly, the centering surfaces 56 extend parallel to the longitudinal axis L and lie in the x-z plane. Upon contact with the centering surfaces 52 they bring about a centering in the y-direction with reference to the coordinate system.

(14) In the embodiment example represented, the centering mating surfaces 54 are designed in the x-direction as elevations 58 or are arranged on elevations 58. The centering mating surfaces 54 come into contact with the centering surfaces 50 and the centering mating surfaces 56 come into contact with the centering surfaces 52, when the brush holder 14 and the transmission housing 16 are plugged into the motor pot 12.

(15) Upon observation of the FIGS. 1A and 1B, one can recognize that the first, second and third contact surfaces 18, 20, 24 lie in a plane that is perpendicular to the longitudinal axis L of the motor transmission connection arrangement 10. In reference to the coordinate system, they extend in an x-y plane, whereby the longitudinal axis L extends parallel to the z-axis of the coordinate system.

(16) The first, second and third mating surfaces 26, 28, 30 also lie in the x-y plane that extends parallel to the longitudinal axis L. As a consequence, the first, second and third contact surfaces 18, 20, 24 have an effect as stops, which limit the movement of the motor pot 12, of the brush holders 14 and of the transmission housing 16 in relation to one another along the longitudinal axis L or alternatively the z-direction.

(17) Beyond this, the motor pot 12 exhibits a total of six crimping sections 36, with which the transmission housing 16 can be fastened to the motor pot 12 and whereby the brush holder 14 is braced between the motor pot 12 and the transmission housing 16.

(18) To fit the motor transmission connection arrangement 10, the brush holder 14 is initially inserted into the motor pot 12, until the first mating surfaces 26 of the brush holders 14 come into contact with the first contact surfaces 18 of the motor pot 12. In so doing, the centering mating surfaces 54 in the x-direction and the centering mating surfaces 56 in the y-direction of the brush holders 14 come in contact with the centering surfaces 50 in the x-direction and the centering surfaces 52 in the y-direction of the motor pot 12, whereby the brush holder 14 is oriented concentric to the motor pot 12 with regard to the longitudinal axis L.

(19) Subsequently, the transmission housing 16 is inserted in the motor pot 12, up until the second mating surfaces 28 come into contact with the second contact surfaces 20 of the motor pot 12 and the third mating surfaces 30 with the third contact surfaces 24 of the brush holders 14. In so doing, the centering mating surfaces 54, 56 in the x- and in the y-direction of the transmission housing 16 come into contact with the centering surfaces 50, 52 in the x- and in the y-direction of the motor pot 12, in such a manner that also the transmission housing 16 in reference to the longitudinal axis L is concentrically oriented to the motor pot 12. As a consequence, the centering surfaces 50, 52 in the x- and in the y-direction and the centering mating surfaces 54, 56 in the x- and in the y-direction have a centering effect including in reference to the transmission housing 16.

(20) In particular, it should be learned from FIG. 1A, that the motor pot 12 exhibits in total three first contact surfaces 18, which are arranged in a recess of the wall of the motor pot 12 that extends in the approximately rectangular cross section. Correspondingly, the brush holder 14 exhibits three first mating surfaces 26, which are arranged on projections of the brush holders 14, which can impinge in the recesses of the motor pot 12. The transmission housing 16 also exhibits three third mating surfaces 30, which can impinge in the recesses of the motor pot. The recesses are arranged in such a manner that the brush holder 14 and the transmission housing 16 can only be introduced in a turning position in the motor pot 12. In order to fasten the transmission housing 16 to the motor pot 12, the crimping sections 36 are bent radially inwards to the longitudinal axis L, in such a manner that a form-fit lock is created between the transmission housing 16 and the motor pot 12. The crimping sections 36 exhibit crimping surfaces 38 (see FIG. 1B) that lie approximately in the x-y plane and come in contact with the crimping mating surfaces 40 of the transmission housing 16 (see FIG. 1A). The crimping mating surfaces 40 extend approximately in the x-y plane; they are however somewhat tilted towards the x-y plane. Upon crimping or alternatively upon bending of the crimping sections 36, the crimping surfaces 38 cause friction against the crimping mating surfaces 40, in such a manner that a frictional lock is also at least partially provided.

(21) Since the brush holder 14 abuts on one side by means of its first mating surfaces 26 with the first contact surfaces 18 of the motor pot 12 and on the other side by means of its third contact surfaces 24 with the third mating surfaces 30 of the transmission housing 16, its position within the motor transmission connection arrangement 10 is unequivocally determined, as soon as the crimping sections 36 have been bent. On the basis of the tilting of the crimping sections 40 towards the x-y plane, a final positioning of the transmission housing 16 and the brush holders 14 in reference to the longitudinal axis L takes place. The pinching ridges 32 are designed in such a manner that they are swaged upon the bending of the crimping sections 40, whereby the play of the motor transmission connection arrangement 10 is compensated along the longitudinal direction.

(22) In FIG. 1C a general sectional representation through the motor transmission connection arrangement 10 is shown, when the motor pot 12, the brush holder 14 and the transmission housing 16 are plugged into one another. The FIG. 1C is intended to illustrate that, for example, in the sectional plane selected in FIG. 1C, the centering surface 50 of the motor pot 12 comes into contact both with the centering mating surface 54 of the brush holders 14 as well as with the centering mating surface 54 of the transmission housing 16. Further centering surfaces for centering in the x-direction are not foreseen. The centering in the x-direction takes place exclusively by means of the centering surface 50. The same holds true in a similar manner for the centering surface 52 in the y-direction. In so doing, it should be noted that for the case that is not illustrated, wherein the centering surface 50 exhibits a curvature around the longitudinal axis L and, for example, represents the interior surface of a hollow cylinder, the centering surface can also bring about a centering in this case in the y-direction.

(23) The FIGS. 2A through 2C show the motor transmission connection arrangement 10 in assembled state, whereby the crimping sections 36 have not yet been bent.
