TRANSMISSION-PROPULSION UNIT
Prior Art
The invention emanates from a transmission-propulsion unit according to the genre of the main claim.
A transmission-propulsion unit according to the genre of the main claim is established in DE 100 19 512 A1.
The transmission-propulsion unit that is established in this paper has a casing at which several fastening towers are provided. Apart from this, the established transmission-propulsion unit has propulsion that is designed as electro-motor propulsion and is especially meant for window-lift and sliding sunroof motors in an automobile. The casing, thereby, has a modular structure i.e. different transmission and electronic casings can be joined to different engine casings through an engine lining of the transmission-propulsion unit. Fastening of the transmission-propulsion unit's casing takes place, for example, by screwing the casing on to the fastening towers at a car body component or at a seat construction. This determines the spatial location of the transmission-propulsion unit. The disadvantage with the established transmission-propulsion unit is that a new construction of the transmission-propulsion unit's casing is required for a modified screw-on map in which the fastening locations have been changed. The transmission-propulsion unit, in particular, which is assembled in a modular manner, is generally suitably only for a specific application.
Advantages of the Invention
In contrast, the advantage exhibited by the transmission-propulsion unit, in accordance with the invention, with features of the main claim, is that a fastening

with regard to at least two different screw-on maps can take place without any modification to the transmission-propulsion unit's casing. The transmission-propulsion unit in accordance with the invention can thus be employed for the same purpose even if the conditions are changed e.g., as a window-lift motor in various automobiles in which the fastening has to take place differently. Apart from this, the transmission-propulsion unit can be employed for different purposes e.g., as a window-lift or sliding sunroof-transmission-propulsion unit even if diverse fastenings are required i.e. different screw-on maps exist for these two applications.
Advantageous development of the transmission-propulsion unit specified in the main claim is possible through the measures listed in the sub claims.
It is an advantage that the fastening tower is connected to the transmission-propulsion unit's casing by a dovetail link. This enables a continuous displacement of the fastening tower to take place within a certain framework relative to the transmission-propulsion unit's casing so that a plurality of fastening possibilities exists.
The fastening tower is advantageously connected to the transmission-propulsion unit's casing by means of a welding seam. This provides a constructive, simple fixing of the fastening tower at the casing, which exhibits high mechanical stability. As an alternative to the welding seam, fixing of the fastening tower to the casing can also take place through a screw fastening.
Of advantage is that at least one other fastening tower is provided and that the fastening tower and the other fastening tower together have one base plate so that they can be jointly connected to the casing. Manufacture of the transmission-propulsion unit can thereby be considerably simplified since the

fastening towers that are connected to one another can be positioned and fixed together vis-a-vis the casing.
Of particular advantage is that the casing has an annulus-shaped section, at least in sections, so that the common base plate of the fastening towers and of the other fastening tower partially encircles the annulus-shaped section and can be linked to the annulus-shaped section at the first and second juncture. Manufacture of the transmission-propulsion unit with regard to a pre-determined screw-on map is thereby further simplified since only a degree of freedom viz. turning the base plate relative to the casing, still exists in the case of a predetermined location of the fastening tower with regard to the base plate. With regard to various screw-on maps, customisation can then take place either by fixing the common base plate of the fastening tower to the casing by displacing same through turning or by manufacturing different base plates that provide a varying location of the fastening towers and/or a varying number of fastening towers for fixing at the casing subject to the screw-on map provided.

Description of the Exemplary Embodiments
Fig. 1 illustrates a first exemplary embodiment of a transmission-propulsion unit 1 of the invention. The transmission-propulsion unit 1 serves, in particular, to move movable parts in an automobile e.g., to move a window or a sliding sunroof. The transmission-propulsion unit 1 in accordance with the invention is, however, also suitable for other applications.
The transmission-propulsion unit 1 comprises of a casing 2 that is made up of a transmission case 3 and a propulsion case 4. The transmission case 3 of the casing 2 has an annular-shaped section 5 that is interrupted in the region of the propulsion case 4 of the casing 2. Fastening towers 6, 7, 8 are affixed at the transmission case 3 and a fastening tower 9 is affixed to the propulsion case 4 by a fixing element 10, whereby the fixing element 10 is a part of the casing 2.
The fastening towers 6, 7 8 can be moved along the circumference 15 of the annulus-shaped section 5 before being fixed at the annular-shaped section 5 of the transmission case 3. Due to the ability to reposition, the position of the fastening towers 6, 7 8 can be customised to a pre-determined screw-on map. The fastening tower 9 can be moved along the flange 16 of the fixing element 10 of the casing 2 when it is in an un-fixed condition. Apart from this, the fastening tower 9 can also be fixed to the flange 17. Customisation to the pre-determined

screw-on map can take place depending on the position selected for the fastening tower 9 i.e. at the flange 16 or at the flange 17.
Affixing the fastening tower 7 to the annular-shaped section 5 of the casing 2 is described below in greater detail, using Figure 2. Fixing the fastening tower 6, 8 at the annular-shaped section 5 and fixing the fastening tower 9 at the fixing element 10 respectively take place congruently. A smaller or larger number of fastening towers can be provided depending on the pre-determined screw-on map.
Figure 2 illustrates an extracted section along the line demarcated with II in Figure 1. Corresponding elements are furnished with congruent reference signs in all other figures which renders a repeat description superfluous.
Fastening tower 7 has a projection 20 which meshes with the groove 21 designed at the annular-shaped section 5 of the casing 2. The groove 21 is thereby designed at the periphery at the annular-shaped section 5. The fastening tower 7 can thus be moved in a peripheral manner from its fastening at the annular-shaped section 5 in order to establish a position that corresponds to the pre-determined screw-on map. Once in the desired position, additional linking of the fastening tower 7 to the annular-shaped section 5 of the casing 2 of the transmission-propulsion unit 1 takes place by means of a welded joint that is formed by a welding seam 22. Linking the fastening tower 7 and the casing 2 results from a linking combination that takes place by the projection 20 meshing with the groove 21 and the linking that is provided by the welding seam 22.
Alternatively, projection 20 and groove 21 can also be designed in such a manner that the fastening tower 7 engages with the annular-shaped section 5 when affixing same to the casing 2 which ensures reliable linking. The additional welding seam 22 can be dispensed with in this case.

Over and above this, the fastening tower 7 has a stepped bore 23 which is provided to fix the fastening tower 7 with a screw to a structure. The structure could be e.g. a car body component or a part of the seat construction.
Fastening of the transmission-propulsion unit 1 is provided by screwing the corresponding fastening tower 6, 8, 9 fixed to the casing 2 and the fastening tower 7 that has just been described in detail, to the structure.
Figure. 3 illustrates that section demarcated with III in Figure 2 of the transmission-propulsion unit in accordance with the invention, according to a second exemplary embodiment of the invention. The fastening tower 7 in this exemplary embodiment is linked by a screw fastening to the annular-shaped section 5 of the transmission case 3 of the casing 2 of the transmission-propulsion unit 1. A recess 25 is provided for this in fastening tower 7, into which a projection 26 of the annular-shaped section 5 of the casing 2 can be brought. Apart from this the fastening tower 7 has a bore 27 and a threaded hole 28. Furthermore, the projection 26 of the casing 2 has a bore 29. The screw thread section 31 of the screw 30 can be screwed into the threaded hole 28 though bore 27 in the fastening tower 7 and bore 29 in projection 26. Once in the screwed-in position, pulling the projection 26 of the casing 2 out from the recess 25 of the fastening tower 7 is prevented. A detachable link is provided in this manner between the fastening tower 7 and the transmission case 3 of the casing 2.
Alternatively, a recess corresponding to recess 25 can also be designed in the annular-shaped section 5 of the casing and a projection designed at the fastening tower 7 that corresponds to projection 26 in order to affix the fastening tower 7 to the annular-shaped section 5. In this case, the screw 30 is screwed in to the annular-shaped section 5.

Figure 4 illustrates that section demarcated with III in Figure 2 in accordance with the third exemplary embodiment of the invention. In this exemplary embodiment, the fastening tower 7 is linked to the annular-shaped section 5 of the transmission case 3 of the casing 2 by a dovetail link. A dovetail-shaped groove 35 is provided for this purpose in the fastening tower 7 and the annular-shaped section 5 has a dovetail-shaped projection 36 that can be brought into the groove 35. In order to enable raising the fastening tower 7 on the projection 36 of the annular-shaped section 5, the projection 36 is built to be non-continuous at the periphery. The dovetail link illustrated in Figure 4 can also be combined with the welded joint illustrated in Figure 2 by providing an additional welding seam preferably in region 37 and/or in region 38.
Alternative to the dovetail link illustrated in Figure 4, a dovetail-shaped groove corresponding to groove 35 can also be designed at the annular-shaped section 5 of the casing 2, whereby a projection will then have to be provided at the fastening tower 7 that corresponds to projection 36. In this case, it would be of advantage if the groove is not designed in a dovetail shape but is instead designed to be open at one section at least, in order to make it easier to bring the fastening tower 7 into the groove of the annular-shaped section 5. The fastening tower 7 can then be moved into the required position in the peripheral direction.
* Figure 5 illustrates fastening towers 6, 7 8 that have a common base plate 40 in
accordance with the fourth exemplary embodiment of the invention. The common base plate 40 serves to fix the fastening towers 6, 7, 8, to an annular-shaped section 5 of a casing 2, as is illustrated for example in Figure 1. Assembly of the transmission-propulsion unit 1 is simplified by this common base plate 40 since the position of the fastening towers 6, 7, 8 with regard to each other is pre-determinedly fixed and this can be connected jointly to the casing 2 so that fixing of three fastening towers 6, 7, 8 can take place in one assembling step. Fixing the fastening towers 6, 7, 8 to the annular-shaped section 5 of the

casing 2, using the common base plate 40, can be achieved for example in the manner described above by means of Figures 2 to 4.
Fastening tower 7 links, illustrated in Figures 2 to 4, take place at a first juncture 45 that is illustrated in Figure 1. The annular-shaped section 5 is designed in such a manner that fixing can also take place at a second juncture 46. Before fixing the fastening tower 7, there is thus a choice as to whether the fastening tower 7 is to be affixed at the first juncture 45 or at the second juncture 46. This choice enables customisation to varying screw-on maps. In the case of affixing the fastening tower 7 to the annular-shaped section 5 that enables a continuous displacement, customisation can take place to a plurality of screw-on maps. Corresponding to the fixing of the fastening tower 7 to the annular-shaped section 5 already described, fastening towers 6, 8 can also be linked to the annular-shaped section 5 at different junctures. It is particularly advantageous that the fastening towers 6, 7, 8, 9 be uniformly designed so that the fastening tower 6, for example, can be alternatively affixed at the second juncture 46 that is also suitable for fastening tower 7.
The invention is not restricted to the exemplary embodiments described. In the place of the stepped bore 23, in particular, another device can also be provided in order to affix the fastening towers 6, 7, 8, 9 to a structure e.g., the car body of an automobile. The fastening towers 6, 7, 8, 9 can, for example, also be affixed to the structure by a threaded assembly. The term "screw-on map" used in the application is therefore not to be understood in a limited manner with regard to affixing the transmission-propulsion unit 1 by means of fastening towers 6, 7, 8, 9 i.e. that only affixing by means of threaded assembly is possible but that threaded assembly, in particular, is also possible.
