    专利说明:

    Thus, the two cylindrical gears no longer need to be aligned for a precise gear engagement, instead only the plug connection between the drive module of the body module and the first cylindrical gear needs to be joined. By drive joint is meant a drive joint of the body module, which drives the basic transmission or oil cylindrical gear stage of the pump. The insertion into each other for the two parts of the insertion connection (threading) is not critical. Damage to the cylindrical gears of the cylindrical gear stage is excluded during assembly.
    According to a preferred embodiment, the plug-in connection is designed as a carrier gear, i.e. the drive joint of the body module has an outer driver tooth and the first, cylindrical gear has an inner driver tooth, which is joined in the axial direction with the outer driver tooth. Threading of both parts of the carrier gear is possible without problems.
    According to a further preferred embodiment, the first cylindrical gear is received in a housing part of the basic transmission.
    According to a further preferred embodiment, a shim is arranged between the first, cylindrical gear and the housing part, which on the one hand performs the function of a bearing disc and on the other hand the function of a further centering of the first, cylindrical gear relative to the basic transmission, so that a connecting threading of the plug-in connection is possible and thereby facilitates assembly.
    According to a further preferred embodiment, the washer has lubrication grooves on the front side facing the first, cylindrical gear, which improves the lubrication between the flat surfaces of the first, cylindrical gear and the washer. Thereby an axially acting sliding bearing is obtained.
    According to a further preferred embodiment, the shim is provided with mounting studs on the front side facing the casing part, which act for fastening the shim to the casing. As a result, it is possible to fix the spacer washer in advance on the housing part and to act as a stop for the first cylindrical gear during assembly.
    According to a further preferred embodiment, the liner has a centering band with an insertion closure. This facilitates and supports the assembly and positioning of the first, cylindrical gear in the housing part of the basic transmission. The first, cylindrical gear is thereby centered in the basic transmission, i.e. aligned coaxially with the main shaft. This facilitates the connecting threading of the plug-in connection. According to a further preferred embodiment, the body module is designed as a converter module, which comprises a hydrodynamic converter as a starting aid for the basic transmission. The transducer module and the basic transmission are prefabricated as separate design units, which are then mounted to a design unit. In this case, the first, cylindrical gear is no longer pre-assembled at the transducer node, but is already arranged before mounting in the basic transmission and is brought into gear engagement with the second, cylindrical gear.
    According to a further preferred embodiment, the body module is designed as a hybrid module, which comprises an electric motor as well as a planetary gear arranged between the electric motor and the basic transmission. The planetary gearbox takes over the torque and power transmission between the internal combustion engine and / or electric motor on the one hand and the basic transmission on the other.
    According to a further preferred embodiment, the hybrid module has a sealing element on its circumference, which is preferably designed as an O-ring and seals the hybrid module against one end of the basic transmission. The insertion of the O-ring seal is part of the assembly process.
    According to a further preferred embodiment, the drive joint of the hybrid module is designed as a planet carrier or bridge of the planetary gear. The planetary gearbox thereby drives the oil pump in the basic transmission via the planet carrier.
    According to a further aspect of the invention, in a mounting method the body module and the basic transmission are arranged such that in a first method step the first, cylindrical gear is positioned in the basic transmission and is engaged in gear engagement with the second, cylindrical gear. This eliminates the problematic alignment of the two cylindrical gears and bringing them into engagement during assembly. Consequently, no damage can occur to the cylindrical gears during assembly, as the two cylindrical gears of the cylindrical gear stage are already in gear engagement with each other even before the assembly of the superstructure module and basic transmission.
    According to a further preferred method variant, a shim is inserted into a housing part of the basic transmission for the positioning of the first, cylindrical gear in the basic transmission, whereby a centering of the first, cylindrical gear is possible. At the same time, the cylindrical gear arranged in the basic transmission receives a contact surface, which acts as a stop during the connecting formation of the plug-in connection. According to a further preferred method variant, in a second method step, the body module and the hybrid module are joined together in the direction of the main axis - at the same time the drive joint and the planet carrier, respectively, are actuated in the first, cylindrical gear and form a plug connection. If, on occurrence, a tooth-to-tooth position should arise during the entrainment of the plug-in connection, this can be lifted by a slight rotation.
    According to a further preferred embodiment variant, in a third method step, i.e. in the case of continued mounting movement in the axial direction, the sealing element, i.e. the slide of the basic transmission fl is inserted over the O-ring arranged in the hybrid module In this case, the plug-in connection is already in place, ie the carrier gear is in mutual engagement. It is thus important that the threading of the plug connection takes place first and that the joining of the O-ring seal takes place in connection therewith. In this way, when the plug-in connection is made, it can be determined whether there is a tooth-to-tooth position to begin with, which in that case can be quickly corrected.
    An embodiment of the invention is shown in the drawings and is described in more detail below, wherein further features and / or advantages appear from the description and / or the drawing. Fig. 1 shows a hybrid module and a basic transmission according to the prior art before assembly, Fig. 2 a basic transmission before and after assembly according to the invention, Fig. 3 an axial section of the hybrid module during assembly, Fig. 4 an enlarged view of a plug connection between the first , the cylindrical gear and the planet carrier, Fig. 5 a shim in two views, and Fig. 6 a transducer module according to the prior art.
    Fig. 1 shows a basic transmission 1 and a hybrid module 2 as prefabricated construction units before their assembly - according to the prior art. The basic transmission 1 can be designed as a step machine or gear transmission and can be built into a motor vehicle's driveline. The basic transmission 1 has an invisible oil pump, which can be driven by an axially displaced pump shaft 3. The hybrid module 2, generally also referred to as the superstructure module 2, comprises an electric motor (not shown), which can be arranged between an internal combustion engine (not shown) of the motor vehicle and the basic transmission 1. On the hybrid module 2, a first, cylindrical gear 4 is pre-assembled, while a second, cylindrical gear 5 is attached to the basic transmission 1 on the pump shaft 3. During the mounting of the hybrid module 2 and the basic transmission 1, the two structural members are aligned. Units 1, 2 coaxially and mounted in the axial direction. In this case, the first, cylindrical gear 4 must be aligned so that both teeth engage each other, ie that one tooth of the first, cylindrical gear 4 engages in a gear slot of the second, cylindrical gear 5. The hybrid module 2 also has a sealing element 6 designed as an O-ring, which during the assembly of the two construction units 1, 2 is joined to one end of the basic transmission. When the two cylindrical gears 4, 5 engage, which in operation form a cylindrical gear stage for driving the oil pump, there can be problems in a tooth-to-tooth position.
    Fig. 2 shows an assembly according to the invention of the first, cylindrical gear 4, the basic transmission 1 being shown on the left side of the drawing before the assembly of the first, cylindrical gear 4 and on the right drawing side after the assembly of the first, cylindrical gear 4. In Fig. 1 and Fig. 2, the same reference numerals are used for the same parts. The basic transmission 1 shows on the right side of Fig. 2 that the first, cylindrical gear 4 is placed coaxially in the basic transmission 1 and is in gear engagement with the second, cylindrical gear 5. The positioning of the first, cylindrical gear 4 in the basic transmission 1 and the alignment with the gearing of the second, cylindrical gear 5 is referred to as the first method step in an assembly method. In addition to or before the positioning of the first, cylindrical gear 4, a spacer 7 is mounted between the first, cylindrical gear 4 and the basic transmission 1.
    Fig. 3 shows an axial section through the hybrid module 2 and through the partially shown basic transmission 1. The hybrid module 2 and the basic transmission 1 have a common main axis a and are joined in the direction of the main axis a. The hybrid module 2 has a circumferential shaft 2a, and the basic transmission 1 has a circumferential la end 1a, which is connected to fl end 2a. In the area of the two ends 1a, 2a, the sealing element 6 is designed as an O-ring. Fig. 3 shows the hybrid module 2 and the basic transmission 1 in an intermediate position, i.e. at assembly not yet completed. The hybrid module 2 comprises an electric motor 8 and a planetary gear 9, which transmits the power from the electric motor and / or the power from an internal combustion engine (not shown) of the motor vehicle. The planetary gear 9 has a planet carrier 10 on the driven side, also commonly called a drive joint, which has a section designed as a neck 10a with a front surface 10b. In the basic transmission 1 a niche-like designed housing part 11 is arranged, in which the shim 7 (see also Fig. 2) is fi xxed. In addition, the first cylindrical gear 4 is arranged coaxially with the main shaft a and centered relative to the washer 7. The basic transmission 1 and the hybrid module 2 are in a mounting position, which is clarified by a radial plane E, which runs in the same plane as the front surface 10a of the neck section 10a. The neck 10a of the planet carrier 10, which is to be connected via a carrier gear (without reference numeral) to the first, cylindrical gear 4, is still outside the engaging area, but immediately before engagement with each other for the two carrier teeth. On the other hand, the O-ring 6 is still free and has a distance b to an edge of the casing 1a. If in a further movement towards each other for the basic transmission 1 and the hybrid module 2, ie over the plane E, a blockage should occur due to a tooth-to-tooth position, this can be eliminated by a slight rotation and the assembly process is continued until the two carrier teeth completely covers the neck 10a and the first, cylindrical gear 4. During this mounting movement, the shim 7 acts as an axial stop.
    Fig. 4 shows an enlarged view of the connection between the first, cylindrical gear 4 and the neck 10a of the planet carrier 10. The connection is designed as a plug-in connection 12 with a carrier tooth, an outer driver tooth 12a being located on the neck 10a and an inner driver tooth 12b being located in the bore of the first, cylindrical gear 4. In the position shown, the mounting process is completed. , in the sense that the carrier teeth 12 are in constant engagement, i.e. there is a cover over the total axial extent.
    An arrow 13 denotes a centering area, which on the one hand comprises a bore in the housing part 11, on the other hand a centering shoulder on the shim 7 and a centering belt on the first, cylindrical gear 4. Thereby the first, cylindrical gear can 4 is prepared during assembly directed coaxially to the main axis a and for the joining of the plug connection 12.
    Fig. 5 shows the shim 7 in two views, the view on the left side of the drawing showing a first front surface 7a, in which lubrication grooves 7c are incorporated. The first front surface 7a with lubricating grooves 7c abuts the flat surface of the first, cylindrical gear 4. The view of the shim 7 on the right in the drawing shows a second front surface 7b, on which your fastening knobs 7d are arranged distributed on the wire circuit, which act for fastening the shim 7 in the sheath part 11. The shim 7 can consequently be fixed in the sheath part 11. In addition, the washer 7 has a centering band 7e, which - as can be seen from Fig. 4 - acts for the centering of the washer 7 relative to a corresponding bore in the housing part 11. The spacer 7 thus has fl your functions: on the one hand it acts as a stop and bearing writing and on the other hand as a centering aid for the first, cylindrical gear 4 in the housing part 11. Fig. 6 shows a known so-called converter module 14, generally also referred to as a body module. The transducer module 14 comprises - as is known in the art - a hydrodynamic transducer, which can be connected as a starting aid for a basic transmission. In the present case, a first, cylindrical gear 15 is pre-mounted on the driven side of the transducer module 14 and the drive joint, for example welded on, which together with a second cylindrical gear arranged on the base transmission forms a cylindrical gear stage for driving an oil pump. The known mounting takes place in an analogous manner, as described for the known hybrid module according to Fig. 1. The first, cylindrical gear 15 must thus, when mounted with the basic transmission, be aligned with the second, cylindrical gear with respect to their circumferential positions, that the gearing has opportunity to intervene. In order to obviate the associated disadvantages, it is according to the invention arranged at the known transducer 14 that the first, cylindrical gear 15 is not pre-mounted on the transducer module 14, but that before mounting the two construction units positioning they are mounted on the basic transmission and are engaged in gear engagement with the other, cylindrical gear. Thereafter, the drive joint of the transducer module 14 is connected via a plug connection to the first, cylindrical gear, i.e. analogous to the above-described embodiments according to Figs. 2 to 5. Thereby the same advantages as described above are obtained for the hybrid module 2.
