Abstract

A method for assembling transmissions, in particular automatic transmissions, continuously variable automatic transmissions, dual-clutch transmissions, and direct manual transmissions in series, and assembly directions or a workpiece holder for carrying out the method. In the manufacture and assembling of transmissions in series, it is known practice to allocate the work cycles, consisting of operations which are to be carried out sequentially, in spatial succession to an assembly installation. The sequence of operations thus takes place only in a product-oriented manner, in the technological order, irrespective of whether they are to be carried out manually, by people or mechanically, by installation parts. This results in significant idle and waiting times which incur costs without adding value. The assembly method, according to the invention, is characterized in that, at at least one manned workstation (2, 3), three or more of the components situated on the workpiece holder (WT) are worked on at the same time during a work cycle, and then appropriate measuring, testing, joining, compression, monitoring, lubrication, or screwing operations can be carried out on several components simultaneously at at least one automated station (1, 4).

METHOD FOR MANUFACTURING AND / OR ASSEMBLING PRE-PRODUCTS OR PRODUCTS IN SERIES, METHOD FOR ASSEMBLING TRANSMISSIONS, ASSEMBLY UNIT AND WORKPIECE SUPPORT FOR CARRYING OUT THE PROCESS

The invention relates to a method for manufacturing and / or assembly of precursors or products in series according to the preamble of claim 1. The invention also relates to a manufacturing and assembly plant for carrying out the inventive method, in which man-executable operations as well as by the assembly machine executable operations are arranged and executable in a mixed series, according to the preamble of claim 2.

In the manufacture and assembly of products and precursors in series, such as motor vehicles, engines, units and transmissions, it is known to arrange successively to be executed from work steps also spatially sequentially to a mounting system, the manufacturing and assembly process is broken down into individual work cycles , The majority of these work cycles consist of working steps of manual human activity and of automated mechanical plant operations. There are also work cycles that are completely filled out by human manual activity or completely by the most automated system possible. The working cycles must be as long as possible, since the longest working cycle is decisive for the total cycle time of the system.

The juxtaposition of the work contents is done so far only product-oriented according to the technological order and regardless of whether they are performed manually by people manually or by equipment parts.

Thus, the temporally longest working clock also determines the duration of all other measures. Since time-consuming manual work steps often have to run in addition to short mechanical work steps, especially in the complicated assembly of products and precursors in series, such as motor vehicles, engines, units and gearbox, the corresponding investment stations are only insufficiently utilized in terms of time. The ones with the necessarily Time-consuming manual work entrusted to employees are thereby heavily loaded and such loads inevitably lead to quality-reducing errors. On the other hand, more or less empty and waiting times arise for the other employees employed at the plant, for which costs are incurred but no added value occurs.

Furthermore, preliminary products such as shafts, differentials, couplings, pumps, valve bodies are pre-assembled on individual systems or on so-called pre-assemblies. The devices located there are loaded manually and the automated process is released with 2-hand operation or set in motion by push-buttons in conjunction with a light curtain. In these pre-assemblies, multiple handling of the basic part occurs and the process time of the automatic device work is at the same time idle time and waiting time for the employee, who also incur costs but no value added.

The required different precursors are later combined and assembled together to form a product, motor vehicle, engine, engine or transmission. The quality data of the final assembly is available here, but not the quality data of the individual components or the preliminary products.

There are also a large number of basic studies that are used in assembly planning systems and how industrial robots can be meaningfully integrated into an assembly plant. All, however, are based on the product-oriented principle of origin of the products.

Further, methods and equipment are known in which a plurality of machine work locations are arranged around a human work place, wherein the employee repeatedly performs manual activities on the product, which in the meantime transported in automatic stations, processed there and transported back to the employee and assigned. The assignment can be changed depending on the utilization.

The disadvantage, however, affects the multiple entry and exit of the same product, which is associated with additional waiting times.

The invention is therefore an object of the invention to provide a method for manufacturing and / or assembly of products and precursors in series, such as motor vehicles, engines, units and gearboxes and an assembly system, in which even at different lengths of work within a work cycle and mixed between manual Activity of automatic plant work a uniform stress, in particular of human labor, but also the plant components is possible and as many quality data of the components and precursors can be detected and assigned to the final product.

The focus of this invention is not the product-oriented design of the equipment, but a process-oriented design, in which the actual process and the resulting productivity are in the foreground.

This object is achieved by the method specified in claim 1 and device claim 2 features.

An advantageous embodiment of the assembly system according to the invention is specified in the claims 8 to 14.

By the invention, the idle and waiting times are reduced to a minimum and at the same time the manual power strokes are designed and designed largely at the same time and optimally, resulting in a significantly higher productivity and output of the manufacturing or assembly plant result. At the same time, all quality data of the individual components, the precursors and the end products are available and can be precisely assigned to the respective end product. Another advantage is the cost-effective production of complex and compressed assembly stations and a reduction of investment.

Embodiments of the invention are described below with reference to drawings. Show it:

Fig. 1 is a diagram of the inventive plant for the production of several, identical or different precursors or products.

Fig. 2 is a schematic of the manual and automatic cycle times for 3 precursors.

Fig. 3 shows the division and shares between human manual activity and automated mechanical work of a manufacturing and assembly process for the system of FIG. 1 with one person per manual power stroke. Fig. 4 shows the division of the proportions between human manual activity and automated mechanical work of a manufacturing and assembly process for the system of FIG. 1 for increased production with several people per manual power stroke.

Fig. 5 shows the division of the proportions between human manual activity and mechanically automated work of a manufacturing and assembly process for the system of FIG. 1 with one person per manual power stroke and production of 2 identical precursors or products.

Fig. 2 shows the working cycles of 3 precursors or products (V1, V2, V3) at 3 different pre-assembly systems. The pre-product or product (V1) requires time-varying manual activities (m1 to m4). The inflow and outflow times (ev) of the precursors or products lead to significant idle and waiting times. Between the manual activities, automated plant activities (a) are temporarily stored. Manual work (m5 to m9) of different lengths is necessary for the precursor or product (V2). The inflow and outflow times (ev) of the precursors or products also lead to significant idle and waiting times. Between the manual activities, automated plant activities (a) are temporarily stored. The pre-product or product (V3) requires various manual activities (m10 to m13) of varying lengths of time. The inflow and outflow times (ev) of the precursors or products also lead to significant idle and waiting times. Between the manual activities, automated investment activities (a) are temporarily stored.

In addition to the empty and waiting times, the individual primary products or products must be traded multiple times. The manual working cycle (m4) determines the cycle time of the plant of the precursor or product (V1), the manual cycle (m5) determines the cycle time of the plant of the precursor or product (V2), the manual cycle (m11) determines the cycle time of the plant Pre-product or products (V3). Overall, this arrangement results in 13 manual work cycles with one employee each and 13 automatic stations (a) and a total of 13 run-in and run-out times (ev) of the preliminary products or products (V1, V2, V3) and a considerable idle and waiting time of the employees ( m1, m2, m3, m6, m7, mδ, m9, m10, m12, m13).

3 shows the working cycles of the 3 precursors or products (V1, V2, V3) according to the inventive method, occupying one manual manual stroke per person. The manual working cycle (mn1) includes activities on the preliminary products (V1 and V2), the manual power cycle (mn2) includes activities on the primary products (V1, V2 and V3), the manual power cycle (mn3) includes activities on the primary products (V2 and V3), the manual power cycle (mn4) includes activities on the primary products (V1, V2 and V3), the manual working cycle (mn5) also includes activities on the precursors (V1, V2 and V3). Automated plant activities are temporarily stored between manual activities. The run-in and run-out times (ev) of the precursors or products have been significantly reduced by the simultaneous activities on all three precursors or products, since they occur only once before each automatic station (on). The work contents are determined in such a way that the working cycles of the manual activities (mn1 to mn5) harmonize and are of equal length in time.

Overall, the inventive arrangement 5 manual work cycles with one employee and 5 automatic stations (on) and a total of 5 entry and exit times (ev) of the precursors or products (vi, V2, V3). The employees (mn1 to mn5) are busy at the same time.

4 shows the working cycles of the 3 precursors or products (V1, V2, V3) according to the inventive method with occupation of several persons per fixed manual working cycle. The manual working cycle (mn1 + 2) includes activities on the preliminary products (V1 and V2), the manual working cycle (mn3 + 4) includes activities on the preliminary products (V1, V2 and V3), the manual working cycle (mn5 + 6) includes activities on the precursors (V2 and V3), the manual power stroke (mn7 + 8) includes activities on the precursors (V1, V2 and V3), the manual power stroke (mn9 + 10) also includes activities on the precursors (V1, V2 and V3 ). Automated plant activities are temporarily stored between manual activities. The run-in and run-out times (ev) of the precursors or products have been significantly reduced by the simultaneous activities on all three precursors or products, since they occur only once before each automatic station (on). The work contents are determined in such a way that the working cycles of the manual activities (mn1 + 2 to mn9 + 10) harmonize and have the same length of time. Overall, the inventive arrangement 5 manual work cycles with 2 or more employees and 5 automatic stations (on) and a total of 5 entry and exit times (ev) of the precursors or products (V1, V2, V3). The employees (mn1 + 2 to mn9 + 10) are equally utilized.

5 shows the working cycles 3 of the same precursors or products (V2) according to the inventive method with occupation of one person per specified manual working cycle. The manual working cycle (mn1) involves activities of an intermediate product, the manual working cycle (mn2) includes activities on two primary products, the manual cycle (mn3) includes activities on two primary products, the manual cycle (mn4) includes activities on three intermediate products, the manual cycle (mn5) includes activities on two intermediate products, the manual cycle (mn6 ) includes activities on two precursors, the manual working cycle (mn7) includes activities on three precursors. Automated plant activities are temporarily stored between manual activities. The run-in and run-out times (ev) of the precursors or products have been significantly reduced by the simultaneous activities on all three precursors or products, since they occur only once before each automatic station (on). The work contents are determined so that the working cycles of the manual activities (mn1 to mn7) harmonize and are as long as possible in terms of time. Overall, the inventive arrangement 7 manual work cycles with one employee and 7 automatic stations (on) and a total of 7 inflow and outflow times (ev) of the precursors or products (V2). The employees (mn2 to mn6) are equally utilized. Only the employees (mn1 and mn6) have smaller empty and waiting tents. Compared with Fig. 2, the application has approximately tripled with the use of 2 additional employees and 2 additional automatic stations.

In all three variants (FIGS. 3, 4 and 5), there is a considerable reduction of the work cycles and the idle and waiting times and a reduction in the manual and automatic stations of the production and / or assembly plant. The productivity is increased enormously and the output can be significantly increased with less labor input (as in Fig. 2).

1 shows a diagram of a production and / or assembly plant for the production and / or assembly of precursors or products according to the inventive method. The production and assembly plant consists of automatic stations (1 and 4) with working cycles from mechanical automated plant work and manual workplaces (2 and 3) with working cycles from manual human activity. According to the invention, at the automatic stations (1 and 4) and the manual workstations (2 and 3), work steps are carried out simultaneously on a plurality of precursors or products (a, b, c) within a fixed work cycle, wherein the technological predetermined sequence of the precursors or products (V1, V2, V3) is not here in the foreground, but the manufacturing or assembly process as a whole, which can be optimally determined because it can be worked on several precursors or products (V1, V2, V3) and each resulting technologically caused empty - and waiting times of a precursor or product (V1, V2, V3) filled with work on other precursors or products (V1, V2, V3) and compensated can be. According to the invention, at a work location (2), from a series of possible work steps, so many work steps are concentrated until the predetermined cycle time of the overall system has been reached. Such operations may consist in: selection of predetermined parts; insert parts, screws, washers, circlips, pins, gaskets, gaskets and subassemblies; applying sealants; measure, check and control given characteristics and the like. The machine-executable work steps lie outside the area of the employee's workstations (2) in automatic stations (1 and 4). The precursors and products are transported by known means such as roller conveyors, plate conveyors, overhead conveyors, chains or the like and the jobs of employees (2) and the automatic stations (1 and 4) are connected thereto, the precursors or products also on in itself clamped known workpiece carriers and can be transported together with them. It is furthermore a feature of the invention to configure the automatic stations (1 and 4) so that they can work simultaneously on all intermediate products or products (V1, V2, V3) and via corresponding receptacles for measuring, pressing, screwdriving , Testing, control, joining and other means.

Another feature of the invention is when using workpiece carriers (W) the possibility of receiving manufacturing parts (d), which are required for the manufacture and assembly of the precursors or products (V1, V2, V3) and thus within the manufacturing and assembly plant with or tested can be controlled.

Another feature of the invention is when using workpiece carriers (W) with data carriers or by machine control recording the quality data of all manufacturing parts (d) and the quality data of the precursors and products (V1, V2, V3) and all done at the manufacturing and assembly plant Work steps and the merging of all data to the final product.

If a higher production is required, then it requires no special plant engineering change in the system according to the invention, since only the second workstation (3) occupied and a portion of the steps of the manual workstation (2) on two jobs (2 and 3) are divided. The invention also relates to a method for mounting gearboxes, in particular of automatic transmissions and continuously variable automatic transmissions in series according to the preamble of claim 16. The invention also relates to an assembly system for carrying out the inventive method, in which man-executable operations as well as by the assembly machine-executable Work steps arranged in a mixed row and on the workpiece carrier (WT) executable, according to the preamble of claim 17.

In the assembly of gearboxes, in particular of automatic transmissions and continuously variable automatic transmissions in series, it is known to arrange the successive work steps to be performed from work steps also spatially successively on an assembly plant, wherein the manufacturing and assembly process is broken down into individual work cycles. The majority of these work cycles consist of work steps of human janual activity and of steps of automatic automated plant work. There are also work cycles that are completely filled in by human manual activity or completely by automated mechanical equipment work. The working cycles must be as long as possible, since the longest working cycle is decisive for the total cycle time of the system. The juxtaposition of the work contents is done so far only product-oriented according to the technological order and regardless of whether they are performed manually by people manually or by equipment parts. Thus, the temporally longest working clock also determines the duration of all other measures.

Since, in particular in the complicated assembly of gearboxes, especially automatic transmissions and continuously variable automatic transmissions often time-consuming manual work steps must run in addition to short mechanical work steps, the corresponding investment stations are used inadequate time.

The employees entrusted with the necessarily time-consuming manual work steps are subject to high loads and such loads inevitably lead to quality-reducing errors. On the other hand, more or less empty and waiting times arise for the other employees employed at the plant, for which costs are incurred but no added value occurs.

In addition, components such as planetary carrier, clutches, covers, fins, pumps, input shafts, pulley sets, drive shafts, output shafts, differential, to individual Plants or preassembled on so-called pre-assemblies or pre-strip stations. The devices located there are loaded manually and the automated process is released with 2-hand operation or set in motion by push-buttons in conjunction with a light curtain. In these pre-assemblies, multiple handling of the basic part occurs and the process time of the automatic device work is at the same time idle time and waiting time for the employee, who also incur costs but no value added.

The required different components such as planetary carrier, clutches, covers, fins, pumps, input shafts, pulley sets, drive shafts, output shafts, differentials, are transported to an assembly line, merged there and assembled together to form a gearbox. Here are the quality data of the final assembly available, but not the quality data of the already pre-assembled components, such as planetary carriers, couplings, covers, fins, pumps, input shafts, pulley sets, drive shafts, output shafts and differentials.

Another problem and a cost factor are at different pre-assemblies, which are equipped with interlinking equipment, the different linkage systems and the workpiece carriers transported there, for the individual components, such as planetary carriers, clutches, covers, fins, pumps, input shafts, pulley sets, drive shafts, output shafts and differentials are custom made. Thus, for the production of a gearbox and the pre-assembly of components such as planetary carriers, clutches, covers, fins, pumps, input shafts, pulley sets, drive shafts, output shafts and differentials often result in more than 5 workpiece carrier types, interlinking equipment and assembly equipment. Due to the separate pre-assemblies it comes to a high control effort, since the pre-assembly parts, such as planet carrier, clutches, covers, fins, pumps, input shafts, pulley sets, drive shafts, output shafts and differentials must also be pre-assembled in different variants and these match the final assembly line must be merged to a specific type of transmission. Faulty control is common because a single wrong or missing component, such as planetary carriers, clutches, covers, fins, pumps, input shafts, pulley sets, drive shafts, output shafts, and differentials, leads to end-of-assembly assembly stall and significant downtime.

There are already a large number of basic investigations that find their application in assembly planning systems and how industrial robots make sense in one Assembly system can be integrated. All, however, are based on the product-oriented principle of origin of the products.

The invention is therefore an object of the invention to provide a method for mounting gearboxes, in particular automatic transmissions and continuously variable automatic transmissions in series and an assembly plant in which even with different lengths of work within a work cycle and mixed between manual activity and automatic investment work a uniform Stress, in particular human labor, but also the system components is possible and as many quality data of the components, such as planet carrier, clutches, covers, fins, pumps, input shafts, pulley sets, drive shafts, output shafts and differential, detected and assigned to the finished transmission.

In the foreground of this invention is not the production-oriented design of the plants, but a process-oriented design, in which the actual process and the resulting productivity in the foreground.

This object is achieved by the method specified in claim 16 and in the device claims 17 features.

An advantageous embodiment of the workpiece carrier according to the invention is specified in the subclaims.

By the invention, the idle, waiting and loss times are reduced to a minimum and at the same time the manual power strokes are designed and designed largely at the same time and optimally, resulting in a considerable higher productivity and output of the entire assembly plant result. The handling of individual components, such as planetary carriers, Clutches, covers, vanes, pumps, input shafts, pulley sets, drive shafts, output shafts and differentials and their transport are also significantly reduced. At the same time, all quality data of the individual components, such as planetary carriers, couplings, covers, fins, pumps, input shafts, pulley sets, drive shafts, output shafts and differentials and the transmission are available and can be assigned to the respective finished transmission exactly. Another advantage is the cost-effective production of the complex and compressed assembly stations, reduction of the workpiece carriers and chaining variants and a reduction in investment.

Fig. 7 is a diagram of the inventive method for the production of several components simultaneously, such as planet carrier, clutches, covers, fins, pumps, input shafts, pulley sets, drive shafts, output shafts and differentials, for the production of transmissions, especially automatic transmissions and continuously variable automatic transmissions in series.

Fig. 6 shows an example of a conventional assembly plant (F), where the individual components, such as planet carrier, clutches, covers, fins, pumps, input shafts, pulley sets, drive shafts, output shafts and differential are assembled, which at so-called pre-assemblies or Vorbandstationen (A, B , C, D, E) before they are delivered as sub assemblies to the assembly line or assembly plant. On pre-assembly (A), planetary carriers are mounted, clutches are mounted on pre-assembly (B), disc sets are mounted on pre-assembly (C), pumps are mounted on pre-assembly (D), input shafts are mounted on pre-assembly (E). The pre-assembled planetary carriers, couplings, covers, vanes, pumps, input shafts, pulley sets, drive shafts, output shafts, differentials are then delivered from the pre-assemblies (A, B, C, D ₁ E) to the assembly line or assembly system (F). This results in considerable loss times due to multiple handling and transport of the components. So the basic parts are already traded several times before they are even ready for assembly.

Fig. 7 shows a schematic of the inventive method for the production of simultaneously several components, such as planetary carriers, clutches, covers, fins, pumps, input shafts, pulley sets, drive shafts, output shafts and differentials, for the production of transmissions, in particular of automatic transmissions and continuously variable automatic transmissions in series , here the pre-assembly line (G) according to the inventive method. The manufacturing and assembly process of the components, such as planet carrier, clutches, covers, fins, pumps, input shafts, pulley sets, drive shafts, output shafts and differentials takes place here on an assembly plant (G) in such a way that the components of the transmission on one Constructed workpiece carrier (WT) are transported together. The manufacturing and Mbntagevorgang takes place in the manner that at several workstations simultaneously on several components, such as planetary gear, clutches, covers, fins, pumps, input shafts, pulley sets, drive shafts, output shafts and differentials is worked. In the following automatic stations, couplings, covers, lamellas, pumps, input shafts, pulley sets, drive shafts, output shafts and differentials are simultaneously machined automatically on the workpiece carrier (WT) on several of the components, such as planetary carriers. After the components have been preassembled, the workpiece carriers (WT) are directed into a decoupling module (H) to compensate for jerky or uneven production of the pre-assembly line (G) and the final assembly line (K) and to store workpiece carriers (WT) as needed.

At point (M), components such as planetary carriers, couplings, covers, vanes, pumps, input tangs, pulley sets, drive shafts, output shafts and differentials are transferred to the workpiece carrier of the final assembly line (G) and at the same time all quality - related information and data relating to the The final assembly line (G) has workstations (L) and automatic stations (N), which are only used for certain types, such as all-wheel versions, and where components such as end covers and end shafts are pre-assembled be mounted with the gearbox. For other types, the workstations (L) and automatic stations (N) are not operated and the workpiece carriers are automatically transported on.

At the end of the final assembly line, the finished gearboxes are checked for function and noise on gearbox test stands in a test field or test line (P).

According to the invention so many steps are concentrated at a work place from a number of possible steps of several components, such as planet carrier, clutches, covers, fins, pumps, input shafts, pulley sets, drive shafts, output shafts and differentials until the predetermined cycle time of the entire system is reached , Such operations may consist in: selection of predetermined parts; insert parts, screws, washers, circlips, pins, gaskets, gaskets and subassemblies; applying sealants; measure, check and control given characteristics and the like. The machine-executable work steps are outside the range of the employee's workstations in automatic stations. The components are transported on workpiece carriers (WT) with known funding, such as roller conveyors, plate conveyors, links or the like, and the jobs of employees and the automatic stations are connected.

The required assembly systems (G) and (K) are equipped with elevators (R) with bridging device (S), where the workpiece carriers are transported via a chain on a stage, so as to ensure optimum rinsing with the required material and in case of failure Bridging device (S) takes over the transport.

Compared to the conventional mounts (Fig. 1), personnel costs are reduced by approximately 50 percent, whereby the output can be significantly increased by avoiding multiple handling, reducing the loss times and automatic stations with simultaneous multiple operations.

8 shows a schematic of the workpiece carrier (WT) that is designed to simultaneously supply all required components, such as planetary carriers, clutches, covers, fins, pumps, input shafts, pulley sets, drive shafts, output shafts, differentials and transmission housing parts (a, b , c, d, e, f, g, h, k). The workpiece carrier is designed so that it has stiffeners, which make it possible in automatic stations with corresponding stops or counter-holders on several or all components, such as Planet carrier, clutches, covers, fins, pumps, input shafts, pulley sets, drive shafts, output shafts, differentials and gear housing parts simultaneously assembly work, such as measuring, testing, joining, pressing, checking, screws and the like to perform.

It is also a feature of the invention that all appropriate work for measuring, pressing, screwing, testing, checking, joining, oiling and other assembly operations on the workpiece carrier (WT) can be done.

Another feature of the invention is that the workpiece carriers (WT) are provided with data carriers, the recording of the quality data of all manufacturing parts and the quality data of components such as planetary carriers, couplings, covers, fins, pumps, input shafts, pulley sets, drive shafts, output shafts, Allow differential and gear housing parts and all done at the manufacturing and assembly plant operations and assign them to the transmission exactly.

A further feature of the invention is that the automatic stations of the assembly plant can be standardized by the design of the workpiece carrier (WT) in order to produce these cost-effectively.

Fig. 9 shows a schematic and layout of the inventive method in the arrangement of the pre-assembly (G) and final assembly (K) side by side in longitudinal form.

Fig. 10 shows a schematic and layout of the inventive method in the arrangement of pre-assembly (G) between the final assembly (K) in L-shape.

Fig. 11 shows a schematic and layout of the inventive method in the arrangement of pre-assembly (G) in addition to the final assembly (K) in L-shape.

Fig. 12 shows a diagram of the elevator. The invention also relates to a method for mounting gearboxes, in particular double-clutch transmissions and direct-shift transmissions in series according to the preamble of claim 39. The invention also relates to a workpiece carrier (WT) for carrying out the inventive method, in which human executable steps and by the assembly system arranged mechanically machinable operations in a mixed row and all on the workpiece carrier (WT) are executable, according to the preamble of claim 40th

In the assembly of gearboxes, in particular of dual clutch transmissions and direct shift transmissions in series, it is known to arrange successively executed, consisting of steps work cycles also spatially successively on a mounting system, the manufacturing and assembly process is broken down into individual work cycles. The majority of these work cycles consist of steps of human manual activity and of automated mechanical plant work. There are also work cycles that are completely filled in by human manual activity or completely by automated mechanical equipment work. The working cycles must be as long as possible, since the longest working cycle is decisive for the total cycle time of the system. The juxtaposition of the work contents is done so far only product-oriented according to the technological order and regardless of whether they are performed manually by people manually or by equipment parts.

Thus, the temporally longest working clock also determines the duration of all other measures.

Since, in particular in the complicated assembly of gearboxes, in particular dual-clutch transmissions and direct-shift transmissions, time-consuming manual worksteps often have to run in addition to short mechanical worksteps, the corresponding equipment stations are only inadequately exploited in terms of time.

The employees entrusted with the necessarily time-consuming manual work steps are subject to high loads and such loads inevitably lead to quality-reducing errors. On the other hand, more or less empty and waiting times arise for the other employees employed at the plant, for which costs are incurred but no added value occurs. Furthermore, drive shafts, output shafts, return shafts, pump shafts, differential, synchronizer bodies, flange shafts, are pre-assembled on individual systems or on so-called pre-assemblies or pre-belt stations. The devices located there are loaded manually and the automated process is released with 2-hand operation or set in motion by push buttons in conjunction with a light curtain. In these pre-assemblies, multiple handling of the basic part occurs and the process time of the automatic device work is at the same time idle time and waiting time for the employee, who also incur costs but no value added.

The required different drive shafts, output shafts, pump shafts, return shafts, differential, synchronizer body, flange shafts, are later brought together and assembled into a gearbox. Here are the quality data of the final assembly available, but not the quality data of the already pre-assembled drive shafts, output shafts, pump shafts, return shafts, differential, synchronizer body, flange shafts.

Further, methods and equipment are known in which a plurality of machine workplaces are arranged around a human work place, the employee performs several times manual activities on the product, which in the meantime transported in automatic stations, processed there and again transported to the employee and assigned. The assignment can be changed depending on the utilization.

The invention is therefore an object of the invention to provide a method for mounting gearboxes, in particular of dual clutch transmissions and direct shift transmissions in series and a workpiece carrier, in which even with different lengths of work within a work cycle and mixed between manual activity and automatic investment work uniform stress , In particular, the human labor, but also the plant parts is possible and as many quality data of the components, such as Drive shafts, output shafts, pump shafts, return shafts, differential, synchronizer body, flange shafts, can be detected and assigned to the finished gearbox.

An advantageous embodiment of the workpiece carrier according to the invention is specified in the claims 6 and 7.

By the invention, the idle and waiting and loss times are reduced to a minimum and at the same time the manual power strokes are designed and designed largely at the same time and optimally, resulting in a significantly higher productivity and output of the entire assembly plant result. At the same time, all quality data of the individual components, the drive shafts, output shafts, pump shafts, return shafts, differential, synchronizer body, flange shafts, and the gearbox are available and can be assigned to the respective finished gearbox exactly. Another advantage is the cost-effective production of complex and compressed assembly stations and a reduction of investment.

13 shows a conventional assembly plant (7), in which individual components, such as differential (A) ₁ drive shafts (B) and output shafts (C) on so-called pre-assemblies or pre-strip stations (1, 2, 3, 4, 5 and 6) before they are delivered to the assembly line or subassembly as subassemblies. On pre-assembly (1), the differential (a) is assembled with component or gear (b) and passed on to pre-assembly (2), where other components such as bearings (c) are mounted and pressed. The pre-assembled differential (A) is then delivered to the assembly line or assembly plant. On pre-assembly (3) the drive shafts (d and f) with bearing or gear (e) are mounted and passed on to pre-assembly (4), where further components such as bearings (g) are mounted and pressed. The preassembled drive shafts (B) are then delivered to the assembly line or assembly plant.
