[Industrial applications]

 The present invention relates to a gear device for a tracked vehicle according to the concept of claim 1.

[0002]

[Prior art]

 A gear device of this kind is known from DE-OS 2920820, in which case mainly the improvement of the manufacturing method and partially completed, but a plurality of parts groups to complete the gear device. It is combined with assembling. This modern method of assembly is not only for transmitting and adapting the drive to the gearing, but also for each one-reversing device and steering device as well as the converter and liquid brake and auxiliary drive found in the above specification. The relatively complex gearing in place was recognized for its value and prompted significant improvements. The casing of a gearing of this kind, which requires the mounting of individual parts along the inside and the outside of the casing, connects the parts due to the fixing of the parts and also to the casing and the drive and pressure means. It is therefore a very complex component. Numerous bearing surfaces, bearings and joints are very precisely connected to each other, so that all connections between the assembly of parts and the casing, the drive and the pressure means ensure the perfect assembly and functioning of the gearing. Must be compatible. Moreover, it requires tedious work to manufacture and control the parts group, especially the casing.

[0003]

[The purpose of the device]

 It is an object of the invention to further develop a gear device according to claim 1 and to simplify the work required for its manufacture and assembly.

[0004]

[Means for Solving the Problems]

 This object has been achieved by the features of claim 1. According to the present state of the art in gear systems of this kind, casings require the most complex and very tedious work to manufacture and control, whereas according to the invention, casting production, and in particular finishing and The work required for control is significantly simplified. Because the number of boring and bearing surfaces has been significantly reduced, and the extent of the finished surfaces is so small that the tolerances required for most of those surfaces are maintained. And controls do not cause too much trouble. Manufacture and assembly is significantly simplified by eliminating any bearings of the parts found in the casing for the drive and universal connections of the hydraulic, electrical and drive connections between the parts. It Advantageous features of the invention are described in claims 2-10. By fixing the parts in the bearing-shaped casing via the bearing element, the centering element and the fixing element, the number of surfaces to be finished is reduced and the parts can be optimally arranged in terms of function. A large free space was created. The bearing holes, the centering means and the fixing means, which are arranged concentrically with each other, have basically the same structure, but only the bearing holes are suitable for the respective component groups and gear casings. ing. If the bearing holes of the gear casing are offset in the circumferential direction because of the two component groups that are arranged adjacent to each other in the axial direction, a convenient free space required for assembly is created. As a rule, bearing holes are arranged with the smallest diameter as long as they do not hinder the assembly.

Further, if the bearing element, the centering element and the fixing element are also arranged so as to be displaced in the axial direction, that is, if the bearing hole is not provided on the axial surface, it is optimal in terms of the entire structure space. The gear casing can therefore be kept smaller, which in turn reduces the surface to be finished. The parts arranged coaxially with each other are connected by the opening and the connecting path, but only the opening and the connecting path for the insertion shaft are required in the casing, which is troublesome for manufacturing. There is almost no work to do. It is also possible to axially shift the parts from each other and to drive them together via gears, due to the large free space inside the casing, especially the bearing elements and centering elements for the parts group. It is also possible to engage with the fixing element at the connecting point at the same time. The plug-in socket makes it possible to assemble individual parts very easily in terms of connecting the pressure means. The plug-in connection not only simplifies the assembly, but also avoids the possible misconnection of the connecting parts in the case of a universal connecting tube. Moreover, at the time of removal, the component group can be pulled out from the arranged component group, while the insertion socket of this component group remains so that the connection points of the respective insertion sockets are fixed by the fixing means. It is fixed within.

The convenient and functionally suitable construction of the gear casing in view of the pressure tank has made possible a short bayonet connection. Particularly advantageous are the numerous positions of the gear actuating components and the connection of the gearshift interlocking components and the gear actuating components via the plug-in sockets. This eliminates the universal connecting pipe, the pipe fixed in the casing or the boring for guiding the oil, and as a result simplifies manufacturing and assembling. The misunderstanding of the universal tube known so far does not occur. The fact that the bearing element, the centering element and the fixing element are enlarged by the system for pressure transmission also has the advantage that, for example, pressure can be transmitted from the pressure tank to one of the component groups. Other details of the invention are explained according to the embodiments and the drawings.
