Definitions

  • the invention relates to a drive unit for driving at least one wheel drive shaft, in particular of a wheelset axle, for rail vehicles, in particular having the features from the preamble of claim 1.
  • Drive units for rail vehicles are known in a multiplicity of embodiments. These comprise a driving engine which is coupled to a transmission assembly.
  • the drive of the transmission assembly is formed by a hollow shaft which is coupled via an articulated coupling to the wheel drive shaft, in particular the wheelset axle, in order to compensate the relative movements between the wheelset axle and cross-drive.
  • the driving engine is arranged here in the direct spatial vicinity of the transmission assembly, preferably both—driving engine and transmission assembly—are connected to one another by flanges in the region of their housings. As a result of this measure, only one radial bearing is necessary for the driving engine and a corresponding end shield.
  • the coupling of the drive shaft of the driving engine to the transmission input shaft is carried out by means of what is referred to as a rotationally rigid and radially rigid diaphragm coupling.
  • the transmission assembly itself is usually embodied in two stages or in a single stage with an intermediate wheel.
  • the output gearwheel is seated here on the hollow shaft, said output gearwheel being either coupled fixed in terms of rotation to the hollow shaft or else forming one physical unit with said hollow shaft.
  • the physical unit composed of the driving engine and transmission assembly which is also referred to as an integrated cross-drive, is attached only at three points in the bogey frame with primary suspension. If necessary, a braking system is assigned to the drive unit, the brake disk being arranged on the hollow shaft.
  • the activation elements are arranged in the housing of the transmission assembly.
  • the disadvantage of the previous solution is that, on the one hand, the overall costs for the structural implementation and fabrication are relatively high. Furthermore, in particular for embodiments which are to be used in low-platform vehicles, the available radial and axial installation space is considerably reduced as a result of wheel diameters which are becoming ever smaller while at the same time drive hollow shaft internal diameters are becoming larger owing to the softer suspensions. There is thus no longer sufficient installation space available to arrange the braking system in this region in order to achieve sufficient braking deceleration. Solutions for this are to arrange the braking system at another location or else to do without conventional mechanical braking systems and use other braking systems, for example electrical braking systems, which are however more costly.
  • the invention has therefore been based on the object of developing a drive unit for a wheel drive shaft, in particular a wheelset axle, in particular for the use of rail vehicles of the type mentioned at the beginning, in such a way that sufficient braking deceleration is achieved with simple means and also with an axial and radial installation space which is becoming smaller and smaller.
  • the structural solution is intended here to be defined by a simple embodiment, cost-effective fabrication and mounting.
  • the solution according to the invention is to be applicable in particular for vehicles of the low-platform type.
  • the drive unit for driving at least one wheel drive shaft comprises a cross-drive with a driving engine and a transmission assembly which is coupled thereto.
  • the output of the transmission assembly is embodied as a hollow shaft and is connected to the wheel drive shaft or the wheelset axle via a coupling, in particular an articulated coupling.
  • the braking system comprises two braking subsystems by means of which the entirety of the braking force necessary can be generated by activating two braking subsystems.
  • the solution according to the invention provides the advantage that as a result of the distribution between a plurality of braking systems said braking systems can, in their entirety, be kept respectively smaller in terms of their dimensions in the radial and axial directions and the installation space available can thus be used to an optimum degree.
  • the individual braking subsystems can be arranged. They can either be arranged on the two sides of the transmission assembly, one of the two braking subsystems being arranged between the transmission assembly and the first coupling element of the coupling which is necessary for coupling to the wheelset axle.
  • additional attachment means which take up space, for the elements to be connected to one another have been dispensed with and the entire system has been structurally simplified.
  • the hollow shaft is embodied integrally with at least one of the attachment flanges for one of the braking subsystems.
  • the first coupling part of the articulated coupling is also embodied in one piece with the hollow shaft.
  • the radial installation space necessary for the connecting elements is significantly reduced in comparison with that in embodiments according to the prior art.
  • the solution according to the invention provides the advantage that the available radial and axial installation space resulting from the wheel diameters which are becoming smaller and smaller while at the same time the output hollow shaft internal diameters are becoming larger and larger owing to the softer suspensions is utilized to an optimum degree and at the same makes available the necessary braking deceleration.
  • both braking subsystems between the transmission assembly and articulated coupling.
  • both attachment flanges form one physical unit with the hollow shaft.
  • the transmission housing is embodied in an integral fashion.
  • the hollow shaft is supported by means of a bearing arrangement in the housing of the transmission assembly.
  • the external diameter of the bearings is provided to be identical for all embodiment variants, while adjustment is carried out to the requirements of use by means of variable bearing arrangement internal diameters and thus hollow shaft external diameters.
  • FIG. 1 shows an axial section of a schematic simplified view of the basic design of a drive unit designed according to the invention
  • FIGS. 2 a and 2 b show the coupling of the attachment flanges of the individual braking subsystems to the hollow shaft.
  • FIG. 1 shows a schematic simplified view of the basic design of a drive unit designed according to the invention for driving at least one wheel drive shaft which is coupled to at least one wheel and which is formed by a wheelset axle 3 in the case illustrated.
  • the drive unit 1 comprises an integrated cross-drive 4 .
  • This comprises a driving engine 5 which is coupled to the transmission assembly 6 .
  • the drive shaft 7 of the driving engine 5 is connected fixed in terms of rotation to an input 8 of the transmission assembly 6 , preferably via a coupling element 9 in the form of a diaphragm coupling which is rotationally rigid and embodied so as to be rigid in the radial direction.
  • the transmission assembly 6 comprises an output 10 which is formed by a hollow shaft 11 which encloses the wheelset axle 3 in the circumferential direction and over at least part of its axial extent.
  • Said hollow shaft 11 is connected to the wheelset axle 3 via an articulated coupling 12 .
  • the articulated coupling 12 comprises here a first coupling part 13 and a second coupling part 14 which can be connected to one another in a rotationally elastic fashion.
  • the first coupling part 13 is connected here fixed in terms of rotation to the hollow shaft 11 .
  • the second coupling part 14 is coupled at least indirectly fixed in terms of rotation to the wheelset axle 3 .
  • at least indirectly means that the connection is made directly to the wheelset axle or else via further transmission elements, for example a second coupling level.
  • the hollow shaft 11 and the first coupling part 13 are of integral design.
  • the drive unit 1 comprises a braking system 15 which is preferably embodied in the form of a disk brake unit 16 .
  • the braking system 15 comprises at least two braking subsystems 17 . 1 and 17 . 2 which are each embodied as disk brake systems.
  • the necessary overall braking force is thus generated by two braking subsystems 17 . 1 and 17 . 2 .
  • These comprise here a brake disk 18 . 1 or 18 . 2 which is only indicated and which can be attached to the hollow shaft 11 .
  • the hollow shaft has in each case two attachment flanges 19 . 1 and 19 . 2 which form one physical unit with the hollow shaft 11 , and at least one flange—the attachment flange arranged between the transmission assembly 6 and articulated coupling 12 —is preferably formed with the hollow shaft 11 from one component.
  • the other second attachment flange is attached to the hollow shaft 11 by means of attachment elements.
  • the two attachment flanges 19 . 1 and 19 . 2 are arranged here on both sides of the transmission assembly 6 .
  • the activation elements (not illustrated here) can thus easily be arranged and attached to the housing 20 of the transmission assembly.
  • the integral embodiment of the hollow shaft 11 with the simultaneously integrated attachment flange 19 . 1 and 19 . 2 for the braking subsystems 17 . 1 and 17 . 2 and the fact that the crown gear known from the prior art between the hollow shaft 11 and the first coupling part 13 provides, in addition to more cost-effective fabrication, the advantage of requiring less radial installation space.
  • the driving engine 5 and the transmission assembly 6 are arranged spatially near to one another, preferably connected to one another by flanges in the region of their housings 21 and 20 .
  • the transmission assembly 6 comprises two pairs of spur wheels, a first set of spur wheels 22 and a second set of spur wheels 23 .
  • the first set of spur wheels 22 comprises a spur wheel 24 which is coupled fixed in terms of rotation to the transmission input shaft 8 , the spur wheel 24 either forming one integral assembly with the transmission input shaft 8 or else being connected fixed in terms of rotation to it.
  • the spur wheel 24 intermeshes with a spur wheel 26 which is arranged on an intermediate shaft 25 .
  • a second spur wheel 27 is arranged on the intermediate shaft 25 , said second spur wheel 27 being a component of the second set of spur wheels 23 and intermeshing with a spur wheel 28 which is connected fixed in terms of rotation to the hollow shaft 11 .
  • the hollow shaft 11 and spur wheel 28 are embodied as an integral component.
  • the integral component composed of the hollow shaft 11 , the attachment flange 19 . 2 and the first coupling part 13 , and optionally also the spur wheel 28 can be embodied as a cast part or forged part.
  • the housing 20 of the transmission assembly 6 is embodied in an integral fashion, the bearing arrangement 29 of the hollow shaft 11 in the housing 20 having, in terms of its internal diameter D 28 , a fine gradation with a simultaneous roller bearing external diameter D A28 .
  • This measure provides a very small transmission center, i.e. transmission assembly 6 with a simultaneously high roller bearing service life.
  • inventive solution of the embodiment of the hollow shaft 11 , attachment flange 19 . 2 and of the first coupling part 13 as one integral component can be used for a multiplicity of integrated cross-drives 4 and is not tied to a specific embodiment of the transmission assembly 6 or of the driving engine 5 .
  • Other embodiments which lie within the field of activity of a person skilled in the respective art are also conceivable.
  • the attachment flange 19 . 2 of the second braking system 17 . 2 is embodied in an integral fashion with the hollow shaft 11 .
  • the attachment flange 19 . 1 of the first braking system 17 . 1 is connected, as a separate component, fixed in terms of rotation to the hollow shaft 11 by means of attachment elements 30 , for example in the form of screw elements which are arranged at specific intervals in the circumferential direction of the attachment flange 19 . 1 .
  • a structural embodiment of the connection of the brake disk of the second braking system 17 . 2 to the attachment flange 19 . 2 is illustrated in FIG. 2 a .
  • FIG. 2 b shows a possible structural embodiment of the connection of the brake disk 18 . 1 to the attachment flange 19 . 1 of the first braking subsystem 17 . 1 , and the attachment of the attachment flange 19 . 1 to the hollow shaft 11 .
