Definitions
- the present invention relates to an arrangement for driving a vehicle wheel with an integrated in a drive axle of a vehicle drive motor according to the closer defined in the preamble of claim 1.
- a wheel drive for a low-floor bus with a wheel axis eccentrically arranged drive motor is known.
- the drive motor drives a gear of a reduction gear as a drive stage in the form of a planetary gear.
- the driven gear is on the one hand in meshing connection with an outer central wheel and on the other hand in meshing connection with other gears, which are also engaged with the outer central wheel.
- the output of this planetary gear is connected to an inner central wheel of a planetary stage of the output stage, the planet carrier forms the output and is connected to the rim of the driven vehicle wheel.
- the invention is based on the object to propose an arrangement of the type described above, which requires the smallest possible space requirement for the same performance. This object is achieved by the features of claim 1, wherein further advantageous embodiments of the dependent claims and the drawings.
- an arrangement for driving a vehicle wheel with at least one drive motor integrated into a drive axle is proposed, which is connected to a drive stage which is coupled to an output stage as a hub side output, wherein a spur gear and a planetary gear as output stage are provided as a drive stage.
- a single-stage spur gear is used, which is the drive side connected to the output shaft of the drive motor and the output side with a central, preferably disposed within the wheel hub drive shaft, which is used to drive the hub side output stage.
- gear types which create a similar space advantage.
- a next development of the invention can provide that, for example, as a planetary drive, a Wolfrom transmission or the like for realizing the ge desired overall ratio is used in the context of the output stage.
- the sun gear of the Wolfromgetriebes be connected to the drive shaft of the drive stage or the spur gear.
- the Wolfrom transmission comprises a plurality of double planets, for example four or the like, wherein the smaller step wheel of each double planet is engaged with the sun gear.
- the smaller step wheels of the double planets mesh simultaneously with a housing-fixed ring gear.
- Each larger stepped wheel of the double planetary gear is engaged with the wheel hub of the vehicle wheel to be driven as the output.
- a multi-stage, for example, two-stage planetary gear is used as the planetary drive.
- the sun gear of the two-stage planetary gear can be connected to the drive shaft of the drive stage or the spur gear.
- the planet gears of the first stage of the planetary gear may mesh with the housing fixed ring gear, wherein the planet carrier of the first stage planet gears is connected to the second stage sun gear.
- the second-stage sun gear meshes with the second-stage planet gears, which in turn engage the housing-fixed ring gear.
- the planet carrier or the web of the planetary gears of the second stage is connected to the wheel hub of the driven vehicle wheel and thus forms the output.
- the planet carrier of the first stage with the sun gear of the second stage form a common component. It is also possible that the planet carrier of the second stage with the hub form a common component. But there are also separate or multi-part components used, which are then connected together accordingly.
- the proposed arrangement for driving a vehicle wheel in a driven vehicle axle of a commercial vehicle such. a bus or the like can be used.
- Figure 1 is a sectional partial view of a first possible embodiment of an arrangement according to the invention
- Figure 2 is a sectional view of a first possible embodiment of a

- Figure 4 is a sectional view of a second possible embodiment of a
- the drive motor 2 which is preferably an electric motor, connected to a drive stage, which is coupled to an output stage as a wheel hub side output.
- a spur gear 3 and as output stage a planetary gear are provided as a drive stage.
- the struck arrangement the smallest possible space, so that the available space can be used on the drive axle 1 for more powerful drive motors 2.
- the driving power of the driven vehicle axle can be increased, so that if necessary, a further driven axle can be saved in the vehicle.
- Figure 1 shows a first embodiment of the arrangement in which the drive motor 2, which is preferably an electric motor, with the example, single-stage helical gear 3 is shown as a drive stage.
- the spur gear 3 is driven by the output shaft 4 of the drive motor 2 and the output side is connected to a central drive shaft 5, which in turn is coupled with the not shown in Figure 1 output stage as radnaben butterer output.
- the spur gear 3 consists of two spur gears. Each of the spur gears is rotatably mounted on a shaft.
- the shaft or the spur gear is mounted on bearings so that one side of the spur gear is free and has no bearing, whereby the axial space is reduced.
- FIG. 2 and 3 is a first embodiment of an output stage of the proposed arrangement.
- the output stage is designed as Wolfromgetriebe 6 in this embodiment.
- the sun gear 7 of the Wolfromgetriebes is connected to the drive shaft 5 not shown in Figure 2.
- the sun gear 7 is engaged with the smaller step wheel 8, 8A of each double planet.
- the smaller stepwheels 8, 8A of the double planets mesh with the ring gear 9 of the Wolfromgetriebes 6.
- the larger step wheels 10,10A, 10B, 10C of each double planet, which are each connected to the smaller step wheels 8, 8A and form a common axis of rotation, are engaged with the wheel hub 1 1 of the driven vehicle wheel and form the output.

- the sun gear 13 meshes with the planetary gears 14, 14A of the first stage, which are simultaneously engaged with the housing-fixed ring gear 15 of the planetary gear 13 in engagement.
- the planet carrier 1 6 of the planetary gears 14, 14 A of the first stage is connected to the sun gear 17 of the second stage or forms with this a common component.
- the sun gear 17 is engaged with the planetary gears 18, 18A of the second stage.
- the planet gears 18, 18A of the second stage also mesh with the housing fixed ring gear 15.
- the planet carrier or the web 19 of the planetary gears 18, 18A of the second stage is connected to the wheel hub 1 1 of the driven vehicle wheel and thus forms the output.
- a drive axle 1 is realized with integrated drive motors for each vehicle wheel, which provides a maximum space for the drive motors due to the small dimensions of the drive stage of each arrangement.
