- the rim of the on ⁇ drive wheel is typically screwed axially from outside on the drive ⁇ motor of the wheel hub drive. This leads to ei ⁇ ner reduction of the usable space within the drive wheel.
- the present invention has for its object to increase the space within a drive wheel.
- a drive for a motor vehicle in particular for an electric motor vehicle, provided schla ⁇ gene comprising at least one sleeve-shaped rim and an external rotor motor with a rotor, wherein the sleeve-shaped chan- rim by means of a releasable connection directly and torsionally to the rotor oflibraryieriditermo ⁇ is connected.
- the rim of the drive wheel is buildin ⁇ Untitled directly and a torque-locking the rotor of the external-rotor motor.
- a rim spider and a wheel wrench of the drive wheel as provided for example in classic ⁇ rectangular drive concepts omitted.
- a two-piece rim that is, in a rim with a rim and a rim star, the rim star is replaced by the rotor of the external rotor motor.
- the sleeve-shaped rim is directly fixed and a torque-locking by means of a releasable connection on Ro ⁇ tor the external rotor motor.
- a detachable connection is therefore advantageous because the rim is exchanged ⁇ who can, without simultaneously replacing the rotor of the external rotor motor.
- the external rotor motor extends approximately completely over the rim mouth width of the sleeve-shaped rim.
- the space for the external rotor motor is not limited or limited by a rim star and a wheel key of the drive ⁇ wheel.
- a sleeve-shaped rim which is integrally formed.
- a rim of the tubular rim rim is formed as a flange ⁇ , wherein the flange is connected by means of the releasable connection directly and torque-locking with the rotor.
- the sleeve-shaped rim is designed as Tiefbettfelgenkranz (Tiefbettfelge).
- the rim base of the deep rim rim is screwed torque-tight directly to the rotor of the external rotor motor. This advantageously a technically efficient and cost-effective ⁇ drive for a motor vehicle, particularly for an electric motor vehicle, allows.
- a perimeter brake which comprises a brake disc, wherein the brake disc is frictionally connected or coupled to the sleeve-shaped rim or the rotor.
- the space within the tubular rim is not or only slightly limited by the perimeter brake, so that said space can be used almost completely for the external rotor motor and thus for the wheel hub drive of the drive wheel.
- the perimeter brake comprises at least one caliper which is connected to egg ⁇ ner axis of the drive wheel.
- the brake caliper of the perimeter brake is supported on the axis of the drive wheel which is connected to the motor vehicle.
- supply lines for controlling and / or cooling the perimeter brake and / or the external rotor motor can run through the axis of the drive wheel connected to the motor vehicle in a rotationally fixed manner.
- a hollow axle may be provided as an axle, so that the supply lines for the drive wheel of the motor vehicle extend protected within the hollow axle.
- a cooling device is provided.
- the cooling device may include cooling lines that directly the brake disc, the caliper, the rotor and / or
- Cool stator windings of a stator of the external rotor motor This advantageously prevents heating of the rim crane ⁇ and / or the rotor by the rim rim or the rotor coupled to the perimeter brake by a braking operation or by a plurality of braking operations.
- the brake disc is frictionally connected via a brake bridge with the sleeve-shaped Fel ⁇ genkranz or the rotor, wherein the brake bridge comprises at least one material having a high thermal resistance.
- the perimeter brake attached to the tubular rim or the rotor is thermally decoupled from the rim or the rotor. This additionally ensures that the rim or the rotor are not disproportionately heated by a braking operation or a plurality of braking operations.
- a bursting of a tire of the drive wheel which tire is fixed by the sleeve-shaped wheel rim on the driving wheel and enclosed by these, ver ⁇ avoided.
- the drive wheel comprises a sealing plate or a bearing plate, wherein a sealing diameter of the sealing plate or a bearing diameter of the bearing plate is arranged on an axis of the drive wheel.
- the seal of the drive wheel and / or the external rotor motor takes place on the smallest possible radial diameter.
- This advantageously the web speed at the location of the seal reduces relationship ⁇ as minimized as possible, so that a smaller Reibmo ⁇ ment results.
- Reibungsver ⁇ losses and wear of the seal are advantageously reduced.
- Figure 1 is a schematic representation of a drive wheel with an external rotor motor, a sleeve-shaped rim and a perimeter brake, wherein a brake disc of the perimeter brake is frictionally connected to the rim ⁇ wreath;
- Figure 2 is a schematic representation of a drive wheel with an external rotor motor, a sleeve-shaped Rim rim and a perimeter brake, wherein a brake disc of the perimeter brake is non-positively connected to a rotor of the external rotor motor. Similar elements may be provided in the figures with the same reference numbers ⁇ Be.

- the sleeve-shaped rim 2 is according to the invention by means of a releasable connection 42, in particular by means of a screw, directly and torque-connected to the rotor 6 of the external rotor motor 4.
- the rim 2 is formed as Tiefbettfelgenkranz, wherein a rim 8 of the Tiefbettfelgenkranzes 2 forms a flange which is connected by means of the releasable connection 42 with the rotor 6.
- the rotor 6 of the external rotor motor 4 is supported via bearings 22 on one with a motor vehicle - vehicle ⁇ is not Darge - associated axis 16 of the drive wheel 1 from.
- a sealing plate 26 or a bearing plate 26, which is supported via a further bearing 22 on the axis 16, may be provided on the side facing away from the motor vehicle on ⁇ drive wheel 1.
- the seal plate 26 or the bearing plate 26 may be connected to the rotor 6.
- a space 24 is limited within the rim 2, the axial length is approximately over the entire rim width 100 of the Fei- genkranzes 2 extends.
