Preferably, each external rotor electric machine includes wound stator and outer rotor.Wound stator is fixed on coaxial.Outer rotor
It is arranged at outside wound stator and be installed on coaxial.The preferred permanent-magnetic outer rotor of described outer rotor.
Preferably, the wound stator of described external rotor electric machine and coaxial on be respectively arranged with keyway and fixed by locked key
In the keyway and described wound stator is fixed on described coaxial on.
Preferably, the outer rotor of described external rotor electric machine by bearing be installed in described coaxial on.
Preferably, described coaxial on be provided with axially extended cable hole, wherein, described institute coaxial Yu mounted thereto
State external rotor electric machine corresponding position and be provided with wire casing, the wire harness of described external rotor electric machine enters described coaxial interior by wire casing and wears
Cross described cable hole to draw.
Preferably, described external rotor electric machine is additionally provided with a lid, and this lid and described outer rotor are removably attached to one
Rise, described lid by bearing be installed in described coaxial on.
As described above, at least two external rotor electric machines of drive wheel group of the present invention be arranged at same coaxial on, adjacent two outer turn
The distance between sub-motor can reduce to greatest extent, and this allows the volume of drive wheel group to become very little, thus taking
Less space, this adapts in the environment needing multiple Motor drives and insufficient space.
Brief description
Fig. 1 is the perspective view of drive wheel group embodiment 1 of the present invention；

In the present embodiment, it is provided with coaxial keyway 11 on coaxial 10, wound stator is provided with stator keyway 211.Altogether
It is fixed with locked key 30, thus wound stator is fixed on coaxial 10 in shaft key groove 11 and stator keyway 211.Wound stator is also
Can be fixed on coaxial 10 in the way of direct welding, actually other any can make wound stator be fixed on coaxial 10
Mode.
Outer rotor 22 has Magnet, is installed on coaxial 10 and is arranged at outside wound stator.Outside the preferred permanent magnetism of outer rotor 22
Rotor.
In the present embodiment, outer rotor 22 has support 221, and the support 221 of outer rotor 22 is installed in altogether by bearing 40
On axle 10.The support 221 of outer rotor 22 can also directly be installed on coaxial 10, and actually no matter direct or indirect other are any
The mode that outer rotor 22 is installed on coaxial 10 can be made.
In order to dust-proof further, external rotor electric machine 20 is additionally provided with a lid 23.Lid 23 is removably solid with outer rotor 22
It is scheduled on together, lid 23 is installed on coaxial 10 by bearing 40.Certainly, lid 23 also can be integrally formed with outer rotor 22.
Preferably, it is provided with axially extended cable hole 12 on coaxial 10, wherein, coaxial 10 is each with mounted thereto
External rotor electric machine 20 corresponding position is provided with wire casing 13, and the wire harness 50 of each external rotor electric machine 20 enters coaxial 10 by wire casing 13
Interior and draw through cable hole 12, this can facilitate cabling, save space.Certainly, the wire harness of external rotor electric machine 20 can also pass through
Gap between external rotor electric machine 20 is drawn.
Operationally, electric power is respectively supplied to the winding of each external rotor electric machine 20 by wire harness 50 to drive wheel group of the present invention
Stator, the coil of wound stator produces induction field, the magnetic field that the outer rotor 22 outside this induction field and wound stator produces
Mutually repel, this makes outer rotor 22 produce rotation.
Each external rotor electric machine 20 of drive wheel group can independently run, and the outer rotor of each external rotor electric machine 20 turns
Speed can be respectively provided with different rotating speeds as needed, controls the control panel of each external rotor electric machine can be arranged at driving wheel
