Embodiment
Fig. 1 show the structural representation of the electric drive axle of the first specific embodiment of the present utility model.As shown in figure 1,
Electric drive axle, including：Driving axle housing 10 and at least a motor 20；Motor 20 is substantially vertical with its rotation axis Z
Mode in level ground 30 is installed on driving axle housing 10.
" substantially vertical " means that the angle between the rotation axis Z of motor 20 and the vertical line of level ground 30 is not more than
15 degree, to meet other design requirements such as arrangement and ensure that the quality of motor 20 is relatively evenly distributed in driving axle housing 10
Front and rear sides.
Fig. 2 show the structural representation of the electric drive axle of the second specific embodiment of the present utility model.As shown in Fig. 2
The inside of driving axle housing 10 is additionally provided with main reducing gear 101 and differential mechanism 102, and main reducing gear 101 includes at least one bevel pinion
1011 and bevel gear wheel 1012；Motor 20 includes stator bracket 201 and rotor spider 202, stator bracket 201 and drive axle
Shell 10 is fixedly connected；Bevel pinion 1011 is fixedly connected with rotor spider 202, and bevel gear wheel 1012 is fixed with differential mechanism 102 to be joined
Connect, the power of motor 20 is delivered on wheel.
Bevel pinion 1011 and bevel gear wheel 1012 can be straight bevel gear or spiral bevel gear, Huo Zhezhun
Hyperboloid bevel gear.Other kinds of driving and driven Gear axis intersect at a point, or driving and driven Gear axis it is non-intersect and
It is also possible in the space crossed kind of drive, it is not limited thereto system.
The inside of motor 20 is provided with a cavity 210, to accommodate the one of bevel pinion 1011 and bevel gear wheel 1012
Part.In order that obtaining more compact structure, loop configuration is made in the inside of motor 20, i.e. its one cavity 210 of internal setting, with
A part for bevel pinion 1011 and bevel gear wheel 1012 is contained in wherein, but is not limited thereto system.
Rotor spider 202 is cup-like structure, and its inner space forms cavity 210.I.e. bevel pinion 1011 is installed in rotor
The inside for the cavity that the cup-like structure of bracket 202 is formed, a part of structure of the bevel gear wheel 1012 near meshing point are also placed in
Wherein.If using external rotor electric machine, 201 structure annular in shape of stator bracket, cavity 210 is by stator bracket 201
Portion space and rotor spider 202 surround, but are not limited thereto system.
Motor 20 also includes motor bearings 203, and it is installed between stator bracket 201 and rotor spider 202.Due to
