Abstract
The utility model discloses a hub driving structure for an electric motor car, comprising a hub inner shaft, an electric motor, a pinion and a large gear ring. The electric motor is arranged on one side of the hub inner shaft, the pinion is arranged on the shaft of the electric motor, and the large gear ring is installed on the inner side of the hub. The teeth ends of the pinion are engaged with the large gear ring, the pinion driven by the electric motor drives the rotation of the large gear ring, and the rotation of the hub is driven. The utility model is different to the prior art, the difference lies in that the large torsional moment drive of the hub can be realized by a light and small electric motor, and the manufacturing cost of the hub is reduced.
Description
Technical field
The utility model relates to a kind of electric vehicle hub drive configuration.
Background technology
The eccentric wheel drive structure of prior art mainly adopts the wheel hub mode, and the wheel hub motor that is driven by high-speed electric expreess locomotive has the big advantage of the torque of driving, and the defective of this drive configuration is a complex structure, requirement on machining accuracy height, cost height.
The utility model content
The purpose of this utility model provides a kind of wheel hub and drives new structure, and this structure can only need small-sized motor can carry out big torsion driving, has overcome common wheel hub motor complex structure, defect of high cost simultaneously.
For achieving the above object, the utility model adopts following technical scheme: a kind of wheel hub drive configuration, this structure mainly is made up of axle, motor, miniature gears and large gear ring in the wheel hub, a side of axle is installed with motor in the wheel hub, on the axle of motor miniature gears is installed, large gear ring is installed on the inboard of wheel hub, miniature gears increment and the engagement of large gear ring coupling, and the motor-driven miniature gears drives the large gear ring rotation.
A side of axle is installed with motor in the described wheel hub, and opposite side is installed with controller and battery.
Described control device is fixed in the wheel hub on the adapter plate on the axle.
Described cell apparatus is fixed in the wheel hub on the adapter plate on the axle.
Described motor can be pillar motor or disc type electric machine.
Described large gear ring is installed on the wheel hub inboard, closes with the inboard card of wheel hub.
Described large gear ring is installed on the inboard, one side of wheel hub.
In one port of described hub spindle the DC charging socket is installed, socket charges to battery by being wired to battery controller.
Because adopt technique scheme, the utility model compared with prior art has following advantage:
1, the utility model by the rotation of miniature gears direct drive large gear ring, has been realized efficient rotation by electric machine, has alleviated weight simultaneously, has reduced cost;
2, the utility model can internal battery, controller and motor, realized that global function is located at one.

Figure one is the scheme drawing of this novel hub drive configuration;
Figure two is axial ingear scheme drawing for the large and small gear of this novel hub drive configuration;
Figure three is another embodiment scheme drawing of this novel hub drive configuration;
Figure four is radially ingear scheme drawing for the large and small gear of this novel hub drive configuration.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figures 1 to 4, a kind of electric wheel hub structure is made up of large gear ring 3, miniature gears 4 and motor 6, large gear ring 3 is installed on the inboard of hub shell 2, miniature gears 4 is installed on the axle 5 of motor 6, miniature gears 4 increments and large gear ring 3 coupling engagements, motor 6 Drive pinions 4 drive large gear ring 3 rotations, and motor 6 can drive big gear wheel through behind the primary gear speed reducing more certainly, to obtain higher reduction ratio.
Described large gear ring 3 can be direct tooth type outer direct tooth type, interior (as Fig. 2) or umbrella flute profile (as Fig. 4).
Be installed with connecting panel 8 on the axle 9 in the wheel hub, motor 6 is installed on the connecting panel 8, and this novel hub drive configuration can also be installed in controller 13, battery pack 12 in the hub shell 2, thereby has constituted the wheel hub structure of global function in one.
Controller 13 is by lead 11 control motors 6.
Motor lines can be drawn by hole, hub spindle 9 interior lines in the hub shell 2.
This novel hub drive configuration can also will be equipped with DC charging socket 10 in hub spindle 9 one ends, socket 10 charges to battery by being wired to battery controller, on the axle 9 of motor 6 miniature gears 4 is installed, miniature gears 4 and large gear ring 3 coupling engagements, motor pinion 4 drives large gear ring 3 and drives the wheel hub rotation.
In addition, this novel hub shell 2 can be connected with rim 1 with spoke, also can make hub shell 2 and rim 1 become one by integrated mode.
