Description
Technical field
The utility model relates to the electronic rear axle power assembly of a kind of pure electric automobile wheel motor, belongs to pure electric automobile equipment technical field.
Background technology
At present, the conventional drive scheme of pure electric automobile is generally employing motor direct-drive back axle or adds change speed gear box and arrive back axle again, uses mechanical differential device.The rear axle power assembly of this structure, easily causes high-rate battery discharge, reduces service life of battery, simultaneously mechanical differential Heavy Weight, and driving efficiency is lower and have noise.
Utility model content
The utility model object is to provide the electronic rear axle power assembly of a kind of pure electric automobile wheel motor, the power that two motors produce is input in the planetary reducer of both sides respectively, output power in wheel by the half-bridge of both sides again, solve Problems existing in background technology.
The technical solution of the utility model is:
The electronic rear axle power assembly of a kind of pure electric automobile wheel motor, comprise left wheel, half-bridge one, planetary reduction gear one, motor one, motor two, planetary reduction gear two, half-bridge two and right wheel, motor one and motor two are arranged side by side, the output shaft of motor one and motor two is in transmission connection with the planetary reduction gear one of both sides and planetary reduction gear two respectively, planetary reduction gear one and planetary reduction gear two drive respectively by the left wheel of half-bridge one and half-bridge two and both sides and right wheel and are connected, and are overallly arranged symmetrically with in a row.
Described motor one is connected by spline drived with the planetary reduction gear one of both sides and planetary reduction gear two with the output shaft of motor two.
The electronic rear axle power assembly of above-mentioned pure electric automobile wheel motor, adopt electronic differential, by fuzzy control theory, self adaptation is carried out to motor one and motor 2 two motors and determines direct torque, make electronlmobil exercise complex road surface or spin to time realize differential function, improve drive system efficiency.
Adopt the utility model, motor one and motor 2 two motors are adopted to drive back axle, its peak current magnitude is 1/2 of rated current, the outgoing current peak value of battery is also 1/2 of former rated motor, and frequency adds one times, therefore, the discharge peak currents of battery also only has 1/2 of rated current peak value.
The beneficial effects of the utility model are: the heavy-current discharge avoiding battery, improve the degree of utilization of battery, extend the service life of battery.Integral structure is simple, firm, volume is little, lightweight, driving efficiency is high, energy-conservation, improve course continuation mileage.

Fig. 1 is the utility model structural representation;
In figure: left wheel 1, half-bridge 1, planetary reduction gear 1, motor 1, motor 25, planetary reduction gear 26, half-bridge 27, right wheel 8.
Detailed description of the invention
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
With reference to accompanying drawing 1, the electronic rear axle power assembly of a kind of pure electric automobile wheel motor, comprise left wheel 1, half-bridge 1, planetary reduction gear 1, motor 1, motor 25, planetary reduction gear 26, half-bridge 27 and right wheel 8, motor 1 and motor 25 are arranged side by side, the output shaft of motor 1 and motor 25 is in transmission connection with the planetary reduction gear 1 of both sides and planetary reduction gear 26 respectively, planetary reduction gear 1 and planetary reduction gear 26 drive respectively by the left wheel 1 of half-bridge 1 and half-bridge 27 and both sides and right wheel 8 and are connected, and are overallly arranged symmetrically with in a row.
In the present embodiment, motor 1 is connected by spline drived with the planetary reduction gear 1 of both sides and planetary reduction gear 26 with the output shaft of motor 25.And this dynamic assembly cancels traditional mechanical differential, adopt electronic differential.By fuzzy control theory, self adaptation is carried out to two motors and determines direct torque, make electronlmobil exercise complex road surface or spin to time realize differential function, its differential effect is the same with traditional mechanical differential, can improve drive system efficiency.
