Abstract
The invention relates to a highly energy-saving four-motor balance and exchange drive mechanism of an electric vehicle, which is driven by four hub motors at the same time. The four hub motors are controlled by four controllers and a speed governor to adjust the speed of the motors, so as to be enabled to work synchronously. When the electric vehicle makes a turn, since the four motors are simultaneously stressed by different forces, electronic differential control is realized by the controllers, adaptive control is realized and the driving is enabled to be safer.
Description
Principle of work
Balance drives; Aerotron in governor receives the effect in magnetic field, spreads out of current signal to four controllers, and four controllers receive signal simultaneously and control four motors thereupon respectively and do synchronous working.
Exchange drives: the four wheel drive mode, when turning, because of four motors receive varying in size of resistance simultaneously, realize electronic differential, adaptive control by controller.Make driving safer.
The circuit advantage
(1) energy-efficient
(2) do not have these drive mechanisms of gear or chain, save back axle, significantly reduced fault rate, reduce manufacturing cost.
(3) reduced noise
(4) stability of raising car load
(5) favourable realization electric brake removes mechanical brake, labor and material saving.
Affiliated technical field
The present invention is applicable to electrocar, electronic utility van, electrobus, electronic big bus, electric goods car.
Technical background
At present, known electrocar or medium and heavy loading carrying battery-driven car all are by high-performance mid-motor-driven, by gear transmission.But high-power mid-motor torque is little, consumption of current big, gear transmission also increases consumption of current, and noise is big.Big, the energy-conservation consumption of current of wheel hub motor torque is low, but the wheel hub motor maximum power is limited, can't reach the needed power of electrocar.
Summary of the invention
Big in order to overcome in the prior electric car centrally-mounted driving consumption of current; And wheel hub motor power is little; The present invention adopts four wheel hub motors to do rear drive or front and back drive, and four wheel hub motors just can satisfy electrocar or the needed power of medium and heavy loading carrying battery-driven car.
