Abstract
Four four-wheel-driven brushless non-hub motors are adopted as power of four wheels for overcoming the defects that the turning diameter of an electric vehicle is large. When the electric vehicle turns towards the left, the two left wheels turn inversely, the two right wheels turn forwards, and the four wheels simultaneously rotate at the same speed forwards and inversely; when the electric vehicle turns in 180 degrees, the turning diameter is zero. Through the method that a controller changes the phase positions of the non-hub motors and changes working points of Hall lines, inverse rotating is achieved, and the speed of inverse rotating is equal to that of forward rotating.
Description
Principle of work:
Battery-driven car is generally divided into electric motor car with two wheels, three-wheeled electric vehicle and four-wheel electric motor car, and the motor of electric vehicle adopts brush motor and brushless motor two kinds usually.On four-wheel electric motor car, this invention install on four wheels four brushless without hub motor, when needs battery-driven car passes through turning backward going, now four-wheel electric motor car angle of turn 180 °: if turned left: two, the left side wheel of four-wheel electric motor car realizes reversion, two wheels on the right rotate forward, two wheels rotated forward and two wheel speeds of reversion must be equal, and synchronized rotation simultaneously, just can realize turning-circle diameter is zero.
Brushless without in hub motor-drive circuit four-wheel electric motor car four: by changing corresponding lines connection and Cui Er line mode of connection, realizing turning-circle diameter is zero.
When the brushless battery-driven car without hub motor of needs four is by turning backward going, now this four-wheel electric motor car angle of turn is 180 °, if turned left, two of the left side brushless without hub motor reversal, two of the right brushlessly rotate forward without hub motor, and reverse and forward is brushless, and the speed simultaneously same without hub motor is rotated, and just can realize turning-circle diameter is zero.
Art:
The present invention is applicable to four-wheel electric motor car.
Technical background:
At present because battery-driven car and self-propelled vehicle all also exist turning-circle diameter greatly, directly can not turn under many circumstances, have impact on traveling.
Summary of the invention:
Large for overcoming electric vehicle rotary bend diameter, four that present invention employs four wheel drive brushless without the power of hub motor as four wheels, if when turning left, two, left side wheel reversing, two, the right wheel rotates forward, and synchronized rotation while that four wheels being positive and negative, turn 180 ° time, turning-circle diameter is zero.
By controller to changing phase place and the method to Cui Er change operation point without hub motor, realize reversion, and and rotate forward constant speed.
Below in conjunction with accompanying drawing and enforcement, practicality invention is further illustrated:
Figure of description 1 is that a kind of four-wheel is brushless brushless without hub machine operation schematic diagram without a group of hub motor.
In accompanying drawing 1: V1 controller, N1 is brushless without hub motor, and A1 controller exports positive 5V, red line, A2 ground wire, negative electricity black line, A3 yellow line Cui Er line, A4 blue line, Cui Er line, A5 green line, Cui Er line, the yellow corresponding lines of B1, B2 blue phase line, the green corresponding lines of B3.
Realize brushless without hub motor reversal method 1: change switch by forward and backward revolution, exchange A4, A5 Cui Er line, exchange corresponding lines B2B3, just can realize reversion, and the speed of reversion is equal with positive rotary speed.
Realize brushless without hub motor reversal method 2: change switch by forward and backward revolution and exchange A1 and meet A3, A3 and meet A2, A2 and meet A1, exchange corresponding lines connection B1, B3, just can realize reversing, and it is equal to rotate and reverse speed.
Technical characteristic:
When turnon left 180 °, can realize reversing because this invention can realize two, left side wheel, two, the right wheel rotates forward, and energy synchronized positive and negative four rotations taken turns simultaneously, just can realize turning-circle diameter is zero.
