Abstract
The utility model discloses an independent drive system of a double-hub motor of an electric automobile. The independent drive system of the double-hub motor of the electric automobile comprises a steering wheel, a steering booster, a controller, batteries, two front automobile wheels, two rear wheel motors and two drivers, the steering booster is connected with the steering wheel, the controller and the two front automobile wheels, the controller is connected with the batteries, the batteries are respectively connected with the two drivers, and each of the two drivers is connected with the corresponding rear wheel motor. The independent drive system of the double-hub motor of the electric automobile overcomes the disadvantages of the prior art and has advantages of light chassis, good maneuverability, high accelerated speed, reliable performance, low failure rate, long service time, long continuous range and so on.
Description
Technical field
The utility model belongs to automobile driving system field, particularly a kind of electronlmobil double wheel hub motor independent driving system.
Background technology
Along with social development, the car owning amount of China is increasing, and environmental pollution, energy shortage problem are also day by day serious.But current electronlmobil is also in continuation conceptual phase, present stage exist electronlmobil integral structure all undesirable, its reason is: complex structure, chassis is overweight, cost is high, power consumption too large.The pond energy storage of electronlmobil vehicle mounted electric very little, is unable to undergo that diff, change speed gear box etc. are overweight, the waste of too many structure of consuming energy, thereby causes electronlmobil mileages of continuation too short.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of electronlmobil double wheel hub motor independent driving system, overcome the deficiencies in the prior art, had that chassis is light, manoevreability good, acceleration/accel is high, a dependable performance, failure rate is low, long service life, the advantage such as mileages of continuation is long.
To achieve these goals, the utility model is by the following technical solutions:
A kind of electronlmobil double wheel hub motor independent driving system, comprises bearing circle, direction servo-unit, controller, battery, two vehicle fronts, two rear-wheel motors and two actuators; Described direction servo-unit is closure dish, controller and two vehicle fronts respectively, and controller connects battery, and battery is connected with two actuators respectively, and two actuators connect respectively corresponding rear-wheel motor.
As preferably, the front-wheel control of described vehicle front adopts electric boosting steering system.
The beneficial effects of the utility model are:
The control of the utility model front-wheel adopts electric boosting steering system EPS, and power is provided jointly by two rear-wheel motors.Electric power steering drives and uses conventional DC servomotor, controls simple.Two rear-wheel motors are two hub-type brush DCs (BLDC) motors, can in raising the efficiency, guarantee the reliability of long-time running.In system, between each motor and controller (ECU), form alone a speed closed loop and current closed-loop system, this design can keep orthodox car to drive on the basis of sense, the parts such as power-transfer clutch, change-speed box, main reduction gear and the diff of omission conventional truck, simplify to a great extent complete vehicle structure, improved driving efficiency.The utlity model has that chassis is light, manoevreability good, acceleration/accel is high, dependable performance, failure rate is low, long service life, the advantage such as mileages of continuation is long.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on will be apparent to those skilled in the art to investigating below, or can from practice of the present utility model, be instructed.Target of the present utility model and other advantages can be by below specification sheets or accompanying drawing in specifically noted structure realize and obtain.
Accompanying drawing explanation
Fig. 1 is structured flowchart of the present utility model.
The specific embodiment
Below by specific embodiment, and by reference to the accompanying drawings, preferred embodiment of the present utility model is described in detail.
As shown in Figure 1, the utility model comprises bearing circle 1, direction servo-unit 2, controller 3, battery 4, two vehicle fronts 7, two rear-wheel motors 6 and two actuators 5.Bearing circle 1 closure servo-unit 2, direction servo-unit 2 connects respectively controller 3 and two vehicle fronts 7, and controller 3 connects battery 4, and battery 4 is connected with two actuators 5 respectively, and two actuators 5 connect respectively corresponding rear-wheel motor.Rear-wheel motor adopts hub-type DC brushless motor 6.
The control of the utility model front-wheel adopts electric boosting steering system EPS, and power is provided jointly by two rear-wheel motors.Electric power steering drives and uses conventional DC servomotor, controls simple.Two rear-wheel motors are two hub-type brush DCs (BLDC) motors, can in raising the efficiency, guarantee the reliability of long-time running.In system, between each motor and controller (ECU), form alone a speed closed loop and current closed-loop system, this design can keep orthodox car to drive on the basis of sense, the parts such as power-transfer clutch, change-speed box, main reduction gear and the diff of omission conventional truck, simplify to a great extent complete vehicle structure, improve driving efficiency, and can realize servo-steering function and the Electronic differential control to electric drive wheel by control technology, make it reach the purpose of this utility model.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, other modifications that those of ordinary skills make the technical solution of the utility model or be equal to replacement, only otherwise depart from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of claim scope of the present utility model.
